The Psions are a fictional extraterrestrial species in the DC Universe. The Psions first appeared in Tales of the New Teen Titans (vol. 1) #4 (September 1982) and were created by Marv Wolfman and George Pérez. The earliest uncredited appearance of the Psions was in The Witching Hour #13 (March 1971), written by Wolfman.

The Psions are originally lizard-like aliens on the planet Maltus before being enhanced by the Maltusians. After the Maltusians leave, the Psions investigate their labs and mimic their creators, cutting off their tails to look more like them. After several millennia, the Psions leave Maltus to reunite with their creators, now known as the Guardians of the Universe. When the two species meet, the Guardians send the Psions to a distant galaxy where they will be undisturbed, preventing the Green Lantern Corps from interacting with them.

Discovering their creators and then feeling humiliated by the same, the Psions bury the truth, forget their background, and resume their scientific work. They repeatedly rediscover their origins, but suppress their knowledge soon after. The Psions refuse to acknowledge that their creators do not want or believe in them.

The Psions are among the many alien species who invade Earth after the Dominators became worried about humanity's ability to produce super-powered individuals. Part of their contribution to the war effort includes creating sedatives for prisoners in the gulag that the Alliance maintain in deep space. A science team also works out of Alliance Headquarters in Australia before being killed by a bomb that they intend to send to the Justice League International. A Psion is also part of the Paradocs crew during the Our Worlds at War crossover.

Psions has not been a contender in any CBUB matches.
