Bane got a bunch of weird parascites on him. Parascites may sound bad, but they created an armor capably of stoping any blaster bolts that got by his lightsaber and force powers. It was also capable of stoping a lightsaber unless it was a hard, heavy, and was in contact with his armor for several seconds. Usually you wouldnt have several seconds. The armor gets even better, it pumped adrenaline into his vains, giving him extreme indurance and strenght. He was also the only one of several thousand Jedi and I am unsure howmany Sith to survive the Sith thought bomb at the battle of Ruusan.
Bane rules. also, that picture dosent show his armor. It is shown on the New essential guide to characters.
