A one-eyed demon, often helping Horribus run the Dimension of Pain. Psyk is most notable for his intelligence and chubby physique.

Psyk was sent by Horribus to kill Torg with the Demon Spear Calmadar at the halloween party of 2000.

After the invasion of the dimension of Lame, Psyk was most noted for his resistance against Horribus' obsession with finding Torg. When Horribus was eventually punished and demoted by the Demon King, Psyk was rewarded for his loyalty and leadership by being promoted to be the new Demon Lord. With the promotion Psyk changed name to Psykosis, gaining all the powers of demonic aristocracy.
