Barragan, the God of Death, whose power ages anything to dust. His fight against captain-commander Yamamoto’s lieutenant, Sasakibe, is iconic. Season 11: The Zanpakuto (Episodes 206–212) Arc: The Past Arc (Turn Back the Pendulum) – CANON Key Episodes: 208 ("Aizen and the Genius Boy")

Part 1: The Blood Warfare (Episodes 367–392) Arc: Thousand-Year Blood War (Invasion) Key Episodes: 376 ("The Battle of the Last") Barragan, the God of Death, whose power ages
A bizarre but beloved filler arc where the Zanpakuto spirits (sword ghosts) rebel against their Shinigami masters. We see Zangetsu as an old man, Hyorinmaru as a dragon, and Zabimaru as a baboon-snake. It’s pure fan service. The animation is movie-quality

Aizen’s monologue about standing at the top of the heavens is chilling. Season 12: The Decisive Battle (Episodes 213–229) Arc: Fake Karakura Town (Conclusion) Key Episodes: 219 ("Hitsugaya's Resolve! The Moment of Fierce Fighting")
Back to canon. Aizen’s army of Arrancars descends on Karakura Town. Ichigo meets his rival: the feral, blue-haired Grimmjow. Most importantly, the Visoreds arrive—former Soul Reapers who gained Hollow powers, led by Shinji Hirako. They offer to train Ichigo to control his inner Hollow.
