Tristant “Tiff” Valentine Ray is a psychotic man who enjoys killing people. He is Chucky's ex-husband, his ex-henchman and her ex-partner in crime, and the father of their children Glen and Glenda Ray. Back in 1988, it was later revealed that Tiff had been the one who told Mike Norris Chucky's whereabouts, which led to her being mortally wounded and resorting to transfer her soul into a Good Gal Doll. While Chucky is still a doll, Tiff had stayed in Jonathan Tilly’s body, and Glen and Glenda are in separate bodies than their doll one.

As a human, Tiff is a blonde beauty (though, his hair is naturally red like Chucky’s) with a slender figure which contains a deceptively muscular duality. He also has a tattoo of a stabbed and bleeding heart with "Chucky" written above his right breast. He is usually seen wearing dark attire, and bold makeup.

As a doll, Tiff’s soul inhabited a groom doll he gave Chucky to mock her back in 1990. The doll has green eyes and originally had black hair but Tiff dyed it blonde like his human body. He also gave the doll dark attire and makeover.

Tiff has a personality almost identical to Chucky: a profane, amoral, psychotic, and sadistic killer with no regard for any form of life. He is an expert in Voodoo arts and an intelligent and crafty serial killer. He is also a darkly-inclined individual who enjoys Bride of Frankenstein, amongst other activities. Upon discovering that he has a child, a new fatherly side seems to awaken within him. He immediately felt guilty about his murderous past and desired to change. He also tried to get Chucky to change too and became increasingly frustrated with her when she insisted that she and Glen and Glenda are all killers. He became even more upset with her when she was taking Glen on killing sprees behind his back. Despite this, he seems to revert back to his old ways. Tiff is a muddle of different styles. He dresses in dark fashion and can be described as a hopeless romantic. He has a "bimbo" air but is creative, inventive, intellectual, and somewhat feminist. His temper is short and he is struck sometimes by remorse out of sync with his love of killing. It is shown that he is a mama’s boy, who often takes on her logic when he says “Mother always told me love would set me free”. He is demure in a way that gives him a humanity more than Chucky, making them an unusual pair. Tiff's "ordinariness" is highlighted in several ways after becoming human in Jonathan Tilly, making him all the more compelling and dangerous. Despite his unforgiving nature, he still cares about Chucky. One might argue that beyond his "addiction to killing," his feelings for her prevent him from reforming despite his clearly having agency over his actions. Overall, Tiff remains as a heartless killer who continues ruining lives even after attempting to become a better person.

This time, he thought, this time, I will move on from her. That is what he kept telling himself, but he couldn’t. Not after everything they went through together.

In the grand mansion of Jonathan Tilly, Tiff—still known as Jonathan or Johnny by other celebrities—he was walking down a hall. He was wearing dark but casual clothes for once, still wearing bold makeup even now. He walked down to the basement, where he unlocked it using a key only he had for the whole house, and opened the door.

Inside, nobody would be able to see a thing apart from old stairs and a flickering light-bulb at the end. He walked down, the old stairs giving a creak with every one, with him humming a small tune under his breath.

When he got to the last step, he looked over the corner to which shown the basement. And there she was. His Chucky. Rope bound her plastic wrists up behind an old pipe, sat on her knees, head low. Tiff gave a soft hum, before walking over and bending down. “Don’t tell me you’re asleep still, dollface.” He spoke, his voice cool like he done this a hundred times. He probably has, knowing who he really was.

And with that, his hand placed under her chin, tilting it up to look.
