The Revival Machine is a machine Napoleon Bonaparte built. It has the power to revive anyone who is dead, as long as they have not been revived three times already. (there are some execptions) The workings of the machine are unknown, as it has so far only been known to be used to revive Mario, Bario and other people. Sometimes, it fuses people together, seemingly at random.
In the early days of the machine's invention, many things went wrong, resulting in a large zombie invasion that destroyed most of France and Belgium
trivia: if someone puts a banana in it the person being revived becomes immortal
