Creation and development Early in Spring 2006, an official BBC press report announced the introduction of a new, all female family joining EastEnders, Denise Fox (Diane Parish) and her two daughters Chelsea (Tiana Benjamin) and Libby (nicknamed Squiggle), cast to Belinda Owusu, who was 16 at the time. Benjamin has revealed that she was the second Fox to be cast, and on her final audition, she had a workshop and met Diane Parish there. Owusu was cast at a later date. Tiana Benjamin who plays Chelsea has said that the three actors who play the Fox family have a bond, commenting "We all respect and understand each other, and manage to have a good time while we're filming too. I felt that we clicked from our first few scenes together."

Described as "the feisty Fox family", the characters first appeared on-screen in May 2006. An insider reportedly said to the Sunday Mirror, "They'll arrive in Albert Square with a bang and they'll cause friction from the off. The Fox girls don't take any nonsense -they'll be a force to be reckoned with." The newspaper described the character of Libby as a superbrat and teenage troublemaker. Owusu commented, "Squiggle is going to cause lots of mischief."

In April 2010, it was announced that the character had been axed along with five others by the new executive producer Bryan Kirkwood. Speaking of her departure, Owusu said: "I've had a great time playing Libby but I agree with Bryan that after four years of great storylines, it is now time for Libby to move on. EastEnders was my first real job and I have learnt so much but I am now really looking forward to trying new roles." Her final episode was broadcast on 5 August 2010.

In March 2014, it was announced that Owusu had agreed to reprise the role of Libby Fox for number of episodes from April 2014, as part of the "Who Killed Lucy Beale?" storyline.EastEnders spoiler, Libby Fox makes a return She made her on-screen return on 18 April 2014.BBC One – EastEnders, 18/04/2014 It was again announced in July 2015 that Libby would return again for a two episode guest stint.

Storylines 2006–2010 Libby is Denise Fox's (Diane Parish) youngest daughter. Libby secretly contacts her estranged father, Owen Turner (Lee Ross), an abusive alcoholic, and he starts making demands to see her. Denise is reluctant to allow this, but Owen seems to have changed, and Libby is keen for her parents to get back together; Denise is swayed and sleeps with Owen. However, as soon as Owen begins drinking again, he becomes abusive and hits her. He is arrested, but Libby persuades Denise to give a glowing character witness statement and he is released. Owen kidnaps Libby and takes her to Epping Forest. He drugs her and tries to kill her and himself by filling the car with noxious exhaust fumes. She escapes, but he catches her and tries to drown her in a stream. Denise arrives to find Libby unconscious on the bank. She is taken to hospital and makes a full recovery. Owen is imprisoned for 5 years.

Libby gets involved in various scams with her friend Darren Miller (Charlie G. Hawkins). She develops a crush on Gus Smith (Mohammed George), but is too young to be noticed by him, so she begins using an internet chat room, talking to a stranger named "Einstein27". She refuses to listen to Yolande Trueman's (Angela Wynter) concerns about the dangers of meeting someone online and agrees to meet him in person. When she meets the stranger, she discovers that she was chatting to Darren all along. He admits to liking Libby. She is initially unimpressed, but after Yolande arranges a meal between them, they decide to start a relationship. A few weeks later Darren visits his family in the Cotswolds, and Libby is heartbroken to discover he has decided not to return. She concentrates on her school work and achieves eleven good GCSE grades.

Darren returns some weeks later but Libby avoids him. When she finally plucks up the courage to see him, she hears him talking about someone called Clara. Thinking he has found someone new, she pretends she is going out with Tamwar Masood (Himesh Patel). It turns out Clara is a dog and the pair get back together. Libby and Darren have an anniversary dinner to celebrate a year of dating. However, Jay Brown (Jamie Borthwick) reveals that Darren frequently looks at pornography. Libby becomes furious and confides in Tamwar with whom she is in the process of starting a home tutoring business. Darren becomes jealous, but eventually reconciles with Libby and begins thinking about starting a sexual relationship with Libby. He invites her round to do this, however Jay ruins the night by telling Libby that Darren told him that she was a virgin. Libby is devastated, but she eventually comes round and she and Darren decide not to rush things.

