I don't wanna be that guy but we're probably not gonna get any new extreme units

I can't think of any extreme unit with the exception of majin vegeta that fits under family or rivals, and he's gonna work better with super units than extreme units.

Sad for us extreme unit lovers, but I think that unknown randoms like super vegito and gogeta, ssj3 goku, and blue evolution are enough to keep me happy, just barely though.
