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 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, and as a result held a 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 Anti-Mobius 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.


At first, Fiona had brown fur and brown hair that was always seen with a yellow bow perched on it. She also used to wear yellow boots with a belt that had a dagger in its holster. Fiona's design then changed to have brown hair that was longer than the first design for her hair but retained her yellow bow. She also stopped wearing the belt and dagger and yellow boots and changed to wear a yellow zip-up leotard that had a white stripe in the middle, a grey neck-cuff, and arm and leg holes. With this leotard also came long, yellow sneakers with grey cuffs that matched the neck-cuff. Fiona's sneakers also had a white design at the toes. This outfit last appeared in #172.

As to her current design, Fiona looks far more different than she had before: she is taller and more slender, 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 grey belted-skirt with a black buckled-belt, and black skinny pants that have grey 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 child, Fiona was one of many mobians that was captured to serve in Dr. Ivo Robotnik's mining camps. Not long after arriving, she and her fellow inmates Mighty and Ray caused an uprising that was quickly quelled by the robots guarding the camp. While Mighty and Ray were locked up in isolation, Fiona was taken away for another purpose. Not long after, a young Sonic the Hedgehog (who was investigating the camp as one of his early Freedom Fighting missions) arrived and freed both Mighty and Ray.

The three then went out in an attempt to rescue Fiona but ultimately failed to free her. Due to the mysterious disappearance of Ray, Mighty went berserk and began trashing the facility, forcing Robotnik to abandon it. Fiona was brought away by Robotnik when he fled and relocated to a new facility built the exact same as the previous one. While there, she was used as the basis for one of Robotnik's many robotic replicas designed to infiltrate the Freedom Fighters. Soon after creating the robotic duplicate, Robotnik left the real Fiona to die in a prison cell.

Escape and Life as a Treasure Hunter

After a long period of imprisonment, Fiona realized that, like at the lab, no one would rescue her, and thus she became determined to do so herself. Through long, grueling attempts she managed to dig an escape tunnel from her cell, eventually reaching freedom outside. The first person she encountered was Nic the Weasel, a bounty hunter on a treasure hunting mission.

Fiona and Nic both became involved in treasure hunting and thievery, which soon resulted in a rivalry with Rouge the Bat. The two later were joined by Bean and Bark, all of whom suffered defeat in underground fighting tournaments thanks to Rouge. Eventually she and Nic returned to the mining camp to see if they could find anymore Power Gems; unfortunately, the lab door was locked and neither could open it.

Fiona remained somewhat embittered by her past encounter with Sonic and Mighty. This became apparent after Nic decided to gain Mighty's assistance to gain access to the laboratory, as Fiona explained how she felt abandoned by the two. While exploring the camp, they discovered several unused robotic replicas of the Freedom Fighters. Eventually they reached the door, and Mighty forced it open. Inside they discovered a Power Gem - as well as Ray, who had apparently been stuck in a form of suspended animation by the gem. Despite herself, Nic destroyed the gem in order to free Ray.

Freedom Fighter

Sometime after Sonic's apparent death due to the Quantum Dial, Fiona joined the Freedom Fighters. She acted in a general capacity, showing both computer and medical skills. Upon Sonic's return from space, Fiona accompanied the Freedom Fighter task force sent to Old Megaopolis to prevent Eggman from launching nuclear missiles at both Station Square and Knothole. While on board the FFS-M2, Fiona asked Rotor if they should all have space suits, as the ship flew to Mobius's outer atmosphere. Later, she provided medical attention to Sonic, who'd been wounded by Eggman's robotic "daughter" Mecha. Fiona was also the one to explain to Sonic that Antoine and Bunnie had broken up during his absence in space.

Fiona accompanied the Freedom Fighters during their mission to an ancient laboratory to discover the cause of severe seismic activities. She briefly left the group in an attempt to hot-wire the lab's systems, though due to its self-defenses she was unable to. At one point, Fiona, Rotor and Bunnie had all been electrocuted by the lab's self-defense systems, but were saved in time by Tommy Turtle. After, Fiona discovered a heavily powered rifle, but was informed by Rotor the Freedom Fighters never resorted to gun-like weapons.

