Doomax a.k.a "Doomsday Device of Doom", also DDD and DDDD, is a gadget that can release unexpected chaos and gloom over the whole planet. It was designed by aliens with a rather dark sense of humor. They gave it to humans as a gift, but they knew it hides a powerful dooming power that eventually humans will release. Since then, the Hideous Order of the Dark Knights tries to find this gadget, just to destroy it, preventing the fatal disaster.
