A former desert bandit, Yamcha was once an enemy of Goku, but quickly reformed and became a friend and ally. Brave, boastful and dependable, Yamcha is a very talented martial artist and one of the most powerful humans on Earth, possessing skills and traits that allow him to fight alongside his fellow Z Fighters when major threats loom. Although he retired by the latter half of Dragon Ball Z, due to being largely outclassed by both his allies (namely the Saiyans) and their enemies, he is always present whenever a new threat approaches, and will occasionally lend a helping hand, thus proving himself to be a powerful ally in his own right.
