The Jack Bros. are the two mascot characters of the Megami Tensei franchise. They have appeared as silly, comedic characters in many of the games, and have been both opponents and allies (the "Hīhō", or "Hee-haw", in the title refers to the characters" signature laugh). One brother is a snowman called Jack Frost, the other a pumpkin named Jack Lantern (Pyro Jack). The game adds a third brother, Jack the Ripper, renamed Jack Skelton in the North American release. The story of the Virtual Boy game is that the brothers have taken advantage of Halloween to leave the fairy realm and haunt the real world; unfortunately, they have lost track of time, and must now find their way back to fairyland by midnight or be banished from it forever. (This was changed to disappearing out of existence forever in the English translation.)
