Fake Robotnik looks like a fat version of Robotnik with fake arm. He says that he lost his real arm when he was inventing Promotion. Promotion fired its lazor in his arm. Everyone knows that this is a pack of lies anyways. He is a Happycat minion. Most of time Fake Robotnik watches TV, especially Dr. Robotnik's TV show. Sometimes he invents stuff like Large Hadron Collider or Virtual Boy. He also tries to kill Sonic, but instead of Real Robotnik who uses Nincombots, Fake Robotnik uses nuclear missiles and tanks. But this doesn't work.
