She is a roguish speedster with an arrogant, cocky, and hot-tempered disposition, taking great pride in her prowess and bragging at any given opportunity. She is also fearless and bold, rarely showing any form of worry or concern, even in situations that are troublesome or possibly beyond her capabilities. When push comes to shove, however, she tends to give in to anger, causing her to become a more volatile force.
