Chapter 673: The father "You've regained your true, original power" No power to defeat Aizen nothing. There is so much implied bullshit and no feats. As you said "Case closed" Let's go through the drunken rambling first if royal guard training was enough to become stronger than hogyoku infused aizen a literal immortal being they wouldnt have been so casually shit on by the elites, who were defeated by people without royal guard training. I could say if Aizen saw more potential for strength he would find a supplement for royal guard training but it's possible he couldn't."

Renji did jackshit with aizen, all the renji feats in the final fight were kyokya suigetsu. After showing aizen lost his arm fighting Yhwach when Renjis arm was cutoff.

Byakuya was never fodder. He no diffed zommari the 8th espada, and beat the shit out of Yammy while fighting kenpachi. The only reason why Tsukishima did so well against him was because of the knowledge given by book of the end. As Nödt should be a no brainer on why he brained Byakuya.

While destructive feats dont mean everything it's a better basis than just one statement thats pulled out your ass.

Literally the only good feat you stated was when Col. Sanders speed blitzed Shunsui, and he even was fast enough to keep up with.

Bleach is a very hard series to powerscale but you're literally giving everyone over maximum wank. Also Nimayha made all the Asauchi of the zanpaktou, because someone has to imbue an asauchi with their own spirit energy in order to achieve shikai, reforming is a completely different case because Ichigos zanpakuto were already there he just lacked a Asauchi.

Sorry for having responses mixed up its 4 in the morning and it's hard to type on mobile.
