Kimberly "Kim" Crawford is a 15-year-old girl who is a confident martial artist and the only girl in the dojo. That doesn't mean she can't go head-to-head with any the boys in the dojo though. Kim's skills are equal to Jack's, the only other black belt in their dojo and she isn't afraid to use that to her advantage at times. She was a former member of the rival dojo, The Black Dragons, but joined the Bobby Wasabi Academy after finding out the Black Dragons were cheaters. Many people underestimate her because she's a girl. Kim also doesn't like being called just another pretty face. Kim has been known to lose her temper quickly, and she won't hesitate to threaten or attack a person, usually causing Jack to step in before things get ugly. In Hit The Road Jack, it is revealed that she has feelings for Jack, which she admitted it to Joan.
