Bear-sarks are described as tall and muscular. They have the bodies of men and the heads, claws, and feet of black bears. Their clothing hangs in rags abut their body and they wear thick bearskin belts around their waists. Sometimes they have ram horns and wear hooded cloaks.
For weapons they carry short-handled battle axes and black obsidian knives.
There is a brief fight that is ended when Tsagaglalal shows up and slays the bear-sarks.
