Menancing Mental Masterminds: Psimon and Brain Wave

Simon Jones was a physicist fascinated with the concept of accessing other dimensional planes of existence. His experiments opened a portal wherein a bolt of energy irradiated and mutated him, transforming him into a psionic being. These new abilities corrupted Simon, motivating him into becoming Psimon, although he was actually the pawn of an extra-dimensional being. Shortly after this, Psimon was recruited by the supervillain Doctor Light into joining his Fearsome Five, alongside inventor Gizmo, matter-transmutter Shimmer, amd her superstrong brother Mammoth. Together, they fought the New Teen Titans repeatedly, each time leading to their defeat.

Henry King was a psychologist fascinated with crime, spurred on by his mutant mental abilities. King eventually adopted the alias of Brain Wave and repeately battled the Justice Society of America. Whether with henchmen or alongside the Injustice Society, each time he met with defeat. Eventually, King married retired superheroine Merry Pemberton, and together they had a son in Henry Junior. Through Merry, Henry also had an equally evil nephew in Athur Pemberton who founded the Strike Force, and a heroic brother-in-law in Sylvester "Star-Spangled Kid" Pemberton.

Eventually, after his latest scheme as a member of the Secret Society of Super-Villains had failed, King sided with his son against fellow villain Ultra-Humanite. However, in the mental war between the two, Ultra projected a mental blast which extinguish Brain Wave's life. Shortly after this, Psimon as one of the recuited supervillains aboard Brainiac's spaceship attempted to destroy the android and his ally Lex Luthor, however it was Brainiac who struck last... slaying Psimon with another bolt of energy.
