Mike is a mouse from the upcoming Universal film, Sing. He is voiced by Family Guy creator/cast member Seth MacFarlane. Since his profile says he's a con mouse, he is most likely to be the film's main antagonist, but it's currently unknown. For all we know, he could be a neutral. In Thomas the Tank Engine's Adventures of Sing, he is the main antagonist. In Barney's Adventures of Sing, he partners up with Bellwether, but later betrays her.
