'''Captain Atom''' is the name of several [[superhero]]es appearing in [[American comic book]]s, initially owned by [[Charlton Comics]] before being acquired in the 1980s by [[DC Comics]].<ref name="Guide">{{cite book |last1=Cowsill |first1=Alan |last2=Irvine |first2=Alex |last3=Korte |first3=Steve |last4=Manning |first4=Matt |last5=Wiacek |first5=Win |last6=Wilson |first6=Sven |title=The DC Comics Encyclopedia: The Definitive Guide to the Characters of the DC Universe |date=2016 |publisher=DK Publishing |isbn=978-1-4654-5357-0 |page=59}}</ref> All possess some form of energy-manipulating abilities, usually relating to [[nuclear fission]] and [[atomic power]].

Originally created by [[Joe Gill]] and [[Steve Ditko]] during the [[Silver Age of Comic Books]] to occupy a [[Superman]]-like role in Charlton Comics' line-up, the character became part of the [[DC Universe]] in 1985 after DC's purchase of Charlton in 1983. The character's similarities to [[Superman]] led to DC making numerous attempts to find a distinctive niche for the character within its own stories. As a result, he has played varied roles in the [[DC Universe]], many short-lived, including a period as the supervillain [[Monarch (comics)|Monarch]] and the attempted reboot series ''[[Breach (character)|Breach]]''. Notably, DC's decision not to give [[Alan Moore]] permission to use the character in his critically and commercially successful ''[[Watchmen]]'' (1986) series led to the creation of the popular character [[Doctor Manhattan]]. Modern depictions of Captain Atom have instead emphasised, rather than de-emphasise, his similarities to Manhattan. 

Captain Atom has appeared in several animated television and film adaptations of Justice League and other DC storylines since the mid-2000s. [[Chris Cox (voice actor)|Chris Cox]], [[Michael T. Weiss]], and [[Brian Bloom]], among others, have voiced the character in animation. 

==Publication history==
Captain Atom was created by writer Joe Gill and artist/co-writer Steve Ditko, and first appeared in ''[[Space Adventures (comics)|Space Adventures]]'' #33 (March 1960).<ref>{{cite book|last=McAvennie|first= Michael|editor-last = Dolan|editor-first = Hannah|chapter= 1960s|title = DC Comics Year By Year A Visual Chronicle|publisher=[[Dorling Kindersley]] |year=2010 |isbn= 978-0-7566-6742-9 |page= 99 |quote = Captain Atom was born in a tale by artist Steve Ditko and writer Joe Gill.}}</ref> Captain Atom was initially created for [[Charlton Comics]], but was later acquired by [[DC Comics]] and revised for DC's post-''[[Crisis on Infinite Earths|Crisis]]'' [[Continuity (fiction)|continuity]].<ref>{{cite web |last1=Markstein |first1=Don |title=Captain Atom |url=http://www.toonopedia.com/capatom1.htm |website=Don Markstein's Toonopedia |access-date=2 April 2020}}</ref> In 2011, DC Comics relaunched its superhero comics and rewrote the histories of some characters from scratch, including Captain Atom, giving him a new origin, appearance and slightly altered powers. Captain Atom was the inspiration for [[Doctor Manhattan]], who was featured in the miniseries ''[[Watchmen]]'', which would be connected to the DC Universe in the miniseries [[Doomsday Clock (comics)|''Doomsday Clock'']].<ref name="Characters2">[https://www.twomorrows.com/comicbookartist/articles/09moore.html "Alan Moore Interview – Comic Book Artist #9"]  —  An interview with Alan Moore.

Throughout the years, the character has been featured in several moderate-to-short-lived eponymous series, and has been a member of several different versions of DC's flagship superhero team, the [[Justice League]]. In all incarnations, the character initially served for the [[United States armed forces|military]]. In the Charlton Comics continuity, he was a scientist named '''Allen Adam''' and gained his abilities by accident when he was seemingly "atomized" and then reformed himself as an atomic-powered being. In both DC Comics incarnations, he is an [[United States Air Force|Air Force]] pilot named '''Nathaniel Adam''', who was a test subject in a scientific experiment who seemingly disintegrated in the process, only to reappear later as the super-powered Captain Atom.<ref name="dc-ency">{{Cite book|last = Beatty|first = Scott|author-link = Scott Beatty|contribution = Captain Atom|editor-last = Dougall|editor-first = Alastair|title = The DC Comics Encyclopedia|page = 67|publisher = [[Dorling Kindersley]]|place = New York|year = 2008|isbn = 978-0-7566-4119-1|oclc = 213309017}}</ref> Over the years, DC has attempted to reinvent the character several times. For a period, the character assumed the mantle of the supervillain [[Monarch (comics)|Monarch]], and in 2005 DC attempted to retell the Captain Atom story with an entirely new character, [[Breach (character)|Breach]], who was subsequently discarded. In the new continuity following DC's [[The New 52|2011 relaunch]], Captain Atom has never been a member of the Justice League and the team views him with distrust; his character origin and abilities were also revised.

