Son Goku, Kakarot

Here lies a world in which Goku retains the memories of his final moments before leaving Planet Vegeta; Grandpa Gohan, subsequent to dropping Goku, has a senzu bean gifted from Muten Roshi. He gives it to Son Goku, who keeps more of his sense of identity. This only drives him to gain a deeper understanding of himself. One small change couldn't be that drastic, could it?
