in my reality yamato gets impregnated by ace, becomes a mother which gives her a better background to relate with oden and the fact of momo's being parent-less, motive to go against her dad has to make a better future for her kid and the nation overall.
And cut the mythical zoan bloating the DF catalogue she's a pure haki user, which shows a better version of kaidou "haki trumps all" mentality, the daughter he mistreated all those year having more weight in being a pure haki master without a DF which in a scenario where she manage to go toes to toes against him making him doubt himself more or fight harder because the concept of his mentality being used against him and potentially beating him makes him mad.

all that also because i like a reality where this bitch get's fucked straight and pumped baby batter into. milf oni !
