Two-Tails: Matatabi

This is, arguably, the most powerful ability of a Jinchuuriki. The Jinchuuriki is able to use the Bijuu's power to recreate it as a perfect replica, potentially, with full access to the Bijuu's original power. This is incredibly difficult to master and takes great time and practice. Once, in any of the following transformations, the Jinchuuriki can gain access to the fully powered Tailed Beast Ball.

Initial Transformation EXP Cost: 0 EXP Requirements: Mastered Initial Jinchuuriki Mode, Mastered Version One Jinchuuriki Mode, Mastered Version Two Jinchuuriki Mode The Transformation is similar to a Combination Transformation technique performed with a giant summon. The Bijuu is created in perfect form, but it's power is not yet fully accessible. For each post this is used, 15 CP is deducted from the Bijuu's chakra. If the Jinchuuriki attempts to use this without mastering the required forms, the transformation will fail and the Jinchuuriki will become a comical miniature version of the Bijuu that has the same stats as the Jinchuuriki at base. Effect: -3 Tiers to all Bijuu's Stats

Partial Transformation EXP Cost: 250 EXP Requirements: Same as Initial Now a considerable amount of the Bijuu is beginning to project into the Transformation as the Jinchuuriki becomes more accustomed to properly siphoning that power. Initial Transformation will cost 15% of the Bijuu's chakra per post. Using Partial Transformation costs 15 CP per post and the Jinchuuriki must have activated the Initial at least 10 different times over 10 topics. Effect:  -2 Tiers to all Bijuu's Stats

Advanced Transformation EXP Cost: 250 EXP Requirements: Partial Transformation obtained and Control The Jinchuuriki is now near the full might of their Bijuu. Advanced Transformation costs 20 CP per post. Effect: -1 Tier to all Bijuu's Stats

Complete Transformation EXP Cost: 250 EXP Requirements: Advanced Transformation After having used Advanced 20 times over 20 different topics, the Jinchuuriki may now use the full might of the Bijuu. Complete Transformation costs 25 CP per post. Effect: User now uses all of the Bijuu's Stats

Master Transformation EXP Cost: 250 EXP Requirements: Complete Transformation and Bond Does not provide any increases to the power of the Tailed Beast Mode, but it does allow for Partial Transformations that vary in size from the Jinchuuriki's body to the Bijuu's Body. Any portion can be transformed, at will, and should the Jinchuuriki have mastered Chakra Mode, the altered part can also be comprised solely of the Bijuu's Chakra. Mastered Transformation costs 30 CP per post.

Chakra Mode is the state a Jinchuuriki enters when they decide to use the Bijuu's chakra, in full, and apply it to their bodies. This can happen when the Jinchuuriki has acquired Control over the Tailed Beasts's Chakra and can quickly burn up the seal, making it very difficult to use with weaker seals. This cloak takes on a flaming appearance with color varying by Jinchuuriki and Bijuu, as just like one's chakra is colored by one's unique Yin-Yang energy balance -- so too -- is the Chakra mode colored by the unique balance between Bijuu and Host. There are different levels for this mode based on general Bijuu mastery and use of this ability.
Effect: Chakra Mode provides an S++ Rank Defense

Cloak EXP Cost: 0 EXP Requirement: Control The Jinchuuriki's Chakra mode appears as a simple shroud of flame-like chakra coating the body and clothing. This takes on the shape of the host with the sole addition of sealing patterns based on the specific Fuuinjutsu used to contain the Bijuu. This level can use all Tailed Beast abilities, save only for the full-sized Tailed Beast Ball, though it can still make use of the smaller A-Rank variant. Effect:  +2 Unique Tier Boost to Strength, Constitution, Speed, and Coordination Chakra Cost: 30 CP per post from the Jinchuuriki

Shroud EXP Cost: 0 EXP Requirement: Bond The coating of Chakra Mode enhances to form it's own cloak-like appearance, covering the Jinchuuriki in an extra set of clothing made entirely from the energy of the Bijuu. The seal markings present in the Shroud-Level enchances and spread further and the eyes change to resemble that of the Bijuu's. Effect:  Same effect as Shroud -- except the Tailed Beast no longer siphon's the host's Chakra Chakra Cost: 30 CP per post from the Bijuu's Chakra

Unity EXP Cost: 500 EXP Requirement: Shroud and Cloak unlocked The Jinchuuriki and Bijuu become accustomed to unifying their energies and are able to synchronize on a far higher level than before. Rather than shelving their own chakra, Jinchuuriki are able to combine and enhance it with their Bijuu's chakra, using the impressive potency of the demonic chakra to bolster their own reserves. Effect:  No longer does the Bijuu's Stamina stat replace the Jinchuuriki's. The Jinchuuriki's CP and the Bijuu's CP are now added tegether for this purpose. Chakra Cost: 30 CP per post from the combined Chakra

