The Ending Of TMNT: Mutant Mayhem Explained

Contains spoilers for "Teenage Mutant Ninja Turtles: Mutant Mayhem"

"Teenage Mutant Ninja Turtles" began as a cult black-and-white (and surprisingly violent) comic book series from creators Kevin Eastman and Peter Laird, which debuted in 1984. The basic premise of the series was — well, it's all right there in the name, isn't it? Essentially, every iteration of "TMNT" –- from the original comics to the various shows to the movies -– follows four teenagers (Leonardo, Michelangelo, Donatello, and Raphael) who happen to be turtles mutated by glowing green ooze that makes them sentient and humanoid, who are then trained to become ninja warriors by their also-mutated rat master and father figure, Splinter.

The 2023 CG-animated version, "Teenage Mutant Ninja Turtles: Mutant Mayhem," follows much of the same template. Splinter (voiced by Jackie Chan) raises the four titular turtles (Micah Abbey, Shamon Brown Jr., Nicolas Cantu, and Brady Noon) to fear humans and use their ninja skills to protect themselves (and collect groceries). Eventually, however, the Turtles meet up with Superfly (Ice Cube), and his cadre of villainous mutants — voiced by an all-star cast, including Seth Rogen (who executive produced the film) as warthog Bebop — who want to wipe out all of humanity.

Luckily, the film does go down its own path by the end. In fact, it makes some narrative choices that change up the "TMNT" status quo. This includes the Turtles' status in the world, the fates of many of the villains, and how the new franchise might implement other iconic characters going forward.

At the end of "Teenage Mutant Ninja Turtles: Mutant Mayhem," the Ninja Turtles have to work together to stop Superfly's genocidal plan. They accomplish this by destroying the superweapon Superfly had been building throughout the film. The Turtles even eventually get the help of Superfly's mutant minions — which include classic "TMNT" comic and cartoon mainstays like Bebop as well as Rocksteady (John Cena), Mondo Gecko (Paul Rudd), Genghis Frog (Hannibal Buress), and more — who were never really on board with killing all the humans anyway. The mutants even confess to the Turtles that they only went along with Superfly's villainous plan because they were convinced by him that it was the only way they'd ever be accepted in the world.

However, after the initial battle, while they all indeed succeed in destroying Superfly's super-weapon, Superfly, unfortunately, transforms into "Super Duper Fly," a giant kaiju-like monster rampaging throughout New York City. It then takes all of the Turtles' individual skills — Leonardo's leadership, Raphael's brute strength, Michelangelo's ability to think on his feet, and Donatello's superior battle tactics (as well as his knowledge of defeating giant monsters from watching a lot of anime like "Attack on Titan") — to finally take Super Duper Fly down once and for all, saving the world and all of humanity.

Like practically all post-MCU superhero movies these days — including non-MCU superhero films like 2019's "Shazam!" and 2018's "Spider-Man: Across the Spider-Verse" — 2023's "Teenage Mutant Ninja Turtles: Mutant Mayhem" includes a post-credits sequence at the end of the film that teases an upcoming villain. In it, we find the evil CEO of TCRI, Cynthia Ulrom (Maya Rudolph) lamenting that she still needs to capture the Turtles at some point to continue extracting (i.e. "milking") them and finish her plan of creating mutated animal-human hybrid super-soldiers. However, she also explains to an underling how now that the Turtles are fully integrated into the public, it'll be more difficult to capture them.

However, she knows exactly the person to pull that job off ... which of course leads to the film introducing this film universe's version of the iconic "TMNT" villain, Master Shredder. Unfortunately, we only see him briefly from behind, covered in shadows, and standing on a dark, rainy rooftop at night. It's also obvious this version will be possibly even more spiked-covered and extreme than most previous versions of the character. Presumably, his role will be to track the Ninja Turtles down and bring them to Utrom and TCRI — perhaps to keep the company's name clean, as he'd be hired as a third-party mercenary.

Another important message of the "Teenage Mutant Ninja Turtles: Mutant Mayhem" film is the importance of found families. This, of course, refers to Splinter taking care of the baby Turtles and raising them as his own. We see the struggles he goes through with learning to trust his growing children to make their own decisions as they get older, despite the dangers of the world. However, it also refers to the mutants as well. After TCRI goons capture their creator Dr. Baxter Stockman (Giancarlo Esposito) during the opening of the film, Superfly rescues his fellow mutants from harm and raises all of them on his own as a big brother to all of them. Even Baxter Stockman's motivation for creating the mutants in the first place was to create a family of his own.

Luckily, at the end of the film, The Turtles and Splinter allow Superfly's former mutant family to live with them in the sewers. We even see all the mutant characters –- which includes Mondo Gecko, Bebop and Rocksteady, Wingnut (Natasia Demetriou), Genghis Frog, Ray Fillet (Post Malone), Leatherhead (Rose Byrne), and Scumbug –- settled into the Turtles' home as they get ready for school. In fact, Scumbug and Splinter are seen to be a romantic couple by the end. It's an interesting turn of events, as Splinter has never had any romantic entanglements in any other version of the "TMNT" property. So it'll be interesting to see how the Turtles deal with being raised by a stepmother for the first time.

The ending could also have a much more sinister connotation — even if it's most likely unintentional by the filmmakers themselves. This would be the fact that "Teenage Mutant Ninja Turtles: Mutant Mayhem" potentially perpetuates a version of the "Model Minority Myth." Essentially, the "Model Minority Myth" states that a marginalized community only deserves recognition from the majority population when they do good deeds or are productive in society in some way (usually needing to go above and beyond to achieve this). In countries, like the United States, which has a history of slavery, colonization, immigration, and rampant marginalization, it's common for the powerful majority to dictate what is needed to constitute being a "model citizen" (hence the name). The myth is also often used as a cudgel to deny rights or citizenship to other, separate marginalized identities.

While the Ninja Turtles are heroes to the world and accepted by human society, they are seemingly only accepted precisely because they're heroes and wouldn't have been otherwise. April even says that the only reason she wasn't scared of the Turtles when she first saw them was because they had saved her life and rescued her scooter from criminals. It's even played as a comedy beat, where the Turtles ask if other people would accept them as she would, and she flat-out says, "No." This is a dark sentiment, since their sentience and intelligence should be enough to guarantee them a place in society.

Cynthia Utrom is another villain character, like Superfly, who was created specifically for "Teenage Mutant Ninja Turtles: Mutant Mayhem." She is the CEO of the evil TCRI and is on a mission to "milk" (i.e. "extract ooze from") the Turtles to create a race of animal-hybrid super soldiers to sell to the U.S. military. However, while she doesn't seem to have an obvious analog from the "TMNT" comics or any of the other associated cartoons or films, she might be related to — or possibly be a new version of — another popular villain from the "TMNT" universe. Cynthia Utrom's last name is actually the name of the alien species that the famous villain Krang belongs to. He's the pink, brain-shaped alien who rests in the belly of a giant robot. Furthermore, Krang and the Utroms are known to be associated with TCRI in the comics and various cartoon continuities, and in some continuities, they are actually even responsible for the ooze that created the Mutant Ninja Turtles.

Not only that, but Cynthia's look — including her yellow-and-pink glasses, general color scheme, and elevated hair-do that evokes the color and shape of the original robot's silver antennae — seems to possibly suggest that she could be a female version of the robot controlled by Krang or another Utrom alien antagonist. But we'll have to wait for the "Mutant Mayhem" sequel to know for sure.
