Goku fight Metal Koola. Couple of blows here & there. Goku goes SSJ fight some more and look at this Vegeta comes out of no where (This probably be more of a surprise if his name wasn't in the title). Vegeta came in his own space capsule, and he arrives to ensure that Goku lives long enough for Vegeta to kill him himself as always. He goes into SSJ mode. Goku and Vegeta fight Metal Koola together, and get trashed. They get wired into the ship to provide power for Big Ghetti Star. Goku and Vegeta push the limits of their Super Saiyan power, and cause Big Ghetti Star to overheat. Finally, Goku blows the real Koola away, and Big Ghetti Star explodes. Vegeta gets in his space pod and takes off.
