San Sui of the Xiang River travelled around throughout the centuries, testing his fighting skills against those he deemed worthy opponents. The chinese characters for "San Sui" are mountain and water, as he rumored to be as strong as a mountain and as a powerful as a river. He was also given the nickname "Iron Fist," from ringing a huge bell with his bare fists a thousand times at night at a temple in Hunan Province.
San Sui eventually ventured to Sunnydale, where he fought and killed Sunnydale High school karate champion, Lloyd Modano, which attracted the attenion of Buffy and the Scooby Gang. Sui tested Buffy's reflexes by sending his acolytes to attack her, observing from afar. Sui eventually faced Buffy, when he attacked Xander's martial arts class. Overpowering her in strength, Sui nearly killed her, but was impaled from behind by Xander.
Three years later, Buffy met up with Sui again, along with almost all the other demons and vampires she had slayed in the past. When the Hellmouth swallowed Sunnydale, all of the demons she ever killed returned to fight her in a gladiator-staged fight. Battling for four days straight, Buffy faced twenty-six challengers and defeated them again, facing San Sui as her twenty-seventh. Sui managed to get the upper hand over Buffy, and nearly killed her when outside help arrived to save her and help her escape the gladiator ring.
