Gohan. He can destroy planets.
It is basically asking whether enthusiasum or technology would win Mew is the one that even though it can fight chooses not to and so it is almost certain that mewtwo would win, but if mew were to fight back in full force then mewtwo would be hard pressed to win, so overall it could be a draw.
it would be a tie
Vegeta would beat Gohan in any fair fight (i.e. SSJ1 vs. SSJ1, etc).
SSJ2 teen Gohan pwn Broly but in movie 10, he wasn't SSJ2, he was in MSSJ.
