Power is childish, greedy, and almost entirely self-motivated. She tends to fight as if she has something to gain and is certain of her victory, and has no problems with running away from a fight where she is outmatched. She feels the need to boast her superiority over her fellow Devil Hunters due to her status as a Fiend. She has no loyalty to humans or Devils, openly admitting that she will join whichever is the winning side. Power also enjoys the thrill of a fight and enjoys showing off.
