seen this au floating around? but from the japanese fanbase. Looks like if Bardock had managed to save the Saiyan race. Goku/Kakarot ends up being Vegeta’s right hand.
Though Kakarot helps defeat and conquer and/or destroy neighboring planets, he still seems pretty dense and he still has a thirst for fighting the next big foe and is really good at it. I suppose that’s just my interpretation of it tho
