Mō-Mō

was a three-eyed cow yōkai that belonged to Tōtōsai and acts as the forging demon's traveling companion. He was one of the two yōkai in the series that was shown to be an herbivore (the other being A-Un).

Powers and Abilities
Flight: Mo-Mo possesses the ability to fly by projecting clouds under his hooves to sail through the air.

Teleportation: He also has the power to teleport almost anywhere else through a lightning bolt though he seems to favor flying more.

Enhanced Durability and Defense: He has physical resiliency and defenses higher than what his appearance would suggest. This is displayed in the fact that he's capable of living in the molten environment of the volcano Totosai's forge is located in without any hinderances while lesser demons like Jaken are severely burned just by entering it. His hide itself is also more sturdy than expected as Totosai and the others took shelter behind him when Inuyasha first used the Kaze no Kizu against Sesshomaru.

Enhanced Vision: His three eyes are capable of seeing things far away even into other dimensions.
 * Vision Projection: Totosai was able to show the final battle between Inuyasha and Sesshomaru over Tessaiga by hitting Mo-Mo on the head with his hammer, causing the fight to be displayed in real time from Mo-Mo's eyes like a film projector
