I've always been a fan of GokuxVegeta, but what do I know.
I mean, uh, Gohan was a letdown throughout the series. Every time he seemed to shine, he screwed up. Thanks, Gohan, for getting Mirai Trunks killed when you could have killed Cell. Thanks, Gohan, for getting eaten by Buu when you were so mystically empowered. Et cetera, et cetera.