Fiona accompanied the Freedom Fighters to the Nanite City to rescue Bunnie, and was wary of working with Snively to prevent the nanites from spreading. During a period of rest, Fiona explained her long-held resentment towards Sonic due to him seemingly abandoning her in the prison camp, and that after witnessing his selfless efforts battling the Quantum Dial, developed a sense respect for him, and realized he didn't deliberately leave her behind all those years ago. Following this, she helped the Freedom Fighters to defend Mina Mongoose from a series of Bombs attacking her concert, and she was present at the Brain Trust's examination of the discovered Nanites.

Following this, Fiona and Sonic began a relationship. The two were discovered secretly flirting near a bush by Tails, and after Fiona explained she felt no romantic connections to him like she did Sonic, Tails left angrily. The same day, Sonic managed to prevent Anti Antoine from killing Prince Elias, and after sending him back to Anti Mobius, Fiona and Sonic began officially dating.

When Bean and Bark attacked Freedom HQ and it was obvious that they knew Fiona, shades of her past were revealed and, despite her assistance in stopping the attack, seeds of doubt were planted among the minds of the Freedom Fighters. When the Chaotix needed info on Rouge, Fiona reluctantly explained her past encounters with the bat, as well as her past involvements in crime. Sonic continued to support Fiona, but eventually it became more and more obvious that something was going on, as Fiona developed a tendency to disappear and skip missions.



During the time when Rouge was in Knothole, Sleuth "Doggy" Dawg appeared, looking for her on behalf of Dr. Finitevus. He held Tails and Fiona hostage while Sonic battled Scourge the Hedgehog. During it all, Fiona called Sleuth a traitor; he replied that she was one herself. Scourge also taunted Sonic for hanging out with "his" girlfriend. A compromise was reached; Sleuth would leave Rouge alone if the Warp Ring she had stolen was returned. Sonic returned the ring; however, it became apparent that between Sleuth and Fiona, Tails had learned a horrible secret. Because of his conflicted feelings between Fiona and Sonic, he did not tell the latter what he had learned.

Eventually his guilt caught up with him and he confided in Amy Rose; Fiona had been cheating on Sonic with Scourge, Sonic's evil self from an alternate dimension, over the course of their entire relationship. Amy, enraged that anyone would betray Sonic's heart, sought out and attacked Fiona. While dodging blows, Fiona feigned confusion, though briefly slipped in a smug grin and told Amy no one would believe her anyway. To the surprise of both, Sonic casually butted in and told Fiona he wanted to talk. As they walked, he confronted her about lying and her disappearances. She became indignant, but all was soon explained when Scourge showed up; Fiona was in love with the evil hedgehog. When Evil Sonic had infiltrated Knothole Village, he had hit on several of the girls there, including Fiona, before being ousted. Fiona, having realized that she'd fallen for a fake, tried to find the same attraction in the real Sonic and thus began to date him. Unfortunately, she found him too "vanilla" for her tastes; she preferred Scourge's dark side and began to sneak off with him.

Finally exposed, she decided she no longer cared to keep up the charade or act as a Freedom Fighter. Tails suddenly intervened, begging her not to do so and appealing to her good nature. She gently told him that despite his intellect, he didn't realize one thing - "you can't count on anybody." She then slapped him across the face. Sonic, enraged at her cruelty, protested, and Fiona cited his abandonment of her, back in the mining camp, as an example. Shortly after she and Scourge then escaped via Warp Ring.

Working for Dr. Finitevus

Fiona reappeared not too long afterwards, sporting a new look and taking up a role as one of Dr. Finitevus' agents. Together with Scourge, she came bearing bad news: not only had the Dingo Regime decided to attack Echidnaopolis, but the warring factions of the Dark Legion under Lien-Da and Remington had put aside their conflict to stop Finitevus' plans to resurrect Enerjak, the arch-nemesis of Knuckles the Echidna. While Finitevus left to complete his work, Scourge sat down to relax while Fiona bristled at the situation, clearly disliking the albino Echidna as much as Rouge had in her brief time in the doctor's service. She didn't have long to complain, however, before the new Enerjak made his awe-inspiring debut right in front of her and Scourge. Fiona played a part in the recreation of this awesome figure, as she and Scourge had worked with the other Destructix to knock out Knuckles the Echidna when he returned to Angel Island, and delivered him to Dr. Finitevus whose plans finally came together to make a new Enerjak out of the original's greatest foe.

