When the Justice League extended invitations to the heroes of Earth following the Thanagarian Invasion, Captain Nathaniel Adams answered the call by joining as Captain Atom. Though he was a dedicated and respected member of the League, when his Air Force commission was suddenly reactivated, he stayed true to his allegiance with the United States military. Under orders, he was to keep Superman and Huntress from taking Question from a Cadmus facility, where he was being interrogated. This led to a fight between Superman and Captain, and, eventually, Captain Atom was defeated and taken back to Watchtower by Superman to undergo recovery. After this incident, Captain Atom was once again a devout member of the League.
