'''Bartholomew Henry "Barry" Allen''' is a <!--Do not add "fictional" as it is tautological; superheroes (and characters in general) are by definition implied to be fictionalized to some extent.-->[[superhero]] appearing in [[American comic books]] published by [[DC Comics]]. He is the second character known as [[the Flash]], following [[Flash (Jay Garrick)|Jay Garrick]]. The character first appeared in ''[[Showcase (comics)|Showcase]]'' #4 (October 1956), created by writer [[Robert Kanigher]] and penciler [[Carmine Infantino]].<ref name="dc-ency">{{Cite book| last = Jimenez | first = Phil | author-link = Phil Jimenez | contribution = The Flash | editor-last = Dougall | editor-first = Alastair | title = The DC Comics Encyclopedia | pages = 124–127 | publisher = [[Dorling Kindersley]] | place = New York | year = 2008 | isbn = 978-0-7566-4119-1 | oclc = 213309017}}</ref> A forensic chemist, Barry accidentally gains superpowers following a lightning strike in his laboratory. Like other heroes who go by the Flash, Barry is a "[[Speedster (fiction)|speedster]]", with powers that derive mainly from his superhuman speed. He wears a distinct red and gold costume treated to resist friction and wind, traditionally storing the costume compressed inside a ring.

Created as a reimagining of the popular 1940s superhero [[Flash (Jay Garrick)|The Flash (Jay Garrick)]], the success of Barry Allen's ''Flash'' comic book helped to bring about the [[Silver Age of Comic Books]] and contributed to a large growth in DC Comics' stable of [[science fiction]] comics and characters. During popular early volumes as the Flash, Barry established his own [[Rogues (comics)|Rogues Gallery]] of colorful villains and sci-fi concepts like Gorilla City. Through crossovers with popular characters like [[Superman]], [[Wonder Woman]], and [[Batman]], Barry Allen's Flash also helped establish DC's flagship [[Justice League]] title, whose success would define its publishing strategy for decades to come.

Barry Allen's classic stories also introduced the concept of the [[Multiverse (DC Comics)|Multiverse]] to DC Comics, which has played a large part in DC's many [[reboot (fiction)|continuity reboots]] over the years. As a result, the Flash has traditionally always had a significant role in DC's major company-wide crossover stories, and in the crossover ''[[Crisis on Infinite Earths]]'' #8 (November 1985), Barry Allen died saving the Multiverse and would not appear again for 23 years. His return to regular comics is foreshadowed during [[Grant Morrison]]'s crossover story ''[[Final Crisis]]'' #2 (June 2008), preceding his full return in [[Geoff Johns]]' accompanying ''[[The Flash: Rebirth]]'' (June 2009) [[Limited series (comics)|limited series]]. He has since played a pivotal role in the crossover stories like ''[[Blackest Night]]'' (2009), [[Flashpoint (comics)|''Flashpoint'']] (2011), [[Convergence (comics)|''Convergence'']] (2015), ''[[DC Rebirth]]'' (2016), ''[[Doomsday Clock (comics)|Doomsday Clock]]'' (2017–2019), ''[[Infinite Frontier]]'' (2021), and ''[[Absolute Power (comics)|Absolute Power]]'' (2024).

Barry Allen is an established [[pop culture]] icon and has been featured in several media, first appearing in animated form in the 1967 ''[[The Superman/Aquaman Hour of Adventure]]'' and then in the related ''[[Super Friends]]'' program. Since then he has appeared in several [[DC Universe Animated Original Movies]]. Actor [[John Wesley Shipp]] portrayed the character in the live-action 1990s television show ''[[The Flash (1990 TV series)|The Flash]]'' and the [[Arrowverse]]. The [[Barry Allen (Arrowverse)|character]] was portrayed by [[Grant Gustin]] in the [[Arrowverse]] shows in a main capacity, especially the 2014 television series ''[[The Flash (2014 TV series)|The Flash]]'', while [[Ezra Miller]] portrayed the [[Barry Allen (DC Extended Universe)|character]] in the [[DC Extended Universe]] films ''[[Batman v Superman: Dawn of Justice]]'', ''[[Suicide Squad (2016 film)|Suicide Squad]]'', ''[[Justice League (film)|Justice League]]'', the director's cut ''[[Zack Snyder's Justice League]]'', the Arrowverse event ''[[Crisis on Infinite Earths (Arrowverse)|Crisis on Infinite Earths]]'', the HBO Max series ''[[Peacemaker (TV series)|Peacemaker]]'', and the 2023 film ''[[The Flash (film)|The Flash]]''.

==Publication history==
{{See also|The Flash (comic book)#Publication history|The Brave and the Bold#Publication history|Justice League#Publication history}}

While the fictional "in world" history of the character known as "The Flash" has been written and rewritten many times as DC Comics rebooted their fictional worlds again and again, the publication history of the character has followed a different path, not (quite) so prone to rewriting.

The Flash, Barry Allen (the name ''Bartholomew'' was not used until much later), first appeared in print in ''[[Showcase (comics)|Showcase]]'' #4 (October 1956). The creative team on Showcase #4 consisted of [[Julius Schwartz|Julie Schwartz]] (editor), [[Robert Kanigher]] (writer), [[Carmine Infantino]] (penciler, i.e., illustrator), and Joe Kubert (inker, i.e., assistant illustrator). Robert Kanigher is on record as saying he still considers Gardner Fox as "the creator of The Flash", and his creation of Barry Allen is a reworking of that original work. As a result, no one name is easily identifiable as the character's creator.<ref>[https://twomorrows.com/alterego/articles/10flash.html twomorrows.com - Alter Ego Edited by Roy Thomas - From Alter Ego Vol. 3 #10 - Who Created the Silver Age Flash?]</ref>

Fox's superhero, "The Flash" first appeared in Flash Comics #1 in 1940. In this story the man in the costume (he wore no mask) was named Jay Garrick. He rose in popularity and appeared in four comic book titles.

After World War II, superheroes declined in popularity, causing many of the Flash's comic book series to be canceled. All-Flash was canceled in 1948 after 32 issues and Comic Cavalcade became a talking animal humor book. Flash Comics was canceled in 1949 after 104 issues. All-Star Comics was canceled in 1951 after 57 issues, marking Garrick's last Golden Age appearance.

The popularity and circulation of comic books about superheroes had declined following World War II, and comic books about horror, crime and romance took larger shares of the market. However, controversy arose over alleged links between comic books and juvenile delinquency, focusing in particular on crime, horror, and certain elements of superheroes. In 1954, publishers implemented the Comics Code Authority to regulate comic content.

In the wake of these changes, publishers began introducing superhero stories again (as preferable to crime and horror), a change that began with the introduction of a new version of DC Comics' The Flash in Showcase #4 (October 1956).

In 1956, DC Comics reinvented the Flash character, giving him a new costume, name, and background. Carmine Infantino alleged the character design was from a [[Shazam (DC Comics)|Captain Marvel]] homage he created earlier dubbed Captain Whiz.<ref>{{cite magazine |last=Amash |first=Jim |date=July 2004 |title=How Captain Whiz Became the Flash |url=https://issuu.com/twomorrows/docs/alter_ego__38 |magazine=Alter Ego #38 |location=Raleigh, NC |publisher=TwoMorrows |access-date=August 17, 2023}}</ref> This new Flash, named Barry Allen, was completely unrelated to Jay Garrick. In fact, Garrick had never existed, as far as the new books were concerned. Barry Allen's first appearance shows him reading a copy of Flash Comics, lamenting that Garrick was "just a character some writer dreamed up". Readers welcomed the new Flash, but still had an interest in the old one. 1956's Showcase #4 featured two Flash stories, "Mystery of the Human Thunderbolt!", and "The Man Who Broke the Time Barrier!" During an era marked by rapid scientific advancements and Cold War anxieties, the stories in "Showcase #4" reflect contemporary themes of technological triumph and societal stability. "Mystery of the Human Thunderbolt!" introduces Barry Allen, a police scientist who gains super-speed powers, symbolizing the era's optimism about scientific progress and the need for heroes who embody justice. The inclusion of a bank robber as a villain resonated with readers due to prevalent fears about financial security and crime. "The Man Who Broke the Time Barrier!" parallels the groundbreaking achievement of breaking the sound barrier, exploring the potential of time travel influenced by Einstein's theories, and highlighting the fascination with overcoming natural limits through science.

