Kinkaku's Jinchūriki Forms

Despite not being a jinchūriki, Kinkaku, like his brother Ginkaku, absorbed a massive amount of chakra from the Nine-Tailed Demon Fox, as well as eating some of its chakra flesh, while being trapped in its stomach. Thus, they can have access to powers and abilities similar to that of Naruto Uzumaki.

Six-Tailed Form
While enraged, Kinkaku can access a massive amount of Nine-Tails' chakra, enough to enter a more muscular version of Naruto's four-tailed form, but with six tails. However, unlike Naruto's six-tailed form, it lacks the Nine-Tails' skeleton and Kinkaku seems to retain his consciousness. The power of this form revolved mainly around it's abnormally long middle tail. With it he could smash entire cliffs to pieces and agitate the ocean enough to create waves, as well as block a torrent of kunai, throw aside a giant rolling tank, and break out of the Shadow Imitation Technique.
