I'm currently writing a fanfic where the characters have powers based on their personalities. One of my characters in an energy manipulator. The Characteristic Power reflection page gave examples of people having powers based on the type of person they are: shy person gets invisibility, regretful person gets temporal rewind. I know that elemental manipulators often have powers associated with personality: Fire = hotheadedness and anger; ice = emotionally numb or distant; electricity = hyperactive, joyful.
But what personality fits a person who manipulates pure energy?
