The TV series Rise of the Teenage Mutant Ninja Turtles (Rise of the TMNT) could have introduced even more siblings into the show, according to series creators Andy Suriano and Ant Ward. The show, which ended after a few years, would have seen the Turtles' mutated origins and revealed that two other turtles were also part of the experiments that created them. The creators also revealed that future plans for the show would have included a "no-nonsense eldest brother" to disrupt the sibling dynamic between Rise’s version of Raphael and Leo. However, the show was curtailed for the movie sendoff and instead ended in a 2022 Netflix movie. The Art of the Rise of The TMNT by Colin Stein, being published by IDW, confirms that two long-missing extra turtles would have been included in the story if Rise hadn't been cut short.
