Yoruichi Shihōin

is the former Captain of the 2nd Division of the Gotei 13 as well as the former Commander of the Special Forces. Yoruichi, along with Kisuke Urahara helps Ichigo Kurosaki, throughout training to become stronger so that he could face face Byakuya.

Appearance and Personality
Yoruichi Shihōin is a highly attractive, dark-skinned woman with golden-colored eyes and purple hair, who can transform into a black cat for long periods of time.

She is intelligent and witty, and is intimately knowledgeable of Soul Society and its workings, as she was the former leader of the special forces and the Second Division's captain. Although of noble birth, she acts differently from other nobles. For instance, she instructed Soifon to refer to her without using honorific suffixes, but reluctantly settled for being called "Yoruichi-sama" ("Lady Yoruichi" in the dub). She also transforms into her human form directly in front of Ichigo on several occasions just to see his reaction to seeing her naked, which she even teases him about. Another note of her eccentricity is that she speaks in a dialect that elders use, such as identifying herself as "washi" (a term that usually old men define themselves with) instead of more feminine terms like "watashi" in both her human and animal forms (though specifically for the Japanese version).

Yoruichi tends to avoid battles, preferring to help after a fight is over, but she will step in if she thinks her side cannot win. She was responsible for training Chad and Orihime prior to their entrance into Soul Society. She also supervised Ichigo Kurosaki's Bankai training using the methods developed by Kisuke Urahara. According to Tite Kubo, the author of Bleach, Yoruichi prefers to drink milk, which fits with her practice of transforming into a cat much of the time.

History
Yoruichi was the once the 2nd Division Captain of the Gotei 13, Commander of the Secret Mobile Corps, and Corps Commander of the Corrections Corps. She was also the 22nd generational head of the, one of the four noble families, and the first female as such. She earned much respect in Soul Society in all of her positions. While her age has not been revealed, she is considerably older than Byakuya Kuchiki and refers to him as "Little Byakuya" since he was a kid. This was confirmed in Turn back the pendulum, where Byakuya was still a kid and she was already a captain and was probably on good terms with his grandfather.

While Yoruichi was the special forces commander, she took in Soifon as a guard and became her mentor and friend. She taught Soifon most of the techniques she knew. As a result, Soifon succeeded her as head of the special forces after Yoruichi's escape from Soul Society. During her time in Soul Society, she created many techniques that involve Flash Steps, as well as teaching some of them to Byakuya. About 100 years prior to the Bleach storyline, she helped Kisuke Urahara in his escape from Soul Society and was thus relieved of her high status. Yoruichi and Urahara are close friends, as they played together daily under the Sōkyoku hill training space, which Urahara built when they were children.

Since her departure from Soul Society, it has been stated that she "has kept her distance from battle", meaning that since she disappeared, she has not fought in battle for over 100 years before the storyline. Her segregation from fighting seems to be the main reason for Yoruichi's initial struggle during her fight with Soifon after she returns to Soul Society.

Synopsis
Yoruichi first appears in feline form, and helps train Orihime Inoue and Yasutora Sado to control their newly acquired powers. She leads Ichigo's group into Soul Society when they attempt to save Rukia Kuchiki, and then to Kūkaku Shiba when they are unable to enter through the Seireitei gates. After being separated from the group, Yoruichi collects information on Rukia's execution. She also rescues Ichigo from being injured by Byakuya's Shikai and claims that he cannot fight as he is; she works to teach Ichigo the Bankai of his Zanpakutō using a technique developed by Urahara. Later, Yoruichi battles with Soifon, albeit with some struggle in the beginning. When Yoruichi reveals that she also is able to use shunko, Soifon is overcome with rage, and soon defeated. Yoruichi returns to the human world with Ichigo and his friends.

Yoruichi, alongside Soifon, later actively begin to pursue the Bount once they learn of the Bount's plan to invade Soul Society, and also saves Ichigo when he is unable to defeat Jin Kariya. Yoruichi also rescued the Bount Koga Gō and took him to the home of Ran'tao, the Bount's creator, where he was nursed back to health.

