All jinchūriki are able to use certain abilities granted to them by their tailed beasts. As they get older and they gain (or lose, as the case may be) control over their tailed beast's power, they are also able to transform into their tailed beast to varying degrees, granting them capabilities increasingly closer to the tailed beast itself.

Initial Jinchūriki Form Edit

  • Known users: Toby Tripp, Nick Tripp, Jessica Herleins, Lucas Wanson, Gina Louren, Kai Sanders, Plezuon, Agrom Maxwell, Noctis Williams, Piron Tadashi, Tasaru Daegan, Soleanna Blaze, Glacieall Vasilyev, Zapus Santos, Cyro Zhang, Deron Tadashi, Zak, Cloe, Kiet, Fenzy, Lon, Thomas, Xander, Finn, Jack Fuego, Travis/Leomon/BanchoLeomon, Tampo, Kento, Lalith, Hamato Yoshi/Splinter, Leo, Raph, Donnie, Mikey, Lynn, Shiro, Mook, Yuna, Kogenta, Grey, Theo, Ashley Mira, Aster, Master Noran, Keith, Lance, Pidge/Katie, Hunk, Allura, Edward Elric, Alphonse Elric, Jason, Ellie, Matt, Marty, Ally, Ciel, Rex

By simply tapping into their beast's chakra, a jinchūriki begins their initial transformation. They are surrounded by a layer of randomly colored wispy elemental energy granting them enhanced strength, speed and healing. The beast's energy supplements the jinchūriki and they are able to manipulate the energy to a certain extent: Toby and Cloe can form it into waves and blasts while Nick and Zak can generate shockwaves through punches and roars. In this form, the jinchūriki's body undergoes slight physical changes. When the Lords of Nature and the Sendokai Warriors enters this form, their eyes change colour and become slitted, plus their nails and canine teeth grow longer and sharper. Their hair also grow longer and spikier. When Lon entered this state while being Grezar's Jinchūriki then Gregar's JinchūrikI, his eyes became a much darker shade of red than normal and his canine teeth and nails grow sharper with purple lines on his eyes and purple markings on his body. It is also possible for a jinchūriki to enter this state without energy visibly emanating from them, instead just gaining the physical alterations.

Version 1 Edit

  • Known users: Sendokai Warriors, Plezuon, Lords of Nature, G-Fighters, Voltron Paladins, Allura, Ichigo Kurosaki, Natsu Dragneel, Conan Edogawa/Jimmy Kudo, Goku, Gingka Hagane, Eli Shane, Maka Albarn, Monkey D.Luffy, Geo Stelar, Jak, Ratchet, Ben, Haru, Jack, Hiro, Matt, Ryuko, Ikki, Saitama, Genos, Lance (Manus), Ilana, Neon Force

Version 1 – or what Kento calls Zak's "fire dragon cloak" – forms a dense shroud of elemental energy around the jinchūriki. The shroud, a translucent color that represents the Jinchūriki with bubbles or attributes of elemental energy (reminiscent of boiling liquid and many elements) forming all along it, provides a degree of physical protection, but can also harm the user if used to a certain extent. The physical changes experienced in the initial transformation become more pronounced in Version 1 forms.

The shroud that encompasses the jinchūriki vaguely resembles the corresponding tailed beast; paws of chakra form around their hands and, in the case of Kiet, energy-horns form on his head. Because elemental energy is malleable, the shroud can extend beyond the reach of the jinchūriki, often used to create elemental energy-arms that allow them to interact with their environment. The most significant manifestation are the tails that sprout from the jinchūriki's body, up to the maximum number of tails that the corresponding beast possesses. As with the elemental energy-arms, these tails can aid the jinchūriki by grasping to their surroundings. For each tail produced, the jinchūriki gains an incrementally greater boost to speed, strength, and energy.

The source of the energy shroud differs between users. For jinchūriki who have not learned how to control their tailed beast, it is the beast's energy that surrounds them. The beast's energy will tend to be harmful: individuals near the jinchūriki will experience a slight physical discomfort; those who come into contact with the shroud will suffer a painful burn or injury depending on the element wherever they touch it; the jinchūriki themselves suffer an increasing amount of corrosion to their body that can eventually damage body parts beyond the point of use. This shroud is typically acquired through a growing rage and/or the weakening of the seal that keeps the beast within their body, and consequently leaves the jinchūriki less in control of their body with each additional tail. While a jinchūriki has never been observed to completely lose control of themselves in a Version 1 form, they become more animalistic and aggressive. One advantage of this is that the shroud can act on its own, responding to threats the jinchūriki may not be aware of.

A secondary means of entering a Version 1 state is demonstrated by Leomon and Tampo, who used their own energy in the shroud's formation. While Toby has been able to communicate with Nerozar and ask for a donation of energy for recharging himself and his friends, this always carried adverse consequences such as diminishing self-control and harmful after-effects of the energy. After the Warriors and the Lords befriended their beasts, these drawbacks were removed and they can use Version 1 for themselves, and is able to transfer it to others, thereby granting them all of the form's benefits. The energy in this form is also capable of repelling the likes of Grezar's lightning blasts.