Also introduced at this time was Iris West, Barry Allen's then love interest (and later wife), and "Lois Lane" to his "Clark Kent". Like Lois Lane, Iris West was a reporter, in this case for Picture News.

Wally West, the nephew of Iris West Allen, first appeared in Flash #110 (1959), which depicted his transformation into Kid Flash, the "Robin" to the Flash's "Batman". Wally West would later go on to become the new Flash many years later.

Jay Garrick made a guest appearance in 1961 in Flash #123 "[[Flash of Two Worlds]]". In this issue, Garrick was treated as residing in a parallel universe ([[Earth-Two]]), which allowed the character to exist without any continuity conflicts with Barry Allen (who existed on [[Earth-One]]), yet allowed him to make guest appearances in [[Silver Age of Comic Books|Silver Age]] books.

Barry Allen and Iris West were shown to get married in 1966 in ''Flash'' #165 "One Bridegroom Too Many!"<ref>[https://50yearoldcomics.com/2016/09/01/flash-165-november-1966/ 50yearoldcomics.com]</ref>

[[File:Showcase4.JPG|thumb|right|upright|''Showcase''#4 (October 1956): First appearance of the Silver Age Flash. Art by [[Carmine Infantino]] and [[Joe Kubert]].]]Barry Allen is a forensic [[chemist]] with a reputation for being very slow, and frequently late, which frustrates his fiancée, [[Iris West]]. One night, as he is working late on a new case, a lightning bolt strikes and shatters a case full of unspecified chemicals, drenching Barry, and temporarily knocking him out. As a result, Allen later finds that he can run at super-human speeds and possesses equally enhanced reflexes, senses, and healing. He later dons a red bodysuit, sporting a lightning bolt in the chest (reminiscent of the original [[Fawcett Comics]] [[Shazam (DC Comics)|Captain Marvel]]), dubs himself the Flash (after his childhood comic book hero, [[Flash (Jay Garrick)|Jay Garrick]]), and becomes [[Central City (DC Comics)|Central City]]'s resident costumed crime fighter and protector.<ref name="dc-ency"/>

Central City University professor Ira West (Iris's adoptive father) designed Allen's costume and the ring which stores it while Allen is in his civilian identity.<ref>{{Cite comic|Writer = Bates, Cary|Title = [[The Flash (comic book)|The Flash]]|Volume = |Issue = #267|Date = November 1978|Publisher = DC Comics}}</ref> The ring can eject the compressed clothing when Allen needs it and suck it back in with the aid of a special gas that shrinks the suit. In addition, Allen invents the '''cosmic treadmill'''<!--boldface per WP:R#PLA-->, a device that allows for precise [[time travel]]. Allen is warmly received by his superhero colleagues, so much so, that nearly all speedsters that come after him are often compared to him. [[Batman]] says "Barry is the kind of man that I would've hoped to become if my parents had not been murdered."<ref>''Justice'' #8 (Dec. 2006)</ref>

===Justice League===
As presented in ''Justice League of America'' #9, when the Earth is infiltrated by [[Extraterrestrial life|alien]] warriors sent to conquer the planet, some of the world's greatest heroes join forces, Allen among them. While the superheroes individually defeat most of the invaders, they fall prey to a single alien and only by working together are able to defeat the warrior. Afterwards, they decide to establish the [[Justice League]].

During the years, Barry is depicted as feeling slightly attracted to [[Black Canary]] and [[Zatanna]] but never pursues a relationship because he feels his real love is Iris West, whom he ultimately marries. Allen also becomes a good friend of [[Hal Jordan|Green Lantern (Hal Jordan)]], which would later be the subject of the limited series ''Flash and Green Lantern: The Brave and the Bold''.

In ''The Flash'' #123—"[[Flash of Two Worlds]]"—Allen is transported to [[Earth-Two]] where he meets Jay Garrick, the original Flash in DC Continuity; it is revealed that Jay Garrick's adventures were captured in comic book form on [[Earth-One]]. This storyline initiates DC's multiverse and is continued in issues of ''Flash'' and in team-ups between the Justice League of America of Earth-One and the [[Justice Society of America]] of Earth-Two. In the story from ''Flash'' #179—"The Flash&nbsp;– Fact or Fiction?"—Allen is thrown into the universe called [[Earth Prime]], a representation of "our" universe, where he seeks the aid of the ''Flash'' comic book's editor [[Julius Schwartz]] to build a cosmic treadmill so that he can return home. He also gains a sidekick and protégé in Iris' nephew, [[Wally West]], who gains super-speed in an accident similar to that which gave Allen his powers.

===Tragedy===
In time, Barry marries his girlfriend Iris West, who learns of his double identity because Allen talks in his sleep. She keeps this secret, and he reveals his identity to her of his own free will with Moreno's persuasion.<ref>''The Flash'' #174</ref> Iris is revealed to have been sent as a child from the 30th century and adopted.

In the 1980s, Flash's life begins to collapse. Iris is murdered by [[Eobard Thawne|Zoom]] (a supervillain from the 25th century who had long loved her and been jealous of Allen), and when Allen prepares to marry another woman, Zoom tries the same trick again. Allen stops him, killing Zoom in the process by breaking his neck. Unfortunately, when Barry is unable to make an appearance at his own wedding, his fiancée descends into madness.

Placed on trial for murder in connection with Zoom's death, Allen is found guilty by the jury. When he is told by a juror Nathan Newbury, who is being possessed by a mind from the future, that Reverse-Flash (whom Allen knows to be dead) brainwashed the jury into this verdict, Flash flees his trial. The Flash is then attacked by Reverse-Flash, and realizes that the answers to this mystery, and restoring his good name, lie in the future, so Newbury uses a time device to send them forward. They discover that [[Abra Kadabra (character)|Abra Kadabra]] was disguised as Reverse-Flash to ruin the Flash's good name. Defeating Kadabra, he retreats to the future to be reunited with Iris, having learned that Iris' spirit was in fact drawn to the 30th century, and given a new body (and was in fact the mind inhabiting Newbury). The final issue of ''The Flash'' ends with Flash and Iris kissing passionately and the caption "And they lived happily ever after... for a while". There are a few references in the final issue (''The Flash'' #350) to the upcoming events, and Flash's impending death.<ref name="dc-ency"/>

In the controversial storyline ''[[Identity Crisis (DC Comics)|Identity Crisis]]'' (set within the post-''[[Zero Hour: Crisis in Time!|Zero Hour]]'' continuity), it is revealed that six months after Iris' death, Barry and four other members of the Justice League voted to allow [[Zatanna]] to edit [[Doctor Light (Arthur Light)|Doctor Light]]'s mind, essentially lobotomizing him. When Batman discovers what the League was doing, the League has his memories edited as well despite the objection of [[Green Arrow]]. Both Doctor Light and Batman recover from their respective mindwipes; Doctor Light vows to get his revenge against the heroes while Batman loses trust and faith in his allies.

