Goku completes the Spirit Bomb and hurls it down upon Frieza. The tyrant manages to catch it, but is unable to stop it from exploding on him. The Z Fighters celebrate their apparent victory and start making plans to return to Earth. However, Frieza reappears and, though badly damaged from the Spirit Bomb, he is still powerful enough to take them all out. Frieza fires a beam straight at Goku, but Piccolo jumps in the way and takes the beam to the chest, which knocks him unconscious. Frieza next sets his sights on Krillin and causes Krillin's body to explode from the inside, killing him. Enraged by these sacrifices, Goku undergoes a radical transformation in which his eyes turn from black to green, his black hair turns gold, and his body is surrounded in an aura of golden light. With his powers now greatly enhanced, Goku orders Gohan to take Piccolo to his spaceship, find Bulma, and leave Namek, while he handles Frieza.