Version 2 Edit

  • Known usersSendokai Warriors, Plezuon, Lords of Nature, G-Fighters, Voltron Paladins, Allura, Ichigo Kurosaki, Natsu Dragneel, Conan Edogawa/Jimmy Kudo, Goku, Gingka Hagane, Eli Shane, Maka Albarn, Monkey D.Luffy, Geo Stelar, Jak, Ratchet, Ben, Haru, Jack, Hiro, Matt, Ryuko, Ikki, Saitama, Genos, Lance (Manus), Ilana, Neon Force

Version 2 (バージョン2, Bājon Tsū), as described by Tampo, is the tailed beast's energy being converted into a humanoid shape, granting the jinchūriki an edge in battle without completely releasing the beast itself. Using the jinchūriki's body as a sort of endoskeleton, a dark color (matching the Jinchūriki's color), nearly black layer of energy envelops them. The physical manifestations of the corresponding beast that are vaguely present in Version 1 states become far clearer in Version 2, in a way fully reproducing the beast in miniature: muscle mass increases and beast-specific attributes such as wings, spikes, fins, shells and ears become clearly defined. Because the shroud forms so tightly around them, features of the jinchūriki may be identifiable in Version 2, such as the hat that Luffy wears.

Entering Version 2 creates a great deal of energy, producing craters beneath the jinchūriki and destroying any restraints that might have been placed upon them beforehand. Strength, speed, and chakra are once again increased beyond the levels of the previous forms, the shroud remains a reliable defence against attacks, and other features, such as elemental energy-arms, are still accessible. It is even possible for the jinchūriki to create elemental energy-bones around themselves: Cyro creates a bull's skull in order to perform a more powerful Metal Release: Metal Horn Charge; The Warriors or the Lords, on different occasions, form full skeletal structures in differing states of completeness all along their bodies that are attached to them by elemental energy-ligaments, but the bones serve no obvious purpose.

Most jinchūriki have only been seen to enter a Version 2 state with the same number of tails as their corresponding beast. Lalith represents one exception in that not only she does not have a full set of 12 tails, but one tail remains far longer than all the others. the Lords of Nature, the Sen-Kuns, Marty, Geo, the Paladins and Allura is also an exception, for they have only been seen in Version 2 states with four and six tails (and seven tails in the anime). Unlike how the number of tails in Version 1 can measure the jinchūriki's strength, there is no observable correlation between the number of Zak's Version 2 tails and his destructive capabilities. Likewise, although all jinchūriki gain unique, heightened abilities that bring them even closer to their corresponding beast.

The Warriors and the Lords have yet to knowingly enter Version 2 forms. As the seal that kept their beasts contained weakened over the years, they became increasingly susceptible to its influence. By fully submitting to the beast and their own stress or Zak's or Keith's case, their rage, they would grant their dark sides full control of their bodies who then formed a Version 2 shroud around him. Their ability to distinguish between friend and foe vanishes and they attack in whatever way will enable them to defeat their target, oblivious to the consequences of the attack. The form itself carries a number of consequences for them too, as its corrosive qualities burn or rip away their skin and stain the shroud with his own element. The regenerative abilities granted to them as their jinchūriki constantly heal the damage, but in the long run cause them to gain random scars on their bodies through the constant destruction and creation of cells. In the third season, Lon learned to instantly access this form at will and retain complete control of himself, including to change back to normal whenever desired without suffering any damage. Plezuon's Version 2 is also triggered by rage or sadness as well and causes the same kind of damage to her body. Soul appears to trigger Version 2 through rage as well, but he retains control of his mind and do not seem to suffer any damage to his body.

Partial Transformation Edit

  • Known usersSendokai Warriors, Plezuon, Lords of Nature, G-Fighters, Voltron Paladins, Allura, Ichigo Kurosaki, Natsu Dragneel, Conan Edogawa/Jimmy Kudo, Goku, Gingka Hagane, Eli Shane, Maka Albarn, Monkey D.Luffy, Geo Stelar, Jak, Ratchet, Ben, Haru, Jack, Hiro, Matt, Ryuko, Ikki, Saitama, Genos, Lance (Manus), Ilana, Neon Force

Rather than fully transform into their respective beast, a jinchūriki can isolate the transformation to parts of their body. Instead of appearing as translucent or dark energy, these partial transformations fully resemble the beast's own limbs, having fur, feathers, scales, etc. The dark jinchūriki created and controlled by Lon each briefly produce a tail of their respective tailed beasts. 

Leomon (later BanchoLeomon), Tampo, Kento and Lalith made a much more deliberate usage of the body parts they choose to partially transform. They often produce extra tails to increase his ability to interact with others and his surroundings as well as to improve his dexterity. Leomon has transformed one of his arms at different times, either to increase the distance that he was able to throw or to block a punch.

