Teenage Mutant Ninja Turtles: Mutant Mayhem

Teenage Mutant Ninja Turtles: Mutant Mayhem is a 2023 American computer-animated superhero film. It is based on characters from the Teenage Mutant Ninja Turtles comic books by Kevin Eastman and Peter Laird.

Plot
Techno Cosmic Research Institute (TCRI) executive Cynthia Utrom sends a squad to hunt down rogue scientist Baxter Stockman, who has created a mutagenic ooze with which he intends to form his own mutant animal family, starting with a housefly. Baxter is interrupted by Cynthia's strike force and killed in the resulting explosion, while the mutagen falls into the sewers of New York City. The mutagen turns four turtle brothers—Leonardo, Raphael, Donatello and Michelangelo—and a rat named Splinter into humanoid mutants, whereupon Splinter adopts the turtles. Splinter distrusts humanity—particularly after one encounter where he and the turtles were chased away—and trains his sons in the art of ninjutsu, instructing them to only leave their sewer home to steal supplies. Over the years, the Turtles long to live with and like humans their age, much to Splinter's dismay.

Fifteen years later, the Turtles defeat a gang of criminals to recover a stolen moped belonging to a teenager named April O'Neil, revealing themselves and their origins. April, an aspiring journalist struggling to move past a viral incident of vomiting on camera, has been investigating a series of robberies of TCRI technology by a criminal known as "Superfly". The Turtles plan to stop Superfly and, through April's reporting, win public acceptance as heroes. They intercept a piece of stolen technology and meet Superfly under the Brooklyn Bridge, discovering that he is not only a mutant himself, but leader of a mutant gang. Ecstatic to meet fellow mutants, the Turtles bond with Superfly and the others and he reveals their creation at the hands of Stockman, explaining that they evaded TCRI and are living on an abandoned ship in Staten Island. He then reveals that he plans to use the stolen technology to mutate every animal on Earth and create a world where mutants have dominance over humans. 

The Turtles try to intervene, but the gang escapes with the equipment while a tracker TCRI installed on the equipment falls back with the Turtles, allowing them to be captured. At TCRI headquarters, Cynthia extracts the Turtles' mutagen, but April arrives with Splinter to rescue them. At the gang's hideout, Splinter and the Turtles convince them that their plan for domination will make them no better than the worst of humanity, and together they turn on Superfly, destroying his machine. However, the ooze falls into the water, combining marine wildlife with Superfly, who then transforms into a gigantic whale-like kaiju after grabbing animals from a nearby zoo. He attacks the city and the Turtles and other mutants attempt to stop him but are assumed by the public to be fellow monsters. 

Leonardo finds his voice as a leader while April overcomes her anxiety and commandeers a news broadcast to explain the mutants' good intentions and the citizens of New York come to their aid. With the help of the citizens and other mutants, the Turtles drop a canister of TCRI retro-mutagen into Superfly's blowhole, turning him back into a collection of normal animals. Reconciling with Splinter, the Turtles, April, and the mutants are celebrated by the city. The mutants soon move into the sewers with them. Splinter and Scumbug fall in love and the Turtles enroll at April's high school, where they are all embraced as heroes. While the Turtles and April enjoy themselves at prom, they are under surveillance from Cynthia (holding the now unmutated Superfly captive), who plans to recapture the Turtles by enlisting the aid of the mysterious Shredder.
