|~ Sōsuke Aizen|
Sōsuke Aizen is an antihero throughout most of the story of the anime/manga series Bleach. He is a Shinigami who wants to acquire unimaginable power.
Aizen spent much of his career in the 5th Division of Gotei 13, eventually becoming its lieutenant under the former captain, Shinji Hirako. Shinji kept Aizen under his view during this time because he felt there was something dangerous about him. 100 years ago, Aizen's experiments on Shinigami/Hollow hybrids involved using an unknown method to cause spirits to transform into Hollows, eventually culminating in the creation of the Visoreds. He framed Urahara for the hollowfication process and forced him to leave Soul Society.
During that time, Aizen met Gin Ichimaru and Kaname Tōsen, and lured them to his side. Aizen became captain of the 5th Division later on.
When Ichigo Kurosaki and his friends invade Seireitei to rescue Rukia Kuchiki from execution, he manages to lay hands on the Hōgyoku with an elaborate plan involving Rukia's execution and the attempts to rescue her, manipulating most of the other captains of Soul Society according to his will. After obtaining the Hōgyoku, he declares his intentions openly.
The principal antagonist of the series, he resides in Hueco Mundo together with Ichimaru and Tōsen, commanding an army of Arrancar and Hollows, his ultimate goal being to overthrow Soul Society along with the Soul King and take his place as god of the world.
Powers & Abilities
- Monstrous Spiritual Pressure: Aizen possess powerful spiritual pressure, which is strong enough to destroy those with less power. It is so powerful it can stun his opponents and induce fear/psychological damage to victims. It can even create pain to opponents think they've been damaged even though they are not. He claimed that his spiritual power is stronger than the entire Espadas and much more stronger than an average captain-level Shinigami.
- Incredible Reiatsu Control: Marechiyo stated that Aizen's mere presence is ridiculously overwhelming. His Reiatsu is so strong that it can send Grimmjow to his knees with little effort, to the point where he stated that his spiritua; pressure can destroy the entire Soul King's palace as well as the Soul Gate if he wasn't restrained. His Reiatsu is also strong enough to send Shinigamis backwards just be releasing it. His Reiatsu can also nullify abilities, can be used as a shield that can vaporise low level beings metres away and can break through extremely dense shields that are permeated with Reishi just by focusing his Reiatsu.
- Highly Intelligent: Aizen has shown multiple times his strategic prowess. He is a master of deceit, seeing how he framed Kisuke Urahara for his Hollowfication experiments on other members of the Gotei 13. Even without using his illusory powers, he can easily manipulate others. He's more than capable of leading his own army. He is also the ome responsible for the creation of Arrancers and Visoreds.
- Healing Factor: Aizen can heal injuries thanks to the Hogyoku. His healing factor allowed him to heal his destroyed heart.
- Shunpo (Flash Step): He possesses one of the fastest versions of this technique. He can move at enough speed to be considered undetectable. He can easily outmanoeuvre some of the fastest characters in the series.
- Kidō: Aizen is one the most powerful Kidō users in all of Soul Society. Even without the full incantation, his spells can incapacitate Captain-Level Shinigami.
- Enchanted Flowers: Can stun the enemies by casting an illusion of flowers.
- El Escuda: Aizen summons a transparent barrier to block an attack by raising his arm.
- Millon Escudo: Summons a light greeen barrier that is a shape of a hexagonel, which is fixed in one central area. If inactivated, it will remain invisible and upon contact in attack mode, it absorbs energy and disperses it.
- Bakudō #26: Kyokko: Aizen bends light to hide his Reiatsu and his physical form.
- Hadō #63: Raikoho: Shoots an orb of lightning above Aizen's palm, and builds up energy ready to fire at the foe with a devastating lightning attack.
- Bakudō #81: Dankū: A defensive wall is created to protect against an enemy's attack. It is strong enough to withstand strong spell attacks.
- Hadō #90: Kurohitsugi: Aizen's signature spell. Kurohitsugi is a high-level Kidō which seals its target in a black spiritual coffin. If the full incantation is pronounced, the spell has the power to distort space and time.
- Hadō #99: Goryutenmetsu: Aizen proceeds to have the ground rise up in pillars, rising the air that takes the form of a massive dragon made out of air.
- Immortality: After his exposure to the Hōgyoku, Aizen can heal from any wound and can be considered immortal.
- Master Swordsman
- Master in Unarmed Combat
- Immense Strength: He can easily stop other Shinigami's Soul Slayers and knock them out with little to no effort.
- Hōgyoku: Orb composed of a unique substance thought to have been capable of dissolving the boundaries between Shinigami and Hollow, allowing one race to attain the powers of the other. However, its true power lies in its ability to sense the hearts of those around it and materialise their deepest desires.
- Reiatsu Concealing Cloak: A cloak that hides the wearer's reaiatsu. It also allows the wearer to blend in with the air around them by incorporating Kidō into the cloak, almost completely concealing them from sight.
- Kyōka Suigetsu: His Soul Slayer takes the form of a katana. Aizen is highly skilled at using it. It can activate its secret ability by releasing it.
- Shikai - Complete Hypnosis: Aizen uses it to fool others into believing what Aizen wants. It can cast powerful illusions, like decoys. After seeing the sword's release just once, this person will completely succumb to the hypnosis. Afterwards, every time it is released, this person will fall under the thrall of the hypnosis. The hypnosis is so powerful that even if they knew they are trapped under an illusion, Aizen will have free will over their five senses and have no escape. It also has addition abilities ranging from making people attack copies, seeing copies of themselves and making them unable to determine fried from foe. It's also long lasting as it lasted for 110 years on the Visored.
Aizen takes on different forms depending on how much has the Hōgyoku assimilated him.
In this form, Aizen undergoes a huge buff in strength and durability, while also gaining a healing factor.
Second Fusion (Chrysalis)
After suffering heavy damage from an attack, the Hōgyoku gives him a new form with even bigger buffs in strength, durability, speed, regeneration and spiritual power.
Third Fusion (Post-Chrysalis)
Once he breaks out from his chrysalis, he gets yet another increase in power and spiritual power. If a regular human touches him while in this stage, they will vanish from existence.
Fourth Fusion (Trancendent Aizen)
After Gin nearly killed him, he gains yet another form, this one resembling some sort of butterfly. Aside from the obvious strength and regeneration power increases, he gains a new, faster, form of teleportation. In this form, his sword swipes are strong enough to heavily damage the environment around him.
Final Fusion (God Aizen)
After Aizen is struck by Ichigo, the Hōgyoku forces another transformation upon him, which Aizen claims occurs because it does not want him to lose to a human. In this form, Aizen takes on a distinctively Hollow-like form. Aizen retains all previous buffs and gains two new abilities.
- Fragor: Aizen can release bluish-purple energy spheres from the Hollow-like skulls on the top of his wings. A single blast is strong enough to create a large crater and is accompanied with a shockwave which can be felt miles away. It's also stated that it's more powerful than a nuclear warhead.
- Ultrafragor: Surrounding his target with his wings, Aizen uses the Hollow-like skulls atop his wings to generate a circle of spiritual energy around a target. Upon creation, the ring reverberates with power and solidifies, while forming three more larger solid rings in concentric formation.
