Bijū Form (Nine-Tails Version)

The Bijuu Form (Naruto Version) is a unique transformation of the Nine-Tails jinchuriki, in which a full-size translucent golden copy of Kurama with black lines across the entire body forms around the user. Unlike the usual tailed beast mode, there is no physical transformation into a monster here: Naruto or Minato hover inside the head of the chakra avatar, retaining the ability to use any of their techniques - from the Rasengan to shadow clones - and even extend tails as arms made of chakra. Kurama can speak through this form and gain control over it.

This is the completed stage of the Nine-Tails Chakra Mode, granting access to Tailed Beast Bombs. Naruto could initially maintain the form for only five minutes due to his imperfect bond with Kurama, but over time increased the limit to eight minutes. Allies can be let inside the avatar, where the fox's chakra heals their wounds and restores their strength.
