*Fiona Fox (born 3221) is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She is a mobian fox. She is a casualty of Dr. Robotnik's conquest, who in the current day finds herself flip-flopping from group to group looking for a place to belong.

She was one of the many victims of Dr. Ivo Robotnik's rise to power, and as a child, she was left in prison, abandoned by Sonic the Hedgehog and other Freedom Fighters. As a result, she came to develop a personal vengeful grudge against them, with time developing the darker traits of her personality. Upon escaping, Fiona led a life of treasure hunting and other petty crimes, until, following Sonic's apparent death, she attempted to turn over a new leaf by joining the Knothole Freedom Fighters, and even began a relationship with Sonic following his return from space. With time, however, Fiona gravitated back towards her old ways, and ultimately decided she preferred the darker side of life. To this end, Fiona fell in love with Sonic's Moebius counterpart, Scourge the Hedgehog, becoming his girlfriend, and later Queen of Moebius itself following Scourge's takeover, and became a member of the Suppression Squad. However, following the other members of the Suppression Squad betraying both Scourge and Fiona, Scourge was being sent back to his home world, Fiona fled from Freedom HQ, though her loyalty to Scourge remained.

For her current design, Fiona looks far more different than she did before: she is taller and slenderer, has red hair and a yellow muzzle, and no longer has a lighter color of fur on her belly. Her hair is also longer, thicker and a bit more spiked. As with her previous design change, she still retains her yellow bow. Fiona also now wears a black belly top, black elbow-length fingerless gloves, a gray belted-skirt with a black buckled-belt, and black skinny pants that have gray padded shoes attached to them. During her time in Zone Jail, Fiona wore an orange, collared, button-down top tied just above her belly, and matching baggy, orange pants. She still sports the same black gloves, black shoes and the same yellow bow. When she and Scourge escaped, she wore his black, flamed, torn-up leather jacket and his sunglasses.

As a result of her capture at the hands of Robotnik. Fiona was 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. She is also extremely clever, and has an acute memory. However, she was clearly reluctant to talk about her past. It was later revealed that she chose to follow a darker path in life (likely due to her past) and developed a relationship with Scourge, preferring the "evil" version of Sonic to the virtuous real deal.*
