This is a simple reference sheet of Zoe Thompson, aka "Zeta", my OC from my Doom rewrite fanfic "Day of Wrath."
As an elite operative for the Penitent Church, working under direct command of the mysterious Blind Council, Zeta is tasked with executing missions across Earth and even occasionally the UAC's Mars Base. Though sometimes assassinations, easily accomplished through the thermal Mantis Blades concealed in her arms, Zeta is assigned for her unique abilities as a Succubus. All Succubi are gifted in telepathy, mind control, and illusions, employed in missions of infiltration, espionage, and sabotage. And with her extensive cybernetic augmentation, Zeta is as skilled with technology as she is with people. She can sneak in a place, take a target's disguise, cause the real person to enter a mindless killing frenzy while she hacks their confidential data, and walk out the front door, or sneak in and out that same place without anyone ever noticing.

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.
This second form is technically just a variation of the first, as she hasn't shapeshifted yet and has only discarded her UAC attire and deployed her concealed combat gear.
