History[edit]

Radioactive Man once defeated Brain-O and handed him over to the police. During the fight, Brain-O hit Radioactive Man with a Xeno Ray Cannon, which was absorbed by Radioactive Man. This Xeno Ray energy then affected Radioactive Ape, causing him to go through multiple changes.^[1]

Brain-O the Magnificent was one of the many villains that Radioactive Man defeated before his supposed death.^[2]

Brain-O the Magnificent attended the wedding of Larva Girl and Radioactive Man. When fighting broke out at the wedding, Brain-O was defeated by Radioactive Ape.^[3]

Brain-O the Magnificent went undercover as the Superior Squad's new butler, Javier, in order to defeat them. Brain-O the Magnificent locked the Superior Squad in their Rumpus Room and set the automated training tools inside to attack them. The Superior Squad cut a circle in the glass out then Purple Badge of Courage punched him, knocking Brain-O's head off his body and down the stairs. A teenager then picked up his head and walked off with it.^[4]