The Sendokai Warriors and the Lords' partial transformations have been the most substantial of those seen. In order to break free of the whatever traps them, they entered states just short of a full tailed beast-transformation (which, at the time, would have required completely breaking the seal or unlocking their true potential); the only features it lacked to fully resemble their beasts were the last required tail, skin, and scales, feathers and fur, their transformations otherwise matching the beast's sizes and possessing all of the other elemental energy-body parts. After becoming able to harmonise with their beasts, their partial transformations are less drastic, producing only tails like the other jinchūriki tend to or a head for attack.

Shukaku's Original Jinchūriki represents an anomaly in the pattern of jinchūriki partial transformations. Whereas all other jinchūriki's transformations are composed of energy, Shukaku's Original Jinchūriki is made of sand. He gradually piles sand onto his body, giving him an increasingly closer similarity to Shukaku with changing eyes to match. In many ways it is similar to Version 1 forms: his defences are nigh-impenetrable wherever the sand is applied; he can stretch his sand-limbs beyond their normal reach; the more his body is covered with sand, the more his speed and strength grow. Being sand, he can detach parts of his "body" from himself that will retain their shape for as long as he exerts the chakra to maintain them. However, this has been changed when Ichigo seals Shukaku inside of him, which makes him transform like other Jinchūriki. Although he goes to this process if necessary.

Tailed Beast Mode Edit

  • Known usersSendokai Warriors, Plezuon, Lords of Nature, G-Fighters, Voltron Paladins, Allura, Ichigo Kurosaki, Natsu Dragneel, Conan Edogawa/Jimmy Kudo, Goku, Gingka Hagane, Eli Shane, Maka Albarn, Monkey D.Luffy, Geo Stelar, Jak, Ratchet, Ben, Haru, Jack, Hiro, Matt, Ryuko, Ikki, Saitama, Genos, Lance (Manus), Ilana, Neon Force

In principle, all jinchūriki can fully transform into the tailed beast sealed within them when the seal breaks and they entirely lose control over the beast. However, doing so results in the jinchūriki ending up unconscious and weakened. Tailed Beast Mode(尾獣モード, Bijū Mōdo), also called Tailed Beast Transformation (尾獣化, BijūkaEnglish TV: Tailed Beast State), is a way to avoid this. By either subjugating their tailed beast or learning to work in unison with it, a jinchūriki can become a full-scale replica of the beast with complete access to its natural strength and abilities. If they choose, the jinchūriki can pass control of this form to the beast itself.

Tailed Beast Mode is devastatingly powerful and poses an untold risk of collateral damage. It is for this reason that Plezuon, Travis, Tampo, Kento and Lalith were forbidden to use the form under normal circumstances, as it could easily destroy an entire town if left unchecked. The most dangerous and powerful ability available to this mode is the Tailed Beast Ball.

Cloe is seen willingly transforming into Tigrora to save Zak after she bonds with Tigrora. Her size in this state was far smaller than when BlackShoutmon cloned her dark transformation during the war but she now has her true number of 7 tails and full power, the exact amount of control she has is unknown. That said, in the anime the original Cloe seemed to be able to transform with very little effects to herself as she was able to provide a paw print for Tampo's Paw Encyclopaedia. Also in the anime, Eli was able to fully transform into Saiken to help the Warriors fight against Blakk's new Ghoul Chimera after asking for the slug's aid and bonding with it.

The Warriors, the Lords and the Voltron Paladins have not been able to fully recreate their Beast's forms. At first, this was because the beasts doesn't know how to cooperate with them, causing all attempts to turn into it to result in miniature, comical versions of the beasts that could not be maintained for very long. Since then they have been able to earn their cooperation, but the Tailed Beast Mode they enter, though accurate in size, is unique as he does not as closely resemble the beast as the other jinchūriki do their own. For more on their versions of this form (and The Original Warriors and Lords'). Also unique to the team, when accessing Sage Modes while in their Tailed Beast Modes, thier elemental avatars of their beasts gains the rings around their eyes. They retain this mode even when they has their Elemental Mode, with their beasts' avatars becoming many times larger and more powerful than before and retaining the circular marks around their eyes as well gaining their signature symbols. By combining their beasts' avatars with other two created through shadow cloning, they can manifest forms similar to the one Old Sage wielded. When they are unable to fight when BlackKingShoutmon mode locks them in their original fighting forms, they bond completely with their beast and finally transforms into their Beast Forms to fight EclypseShoutmon then unlock Neo Sage Mode to defeat him and now they transform whenever a very powerful enemy is beating them.

Ichigo's Tailed Beast Mode is also unique but the difference between him and Gaara is that Ichigo transforms like other Jinchuriki as well; but unlike the other jinchūriki or the team's, his is composed of sand that can entirely shatter if Ichigo is knocked out, and it takes quite a bit of time for Shukaku to gain its full strength in the form whenever Ichigo uses the Sleep Technique. As such, it can't use the Tailed Beast Ball immediately, instead focusing on its other powers such as its sand control or its Wind Release: Drilling Air Bullet.

Provided the jinchūriki is also a sage, they can gather natural energy at an extremely fast rate to the point they only need to remain still for a few seconds to fully replenish their powers.

In Sendokai Champions: the Demon Within, The Lords manifests The Original Lords outside of their bodies to aid in their battle against Neo Dark Cloe.
