Basic Jinchuuriki/Bijuu Info
Tailed Beast: Shukaku the Ichibi (One-Tailed Demon Tanuki)
Village of Origin: Sunagakure (Hidden Sand Village)
Current Host and Village:
Method of Sealing:

Spoiler:

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain an ability to move and levitate sand at will, and is protected at all times by the Shield of Sand, regardless of his will (even self-inflicted injuries are prevented by the sand). He also suffers from lifelong insomnia, a side effect of being Shukaku's host. Should he fall asleep, Shukaku would eat away at his personality.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• Half Tail: The Jinchuuriki transforms into a human-sized version of the Shukaku by layering sand over it’s body. The sand takes on the appearance of the Shukaku, and enhances his abilities greatly. The weak point of this transformation is at the base of its tail, where any strong enough blow (such as an exploding note) will cause severe damage to it. He can also stretch his sand limbs as he does with his regular sand, the primary difference being that his limbs remain just as strong as when they are retracted. This transformation seems to occur very slowly.
  
• One Tail: In desperate situations, the Jinchuuriki would instantly create a giant copy of Shukaku with himself hidden inside. While he is awake, the Jinchuuriki still has control of Shukaku's body and can fight "normally" with it. While in this form, Jinchuuriki transfers his eyesight to that of Shukaku's body in turn resulting in his own eyes losing their pupils. Unlike his smaller Shukaku form, this seems to be less able reform itself if damage, if it can at all. When the Jinchuuriki needs Shukaku's full power, he would expose his upper body on top of Shukaku's head and use the Feigning Sleep Technique, which allows Shukaku to take full control over its body. While taking over the body, Shukaku's eyes will become more apparent, changing from a simple light brown pupil, to its original version of a yellow pupil with a small black star with four blue dots around it. Shukaku can use Wind Release: Drilling Air Bullet, by pressing compressed air out of it's stomach, to cause major blunt damage to its opponents. The major weak spot of the Full Shukaku Form is as expected by the Jinchuuriki himself being Shukaku's chakra that keeps the large creation going.
  

Unique Jutsus:
Name: Suna no Tate - Genjutsu Toxin
Effect: Whenever the Jinchuuriki is about to come to harm, a shield of sand will automatically surround and protect him. The sand will react regardless of the user’s will, even protecting him from self-inflicted injuries. The shield is capable of withstanding considerably strong attacks and projectiles, and can be hardened to a point where it's stronger than steel. It can be defeated by avoiding it completely with extremely high-speed attacks, or merely overcoming the shield with incredible brute force.

Name: Sunata – Sand Manipulation
Effect: The Jinchuurki possessed the ability to manipulate sand, typically moving it through the air to serve various purposes. The amount of sand he can control at one time is fairly immense, as in Part II he is able to gather enough sand to cover Sunagakure as a shield. If sand is lacking in abundance, the Jinchuuriki can break down the earth minerals in the ground to create more sand.

Name: Renkūdan - Drilling Air Bullet
Effect: Taking in a deep breath and distending his stomach, the user will punch himself in the gut, shooting large balls of compressed air and chakra at an opponent, causing an enormous conflagration if it hits. As expected from a tailed beast, this attack is very dangerous as even the large Gamabunta was in danger from the attack. The extra wind created when the attack is released is enough to raze a forest.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Nibi (Two-Tailed Demon Cat)
Village of Origin: Kumoakure (Hidden Cloud Village)
Current Host and Village:
Method of Sealing: Akatsuki Collar

Spoiler:

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain a massive increase in fire affinity, making all their fire jutsu hot enough to produce blue flames.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• One Tail: The Jinchuuriki gains a visible aura of the Bijuu’s chakra, including the shape of a tail. The agility and speed greatly increases along with his eye sight. The chakra surrounding the Jinchuuriki is actually a blue fire that protectes their body from taijutsu.
  
• Two Tails: The Jinchuuriki's form is transformed completely into that of the Bijuu. The Jinchuuriki now has the ability to fire large fire balls from it’s mouth with relative ease. The Jinchuuriki has access to Nibi's Menacing Ball.

Unique Jutsus:
Name: Ayatori – Cat’s Cradle
Effect: With all cats believed to having nine lives, the Nibi is no exception. While Nibi is able to heal/survive a total of nine fatal attacks, it sacrifices one ninth of it’s chakra limit; meaning that each time it survives, the Nibi gives up a ninth of it’s max chakra that can never be returned.

