I donβt have any good examples that I know of, but I am very curious. To me though, a rivalry is a rivalry when two or more of people are closely competitive. But is it really a rivalry anymore when someone has more victories over the other? I donβt think so.
Especially if you also consider the abridged version but gokou and vegeta also a good example.
Kakarot just treats Vegeta like a freind, and Vegeta will never think of Gokou as someone he has to surpass and maintain some kind of supremecy over