===''Crisis on Infinite Earths''===
{{Main|Crisis on Infinite Earths}}
Following the trial, Allen retires and joins Iris in the 30th century. After only a few weeks of happiness, the ''Crisis on Infinite Earths'' intervenes, and Allen is captured by the [[Anti-Monitor]] and brought to 1985; according to the Anti-Monitor, the Flash is the only being capable of traveling to other universes at will, so the Anti-Monitor could not allow him to stay free. Allen escapes and foils the Anti-Monitor's plan to destroy the Earth with an anti-matter cannon, creating a speed vortex to draw the power in, but dies in the process as the power becomes too much for his body.<ref name="dc-ency"/> It has been said that Allen travels back through time and becomes the very same lightning bolt that gives him his powers, but later it is also strongly implied that the soul of Barry resides in the [[Speed Force]], the mystical source and Valhalla open to all dead speedsters, and from which the living ones draw their powers. After Allen's death, Kid Flash [[Wally West]], his nephew and sidekick, takes up the mantle of the Flash.<ref>{{Cite comic|Writer = [[Marv Wolfman|Wolfman, Marv]]|Title = [[Crisis on Infinite Earths]]|Volume = |Issue = #12|Date = March 1986|Publisher = DC Comics}}</ref>

====After death====
[[Marv Wolfman]], writer for ''Crisis on Infinite Earths'', has repeatedly stated he left a loophole in the script allowing Barry Allen to be reintroduced, without a [[Retroactive continuity|retcon]], into DC Universe continuity. Wolfman first hinted at the loophole in his introduction to the original ''Crisis'' collected edition hardcover, and later then fully explained on his website.<ref>[http://www.marvwolfman.com/Q&A.html]  {{webarchive|url=https://web.archive.org/web/20060128175053/http://www.marvwolfman.com/Q%26A.html|date=January 28, 2006}}</ref> This loophole would allow a writer to pull Barry out of his desperate run to annihilate the anti-matter cannon. However, Barry would know he must someday finish his death run, and would become more determined to use his speed to help others.

In ''Deadman: Dead Again'', Barry is one of the heroes whose spirit [[Deadman (character)|Deadman]] helps to enter Heaven, and the ''[[Green Arrow]]'' storyline "Quiver" depicts Barry Allen in Heaven. His spirit seems to still be alive within the Speed Force, along with [[Max Mercury]] and other speedsters.[[Image:Quasar1.png|thumb|upright|Barry Allen as depicted in ''Quasar'', art by [[Mike Manley (artist)|Mike Manley]].]]In [[Quasar (comics)|''Quasar'']] by [[Marvel Comics]], released between December 1990 and May 1994, an amnesiac Barry Allen, misremembering his name as "Buried Alien" and the Speed Force as the "Hyperforce", and surprised to have "form" again, enters the [[Marvel Universe]] in the middle of the great race to be the "Fastest Man Alive" after the players had passed the first warp junction, where he is discovered by the Runner co-ordinating it and invited to participate in his race. Beating several other speedsters ([[Quicksilver (Marvel Comics)|Quicksilver]], [[Quasar (Wendell Vaughn)|Quasar]], [[Whizzer (Robert Frank)|The Whizzer]], [[Monica Rambeau|Captain Marvel]], [[Speed Demon (character)|Speed Demon]], [[Black Racer (Marvel Comics)|Black Racer]], [[Super Sabre (comics)|Super Sabre]], and [[Makkari (comics)|Makkari]]), he is declared to be the "fastest man alive", a title he believes feels "right", though he never recovers his memory during his time in the universe. He later adopts the alias "FastForward", before being returned to his original universe with Makkari's assistance.<ref>''Quasar'' #17 (December 1990)</ref><ref>''Quasar'' #58 (May 1994)</ref>

===Legacy===
Iris is pregnant and has two children who have super-speed powers, the Tornado Twins, who later meet the [[Legion of Super-Heroes]]. In the multiversal variant known as Earth-247, each of her children themselves have children with speed-based abilities. One, Jenni Ognats, grows up to become the Legionnaire [[XS (character)|XS]], while the other, [[Bart Allen]], is born with an accelerated metabolism that rapidly ages him, and is sent back to the 20th century where he is cured by Wally West. He remains there as the superhero Impulse under the tutelage of [[Max Mercury]], and later becomes the second Kid Flash as a member of the [[Teen Titans]]. [[One Year Later (comics)|One year]] after the events of ''[[Infinite Crisis]]'', Bart becomes the fourth Flash until he is killed by his clone [[Inertia (DC Comics)|Inertia]] and the [[Rogues (comics)|Rogues]].<ref>{{Cite comic|Writer = [[Marc Guggenheim|Guggenheim, Marc]]|Title = The Flash: The Fastest Man Alive|Volume = |Issue = #13|Date = August 2007|Publisher = DC Comics}}</ref> Wally then retakes the identity of the Flash.<ref>{{Cite comic|Writer = [[Mark Waid|Waid, Mark]]|Title = [[The Flash (comic book)#Volume 2 (1987–2006, 2007–2008)|All_Flash]]|Volume = |Issue = #1|Date = September 2007|Publisher = DC Comics}}</ref> Bart is later resurrected as Kid Flash by the [[Legion of Super-Heroes]] in the 31st century to combat [[Superboy-Prime]].<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Final Crisis: Legion of 3 Worlds]]|Volume = |Issue = #3|Date = April 2009|Publisher = DC Comics}}</ref>

===''JLA/Avengers''===
Barry Allen appears in issue 3 as the Flash in the JLA when the two realities start changing, along with Hal Jordan. When the two teams see their real futures, Barry witnesses his death during ''Crisis on Infinite Earths'' as the [[Grandmaster (Marvel Comics)|Grandmaster]] shows the heroes how reality should be but nevertheless resolves to help restore the timeline as it is not his place to play God. He talks with Hal Jordan over the similarity of their situation, stating that dying could not be so bad so long as they have left a legacy for others (Wally West and [[Green Lantern (Kyle Rayner)|Kyle Rayner]], in their cases) to fight for what they believe. He helps the team get into [[Krona (comics)|Krona]]'s base by using his running on a treadmill to pass the ship through the dimensional barrier. With the [[Wasp (character)|Wasp]], he is ordered by [[Captain America]] to find ways through Krona's defences, and alerts the group to a probably lethal force field. During the final battle, Barry saves [[Hawkeye (Clint Barton)|Hawkeye]] from being killed when the [[Absorbing Man]] breaks the ground beneath him, but both of them are blasted and apparently killed by [[Dreamslayer]]. At the end, it is revealed that Barry got the two of them out alive and at Captain America's suggestion they laid low. Because of this, Hawkeye is able to destroy Krona's machine with a TNT arrow while Barry distracts him and takes the twelve items of power. As a result, reality is restored, Barry disappears and Wally returns.

===Post-''Crisis'' appearances===
Wally West, wrecked by grief for the loss of his unborn twins at the hands of [[Reverse-Flash|Zoom]], regrets the public knowledge of his identity. Barry appears from somewhere in time—stating that he is from a period shortly before his death—counseling his nephew, and talking the [[Spectre (DC Comics character)|Spectre]] into granting his wish, erasing all public knowledge of Wally and Barry's identities as the Flash (Wally himself also loses his memory of his identity for a time). Barry then disappears, telling his nephew that he will come to his aid three times, on the three most difficult days of his life of which this is the first. In fact, when Zoom enlists the aid of the original Professor Zoom to make Wally relive the loss of his beloved twins, Barry is already there, trying to stop his "own" Reverse-Flash; Zoom apparently retrieved [[Eobard Thawne]] from the day that he attempted to kill Fiona Webb, with Barry following his nemesis. For the second time, he helps Wally undo the damage dealt by Zoom, also allowing Wally to save his twins, and returns to his proper time, dragging his Zoom with him and later breaking his enemy's neck.

