What is a real Bane mask?

A real Bane mask is a replica of the mask worn by the villain Bane in the movie “Batman: The Dark Knight Rises.” Bane requires the mask to constantly pump his body full of anesthetic, which relieves constant pain he suffers from a trauma he previously suffered.

Bane is a comic book character from DC Comics and is regarded as one of Batman's deadliest super villains. Bane famously killed Batman in the “Knightfall” storyline by breaking the hero's back. He is fueled by a steroid serum known as venom, which gives him super strength. Actor Tom Hardy portrayed Bane in “The Dark Knight Rises.”
