Though Lekmet only speaks in goat sounds, his personality comes through largely in his mannerisms. He shows a deep level of care for his companions and mainly serves as an observer to Rhombulus' conflict with Glossaryck.
Lekmet mainly bears the appearance of an anthropomorphic goat. He has pale cream fur, yellow eyes with diamond-shaped pupils, four brown horns (two pointed straight upward, two curled on the sides of his head), a long gray beard, and large bat-like wings. He wears a long brownish-gray cloak.
- According to Star and Marco's Guide to Mastering Every Dimension, Lekmet was created by Glossaryck so that Mewmans would have an understanding of the impermanence of existence.
