The whole purpose for Yamato staying and not living her dream.I mean, if his bite can hurt Kaido, he can definitely hurt them too
Just that Momo's also the epitome of "strong and unskilled" at the moment
Which means he's technically their tier in raw stats, but that won't matter at the moment in a straight up fight
I'm sure he'll actually have some training by his next appearance though (and let's be real, we know he'll appear again), so that'll probably change
