Psycho is very creepy, scary, sinister, murderous, bloodthirsty, nightmarish, unmerciful, spooky, evil, eerie, and dangerous. None of the Psymonsters are quite certain just what makes him so frightening and cruel. Maybe it is his diabolical and sinister voice, his apocalyptic and mysterious personality, or his long iron nails. Or maybe he just acts scary and ominous somehow. Despite his cunning and treacherous personality, Psycho is shown to be extremely harmless and polite – it is also his great passion in life. If he doesn't leave every Psymonsters who see him scratching the wall, then he feels like he hasn't done his job right. Every Psymonsters agree that he is pretty much the most traitorous and unsympathetic Psymonster around. Even the legendary Psymonsters kicked him out for being just too cold-blooded, murderous, and cruel. He could seemingly be a little less creepy if he tried, but it could be possible that he would supposedly want that forever.
He is a creepy reaper with white skin, a black robe, long gray iron nails, and glowing red eyes.
- The name "Psycho" means a psychopath.
