The history of Immortus has not been revealed, but he is apparently a brain that has been implanted into his powerful robot body. He was recruited by Saturn Queen for the Legion of Super-Villains. Immortus attempted to help Saturn Queen destroy the Rock of Eternity, but could not do so with his own power.
Powers & Abilities
Immortus’ body is made of self-regenerating Inertron, making him virtually indestructible and allowing him to heal almost instantaneously even if something does manage to harm him. He is also super-strong, fast, and has extensive programming in combat.
