Charlton Comics (Silver Age)
The Charlton Comics version of Captain Atom was Allen Adam. The character's origin had Adam working as a technician in a special experimental rocket when it accidentally launched with him trapped inside. Adam was atomized when the rocket exploded while entering the upper atmosphere.[8] However, he gained superpowers that allowed him to reform his body safely on the ground. Adam was outfitted in a red and yellow costume that was designed to shield people from his radiation. When he powered up, his hair became silvery-white.
Captain Atom was first published in a series of short stories in the anthology series 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, 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, published in cooperation with Charlton Comics, gives the character's name as N. Christopher Adam.[9] A later issue of a showcase comic book series published by Charlton also by the name of Charlton Bullseye gave the character's name as John Adam.[10]
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. A profile for the Charlton version of the character in Who's Who: The Definitive Directory of the DC Universe identifies him as Nathaniel Christopher Adam,[11] building off the name listed in Charlton Bullseye, which would go on to become the name of the post-Crisis version of the character.
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.[12]
This modern captain's name is established as Nathaniel Christopher Adam, a United States Air Force officer and Vietnam War veteran. Adam had been framed for a crime and was, under military justice, condemned to death; this taking place under the purview of Colonel Wade Eiling in the year 1968. As an alternative to execution, Adam was "asked" to participate in 'Project: Captain Atom', a military experiment with a slim chance of survival. He agreed to this in exchange for a pardon. The experiment involved testing the hull of a crashed alien ship's durability by placing Adam within the metal craft and then exploding an atomic weapon under it. The weapon went off and Adam was seemingly disintegrated. Eighteen years later, Adam suddenly reappeared. The alien metal, now bonded around his body, afforded him incredible abilities far beyond that of a mere mortal. Bonded with the metal, Nathaniel Adam now had powers that resulted from the metal's ability to tap into the "Quantum Field".[7][13]
Monarch
In Infinite Crisis, Captain Atom returns when Superboy-Prime punctures Breach, who wields similar energy-manipulating abilities. The end of Armageddon has him reappear in the devastated Blüdhaven, where he is used to administer radiation treatments. Atom later escapes from Blüdhaven and kills Major Force. After being fitted with an updated version of the Monarch armor to contain his radiation, the Captain awakens. Seeming to be mentally unstable, he breaks free, apparently kills the rampaging Major Force, and then releases a vast amount of energy, obliterating what is left of Blüdhaven. He remains missing until Kyle Rayner, then known as Ion, discovers him in the Bleed, a place between dimensions.[14]
Countdown
In Countdown to Final Crisis, Captain Atom assumes the Monarch name and battles heroes throughout the multiverse.[7][15]
Countdown
In Countdown to Final Crisis, Captain Atom assumes the Monarch name and battles heroes throughout the multiverse.[7][15][16] In the series Countdown: Arena, Monarch lures his 51 alternate universe counterparts to murder them and absorb their power.
During a fight against Superman-Prime, Atom's suit is damaged, releasing a chain reaction that destroys Earth-51.[17] It is later revealed that the Monitor Solomon attacked Atom in Blüdhaven, rupturing his skin and facilitating his transformation into Monarch.[18]
Project 7734
During Jimmy Olsen's investigation about Project 7734, the secret black-op commanded by Sam Lane to fight extraterrestrial menaces on Earth (including Kryptonians), it is discovered that an amnesiac and brainwashed Captain Atom is in his possession.[19]
Generation Lost
Captain Atom appears as one of the central characters in Justice League: Generation Lost, a maxi-series that takes place during the wider Brightest Day event. At the start of the series, Captain Atom is recruited as part of a massive group of superheroes tasked with hunting down Maxwell Lord, who had murdered Ted Kord. During an encounter with Lord at the Justice League's former New York headquarters, Captain Atom is rendered unconscious alongside Fire, Ice, and Booster Gold. The former Justice League members awake to discover that Lord has used his mental abilities to erase his existence from the minds of every single human on the planet, save for those present at the embassy.[20]
During a battle against the new OMAC known as OMAC Prime, Captain Atom allows OMAC Prime to absorb his energy, before reabsorbing the energy and overloading his powers, resulting in him being thrown into the time stream once again. Before being transported through time, Captain Atom threatens to pull Maxwell Lord into the time stream as well unless he undoes the global mindwipe of his existence. Lord complies and restores everyone's memories of him before Captain Atom is pulled away to a time and space unknown.[21]
The New 52
In The New 52 reboot of DC's continuity, Captain Atom is reintroduced with altered powers, appearance and origin. He is still USAF pilot Nathaniel Adam. In the new reality, Adam volunteers to participate in an experiment conducted by a research facility called the Continuum. At this facility, Dr. Megala's research is focused on the quantum field and on "dimensional transfer through M Theory". Adam is asked to pilot the dimensional-transfer vessel by Dr. Megala, who is now presented as a particle physicist working out of Colorado, but is seemingly atomized during the experiment. Soon afterwards, he reappears, now an energy-based life form. According to Dr. Megala, Captain Atom's abilities are largely nuclear in nature and involve tapping into the strong nuclear force, the energy that binds protons and neutrons in the nucleus. Adam's physical atoms are constantly splitting apart, giving him incredible power. His body maintains integrity by instantly re-merging these atoms, but extreme use of his powers can interfere with this process and cause Captain Atom's form to become unstable. This leads to a fear that at some point Captain Atom's brain might lose its molecular stability and he will not be able to fix it before it impairs his consciousness or causes him to suffer some form of brain death.[22]
During a fight with Dr. Megala, who has taken control of Firestorm's body, Atom absorbs a massive amount of energy, which disperses his molecules across the timestream. One of these pieces becomes a separate entity named Nathaniel Adym and joins the Science Police in the 31st century.[23]
DC Rebirth: The Fall and Rise of Captain Atom
Captain Atom (Nathaniel Adam) lost control of his powers and caused a devastating accident in this six-issue series set in 2012. Needing to contain his unstable abilities, he went into Dr. Megala's Subterranean Suppression Dome but seemingly exploded.[25] The world believed Nathaniel Adam was killed in a blast; However, Adam took a subatomic trip through time and ended up without powers, 20 years in the past.[26] It is revealed that the quantum blowback sent him back in time to 1994 as a normal man. Adam's wound distorted after being shot during an attempted car robbery, and his body was encased in liquid metal.[27] As a result of the time stream correcting itself, he was thrown back to 2017.[27]
DC All In
In 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.[28]
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 – 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.[29]
