The villains of Teenage Mutant Ninja Turtles have a lot in common: huge egos, terrible plans, and an uncanny ability to show up exactly when the pizza arrives.

Mutants, mad geniuses, and overengineered nightmares pile on the chaos with big speeches and even bigger confidence, absolutely certain they've finally got it all figured out. They don't. They never do. The result is explosions, invasions, and the kind of mess that somehow always lands back in the turtles' laps.
