I’ll be honest with you, I’m still shocked, no pun intended, that Choijiro was able to pierce him, crazy.
Back in Bleach Asylum, people said that Choijiro scarring Yamamoto with his bankai was an antifeat, rofl, Kubo btfo’d them in the most unexpected way.
Yhwach being weaker was a headcannon, just like the whole BS about him being able to use other quincies power, and him becoming stronger after every death, people dying only served the purpose of memories and keeping Yhwach from regressing to his disabled self.
Hashwald, clearly says so, the Yhwach that fought Ichibei is the same that was pierced by Choijiro:
It’s impressive that Yhwach was still able to reason after 990 years in this sorry state, regardless, wanna know who actually was weaker?
Yep, wristS, in my opinion, Kubo had an arm loss fetish, and had to rationalize it to his readers, but yeah, losing an arm, makes you weaker reiatsu wise.
Funnily enough, Aizen would end up as the SWP of reiatsu, after we’ve seen Yhwach chastising Yamamoto for not healing his arm, and due to that, not making it as a SWP.
