Sal has blue eyes and wears a prosthetic face which is usually seen as creepy by others. It is primarily white with a darker patch over the right eye. He keeps his bright blue hair tied up in two pigtails and has two piercings in each ear. Sal is most consistently seen wearing a black sweater, ripped red jeans, and blue and white sneakers.
While out in the snow he wears a pair of blue fingerless mittens and green earmuffs.
Throughout the series, he is also sometimes seen with his hair out of the pigtails, and in flash-forwards, he wears his hair down and is wearing an orange prison jumpsuit.
Sal is an adventurous teenage boy. He seems to be resourceful and has the ability to keep his cool during stressful situations, as seen through his interactions with ghosts. He comes off as friendly and polite regardless of rude or frightened responses he may get from people who are reacting to his prosthetic, and is openly affectionate of his friends. Sal frequently offers a listening ear or kind word to others, even to those who have been unfriendly to him, as evidenced in Episode 3 when he comforts a crying Travis in the boy's bathroom. His compassion and willingness to help people regardless of their appearance or standoffish behavior is demonstrated time and again. Though he is a kind person, Sal is capable of snapping back at those who try to hurt him through the use of sarcasm.
In Episode 3, his quick wit is demonstrated in response to bullying from Travis. He does not report the resulting punch in the face from Travis, however, and he does not correct comments made towards him out of ignorance rather than malice (such as when Miss Rosenberg misgenders him), suggesting that he doesn't like confrontation. He also does not seem to approve of violence, as he protests when his friends even jokingly threaten to kill Travis for bullying Sal.
In flash-forwards, Sal appears to be significantly more jaded and less trusting of others. He is well educated and enjoys learning, though he is seen seemingly wandering off in class. It is not known whether or not this is common.
Sal at Age 5
A month or so before Sal's move to Addison Apartments, the Fisher family went on a picnic to a scenic and sunny location, where a young Sal finds a dog and is eager to pet it. After some prodding, Diane consents and allows Sal to visit the animal. What follows is a mystery, but it is likely that the dog attacked Sal and injured him horribly. While the public seems to believe that it was the same feral dog that claimed the life of Diane Fisher, Sal is adamant that it was a man that took his mother away from him.
After a fateful visit to the hospital, Sal had to adapt to a new life with his prosthetic face and internalized the nickname bullies would later give him: Sally Face.
Sal's Move to Addison Appartments
Unknown circumstances ripped the two remaining members of the Fisher family from New Jersey and into the mysterious abode of Addison Apartments Room 402.
Halfway through unpacking, Sal decided to take a break, and, after sharing his feelings about the move to his father, left to explore the complex. After meeting the lovely Lisa Johnson Sal is introduced to heavy metal loving Larry Johnson who quickly became friends with the newcomer.
After Larry confided within Sal the details of Mrs. Sanderson's murder at the hands of Charley Mansfield, the boy is quick to offer his assistance. After devising a plan of action and receiving a Walkie Talkie from Larry, Sal returns to his room and a blackout drunk father to await his friend's signal.
After the officers are pulled away by a fake report of a robbery, Sal enters Room 403 and witnesses the carnage committed by Mansfield, the body outline of Sanderson, and an empty space between two Glitter Ponies.
Upon returning to Larry, they decided that they had to retrieve the stolen Glitter Pony from Charley and turn it into the authorities. A quick visit to Charley's room made it clear to Sal that the collector wouldn't let him anywhere near his toys, so he had to find another way.
When visiting the fifth floor, Sal finds old laxatives in the bathroom of Room 504 and the ghost of the young Megan Holmes, but the supernatural being is too scared to speak to Sal for long. Regardless, Fisher continued with his plan.
After adding the laxatives to a cup of Addison Tea, Sal managed to get Charley to abandon his watch over his beloved collection to attend to more pressing concerns in the restroom. Sal snags the toy and turns it into the Detective on the first floor. Mansfield is arrested and hauled away.
When Sal leaves the apartment to see Charley off, curiosity pulls him towards a coroner's van, where Sanderson decaying corpse lay, bagged, and awaiting processing.
Nightmares of Mansfield
A few months into Sal's stay at Addison Apartment, he begins to become plagued by nightmares. One particular dream places him at the picnic where his mother was murdered and shifted into Larry's shoes when he was fixing the toilet for Sandy Sanderson.
After being devoured by the toilet, Sal meets the Glitter Pony he used to incriminate Charley, begging for water. When the plumbing is restored, the Glitter Pony becomes bloated, serving as a bridge for Sal to return to the "surface" to witness Mansfield murder Sandserson. A trail of bloodied footprints leads to a seated Charley Mansfield, admonishing Sal for his actions. Sal is jolted from sleep when Charley's skin peels off to reveal a coal-black demon with red eyes.
