This is a simple reference sheet of Zoe Thompson, aka "Zeta", my OC from my Doom rewrite fanfic "Day of Wrath."
Zeta is almost universally considered to be an extremely attractive person, but that beauty is only skin-deep. She is in actuality a Succubus, a horrific and monstrous human-demon hybrid.
Far from the misconceptions popularized since ancient history, Succubi are cold, psychopathic, and remorseless predators, just as likely to bind countless men and women to their service as they are to slaughter them and consume their life force. Besides their potent psychic skills and proficiency at stealth, Succubi are also exceptional spellcasters, able to weave dark and arcane magics for devastating battlefield purposes.
Despite her relatively young age, evident by her still simplistic horns, Zeta has received extraordinary abilities from her extensive cybernetic augmentation by the UAC and Penitent Church, and the true reach of her power and full potential is still unknown.
She is certainly a formidable opponent to any of the UAC's and Penitent Church's enemies, including ARC, the Fortress of Doom, and perhaps even the Doom Slayer himself.

As a Succubus, and the first cyberized one, Zeta has the innate ability to shapeshift between an illusory human form and her true demonic form.
Pictured here is her third and final demonic form.
