While this mode is active, the user gains a chakra shroud with six magatama markings around their neck, two distinctive horns resembling the Sage of the Six Paths' silhouette, swirl designs similar to the Uzumaki clan's symbol, and various other lines extending along their body. Minato's shroud had six additional magatama markings around the collar of his mantle as well as patterns extending from his sleeves to the palms of his hands, the latter of which can also appear on Naruto's shroud at times.
The user's eyes become orange when in this mode and whereas the demon fox cloak is red and releases chakra as boiling bubbles, this form's shroud is yellow and releases chakra as flickering flames. While in this form, Naruto's chakra signature and smell are different, as noted by Neji Hyūga and Kiba Inuzuka respectively. In the anime, a slight dark aura is seen covering Minato's chakra cloak.
Two years later, with both halves of Kurama now sealed as a whole inside him, Naruto's appearance in this form changed again. His chakra mode's markings now has a more simplistic design with thicker lines, two of which wrap around his collar above the six magatama. His centre also has a single dot with a partial circle around it opening at the top and six lines stretching out from it; two of which spread down his legs where the part and wrap around his feet. The other two lines wrap around his waist that connect behind him next to a circle on the centre of his back.
Years later as the Seventh Hokage, Naruto's Chakra Mode changes again. Similar to his Kurama Mode from during the war, his upper body gains an inverted colour-scheme where his shirt turns dark while the lines turn bright, along with the circle on his abdomen being full. His cape also gains similar circle marking around the shoulder area. He also regains the markings on the back of his hands. His six magatama around his collar also seem to be missing.