A Dark Secret
Sal confides the details of his most recent vision in Larry, who is skeptical of the whole thing. Despite this, Johnson takes Fisher to his Tree House to tell him the story of his past. Sal immediately recognizes the Red-Eyed Demon from Larry's story (having seen it in the apartment's kitchen on his first day) and offers to help lift his "curse". After retrieving an enigmatic Puzzle Box from a trunk containing the possessions of Larry's father Jim Johnson, the two return indoors.
Meeting the Others
After a failed attempt to summon Megan Holmes from the bathroom of room 504, Larry refers Sal to Todd Morrison, the resident brainiac, and believer in the unknown. Sal, eager to show Larry that spirits do exist, doesn't hesitate to pay Todd a visit.
Upon entering Todd's apartment Room 202, Sal meets Ashley Campbell, a fellow student at Nocksfell High and quickly becomes enamored with her. After a brief farewell to Campbell, Morrison agrees to help Fisher by modifying his Gear Boy to better detect supernatural activity. After cannibalizing Larry's radio antennae and Walkie Talkie, the device was ready for testing in Todd's restroom. It was here that they draw out the weeping ghost of Greg Montague who is quickly scared away by Red-Eyes.
Todd recovers from the initial shock of the supernatural occurrences and advises Sal to test it further while he did some digging into the history of the murders in Addison Apartments. Sal's tests lead to the discovery of various symbols throughout the apartment complex and The Phantom of Jim Johnson. Sal doesn't share any of his discoveries with his friends.
When Megan remained hidden, even with the improved tracking device, Sal returned to Todd and learned that the officers that arrested Charley were not registered in the police database and the Charley Mansfield that was arrested looked nothing like the one they knew. Additionally, old reports of Megan's corpse being found by Lake Wendigo shows pictures of the girl when she was still alive.
Sal retrieves Megan's necklace from the same lost and found that held the Supernatural Gear Boy Cartridge, brings Larry back to Room 504, and uses the Super Gear Boy and Crucifix Necklace to successfully draw out Megan Holmes.
After yet another brief interaction that revealed a friendship between Jim Johnson and Megan's father Luke Holmes, she is scared away by Red-Eyes, leaving an awestruck Larry Johnson and Sal Fisher behind.
Sal and Larry agreed that the apartment room warranted further investigation. Larry left Sal to retrieve a crowbar from David, a former drug addict, while he returned to care for his sick mother.
A visit inside of David's Room 302 led Sal to the discovery of the missing piece to Jim Johnson's Puzzle Box. Before returning the crowbar to Larry, Sal solved the box to discover an odd Computer Chip inside. When the chip merges with Todd's computer, the Phantom gives Sal a garbled message about a "red ball" and morphing the Puzzle Box into a Rubix Cube, something that goes unnoticed by both Todd and Larry.
Using the crowbar to break into Room 403, Sal converses briefly with the spirit of the recently deceased Sandy Sanderson, before she too is frightened away by the demon.
Upon entering the hole, Sal discovers the eviscerated spirit of Stacy Holmes in an upturned bed's springs and the hanging corpse of Luke Holmes. When Sal attempts to speak with it, the corpse sheds its skin to reveal an agitated Red-Eyes. Before the demon could do anything it was removed with a special device created by Todd and used by an intervening Larry.
When the threat had clearly passed, Sal comforts a grief-ridden Larry for the "abandonment" of his father.
Nocksfell Math Examinations
Most of the events following the disappearance of Red-Eyes proved mostly normal for Sal, (sans the disappearance of multiple students) who had become good friends with Todd, Ashley, Chug, and Maple. Events returned to the paranormal on the final week before Nockfell High's finals.
Sal, having completed his math examination well ahead of the rest of his class, distracted himself with doodles, using the unusual events that he had experienced as a basis for his stick figures before dozing off. He is abruptly awoken by Mrs. Packerton who assures him that he did well on his test, earning ire from the Christian zealot raised bully: Travis Phelps. When the class reached its conclusion, Travis confronts Sal and Ashley in the halls and punches the former in the face, and drawing blood in the process. Sal declines all offers from his companions to get even with Travis, insisting that it would only worsen the situation with him.
Sal notes that the bologna being served tasted funnier than it usually did, causing his friends to spew their speculation over the meat's origin. Instead of leaving the matter a mystery, Sal opted to investigate and his group (sans Chug and Maple) agreed to help.
After being harshly turned away by a disfigured Cafeteria worker Kim Yazzie, Sal turns to alternate solutions. Suspecting that Kim was responsible for the bologna's condition, Sal teamed up with Larry and took a picture of the woman's file. As Kim Yazzie was a former Amateur Nature Photographer, Sal took a picture of a bird and presented it to Kim who was then willing to give the boy sample of the bologna and the identity of the school's supplier: Mrs. Packerton.
On his way back to the labs to test the bologna samples, Sal meets a weeping Travis in the restroom. Although Travis threatens the Sal, Sal stays and comforts him, assuring him that if he ever needed a friend all he had to do was ask.
