Male demons who have the ability to shapeshift into any human or animal form, dark energy as their elemental energy, has the ability to genderbend into succubus as succubus to Incubus. Like Succubus their true form looks human with minor demonic traits be it horns, tail, both, some normal eyes, some serpentine eyes. Ones with “low” energy system require sexual energy or some form of energy to live to the best of their ability and those with “high” energy systems do not and only do so through means of pleasure.
