The Greatest Surprise.While 17 is distracted by making his energy ball, Goku sneaks up from behind and grabs him. He tries to blow them both up, but when the smoke clears, both of them remain alive. 17 had put up a shield to protect himself, but it also protected Goku just enough to keep him alive. Once again, he gathers energy for his final attack, but suddenly 18 shows up. Her taunts cause 17 to turn and destroy Dr. Myuu. He turns back to kill Goku, but before he can, 18 starts firing energy blasts at him. While 17 is absorbing the blasts, Goku realizes that he is unable to move while absorbing energy and thus vulnerable, and he quickly attacks, punching a hole through him. He finishes 17 off with a Kamehameha wave. Bulma arrives, saying that the Earth is incredibly unstable because of the interdimensional portals that 17 and Piccolo opened up. They gather the Dragon Balls to fix this, only to find that they are all cracked. When they call Shenron, black smoke issues from them, and a mysterious but powerful, evil new dragon emerges.
