Mike

Mike is a karaoke robot created and programmed by Dr. Crygor in the WarioWare series. He was created to serve as an assistant for Dr. Crygor, though he doesn't always get along with his creator. He appeared in a challenge set called RhythmWare 1 in Megamix. He is featured in Fillbots set, replacing the medium robots, in his multiple mass-produce copies that must be filled up with blue oil instead of red. The large robots are still presented in this game.
