Rhoa Kwi were a type of sizable and terrifying predatory creature native to the world of Dathomir, frequently moving about in groups. These creatures were two-legged reptiles characterized by their substantial, boxy skulls. Small, round eyes were positioned on either side of their heads, and pointed, razor-like teeth protruded upwards from their bottom jaw. Their skin was a greenish-yellow color. If angered or threatened, they possessed the ability to project a venomous fluid. They represented a specific variation within the broader Kwi species.
