#14 & 15 lead the attack which made Goku & Future Trunks go to the north glaciers so no one would get hurt. Gohan & krillin went to go follow them. #13 began to fight Goku while Trunks fought #14 & 15, until Vegeta got there and he fought #15. After a little bit of fighting they all went SSJ. Gohan was going to help him as #13 tried to blast the half saiyan boy, but the blast was destroyed by another ki blast. Gohan yelled out Piccolo's name. Piccolo shows up tunneling through the ground with aloud noise. He pops out of the ground, grabs #13's legs and throws him toward the ground. After #14 and 15 are destroyed, #13 absorbs their power cells to undergo a powerful transformation (sounds like Cell to me). He now became Super 13. Vegeta goes SSJ and rushes at the enemy and told Goku and Piccolo not to interfere. Vegeta gets beated down. Piccolo was next to take a crack at him and got blasted away. The only way #13 can be destroyed is for Goku to create the Ultimate Spirit Ball, instead Goku absorbed the energy and went into SSJ mode. Goku is completely powered up, a large ball of energy surrounding him. He's crushing everything in his path! #13 tries to attack him futilely. He screams as Goku punches a hole in his stomach. Then the android is destroyed.
