Fiona Fox

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. Tails was Fiona's comrade from when she was a Freedom Fighter. Tails had a huge crush on Fiona ever since he met a younger, robotic version of her during one of his solo adventures. While being touched by his attention and care, Fiona saw Tails the way she saw the other Freedom Fighters. She went on to tell him about it when Tails discovered her relationship with Sonic. This left Tails heartbroken. Regardless, they remained on good terms, as Fiona would still pet his head with affection. Things changed, however, when Fiona met Scourge, whom she fell in love with and started hanging out with in secret. When Tails learned about it from Sleuth, he did not want to tell Sonic out of fear of losing Fiona forever. When he later pleaded with Fiona not to go with Scourge, Fiona cruelly slapped him. In order to reform the Destructix, Fiona went to Sonic and Tails for help. While she failed to convince Sonic, she turned to Tails until Sally punched her. Sonic was Fiona's first boyfriend. She saw him save Mighty and Ray while she was left behind. This made her hold a grudge against Sonic until she joined the Freedom Fighters and got to know him better. They eventually started hanging out some time after Sonic and Sally broke up with each other. They proceeded to have a passionate relationship until Scourge showed up and assumed Sonic's identity for a while. This worked with Fiona as she secretly engaged in a new relationship with Scourge after his real identity got revealed. While she insisted that everything was a lie, Sonic started to notice that she did not look at him as before and doubted her motives. Though he learned the truth, he invited Fiona to explain herself. Eventually, Fiona told him that she did not feel the same attraction in him as Scourge, and thus broke up with him. Scourge is Fiona's current boyfriend. They met during the time Scourge posed as Sonic on Mobius. During this time, Fiona immediately felt a stronger attraction to him than Sonic. She thus engaged in a secret relationship with him and complied to his schemes. When Sleuth told about this to Tails, Fiona insisted that it was a lie and kept hanging out with Sonic. Fiona later told Sonic that she did not feel the same attraction in him because he was weak and nice. As such, Fiona and Scourge left for Moebius to start their empire. Since the beginning, Amy and Fiona did not have the best relationship. At Sonic's surprise birthday party, she watched Fiona hugging Sonic with bitter jealousy. No matter her jealousy, however, she and Fiona were comrades as part of the Freedom Fighters and fought to protect the Kingdom of Knothole. However, Amy would attack Fiona when she learned about her unfaithfulness, and tried reminding Fiona about Sonic's feelings. While Fiona told her that Sonic would not believe her. Amy later came back to punish Fiona for hurting him and forcing her to leave.

Appearance: 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.
