DRAGON BALL (PICCOLO)

A wise and cunning warrior, he was the main antagonist in the final saga of Dragon Ball, the Piccolo Jr. Saga, and was thus a ruthless enemy of Goku. However, starting with the first saga of Dragon Ball Z, the Raditz Saga, he began to lose all villainous traits, and when he started training Goku's son Gohan during the Vegeta Saga which led to the two developing a strong bond, he became a permanent member of the Dragon Team and eventually one of Earth's greatest heroes.
