First, Goku must fall to whichever planet seems the most like earth in this universe, and then The Doctor breaks the space time continuum and accidentally brings star trek’s baddies, as well as his own enemies, into the Star Conflict universe. He then contracts captain James T Kirk to help him hunt them down. Everyone from the Dragonball /z/gt universe appear in their fully powered up states to defend the home planet against all sorts of enemies. Consequently, Dr. Gero builds the androids and Cell within this time. Before the Androids awaken, Cell is completed and absorbs with the two androids. In the end, Gohan, Goku’s son, kills cell without a single loss of life on the Z fighter’s side. They then go to Namek and make three wishes from Namekian dragon. Wish No. 1: That all humans killed within the year that cell was rampaging would be brought back to life.
- that they would all become immortal. 3. that they could all live in space without having to breath.
Thus Goku and friends used instant transmission and went back to their home planet in the Jericho sectors. Seeing that Jericho is having trouble fighting the large amounts of enemies in the federation and mainly the empire, Goku releases a spirit bomb the size of the sun into the front lines of the Empire’s home sector. It exploded with the force of a thousand suns, and its power level was definitely over 9000.
Being very sneaky, frieza suddenly finds all of the dragonballs and wishes that everyone that was killed by Goku and friends would be brought back to life. All of them, having had their lives smothered from the universe, decided that they would all aid Goku in his quest to destroy the Empire and Federation. Thus, the rampage begun.
Later, the Doctor accidentally breaks the space time continuum again, and all of the dc and marvel universe’s heroes/baddie heroes spill through the rift thinking goku is an enemy
He takes out the hulk first by throwing him into a black hole with instant transmission, and then he suddenly appeared back on the battle field and took out half of the dc/marvel heroes in the blink of an eye.
Now, he powers up to super saiyan from no 4, and then fuses with vegeta in his own super saiyan 4 form. Thus, They take out superman before he can regenerate his limbs previously taken by the first blast.
The rest of them are all destroyed.
Suddenly vegeta/goku hear a roar, it would appear that the hulk ate the black hole, and all of its contents, and somehow drifted into a wormhole back to earth. Goku/Vegeta then takes him out in one blast of a Super Kamehameha wave. It left not even a single cell in the hulks body. He is dead.
