Explanation: Your brain is highly evolved and has learned to communicate with others. This makes you able to control peoples thoughts since their brains hasn't evolved as much as yours and can't fight back. And that way you can make people do stuff without complaining. In good purposes it can be used to convince the "villian" to give up. But in bad purposes they can use it to gain anything, by for example convince people to give all their money to the mind controller.
The power fits you since you have the need to be in control and boss around. It's nothing personal, you just like to have everyone under your eye. That's because you don't know where you have everyone else and don't know if they are going to betray you and stay by your side. That can also lead to you being jealous. It's all to hide your insecurity. You can also be competitive and feel like you have to prove yourself. Sometimes you can also act immaturely, which can also be entertaining for your friends. You are also protective and don't like is someone trash-talks your friends.
Negative aspects: Your bossyness can get out of hand and your jealousy can scare people away. This is not intentional but can happen all the same.
