I have a couple I have in mind.
Emperor Belos: "FINALLY! I CAN CLEANSE THIS PERDITION....MYSELF!"
Lots-o'-Huggin' Bear: "This is what happens when you DUMMIES TRY TO THINK! WE'RE ALL JUST TRASH WAITIN' TO BE THROWN AWAY! THAT'S ALL A TOY IS!"
Mumkhar/Metal Face: "Her screams were music to my ears as my claws slid right through her soft flesh. Like a hot knife through butter!"