Name: Okibi – Blazing Fire
Effect: This inherent ability allows Nibi's host to influence fire in an intense heat. With the unbearable heat, all of the user’s fire turns to an illuminating blue increasing its power. Even water and other fire jutsu cannot suppress the intense heat.

Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Nibi’s case, they are blue-colored fire blasts.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Sanbi (Three-Tailed Demon Turtle)
Village of Origin:
Current Host and Village: Yaguri (Kirigakure No Sato)
Method of Sealing: Birth
Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain two of the Sanbi's Signature Abilities; Toxic Mist and the ability to manipulate water at will, known as Tidal Influence.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.
One Tail: The Jinchuuriki gains a visible aura of the Sanbi's chakra, including the shape of a tail. The skin becomes tougher, increasing physical defense. The Jinchuuriki now has the ability to manipulate tidal influences at will on a small scale with little chakra use.
Two Tails: The Jinchuuriki begins to take on physical characteristics akin to Sanbi. The aura becomes more concentrated, and a second "tail" appears. The Sanbi's signature hallucinogen is able to be produced in the body and passed into water for effects. Medium-scale tidal manipulation is allowed.
Three Tails (Full Release): The Jinchuuriki's form is transformed completely into that of the Sanbi. The voice becomes much more intense, with a roar powerful enough to produce a shockwave. The hallucinogen is able to be released as an airborne mist. Large-scale water manipulation is allowed. The Jinchuuriki has access to Sanbi's Menacing Ball.


Unique Jutsus:
Name: Kiridoku - Toxic Mist
Effect: Once the Jinchuuriki's body starts to take on the Sanbi's charateristics, it will begin to synthesize this toxin. It can be used as any other poison, inflicting a hallucinogenic effect on the victim that exploits their greatest fears. In lower levels it is restricted to liquid form; at higher levels it can be released as a vapor.

Name: Shiononagare - Tidal Influence
Effect: This inherent ability allows Sanbi's host to manipulate water and moisture, typically moving it through the air to serve various purposes such as blocking attacks, binding or drowning opponents, and shaping the water into various attacks. If water is lacking in abundance, the Jinchuuriki can use the moisture in the air or utilize groundwater.

Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Sanbi's case, they are white-colored shockwave blasts.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Yonbi (Four-Tailed Demon Ape)
Village of Origin: Iwagakure (Hidden Rock)
Current Host and Village: Daisuke Hikaru (Kirigakure/Kusagakure)

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain an ability to manipulate lava through the use of fire and earth elements.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• One Tail: The Jinchuuriki gains a visible aura of the Yonbi's chakra, including the shape of a tail. The skin becomes tougher, increasing physical defense. Able to bend metal and other weaker materials.
  
• Two Tails: The Jinchuuriki begins to take on physical characteristics akin to Yonbi. The aura becomes more concentrated, and a second "tail" appears. During this, the muscles grow significantly and the Jinchuuriki can block from C rank an lower physical jutsu with own hands.
  
• Three Tails: The chakra surrounding the Jinchuurki becomes almost solid and a third tail sprouts from it. Now able to block against B rank jutsu barely.
  
• Four Tails (Full Release): The Jinchuuriki's form is transformed completely into that of the Yonbi. As one of the strongest of the bijuu in physical strength, he is now able to cause small earthquakes by smashing his fists to the ground. With this, he is able to destroy almost all regular earth jutsu. The Jinchuuriki has access to Yonbi's Menacing Ball.
  

Unique Jutsus:
Name: Kazanbai – Volcanic Ash
Effect: With the lava stirring in their gut, the Jinchuuriki or Bijuu is able to exhale a large amount of smoke and ash that can be used as a smoke screen. While the fumes make it hard for others to breath, the Jinchuuriki is unaffected.

Name: Kakkazan – Active Volcano
Effect: This inherent ability allows Yonbi's host to combine fire and earth-based chakra to create a torrent of lava that can melt away anything by expelling it through the mouth. At higher levels, it can also be hardened into igneous rock.

Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Yonbi's case, they are orange-colored magma/plasma blasts.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Gobi
Village of Origin: Yukigakure
Current Host and Village: -
Method of Sealing: -

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain a sub specialty to there dominant of Genjutsu. However, due to the nature of the tails corresponding with the elements, the Jinchuuriki loses the ability to use elemental based jutsus due to conflicting elements because of the Gobi. However their chakra control increases greatly.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• One Tail: By releasing this tail a haze begins to cover the Jinchuuriki’s body. The haze itself is the color of the 5 elements; blue for water, red for fire, yellow for lightning, green for wind, brown for earth. When this tail is activated the user is allowed to utilize any Genjutsu they know for a chakra cost one rank lower than the jutsu itself (Ie. B-Rank costs C-Rank).
  
• Two Tails: A second tail appears behind the user as the colors become more vivid and solid, instead of a haze, its more like a thick fog. The use’s body becomes harder to see due to the fog. When this tail is activated, the users Genjutsu become increasing hard to break out of, requiring an extra burst of chakra equal to 1 rank lower than the Genjutsu’s rank. (Ie. Breaking out of a B-Rank Genjutsu costs a B-Ranked amount of chakra, and then a C-Rank amount of chakra as well).
  
• Three Tails: By activating the third tail, the user’s body becomes fully enveloped in the rainbow light and cannot be seen anymore. The rainbow chakra that surrounds the users body forms a shimmering bone structure that resembles a wolf or a canine. Also, the user’s Genjutsu take on an area of effect characteristic. By excreting the chakra in a 10 meter radius, the user is able to cause any Genjutsu they use to affect everyone in that area.
  
• Four Tails: When this tail is activated, the user’s body is covered in a muscular and organ system, held in place by a rainbow chakra form. By accessing this tail, the user gains complete immunity to all Genjutsu, clan based or not. (Ie. Genjutsu used on 4 tails, Genjutsu bounces right off. No Kai needed).
  
• Five Tails (Full Release): At this stage, the Gobi is fully formed, however the user is still alive. Depending on if the user has managed to control the Gobi depends on who controls this form.
  
  Visibly, the figure is a white wolf with 5 tails, a rainbow haze around it. By accessing this form, the user (should they be in control) is allowed to make illusions on the spot, instead of needing to use a premade jutsu.
  

Unique Jutsus:

Name: Imari - Menacing Ball

Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Gobi’s case, they are rainbow-colored chakra blast. This is available from the first tail.

Name: Birth

Effects: Birth is a unique Genjutsu. When it is used, the user will fall back into an area where they cannot be seen by the opponent. The farther they move back, the more likely the opponent will fall into the trap, however the user cannot move back too far, otherwise the opponent will suspect something.

After about 50-100 meters, depending on the terrain around the user (more cover requires less length), the opponent will find themselves in a giant crater, which smells like sulfur. The entire area seems to have been reverted back to a pre-human age, as the air seems to become harder to breath due to the seeming lack of oxygen in the air. A yellow fog will be filling the air and the entire area will be devoid of life. Geysers and hot bubbling water that sizzles when it hits the air will be present everywhere.

When the opponent turns around, they will see a hill, signifying the wall of the crater. The opponent has approximately 3 posts to realize they are in a Genjutsu and escape before they will start to experience asphyxiation and suffocate. They won’t actually die outside the illusion, but will fall unconscious from the mental trauma. The suffocation lasts another 3 posts.

Name: Destruction Blast

Effect:The user starts off this Genjutsu by forming a large quantity of hand seals, and gathering his chakra up behind him. This gives the impression of a powerful ninjutsu that is about to be used. To compound this fact, the user will finish the hand seals and expel the chakra in an outward manner, much like one would when utilizing a giant AOE (area of effect) jutsu.

After the chakra is expelled, the illusions starts. In order to help achieve this effect, the expulsion of chakra is laced with wind chakra, creating biting winds that whip up sand and dirt, normally causing the opponent to close their eyes. If the dirt/sand does not bother then, the wind will still force their eyes shut, as it is a quick, very cold burst.

Once the opponents eyes open again, they are struck by a sudden darkness, seemingly night all of a sudden. This would give the impression of a Genjutsu and be very easy to break if the next effect did not occur. After appproximately 5 seconds in darkness, the sky will light up, showing the battleground exactly as it was before the wind and the technique started, with one glaring exception. The user of this Genjutsu is standing in the middle with his arms raised, seemingly crying out to the heavens. Above the user, the sky will appear littered with multiple shooting stars, a sight that will distract the opponent (or ally as this affects everyone) for a split second. This does nothing for the battle.

