Captain Atom, real name Captain Nathaniel Adams, was a superhero and a member of the Justice League.
When the Justice League extended invitations to the heroes of Earth following the Thanagarian Invasion, Captain Nathaniel Adams answered the call as Captain Atom, nuclear-powered soldier of justice. The Captain was one of the first new League members to be given an important assignment: investigating a radioactive accident in Chong-Mai, alongside Supergirl and John Stewart. Captain Atom's conduct as a US military officer was too uptight for the lighthearted heroes like Kara and Green Arrow, which at first caused some animosity between them.
In loco, they found that the origin of the distress was a walking nuclear superweapon that had gone haywire. Captain Atom attempted to drain its energies but it was overwhelming, and he was knocked out. He then blamed John Stewart's injury on Green Arrow's refusal to work as a team, which escalated the tension between the trio. Afterwards, Captain Atom offered himself to personally shove carbon rod dampers into the flaming giant's reactor, fully aware that if could endanger his own life.
Captain Atom soon proved to be more than capable as a Justice Leaguer, and he quickly gained the respect and admiration of his colleagues, notably Superman, who selected the Captain as his partner while defending Metropolis from Mantis, a second-rate, would-be despot from Apokolips. However, immediately following this adventure Captain Nathanial Adams had his Air Force commission unexpectedly reactivated by General Wade Eiling at the behest of Amanda Waller of Cadmus and Lex Luthor.
Huntress from taking the captive Question out of a Cadmus facility. He was compelled to fight Superman hand-to-hand, and by controlling red-sun radiation, Captain Atom managed to amplify the impact of his blows against the Kryptonian. However, though acknowledging Captain Atom's valiant effort, Superman merely made sure that Huntress and Question had time to escape before he was forced to incapacitate Captain Atom. Cadmus security arrived on the scene to assist the Captain, but Superman sternly warned them not to touch his fallen comrade: "He's Justice League." Superman then collected Captain Atom and took him to the Watchtower, where the Captain could recover under the watchful eye of the League's medical and science staff.
Captain Atom rejoined the League during the invasion of the Watchtower by Galatea and the Ultimen clones. He was able muster enough strength to blast a few clones while Supergirl fought Galatea. Thanks to the revelation that Lex Luthor and Brainiac had been manipulating both Cadmus and the Justice League, it seems apparent that Captain Atom was discharged from military service and allowed to rejoin the Justice League following Amanda Waller's involvement in the conflict between the League and the Luthor/Brainiac hybrid.
Captain Atom was last seen fighting against the forces of Darkseid during the intergalactic despot's massive invasion of Earth. The Captain survived the conflict, so it is logical to infer that Captain Atom remained with the organization following Darkseid's disappearance.
