Based on concept art, Mogu bears resemblance to a dragon, hinting that it may be related to Ghidorah. Additionally, Mogu has something spiky on its forehead, at least one claw, a pair of wings, and a sharp, forked tail.
Not much is known about Mogu except that it can fly and fire some type of projectile attack from its mouth. It also appears to have a sharp tail, that may be used as a weapon, as well as razor sharp claws, and a crest of spikes.