The shooting stars will then appear much closer than before, and the target will get the horrible feeling that something is wrong, very wrong. The first meteor will then crash into the ground off to the side of the battlefield, giving off the impression of an immense impact with the earth shaking. A distant scream of howls will sound from the impact zone; unearthly, demonic like.

As more and more meteors crash into the earth, more howls are heard, and one post after the first meteor crashes, the secondary effect of the Genjutsu will take effect.

Demonic, misshapen, horrendous creatures will emerge for the shadows, stumbling along with broken limbs. Some fall down and die along the way, others ignore their injuries and head toward the target. These creatures taken the image of the worst combination of things that the target can think of, making them seem precisely what they should seem like; not creature from this planet. The eyes will glow with the same green fire that the impacting meteors are covered in.

By the third post, the shadows will begin to grow hands, an influence that seems like it is from the radiation and abilities of the meteor and the creatures it carried down. It is by this time that a person specializing in Genjutsu will notice that it is a Genjutsu. Should the opponent attempt to break free without utilizing the correct terms, the Genjutsu will not end, having not been adequately dispelled, and will continue to attack the opponent.

If the target does not release the Genjutsu correctly, the hands will grab on to the target, holding them in place and keeping them from running while the creature approach them, and begin to devour the target alive. By the end of the 6th post, should the target still not be released, a meteor will crash down upon the target. This will, essentially "kill" the target in their mind, leaving them within a comatose state beyond repair when the illusion is removed.


Name:Creation

Effect: This is the 5th tails ability. It allows the user to create an illusion on the spot, manipulating the 5 senses of their opponent in any way they wish. However, the opponent has a chance of realizing they are in an illusion and breaking out (at the cost of an A-Rank Genjutsu) if they scenery changes too drastically at first. This does not need any hand signs to make, nor a focus point due to the third tails ability.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Rokubi
Village of Origin: Kumogakure
Current Host and Village: -
Method of Sealing: -

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. The Jinchuuriki gains the ability to utilize the Raiton(Lightning) element.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• One Tail: By releasing this tail a haze begins to cover the Jinchuuriki’s body. The haze itself is the colour of the Raiton element; yellow for lightning. When this tail is activated the user is allowed to utilize any Raiton technique they know for a chakra cost one rank lower than the jutsu itself (Ie. B-Rank costs C-Rank).
  
• Two Tails: A second tail appears behind the user as the colors become more vivid and solid, instead of a haze, its more like a thick fog. The use’s body becomes harder to see due to the fog. When this tail is activated, the users Raiton techniques become stronger and hit a little big larger area (roughly 1 foot width and height all around). The chakra usage lowers by 1 rank. (Ie. B-rank costs C-rank).
  
• Three Tails: By activating the third tail, the user is granted higher speed that is equal to one rank higher. (Ie. Chuunin being as fast as a Special Jounin). It does stack with SC. Meaning if you have faster then the average ninja, it will stack with the speed boost. The user's hand speed is slightly increased, meaning it is harder to actually see (Even with the Sharingan).
  
• Four Tails: When this tail is activated, the user’s body is covered in a muscular and organ system, held in place by a yellow, orange with light blue chakra. The user can now activate Raiton techniques below Rank C with no chakra cost.
  
• Five Tails: The bones have formed around the weasel like creature.
  Handseals are now no longer used to activate Raiton jutsu, and now the user can no longer activate any other type of jutsu except Raiton.
  
• Six Tails: Full Release Now the beast is covered in skin and fur, actually looking like a really big weasel. C-rank and below techniques no longer drain chakra, and handseals for any ranked raiton jutsu no longer apply, for they have paws, not hands. The user is now tripled in speed. They are faster then most, only ones on par, are god like shinobi in speed, and very few other bijuu.

Unique Jutsus:

Name: Imari - Menacing Ball

Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Rokubi’s case, they are yellow-coloured chakra blast. This is available from the first tail.

Name: Lightning Claw

Effect: The user swings their arm and it forms a claw in chakra and releases 4 lanes of lightning bolts. At higher ranks where the tails are releases, the need to form the chakra claw is taken out. And the lightning is increased slowly by power. This is available from the first tail.

