In FORSAKEN lore, Elliot Builder once lived in a family of three: his father, Mr. Builder, and his sister, Mia Builder. He was the oldest and most dedicated employee at his father's pizzeria, Builder Brothers Pizza, which is also featured as a map in FORSAKEN. He worked every role in the restaurant to build his own wealth rather than rely on his father's financial success. However, the pizzeria became a frequent target for hackers, most notably 007n7 and c00lkidd, forcing Elliot to endure the chaos they caused. It remains unknown how Elliot ultimately ended up in damnation. Elliot appears as a yellow-skinned Robloxian wearing a red visor emblazoned with a black "ROBLOX" logo. He has a red employee uniform with a black undershirt and black pants, along with a usually worried expression. He is a healer class.

007n7 in FORSAKEN is based on the creator of one of the most notorious Roblox hacker groups, "Team c00lkidd". He created c00lkidd as an alternate account and developed the "c00lgui" script during 2014, which was used to cause chaos among some of the most beloved Roblox games at the time, such as Work at a Pizza Place. In FORSAKEN lore, 007n7 is the adoptive father of c00lkidd. However, at some point while c00lkidd was under his care, c00lkidd had started hacking, which he used to wreak havoc, and eventually went missing (presumably forsaken). 007n7 appears as a light skinned Robloxian donning the Burger Bob hat topped with the Headstack, a blue torso to represent a shirt, black legs to represent pants, and a picture of the Disembodied-botox Injected Face of Thomas the Tank on his torso.

Builderman is a short, gray-skinned Robloxian with a blocky body. He wears a Turbo Builders Club hat, a gray and black hoodie with the old Roblox logo, a red undershirt, and blue jeans. In-game, his facial expressions are variations of the Mr. Chuckles face, which his avatar wore from 2011 to April 2023. Builderman is based on the current CEO and one of the original founders of the Roblox Corporation, David Baszucki, who uses the same Roblox account name, Builderman. As one of the two co-founders of Roblox—alongside the late Erik Cassel—he continues to lead the company to this day.

In FORSAKEN lore, Dusekkar and Shedletsky, who is also a Survivor in FORSAKEN, were ambushed by 1x1x1x1, who presumably managed to kill Shedletsky. Heartbroken and very depressed, Dusekkar eventually met his end when he was taken into the world of FORSAKEN while sleeping. Dusekkar appears as a pale-skinned Robloxian with a grey sleeveless shirt and layered white robes that drape over his body, each piece marked with black, rune-like text running vertically along the fabric. The robes are secured by a brown belt with a gold buckle, which also holds a small pouch at his side. His head takes the form of a dark blue pumpkin, carved with sharp, angular eyes and a jagged mouth that glow a vivid yellow. From within, a yellow flame is visible, subtly illuminating the inner edges of the carved features. Extending from the sides of the pumpkin are two black, branch-like antlers. He carries a long wooden staff, held firmly as both an offensive and defensive tool.

In FORSAKEN lore, Shedletsky served as a Creative Director, forming close bonds with Dusekkar and Builderman and later marrying BrightEyes. He created Sword Fights on the Heights and adopted the alias Telamon as his swordsmanship persona. Over time, his growing arrogance and hunger for power, worsened by exposure to the Necrobloxicon, culminated in a selfish act that created the Killer 1x1x1x1, a physical manifestation of his malice and negativity that ultimately turned against him. How Shedletsky entered FORSAKEN remains unknown. Shedletsky appears as a yellow-skinned Robloxian with short, curly brown hair, known as the Roblox accessory Telamon Hair. He wears his signature white shirt, featuring an image of his avatar holding dynamite with the text "BLAME JOHN" on the front, and the phrase "Remember that time when I totally pwned you on SFOTH?" on the back. He also sports short, blue, vertically striped swim trunks with a white drawstring and cuffs.

In FORSAKEN lore, 1x1x1x1 is a 4th-dimensional entity consumed by hatred for the Roblox 3D world. They were born from Shedletsky's arrogance, amplified by exposure to the Necrobloxicon and a selfish act. 1x1x1x1 grew in strength by stealing versions of Shedletsky's Sword Fights on the Heights. Wielding the Venomshank sword, they can rot players' code, preventing normal respawns and turning victims into rotten zombies under their control. Eventually, 1x1x1x1 confronted Shedletsky with an army of corrupted minions. How they entered FORSAKEN remains unknown, but their determination to destroy Shedletsky and his allies is absolute. 1x1x1x1 appears as a slightly modified version of 1x1x1x1 from the 2024 Roblox event "The Games". They wear a green Domino Crown with a green "X" symbol on the front, along with a wide red cape. They also have green wristbands resembling chains, a green domino-shaped shoulder pad on their left shoulder, and a crown-like green marking around their neck. Their design keeps notable features from their former appearance, including a glaring red eye, a visible black ribcage within their green torso, a high-contrast visual effect, and dark green flames emitting from their body.
