The Dark Knight Rises (2012)
Bane was recruited by the League of Shadows as a protector of Talia al Ghul while incarcerated. He was beaten so severely, he suffers chronic, excruciating pain. A penitentiary doctor created a mask that releases a stream of gas to numbs his pain, allowing him to function normally.
Bane fighting style is brutal, and heavy. He is fanatical and highly intelligent with a terrorist mentality.
