This is a hypothetical fight between Taug (a.k.a. Pazuzu), a winged demon prince from the plane of the Inferno, and Sh'Fah, a ruby warrior of the crystalline Kx'Khrah race from the Crystal Plane. Though they've never fought, Sh'Fah was originally set to be summoned to the Prime Material Plane to guard Taug's crystalline prison and prevent any escape attempts the wayward demon might make.


Here are the descriptions I went by:

Sh’fah:
Having been summoned from the Crystal Plane, Sh'Fah, a Kx'Khrah warrior, is a large specimen of the Kx'Khrah warrior caste. It looks like a cross between a well-muscled man and a ruby scorpion, walking upright with arms ending in two great crystal pinchers and a tail that sweeps up over its head. The crystalline body is smooth and seems to be made out of ruby. Its eyes are multi-faceted and spins disconcertingly in many directions.
Sh'Fah, a Kx'Khrah warrior exudes an aura of overwhelming power.
He weighs about 500 pounds.

Taug:
Dressed in flowing red robes, Taug's wide mouth is stretched into a perpetual grin. Bat-like veined wings twitch about him and his features are somehow both delicately effeminate and fiendishly sharp. Large red almond eyes constantly rove and examine everything about him. His thin skeletal fingers end with vicious hooked talons. He is covered with a fine yellow fur and his long pointed ears are tuffed with black. He seems to be some perverse cross of a bat, a human and a cat.
Lord Taug has an air of extreme strength.
He weighs about 300 pounds.
