Fiona was a determined fighter, eager to oppose evil since her capture at the hands of Robotnik. Somewhat prideful, she tends to hold grudges, such as against Rouge the Bat, who defeated her and the other members of Nic's gang in an illegal fighting tournament, and towards Sonic and Mighty the Armadillo for failing to save her when she was captured by Robotnik as a child. She has had a history of mild illegal activity, including robbery, hinting at her less than noble nature.
