Buster (Lady and the Tramp)

Buster is the main antagonist in Disney's 2001 film Lady and the Tramp II: Scamp's Adventure, sequel to the 1955 film Lady and the Tramp. He is voiced by Chazz Palminteri with Jess Harnell doing his singing voice.

Personality
He is the leader of the Junkyard Dogs, and his breed appears to be a Doberman/Rottweiler mix. He is very interested in Angel and calls her "his girl," even though she utterly despises him and repeatedly emphasizes this.

Lady and the Tramp II: Scamp's Adventure
He is first seen throwing the dogcatcher's hat; later on when he discovers Scamp, he decides that before he can make him a "Junkyard Dog" he'll give him a "test" to show that he's brave enough. He is later seen watching Scamp's family from the bushes, and then tells Scamp that for his "final test" he wants him to wreck their picnic and steal their chicken. Scamp does so to prove that he isn't a house dog. He then meets up with Scamp (and Tramp) in a dead end alley where he reveals that he and Tramp were once best friends, but when Tramp ran off with Lady, he became jealous of her and decided he didn't like house dogs and went on with his life. But when Scamp gets trapped while running from the dogcatcher, he sees Buster and thinks he will rescue him. Buster refuses and leaves, ignoring him. When Scamp suddenly discovers that Buster was actually doing all this for revenge, he takes to finally realizing that a family is more than rules. After he escapes the pound, Scamp goes back to the junkyard, gets his collar, and traps Buster underneath a pile of junk. The other Junkyard Dogs ditch Buster, leaving him alone and stranded.
