Muu

無

Muu (無, Muu) served as the Second Tsuchikage (二代目土影, Nidaime Tsuchikage; literally meaning "Second Earth Shadow") of Iwagakure.
Muu can blend perfectly into his surroundings. His camouflage is so effective that he earned the title "Non-Person" (無人, Mujin), a name reflecting the appearance of having neither form nor chakra while the technique is active. Normal detection methods fail against him, leading Muu to regard anyone who can sense his presence as worthy of praise.
Muu is among the few individuals capable of wielding a kekkei touta, a highly advanced and potent variant of kekkei genkai. Specifically, he possesses Dust Release, which enables him to fuse fire, earth, and wind natures to reduce opponents to mere dust, destroying them down to the molecular level. When compared to fellow Dust Release user Oonoki, Muu's power is suggested to be on par; during their joint execution of the Dust Release: Detachment of the Primitive World Technique, the chaotic and disastrous result showed no clear victor in terms of strength. This may stem from the fact that Muu's power did not diminish after his death, a point later confirmed by Oonoki.
