If you have seen the movie: The Bad Ass Sensei with long white hair.
If not, a bad ass sensei with long white hair, who (feel free to correct me here) dislikes caucasians, hates americans, and despises women. Not to mention, he dun feel all that kindly toward teh japanese. He was Bill and (beep) or, The Brides teacher, and just an all around cool guy,

IE: He obliterated an entire shaolin temple with his bare hands. Moral: respect thine elders.


PS- I know he's not a sensei, but thats the easiest word to portray him as, because Bad Ass AZN just didn't cut it.
