Laustra

Laustra is the central antagonist of the book Hell's Embrace by Marc McGowan.

appearance
Laustra is an ancient demon and is approximately 3,120 years old. In her human form she appears as a tall, muscular, lovely, young woman with flowing red hair, pale skin, and sparkling green eyes. It should be noted that this human appearance is merely a disguise, and it is actually quite physically taxing for her to maintain. As such, the more human she appears, the weaker she is at that time. Laustra is gifted with monstrous physical strength due in part to the fact that her bone and muscle density is roughly 3X that of an ordinary person. Humans who encounter her often remark that she is much heavier than she looks.

In her demon form Laustra is at her most powerful. Her flawless pale skin becomes dark, thick and scaly. She grows a long tail with a sharp point on the end, and large wings similar to those of a bat. Her face still remains remarkably pretty, but she sprouts two long horns that extend out and curve back over her head. Her clawed fingertips are capable of cutting through steel.

powers and abilities
Being well over 3,000-year-old, Laustra has become incredibly powerful. In her weakest human form, she has vast physical strength and durability, and is capable of engaging other supernatural creatures in combat with relative ease. If ever weakened, she uses her beauty as a trap for unsuspecting people and then consumes their life energy as a source of sustenance. In her younger days one human virgin could fuel her for weeks, but as she has grown older, she requires more feedings to keep her going.

Laustra can "charm" humans with an evil spirit and compel them to do her bidding. In desperate times she can also mate with compatible human males to produce demonic offspring. The period of gestation is roughly 8 hours.

In her demonic form Laustra gains even more strength and speed as well as the power of flight. She can also summon green hellfire from within her body and spit it out of her mouth like a flame thrower. In desperate situations, she can also emit the fire from the pores in her body. In her demon form Laustra is incredibly resilient and is able to withstand physical blows from other powerful supernatural creatures without much damage as well as resisting large amounts of electricity that would have ultimately killed a normal human of the same height and weight.
