This not a versus thread.
Goku and Naruto
Their parents were killed protecting them and others. Pretty much all their friends hated them the first time they met. Main characters(of course lol). Naruto's clan was pretty much wipe out with the exception of few. Goku's race was wipe out with the exception of a few. Both eat a lot. They both put the world in danger because of who they are. Goku was known as the savior of the universe so he had put many in danger. Naruto has the Nine Tailed Fox inside him a put his entire village in danger. They considered their rivals good friends.
Pretty sure there is more to these two but can't think about it.
Vegeta and Sasuke
Their race and clan was wiped out by people they thought they can trust. They are the rivals of the main characters. They both have or had hatred in their hearts. Vegeta turned over a new leaf. It seems like Sasuke is turning over a new leaf too. Who knows what Kishi decides to do with Sasuke.(Besides Kishi)
Some might not agree with this next one
Ginyu Force and Rock Lee and Guy
Not saying Lee and Guy are evil though. Just saying their actions are kind of the same. Their all goofy.
Roshi and Jiriya
I dont think i even have to explain this one.
If I missed any I'm sorry.
