Beast himself when Belle returns and begs for Gaston to not kill him.
Eric from The Little Mermaid spends a good portion of the film getting jerked around in one way or another, then the sea witch tries to kill Ariel, and he introduces Ursula to Mister Giant Pointy Stick.
Despicable Me, towards the end, when Vector has captured the girls, and refuses to release them, even though Gru gave him the Moon.
