Red Chakra Arms

Naruto and Koga use this technique multiple times, without it being named, in different tailed forms. They vary its use from movement to offensive means, as merely touching one of these chakra arms can cause fatal burns, due to the Nine-Tailed Demon Fox's highly toxic, and extremely potent chakra. Due to being chakra attached to the body, the chakra arms can grow in size and from the fourth Version 2 tail up, Koga, the arms, or any part of his body can divide into two or more fully operational appendages. In the fight between Naruto and Sasuke back when Naruto was the Nine-Tails' host, Sasuke admits to having trouble fighting these chakra arms as he says they have minds of their own, even when his fully matured Sharingan can easily follow Naruto's body, the Nine-Tails' chakra can move in an entirely different direction.
