Mō-Mō

Mo-Mo is a three-eye ox that belongs to Totosai. He attacks using beams like Ah-Un. He also possesses the ability to fly and is one of the two yokai in the series that is shown to be a herbivore (the other being Ah-Un). His hide also seems to be somewhat resilient, as Totosai and the others seen taking shelter behind him when Inuyasha first uses the Kaze no Kizu against Sesshomaru.

Mo-Mo has three eyes that can see things far away even into the underworld. Totosai was able to show the battle between Inuyasha and Sesshoumaru by hitting Mo-Mo on the head with his hammer.