Libby achieves A grades in her AS Level exams, leading Denise to declare that she will be applying for Oxford or Cambridge University. Libby worries her mother cannot afford to send her there. She later finds out she has conditionally been accepted at Oxford. Libby turns eighteen and Owen, who is still in prison, contacts her by sending her a birthday card and asking Libby's grandmother, Liz Turner (Kate Williams), to arrange a meeting. At the same time, Libby decides it is the right time for her to lose her virginity with Darren. She then phones her grandmother and agrees to meet with her father. Chelsea returns for Libby's birthday and sees Liz in the Square. Libby is forced to reveal that she visited Owen and that he will be released in a matter of months. Denise visits him but then tells Libby he will not be returning to their lives. Libby discovers she will attend Oxford University when she gets the A Level grades she needs but decides against it, saying her mother needs her in Walford. She later changes her mind, and leaves for Oxford early in October. Adam Best (David Proud), an Oxford student who has taken a liking to her, sends her a text message saying "See you in Oxford. X".

When Owen is released from prison, he returns to Walford to see Libby, although he is not supposed to. Denise's surrogate father Patrick Trueman (Rudolph Walker) discovers this and threatens to call the police, but instead he contacts Libby, who comes straight to Walford from Oxford to see her father. She overhears Darren booking a table for two in a restaurant and suspects he is meeting another woman. She turns up at the restaurant and finds Darren there with Owen. Darren says he wanted to ask Owen's permission to ask Libby to marry him. Libby accepts his proposal. When Lucas Johnson (Don Gilet), Denise's boyfriend and Chelsea's father, has Owen arrested for breaching his bail conditions, Libby at first doesn't believe Owen's claims but is shocked when Lucas confesses. Though angry with Lucas at first she eventually forgives him. Libby makes Owen promise to leave Denise and Lucas alone. The day before the wedding, Owen crashes Denise's hen night to warn her that Lucas killed his ex-wife Trina Johnson (Sharon Duncan-Brewster) and she is in danger.

Both Denise and Libby are angry with Owen. Owen is heartbroken and prepared to leave until Chelsea tells him about the bracelet. Unknown to everyone but Lucas, Owen hides in Phil Mitchell's (Steve McFadden) Jaguar and confronts Lucas about his crime, leading to Lucas strangling him to death and burying him in the gardens in Albert Square. Libby feels a bit guilty about parting on bad terms with her father but Liz reassures her. Darren receives a card from Heather Trott (Cheryl Fergison), which Libby opens and finds cash inside. Libby asks him about it and he says before Christmas he found Heather crying because she could not afford to buy any presents for her baby son George (Joshua Jacobs) and he felt sorry for her. Libby calls him a softie, but later overhears Heather and her friend Shirley Carter (Linda Henry) discussing Darren and the paternity of the baby. Libby reveals that Darren is George's father in front of everyone at Syed Masood (Marc Elliott) and Amira Shah's (Preeya Kalidas) wedding.

Darren tries to speak to Libby but Chelsea will not let him in. He continues to bang on the door while Denise tells Libby that she could go back to Oxford early and it is time to move on. Libby eventually talks to Darren, who explains why he slept with Heather and what happened between them. Libby then talks to Heather who says it was her fault it happened and she did not say anything as she did not want to hurt Libby. Libby then decides to leave and Darren stops her at the tube station and tells her how much he loves her, but she goes anyway. She returns from Oxford and tells her family she is now dating Adam, though Adam tells Darren that Libby she makes up for her lack of good looks by being good in bed. On hearing that Owen has supposedly sent flowers to Liz, Libby wonders why he will not get in touch with her. She steals some CCTV footage from the florists and is shocked to see Lucas ordering a huge bunch of lilies. Lucas explains to Libby that he sent Liz the flowers to buy Owen time because he is drinking again. Libby accepts this and hugs Lucas.

Libby goes back to university but returns when she learns that Lucas' son, Jordan Johnson (Michael-Joel David Stuart), is in a coma. She hears Ben Mitchell (Charlie Jones) confess in the middle of the café that he hit Jordan with a spanner and tells Lucas this. Lucas locks himself in the community centre and breaks down, blaming Jordan's condition on his own actions. Libby is worried about Lucas's state of mind and tries to coax him to come out. When she threatens to call the police, Lucas finally unlocks the doors. Lucas goes to the hospital and finds Jordan has been awoken from his coma and is safe. Libby tells Chelsea and Denise about Lucas's breakdown. Chelsea accuses her of making a mountain out of a molehill, Denise however listens intently.
