Thog

Thog is a hulking, dim-witted brute who turns up in the arena to smash things and be smashed in turn. He doesn't scheme or reason much—he flexes, grunts, and follows whatever order or instinct is loudest in the moment, a wall of muscle dropped into New New York's stranger corners.

He's a one-joke character executed with total commitment: the joke being that something this enormous and terrifying can also be a complete pushover, mentally speaking. Tress MacNeille's guttural, monosyllabic delivery makes every line land like a punchline, and Futurama never overexplains him—he's just there, huge and happy, and that's funnier than any backstory would be.
