Her most significant asset, however, has proven to be her extensive martial arts ability, as she has been practicing aikido since she was about four years old and has practiced martial arts in general every day since she was seventeen. While she does not consider herself a truly advanced student, she has studied Aikido, Wing Chun, Jujitsu, Kali, Savate, Krav Maga, Taekwondo, Judo, Boxing, and Shaolin Kung Fu. She can thrash all of the cops on the force, beat the snot out of Harry with little effort, and throw around people and beings much bigger and stronger than she is, in more than one case having brought Hendricks to his knees with simple wrist or finger locks. She is also Harry's instructor in stick fighting combat. She keeps herself in excellent physical condition via running, working out and regular martial arts bouts. So far, the only people in the series who are more skilled infighters than Murphy are several hundred years older than she is: the Hellhound, Nicodemus Archleone, and the Einheriar working for Marcone.
