Yamcha
Yamcha was a warrior who fought alongside Goku and the other Z Warriors many a time. Born in the year 733, Yamcha was originally a thief with a fear of women, but changed after he and Bulma became romantically linked. This relationship lasted for a long time, but Bulma became fed up with Yamcha (she kept catching him in embarassing situations that weren't his fault) and left him for Vegeta. The two did remain good friends, however.
Around the time of Raditz's attack, Yamcha had been pursuing a career in professional baseball for the last five years. He left this job to battle the two Saiyans who were due on Earth in a year with the other Z Warriors. He was destroyed by one of their Saibamen, but was resurrected some time later by the Namekian Dragon Balls.
During the crisis with the androids created by Dr. Gero, Yamcha was nearly killed by Android 20. Fortunately, his friends were on hand with a senzu bean to heal him. After the Cell Games, Yamcha settled down and ceased his training, but was never with any other woman after Bulma.
Techniques
Yamcha had a few signature techniques- these included the Spirit Ball and Wolf Fang Fist attacks.
