Concept artist Maxime Mary has shared some artwork from Teenage Mutant Ninja Turtles: Mutant Mayhem, and it features the Heroes in a Half-Shell sporting some alternate outfits from a key moment at the end of the movie.
If you haven't seen Mutant Mayhem yet, spoilers follow.
After saving the city from the rampaging Super-Duper-Fly, Leo, Mikey, Raph and Donnie are accepted by society and enrol in high school. We then see the Fearsome Foursome arrive for their first day wearing "normal" clothes.
"As you seem to like the silly outfits, here is a new pass on the turtles," Maxime captioned the post. "The idea was simple : they don't know how to properly choose and wear their clothes, so it was funny to imagine how far they can go, while keeping their identity. A very fun pass."
“After years of being sheltered from the human world, the Turtle brothers set out to win the hearts of New Yorkers and be accepted as normal teenagers through heroic acts. Their new friend April O’Neil helps them take on a mysterious crime syndicate, but they soon get in over their heads when an army of mutants is unleashed upon them.”
Micah Abbey, Shamon Brown Jr., Nicolas Cantu and Brady Noon will voice the roles of Donatello, Michelangelo, Leonardo and Raphael, respectively. The cast also includes Jackie Chan as Splinter, Hannibal Buress as Genghis Frog, Rose Byrne as Leatherhead, Ice Cube as Superfly, Natasia Demetriou as Wingnut, Ayo Edebiri as April O’Neil, Giancarlo Esposito as Baxter Stockman, Post Malone as Ray Fillet, Paul Rudd as Mondo Gecko, and Maya Rudolph as Cynthia Utrom.
Jeff Rowe (The Mitchells vs. the Machines) directed Teenage Mutant Ninja Turtles: Mutant Mayhem, which is produced by Seth Rogen and Evan Goldberg.