==Fictional character biography==
===Charlton Comics (Silver Age)===
[[file:Cover_of_Space_Adventures_no._33.jpg|left|thumb|''[[Space Adventures]]'' #33 (March 1960), Captain Atom's debut, cover art by [[Steve Ditko]].]]

The Charlton Comics version of Captain Atom was '''Allen Adam''', a rocket technician who gains powers after his special experimental rocket explodes.<ref>{{cite book |last1=Cowsill |first1=Alan |last2=Irvine |first2=Alex |last3=Manning |first3=Matthew K. |last4=McAvennie |first4=Michael |last5=Wallace |first5=Daniel |title=DC Comics Year By Year: A Visual Chronicle |date=2010 |publisher=DK Publishing |isbn=978-0-7566-6742-9 |page=93}}</ref>

Captain Atom was first published in a series of short stories in the [[anthology]] series ''[[Space Adventures (comics)|Space Adventures]]'' #33–40 (March 1960 – June 1961) and #42 (October 1961). Charlton began reprinting his short adventures in the anthology ''[[Strange Suspense Stories]]'' beginning with issue #75 (June 1965), renaming the title ''Captain Atom'' with issue #78 (December 1965) and giving the hero full-length stories and [[supervillain]] antagonists such as Dr. Spectro (previous stories involved [[Cold War]] anti-Communist missions or dealing with aliens). Captain Atom later teamed with the superhero [[Nightshade (DC Comics)|Nightshade]], with whom he shared a mutual attraction. The superhero [[Blue Beetle]] starred in the initial back-up feature, later replaced by a Nightshade back-up series.

While primarily referred to as Allen Adam in stories, the [[fanzine]] title ''[[Charlton Bullseye (fanzine)|Charlton Bullseye]]'', published in cooperation with Charlton Comics, gives the character's name as '''N. Christopher Adam''', which would later be used as the civilian identity for the Post-''Crisis'' version of the character.<ref>{{cite comic|title = Charlton Bullseye |issue = 1 | publisher = CPL/GANG Publications| date = January–February 1975}}</ref> A later issue of a showcase comic book series published by Charlton also by the name of ''[[Charlton Bullseye (comics)|Charlton Bullseye]]'' gave the character's name as '''John Adam'''.<ref>{{cite comic | title    = Charlton Bullseye | issue    = 7 | publisher= Charlton Comics | date     = May 1982}}</ref>

DC Comics acquired Captain Atom, among other characters, following the bankruptcy of Charlton Comics. In ''[[Crisis on Infinite Earths]]'', the Charlton characters are revealed to originate from Earth-Four and are integrated into DC's continuity.

===DC Comics (Post-''Crisis'')===
A new Post-''Crisis'' version of the character was introduced in March 1987 with the launch of a monthly comic, written by [[Cary Bates]] and [[Greg Weisman]] and drawn by [[Pat Broderick]].<ref>Manning, Matthew K. "1980s" in Dolan, p. 229: "March [1987] debuted the new Captain Atom in his first DC series, by writer Cary Bates and penciler Pat Broderick".</ref>

This modern captain's name is established as '''Nathaniel Christopher Adam''', a [[United States Air Force]] officer and [[Vietnam War]] veteran. Adam is framed for a crime and experimented on to avoid execution and receive a pardon. He gains metallic skin and vast nuclear powers, but is transported decades into the future and presumed dead.<ref name="dc-ency"/><ref>{{Cite comic|Writer = [[Cary Bates|Bates, Cary]]|Penciller = [[Pat Broderick|Broderick, Pat]]|Inker = Smith, Bob|Story = A Matter of Choice!|Title = Captain Atom|Volume = 2|Issue = #11|date = January 1988|Publisher = DC Comics|Page =|Panel =|ID =}}</ref>