Subsequently, Yoruichi and Urahara rescue Ichigo from death at the hands of the Espada, Yammy. Though she appears to easily defeat Yammy, it becomes apparent from her injuries afterward that her opponent was stronger than she expected due to his tough skin. She appears again to take Orihime to the training room under Urahara's shop to prevent Aizen from gaining interest in her abilities.

Equipment
Two of Yoruichi's unique items are accessories which grant the user the power of flight.


 * One is a small wand with a skull atop it. By channeling spirit energy into the wand, it produces a tentacle that acts as a harness and a single, bat-shaped wing that acts as a one-handed hang glider. No skill or previous experience is required to use it.


 * it is a brown mantle with a large draw string closure at the collar and a large brooch displaying the Shihōin family crest. Like the wand, the tentōken seems to require no skill or previous experience to use. It also seems to be superior to the wand, since it allows one to hover in mid-air and doesn't immobilize one of the user's hands.

Another item, though not in Yoruichi's possession, though apparently belonging to her family.


 * Shihōin Shield: the device used by Jūshirō Ukitake and Shunsui Kyōraku to destroy the Sōkyoku. It is a large, shield-like item with the Shihōin family crest stamped on it and a long cord connected to it. When the cord is wrapped around Sōkyoku and two Zanpakutō are stabbed into two vertical slots running from its top, their energy flows through the cord and destroys Sōkyoku. Jūshirō Ukitake had it in his possession under some sort of seal.

Powers & Abilities
As a member of a noble family and head of the special forces, Yoruichi has acquired many powerful abilities and artifacts.

Feline Transformation: One of her most important and unique abilities is that she can shapeshift into a black cat at will. It is unknown if this ability possesses any time limit, but it is unlikely considering she has used it for so long that she is unused to her human form and dislikes wearing clothing (much to Ichigo's chagrin). As a cat, Yoruichi can still channel spiritual power and move with incredible speeds, though she is physically limited by the form. Her transformation also allows her a complete disguise in multiple ways; aside from the physical transformation, her voice as a cat is deep enough for most to assume that she is male.

Flash Step Master: Yoruichi is also highly skilled in the use of Flash Steps, a high speed movement ability. Though this is by no means a unique skill, as most seated officers are capable of performing it to various degrees, Yoruichi holds the title because she has mastered this ability to such an extent that she can appear to be in several places at once and wipe out entire special forces squadrons in moments. The full extent of her abilities remain unclear, but she was able to outrun Byakuya while carrying an unconscious Ichigo over her shoulder. She was able to perform around 300 steps before feeling out of breath. Furthermore, she states that she is out of practice after doing so. She is so fast that Soifon could barely keep up with her and she was able to take out a multitude of Special Forces operatives in a matter of seconds.


 * Yoruichi is also skilled with Flash Cry, a technique that combines hand-to-hand combat and Kidō. It concentrates high-pressure Spiritual Energy around the body, allowing it to be fired at opponents. It can also be used to instantly neutralize an opponent's movement.

Master Hand-to-Hand Combatant: Yoruichi is often seen fighting hand-to-hand, and has never even used her Zanpakutō, making one wonder if she even possesses one. Her mastery in this area is so great that she may be the most proficient in it of all Shinigami alive. Taking on the likes of high level Arrancar with no problem, she is even being considered to be highly dangerous by the 4th Espada, Ulquiorra Schiffer.

Zanpakutō
It is known that Yoruichi possesses a Zanpakutō, but she relies nearly exclusively on hand to hand combat, Flash Cry and Flash Steps. However, although she never carries it during the main storyline, it is shown during a flashback when she tells Ichigo about Kisuke Urahara as the previous captain of the 12th division. She briefly uses a sword during the "Sealed Sword Frenzy" OVA to dispatch a Hollow. She also uses it in the anime during Soifon's flashback about becoming Yoruichi's protégé, where it resembles a kodachi or wakizashi.
