Akatsuki

The is a criminal organization of S-Class missing-nins, minus Pain and Konan. Their main goal is to collect all of the tailed beasts for their plan of controlling the world. As such, the Akatsuki, despite initially having a minor role during the first half of the series, became the primary antagonists of the series, particularly in Naruto: Shippuden..

The Akatsuki; prior to the execution of their plans, at any given time had ten primary members, all of whom are or were S-Class from their respective villages. The Akatsuki always work in teams of two with the exception of Zetsu, who functions as the organization's spy, and make use of their unique skills to the teams advantage. Team members at the very least have to have functional team work with their partner even if they don't like each other. Despite this, it appears the organization hardly ever has a full meeting with them all together, as when they first met at the end of Part I, one said it was the first time in seven years they were all together.

The Akatsuki is widespread, spanning several countries with many agents possibly in all the ninja villages at least once. When one team finds a tailed beasts and has to begin the job of sealing the demon, they have hidden hideouts with many traps ready, to begin the sealing with the leader's astral projection for a three day long jutsu.

Goal
Main Goal: Although some members joined Akatsuki to further their own goals, all are united in Akatsuki's ultimate goal of gaining domination over the Shinobi world. The leader, Pain, has created a three-step process to work their way towards this goal. First, they plan to obtain a large amount of money to support their organization. Second, they plan to set up a mercenary group loyal only to Akatsuki. To build their reputation, they plan to accept any mission below the usual cost and operate off of the excess funds earned in the first part of their plan. Because there haven't been any wars in some time, the established shinobi villages can't afford to charge such low prices, leading the smaller countries to hire Akatsuki over the more expensive shinobi villages. By using the tailed beasts, Akatsuki can start wars and then immediately quell them, solidifying their reputation and convincing every country to depend on them, thus cornering the market in shinobi labor. Without any business, the other shinobi villages will collapse due to a lack of funds. Finally, after Akatsuki is the only major force of shinobi in existence, they can easily conquer the other countries. Members do not automatically learn of the plan upon joining; Hidan did not find out about it until he had been a member for quite some time.

The tailed beasts, nine gigantic demons of immense power, are the focus of much of Akatsuki's effort and screentime within the series. Each Akatsuki member is assigned to capture one of the nine beasts alive or, in most cases, the person that beast has been sealed into. Akatsuki has so far obtained seven of the nine: the first through the seventh tailed beasts.

However, this plan may just be a ruse as Akatsuki's three most prominent members have two separate goals in mind instead of controlling the world; one of which involves world peace.

Madara's Goal: Madara plans on using Akatsuki to gain the Tailed Beasts for himself and use their power to strengthen his Mangekyo Sharingan. Lately, he has shown great interest in destroying Konoha. He perhaps does want to conquer the world.

Pain's Goal: Pain later went into further detail on the tailed beasts' role in his plans. The beasts would be used to create a deadly kinjutsu technique that could wipe out one of the five great nations in an instant, so if countries go to war and do not have ninja villages to fight for them they would turn to the Akatsuki and their technique. Whichever side uses the technique first would wipe out the opposing country, which would scare them into never using their weapon again, and scare the other countries to never start a war or they would be wiped out too. Through the mutual fear, war would cease to exist, and the world would know everlasting peace.

This greatly conflicts with Madara's plan so this goal could in fact be a secret goal that only Pain and Konan are aware of.

Wardrobe
Akatsuki members have a similar way of dress, which could give them away if a village is alerted of their presence. Members wear long dark cloak with red clouds, red interior with a chin-high collar. All members wear nail polish of varying colors on their finger and toenails, and may wear a conical straw hat with small spike-like balls hanging down to cover their faces. The hats may be used to move around in the general population unnoticed, or for when the weather requires one. Some members tend to wear their village headband with a scar through the middle to show their defection.

Colors of fingers and toenails are:
 * Pain/Konan; black
 * Itachi Uchiha/Kisame Hoshigaki; shade of purple
 * Deidara; black
 * Sasori; teal
 * Kakuzu/Hidan; dark green
 * Zetsu; light purple

What seems to be most important however are their rings. In total there are ten rings given to each of the ten main members of the Akatsuki. It appears these rings are important to being a member of the Akatsuki as when Orochimaru defects, he takes his ring with him and as such wasn't replaced. The rings may be connected to the sealing jutsu used to extract the tailed beasts but it has not been confirmed.

