Beta and Gamma

Beta is a minor villain in Disney Pixar's animated film Up.

Biology

Beta is a muscular Rottweiler bearing a collar that translates his thoughts into words. He has black fur with two brown spots above his eyes, also having a brown underside.

Abilities

He is shown in the film as having the voice of a loud-voiced adult male. He is also depicted to be a fast runner in the chase scene, another part showing he has strong jaws when he and his pack bit Kevin, presumably breaking the bird's leg. When he heard Alpha's voice, he and Gamma criticized him, only stopping when Alpha threatened them.