Name: Static Fur

Effect: The fur at the end releases small unnoticeable static in the air. That hurts people in a 15 foot radius of the user. The static feels like touching a electric fence. This is only available at the sixth tail.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Shichibi (Seven Tailed Badger Beast)
Village of Origin: Underground Sacrificial Altar in the Nagoya outskirts
Current Host and Village: ----
Method of Sealing:
Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. Transformation (Henge), Clay, Earth element. Can control any earth jutsu, even if earth is not the host's element. Has to be taken into thought though the rank of the host vs the rank of the jutsu he can use.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage. The Jinchuuriki can go underground and move around as he wants from the first tail stage and up. Also he can use clay attacks, which will be put in the jutsu list. Additionally, the host can transform into any type of creature as long as there is clay around. Can only hold the transformation up for 3 posts and has to wait 2 posts before being able to transform again.
One Tail: Dark blue chakra oozes around the host, forming a single tail and also acts as a defensive means. It layers upon the skin of the host, allowing his defense to become at least triple times higher than normally. In this stage, the user has some problems with sorting out his feelings, but all in all it seems that the Shichibi is the least chaotic one.
Two Tails: As the second tail appears through chakra, the host's speed increases along with his thinking becoming more clear. His skin now has become hard as iron, instead of the chakra layers protecting, but even so it doesn't slow the host down the least bit. He can also start calculating ahead in time, and overall feel 'smarter'. Claws appear instead of fingernails, long enough for the user to easily dig through the ground, and small fangs grow in his mouth.
Three Tails: At the appearance of the third tail, the host's senses have become much stronger. Allowing him to hear, smell and taste at a much improved rate. However, the hosts sight gets decreased. He can track anyone down now, even when using old trails just by using the basic senses. As the Shichibi seems to be more cunning and stealthy rather than hostile, so are the abilities of the Jinchuuriki more to the defensive manners.
Four Tails: When the fourth tail appears, the Bijuu has already started taking about 70% of the control. Due to it's cunning nature, it seeks to rather lure the host to it's side, tempting him with promising words to allow it to take more and more control. Random migraines start to come and go, as the host's thinking becomes much clearer but almost -too- much. He starts finding it difficult to clear his head and try to think about simple things, or notice the people around him.
Five Tails: As the fifth tail appears through the chakra, so does now more and more of the Bijuu's true nature start to show. It will coax, lie, cheat and do anything it can to trick the opponent. Already when having appeared this much, it has managed to swallow the consciousness of the host and will speak through him. When on this stage, if standing on a mud/clay/earth ground, the Bijuu is able to extract chakra from the opponent. See the jutsu list for rank.
Six Tails:
Seven Tails: At the release of the seventh tail, the host has already fallen into the grip of the Bijuu. It has taken completely over, and moves now underground. The host's appearance is the same as of the Bijuu, a blue badger. It's main attack form is to come from underneath the ground, breaking it up under the feet of the opponent and swallowing them up whole. If it manages to even bite any opponent or summon or pretty much anything, it is impossible to break free from it's hold because of the bodily structure of a badger which makes it not possible to even dislocate their jaw.

Unique Jutsus:
Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Nibi’s case, they are blue-colored fire blasts.

Name: Earthquake
Effect: While at the 5th stage of tail release, the Jinchuuriki slams down the 'tails', causing the earth around him in about 40 meter radius to vibrate violently and crack. The force would be that of an A rank, so wind would blow strongly in the radius of 10 meters around the host when it slams the tails down.

Name: Chakra Consume
Effect: At the range of 10 meters radius, and only on 'earth' (not water, snow, sand etc), the Bijuu can start consuming the chakra of the opponent/s. It travels simply through the ground and to the Bijuu.
From a Genin it can take 2/3 of the chakra
From a Chuunin it can take 1/2 of the chakra
From a Jounin it can take 1/3 of the chakra
From a S rank ninja it can take 1/4 of the chakra

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Hachibi (Eight headed and eight taled snake beast)
Village of Origin: An old battlefield in Osaka
Current Host and Village: ----
Method of Sealing: A forbidden sealing method only to be used by the Yagami clan

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. Also the eight heads of the Hachibi each represents a symbol; Soul, Ghost, Evil, Devil, Monstrous, Kill, Afterlife, and Death. And with each tail that manages to appear on the Jinchuuriki (along with head), so can he control these symbols.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage. The host cannot use all eight symbols at once (or techniques that come with the tails), but rather is limited down to a certain number depending on his / her rank. This preventing the host from either dying or going mad from the overuse of power. A Genin can activate a single symbol, a Chuunin can activate 2 symbols, a Jounin can activate 3 symbols and a ninja of the S rank could activate 4 symbols.

