Half-fiend

"This winged humanoid has claws, fangs, and short horns. Its eyes glow red, and it reeks of brimstone"

Description
A fiend's magical nature allows it to breed with virtually any creature. Spawned deep in the dark, nether planes, these fiendish offspring are abominations that plague mortal creatures Demons and devils bring their prodigy along to the Material Plane and loose them upon the world. Sometimes, however, fiends force themselves on mortal creatures to create evil half breeds. The more depraved creatures are sometimes even willing to participate. Although half-fiend offspring are usually destroyed at birth, some survive to become grotesque mockeries of their mortal parents. All to rarely, though, one learns from and takes on characteristics of its non-fiendish parents, turning from its evil heritage. No matter its form, a half-fiend is always hideous to behold, having dark scales, horns, glowing red eyes, bat wings, a fetid odor, or some other obvious sign it is tainted with evil. Never truly fitting into any mortal society, half-fiends are usually loners. On the lower planes, they are mistreated and derided because of their impure nature. Among non-fiends, they are outcasts, hated corrupters of the natural order. Humanoid half-fiends are sometimes called cambions. They often serve more powerful fiends or lead evil forces on the material plane.

Combat
Half-fiends are usually Clerics of deities such as Erythnul, Gruumsh, Hextor, Nerull, and Vecna. Half-fiends attack with with aggressiveness and battle lust, using their ability to fly to best advantge by casting spells from the air. They enjoy torturing any enemies unfortunate enough to fall into their hands.
