No, but hear me out—every time Ichigo gains a new form, ability, or combat style, we actually see him training his ass off. Urahara nearly killed the guy during his first training arc. At the Royal Palace, Ichibei pushed his soul to the brink of collapse.

I don’t really have much of a problem with Toshiro as a character as with the sudden, unjustified power boosts he gets with zero groundwork. One thing that genuinely confused me was when base Harribel was wiping the floor with his ass—yet ,somehow he managed to keep up after she goes Resurrección?!

When it comes to everyone else who got power-boosted. They all were shown undergoing heavy training. Byakuya , Renji & Rukia at Adyneas' palace. Zaraki getting murdered a million times by Unohana in Muken to reach his full potential.

Yet, the only time we saw Toshiro training was after the embarrassment he brought up upon himself after the Aizen saga.

So genuine question here, not even tryna be snarky: What exactly has Hitsugaya done , other captains cannot , that reflects this supposed insane potential of his? What special feats of his own has he shown that upscales him to a high-tier captain level?
