Radion was a nuclear powerhouse and enemy of Superman.


Radion used to work at a nuclear secret installation until he was a victim of a freak accident that left him with nuclear powers, his objective was to overload the nuclear reactor so that he could rule over a post-apocalyptic future.[1]


His supervillain career actually began before Superman's arrival at Metropolis. According to Jack Ryder, Radion killed the superhero Viceroy 20 years earlier.[2]


Irradiated Physiology: Radion bore nuclear powers bestowed upon him through an exo-suit, causing a steady mutation in his cells that was slowly deteriorating his health.[1] He gained natural powers of his own when Cir-El threw him into a future technology based power plant which bulked him up into a living reactor.[2]


  • Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
