Locust Demon

Standing before you is a creature of horrific appearance. It appears to be a horse, though it is obviously far from being one. Greenish-black scales cover this monstrosity. On its back sprouts massive insect-like wings. Perhaps the most horrifying feature on its body is its face. Its face is not that of a fiendish horse, but that of a fiendish human, which rests upon a long horse-like neck. Two black horns curve up above on its forehead, while a golden crown rests on top of its head. Its eyes glow a baleful red.
