Akatsuki

Akatsuki (暁, Akatsuki? lit. "Dawn" or "Daybreak") is a criminal organization composed of ten high-level ninja that have defected from their village of origin. The group receives little attention during the first part of the series, only becoming major antagonists in Part II. Akatsuki members are characterized by their long, dark cloaks bearing red clouds with a chin-high collar. Each also possesses a unique ring, which seems to symbolize one's membership in the organization. Members are partnered together in teams of two, each team sticking together as they traverse the Naruto world. Despite this partnership, members tend to have a strained relationship with their peers, only cooperating enough to complete their assignments and showing little concern when another member is killed. Orochimaru defects from the organization before the start of the series, taking his ring with him, and thus Akatsuki never exceeds nine members during the current storyline.

Akatsuki was founded by Madara Uchiha after he was expelled from his hometown of Konohagakure. Though initially meant only to mask Madara's movements, Akatsuki eventually began taking part in assassinations and espionage. By the start of the current storyline, Akatsuki's ambitions grow to plans of world domination. To mark this more dynamic goal, Akatsuki increases its activity throughout the series as it attempts to capture the nine powerful tailed beasts. Each member is assigned to capture a specific beast or its current host, at which point Akatsuki convenes to extract the beast and seal it away for their grand plan. As the Akatsuki leader, Pain, explains it, once all nine beasts have been captured Akatsuki will be able to harness their great strength to start world wars at their leisure. With the world governments unable to deal with the beasts' power, Akatsuki will be turned to for salvation, teaching the world the meaninglessness of fighting and giving Akatsuki complete control in the process. As of Naruto manga chapter 419, Akatsuki has captured seven of the tailed beasts.

Personality
Orochimaru's various human experiments take place so as to serve two purposes, most prominent of which is his desire to learn every jutsu in the Naruto world. Jiraiya speculates that this is due to the fact that his parents died when he was at a very young age, and flashbacks shown during his battle with the Third Hokage speak to this effect. Perhaps because he wanted to see his parents or as a means of avenging their deaths, he experiments on others to see what kind of modifications the human body can endure and to otherwise harness a subject's unique abilities for himself. Once accomplishing this goal, Orochimaru hopes to be worthy of the title of "ultimate being". Because a human's lifespan does not allow enough time to learn every jutsu, Orochimaru also experiments on others so as to achieve immortality. By living throughout the ages, Orochimaru need never worry about death and thus all the knowledge he gains will never be lost.

Above all else, Orochimaru cares only for himself. He grows bored when there is no conflict or violence in the world, and immediately strikes fear into others when they first meet him. Though he has a number of followers who would do anything for him, Orochimaru treats them as mere pawns. He does not hesitate to send them to their deaths for his own personal benefit, and only finds remorse in their loss if they are unable to properly complete a task. To win over these followers to their disposable status, Orochimaru approaches them with promises of making their dreams, such as obtaining power, revenge, or a purpose to their lives, come true. He applies a cursed seal to many of his stronger subordinates in order to corrode their body and mind, making them more susceptible to his influence and control.

Abilities
Much of Orochimaru's arsenal of abilities deals with snakes. By summoning them to his side during battle, Orochimaru can battle multiple opponents at once and simultaneously keep himself out of harm's way. Through his experimentations he has also been able to add some snake-like characteristics to his own body, such as shedding his body to escape injury or extending parts of his body to great lengths. Of the more common of his snake-related abilities, Orochimaru possesses the Kusanagi sword (草薙の剣, Kusanagi no Tsurugi?, English TV "The Grass Long Sword"), an extendable blade that he stores within a snake that is in turn stored in his own mouth. Though he can wield the sword regularly with great proficiency, it is not uncommon for him to use the sword without ever removing it from his mouth.

The influence snakes have had on Orochimaru is most evident in the results of his immortality research: after years of study and self-modifications, Orochimaru's "true" form has become that of a giant white snake that is composed of many smaller snakes. To live forever and escape death, Orochimaru first finds a new body that will act as his own. He then leaves the confines of the body he is inhabiting, revealing his true form. Once doing so, Orochimaru need only consume the new body and gain dominance over the soul of its current inhabitant, thus gaining complete control and access to all the body's unique abilities. While inhabiting this body, Orochimaru typically wears a mask of his original face, it being both his personal preference and easier for others to communicate with someone they recognize. Orochimaru can only perform this body-transfer once every three years, at which point in time weaker bodies begin to reject him and therefore necessitate he find a new body.
