Tiffany Valentine (also known as "The Bride of Chucky") is a fictional murderous doll and the secondary antagonist in the Child's Play horror film series.
As a human, Tiffany has platinum blonde hair, a gothic fashion style, and a chest tattoo of a bleeding heart with 'Chucky' written above it.
When an argument reveals that Chucky had no intention of marrying her, an outraged and hurt Tiffany confines him in a playpen and taunts him with a Wedding Belle 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; Tiffany bribes a neighbor (Jesse) into transporting the "dolls" for $1000 over the phone.
Jesse and his newly-wed wife 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.
Just as Jesse is about to kill Tiffany, he notices Chucky holding Jade at gunpoint, forcing her to take him to the graveyard where his body is buried.
Just as they are about to complete the ritual, the police show up, prompting Chucky to confess his desire to remain a doll after considering the cons of being human.
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.
She storms out of the room, and later returns to find Chucky knocked down on the ground, unaware that moments before Nica briefly regained control of her body.
As an added surprise, she tells Nica that she bought the two of them a house in Hackensack, which in reality is Charles Lee Ray's childhood home.
Stuffing Nica in the trunk of her Pontiac, Tiffany drives to her newly purchased home to meet with realtor Gladys.
Holding a knife over her head, Chucky prepares to stab her, but stops when she reminds him that he needs her or their plan won't work.
When Nica/Chucky makes a snide comment back, Tiffany slaps him so hard that he falls to the ground, causing Nica to regain control.
When Chucky commands Junior to kill Nica, Tiffany finally snaps and proceeds to decapitate the doll with her nail file.
Picking up the head, she tells Chucky that she is done with him for good, revealing that she was the one who told the cops about him (Child's Play), before dropping him on the ground.
The next day, Tiffany poses as celebrity guest Jennifer Tilly at a special movie screening benefitting children's hospitals, held by Mayor Cross.
The mayor announces that as part of the benefit, seventy-two children's hospitals across the country will be receiving a priceless gift from Jennifer's personal collection of vintage Good Guy dolls, which will ship immediately after the movie screening.
After the movie is finished that evening, Tiffany meets with the truck driver to ensure the dolls are delivered to the airport before the plane leaves at midnight.
She walks back to her car but finds that it doesn't start, and she watches helplessly as Andy Barclay drives the truck away with the dolls inside.
Trying to take off the car fails to start and while being repaired Jennifer Tilly escapes only to be killed by an oncoming truck, making Tiffany incapable of transferring her soul.
They both decide to sneak Tiffany into the hospital to perform the Damballa chant to put Glen and Glenda’s souls back into their original doll.
Tiffany disguises herself as a doctor to enter into Glen’s room but before she has a chance to do anything the officer who was guarding the door walks in, recognizes Tiffany as Jennifer Tilly and is about to arrest her but Glenda smashes a flower vase on his head knocking him out then uses defibrillator paddles to electrocute him as the water he is drenched in causes his head to burst into flames.
Tiffany finally completes the ritual, leaving Glen and Glenda's human bodies devoid of their souls as they are combined into the doll.
Tiffany attempts to convince her that she needs the Wedding Belle doll because the Good Guys she donated for the charity event last year never made it to the intended hospitals.
Tiffany calls him despicable for killing a mother on Christmas Eve, and asks what Jake, Devon and Lexy are going to do now without any guardians.
As Lexy kills him, Tiffany walks past her and upstairs to Caroline's room to take the Wedding Belle doll.
In order to avoid suspicion, as Jennifer Tilly is still wanted for murder, she wears a black wig and dresses in a more gothic fashion.
Just before she is given the lethal injection, one of the guards loyal to her helps her escape the prison in a getaway car, with an enraged Nica giving chase.
Tiffany arrives at the house of Wendell Wilkins, original creator of the Good Guy and Belle dolls, and reunites with Chucky, who proposes.
