Dr. Muto is the titular protagonist of the Dr. Muto video game. He is a mad scientist whose inventions have always gone wrong. One day, he helps his home planet, Planet Midway, with an energy crisis caused by a company owned by his evil nemesis, Professor Burnital. Burnital, however, sabotaged the machine, and when it was turned on, it blew up taking the planet with it. At first, Muto thought it was all a nightmare, but when his hunchbacked sidekick Jankey shows him it was real, he, Jankey, and his wise-cracking computer AL, must build a machine from parts found on planets owned by Burnital's corporation and rebuild Planet Midway.
