Saw

In the first Saw film, Billy is seen on a television set by Amanda Young, telling her about the reverse bear trap that was hooked into her jaws, and explaining that the key to remove it is in the stomach of her "dead cellmate" (who is actually a heavily sedated man) lying in the room. After she disembowels the man and frees herself, Billy comes into the room on his tricycle to congratulate her.

Later, Adam Stanheight remembers seeing the puppet in his apartment when the lights went out. As he searches the dark rooms using his camera's flash, the puppet's eerie laugh rings through the apartment, and Adam hits it with a bat until it stops.

When Detectives David Tapp and Steven Sing discover Jigsaw's latest hideout, they remove blankets from several covered items, one of which is Billy.

Saw II

In Saw II, Billy is seen on the screen at the beginning of the film, giving Michael Marks hints about the death mask he is wearing.

Later, when the detectives discover Jigsaw's new hideout, several officers walk up a caged staircase and are greeted by Billy, who wheels into sight at the top of the stairs on his tricycle and laughs. The cage then becomes electrified after one officer steps on a rigged step that breaks his legs.

Saw III

In a flashback in Saw III, Jigsaw is seen constructing Billy for Amanda's game, painting the puppet's face. Later, Billy appears on videotape to inform Troy and Detective Allison Kerry of their respective traps.

Billy is also used to remind Jeff Denlon of his dead son, by appearing next to his tricycle in the same position Jeff's son was in when he was killed. The puppet gives a mocking laugh until Jeff beats it into silence.

Saw IV

Billy is first seen in Saw IV when Officer Daniel Rigg awakes after being attacked in his apartment and rendered unconscious. Rigg opens his bathroom door, pulling a trigger wire from a TV set. Billy appears on the screen to explain Rigg's game. Upon leaving the room, Rigg is greeted by another message concerning his first test, referring to a woman Jigsaw deemed to be a criminal, who had been placed in a machine that would scalp her.

Agents Peter Strahm and Lindsey Perez later find Billy in a room in a school, sitting on a chair surrounded by candles. From a microcassette recorder hung around the puppet's neck, Perez learns that her partner will soon take the life of an innocent man (later revealed to be Jeff Denlon), and that her next move is critical. Billy's eyes begin turning to Perez. She leans in to hear this last, at which point Billy's face explodes, blowing shrapnel into her face and neck. Perez collapses into Strahm's arms as Billy laughs.

There is also a flashback of Jigsaw giving a less menacing, early version of Billy to Jill Tuck as a gift for their unborn son Gideon. An interview with Tobin Bell revealed that this was the beginning of a storyline concerning Billy's origins, as that of his tricycle, to be explored in future Saw films.^[5]

Saw V

Billy appears in the opening sequence to tell Seth Baxter the rules of his game. It is unknown how Mark Hoffman created the videotape for this game. According to a list of potential Jigsaw victims, Seth was the third person tested after Cecil and Mark Wilson. In those tests, Jigsaw did not use a puppet. However, Jigsaw's testing spree had already begun beforehand, as shown during the events of Jigsaw, where Billy does appear.

Billy is also seen at the beginning of the tests designed for Ashley, Luba Gibbs, Charles, Brit, and Mallick.

Saw VI

In Saw VI, Billy appears on tape in the opening trap, which pits Simone and Eddie against each other. He also addresses William Easton during two of his four tests. He appears in William's second test hanging from a noose, and on videotape in the fourth test. Saw VI marks the first time Billy appears "in person" to deliver test details to victims.

Saw 3D

Billy appears in Saw 3D. He gives Brad and Ryan instructions for their trap in person (and is covered in Dina's blood when she is killed by the trap), does the same for Bobby Dagen's second test, and appears on videotape for the others. When Hoffman goes to his hideout after killing Jill Tuck with the reverse bear trap, multiple Billy heads can be seen. Billy's final appearance is in Hoffman's secret hideout at the end of the film; Hoffman blows it up, destroying Billy in the explosion.

