damn can really appreciate one punch man a lot more, this really emphasizes their relationship the blonde dude is his acolyte fanboy and he's perfect for it because he'll give it his all and nearly die, then one punch man comes in and saves him, so he knows he can always stat check the enemy at least and see for himself how much the world would rely on one punch man
if he has the ability to imagine and it happens if hes using that to attack then he could imagine kenpachi heart exploding or imagine there are infinite versions of him thinking different attacks all at once
you gotta give it to kenpachi, even without knowing his zanpakutos name he was still stronger then the majority of them and once he learned bankai well excluding ichigo he was the strongest soul reaper without a doubt (yamamoto is dead so dont say him)
