Goku in equestria

Goku and bills were battling on a catastrophic level goku would punch forward and bliss would doge and did a round house kick to goku's face. In the last three years goku had been training and can transform into a super sayain god at will but it only lasts 30 mins. Goku had three minutes to kill bills so goku did a very risk thing he power to max and did a full power super kamehameha it killed bills but goku did not know was that a portal had opened up and he was flying towards it at full speed. Before he could react he was sucked in the portal only for it to close behind him and mere to open again. All the z fighters were searching to find goku for two hours and they were losing hope to find him. He was no where to be found so they stopped the search presuming goku was dead but they all where wrong.
