1- That he explains or shows how on earth is Piccoro keeping up with them on the tournament. Make him turn a super namek, make him train 100 years on the time room, make him gain a power like ultimate gohan did, and then we can talk. Even this fodder gohan is > current piccolo
2- Gohan comes back as the great warrior he is.
3- They must stop making the earth warriors looking like trash
What he is doing?, the same thing gohan wanted to do since his childhood. Become a scholar/scientist, if you seen dbz then you see gohan never aimed to be a warrior.
Gohan should be training so when shit hits the fan, he can protect his family without having to rely on daddy but i guess following his "Dream" which chichi drilled into him is more important than his family and everyone on earths lives.
I still hold hope that gohan was purposely left on earth because something is going to go down and he will redeem himself but as a gohan fan i'm finding it hard to like his current state
Most don't care about character just his power. As a kid I loved that he'd step when he needed to but he never seemed to like it like goku did when he was young. I would love to have seen how he would've grown up in a time of peace to see if he would've taken after goku or chi-chi as far as what they wanted for him.
