The fact that Gohan needed to go Ultimate to defeat Jimeze speaks good of him
And I mean, Freezer could take out almost every contestant that fast if he wanted to. Frost got lucky he got the long treatment
Frieza was in base and not even golden. Gohan didn't need Ultimate to defeat Jimeze. He just needed to counter IT, which he couldn't do.
Let's be real, this is Dragon Ball. 95% of the main cast were evil or an antagonist at some point down the line. They'll forgive it when U-7 saves all their worlds with the wish.
What does that have to do with the other universes since they're not U7?
