TMNT: Battle Nexus

TMNT: Battle Nexus is a 2034 animated superhero film directed by Sage Cotugno from a screenplay co-written with Dana Terrace and Kevin Eastman, and based on the Teenage Mutant Ninja Turtles franchise by Eastman and Peter Laird. An adaptation of the series TMNT: Family Issues by Ciro Nieli, the film serves as a crossover between the series, Teenage Mutant Ninja Turtles (2003), and Rise of the Teenage Mutant Ninja Turtles (2018), with the lead cast from each series reprising their roles, and Kate Graham and Marc Thompson also starring. The film sees three iterations of the TMNT teaming-up to save the Battle Nexus and the multiverse.

The film was announced to be in development in early 2033, with its plot and cast being announced shortly after. The writers would study each iteration represented to make sure they are potrayed accuretly and keep continuity with each other. The writers would also intentionally avoid including the 1989 iteration due to said versions having already being promently used in crossovers.

TMNT: Battle Nexus was released on December 25, 2034, to generally positive reviews from critics, particularly for its vocal performances, inclusion of multiple TMNT series, and animation.
