| “ | From the very start, no one has stood upon the heavens. Not you, not I, nor even gods. However, that intolerable vacuum has come to an end. Henceforth...I shall stand upon the heavens. | „ |
| ~ Aizen addressing the gathered Shinigami and Ukitake personally |
| “ | Fear is necessary to achieve evolution. The fear that, in one's current state, one could quite possibly be destroyed at any time. I thank you, Gin. It is thanks to your presence that I have finally succeeded in surpassing both Shinigami and Hollows | „ |

Background
Sōsuke Aizen (藍染 惣右介, Aizen Sōsuke) is the former captain of the 5th Division in the Gotei 13. He later leaves Soul Society with his followers, Gin Ichimaru and Kaname Tōsen after betraying the Soul Society. His lieutenant was Momo Hinamori. He was the leader of The Espada. After waging war against Soul Society with an army of Arrancar, Aizen was defeated by Ichigo Kurosaki and sealed away by Kisuke Urahara, and then imprisoned for his crimes.
Much later, Yhwach goes back to Soul Society, and Aizen welcomes him to his Soul Society. Yhwach destroys Aizen's chair, releasing him of his bindings, and Aizen remarks on the amount of trouble Ichigo gave Yhwach in combat up in the Soul King Palace. So he works with Ichigo, Renji, and Uryu to work together to defeat Yhwach.

Immortality and regeneration also make him hard to kill) | Low Macroverse level (More durable than before. Survived Ichigo's Mugetsu due to the Hōgyoku) | Low Macroverse level (Took attacks from Post-Power Absorption Yhwach)
Stamina: Extremely high | Nigh-unlimited with the Hōgyoku
Range: Extended melee range with physical strikes, tens to hundreds of meters with various Kidō spells (some of his Kidō blasts have been shown as dwarfing entire city blocks), hundreds of kilometers with Fragor and Ultra Fragor, thousands of kilometers with Hadō #90: Kurohitsugi during the Thousand Year Blood War Arc.
- Hōgyoku: A powerful object originally created by Kisuke Urahara. Once equipped, Aizen is granted the ability of high-speed regeneration, and constant evolution in the form of more powerful transformations. However, should he be pushed beyond his limits, the Hōgyoku would backfire on him and no longer consider him to be the true wielder of the Hōgyoku.
- Caja Negacion: These cubes are capable of sealing away an enemy from the battlefield for a very long time, even foes that are far stronger, however the time limit for the stronger foes is much shorter than those on the same level as him.
- Reiatsu Concealing Cloak: A cloak created by Urahara which hides the wearer's Reiatsu. Aizen used this cloak to sneak up and attack Isshin Shiba. Aizen states it allows the wearer to blend in with the air around them by incorporating Kidō into the cloak, almost completely concealing them from sight.
Intelligence: Extraordinary Genius. Arguably, the most fearsome trait of Aizen is his tremendous intellect. He is well-versed in the history, strategy, and tactics of Soul Society, and is privy to knowledge unknown to many, such as the existence of the Ōken, as well as the obscure method in which to create one and Ukitake being the host of the Mimihagi. He has created several Hollows and Arrancar while avoiding arousing any suspicion from the majority of his fellow Shinigami. For over 110 years, he had been engaging in experiments which involved unique and highly dangerous manipulations of Reiryoku and Reishi, including experiments involving the Hollowfication of Shinigami, something which had never been done before. He has an innate knowledge of the Hōgyoku, rivaling that of its creator, Kisuke Urahara; he even knows how to destroy it. He figured out the true nature of Shinji Hirako's Shikai, deducing that it creates an optical illusion that alters the targets sense of direction, and after just one exchange, he could adapt and fight with not only his sense of direction but his eyesight, and the direction of incoming attacks reversed, stating to Shinji it was mere "child's play". He effectively deduces the true nature of the Hōgyoku via trial and error of the situations which revolve around it. He was also aware of several events, which happened in separate dimensions, as he knew about Ichigo fighting and winning against Grimmjow and Ulquiorra, while simultaneously awakening a "new power", despite being in the Real World with the Espada at that time.
Weaknesses: Before EoS his Zanpakutō's special ability can be overcome by touching its blade before it is released, and he is somewhat overconfident. He can only use his Reality Warping when possessing the Hōgyoku.
Notable Attacks/Techniques:
- Shunpo: A Shinigami movement technique which allows the user to move faster than the eye can follow. As speed is the main factor of the technique, the method is best characterized by how fast one can get from point A to point B in the least amount of steps.
- Shikai: The initial release to a Shinigami's Zanpakutō. It is activated by a command while declaring the name of the Zanpakutō Spirit. It changes the shape of the Zanpakutō and/or granting special abilities. Aizen's Shikai is Kyouka Suigetsu, released on the command "Shatter".
- Perfect Hypnosis: Aizen can control the 5 senses of his opponents with the Shikai of his Zanpakutō, who'll be completely succumbed to the Hypnosis once activated.
- Bankai: The ultimate and final release to a Zanpakutō. The difference in power between Shikai and Bankai is generally around 5-10 times more powerful. Even though Bankai is the final stage of a Zanpakutō, it does not mean the Shinigami's growth ends there. A Bankai, especially one recently obtained, can evolve even further as its Shinigami gets stronger. Aizen's Bankai is unknown.
- Fragor: Aizen concentrates a large amount of Reishi into one of his wings and fires it upon his foe for a massive AOE strike.
- Ultra Fragor: Aizen grabs his foe and surrounds them with his six wings, each part of said wings charges up their own Fragor to imprison the foe with the power of 6 Fragor.
Kidō: Spells cast by Shinigami with strong enough Reiryoku and Reiryoku control. Kidō is divided into mainly three categories: Hadō for attacks, Bakudō for battle support and Kaidō for healing. The spells are ranking from 1–99 with 1 being the weaker and easier spells to cast and 99 being the most powerful and difficult to cast. Skilled users can cast Kidō without the need of an incantation; however, casting without incantation does reduce the Kidō's effectiveness less than a third of its full potential.
- El Escudo: A light green Reiatsu barrier that Aizen can summon around his person to block an incoming attack.
- Millón Escudo: An advanced form of El Escudo, Millón Escudo is simply a million El Escudo that Aizen can form around any part of his body for even greater protection.
- Bakudō #26: Kyokkō:A spell that bends light in order to hide the caster, their Reiryoku, Reiatsu or their Kidō.
- Hadō #63: Raikōhō: Lightning Reiryoku is gathered into the caster's arm and released towards the target like a shock-wave.
- Bakudō #81: Dankū: Upon activation, the caster generates a barrier that is capable of the complete nullification of any Hadō of the level 89 or lower. However, this barrier is not solely limited to Hadō as it can nullify the effects of abilities that are similar to Hadō.
- Hadō #90: Kurohitsugi: The target is sealed inside a large black coffin and are seemingly cut while inside. A large torrent of gravity is located inside that distorts space and time while restricting any chance for escape.
- Hadō #99: Goryūtenmetsu: Five large pillars of light are generated around the caster composed of Reiatsu that resemble large dragons. A forbidden Kidō as it not only destroys the surroundings, it absorbs nearby Reiatsu to enhance itself.
