Mega Shredder (2012 TV series)

Mega Shredder was created after Bebop and Rocksteady baited the Shredder Mutants into Baxter Stockman's large tank of mutagen. Even though this mutant's creation wasn't intentional, it resulted in the making of the super-sized super mutant, which is the largest mutant that was seen on Nickelodeon's Teenage Mutant Ninja Turtles to date.