====''Infinite Crisis''====
{{Main|Infinite Crisis}}
In the fourth issue of ''Infinite Crisis'', Barry Allen comes out from the Speed Force, along with [[Johnny Quick (Johnny Chambers)|Johnny Quick]] and [[Max Mercury]], to help his grandson Bart deal with [[Superboy-Prime]], taking the villainous teen with him in the Speed Force. Bart Allen appears wearing Barry Allen's costume in Tokyo near the end of ''Infinite Crisis'' #5 to tell the heroes that Superboy-Prime has escaped the Speed Force. Bart again reappears in ''Infinite Crisis'' #7 in Barry Allen's costume to combat Superboy-Prime once more.

In ''Flash: The Fastest Man Alive'' #6 (2006), it is told how Barry spent four years in an alternate [[Keystone City]] along with Mercury, Quick, and an alternate Jay Garrick, until he met Bart and Wally West, joining him after the battle against Superboy-Prime. After Superboy escapes, Barry suggests that someone has to absorb the whole Speed Force and cross the dimensional bridge back to Post-Crisis Earth. As Bart volunteers, Barry gives him his suit as a last gift, to keep the Force contained, and stays behind. Wally West did not go because of his wife and kids. Bart says he knows Barry would go if he could, but why Barry Allen could not make the journey himself is not stated.

===Flash's return===
[[Image:Barry Return.jpg|thumb|right|200px|Barry Allen returns to the DC Universe, fleeing from the [[Black Racer (DC Comics)|Black Racer]]. Art from ''[[Final Crisis]]'' #2 by [[J. G. Jones]].]]
Twenty three years after his death in ''Crisis on Infinite Earths'' #8, Barry Allen's essence makes a return to the present DC Universe proper in ''DC Universe'' #0, preceding his full-time return in the pages of ''[[Final Crisis]]''.

''DC Universe'' #0 features an unnamed narrator who initially associates himself with "everything". He begins to recall his past and association with [[Justice League]] members, particularly [[Hal Jordan]] and [[Superman]]. The lettering in which he speaks to the reader is yellow on backgrounds that are initially black. As the story moves forward, the background slowly begins turning red. In the final pages, the narration boxes feature a yellow lightning bolt. Over time, as he recalls friendships and connections with other people, his mind begins to narrow, remarking "I...know him.

Barry makes his corporeal return in ''Final Crisis'' #2. On the second to last page, [[Flash (Jay Garrick)|Jay Garrick]] and [[Wally West]] feel vibrations to which Jay remarks, "but, don't you recognize those vibrations? It can't be... Not after all these years... Not after all this time." On the final page, Barry Allen is seen in pursuit of the bullet which kills [[Orion (character)|Orion]], outrunning the Black Racer and shouting to Jay and Wally to "Run!"<ref>{{Cite comic|Writer = [[Grant Morrison|Morrison, Grant]]|Title = [[Final Crisis]]|Volume = |Issue = #2|Date = June 2008|Publisher = DC Comics}}</ref>

During ''Final Crisis'' #3, Jay Garrick speaks to Barry's wife, Iris, and tells her that her husband is alive. Meanwhile, Wally and Barry run a few weeks into the future. When they come to rest, Wally asks Barry if it is really him. Lamenting on Orion's death, which he was unable to stop, Barry wonders why he is now alive after being dead for so long. It is then that Barry and Wally are confronted by [[Wonder Woman]], [[Batwoman]], [[Catwoman]], and [[Giganta]], who have been transformed into the new [[Female Furies]] following the release of the [[Anti-Life Equation]].<ref>{{Cite comic|Writer = [[Grant Morrison|Morrison, Grant]]|Title = [[Final Crisis]]|Volume = |Issue = #3|Date = July 2008|Publisher = DC Comics}}</ref>

Despite the fact that this new version of the Female Furies is equipped with the ability to track down speedsters, perceived by [[Libra (DC Comics)|Libra]] and Darkseid as the only obstacle left between them and world domination, Barry's expertise allows him to overcome their foes and run through the ruined Earth.

Barry stops to see his wife Iris and save her from the slavery of the [[Anti-Life Equation]]. Seeing his wife again for the first time in years, Barry is overcome with emotion and gives his brainwashed wife a deep kiss. While kissing her, the Speed Force sparkles out of his body, enveloping Iris and freeing her from the Equation.

====''The Flash: Rebirth''====
{{Main|The Flash: Rebirth}}
In 2009, writer [[Geoff Johns]] and artist [[Ethan Van Sciver]] created ''[[The Flash: Rebirth]]'', a six-issue miniseries bringing Barry Allen back to a leading role in the DC Universe as the Flash, much in the same vein as ''[[Green Lantern: Rebirth]]''. When asked what Flashes would appear in the series, Johns and Van Sciver said, "All of them."

The series begins with the cities of Central and Keystone celebrating the return of "Central City's Flash", [[Wonder Woman]] having used her government contacts to create the story that Barry was in witness protection to account for his resurrection. Avoiding the parades, parties, and other celebrations of his return, Barry instead contemplates why he is alive again. A visit to the [[Flash Museum]] and from his friend [[Hal Jordan]] is not enough to put his mind at ease as he runs off as the Flash. "I can't be late," he says. When asked by Hal late for what, Flash replies, "For whatever the rest of the world needs me for."

It is then revealed that Flash's mother was murdered when he was a child, and his father was arrested for the crime (this is pointedly contrary to previous Flash stories, in which both his parents appear alive). Flash describes this as "the only one open case I left behind." Before he can contemplate this any further, the speedster villain [[Savitar (comics)|Savitar]] escapes the Speed Force through Flash. When Flash manages to put his hand on Savitar's shoulder, the villain screams in agony and crumbles into dust, not before telling Flash, "...You were the beginning, Allen...and you're the end." At that moment, [[Wally West]], West's children Iris and Jai, [[Jesse Chambers|Liberty Belle]], [[Flash (Jay Garrick)|Jay Garrick]], and [[Bart Allen|Kid Flash]] all experience painful convulsions and are engulfed in lightning.<ref name="TFR1">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #1|Date = April 2009|Publisher = DC Comics}}</ref>

Barry's conflict with the speed cult{{clarify|date=September 2011}} culminates in the death of their new leader who was attempting to avenge Savitar's death. It causes pain once again to all the speedsters, though Wally West manages to catch a glimpse of Allen directly afterwards, and sees him as the new [[Black Flash]].<ref name="TFR2">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #2|Date = May 2009|Publisher = DC Comics}}</ref> When he realizes that his presence could damage or kill other innocents, Barry flees back into the Speed Force, where he encounters old friends [[Johnny Quick (Johnny Chambers)|Johnny Quick]] and [[Max Mercury]]. Max attempts to tell Allen that his becoming the Black Flash is not his fault. When Max and Barry are pulled into another pocket of the Speed Force, the real culprit reveals himself: [[Professor Zoom]].<ref name="TFR3">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #3|Date = June 2009|Publisher = DC Comics}}</ref>

