In the episode,
Count Dooku seeks to spring a Separatist prisoner from Republic captivity, but his profile prevents him from getting close enough to set in motion his malevolent plan.
Enter Cad Bane, the galaxy's most fearsome bounty hunter, as ruthless as he is deadly. He is quintessentially cold, cruel and calculating – and when the price is right, he can't be stopped. Backed by Dooku and the Separatists, he's bringing his unique skill set and impressive arsenal to bear against the very heart of the Republic. Bane brazenly brings the fight to the Senate's doorstep, with a rogues gallery of galactic scum as his allies...
Patterned after the laconic gunslingers of spaghetti Westerns, Bane is lethally cool and relishes being a bad guy. He is unflappable in the face of danger, and even welcomes the opportunity to pit his formidable skills against the legendary prowess of the Jedi Knights.
You know, they say this Cad Bane is one bad mutha... shut your mouth! Oh, and here's a couple pics.
