Yamcha, the notorious desert bandit, started out as an antagonist of Goku but quickly became his friend thanks to Bulma. He lived in the desert, which resulted in him never having much female contact. Whenever he encountered Bulma, he would blush immensely and become petrified right on the spot.
Yamcha's trade mark move was known as the Fist of the Wolf Fang.
With this move, he would strike the opponent with his hands in a claw like pose with his middle finger, ring finger and thumb curled.
His best friend is a floating shift-shaping cat named Pu'ar.
Yamcha's cleaned up his act as a desert bandit and become a member of the Z-fighters as well as a student of Master Roshi.
Yamcha gained incredible ki control as displayed in his new signature move the Spirit Ball. With this move, he can guide a ki ball in any direction using his middle and index fingers.
When the Saiyans, Vegeta and his henchman Nappa, first came to earth. Yamcha was the first to die after Nappa planted the Saibaman.
In the Android Saga, Yamcha was the first to discover Androids 19 and 20 and was the second to be harmed by them (after Yajirobe).
