"It's hard not to see his various rivals as shipping analogues. Hell, TFS did a whole short that was basically about that. Vegeta is to Goku in terms of rivals what Chi Chi is in terms of actual relationships: the old faithful that stays with him even after all the passion has died because it's easier to stay together than it is to find someone else.
Props to Goku, he seems to have realised this and been making steps to find new people, even if it's had mixed results. He had a good thing going with the cute, unconventional assassin from Universe 6, but didn't realise what he had and squandered it to chase after the bitchy head cheerleader from Universe 11, who won't give him the time of day because he's *so* out of her league. He's also fallen into a bad way trying to reignite the flames with an old one-off, the galactic tyrant. A toxic relationship with an awful person who caused nothing but pain, but still Goku will never forget that wild, passionate evening on Namek. Sure, she acts like she's ready to turn over a new leaf and try for something long-term, but let's face it, Goku needs to see the writing on the wall.
He's also tried grooming his own rivals, taking kids with potential under his wing. It didn't work out with his two sons, so he's ended up doing it with a pair of girls half his age and a little African boy. And that's where this analogy gets creepy(er)."
