Han's Jinchūriki Forms

Han is the jinchūriki of the Five-Tails. Not much is known about Han or his tailed beast, but in the anime, it was stated that he detested humanity because they shunned him due to being a jinchūriki. Han was eventually captured by Akatsuki and his tailed beast extracted, causing his death. However, during the events of the Fourth Shinobi World War, he was resurrected and made into a jinchūriki once again, yet the Eight-Tails remarked that his tailed beast felt "different".

Version 2
Whilst resurrected, Han displayed the ability to enter a "Version 2" form, by moulding the Five-Tails' chakra into a human-like shape around himself. When entering into this form, the sudden increase in chakra was such that it instantly vaporised Killer B's ink clone, which had immobilised him at the time.

In addition to forming a dark chakra cloak around his whole body, which also surrounded the entirety of his Steam Armour, he gained the characteristic horns of the Five-Tails atop of his still visible hat and a prominent hump on his back, due to the presence of the armour's furnace, although, it seems he does not have his mask that is part of the armour. With the power granted by this form, Han manifests all of his beast's five tails.

Partial Transformation
After being resurrected, Han demonstrated the ability to manifest one of the beast's tails.

Full Five-Tails Form
While fighting Naruto Uzumaki and Killer B, Tobi forcefully transformed the revived Han into his full Five-Tails form. In this form, he takes on the appearance of the Five-Tails itself, allowing him to utilise the beast's horns to wound and repel even a fully transformed B. However, soon after assuming this form, the Five-Tails was able to briefly regain control of itself, despite Tobi's influence.
