An unexpected crossover but sounded exciting coming soon in the form of a Batman vs. movie. Teenage Mutant Ninja Turtles. Carrying the animation format, this project is the result of a collaboration between DC Entertainment and Nickelodeon, with Warner Bros. Animation which acts as an animation studio.
Although this is the first time bat humans and turtle ninja have met in a film, these iconic characters have actually been dueted in the Batman / Teenage Mutant Ninja Turtles (2015) miniseries. This comic by James Tynion IV and Freddie Williams II is the source of material for the film.
