As the jinchūriki of the Six-Tailed Slug, Rokubi can use the Six-Tails Chakra to increase his strength and coat himself for defense and protection. This is possible as the slug implanted itself within Rokubi's subconscious via telepathy and was considered sealed with Yang Chakra. It is unknown what the slug's plans are or why it wanted to seal itself within Rokubi, but with each coat can different traits and strengths appear.
