So my two MC's are Super Villains in a comic book like world. He's like a demon (he used to be human it's a very long story) and she's like his servant and his biggest well she's like the Mercy to his Lex Luthor. The way they met was she was young and the victim a human trafficking and he started whispering in her ear. He basically built her up by talking to her telepathically telling her how to manipulate and kill her captors. He would often say "I can open up the door but you must choose walk through it." that's kind of how he helped her. She was abducted at age 13 and he started talking to her when she was 15 and basically she's been serving him for a while. She's very devoted to him and is a true believer in his vision and his vision is world under his rule. He desires to create a world free of "evil" and he's a total means justifies the ends type. She is an avid believer of the utopia he wants to create and she shares his vision because for her if he creates the world he wants to create what happened to her will never happen to anyone else. My problem is they aren't equals and neither has a problem with it. He sees her as a worthy servant and she well she's drinking his cool aid. The idea is that she sort of wakes up what little humanity is left in him. Now this is my problem I'm not sure if my Female MC will be as interesting because she's his groupie. This is there relationship she's willing to give up anything for him and he's willing to give up anything for her which surprisingly upsets her. She sees herself as disposable he doesn't see her as disposable at the same time he says things like "You belong to me no one else can touch you no one else can have." he says this to as strange as this may sound comfort her when she has a ptsd episode or nightmare about something that happened to her. Again though I'm not even sure how to develop their relationship because they are a pretty rock solid team.
