- Title: Teenage Mutant Ninja Turtles – The Lonely Mutation of Baxter Stockman
- wiki: link
After struggling to find a cure to return both April‘s (Mae Whitman) father and Master Splinter (Hoon Lee) into humans, Donatello (Rob Paulsen) succeeds in creating two doses of Retro-Mutagen. However, before the Turtles can save April’s father they are attacked by the newly mutated Baxter Stockman (Phil LaMarr) whom the Shredder (Kevin Michael Richardson), tired of the scientist’s many failures, has mutated into a giant insect.
Accidentally destroying half of the cure while trying to procure it for himself, Stockman kidnaps April and demands the remainder of the Retro-Mutagen in return for the Turtles’ friend. The arrival of Razhar (Clancy Brown), also demanding the Retro-Mutagen, doesn’t help the situation. During the ensuing fight April is dropped into a vat of Mutagen but doesn’t mutate when it’s revealed she is immune to the compound (although the reason for her immunity remains a mystery, much like her unexplained insights).
Eventually April’s father regains his humanity, although Shredder’s soldiers and Splinter are left in their current state (something Splinter has long ago come to terms with). Although Baxter Stockman is no more interesting as a giant fly than he was as a evil scientist (though he does get off a single line teasing the possibility of Rocksteady and Bebop), “The Lonely Mutation of Baxter Stockman” provides fun moments including the nod to Donnie and Casey Jones (Josh Peck) rivalry over April’s affections and the return of Michelangelo‘s (Greg Cipes) Turflytle Costume, much to Raphael‘s (Sean Astin) dismay, as the two try to corral April’s father while their brothers work on saving her from Stockman.
