Transparent really enjoys being a ghost. He delights in being able to fly right through walls, and gets a real kick out of lowering the temperature in a room just by hanging out there invisibly for a few minutes. His favorite pastime is to immediately appear behind an unsuspecting Psymonster. Transparent is a real prankster, but it is all in the name of laughs for this high-spirited phantasm. And he doesn't mind being pranked in turn, either. One time, other Psymonsters got together and called an investigator from the Psymonster World to follow him around for a while. He is still laughing about that one.
He is a lime ghost with a yellow teeth and a dark green mouth with a green tongue.
