Appearance

When he was a member of the Gotei 13, Aizen appeared as a mild-featured man with brown scholarly hair enhanced by square glasses, along with soft brown eyes. He wore the standard Shinigami uniform with a captain's haori.[3] During his ascent to Hueco Mundo, he removed his glasses and swept his hand through his hair, revealing menacing eyes and a very different hairstyle; his hair is now swept back, with a strand hanging down his face.[4] In Hueco Mundo, Aizen initially wears Arrancar style-clothes over his shihakushō.[5] After Orihime Inoue is taken to Las Noches, Aizen wears full clothing similar in style to the Arrancar, complete with a pink sash around the waist.[6] Upon his defeat by Ichigo Kurosaki, Aizen loses all of the physical changes made by his transformation and returns to the physical form he had prior to transforming.[7] While imprisoned in Muken, he wears an almost entirely black outfit with white trimming, a large black eyepatch over his right eye and black boots. A tattered white rag is wrapped around his shoulders.
