Mega Shredder was a gigantic crustacean mutant accidentally created by Bebop and Rocksteady.
After capturing Michelangelo and Leonardo, Rocksteady and Bebop had a plan to mutate the two into a giant two-headed turtle. Leo tricked them into dumping in the Shredder Mutants first and as a result, the three merged together into one massive mutant, dubbed Mega Shredder by Michelangelo.
Mega Shredder rampaged over New York City, leaving Leo and Mikey to attempt to stop it. Mikey gets swallowed by Mega Shredder, leaving a despondent Leo alone, until help arrived in the form of Donatello, Raphael, April, and Casey in the Turtle Mech. The four of them in the Mech held off Mega Shredder long enough for Michelangelo to break free from its innards, slicing its Oroku Saki-shaped tongue-brain. With a launch of an exploding barrel into the pained Mega Shredder's mouth, the Turtle Mech defeated Mega Shredder.
Method of Consumption Edit
The Mega Shredder simply grabs Mikey by one of its large hands and into throws him into his mouth, swallowing the mutant turtle whole. If one does not fall into the stomach acid in the monster's stomach, then they will still live.
