Overview: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.
