Mike has a very outgoing personality, being very lively and good-hearted; sometimes talking even more than he should. Mike has a tendency to do crazy things and is very bold, encouraging violent acts on others when he has the opportunity to do so (which he canonically does to his boyfriend and lab rat Pac with dubious consent). He likes to cause chaos, even though he is quite reserved when talking to others. Despite getting into a lot of trouble, Mike hates making anyone upset.