Jigsaw

Billy appears in Jigsaw with illuminated red eyes. He appears on his tricycle with a letter around his neck with the word "Confess" written on it. He later appears on a videotape with his eyes illuminated, explaining to Ryan how he can save Anna and Mitch before they are buried alive in grain.

Spiral

A photograph of Billy is seen in Spiral, while the film's Jigsaw copycat killer and main antagonist, Billy Emmerson (portrayed by Max Minghella as an adult and Leonidas Castrounis as a child) is named in tribute to the puppet. Masquerading as police detective "William Schenk", Emmerson showcases his own new puppet "Mr. Snuggles", inspired by both Billy and the pig motif of the previous films.

Saw X

After Valentina failed her test, Amanda tases Mateo and restrains him on a wheelchair, putting an open mask around his head and an electrical circuit around his torso. Afterwards, Mateo was reeled into the warehouse lobby with the rest of the group and was set next to a television, showing a live feed of a camera above his head, where some hair is shaved off in preparation for Mateo's test. Moments later, Billy enters on his signature tricycle, reeling a tray of various surgery tools consisting of a scalpel, a bone drill, forceps, and other tools, alongside with the tape recorder with a "Play Me" message on the tape.

After Mateo fails his test, Billy appears next to Gabriela with a similarly marked "Play Me" tape around his neck ready for her game to commence.

Non-canonical film appearances

Dancing with the Stars

On season 30 of Dancing with the Stars, the Halloween/horror-themed episode featured Amanda Kloots performing while costumed as Billy. The show, however misidentified the character being portrayed as "Jigsaw".

Video games

Billy, voiced by Tobin Bell, appears throughout Saw: The Video Game, delivering hints and objectives to the player. He also featured prominently in marketing for the game. In the "Freedom" ending, Billy's reflection is seen on a TV when Tapp commits suicide. He returns in Saw II: Flesh & Blood, the sequel to the first game, also voiced by Tobin Bell. Billy repeats his role as in the first game, giving hints and clues to the player. The player can also collect small Billy dolls throughout the game, which require solving more complicated puzzles to obtain them; they are off of the main path, so the player does not have to get them. Saw II: Flesh & Blood is also the only time in the Saw franchise that he is actually called "Billy".

Billy the Puppet is featured on some cosmetic items, such as a car decal, in the popular free-to-play online game Rocket League from 19 October 2022 as part of the Halloween update titled "Haunted Hallows".

Billy is in the video game Dead by Daylight as a prop as part of the Saw chapter. He appears sitting on the character-specific prop boxes that appear in maps when the player chooses "The Pig", a licensed character from Saw (who is Amanda Young in her Jigsaw apprentice reliefs).

A costume of Billy was added to Call of Duty: Modern Warfare for Warzone operator Morte as a part of The Haunting of Verdansk event. A costume of Billy was added to Call of Duty: Mobile for operator Morte as a part of Season 9 Nightmare.

Amusement park appearances

Billy appears on numerous screens throughout the queue line of "Saw – The Ride" at Thorpe Park, England, telling riders that they are not worthy of the life they have been given, implicating the ride to be one of Jigsaw's traps. He also appears on his tricycle at the start of the ride itself; the second dispatched car (two cars are dispatched one after the other) will stop while Billy gives a speech, informing the riders that there is no escape, and proclaiming, "Here's what happens when you lose", before allowing the train to pass – this regulates the distance between cars. He can also be seen before the car travels up the lift hill, appearing on a screen and saying "Game over", and at the end of the ride, where his head can be seen on a shelf covered with body parts.

The former "Saw Alive" maze, also in Thorpe Park, allowed parkgoers to be photographed with Billy.

In the U.S., Billy appears several times in the maze "Saw: Game Over" at Orlando Horror Nights at Universal Studios Florida.
