Bane is a powerful cyborg of unknown origins who sounds kinda like Sean Connery.
Bane claims to have once lived in an arcology housed within a robot comparable in size to Earth's moon. He arrived on earth some time in December 2011 A.D. In July 2012, he made himself well-known to the public when he launched a terrorist attack in Uzbekistan. He always claims to be in search of "masks of power" and so far seems unsuccessful aside from kitsch collectibles and antiques he found at flea markets.
He is very insecure about his large stature. When Bill Wilson mocked him for it, Bane deflected by pointing out that he was only large from Bill's perspective, and that Bill was small to him.