One Tail: [Genin +] Soul. The Jinchuuriki starts oozing a dark colored chakra, which seems though to sometimes flicker to the color of ice blue. This chakra takes on the form of not only a tail, but also a snake head. His skin starts turning into a dark grey color while seemingly no other changes are made to his physical appearance. The oozing chakra will burn at contact, but not with the help of the Katon element but from the dark chakra of the Hachibi demon. In this state, the Jinchuuriki can manipulate spiritual energy beyond the chakra which resides in his own body or the body of his Bijuu. Allowing him to manipulate the nature elements around him, being able to release and mold elemental chakra without having to use his own energy. The downside of this being that he takes damage to his skin each time he uses the ability, it burning and getting teared off as if it was being burnt by a touch of flame. The host acts mostly out on the ruling emotions now, not much sense being able to enter his mind.

Two Tails: [Genin +] Ghost. Another tail and head appear, the chakra only remaining black now. The skin of the Jinchuuriki has now turned completely black, as have his eyes turned red and there can be a slight hint of fangs starting to grow. Through the act of using this symbol, the Jinchuuriki can mold elements and also gather energy from the dead bodies of animals or people. When in a battleground this is a crucial ability. Each usage of this though does the same damage to the Jinchuuriki's skin as when using the elements from nature itself. Now the host starts to slip a bit more, getting more reckless with each action as he starts to see enemies in friends.

Three Tails: [Chuunin +] Evil. Appearance of the third head and tail. The fangs of a snake have now completely come forth, and the skin has a scaley kinda look to it. This stage dwells heavily within the realm of the metaphysical. But instead of dealing with the 'supernatural' like the previous ones, it deals directly with the chakra of the Bijuu. This stage unlocks an even greater stores of chakra than what is normally accessed from the Bijuu, so that now the Jinchuuriki's chakra has been completely restored with the Bijuu's chakra, meaning he has now dark chakra flowing within his system. However, Hachibi's chakra is too large for one human body to handle at once, and that's why the seal manages the amount of the chakra flowing into the Jinchuuriki's body. This sudden surge of chakra allows the user's strength to triple up, but with each usage of technique in this state the user risks a cardiac arrest. Overuse from this stage and the monstrous strength, will result in the user at least fainting at the battle field. This stage puts an enormous strain upon the host's heart due to the sudden release of great chakra from the seal upon it. The host will now attack anyone that will get in his way, although with enough willpower he might be able to stop off an attack on a loved one.

Four Tails: [Chuunin +] Devil. Fourth head and tail appear through chakra manipulation. Also the host has no single shape by now, the chakra having wrapped around his body so that another image seems to have formed. Blood from where skin has peeled off seeps into the chakra. While other Bijuu's abilities would allow the user to heal, then the Hachibi's devil art allows for the reconstruction of genetic materials on a cellular level. And thus, allows the user to morph his body, reconstructing it into numerous forms; Shape shifting. This stage allows the user to go beyond the usual shape shifting or body transforming, allowing him to shift his body to take more aspects of the Snake Bijuu itself. Letting hard scales that can take immense damage grow on his skin, or let claws grow that could rip through the hardest armor. But when using this ability it should be noted that if the user isn't careful, this ability can skew out of control and leave the host's molecular structure damaged. Physical pain along with physical fatigue are also endured with each transformation. This limits the amount of time any 'transforming' techniques can be used, and also for how long they can be used. The host doesn't care now if he attacks his parents or enemies for that matter. He wont be able to think like a human much more, and will seek to cause as much destruction as possible. When coming out of this stage, it will take him a few hours before he can mold chakra again as will he need to rest for a week without straining his body much.