Zoom reveals his plan: after Barry briefly aided Kid Flash against Superboy-Prime during the ''[[Infinite Crisis]]'', Thawne was able to send a subliminal pulse into the Speed Force to draw back what was left of Barry's self-awareness. This led to the hero's reappearance during the ''[[Final Crisis]]''. Afterward, Zoom transformed himself into "a new kind of speedster" and created his negative Speed Force to contaminate Barry and the other heroic speedsters. Before Barry can fight any further, Zoom fades away. Wally enters the Speed Force to retrieve his uncle, and after venturing deeper into the Speed Force, Max reveals to Barry that it was Allen himself who created the Speed Force. Meanwhile, Wally manages to reach Barry and Max, and the three begin their escape. As the heroic speedsters are recharged with energy, Barry, Wally, Jay, Max, and Bart charge towards Zoom.<ref name="TFR4">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #4|Date = August 2009|Publisher = DC Comics}}</ref>

The seven speedsters (the 5 men plus Jesse Chambers and Iris West-Park) battle against Zoom, and despite being outnumbered, Zoom pulls Barry away. He reveals that everything horrible that happened to Barry, including the murder of Barry's mother, was caused by Zoom. Zoom then decides to destroy everything by killing Barry's wife, Iris, before they met.<ref name="TFR5">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #5|Date = November 2009|Publisher = DC Comics}}</ref>

Barry chases after Zoom, and is joined by Wally, who tells Barry to push as hard as he can to break the time barrier. They reach Thawne, and their lightnings turn Barry's past self into the Flash in the altered timeline (preserving Barry's destiny) as they are able to stop Zoom from killing Iris. As the two Flashes push Zoom back through time to the present, they see that the Justice League, the Justice Society, and the Outsiders have built a device specifically for Thawne. Barry tosses him in and activates the device, severing his connection to the negative Speed Force. The Flashes tie Zoom up to stop him from running. With the threat ended, everyone celebrates by welcoming Barry back and the speedsters in general. Later, Barry closes the case on his mother's death and opts to take all the other cold cases they had after his death. Barry spends some time with Iris before racing to Washington to celebrate his return with the Justice League, apologizing for being late.<ref name="TFR6">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash: Rebirth]]|Volume = |Issue = #6|Date = February 2010|Publisher = DC Comics}}</ref>

====''Blackest Night''====
{{Main|Blackest Night}}
[[Image:Blue Lantern Flash.jpg|thumb|right|200px|Barry Allen as a member of the [[Blue Lantern Corps]] during the ''[[Blackest Night]]'' event. Cover art to ''Blackest Night: The Flash'' #3 by [[Scott Kolins]].]]
Barry Allen is one of the main characters in Blackest Night alongside Hal Jordan. Allen appears alongside Jordan in the [[Free Comic Book Day]] issue ''Blackest Night'' #0 which acts as a prologue to the July company crossover.

At the grave of [[Batman|Bruce Wayne]] in [[Gotham City]], Hal and Barry reflect on Batman's death and how the hero community is avoiding linking Wayne and Batman.

This reflection turns to the pair looking at their deaths, comparing the sadness Barry's death engendered in others while Hal's death produced anger. Hal sums it up by telling Barry, "I died a sinner. You died a saint." The conversation moves on to the world becoming "more dangerous" after Barry's death and observing that the deaths of [[Aquaman|Arthur Curry]] and [[Martian Manhunter]] cost the [[Justice League]] its "heart and soul." As they leave the cemetery, Barry expresses hope that their dead comrades will be returned to them. He specifically cites Batman noting, "If there's an escape, you can bet Batman's already planning it."<ref name="BlackestNight0">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #0|Date = May 2009|Publisher = DC Comics}}</ref>

Barry also appears alongside Hal in the July issues of ''Green Lantern'' tying into the event. Recently, in a fight with [[Black Lantern Corps|Black Lantern]] [[J'onn J'onzz]], he found a mysterious black residue at Bruce Wayne's grave—a black form coagulating much like blood that started corrupting him by partly decaying his skin and muscle during the fight against his former friend, who is intent on killing both Hal and Barry, seeing how they both died and in the eyes of the Black Lanterns, must return to that state to keep the universe in balance.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = 1|Issue = 1|Date = July 2009|Publisher = DC Comics}}</ref><ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Green Lantern (comic book)|Green Lantern]]|Volume = 4|Issue = #44|Date = July 2009|Publisher = DC Comics}}</ref>

After fighting off the undead Martian and the subsequent Black Lanterns with Hal and the arriving [[Atom (Ray Palmer)|Atom]], [[Mera (character)|Mera]], [[Ronnie Raymond|Firestorm]], and two of the [[Indigo Tribe]] members, Barry, along with Wally and Bart, races across the globe to warn every superhero community across the planet.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #2|Date = August 2009|Publisher = DC Comics}}</ref> His message also inadvertently warns the Rogues. They all realize that their deceased members would come after them and decide to strike first at [[Iron Heights Penitentiary]], unaware that the undead Rogues are ready for them. While doing so, Barry meets a Black Lantern version of Professor Zoom for a brief battle. Barry decides to go to [[Gorilla City]] to seek aid from its ruler [[Solovar]], unaware the gorilla leader had been killed years before. Finding the city attacked, Barry assumed [[Gorilla Grodd|Grodd]] had struck only to be horrified to learn Solovar was now a Black Lantern. Their fight was shortened by Barry racing to [[Coast City]].<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night|Blackest Night: Flash]]|Volume = |Issue = #1|Date = December 2009|Publisher = DC Comics}}</ref>

He stops at the city's memorial, where he witnesses the arrival of the Black Lanterns' demonic lord, [[Nekron]], and his disciples [[Scar (comics)|Scar]] and [[Black Hand (character)|Black Hand]].<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #4|Date = October 2009|Publisher = DC Comics}}</ref> The Justice League, the [[Teen Titans|Titans]], Wally, and Bart arrive to aid Barry to take a stand against Nekron. Nekron reveals that all the resurrected heroes are tied to him because he allowed them to rise again. As such they belong to him. Nekron then used a series of black rings to turn Superman, Wonder Woman, Troia, Green Arrow, Bart, and several other resurrected heroes into Black Lanterns. Barry and Hal find themselves being targeted by black rings and are forced to flee or risk joining the others as Black Lanterns.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #5|Date = November 2009|Publisher = DC Comics}}</ref>
Barry saves himself and Hal through time travel two seconds forward, leaving the rings with no present targets. As Barry and Hal rejoin the heroes against Nekron and his army, [[Ganthet]], one of the [[Guardians of the Universe]] and a leader of the [[Blue Lantern Corps]], summons a blue power ring and Barry is chosen as a Blue Lantern so he would be more effective during the battle.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #6|Date = January 2010|Publisher = DC Comics}}</ref>

After being chosen as a Blue Lantern, Barry joins forces with the veteran Blue Corps member [[Saint Walker]] to continue battling the Black Lanterns alongside the understanding of the potentials and limitations of his new power ring. During the battle, Barry is forced to fight his own grandson, who his ring detects is still alive but would die if not free from the black ring soon. Barry is shown to be skilled with his ring in creating energy constructs based on his imagination and the ability to fly (possibly because of the understanding with Hal's ring), as he can create images of Bart as Impulse and Kid Flash against him to make him feel again. Barry's plan almost works as Bart reacts to the images of his past, and the constructs attempt to take the black ring from him, but later is interrupted by the Black Lantern Professor Zoom and Solovar. Wally and Walker later join Barry to fight against them.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night|Blackest Night: Flash]]|Volume = |Issue = #2|Date = February 2010|Publisher = DC Comics}}</ref> Barry and Bart temporarily joined the [[White Lantern Corps]] near the end of ''Blackest Night''.<ref>{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[Blackest Night]]|Volume = |Issue = #8|Date = March 2010|Publisher = DC Comics}}</ref>

===''The Flash'' Volume 3===
{{Main|The Flash (comic book)#Volume 3 (2010–2011)|l1=The Flash (comic book)#Volume 3 (2010–2011)}}
The new ''Flash'' series begins after the completion of ''[[Blackest Night]]'' and the beginning of ''[[Brightest Day]]''. After the events of ''[[The Flash: Rebirth]]'', Barry Allen is reintegrating himself into life in [[Central City (DC Comics)|Central City]]. Under the cover of having been in [[witness protection]], Allen returns to the Central City Police Department's crime lab and returns to the streets as the Flash. While readjusting to life as the Flash, a man appears out of thin air in the costume of Flash rogue the [[Mirror Master]], and promptly dies on the street.

