Turtles Forever is a made-for-tv animated movie. Produced in celebration of the 25th anniversary of the Teenage Mutant Ninja Turtles franchise, the movie teams up different incarnations of the titular heroes—chiefly the light-hearted, child-friendly characters from the 1987 animated series and the darker cast of the 4Kids' own 2003 animated series—in an adventure that spans multiple universes.

Leonardo, Raphael, Michaelangelo and Donatello must save New York City from the evil crime lord Shredder and his assistant, Baxter Stockman. The Turtles must fight foot soldiers, mice, and gangs and get help from their sensei Splinter, her friend April O'Neil, and her partner Casey Jones in an action-packed new series.