Five Tails: [Jounin +] Monstrous. Fifth head and tail appear through the chakra. The host is permitted the ability to summon forth snakes of various forms and powers. None of them possesses chakra nor any weapons or special abilities, but they have their bodies and fangs to attack. They differ in strength and size depending on the rank of the host. The summoning of these snakes not only results in chakra loss but also loss of physical strength, so the host should have to be careful of what he summons forth. The host is linked to his summons through a physical link, so each time a summon gets killed or injured, the host will experience hardship through them. Also, each summon possesses a sacrifice. Whether it is a loss of sense in one hand, loss of eyesight or smell etc. The snake summons will be put in a jutsu list below. Basic Summoning skill is not required for this. The Bijuu has started to come out more, it's own voice even echoing from the host. It has taken most of the control now, but if the host is strong enough he can fight back still. When coming out of this stage the host will need 2 weeks to recover, and a week before he can mold chakra.

Six Tails: [Jounin +] Kill. Sixth head and tail appear. Here, the user has the same ability where he can reconstruct his body and change his appearance, but however, in this case he will take on the form of those he has killed. He will get their strengths and abilities while at it. The host cannot use any other ability from the previous tails while using this stage. To use the strength of Kill encourages mental insanity as the user has to re-experience memories and grief along with the sorrow of the dead. If left unchecked, this stage can completely take the host over and he will most often commit suicide or simply never return back to his previous mind. Still being conscious, this stage can be a torture to the host. The Bijuu will dwell deep within his mind, searching for whatever it can use in the fight, as it doesn't matter to the Bijuu whether the living prison it is in goes insane or not. Anyone that will get in the way will get killed now, and if the user comes back from this stage he will be in a coma for 4 weeks and wont be able to mold chakra for a week after he wakes up.

Seven Tails: [S rank] Afterlife. Seventh head and tail appear. Now, the user starts getting a more and more snake-like image. His face narrowing down, nose disappearing into thin nostrils. This stage is one of the strongest one of the Hachibi. It does not offer much to the host though, other than the chance to exist within the spiritual realm. The host can use this stage to gain information of the spiritual world and see through the future and past. Doing so, will require much concentration though and if the user is not strong enough he will fail. Afterlife results in a chilling of the body, and strain upon the mind. The hosts thoughts are starting to drift more and more, while he cannot control his body at all, and if he gets out of this stage it will leave him in a coma for 2 months while molding chakra after he wakes up will take 3 weeks.

Eight Tails: [S rank] Death. The Bijuu has come through, completely changed the Jinchuuriki's appearance into it's own. A huge, the size of eight mountains, deep brown snake with eight heads and eight tails, along with crimson eyes. When using this stage, it is possible to exchange lives To be able to revive the loved one, but to have to send someone in his place. The last stage is a little bit of a cruel play for one who wants to play God. This however, being the final stage, means that the user has gone past his control over the Bijuu and most often the Bijuu itself will use a sacrifice to bring someone back to life. The host has no control anymore nor rational thinking for that matter. If the host comes back from this stage, he will not know who he is or was. He will be a different person, someone lost in his own mind forever.


Unique Jutsus:
Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In Hachibi’s case, they are black-colored fire blasts.

Name: First Stage Snake Summon
Effect: Sacrifice; The loss of smell and taste.
A snake of vibrant colors comes forth, it being only about 1 meter long and rather slim. If it manages to bite the opponent it will poison him.
Effects of the poison;
First round, same post as bitten: No pain will come from the bite nor will the opponent even know that he has been poisoned while the poison slowly starts running through his veins.
Second round, second post; The opponent's eyesight gets blurry as will his smell and taste buds get completely thrown off.
Third round, third post; The pain from the bite now starts to sink in, leading to the bitten victim to feel as if the spot they had been bitten on was being stabbed over and over again with knives. The pain leads up into the head, making their thoughts blurry and making it more difficult to think. Also the skin where they got bitten starts turning black.
Fourth round, fourth post; Blood starts dripping from the eyes, nose, ears, mouth and the bite marks. The opponent will start losing the feeling in the surrounding area of where he was bitten, and along with losing blood rapidly will have still the migraine from earlier along with all the sense being thrown off by the blood.
Fifth round, fifth post; Death. Unless having come up with an antidote, which can be extracted from the Jinchuuriki host himself as his own blood is immune to the poison, or if the opponent was lucky enough to have a skilled med ninja nearby.

