And that's before he starts getting crazy power boosts from mastering his Inner Hollow abilities. Given that most Shinigami take ten years to learn how to manifest Bankai, and another ten to master it, the fact that he learns within two days how to use his effectively enough to match one of the strongest Captains, even with an advantageous matchup, is nothing short of terrifying.

Ability Mixing: Ichigo's 'Lost Agent' Shikai and Bankai are the result of the remnants of his Fullbring amalgamating with his restored Soul Reaper powers, making him stronger than he was previously.

His Bankai is Tensa Zangetsu, originally a slender pitch-black katana which compresses his vast power within his body, allowing him to perform combat at blinding speeds and with greater strength. This weapon is destroyed by Yhwach, and subsequently reverts to its original appearance. After obtaining his own Asauchi, it changes to two blades, one of which is large and the other of which is a smaller, arm-length blade. It allows him to condense his spirit energy at the tip of the blade and blast it all at once at his enemies - a technique known as Getsuga Tenshou. His Zanpakuto is Zangetsu, which was originally a large blade created by his fusion of Hollow and Soul Reaper powers.

He has the ability to gain many different kinds of powers, but because they interfere with each other, his competence level fluctuates until he is able to resolve the issue. His growth rate is phenomenal, quickly allowing him to surpass even talented veterans. When Soul Society retrieve the AWOL Rukia, Ichigo learns she will be executed due to it being illegal for Soul Reapers to imbue humans with their power, so he begins an assault on Soul Society to save her.

When Rukia gives him Soul Reaper powers, she's shocked by how quickly his abilities eclipse her own and forces him to assume her duties while she's powerless. The hero of the series, sarcastic and grumpy, Ichigo originally attempted to cultivate a tough guy image to hide his sense of powerlessness at being unable to protect either people or the spirits he can secretly see.
