Mike is a boy who is most definitely a werewolf, with messy dark brown hair, as well as hair which goes down both sides of his head and on his hands. He has yellow sclera, large canine teeth, and obvious doglike ears. He wears a purple and yellow letterman's jacket and blue skinny jeans, complete with sky blue shoes.
His standard outfit is probably a reference to the 1985 movie Teen Wolf.
His Howl Outfit is a reference to Michael Jackson's Thriller.