When Barry arrives on the scene to investigate, he sees the man is neither original Mirror Master Sam Scudder, or the current Mirror Master, Evan McCulloch. Hearing of another portal appearing, Barry transforms into the Flash and runs to investigate. When he arrives, a group of people in costumes similar to the Rogues, called ''[[Rogues (comics)#The Renegades|The Renegades]]'' appear and tell Barry that they are from the 25th century, and that he is under arrest for murdering the "Mirror Monarch". Barry tells the crew that he has not killed anyone, to which their leader, "Commander Cold", tells him, "Not yet. But you will."<ref name="vol3no1">{{Cite comic|Writer = [[Geoff Johns|Johns, Geoff]]|Title = [[The Flash (comic book)|The Flash]]|Volume = 3|Issue = #1|Date = April 2010|Publisher = DC Comics}}</ref>

After a brief struggle, where Weather Warlock's time disc was damaged, the Renegades were forced back to the 25th century, which also caused the destruction of an apartment building due to their uncontrolled jump back. Barry saves everyone in the building, even rebuilding the building in minutes, and goes on to search for the true killer of Mirror Monarch. He is attacked again by the Renegades, but only before Captain Boomerang shows up, now wielding explosive energy boomerangs. Boomerang fights both the Flash and the Renegades, and a confused Top (one of the Renegades from the 25th century) questions his teammates on whether or not Barry Allen is the man they are looking for, pointing out that in their timeline, Boomerang never showed up.

The Renegades finally corner Captain Boomerang when the Rogues arrive with a giant mirror left by the previous Mirror Master that says "In Case The Flash Returns Break Glass". An all out brawl ensues as the Rogues battle the Renegades. Meanwhile, Flash is confronted by Top who warns him that the reason he will kill Mirror Monarch is because of Iris's death, which he claims will be caused when the giant mirror breaks, releasing the Mirror Lords. Top tells Barry that one of the Mirror Lords will possess Iris and take her away from him. Barry races to stop the mirror from breaking, with Top at his side. However, when the White Lantern entity reaches out to Captain Boomerang, telling him to "Throw the Boomerang", Boomerang responds by throwing dozens of boomerangs in every direction. One of them hits the glass and it begins to break. Top tells Flash to stop the Mirror Lords, while he goes and protects Iris. Flash questions does not make sense, but Top throws him into the mirror and flees.

In the mirror, Flash is exposed to strange visions of his mother. Outside, the Rogue Mirror Master tells the others that the mirror is actually a slow acting poison and they flee. Barry escapes the mirror confused and asks, "Where are the Mirror Lords?" He is then arrested by the Renegades, who realize that this was all a setup by Top to frame the Flash for his own personal gains. Barry is transported to a 25th-century court, while Top confronts Iris.

The story concludes with Barry escaping the 25th century court and going after Top. Top reveals that the reason for all of his crimes is because Barry reopened a previously closed case. Barry felt that the person convicted was actually innocent. The person who is actually guilty of the crime is one of Top's ancestors. Top reveals that they do not allow anyone in the Renegades who has any ancestors with a criminal record. The Flash is able to beat Top, and convict the right man for murder, letting go the innocent man who was sent to prison. Afterward, the 25th century court and the Renegades go over the facts, realizing that the Flash was right and that their entire record of history is wrong. This alludes to the upcoming Flash event, ''[[Flash: Flashpoint|Flashpoint]]''. Meanwhile, a man on a Speed Force-powered motorcycle (later revealed to be a Speed Force police officer under the name of Hot Pursuit)<ref>''The Flash'' (vol. 3) #8 (November 2010)</ref> moves through the desert and says that if Barry does not find the flashpoint, it will destroy the world. As he continues through the desert, Speed Force lightning strikes in the distance.

In a ''Green Lantern'' storyline, Barry becomes the latest host for the embodiment of fear, [[Parallax (character)|Parallax]], after he joins Hal Jordan's quest of locating all of the entities who each represent aspects of the power of the emotional spectrum. Barry was susceptible to the entity's attacks due to his fear for Jordan's safety.<ref>''Green Lantern'' vol. 4 #59 (November 2010)</ref> Barry is freed after the embodiment of compassion, Proselyte, helps him remember his capability for benevolence over his fear.

====''Flashpoint''====
{{Main|Flashpoint (comics)}}
As the story begins, Barry Allen wakes up in his office and discovers that his mother is alive, there is no trace of [[Superman]], [[Wonder Woman]] and [[Aquaman]] leading their respective nations in a war, his wife [[Iris West]] is unmarried, and himself currently powerless. Barry seeks the aid of [[Batman]], driving to Gotham City and entering a run-down [[Wayne Manor]]. He explores what turns out to be a small Batcave until he is attacked by Batman. Barry tries to explain who he is by saying he knows Batman is Bruce Wayne, only to find that in this reality, Batman is [[Thomas Wayne]].<ref>''Flashpoint'' #1 (May 2011)</ref> While Barry is being beat up by Batman, he explains about his secret identity as the Flash and his relation to Bruce Wayne. Barry's memories spontaneously change and he realizes that the world of Flashpoint is not an alternate dimension, but his own. Barry uses his ring, which he uses to contain his Flash outfit, but the ring instead ejects [[Professor Zoom]]'s costume. Barry tells Batman that Zoom is taunting him with it. Barry explains that both he and Zoom have the ability to alter time, leading Batman to ask him about how Bruce was to have lived in his place and if he can really change the world. Barry states that he needs his speed first. Later, Barry and Batman create an electric chair-like device to try and recreate the accident that gave him his speed; however, the first attempt meets with failure, leaving Barry severely burned.<ref>''Flashpoint'' #2 (June 2011)</ref>

Barry awakes on an operating table in the Batcave and is covered in bandages and third degree burns. Despite Thomas' advice, Barry sits back down in the electric chair device. When lightning strikes a second time, Barry's super-speed returns, and he then saves the Batman from being impaled on a fence. Barry's injuries are healing rapidly due to his speed-enhanced regeneration. He also makes a new copy of his Flash costume. The Flash researches the incarnations of heroes of the DC timeline, believing that Zoom deliberately changed their lives to prevent the Flash from creating a Justice League, and learns of a rocket that crashed into Metropolis which carried the infant Superman, who instead of being raised in Kansas was taken in by the government. They then contact [[Cyborg (DC Comics)|Cyborg]] for his help in sneaking into the government bunker of "Project: Superman" that is 'raising' Superman after his rocket destroyed Metropolis upon its arrival, only to be disappointed at Superman's frail appearance. They head towards Project: Superman's underground base via the sewer. The group comes across a giant vault door bearing the Superman logo. After they open the door, the three see a pale, weakened Kal-El. Despite his appearance, Barry says that no matter what, Superman will always be a good person. When the arrival of guards forces them to escape, Superman's powers begin to manifest and he flies off leaving them at the hands of the guards.<ref>''Flashpoint'' #3 (July 2011)</ref>

