Tleyzu come in a run of all colors of the 'Tween from vermillion to violet, all of them have a third eye in the center of their foreheads of bilious yellow with a red vertical slit that can cause those looking upon it or that they look upon to fall into a drooling stupor, and disproportionately wide grimacing mouths filled with teeth.

All Tleyzu seem to have a weakness towards heat and fire, though they have no fear of it. All Tleyzu can fly via will alone, though some are faster than others.

Most Tleyzu are not very intelligent, having intelligence equivalent to a hyena or wolf and vocabularies of zero to a hundred words. However, some rare Tleyzu are frighteningly and malevolently intelligent.

Other than that nothing can be said to be universally true about the Tleyzu as they take many forms and each one is individualistic.
