Katherine has a feisty personality, similar to her mother and father. She is also stubborn and would rarely change her mind once it's made up, and would often sulk when things didn't go her way, and also has a hard time admitting when she is wrong. Despite this she is selfless and caring and never turns her back on people who need help. As such she was willing to sacrifice herself for a commoner when her planet was attacked. She would also go to lengths to correct something when something is wrong, breaking a few rules when necessary, and getting into trouble for it often, much like her parents and their gangs.