After Adam resurfaces, [[General Wade Eiling]] blackmails him into serving the government as the superhero Captain Atom. Atom separates from the government, joins the Justice League, and briefly marries [[Plastique (character)|Plastique]].<ref>''Captain Atom'' vol. 3, #1 (1983)</ref>

Captain Atom was intended to be the villain [[Monarch (comics)|Monarch]] in the ''[[Armageddon 2001]]'' event. However, after this information was leaked, DC changed Monarch's identity to Hank Hall last-minute.<ref>''Zero Hour: Crisis in Time''</ref><ref name="dc-extr">{{Cite book|last = Beatty|first = Scott|author-link = Scott Beatty|contribution = Extreme Justice|editor-last = Dougall| editor-first = Alastair|title = The DC Comics Encyclopedia|page = 117|publisher = [[Dorling Kindersley]]|place = New York|year = 2008| isbn = 978-0-7566-4119-1|oclc = 213309017}}</ref>

In the ''[[Superman/Batman]]'' story arc "Public Enemies", Captain Atom is seemingly killed while stopping a [[kryptonite]] meteor. He is transported to the [[WildStorm]] universe and presumed dead.

The end of ''Armageddon'' has him reappear in the devastated [[Blüdhaven]]. [[One Year Later (comics)|A year later]], Captain Atom is revealed to be contained inside Blüdhaven and used to administer radiation treatments to [[metahuman]]s. He later escapes and kills [[Major Force]].<ref>''Ion'' #10</ref>

===DC All In===
In ''[[Absolute Power (comics)|Absolute Power]]'', Captain Atom loses his powers to [[Amanda Waller]]'s [[Amazo]] army. [[Atom (Ray Palmer)]] and [[Atom (Ryan Choi)]] use him to test a device that can retrieve powers and restore them to the correct superhero. This leads to Adam's powers returning at full strength, along with those of other "Atom Project" subjects. In the series ''[[Jenny Sparks]]'' (2024), the titular character works with the Justice League in an attempt to stop Captain Atom after he starts to think of himself as a god, using his powers to heal diseases for some while coldly killing others at his whim. The revised depiction is heavily influenced by [[Doctor Manhattan]].<ref>{{cite web |last=Corley |first=Shaun |date=7 January 2025 |title=It Took Decades, But DC Now Knows What to Do With One of Its Most Powerful Characters |url=https://screenrant.com/justice-league-captain-atom-comeback-power-theory/ |accessdate=15 January 2025 |website=[[Screen Rant]]}}</ref> 

In ''Jenny Sparks'' #5, Atom's original DC Comics backstory is confirmed as canon. A willing army recruit famed for making "unheard of" numbers of kills, Adam was arrested for "brutal" behaviours in the jungle in 1968 (potentially having been framed). To avoid hanging, he participated in an experiment to test whether a recovered alien ship could withstand a nuclear attack. The molten ship appeared to kill Adam, but he reappeared decades later as Captain Atom &ndash; true to form, he promptly enlisted again in the U.S. army and later the Justice League, where "no one gave him much thought" and he was viewed as "generic". More recently, he checked himself into a mental hospital, before leaving with a [[god complex]].<ref>''Jenny Sparks'' #5 (2024)</ref> After being captured by [[Gorilla Grodd]]'s [[Legion of Doom]] and having his powers partially drained in the "[[We are Yesterday]]" crossover story, Captain Atom is saved by Ryan Choi and has an epiphany that he should use his powers once again to do good.<ref>''The Atom Project'' #4 (2025)</ref>

==Powers and abilities==
===Powers===
Captain Atom's body is coated in the alien metal Dilustel, which enables him to generate vast amounts of nuclear energy and makes him virtually immortal. Atom's skin is highly durable and can only be damaged by the X-Ionizer, a device designed to cut through it.<ref>{{cite web |title=The Unofficial Silver Shield I Biography |url=http://www.dcuguide.com/who.php?name=silvershield |access-date=2011-01-15 |publisher=Dcuguide.com}}</ref><ref>{{cite web |title=The Unofficial Cambodian, The Biography |url=http://www.dcuguide.com/who.php?name=cambodian |access-date=2011-01-15 |publisher=Dcuguide.com}}</ref> Cracking or rupturing his skin causes Atom to leak radiation at an uncontrollable rate, which causes him to run the risk of atomic detonation.