The various rings are:
 * Right thumb: ; currently worn by Pain,
 * Right index finger: ; formerly worn by Deidara,
 * Right middle finger: ; currently worn by Konan,
 * Right ring finger: ; formerly worn by Itachi Uchiha,
 * Right little finger: ; currently worn by Zetsu,
 * Left little finger: ; formerly worn by Orochimaru,
 * Left ring finger: ; currently worn by Kisame Hoshigaki,
 * Left middle finger: ; formerly worn by Kakuzu,
 * Left index finger: ; formerly worn by Hidan,
 * Left thumb: ; currently worn by Tobi (Madara Uchiha), formerly worn by Sasori.

Eight of the ten kanji of the rings are taken from a kuji-in (Nine Syllable Seals): a collection of nine hand postures used in meditation. These kuji-in have found their way into ninja folklore as a kind of magic spells. Pain's "rei" and Zetsu's "gai" are not from this kuji-in. However, the only unused kuji-in kanji,, bears a strong resemblance to Zetsu's "gai," suggesting an error. It would be a consistent error, however, since the "gai" kanji has been used in every instance the ring's kanji has been shown, both in the manga and the data books.

Recently, Team Hawk has allied themselves with Akatsuki. They also wear the Akatsuki cloaks, but they seem to have their high collars folded down. None of them wears a headband, nail polishes, conical straw hats, nor the rings; of the latter only the Suzaku, Kūchin, and Hokuto are known to be recoverable, whilst the santai worn by Hidan and the Seiryū worn by Deidara were most likely destroyed in the explosions that defeated them.

Teams
The Akatsuki Teams are put together in teams of two to exploit combined strengths for the Organization's goals to be met. Each team is lead by a senior member of the Organization. Each member of a team seem to have similarities with each other.

Active
Pain/Konan A team that so far, functions very well with each other, evident that Konan is the only member to refer to Pain by name. As the leader of Akatsuki, Pain directs the rest of the organization to their respective goals, his most direct interaction with the organization is using the Illusionary Dragon Nine Consuming Seals. Pain is the leader of Amegakure, and has sense been referred to as a god there. Konan for doing her duties to Pain has been declared God's Angel.
 * Senior: Pain
 * Similarity: This team has three similarities.
 * Divinity titles (God for Pain; Angel for Konan)
 * Childhood Friends
 * Not trusted by Madara
 * Target: Nine-Tailed Demon Fox

Team Hawk Due to the loss of five members, Akatsuki lost strength that it used to have, so Madara Uchiha enlisted the aid of Team Hawk, whose mission was also the destruction of Konoha. To complete their goals, Madara ordered Hawk to hunt the Eight-Tailed beast while Akatsuki hunts the demon fox. Technically, the members of Hawk are not full members of the Akatsuki, as they do not possess the rings worn by each of the full members.
 * Senior: Sasuke
 * Similarity: This team has two similarities.
 * Former association with Orochimaru.
 * Cursed Seals (Sasuke and Juugo only)
 * Targets: Eight-Tails

Zetsu Not technically a team, but Zetsu has two personalities, effectively making it a team of two. Since each side has a level of individuality, they frequently argue with each other over which battles to watch, among other things.
 * Status: Active
 * Similarity: Same Person
 * Target: Unknown

Inactive
Orochimaru/Sasori Sasori claimed that he and Orochimaru worked well together during their partnership. However, when Orochimaru defected from Akatsuki after his failed attempt on stealing Itachi's body, Sasori has developed a grudge against his partner.
 * Senior: Presumably Orochimaru.
 * Similarity: This team has four similarities.
 * Body modification for eternal youth (Living Corpse Reincarnation for Orochimaru; Human Puppets for Sasori)
 * Orphaned at young age.
 * Poisonous animal themed names (Snake for Orochimaru; Scorpion for Sasori).
 * Nicknamed ("Orochimaru the Giant Snake"; "Sasori of the Red Sand").
 * Target: Unknown.