Mastery EXP Cost: 500 EXP Requirement: Unity Unlocked So much expedrience has the Jinchuuriki gained in using the Bijuu's chakra that they can manipulate each other's energies as their own. The Jinchuuriki can now use chakra to enter into the Tailed Beast Mode, standing amidst the head or within the arms, hands, feet, or tails behind a veil of translucent (but very solid) Bijuu energy. It will appear just as the Bijuu does, but with the same color and seal pattern as are present in the Chakra Mode and, should the Jinchuuriki have reached the Master Level of Tailed Beast Mode, they can partially form parts of the Bijuu out of chakra -- without the need to actually change their own bodies. The Jinchuuriki has the ability to project Tailed Beast Mode beyond their body. It drains chakra at it's own cost, in conjuction with whatever the Jinchuuriki uses, but the Bijuu can fight as a summon would -- separate from it's host and with it's full power. The actual power of this level is determined by the level of Tailed Beast Mode that the Jinchuuriki has acquired. Chakra Cost: 30 CP per post

Killing a Bijuu
It is not normally possible to kill a Bijuu when it is outside of it's host. This means that the death of the host is the most common way to end a Bijuu's life. When the host dies, by any means other than the seal breaking, the Bijuu will also die. When the Bijuu dies, it's body decays over several days until nothing is left and the chakra composing it's form scatters around the continent. This chakra will eventually reform, giving new life to the Bijuu -- but the time it takes can vary greatly by the method of it's death, the environment in which it died, and overall power of the Bijuu -- Denoted by it's number of tails. Most takes months, but some can take years.

Bijuu and Genjutsu
A Bijuu can be affected by a Genjutsu, however, due to their naturally high INT and PER, it may be very difficult to catch them in one -- even when not sealed in a host. When they are sealed, however, Bijuu can only be affected by Genjutsu cast through the eyes, typically via a Doujutsu (most often through the Sharingan). The effects of the Genjutsu on a Bijuu are generally specified by the Illusion, but are typically minor because the Bijuu are naturally strong-willed.

It is through special Genjutsu that Bijuu are manipulated, and again, usually by the Sharingan. However, their strong-will will resist this control and, while they may not be capable of breaking the control immediately on their own, they can fail to perform certain orders issued to them -- if those orders go against their nature. ((A Bijuu that is normally destructive and hateful of humanity will not follow an order to help people rebuild)). No Bijuu will obey an order that will lead to their sealing or death. Forcing them to fight, destroy, and kill is typically very easy.

When a Genjutsu affects the host of a Bijuu, that Bijuu does have the ability to cast Genjutsu: Kai on the Jinchuuriki to dispel it. However, most Bijuu don't care enough to do this and, unless the Genjutsu is a direct threat to the life of the Bijuu, it will generally neglect to lend any aid. When a Bond is formed, however, the Bijuu may actively work to keep the Jinchuuriki free of any illusions -- such that, in order to affect a Jinchuuriki with a Genjutsu, one will likely have to affect the Bijuu with one as well. A Bijuu casting Genjutsu: Kai does not heal nor cancel any psychological damage that is incurred as the result of the host falling under the use of Genjutsu.

Boost and Stacking
The stats granted by any of the abilities on this page are considered "Unique Boosters" and do not count towards the 2-Tier limit to boosting. This also means that a Jinchuuriki can potentially stack with a Tailed Beast ability to reach even higher stats. This is rare, however, as Bijuu Chakra is generally incompatible with other techniques, especially those that involve "flow" do to it's erratic nature, which may instantly dispel any sort of Chakra Flow jutsu.
:: While using the Unique Ability, Chakra Access, or Healing -- the Jinchuuriki can activate any booster desired.
:: When using Initial Jinchuuriki Mode, Version One, or Version Two: No boosters can be stacked. Any of these that are mastered, however, will allow for boosts pertaining to Taijutsu ONLY, and so long as the Jinchuuriki's Intelligence remains above E-Tier.
:: When Control is gained, the Jinchuuriki may use any boosters desired with the Initial Jinchuuriki Mode and can use any physical boosts, such as Taijutsu, Bukijutsu, and Kenjutsu with the Version One and Version Two forms.
:: Tailed Beast Mode does not allow any boosters that are not specifically designed to be used while in Tailed Beast Mode.
:: Chakra Mode can be much more lenient.

Before a Bond is formed, the Bijuu's chakra does not mesh well with most boosters, but similar to the Controlled Version Forms, Chakra Mode will allow for Physical Boosters. It isn't until a Bond is formed that the Bijuu's chakra becomes compatible with the host's and allows for any other type of boosters to be used with it.
