Buster, the Dog is the primary protagonist of the animated movie The Fearless Four. A bloodhound dog, Buster seems like a nice and gentle figure, until someone would provoke him into a feral state by pulling his tail, but other than that he appears completely harmless. He appears as one of the founding members of the musical group, the Fearless Four. Buster becomes involved in the conflict, between the heroes and the villains, in Heroes vs. Villains War, aiding the animal heroes on their journey to stop the schemes of the villains.
