Mō-Mō

is a three-eyed cow yōkai that belongs to Tōtōsai. He possesses the ability to fly and teleport via lightning. He is one of the two yōkai in the series that is shown to be an herbivore (the other being A-Un). His hide also seems to be somewhat resilient, as Tōtōsai and the others take shelter behind him when Inuyasha first uses the Kaze no Kizu against Sesshōmaru.

Mō-Mō's three eyes can see things far away, even into other dimensions. Tōtōsai was able to show the final battle between Inuyasha and Sesshōmaru by hitting Mō-Mō on the head with his hammer, causing images to be displayed from Mō-Mō's eyes like a film projector.