While Enerjak started his campaign against the elements of Mobius he had decided to eliminate, Fiona and the other Destructix were sent by Dr. Finitevus to guard a weapon that had been built by the Brotherhood of Guardians as a precaution against Enerjak's return. She and her allies would soon be forced to defend it from Knuckles' father Locke, Sonic, and Julie-Su. Though the battle was intense-not to mention an opportunity for Fiona to point out that Sonic and his allies had often beaten their foes either because of superior numbers or because their enemies had been ordered to lose-it ended quite abruptly when Sonic destroyed the weapon and the Destructix left, not sure of what to do next. The battle between Super Sonic and Enerjak decided for them, and Fiona left Mobius in Scourge's company as the green Hedgehog set out to find his true self, while the Destructix fled through a different Warp Ring.

The Suppression Squad

The Warp Ring brought the couple to Moebius where Scourge invaded his home world, determined to re-make and set everything on his world apart from Mobius Prime. Scourge made Fiona his queen and second in command of the Suppression Squad after conquering the planet. Fiona did her duties well, only being contested by Princess Alicia, who was the original heir to the throne before Scourge's takeover. Under Fiona's supervision, the Squad repaired a pair of stolen Globe Posts and used them to launch a successful invasion of Freedom HQ.

When Sonic returned during the Suppression Squad and Freedom Fighter ambush, he was blocked by Fiona. At the time, she claimed she was betrayed time after time, and couldn't rely or trust anyone. Sonic then pointed out that she was breaking her own rule for Scourge, and implied that Fiona might actually care for Scourge, making her cry. Furious, she yelled that it wasn't "like that", but Sonic simply told her "keep telling yourself that".

Following Scourge being tossed back to Moebius by the Suppression Squad, Fiona fled from the scene. Scourge would later question Patch if she was with them when they arrived back in Moebius, stating that she was smarter than the Suppression Squad for getting out "when the going was good".

Rejoining the Destructix

Fiona later appeared when Sonic and Tails waited for Monkey Khan and Sally to finish talking to Lord Yagyu. She said that she fled "when the going was good" and found the Destructix. She was wondering why Drago and Sleuth left but learned that they joined Eggman and Fiona then became leader of the Destructix, who came to the Dragon Kingdom to get Lightning Lynx (who left when he was called back from exile by Conquering Storm) to join the Destructix. After a "quick game of tag", Fiona and the remaining Destructix asked Sonic, Tails, Monkey Khan, and Sally to help them get Lightning Lynx back. To ensure Tails would join, she started playing on the young fox's emotions to which Sally punched her in the stomach. Nevertheless, they joined and after Sonic beat Lightning Lynx in a fight, he was exiled again and rejoined the Destructix, as well as the Raiju Clan breaking their ties to the Iron Dominion.

Journey to the East

Currently with her personal ideas, Fiona decided to gather some of the Destructix at the Bottom of the Barrel Bar 'n' Grill, but only found the remains in the form of Sergeant Simian, Predator Hawk and Flying Frog. Drago Wolf had left the group to rejoin the Eggman Empire, while Sleuth handed over leadership to Fiona so as to preserve his own interests. The trio eventually agreed to serve her, but only if she helped them recover their much more valued comrade, Lightning Lynx, who was residing in the Dragon Kingdom.

