Cambion

A cambion is the offspring of a fiend (usually a succubus or incubus) and a humanoid (usually a human). Cambions inherit aspects of both parents, but their horns, leathery wings, and sinewy tails are hallmarks of their otherworldly parentage. Born to Be Bad. Cambions grow into ruthless adults whose wickedness and perversion horrifies even the most devoted mortal parent. Even as a youth, a cambion identifies its rightful place as an overlord of mortals. It might orchestrate uprisings in towns and cities, gathering gangs of humanoids and lesser devils to serve it.
Pawns of the Mighty. A cambion forced to serve its fiendish parent does so out of admiration and dread, but also with the expectation that it will one day rise to a place of prominence. Cambions raised in the Nine Hells serve as soldiers, envoys, and personal attendants to greater devils. In the Abyss, a cambion carries only as much authority as it can muster through sheer strength and force of will.
Spawn of Graz’zt. The demon lord Graz’zt is fond of procreating with humanoids who have made pacts with fiends, and he has sired many cambions who help him sow chaos across the multiverse. These cambions are characterized by charcoal-black skin, cloven hooves, six-fingered hands, and unearthly beauty.
