Bane, the man who 'breaks people' in the DC comics. Whether he's hopped up on the drug Venom or not, he's a brilliant and imposing figure.
Assuming Joel Schumacher isn't involved, anyway.
A recurring villain, he first originated in Batman: Vengeance of Bane #1 (1993). Bane was born the son of an imprisoned revolutionary within the fictional Caribbean island nation of Santa Prisca, a corrupt dictatorship. The cruel government decides that child Bane must live out his escaped father's prison sentence, leaving him to grow up in the prison, Peña Duro (literally Hard Rock in Spanish), carrying around a teddy bear that he uses to conceal a knife.
Bane has a genius IQ and can speak a handful of languages, as well as being in peak physical condition, and having mastered several forms of hand-to-hand combat, he eventually becomes a 'King' of Peña Duro - something that catches the warden's attention. Desiring to break the so-called king, Bane is tortured and subjected to an experimental new drug called Venom.
While it has debilitating addictive properties with severe withdrawal symptoms, Venom increases the user's physical capabilities exponentially, giving Bane superhuman strength.
He uses said to strength to, well, break stuff, but not all things go his way.
