Another of the Koopalings and sure enough the biggest of the eight. He's bullheaded and foul-mouthed, tending to go off on an incessant tangent until one of his siblings, usually Roy, tells him to shut up. However brash and eager for violent behavior he is, he can come off as very slow and dopey whenever he points out the obvious or when he gets easily outwitted by the simplest tricks. Like Roy, Morton also has a soft spot for his "Mommy Dearest," the two usually fighting for Liz's attention.

Morton's voice should sound fairly deep, as bass as possible. Also, despite his low intelligence, I don't want him to sound stereotypically retarded or anything like that. Speak normally, only picking up the pace during his excited, motor-mouth moments (his first line).
