Mike is a loyal worker to Dr. Crygor, but also a sassy and rebellious singer that will jab at him any chance he gets. He'll usually do work without complaining, but he's usually sneaking off doing karaoke singing or starting a party. He's seems to be judgemental of other's singing skills as proven by how he mocks Crygor's singing and how he acts as a DJ judge for the Disco game in Game and Wario.
