Personality: sultry, determined, persistent, superior
Pros: She can change her body shape at will to an extent. (Natural breast size: 32C) is strengthened by sex, can hypnotize certain people (only works for sex), can raise and command the dead, is skilled at swordplay, can conjure her weapons and simple things out of midair, pyrokinesis.
Cons: thinks she's better than most people, will die unless she has sex within 24 hours (this includes giving oral, but she can't steal a soul using only oral) or steals enough life-force with her katana (Only if she isn't in Hell), her reflection always shows her true form no matter what she currently looks like, any injuries she has will carry over to any other form she takes (if she gets hurt on a species specific body part she has to stay as that species until it heals, though she can still alter her appearance), if her tail is injured she can't alter her body at all until it heals, obsessed with her beauty.
Weapons: demonic katana (steals the life-force of whatever it cuts), demonic throwing knives (Paralyze whomever they cut.)
History: Born as a succubus, Cassandra grew up doing as Satan ordered, sending souls to Hell for him, day after day. Knowing that she grew stronger with each person she slept with, Cassandra began to question her loyalty to Satan, as she'd never seen him do anything aside from bark orders at others. Thinking he was all bark and no bite, Cassandra began to spend her spare time practicing her combat skills and eventually challenged Satan for control of Hell. Easily defeating her, Satan decided to spare her life and instead banished her from Hell until she could send him 1,000,000 souls.
