Fox was once a member of the Pack and is now the wife of David Xanatos. She was born as Janine Renard, although she has since had her name legally changed to "Fox".
Born in 1966, Fox is the daughter of Halcyon and Anastasia Renard.  Unlike her father, Fox had no interest in strong moral principles such as integrity and responsibility, preferring a life of excitement and scheming. When she was twenty-five years old, her parents divorced. This event, and the marital problems that proceeded it, greatly affected Fox's views on love and relationships. 
She met David Xanatos early on and fell in love with him; later on, she joined the Pack when Xanatos set it up, becoming its leader. (She was also, so far as we can tell, the only member of that group who knew that Xanatos was behind it).
When the Pack first learned about the gargoyles and decided to hunt them, Fox met with Lexington and persuaded him to bring Goliath to them. She and the rest of the Pack then attacked the gargoyles, but were finally bested after a long and fierce battle. In an act of utter desperation, Fox took a swimsuit model hostage during the final confrontation, which quickly resulted in her and Wolf being arrested and sent to prison on Rikers Island. ("The Thrill of the Hunt")
In prison, Fox remained in contact with Xanatos, and helped him set up the scheme to lure Derek Maza into his service, by employing Jackal and Hyena to carry out an attempted assassination of Xanatos. Not long afterwards, Xanatos sent Coyote 1.0 and Dingo to break the rest of the Pack out of prison, but Fox refused to leave, insisting on serving out her sentence, and even saved a guard from Hyena. The parole board for the prison granted her an early parole in view of her actions; in fact, Xanatos and Fox had planned the Pack's break-out precisely to ensure this. Fox moved in with Xanatos at the Eyrie Building after leaving prison, and not long afterwards, they became engaged. ("Her Brother's Keeper", "Leader of the Pack")
The engagement present that Xanatos presented Fox with was the Eye of Odin, which transformed her into a sort of werefox that ravaged New York at night, while also draining her life-energy away. Xanatos and Goliath managed to save her in a temporary alliance, however, and it was during this adventure that Xanatos realized he truly loved Fox. ("Eye of the Beholder") Not long afterwards, Fox and Xanatos were married. ("Vows")
Soon after the wedding, Fox made an effort to ruin Halcyon Renard and presumably thereby secure Cyberbiotics for herself (she could have simply asked her father for it, but she considered the other way a lot more fun), by suborning Preston Vogel into sabotaging Fortress Two. Goliath foiled her plan, but she took it well, maybe in part because at that same time, she discovered that she was expecting (the baby that would become Alexander). Some time after that, Fox and Xanatos together set up the upgraded Pack, largely as a means of playing with the gargoyles for their amusement (Fox actually tipped the trio off so that they could rescue Goliath, Elisa, Hudson, and Bronx from the Pack). ("Outfoxed", "Upgrade")
During the Avalon World Tour, Fox went to Australia to set up the Matrix, with help from her mother (as a scientific consultant) and Dingo (as a security guard). When the Matrix went out of control, Fox received help from Goliath and Dingo in stopping it. ("Walkabout")
Fox returned to New York afterwards, and not long thereafter, gave birth to Alexander Fox Xanatos. It was then that Anastasia revealed her true nature as Titania, and decided to take Alex away to Avalon to have him magically trained; she was disappointed that her daughter had apparently learned no Third Race magic, and did not want the same fate befalling her grandson. The gargoyles, Xanatos, Renard, and Puck all joined forces to stop Oberon from carrying out Titania's instructions and kidnapping Alexander, but all failed; when Oberon had overcome all the rest of the opposition and was about to snatch her child out of the cradle, Fox in desperation summoned up the magic buried deep down inside her and blasted Oberon with it. Goliath used her act as a means of persuading Titania to let Alex stay in the human world. Fox was still angry with her mother for attempting to kidnap Alex, even if the resolution had ended happily, but Titania hinted that getting Fox to use her halfling magic was her real motive and whispered something in her ear, before departing. ("The Gathering" Part One, "The Gathering" Part Two)
After the gargoyles moved back into Castle Wyvern, they and Fox have done what they can to mend their bridges with each other, particularly Lexington, mainly because of Alex, whom they both have strong bonds to. It remains to be seen how well they will fare. ("The Journey")
Fox's most prominent distinguishing characteristic is a tattoo shaped roughly like a fox's head, over her right eye. She bore this tattoo even in her "werefox" form.
Alongside being a wily and determined figure (and worthy mate for Xanatos thereby), Fox is also well-read. (She likes the writings of Jean-Paul Sartre, but considers Nietzsche too "butch" for her tastes, and Kafka reminds her too much of the cockroaches that Hyena liked shooting rubber bands at in their prison cell).
Like her husband, Fox has a love of the game. However, she's not as acquisitive as her husband. He'd always take the path of least resistance to a goal. For example, if Renard would give her the company, Xanatos would suggest she ask for it. But she doesn't care about the company. Only the game. Xanatos likes the game. But he's about results. Fox is in this just for kicks.
She is also an excellent fighter, as her former role as leader of the Pack would attest. She is also a skilled helicopter pilot, as she has seemingly replaced Derek Maza as her husband's personal pilot.
Fox did not take her husband's last name, she's still just Fox. One word. But she does not object to being referred to, when WITH her husband, as "Mr. & Mrs. Xanatos" or as "David and Fox Xanatos". Though it would be more correct to say "Fox and David Xanatos". 
At CONvergence 2014, Greg Weisman revealed that Fox is bisexual.
Fox wears size nine shoes, and is fond of manolos.

Fox appeared in "Ransom" where, after Alex was kidnapped by Pat Doyle, she uncharacteristically cried and screamed like a stereotypical damsel-in-distress. She calms down when she is reunited with her son.
By the time of "Broadway Goes to Hollywood", she seems to have relocated her spine and engages in a silly plot to make Broadway a TV star by flying him out to Los Angeles (because the talk shows filmed in New York City are not convenient). While there, she ends up battling Jackal and Hyena after somehow commandeering Robyn Canmore's exo-armor.
Fox, along with the rest of her teammates escape from prison after a villain, disguised as Dingo, busts them out as part of a plan to kill Xanatos.
Behind the Scenes
Voice Actor: Laura San Giacomo (uncredited)
Alone among Gargoyles voice actors, Laura San Giacomo went uncredited for providing the voice of Fox. This was because her agent believed it would damage her reputation to have worked on an animated series, although Greg Weisman has said that Laura herself was "nothing but wonderful, working on the show. A real pleasure." Also, Laura gave birth to her son Mason at approximately the same time as Fox gave birth to Alexander.
