Psimon is a fictional comic book supervillain from DC Comics created by George Pérez and Marv Wolfman. He first appeared in New Teen Titans #3 (January 1981) as one of the founding members of the Fearsome Five, which became a frequent enemy of the Teen Titans, Superman, and the Outsiders.

In New Teen Titans #5 (March 1981), Trigon, growing impatient with Psimon’s lack of progress, banished his psychic minion to another dimension. In New Teen Titans #7 (May 1981) the remaining members of the Five attacked the Titans at their new headquarters, Titans Tower, and used their dimensional transmitter to return their teammate to them, but they were subsequently imprisoned.

Psimon’s teammate Gizmo eventually broke the team out of prison, and Psimon, now acting as team leader, led the Five in kidnapping Dr. Helga Jace in order to force her to make them an army of "Mud Men" to aid them in their battles. However, they were again defeated, this time by the combined forces of Batman, the Outsiders, and the Teen Titans.

Psimon later allied himself with the immortal dimensional traveler known as the Monitor during the seminal 1985 event known as Crisis on Infinite Earths. During this, the rest of the Five, feeling betrayed by Psimon, turned on him, apparently killing him. In Pre-Crisis continuity, Brainiac and the Earth-1 Lex Luthor saved Psimon from the Anti-Monitor's Shadow Demons and recruited him for their Villain Army, taking over Earths 4, S, and X. He became suspicious of the two villains' plans and, learning that they were going to take over the worlds by themselves once the heroes and villains were wiped out, attacked the two. He apparently destroyed Brainiac and went to finish off Luthor, only to have his brain blasted away by a recreated Brainiac in one of the more brutal surprise deaths of the storyline.

Psimon has not been a contender in any CBUB matches.
