Turtles 4-Ever

Turtles Forever 2 is an upcoming television film produced by Nickelodeon Animation Studio and Mirage Studios. The movie is a crossover film featuring four different incarnations of the titular heroes throughout the franchise's history: the original Prime Turtles team from the 1984 comic book series, the light-hearted, family-friendly characters from the 1987 animated series, the darker, more serious cast of the 4Kids' own 2003 animated series, and the 15-year-old cast of the Nickelodeon's own 2012 animated series - in an adventure that spans multiple parallel universes. It also marks the finale of the 2012 animated series. This movie was produced in celebration of the 31st anniversary of the Teenage Mutant Ninja Turtles franchise.
