The person injected with these snakes can also force the snake out, and drink the chakra directly, vastly increasing their chakra and power, as well as inducing a body-mutating transformation (in Gitai's case, he became an Asura-like entity, with three faces, six-arms and a tail), but results in their body being highly unstable. The dark chakra snakes can also be used against the opponents. By injecting them with the same chakra, it can either paralyse or kill without leaving a mark.