While they fend off the guards, they are rescued by Element Woman. Barry's memories begin to change much more drastically, altering his past. He states that he is running out of time and soon he will not be able to restore the timeline to normal. After Barry is recovering, he asks the heroes to stop the [[Atlantis (Aquaman)|Atlantean]]/[[Amazons (DC Comics)|Amazon]] war from creating more casualties, although the heroes are not willing to unless Batman wants to join them. Cyborg explains to him that they believe Batman was invincible. However, Barry convinces him that no one is invincible; the [[Marvel Family]] and Batman agree to join him. The heroes arrive at New Themyscira to stop the Atlantean/Amazon war, and appear to be winning until [[Enchantress (DC Comics)|Enchantress]] reveals herself as the Amazon spy and uses her magic to separate the Marvel Family and restore them to their mortal forms. Penthesilea kills [[Shazam (DC Comics)|Billy Batson]] just as Professor Zoom reveals himself to Barry.<ref>''Flashpoint'' #4 (August 2011)</ref> Professor Zoom reveals to him that the "Flashpoint" timeline was created by Barry himself, after he traveled back in time to stop Zoom from killing his mother, but the timeline diverted into the near-apocalyptic world they find themselves in. He continues to taunt Barry with this knowledge, but is suddenly stabbed in the back by Batman wielding an Amazonian sword. Before Barry returns the timeline to normal, Batman thanks him for all he has done and gives him a letter addressed to his son. After this, Barry bids a farewell to his mother, knowing he must travel back in time to stop his younger self from altering time. Through the fusions of the time stream, Barry seemingly hears [[Pandora (DC Comics)|a voice]] explaining that the three timelines and worlds, need to become one again and would need his help to do this. After the ordeals, he visits the real Bruce Wayne and gives him the letter from his alternate father. Bruce is grateful to Barry of informing him of the events of the "Flashpoint" before the timeline was apparently returned to normal.<ref name="fp5">''Flashpoint'' #5 (August 2011)</ref>

===The New 52===
DC Comics relaunched ''The Flash'' with issue #1 in September 2011, with writing and art chores handled by [[Francis Manapul]] and Brian Buccellato as part of DC's company-wide title relaunch, ''[[The New 52]]''.<ref>{{cite web|url=http://www.comicbookresources.com/?page=article&id=32768 |title=DC Comics Solicitations for September, 2011 |work=Comic Book Resources |publisher=[[Comic Book Resources]] |date=June 13, 2011 |url-status=live |archive-url=https://web.archive.org/web/20130928144827/http://www.comicbookresources.com/?page=article&id=32768 |archive-date=September 28, 2013 }}</ref><ref>{{cite web|url=http://speedforce.org/2011/06/flash-reboot/ |title=Flash Reboot Creative Team: Francis Manapul and Brian Buccellato |publisher=SpeedForceOrg |date=June 2, 2011 |url-status=live |archive-url=https://web.archive.org/web/20130817004046/http://speedforce.org/2011/06/flash-reboot/ |archive-date=August 17, 2013 }}</ref> As with all of the books associated with the DC relaunch, Barry Allen appears to be about five years younger than the previous incarnation of the character. He gains his powers after getting frustrated and throwing a small machine at the window of his lab. The machine breaks through the window, leaving a hole big enough for a bolt of lightning to charge through the hole and strike him.

In the second issue of the new ''[[Justice League]]'' title (the first released comic series of the New 52 initiative and "opening shot" of the new DC Universe), Flash is called to assist [[Hal Jordan|Green Lantern]] and [[Batman]] in wrangling an out-of-control [[Superman]], and later assists with the pursuit of an alien, revealed to be an agent of [[Darkseid]].<ref>{{cite comic| writer= Johns, Geoff| penciller= [[Jim Lee|Lee, Jim]]| inker= Williams, Scott| story= Justice League Part Two| title= Justice League| volume= 2| issue= #2| date= December 2011}}</ref> In this new continuity, Barry's marriage to Iris West never took place, and he is instead in a relationship with longtime co-worker [[Patty Spivot]]. In this new series, the Flash draws deeper into the Speed Force, enhancing his mental abilities while still trying to fully grasp his powers, which he does not yet exert total control over.

As revealed in issue #0 of the current series, Barry Allen's father was placed in prison for the murder of his mother. The murder occurred shortly after Barry returned victorious from a school spelling bee, and Barry placed the trophy he won on his mother's grave in her memory. While the evidence seems to indicate his father's guilt, Barry prioritizes proving his father's innocence.

Barry is also part of the main cast of the relaunched ''Justice League'' series, making his debut in the series' second issue. Following Convergence, Barry has a new suit in issue #41, which has a darker shade and features more streaks.

===DC Rebirth===

During ''DC Rebirth'', Barry is no longer the only Flash. It is revealed that [[Wally West]] has been lost in the Speed Force for ten years, realizing during this time that Barry is not responsible for changing the timeline after the ''[[Flashpoint (comics)|Flashpoint]]'' crisis, the [[Doctor Manhattan|unknown entity]] used Barry's time traveling as an opportunity to fundamentally alter reality. The fallout of the recent Darkseid War allowed Wally to try and reach out to his former friends in the hopes of either returning or warning them of the truth, but each attempt caused him to fall further into the Speed Force. After realizing not even Linda (his traditional "lightning rod") could remember him, Wally sank into desolation and chose to appear before Barry one last time to thank him for the life he had given him. Just before Wally disappeared, Barry remembered him and dragged him free of the Speed Force. Following a tearful reunion, Wally gave Barry his warning of the true source of the universal change and the dangers to come. Because of Wally, Barry is now aware that the timeline is not reset correctly after Flashpoint and thus another alternate timeline. However, he still cannot remember his pre-Flashpoint life, such as people like Jay Garrick, his long-last marriage with Iris, and the details of his feuds with the Reverse-Flash / Eobard Thawne (who now remembers their pre-Flashpoint history), and remembers Wally from their new DC Rebirth timeline history. Despite being informed by Wally that another party is responsible, Barry remains in guilt over his mistakes, and seeks to find and stop them in hopes of making amends.<ref>''DC Universe: Rebirth'' one-shot (May 2016)</ref> Although the two decide to keep Wally's return secret from Iris based on Wally's own experience with Linda, Barry encourages him to return to the Titans, but also recommends that he don a new costume to reflect that he is the Flash rather than 'Kid Flash'. While Wally considers his options, Barry visits Batman to discuss the new evidence of some outside force attacking them, musing on how personal this assault appears, but despite the potential danger, Batman and Barry agree to keep their investigation to themselves until they know what they are up against.<ref>''The Flash: Rebirth'' one-shot (June 2016)</ref> Later, when Eobard Thawne attacks Iris and [[Ace West|Wallace]], Iris has glimpses of her pre-Flashpoint life with Barry and learns his secrets as the Flash in the process. Barry then learned of their marriage in the other timeline as well. Knowing from Thawne that her entire life has been drastically altered and that Barry is indirectly responsible for it as the result of his time-traveling actions, Iris now distrusts Barry.<ref>''The Flash'' vol. 5 #24 (August 2017)</ref> To make matters worse for Barry, while he is entering the Negative Speed Force, he becomes the Negative Flash which is more lethal than the original, and mostly dangerous to control.

