Tiffany Valentine

Tiffany sets up and murders a police officer in order to steal Chucky's remains from an evidence vault. Stitching and patching the remains together with new doll parts, she re-enacts the voodoo ritual which put his soul inside the doll. When an argument reveals that Chucky has no intention of marrying her, an outraged and hurt Tiffany confines him in a playpen and taunts him with a bridal doll. Chucky soon breaks out of the pen and electrocutes Tiffany in her bath, leaving her lifeless. He repeats the chant which transfers her soul into the doll. Stuck in the same circumstances, they need the Heart of Damballa (a voodoo amulet) buried with Chucky's human remains in Hackensack, New Jersey. To escape their doll bodies, Tiffany phones and tricks a neighbor, Jesse, into transporting these "dolls" for $1000.

Several people are gruesomely killed during the road trip. Tiffany's particularly creative murder of a con-artist couple in a bridal suite moves Chucky to proclaim his love and propose to Tiffany; she accepts and they have sex. Jesse and Jade become wanted for the murders as all evidence links back to them; Chucky and Tiffany reveal they are alive and take the couple hostage, needing new wheels they steal a Campervan. The hostages instigate a fight between Chucky and Tiffany, Distracted, Jade kicks her into the oven and Jesse throws Chucky out the window, Jesse spins out which ends with their stolen Campervan crashing. Chucky forces Jade to his grave site to retrieve the amulet, when Jesse arrives to trade Tiffany for Jade. Chucky does so but quickly recaptures the couple and prepares to transfer Tiffany's soul into Jade. However, touched by Jade and Jesse's love, Tiffany stabs Chucky in order to stop his evil plan and they fight. Tiffany is stabbed in the heart by Chucky, and avenged by Jade who shoots Chucky to death. As she lies dying, Tiffany gives birth to a bloody baby doll which attacks the crime investigator.

Chucky and Tiffany are brought back to life by their child when he reads the inscription on the Heart of Damballa. When they see he has no genitals, Tiffany sees it as proof the child is a girl and names it Glenda (feminizing the name, Glen, which Chucky had given to him previously). Now going by "Tiffany Ray", Tiffany plans to transport her soul into the body of Jennifer Tilly. They also plan to impregnate her and put Glen/Glenda's soul in the baby's body. Their plan is successful, as Jennifer swiftly gives birth to two babies, a boy and a girl. This works out perfectly as Glen/Glenda has a split personality: a sweet and caring boy, and a homicidal girl. However, Chucky decides to remain a doll, seeing that being human is not so great. Disturbed by this, Tiffany leaves Chucky, taking Glen/Glenda with her, causing Chucky to get angry.

Tiffany and Glen/Glenda go to Jennifer's hospital. Chucky follows them and hits her in the head with an axe for leaving him, thus killing her. However, at the very last minute, she successfully passes her soul into Jennifer before dying. Five years later, she is happily living in Hollywood while inhabiting Jennifer's body, and is raising the twins on her own. On the twins' birthday, one of the maids tries to quit her job because she is afraid of "troubled child" Glenda. Tiffany tells her she can go, but then beats her to death with her doll body. Her eyes then turn green while she evilly laughs. In the extended version, she then hides the body and tells Glenda to keep a secret.

Eight years after the events of Seed of Chucky, Tiffany's soul still possesses actress Jennifer Tilly's body. She does not appear on-screen until it is revealed that she was the one responsible for mailing Chucky out to Nica's home, facilitating his murder spree on the family he blames for his human death. She pays a police officer to get Chucky from evidence after Nica's trial and once he is in his car she jumps up from the back and slits his throat with a nail file. The status of their twins is never stated. Six months later, Tiffany mails Chucky to the home of Nica's niece, Alice, and he suffocates her paternal grandmother. Chucky attempts to transfer his soul into Alice and it is shown that the grandmother is still alive. Her fate is unknown.

Four years after Nica Pierce was falsely imprisoned, Tiffany visits her in a mental institution after she was framed by Chucky for the murders of her family which Tiffany helped orchestrate. She is revealed to be the legal guardian of Nica's niece Alice and came to tell Nica that Alice had died, supposedly of a "broken heart". She leaves Chucky as a gift for Nica, saying that it was a gift from Alice. She later calls Andy Barclay and delivers a taunting message about Chucky's growing "Cult".

Tiffany later kills a security guard outside the Asylum, slitting his throat with a nail file. At the end of the film, Tiffany is reunited with Chucky (now possessing the body of Nica) and the two reaffirm their relationship with a kiss. Tiffany expresses some remorse at Alice's apparent death and says it was nice having her around. Chucky/Nica replies by saying "fuck that kid" and then they both begin laughing maniacally, along with the Tiffany doll sitting in the back of the car, which is revealed to hold part of Tiffany's soul before they drive off into the night.
