Turtles for ever is just actually a made-for-tv movie that is animated. Born in celebration of the 25th anniversary of this Teenage Mutant Ninja Turtles franchise, that the movie teams up various incarnations of their titular heroes--chiefly the lighthearted, child-friendly characters from the 1987 animated show and the darker throw of this 4Kids' own 2003 animated series--in an adventure that spans multiple universes.