After getting rid of the Negative Speed Force, he investigates the death of Turbine, but thanks to Godspeed's help, he discovers that [[Captain Cold]] was the one who killed him because he seeks redemption. He visits Wally after defeating the Top, and he discusses him telling Iris that he is alive. While he is rekindling his relationship with Iris, the city is being attacked by Gorilla Grodd and his organization the [[Black Hole (DC Comics)|Black Hole]], with Grodd mind-controlling [[Fast Track (comics)|Meena Dhawan]] to be the group's Negative Flash.

After defeating Grodd and getting Wally to meet Iris for the first time, they encounter the Renegades. The Renegades take the Flashes and Iris back to the 25th century to get answers about why Iris killed Eobard Thawne, only to discover that [[Hunter Zolomon]] has been manipulating everyone in a plot to bring conflict between Barry and Wally for the fate of the Speed Force. After Wally defeated Hunter, Barry places him under watch at the Sanctuary while he is moving in with his girlfriend Iris at her place after Wallace angrily left them. Barry begins searching for the other forces. Hunter Zolomon arrives, powered with the Sage and Strength Force, claiming to be the "one true Flash". He defeats Barry and takes Steadfast away to claim the Still Force for himself. Black Flash also arrives and warns the defeated Barry not to interfere in his mission. Zolomon tortures Steadfast to give him the Still Force, but Steadfast resists. Finally, a revived Barry tracks down Zolomon and tries to rescue Steadfast, but Zolomon's power over other forces proves too much for him. Steadfast tries to use the Still Force to stop both the speedsters, but the plan backfires as Zolomon approaches and takes the Still Force. With the control of all four forces, Zolomon enters the Forever Force taking forces such as the Sage Force and the Strength Force after the Force Barrier's broken; he ends up discovering about the four forces conflicting for the control of the Forever Force. He manages to track down the Still Force user Steadfast and the Strength Force user [[Fuerza (comics)|Fuerza]] to bring them to his team after the Black Flash starts hunting the other force users to prevent them from using their powers as the other forces weaken and deplete the Speed Force. However, the Sage Force user Psych refuses to join Barry's team only to be later tracked down and killed by the Black Flash. To safeguard the other force users Barry sends Fuerza and Commander Cold to the Strength Force and stays behind with Steadfast.

Barry meets Hunter Zolomon again, and watches as Hunter sacrifices himself to heal the Force Barriers.<ref>{{Cite web |date=2019-10-28 |title=The Flash #81 Review — Major Spoilers — Comic Book Reviews, News, Previews, and Podcasts |url=https://majorspoilers.com/2019/10/28/the-flash-81-review/ |access-date=2024-06-23 |language=en-US}}</ref> Barry Allen is forced to recruit [[Eobard Thawne]] and [[Godspeed (character)|Godspeed]] in his help against a villain name Paradox by traveling back in time to the place where Eobard murdered his mother.<ref name="Arvedon">{{Cite web |last=Arvedon |first=Jon |date=2020-05-05 |title=Explore The Many Deaths of Eobard Thawne in The Flash #753 Preview |url=https://www.cbr.com/flash-753-eobard-thawne-deaths-preview/ |access-date=2024-06-23 |website=CBR |language=en}}</ref> Eobard and Godspeed help Barry defeat Paradox, but Eobard kills Godspeed and escapes.<ref name="Arvedon" /> Eobard Thawne takes over Barry's body, but Barry manages to free himself with the help of [[Jesse Chambers]] and [[Max Mercury]] while meeting Inertia (a clone of [[Bart Allen]]) in the Speed Force for the first time.<ref>{{Cite web |last=Rutzick |first=Sam |date=2020-08-25 |title='The Flash' #760 review • AIPT |url=https://aiptcomics.com/2020/08/25/the-flash-760-review/ |access-date=2024-06-23 |website=aiptcomics.com |language=en-us}}</ref>

=== Dawn of DC ===
Barry had planned to propose to Iris, but an attack from an alien species kills her. He helps Wally and the fellow speedsters defeat the alien army and undo Iris' death, and she accepts his proposal.<ref>{{Cite web |last=Sawan |first=Amer |date=2023-03-10 |title=The Flash Claims He Can Undo the One-Minute War - But How? |url=https://www.cbr.com/the-flash-barry-allen-one-minute-war-undo-dc/ |access-date=2024-07-04 |website=CBR |language=en}}</ref> In "[[The New Golden Age]]", Flash was among those who attended a party held by the Flash family.<ref>''Jay Garrick: The Flash'' #6</ref> In "[[Absolute Power (comics)|Absolute Power]]", Barry is the only member of the Flash family to still have a connection to the Speed Force after the connections of the other speedsters are severed by [[Amanda Waller]]. After Waller's Amazo task force is defeated, Barry's powers are taken and the rest of the speedsters lose access to the multiverse.<ref>''Absolute Power'' #4 (December 2024)</ref>

==Powers and abilities==
As with all Speed Force users/conduits Barry's main power is superhuman speed. Barry is generally considered to be the second fastest non-omnipotent character in the DC Universe after his successor and nephew Wally West. Barry is capable of running many magnitudes faster than light speed. Barry has been calculated as going as fast as 13 million times the speed of light and has feats that are faster. He has outrun numerous incredibly fast characters including Reverse Flash, Superman, Supergirl, and the Black Racer, the "Grim Reaper" of speedsters.

Barry's speed has numerous secondary applications. He can use it to generate cyclones by spinning his arms quickly. By vibrating the molecules in his body at hypersonic frequencies, Barry can turn invisible or phase through solid matter. Barry can also manipulate the electrical Speed Force energy he generates. He can channel the energy into arcs of lightning, as well as use the electricity to manipulate magnetism on a minor level. He has also used the lightning to create blinding amounts of light. By interlocking his lightning with that of another speedster, Barry can short circuit their connection to the Speed Force. Barry is also immune to telepathic attacks and control as he can shift his thoughts at a speed faster than normal thought via the Speed Force. Through "speed-reading", he can absorb large amounts of information into his [[short-term memory]], which remain in his mind just long enough for him to make use of it. Using this technique, Barry was able to learn enough about building work to rebuild a destroyed apartment building.<ref>''The Flash'' (vol. 3) #2 (May 2010)</ref> The Speed Force also supplies Barry with a protective aura that shields him and people he carries from friction and kinetic impacts, as well as grants him superhuman durability. Other aspects of Barry's powers include an enhanced [[metabolism]], which grants him a regenerative healing factor. In the New 52, Barry learned that his body is using the Speed Force to its full extent but his brain was not. With the help of Dr. Elias he was able to learn how to use the Speed Force to process more information, and make even quicker decisions, to the point where he feels like he can see everything before it happens.<ref>''The Flash'' (vol. 4) #2 (December 2011)</ref> Barry also developed the ability to speed up the flow of time around him, which he used to negate the powers of Zoom, who was able to slow down time. In terms of DC's internal lexicon, Barry is classified as a metahuman: a human being who possesses extranormal abilities either through birth or as the result of some external event.<ref>''Superman'' (vol. 3) #7 (2012)</ref><ref>''Voodoo'' (vol. 2) #7 (2012)</ref>

As of 2024, Barry no longer has any powers due to the events of ''Absolute Power'', where he sacrificed his connection to the Speed Force.

==Rogues gallery==
{{Main|Rogues (comics)}}
Some of the Flash's enemies formed a loose association and referred to themselves as the [[Rogues (comics)|Rogues]], disdaining the use of the term "[[supervillain]]" or "super-criminal". These criminals typically have unusually modest goals for their power level (robbery or other petty crimes), and each have adopted a specific theme in their equipment and methods.
