Alright, I'm new so go easy on me.
Here's mine.
1. My primary power would be emotional manipulation. It's not like soothing or rioting in Mistborn where you influence emotions. I would dominate the emotions of my targets and make them do my every bidding.
Secondary power would be aura vision so that I could feel people's emotion and manipulate accordingly. This also doubles as a sort of X-Ray vision as when I activate aura vision the only thing I can see would be auras so I can look through things that do not contain aura, like walls. The auras would be like flames surrounding a person and they change color and intensity when the emotions and the intensity of an emotion changes.
Third power would be a simple danger sense. I get a small headache when danger would come in a few minutes. But besides that, I don't know anything else about the danger.
2. My weakness would be that anyone I have a very strong emotional connection (ie love) can overcome my control if they wanted to. This is why I would remain distant to most people in fear of them resisting my powers. Another weak point is that when in aura vision, the only thing I can see is auras, so a person might be able to use inanimate objects to kill me.
3. Alter ego would be The Charismatic (egotistic, I know) because people will listen to everything I say if I want them to.
4. Dressed inconspicuously in a suit and tie so that I could blend in with the populace and get close to those I need to control.
5. I steal what is most precious from people for fun. Their money, their cars, their pets, their children. Maybe even convince a few city rulers to commit suicide.
