Bobobobs S01 E03 The Demon of the Universe

The Bobs crash land on a planet inhabited by monsters, and only Cornelius can save them from the most dangerous of them all - a "hairy hermit" called the demon of the universe who curses the crew and takes over Cornelius's body. Cornelius eventually casts the demon out and with help from the crew he burns him into the depths of space with a giant fireball.
