Sosuke Aizen is the primary antagonist of Bleach by Tite Kubo. He was the captain of Squad 5 in the Gotei 13, revered by his subordinates as a gentle, scholarly leader. He was revealed to be manipulating all events in Soul Society from behind the scenes, having planned his betrayal for over a century. His Zanpakuto, Kyoka Suigetsu, creates complete hypnotic illusions, making anyone who has seen its release unable to distinguish reality from illusion. He is considered one of the greatest anime villains for his intelligence and the scale of his deception.

What Is Aizen's Plan?

Aizen sought to create the Oken (King's Key) to access the Soul King's palace and overthrow the Soul King, whom he considered an unworthy ruler of all existence. He needed 100,000 souls and a specific location (Karakura Town) to create the key. His plan involved defecting from Soul Society, building an army of Arrancar in Hueco Mundo, and orchestrating the Winter War. He had been manipulating events since before Ichigo was born.

What Is Kyoka Suigetsu?

Kyoka Suigetsu (Mirror Flower, Water Moon) is Aizen's Zanpakuto. Its Shikai ability, Kanzen Saimin (Complete Hypnosis), controls all five senses of anyone who has seen its release, creating illusions indistinguishable from reality. The only person immune was Ichigo Kurosaki, who had never seen its release. This ability made Aizen virtually unbeatable through conventional means.

How Is Aizen Defeated?

Aizen is not conventionally defeated. After fusing with the Hogyoku and achieving a transcendent form, he is weakened by Ichigo's Final Getsuga Tensho and then sealed by Urahara's kido. He is imprisoned in Muken (the lowest level of Soul Society's prison) for 20,000 years. He is never killed.
