Goku is in SSJ3, and Vegeta in SSJ2.

Vegeta: Teleports in front of Goku. Kakarot, I'll make my stand against him, you power up!

Goku: Alright, let's do it. Goku explodes his Ki and floats up in the sky, as he rips off his Gi and starts to charge the Spirit Bomb.

Vegeta: Come at me, I will not let you go on like this! He got in his battle stance, ready to battle you.
