Zoe Slater is the daughter of Kat Slater and twin sister of Luke, conceived after Kat was raped by her uncle Harry Slater, although she was raised as Viv and Charlie Slater's fourth child. Zoe spent most of her life believing her and Kat were sisters, and didn't find out she was her mother until 2001.f
Born in 1984, Zoe arrives in Walford with her family, presumed father Charlie , sisters Kat, Lynne and Little Mo, and grandmother Mo in September 2000. Over a year later, Zoe and Kat argue about Zoe's decision to move away to live with her uncle Harry in Spain. When Zoe screams "You cannot tell me what to do, you ain't my mother!", Kat tearfully blurts out "Yes I am". She then explains that she fell pregnant at 13 after Harry raped her. Zoe is shell-shocked, and Kat attempts suicide but is found in the park by Zoe and is rushed to the hospital. While Charlie, Lynne and grandmother Mo watch over Kat, Zoe runs away, unable to take in all the recent revelations.While away, Zoe contacts Little Mo, the only other member of the family who did not know about Zoe's parentage, who persuades Zoe to come home, but after another argument with Kat, Zoe leaves again. She ends up living on the streets where she is discovered sick and penniless by Roxy Drake, a pimp determined to recruit Zoe. Roxy provides Zoe with meals and cigarettes, finds her a flat and forces her to prostitute herself. Roxy and fellow prostitute Kelly Taylor dress and make-up Zoe, but she gets drunk and vomits on her client. Kat arrives the next day to take Zoe home, but Roxy tries to prevent her taking Zoe, so Kat headbutts her, causing the woman's face to bleed. As Kat was so young, she was told she only had one baby, a daughter who was born first. Minutes later, another baby was born (a boy) unexpectedly but Kat was told it was the afterbirth. Viv knew that Kat had been raped by Charlie's brother but kept quiet. Together, Viv and Kat's Nan Mo decided to give the baby away, naming him Luke Slater as Viv thought that Luke might of turned out like his father and she wanted to keep Zoe as she was born first and thought it would be right, also Viv said she could not of passed off being pregnant with twins. Luke was later adopted and named Dermott.
Zoe gets engaged to Anthony Trueman, but leaves yet again, returning several months later, this time with Kelly in tow, and her engagement to Anthony is broken off. Zoe falls in love with Dennis Rickman, but he is secretly in love with his adopted sister Sharon Watts, and they eventually reveal their relationship. Sharon and Dennis's father Den suggests that to keep Dennis, Zoe should claim she is pregnant, since Sharon is infertile. The plan works but Zoe worries Dennis will realize she is not pregnant, and he refuses to sleep with her. Den offers to sleep with her so she can get pregnant and pretend the baby is Dennis's. However, Dennis catches them in bed together and leaves, but not before telling Den's wife Chrissie.
Chrissie persuades Zoe to abort the baby, then tells her they should team up for revenge on Den. They get together with Sam Mitchell to do this, meeting up in The Queen Victoria. After Chrissie revealed to Den she was going to leave him, Den physically attacks Chrissie, smashing her head against a fruit machine. Zoe stops him by attacking him with a metal doorstop, supposedly killing him. She runs off and Sam goes after her to calm her down. However, he is not dead, and he grabs Chrissie. She hits him again with the doorstop, killing him. Zoe is led to believe that she killed Den, though Sam sees Chrissie kill Den and eventually tells Zoe, who punches Chrissie. Zoe leaves for Ibiza while Chrissie is charged with Den's murder, and Sam goes on the run shortly afterwards. In the end, Zoe and Kat finally establish a true mother-daughter relationship.
In 2015, it was revealed that Zoe wants to move on from Walford and doesn't want to see her mum ever again. Also, she has a boyfriend with whom she is very happy with after starting her new life abroad, she is also engaged to be married.
