To clear up confusion. Yes. Noah CAN access ui (Ultra Instinct) and mui (Mastered Ultra Instinct) Like I said when I first showed Noah he has every power ever made and thought of meaning that yes Noah CAN go SSJ 1,2,3, SSJ god and SSJ blue but not kioken and not SSJ 4. Which aren't even his strongest forms.
( Also there are characters still coming, I'm just burnt out, after the final main character in the group the rest will be background characters. I simply love to spoil stuff ahead of time :) )