After the bologna was examined, Sal's group concluded that they needed more information on where Packerton got the bologna. Before the lunch period was over, Sal and Larry broke into Packerton's classroom and opened her desk drawer to find many cult-like objects and a piece similar to Jim Johnson's puzzle box. Not long after Sal is plagued with another vision of The Phantom who delivers and indecipherable message before fading away.
The Investigation of Room 201
While Packerton was away, Sal and Larry broke into her apartment to find the severed head of a goat in the refrigerator and two locked doors. Behind one of the doors was Mr. Packerton, hooked up to a life support machine and stuck in a vegetative state. Sal uses the Super Gear Boy to summon Mr. Packerton as a ghost. The spirit denies knowledge of the bologna's origins and instead begs to be euthanized. Sal complies and pulls the plug.
After being forced into hiding by a late Ashley Campbell, whom they had mistaken for Packerton, Larry found a key to the next room: a butcher shop stained with blood, decorated with newspaper clipping of missing children, and a pentagram-decorated footlocker fridge. Sal opens the footlocker to find the deboned flesh of his missing classmates.
Disgusted, but satisfied that the origin of the lunchmeat had been uncovered they decided to leave and devise a way to deal with Packerton. Before they could complete their escape, Ashley discovers a hidden trash chute behind a picture of a farm and accidentally falls down into the bowels of the apartment building. Sal is plagued with panic and another indecipherable message from the Phantom.
The Cult's Temple
Sal and Larry retrieve Todd and enter a room in the basement concealed by the Lost and Found shelves. Although the room is vacant, for the most part, Sal discovers a cellar door leading deeper below ground. They enter the temple of the Devourers of God and station Todd at the entrance to keep the gate open. After navigating through temple's maze and pressure plate puzzle gates, Sal and Larry come across a pedestal before another gate.
Sal placed the piece he stole from Packerton into the pedestal which opened the gate, leading a room filled with piles of bones from the Cult's victims. Miraculously, Ashley was unharmed and discovered merely unconscious atop one of the piles.
After safely extracting Ashley from the temple, the group wanted to know what they should do to ensure Packerton can't harm anyone else. Much to Sal's horror, his friends suggest killing her. Sal convinces them to sleep on it, but the next morning they learn that there was no need to take action as Packerton was killed by a drunk driver on her way home.
The Sally Face Killer
An unspecified amount of time later, Sal Fisher, branded by the media as The Sally Face Killer, is currently being held in custody and awaiting trial for framing Charley Mansfield and killing unknown victims. Sal was assigned Dr. Enon as a psychiatrist by the courts to determine whether or not he was a victim of his own insanity. Sal had his brain picked by Enon, eager learn details of the convict's strange dreams and stories.
During his second-to-last session before his trial, Sal told Enon of his dream in the hospital and finding the corpse of his mother. While Enon writes it off as an "interesting dream" request that Sal shares the details of his first day at Addison Apartments. Sal complies but is initially unwilling to divulge any details regarding Larry Johnson after high school, but when he was willing to talk the session had ended.
In his last session, Sal shared his encounters with the Red-Eyed Demon and the ghosts of Addison Apartments with Enon who rejects the idea of supernatural involvement in his patient's life. When session time had elapsed again, Sal was dragged away shouting for Enon to investigate Larry's tree house with the promise of answers waiting there.
Three days before Sal's interview with Faux News Anchor Clare Nettles, he experiences another dream of The Phantom, this time speaking in understandable sentences. Sal then learned that Enon was dead and he had 73 hours left.
When Sal met with Clare, he affirms that he didn't want a lawyer and would be representing himself in the coming trial. Sal is told by Clare that the most popular question about him was his refusal to eat bologna. Sal reluctantly shares the full details of the Bologna Incident under two conditions: that the story be aired unedited, and he would be told of the condition of Todd Morrison.
Clare honors her end of the bargain and informs Sal of his friend's worsening condition. Sal begs to see him, claiming to know what was wrong.

- Sal is an estimated 115 lbs.
- Sal's birthstone is a blue zircon.
- Whilst Sal is male, he doesn't seem to care how people perceive him, or about traditional gender roles, as evidenced by his traditionally feminine hairstyle, and how he didn't bother to correct Ms. Rosenberg when she referred to Sal as a girl. In addition, on the alternate route of Episode 1, upon meeting Megan for the first time, she tells him "pigtails are for girls, silly!" to which he responds that nobody ever said only girls could wear their hair in pigtails, and that he likes the style, too.
- In Russian, Sal's nickname "Sally Face" is translated as "Salli-kromsali", which literally means "mangled Sally".

He never takes off his mask in public since he doesn't like the idea of others seeing his face. Steve Gabry equated the feeling of his prosthesis being taken off in public to the feeling of your pants being removed in public. While we're on the subject, Sal enjoys the moments where he is able to unmask himself and eat his food in private without having to worry about other people looking at him.
