Emily

Summary
Emily is a girl who was kicked out of her house by her religious parents after her mutation manifested. Looking for a place to stay, she got indoctrinated into the Demon Lord's cult. As a mutant, she's automatically a higher ranking member, vs the non-mutant recruits who haven't earned the right to mutate yet.

Even before she mutated, she's had a port-wine stain on her face that has earned her lots of negative attention.

Her breath has hypnotic / hallucinogenic properties. Breathing it in in close range can put you in a trance-like state. Simply being near her for extended periods of time can make you somewhat intoxicated with slurred speech. If she gives a command to someone who is affected by her breath, they will be compelled to obey it. Unlike hypnotic states where people cannot remember being under the effects of it, people affected by her breath do not suffer memory loss. Instead, the drug-like effects cause delusions and hallucinations that justify to the victim the actions they will take. I.E, if she commands one person to attack their friend, the person may have repressed feelings manifest, or hallucinate their friend as being an enemy / monster. This makes fighting its effects hard.

Trivia

 * She can fly, but she's slower with less endurance compared to Birdy. Her horns are also softer than Maria's; easier to break and scratch, but they heal easier.
 * Big fan of comic books, on par with Kevin, but does not like the MCU.
 * Has a huge appetite, constantly craves high-protein foods. Kinda naturally muscular with a high metabolism, despite rarely working out. People joke she has the appetite of a teenage boy.
 * She uploads videos of herself eating ridiculously large portions of food to youtube. Makes money to support herself through ad revenue and a patreon. Supporters get early access and can make requests. She's been doing this since before she mutated, but now that she's an adult whose been kicked out of the house, its even more important she does.
 * Her commands are less likely to succeed if shouted, or spoken quickly. She must enunciate and keep her voice soft and slow.
 * It's possible for others to take advantage of her breath. Giving a command to someone as Emily breathes into their face has the same effect as if Emily did so herself. Whether its Emily or someone else who does so, giving a command to someone long after Emily blew into their face has no effect, unless a fresh dose of hallucinogen is applied.
 * Her breath has a catnip like effect on cats instead. Has no effect on dogs. Also has a risk of suffocating borrowers like Chief.
