Tenshinhan

"I might just be a pothole in the road to you big guy, but it's going to be one heck of a deep pothole!"

- Tien

Tien Shinhan or Tenshinhan is a human introduced near the end of the Fortuneteller Baba Saga in the anime. Because of his harsh upbringing, he is initially cold and heartless, thinking nothing of exploiting innocents and inflicting pain. However, Master Roshi and Goku eventually help him to see the folly of his master's teachings, and he becomes their trusted ally.

22nd World Tournament
Tien appears at the start of the World Tournament along with Master Shen and Chaoitzu. Tien has Chaoitzu rig the tournament so that he can observe the others and fight the people he wants to. His first match after the preliminaries is with Yamcha. Yamcha is able to put up a decent fight, but even after using an imporved Wolf Fang Fist he is unable to hurt Tien. Yamcha resorts to a Kamehameha only to have it deflected back. Tien knockes Yamcha out and then breaks his leg for good measure.
