Note: Dysfunction Junction applies to pretty much every single character listed here. Of course, it's a Justified Trope, due to the effects of Psitanium, the fact that several characters reside at an insane asylum, the social status of psychics... The world of Psychonauts also possesses an Amazing Technicolor Population in about half the cast.
