There are many cross-overs and dream match-ups that fans would love to see. One of them were brought to reality with the animated film Batman vs Teenage Mutant Ninja Turtles (2019).
In this scene, Batman completely washes the turtles from beginning to the end. With prep or no prep, Batman is a black belt and master in multiple forms of martial arts, including Ninjitsu. Fighting all four of the ninja turtles at once is no difficult task.
For those who are only watching the clip, Batman and the turtles are not enemies. This is just there first encounter and they don’t know who each other are. This fight scene and eventual team-up later as the film progresses is basically fan service and great for all of us as fans to see. Even though the animation and fight choreography is subpar, the art style still looks amazing. We hope to see more team-ups by well known animators in the near future.
