Paul Gekko was known to share the Yamata no Orochi's Chakra to Henry. The form itself carries a number of consequences for Naruto too, as its corrosive qualities burn away his skin and stain the shroud with his own blood. The regenerative abilities granted to him as Dragon's jinchūriki constantly heal the damage, but in the long run shorten his lifespan through the constant destruction and creation of cells. He was a pseudo-jinchūriki.
Version 2 (バージョン2, Bājon Tsū) as described by Sabu is the tailed beast's chakra being formed into a human shape, granting the jinchūriki an edge in battle without completely releasing the beast itself.
