Bora gives Goku the 4-star Dragon Ball. The RRA sends the assassin Taopaipai, who kills Bora and severely beats Goku. Goku climbs the Karin Tower to become stronger. He meets Karin, a hermit cat, who makes him drink the Super Holy Water (which is not actually poisoned but makes him believe it is to push him to train). Goku easily defeats Taopaipai and destroys the RRA base. Commander Red wanted the Dragon Balls to become great; in a fit of rage, Adjutant Black kills him with a bullet. Goku destroys the RRA and obtains 6 Dragon Balls.
