Sōsuke Aizen (藍染 惣右介 Aizen Sōsuke?) is a fictional character and formerly the main antagonist in the anime and manga series Bleach created by Tite Kubo. He is the captain of the 5th Division when he is first introduced, but later betrays the Soul Society and becomes the series' main antagonist until he is defeated by Ichigo Kurosaki and Kisuke Urahara. His former lieutenant is Momo Hinamori.
Aizen spent much of his career in the 5th Division, eventually becoming its lieutenant under the former captain, Shinji Hirako. Aizen also gained followers in Gin Ichimaru and Kaname Tōsen. A century before the series' setting, after Kisuke Urahara created the Hōgyoku, an item that he believed creates Soul Reaper/Hollow hybrids, Aizen began to experiment using the Soul Reapers that became the Visards. Among his test subjects with Shinji, who knew Aizen was up to no good but learned too late that Aizen used his distrust against him. Having also framed Kisuke for the Visards' creation and forced his exile, Aizen learned the Hōgyoku actually grants its user's desires if they have the will to carry it out. But as Kisuke took the Hōgyoku with him, Aizen bides his time to take the item when the time comes.
At some point, Aizen also saw the potential of Shuhei Hisagi, Momo Hinamori, Izuru Kira, and Renji Abarai, and took the latter three into his division, while sending Shuhei to the 9th division under Tōsen. While Kira and Hinamori were obedient and loyal, becoming the lieutenants of the 3rd and 5th Divisions under Gin and Aizen, respectively, Renji proved to be too rebellious and was transferred to the 11th Division (and later to the 6th, where he too became a lieutenant). Aizen also continued his experiments on Soul Reaper/Hollow hybrids with his creations Metastacia and White playing a respective role in the life of Rukia Kukichi and those of Isshin Shiba and Masaki Kurosaki. In the case of Isshin and Masaki, Aizen knew of Ichigo's existence that resulted from White's actions and considered the youth a being worth studying to the point of engineering the hardships he would face later in life.
Sometime prior to his departure from Soul Society, Aizen and his two followers travelled to Hueco Mundo by arranging an alliance with the self-proclaimed god king of Hueco Mundo, Barragan Luisenbarn. As Barragan refused, Aizen revealed all of the Hollow's minions were killed during the discussion and forces Barragan into servitude. From there, Aizen appropriates Barragan's palace Las Noches and reconstructs it in his own image, recruiting Tier Halibel and the other Arrancars that would become his Espadas.
During his tenure as a Soul Reaper, Aizen created a public image of a bespectacled intellectual whose humility and warmth were equaled only by his dedication to the Thirteen Court Guard Squads. However, it eventually became apparent that this was a carefully crafted facade designed to draw suspicion away from his true, sinister nature. Tite Kubo stated in an interview that "part of Aizen's appeal is that he's mysterious," and for this reason he did not think it is a good idea to go too in-depth with the character. In truth, despite his apparent kindness, Aizen sees his subordinates as only pawns and warns them in advance not to trust him. By his own admission, he views morality and empathy as weaknesses which must be expunged in order to reach one's full potential as he is not above killing others to achieve his goals.
During his ascent to Hueco Mundo, Aizen discards his guise by removing his glasses and sweeps a hand through his hair to reveal menacing eyes and a very different hairstyle, telling Jūshirō Ukitake that no one has stood in heaven, not even God himself. He then says "there is an unbearable vacancy in Heaven". Aizen is later shown in Hueco Mundo wearing clothing similar in style to the Arrancars and the Espadas he has recruited. After fusing the Hōgyoku into himself, Aizen becomes so confident that he believes himself to be invincible to any opponent. But when fighting Ichigo after mastering the Final Getsuga Tensho, unnerved by a stronger foe, Aizen discards his calm nature and becomes crazed with rage. His arrogance ultimately led to his defeat at the hands of Ichigo Kurosaki and Urahara. It has been conjectured that Aizen's true objective is to overthrow the Soul King, becoming the new ruler of the Soul Society. As Ichigo later mentioned, there seemed be a hint of sadness in Aizen's reasoning and high level of power, and that his current condition by the time of his defeat may have been the Hōgyoku granting his subconscious desire.
Aizen is an extremely powerful combatant, well above many captain-level Soul Reapers. When preparing to activate the Hōgyoku, he states that despite its half-awakened state, it can be fully activated temporarily when fusing with someone with at least twice as much spirit pressure as an average captain-level Soul Reaper, referring to himself. After Aizen embedded the Hōgyoku into his body, he undergoes a series of transformations that give him extraordinary boosts in both speed and strength.
Originally, Aizen carried a zanpakutō called Kyōka Suigetsu (鏡花水月?, literally "Mere shadow"). Kyōka Suigetsu's Shikai ability Kanzen Saimin (完全催眠?, literally "Complete Hypnosis"), activated with the command "shatter" (砕けろ kudakero?), is effective if the target watches the Shikai sequence once and thus can fall under Aizen's deception any time he wishes. There are only a few means to escape the sword's influence such as touching the blade before it is activated as Gin overheard. Though unaware of that fact, in his gambit to take down Aizen, Yamamoto grabbed the blade when it pierced him and read the blade's force to distinguish Aizen. But after his final evolution by the Hōgyoku, Aizen no longer needs Kyōka Suigetsu itself as the weapon completely dissolves with its powers now a part of Aizen's being after returning to his human state.