Itachi/Kisame A team that functioned well together and was unbelievably effective. Mission wise; the team completed almost every assignment Pain gave them with little trouble with the Nine-Tailed Fox being the only known exception. Unlike most Akatsuki teams, Kisame and Itachi got along fairly well; Kisame did as Itachi asked unquestioningly and they would often converse casually when not in combat.
 * Senior: Itachi.
 * Similarity: This team has three similarities.
 * Elemental users (Fire for Itachi; Water for Kisame).
 * Animal themed names (Weasel for Itachi; Shark for Kisame).
 * A last name (unlike the other members) (Uchiha Itachi; Hoshigaki Kisame).
 * Targets: Nine-Tailed Demon Fox (Failed), Four-Tailed beast (Sealed).

Sasori/Deidara Formed by the two artists of Akatsuki, Sasori and Deidara worked well for the most part but had conflicting ideas on art. Sasori thought all art was to be permanent, such as his puppets, while Deidara thought art was instantaneous and then gone forever, such as his exploding clay. Sasori, having many connections, was able to get a spy into Sunagakure for years before their arrival, to learn the villages defenses for their raid. The team also had several arguments and debates on plans, Sasori being a impatient man and wanting to finish missions quickly as possible though this is compensated by Deidara's way of executing such plans; the battle against Gaara being an example.
 * Senior: Sasori.
 * Similarity:
 * Artistic values (Human Puppets for Sasori; Exploding Clay for Deidara).
 * Both comitted a type of suicide (Sasori allowing himself to be killed; Deidara choosing to self-destruct himself).
 * Target: One-Tailed Shukaku (Sealed), Nine-Tailed Demon Fox (Failed).

Kakuzu/Hidan A very effective yet unruly team; usually doing unrelated jobs and always late. Pain decided to put these two together because of their unique abilities. Hidan, as a result of a "Jashin experiment" could not be killed, even by decapitation, and Kakuzu could easily go into a rage and kill anyone around him, including his partner. Therefore, with Hidan, Kakuzu can go into a rage and not worry about his partners' life afterwards. They have shown the most hostility towards each other due to a conflict of interest; Kakuzu sees the rituals and beliefs of Hidan's religion to be a waste of time, and Hidan sees Kakuzu's willingness to do blasphemous things and his greediness to be unbearable, not to mention that Kakuzu's job as a bounty hunter usually gets on Hidan's nerve. Their team was assigned to capture the Two-Tailed Demon Cat, but later decided to also capture unknown target, because they happened to be close to the Land of Fire after capturing Yugito Nii; after the sealing of the Two and Three Tails, they decided to go after Nine-Tailed Demon Fox.
 * Senior: Kakuzu.
 * Similarity: This team has five similarities.
 * Invulnerability (Multiple hearts for Kakuzu; Jashin immortality for Hidan).
 * Murderously violence associated with ways of severing ties with their villages.
 * Dislike for each other's ideals.
 * Murders to maintain invulnerbility (Stealing hearts for Kakuzu; Maintaining religion power for Hidan).
 * First kanji of name related with Shogi ("Kakugyo" for Kakuzu; "Hisha" for Hidan).
 * Targets: Two-Tailed Demon Cat (Sealed), Nine-Tailed Demon Fox (Failed), Unknown Target (Failed).

Deidara/Tobi Formed after the death of Sasori, Tobi was introduced as his easily found replacement. Despite Tobi's eagerness to please his "senpai", his childish attitude was seen as a annoyance to Deidara's expectations of the organization. Beyond this, the two worked well together, with Tobi planting much of Deidara's explosive clay underground during their fights. When Deidara was about to blow himself up to kill Sasuke Uchiha, he apologized to Tobi, saying that he too would be caught up in the blast.
 * Senior: Deidara.
 * Similarity: Both annoying to senior (Deidara to Sasori, Tobi to Deidara).
 * Target: Three-tailed beast (Sealed).

Creation and Conception
In the Naruto Hiden: Sha no Sho Character Official Data Book, Masashi Kishimoto stated that he had originaly planned on making the Akatsuki a group of monsters with almost no human characteristics. He also states that the Akatsuki teams get two single rooms to sleep in.
