Yamcha

Yamcha is one of the support characters in Dragon Ball Z: Kakarot.

Saiyan Saga
Being a young bandit, Yamcha would steal money from those that passed through his wasteland. He initially joined Goku and company with the hopes of stealing the Dragon Balls from them but he eventually grew fond of them and became a good friend. Yamcha planned on using the Dragon Balls to overcome his shyness around women, but he was able to do so on his own after he and Bulma grew close and started dating. However this newfound confidence turned him into a womanizer, which did not sit well with Bulma and the two eventually split. He later gave up his bandit life and became a student of Master Roshi.

Together with Goku and Krillin, Yamcha entered the World Tournament three times, and was able to make it past the preliminaries each time only to lose soon afterwards. In his first tournament, he lost to Jackie Chun (Master Roshi in disguise): In his second. he lost to Tien; and in his third he lost to Earth's guardian Kami (in the body of a human). Yamcha is naturally kind-hearted and cares for his friends, as seen when he fought the Saibamen on Krillin's behalf.

Cell Saga
Shortly after being brought back to life with the Namekian Dragon Balls, Yamcha began to live with Bulma again at Capsule Corporation, but things became awkward when Vegeta moved in as well. Yamcha's willingness to live with a former enemy confused Tien, but Tien himself once broke Yamcha's leg in the World Tournament and Yamcha later forgave him. When Yamcha was nearly killed by the androids, he rushed to the aid of Goku and others with Senzu Beans after he had recovered from his injuries. After the Cell Games was over, Yamcha reassured Trunks that his father fought to avenge him after he was killed by Cell.

Majin Buu Saga
Similar to Krillin, Yamcha chose to give up martial arts after the Cell Games, even refusing to enter the World Tournament, fearing he would only embarrass himself. He and Bulma remain good friends, and any awkwardness over their past relationship is long gone.