Name: Second Stage Snake Summon
Effect: Sacrifice; The loss of hearing.
Twin white snakes, both about 3 meters long will appear. Their fangs will hold no poison, but their scales can withstand damage up to A rank attacks. They will not be killed unless hit on the same spot three times of the same amount of damaga/force as what would equal rank A+. If one snake dies, the other does also. They will seek to wrap around the opponent and crush him, be as a shield for the host, or destroy summons.

Name: Third Stage Snake Summon
Effect: Sacrifice; The loss of eyesight.
A brown snake of 10 meters comes forth, it being able to control a single element. It is completely random upon each time it gets summoned forth what element it can use. It can make 4 A rank elemental attacks, 6 B rank, 8 C rank and 11 D rank.

Basic Jinchuuriki/Bijuu Info
Tailed Beast: Kyuubi (Nine-Tailed Demon Fox)
Village of Origin: Konohagakure (Hidden Leaf Village)
Current Host and Village: Konohagakure
Method of Sealing: Birth

Spoiler:

Inherent Abilities: The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain accelerated healing.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased each stage.
The Jinchuuriki also begins to slowly become manipulated by the Kyuubi in each stage due to Kyuubi's personal malice.

• One Tail: The Jinchuuriki gains a visible aura of the Kyuubi's chakra, that works as a protection, including the shape of a tail. The Jinchuuriki can then create giant pure hands of red chakra to attack from a distance and can mix the Kyuubi's chakra within their own attacks. The Jinchuuriki's teeth and nails also become sharper.
  
• Two Tails: The aura becomes more concentrated, and a second tail appears.
  
• Three Tails: The aura becomes more concentrated, and a third tail appears. During this form, the air around the Jinchuuriki begins to sting anything touching it besides him or her. A simple roar can create a ball of destruction.
  
• Four Tails: A fourth tail will form in this form while the chakra becomes solid; making the Jinchuuriki appear red and black due to being covered in not only chakra but the Kyuubi's blood. In this stage, the Jinchuuriki's epidermis is constantly being burned off and healing; shortening the Jinchuuriki's life. In this form, a simple wave of the hand can cause a wave of destruction. At this form, the Jinchuuriki can charge a concentrated ball of chakra, consume it, and fire it in the form of a massive blast of chakra with a powerful force.
  
• Five Tails: The aura remains solid, a fifth tail appears, and the Kyuubi's some bones begin to form out of chakra on the Jinchuuriki's back.
  
• Six Tails: A sixth tail emerges along with more bones; along with several thick ligaments. In this form, unlike the four tailed one, the Jinchuuriki can release a concentrated ball of chakra without ingesting it and with more force.
  
• Seven Tails: The Jinchuuriki earns a seventh tail, the full skeleton emerges, and muscle tissue begins to form on the Jinchuuriki.
  
• Eight Tails: The Jinchuuriki becomes surrounded in the Kyuubi's muscles while gaining another tail. This form is the largest form, about the same size at the Kyuubi itself.
  
• Nine Tails (Full Release): The seal is broken and thus the Kyuubi becomes unleashed into the world and the Jinchuuriki's body is completely taken over.
  

Unique Jutsus:
Name: Bouei – Protection
Effect: In each stage the Kyuubi provides the Jinchuuriki a stronger form of chakra shield and various chakra oriented attacks.
The chakra shield, in first tail form, is enough to protect the Jinchuuriki from simple jutsu (D rank and below) and physical attacks. The Jinchuuriki can even form a giant hand of chakra to attack. In fourth form this shield then becomes solid and begins to burn the Jinchuuriki's skin off; showing just how protective it is. Not only this, but if attacked another body will manifest out of the Jinchuuriki and attack back. The Kyuubi's bones and muscular system surround the Jinchuuriki in the later tails.

Name: Chiyo – Healing
Effect: This inherent ability allows the Kyuubi‘s host to naturally heal their body over a short period of time from even fatal wounds.

Name: Imari - Menacing Ball
Effect: The Jinchuuriki's ability to manipulate pure chakra energy into a projectile blast. In the Kyuubi's case, this ball can first be used in four tail form where the Jinchuuriki charges a concentrated ball of chakra before ingesting it and releasing it in a powerful blast. In Eight tail form, the Jinchuuriki will no longer have to ingest this ball and can release even more devastating attacks.
