I figured that might be an issue but not sure how much I could make her a hero while keeping a rather dark personality. I did have another idea in which she was a rather open hero. A name and obvious ability that she occasionally likes to show off, but her own motivation is still the same. A believer that good will prevail, but still someone who in the end not very far from being a villain? Either that or should I make her personality traits just a far more obvious hero or villain because I'm not sure what to how much I should change considering your criticism. 

Should her motives change? Her style and name be different or do you just want a person who's a hero to straight be a hero in ever respect same for a villain?