In addition to his superhuman abilities, Nathaniel Adam is also an experienced [[United States Air Force]] pilot. He is especially skilled in combat piloting, is trained in military weaponry, strategy, and hand-to-hand combat, and speaks multiple languages, including [[Russian language|Russian]].<ref>''Captain Atom'' vol. 2 #31 (July 1989)</ref><ref>''Captain Atom'' vol. 2 #33 (September 1989)</ref> Adam also has strong survival instincts derived from his experiences during the Vietnam War.

At other times and storylines, Captain Atom has had different or greatly increased powers. During his Monarch era, his powers significantly increased, making him a [[Multiverse (DC Comics)|multiversal]] level threat. The short-lived [[The New 52|New 52]] version of the character was an "energy-based life form" whose control over physics meant he could transform lava into snow and manipulate time.<ref name="Captain Atom' 2011"/>

Captain Atom has his own enemies:
* '''[[Bolt (DC Comics)|Bolt]]''' (Larry Bolatinsky): An assassin and mercenary sporting an electrokinetic suit hired by General Eiling for a number of militia hero sales schemes. Often came in conflict with Captain Atom over the course of his military career while under contract in another of many government staged publicity stunts.
* '''Doctor Spectro''' (Tom Emery): A scientist driven mad by his emotion-altering prisms, Dr. Spectro gained the ability to affect emotions directly. Post-''Crisis'', Spectro was a small-time crook [[General Wade Eiling]] used to create a cover story for Captain Atom.

* '''Fiery-Icer''': A mercenary with a suit that unleashes intense fire from his right gauntlet and frigid cold from the left, the mysterious Fiery-Icer fought Captain Atom on several occasions.
* '''[[General Wade Eiling]]''': Once his commanding officer in the military who even in his new identity Nathaniel Adam often butted heads with due to his unscrupulous means of promoting America's new military assets. Unknown to the Captain for the longest time, it was the corrupt general who had Adam framed for killing a senior officer which, in turn, subjected him to the Atom Project years ago.
* '''The Ghost''' (Alec Rois): A physicist who developed a teleportation device that he used to become a millionaire, Alec Rois took on the persona of the Ghost and became Captain Atom and his partner [[Nightshade (DC Comics)|Nightshade]]'s Pre-''Crisis'' nemesis. Post-''Crisis'', he was a cult leader nicknamed ''the Faceless One'', a disgruntled weapons developer and a former CIA operative who sought revenge against an unscrupulous employer. Having been trapped in the Quantum Field by his own '''Stealthray''' tech, he is released as an energy being who controls teletranslocation through it and has connections to Atom's past conviction while enlisted five years ago.
* '''Iron Arms''': A mercenary that employs a backpack that powers powerful cybernetic arms.
* '''The Cambodian''' (Rako): An arms dealer and personal enforcer of the Post-''Crisis'' Ghost. A survivor of a U.S. bombing raid during the Vietnam War, this Cambodian refugee was taken into Rois' services while he was a government agent. Acting as the Green Elite's hitman, Rako framed Nathaniel Adam for treason under Rois' orders, resulting in his drafting into Project: Atom. As the Cambodian, he would clad himself in armor and weaponry tempered by the X-Ionizer, wielding a skein sharp enough to pierce Captain Atom's Dilustel armor.
* '''[[Major Force]]''' (Clifford Zmeck): A rapist/murderer exposed to the same experiment that created Captain Atom, he would regularly betray the U.S. government or go back to work for their more clandestine, i.e., crooked, organizations, becoming a regular as Captain Atom's Post-''Crisis'' nemesis.
* '''[[Hank Hall|Monarch]]''' ([[Hank Hall]]): In an alternate future, Hank Hall goes mad and kills Earth's heroes to conquer the world. When the hero [[Waverider (character)|Waverider]] comes back in time to prevent this, he instead creates the paradox that made his future possible. When Monarch goes back in time to retrieve his past self, it was Captain Atom that failed to stop him. Captain Atom battled the villain through time to quell the guilt of his failure to stop him earlier.
* '''[[Plastique (character)|Plastique]]''' (Bette Sans Souci): A French-Canadian terrorist with explosive-based powers and intense separatist designs, first came in contact with Captain Atom during an assassination attempt at a Canadian/American peace delegation.
