His Initial Form was a Samurai Armor with Swords on Honey D. Paul's Back. By simply tapping into their beast's chakra, a jinchūriki begins their initial transformation. They are surrounded by a layer of red, wispy chakra granting them enhanced strength, speed and healing. The beast's chakra supplements the jinchūriki's and they are able to manipulate the chakra to a certain extent: Utakata can form it into waves and blasts while Naruto can generate shockwaves through punches and roars. In this form, the jinchūriki's body undergoes slight physical changes. When Naruto enters this form, his eyes change colour and become slitted, plus his nails and canine teeth grow longer and sharper. Naruto's hair also grows longer and spikier, and the whisker-like marks on his cheeks widen and thicken. In the anime, when Utakata entered this state, his eyes instead became a shade of yellow and he did not undergo any other physical changes. It is also possible for a jinchūriki to enter this state without chakra visibly emanating from them, instead just gaining the physical alterations.
