All Jinchuuriki can learn the following techniques on their characters though they will take up jutsu slots to have and use:

Name: Jinchuuriki Chakra Cloak - Stage 1
Rank: C
Type: Ninjutsu
Element: Chakra
Description: Grants a Speed + Strength + Chakra Capacity boost (1 level), minor damage reduction, tails start showing and your physical form is still visible through the chakra. By calling on the chakra of their Bijuu the Jinchuuriki Forms a dense shroud of chakra around the jinchūriki. The shroud, a translucent red with bubbles of chakra (reminiscent of boiling liquid) 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 Gyuki, chakra-horns form on his head. Because chakra is malleable, the shroud can extend beyond the reach of the jinchūriki, often used to create chakra-arms that allow them to interact with their environment.

Name: Jinchuuriki Chakra Cloak - Stage 2
Rank: B
Type: Ninjutsu
Element: Chakra
Description: Grants a Speed + Strength + Chakra Capacity + Endurance boost (1 level), Moderate damage reduction. Using the jinchūriki's body as a sort of endoskeleton, a dark red, nearly black layer of chakra 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 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 and furnace that Han 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 chakra-arms, are still accessible. It is even possible for the jinchūriki to create chakra-bones around themselves.

Name: Chīsai Bijuudama - Small Bijuu Ball
Rank: B
Type: Ninjutsu
Element: Chakra
Description: Chīsai Bijuudama is a Ninjutsu capable of being created by skilled Jinchuuriki and their Bijuu. First the Bijuu will expel positive black and negative white chakra particles from their body. These small orbs will then be compressed into a small ball of chakra in an 8:2 ratio of black to white chakra that can then be thrust at or thrown at their enemy. The Jinchuuriki can also choose to ingest the Bijuudama and fire it out as a concentrated beam of destructive power. This technique is far smaller and weaker than it's fully evolved version, and will require a user to have their stage two cloak to be able to use.

Name: Jinchuuriki Partial Transformation - Stage 3
Rank: A
Type: Ninjutsu
Element: Chakra
Description: Grants a Speed, Strength, Reflex, chakra capacity, and endurance boost (1 levels), Moderate damage reduction. The Jinchuuriki starts taking an incomplete transformation of their Bijuu, be it actual partial tails, wings, or a hideous skinned fox like appearance. You are still at your same physical size but portions of you are the same as your Bijuu.

Name: Jinchuuriki Full Transformation - Stage 4
Rank: S
Type: Ninjutsu
Element: Chakra
Description: All of your physical stats gain a 1 level boost, and you transform growing in size to the full indomitable form of your Bijuu in all of it's impressive majestic glory. You are the size of most boss summons and able to level some small villages with a thought. But remember your capabilities are your own, so if you are a wimpy wimpy twig boy people will be able to stop your attacks even though you be massive.
