Yes this is a show, gohan has no need to prove hiw worthiness to the show hes one of the main characters, even if most of the time hes a g** whining b****, or an over c0cky d***head flaunting the powers he didnt earn at all (mystic) I dont care.
i just dont like kid gohan untill he goes ssj2.
And adult gohan has much more stages, normal, ssj, ssj2, mystic and SAIYAMAN!!! But i pretty much dont like gohan, and downright hated him during the saiyaman saga (does it deserve that title???) and how he acted to videl lying about his powers and the powers of all his friends and pretending hercule was the strongest. I was just egging for vegeta to say "No shut up fool" and punch him through a wall. Id have laughed.
The point of this story is, gohan as an adult would be best cause he has more transformations, a better voice and he looks cooler. And also he is cool in mystic. Just c0cky and arrogant and dumb. But thats much better than any other time with him throughout the series.
So go ADULT GOHAN
