Fridge is a murderous creature that was once very dangerous in PS World. After his defeat, his remains wound up in Compass World, where Electric Ying Ying used them to experiment on. Once he was revived, he wanted destruction of Biggert City, ultimately leading to the destruction of the one who killed him. He often jokes around, despite how terrifying he is. Fridge enjoys playing with his enemies and usually despises killing them right away (aside from those who cause him to lose his temper).
Bernard is the imaginary friend of Rudat who has great navigational abilities. This old man is also a very successful doctor who has amazing healing abilities. He is very strict and often in a bad mood though.