The four then set out to the Dragon Kingdom, where Fiona confronted Sonic and Tails within a bamboo forest as part of a trap, vaguely mentioning she'd been busy since they last met. A chase through the thicket led the duo to the remaining members of the Destructix. Once Sonic and Tails were subdued, she told them they had something to "discuss"- namely an alliance that would meet with her own ends. However, she didn't get a chance to until she ordered her muscle to stop fighting the Freedom Fighters after Sally Acorn and Monkey Khan showed up. After a brief engagement—in which Fiona and Sally clashed heatedly and she was punched in the gut after toying with Tails—they reached an agreement, and she revealed her plan. Reluctantly, the Freedom Fighters joined them, as they were also set to clash with the Raiju Clan: the Freedom Fighters looking to break ties between the Clan and the Iron Dominion, and the Destructix looking to convince Lightning to leave the comrades he had rejoined. The unlikely team soon stormed the Iron Fortress, and Fiona and Sally were flown over the walls to unlock part of the gate mechanism. After they found the Bride of Conquering Storm, Sonic and Lightning battled to determine the outcome of their journeys; a defeated Lightning left with the Destructix. Eager to win his loyalty, Fiona promised that her plans would see everyone who had done them wrong repaid.

Jail Breaking

In an attempt to free Scourge from the Zone Jail in the No Zone, Fiona gathered the Destructix and purposely vandalized and fought against the Zone Cops in the Cosmic Interstate. As of the result, they allowed themselves to get captured and Fiona eventually met up with Scourge, who couldn't use his abilities due to a Control Collar around his neck. Scourge seemed frustrated at them and was reluctant to use their assistance, but Fiona persuaded Scourge to convince the Destructix that they could have revenge against their former enemies/allies.

Upon succeeding in this plan, Fiona and the rest of the Zone Jail prisoners caused a jail break, but only Scourge, the rest of the Destructix, and her managed to escape through a Warp Ring. They now plan to aid Doctor Finitevus in a plan of some kind in Moebius.


Fiona is 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 a history of mild illegal activity, including robbery. She is also extremely clever, and has an acute memory. However, she is clearly reluctant to talk about her past. It was later revealed that she chooses to follow a darker path in life (likely due to her past) and develops a relationship with Scourge, preferring the "evil" version of Sonic to the virtuous real deal. She is also great at gymnastics for example once performing a back-flip off a bamboo tree.


When the real Fiona joined the Freedom Fighters, Tails became emotionally troubled, since he still has feelings for the Fiona robot he had met. This problem came to a head when Tails saw Fiona and Sonic apparently embracing, leaving Tails feeling betrayed and even more confused. Fiona tried to explain to Tails that the robot he had fallen in love with had been based on her when she was much younger. Although she did like Tails as a friend, she was fifteen whereas he was only eleven, and she did not share his romantic attachment.

Tails' resulting anger was later revealed to be unfounded, as Fiona had never cared for Sonic either. Her feelings were for Scourge the Hedgehog, whom she apparently established a relationship with during his impersonation of Sonic. Upon learning the truth of his identity, she tried to find the same feelings for the real Sonic, but the differences between the two were too great and Fiona remained in love with Scourge. For his part, Scourge was attracted to Fiona because unlike the women he had formed relationships with in his own dimension, who were villainous from the start, she chose to follow the path of a criminal despite being inherently good. As a further blow to Tails, Fiona Fox insulted him openly and slapped him across the face upon her departure.


  • Through a combination of story and artist inconsistency, Fiona's fur pattern are depicted to change drastically from issue to issue and artist to artist. Early iterations had her eyelids and belly colored in cream or light orange before both being unexpectedly changed to red. Her fur color pattern was also somewhat reverted again during the Scourge Lockdown story arc, with only her eyelid color being changed to her original light-orange by the same artists with no explanation.
  • Fiona's relationship with Scourge the Hedgehog can be seen as the evil equivalent to Sonic and Sally's relationship.
  • Fiona Fox is one of the few characters to ever weaken Sonic and Tails' friendship.
  • Fiona's eyes are often mis-colored to be grey.
  • Fiona's current hair-style appears somewhat similar Sally Acorn's, only a bit longer.
  • Fiona said that the robot was based off of her at Tails' age. Tails is 10, thus she was 10 when she was captured.
  • Fiona has mentioned her family two times within the series.
  • It is often been misunderstood by fans of the actual ownership of Fiona due to the lawsuit case between Archie Comics and former writer Ken Penders with many believing Fiona belonging to Penders. Although Penders helped recreate Fiona but the initial character, Auto-Fiona was originally created by Michael Gallagher and Penders has stated that he does not want to claim a character he did not create.[2]