Setting up the events from the shadows, Aizen arranged for Rukia Kuchiki to meet with Ichigo Kurosaki so he can become a Soul Reaper. From there, from sending Hollows in Karakura Town to alerting the Soul Society of Rukia's location to get the Hōgyoku that is concealed within her body, Aizen created an elaborate conspiracy among the Thirteen Court Squad captains by secretly killing the members of the Central 46 Chambers and using his Zanpakutō to have an illusion of them sentence Rukia to death. He then faked his death to have Gin play the villain as the captains begin fighting amongst themselves. Eventually, Squad 4 Captain Retsu Unohana uncovered the truth as Aizen removed the Hōgyoku from Rukia's body before he, Gin, and Tōsen escape into Hueco Mundo. There, Aizen begins preparing for his true goal: Using the Hōgyoku to sacrifice the souls of Karakura Town in order to create an Ōken (王鍵?) to kill the Soul King.
From there, Aizen begins to make several Arrancars in his service stronger using the Hōgyoku and sends some of his Espadas to the Land of the Living to gain information on Ichigo. Eventually, claiming to have an interest in her power, Aizen has Orihime Inoue brought to Las Noches on the notion that he needs her to save the powers of the deteriorating Hōgyoku. However, sacrificing the weakest members of the Espadas in the process, Aizen revealed the kidnapping be a ruse to trick Ichigo and his friends into attempting a rescue as part of a scheme to cut the Soul Society's forces in half by the time he enacts his attack on Karakura Town. Though he came with three of his strongest Espadas, the defeat of Staark and Baraggan convince Aizen that surpassed his own minions and strikes Halibel down to deal with the opposition personally. When confronted by Ichigo, who is the only person not effected by his Zanpakutō, Aizen reveals his role in the youth's life and struggles since meeting Rukia. Aizen then almost reveals Ichigo's lineage when Isshin intervened to take over the fight prior to Aizen revealing that he absorbed the Hōgyoku as it grants his desire for a Hollowfication-like form to easily defeat his enemies.
Aizen then makes his way to the Soul Society so that he can create the Ōken, finding Ichigo's school friends and deciding to kill them first before enacting his goal. However, though he expected it but unaware of his right hand's true power, Aizen is fatally wounded by Gin. However, his will to survive answered by the Hōgyoku, Aizen evolved into another form and mortally wounds Gin as Ichigo arrives. Though expecting him not a threat due to his sudden lack of spirit energy, Aizen finds himself overwhelmed by Ichigo's newly enhanced physical strength. Though his fear caused the Hōgyoku to turn him into a Hollow-like monster, Aizen barely survived Ichigo's final attack as he evolved once more to the point he no longer needs his Zanpakuto. However, Ichigo's attack weakened Aizen to the point that the Hōgyoku no longer acknowledges him as he is reverted to his human form while engulfed in a specially made kidō "Seal" that Urahara planted on him. Ten days later, Aizen is sentenced by Central 46 to 18,800 years of imprisonment in the lowest underground prison, the 8th prison known as "Muken". But Aizen's arrogance towards the matter resulted with him being gagged with the sentence escalated to 20,000 years.
Later, when the Wandenreich invades the Soul Society, Yhwach offers Aizen a place in his organization. However, refusing to join his army, Aizen uses his Zanpakuto power to manipulate Yhwach's sense of time before the Quincy realizes too late as he is eventually forced to retreat.
Appearances in Other Media
Aizen appears in most of the Bleach video games, with the most recent ones with him in his post-Soul Society outfit. He also has his own Bleach Beat Collection, a brief CD of character image songs. The tracks are "Shinsen(sometimes translated as Hanabira)", "Kyōka Suigetsu" and a "Voice Message" from Aizen's voice actor, Show Hayami.
IGN commented that the plot twist in the story and the truth about Aizen was "fascinating and interesting" but also criticized it, saying his Zanpakuto's power was "far-fetched" and overpowered, Aizen didn't have any flaws and that his betrayal was "too planned out to be believable." Despite this, the change in mood accompanying Aizen's revelation as a villain was also praised; IGN praised the animators' job at "giving his face this evil thing about it" without changing anything about the animation itself, citing that "the Aizen that we first knew was the nicest guy ever, he looked it, and now this Aizen actually looks like the most evil jerk we've ever seen." Carl Kimlinger from Anime News Network comments that Aizen's revelation as an antagonist is "brutally unpredictable." He notes the violence from that part to be frustrating but in the same time satisfying, praising the large number of revelations. Aizen was additionally noted to have a remarkable development in his introduction as a villain with Kimlinger wondering "If only all villain grandstandings were so thrilling". Theron Martin from the same site noted that this scene makes the anime deserve credits for the biggest “I am a total bastard” moments in anime history." Mania Entertainment's Bryce Coulter noted that such episode "makes you [viewers] want to hate Aizen" due to how he controlled the character's actions in previous episodes and how he now easily defeats most of them. Aizen's English voice actor, Kyle Hebert, describes Aizen as a "mysterious, calm, cool character" and that gives an air of "where does this guy come from?".
