Bane is a hitman/ terrorist from south america.
Originally intended as a "dark mirror" of the highly disciplined and multi-skilled pulp hero Doc Savage, Bane spends his childhood in the hellish prison of Pena Duro on the corrupt South American island nation of Santa Prisca. He develops super strength through a forced experiment involving the drug Venom. Although his dependency on Venom is an immense weakness, Bane has been one of Batman 's most intelligent and physically powerful foes.
Bane is a very complex individual. He first appears to destroy gotham hired by the legue of shadows. He breaks batman's back leaving him to recouperate, in which Nightwing takes over. Later, after the legue of shadows are stopped, he sets up a bounty-hunting buisness in downtown gotham and becomes one of batmans allys. He gets very angry at times.
He has incresed strength due to the expiramental drug known as venom.
