Ight I got one:
"What if Goku had One Punch Man syndrome but wasn't a fighter?" (but he keeps his hair)
Every fight just ends in a punch... but he doesn't want to fight, in fact he hates it. He nearly dies during incubation that this state kept powering up his soul so much that he has become all powerful and constantly gets stronger from just existing.
Goku grows up doing martial arts with Gohan but not because his body craves it but rather as a means to bond with Gohan. Goku's hobby is reading books and eventually convincing Gohan to get a tv so he could learn more about people.
But then Gohan dies, as Goku mourns him by keeping up with his training even if he doesn't need it just to remember his kind grandpa.
So eventually he meets Bulma and intimidates Yamcha by nearly killing him with a punch.
Soon after he rejects ChiChi's offer and says that doesn't see her that way. He then copies the kamehameha to an insane degree and gets offered by Roshi to get trained.
He destroys everything Pilaf has to offer who tries to blow up the castle but Goku literally just grabs everyone and yeets.
So they have all 7, and Bulma wants Goku to have the wish and so he wishes to know who his parents are. After finding out he's an alien from an extinct race, he suddenly flies away and lets it sink in for awhile. When he takes up Roshi's offer he just... reads whatever books are in Kame house.
He's not a math nerd like his son, but he's interested reading stories and having his mind challenged.
He helps Krillin recruit Launch as he finishes his last book, challenges Roshi and beats him before bowing at the semin shicked old man.
He tells Roshi that his body is trained but his brain is weak and that he'll try to seek knowledge, Roshi approves and they leave on good terms.
He flies into the city where Bulma lives and asks if he can live in the city too... just because he is all powerful doesn't mean he just wants to fight and wants to experience a city life just like the soap operas.
She's actually surprised that she got Goku... wrong and realized he's actually a deep person.
So he lives at CC and goes to school and tries his brain as hard as he can despite being so far behind academically.
Eventually he gets wind of the tournament and goes hoping to see Roshi and Krillin and Launch with Bulma tagging along...
