Mizunoto

Mizunoto is a tall shinobi, with black hair tied in an elaborate top-knot. He wears a typical Anbu cloak. His mask is unusual in that it has two colours in it, with dark teal, dot-shaped eyebrows, and a red, sharp-toothed mouth.

In the anime, to prevent Hiruzen from being reinstated as Hokage, Danzō gave Mizunoto and nine other Root members a mission to assassinate him. Disguised as a foreign shinobi, he fought the Anbu accompanying his target, who turned out to be a disguised Kakashi, resulting in the mission's failure.
