Gokai is Gohan's unknown twin brother, he is more powerful due to the fact that he trains more than Gohan. His master
is Vekau, his training has made him a Super Saiyan because the training was so hard that he would bleed so much he would steam and one night he had so much pain he went super saiyan and blew up a planet. In the picure of him he is in his strongest form at age 17 know as a ssj3 but without that much hair. He has a rival named Evil Gotanks but tends to play and fool around with him.
