After Jack Walten's spirit becomes bound to Bon, the once-cheerful animatronic takes on a far more unsettling presence. Towering and eerily still, Bon moves with unnatural confidence, silently stalking his victims while carrying Jack's grief, rage, and desperate search for his family. His fixed smile and vacant eyes mask a tortured consciousness, turning him into a tragic yet terrifying figure whose every movement feels deliberate, relentless, and haunting. He was the one who killed Susan and Brooks, wanting to make them beautiful. Beautiful ment He put them in wonderland (in a animatronic suit so they'll be with him forever). He still loves Rosemary, and will do anything to keep her like the others.

Jack Walten is one of the central figures in The Walten Files, portrayed as the hardworking co-founder of Bon's Burgers and a devoted husband of Rosemary and father (of Molly, Edd, and Sophie) whose mysterious disappearance sets much of the series' tragedy into motion. Calm, determined, and somewhat controlling, Jack is remembered by those around him as a loving family man who wanted the best for his wife and children. He took Edd and Molly's disappearance hard, but he kept it bottled up.

Before the tragedy that shattered her family, Sophie Walten was a bright, curious, and caring teenage girl who deeply loved her parents and younger siblings. Though naturally a bit reserved, she had a playful side and enjoyed spending time with her family, looking up to her father, Jack, despite his busy schedule. Growing up in what seemed to be a warm, loving home, Sophie lived an ordinary life. But now, she just wants the past back.

Rocket is a small blue rabbit plush from The Walten Files who appears cute and harmless on the surface which was owned by Molly Walten, but is closely tied to some of the series' darkest and most mysterious events. Molly and Edd possessed the plush and now stays at Bon's Burgers after being killed in a car crash. Felix was drunk. It was his fault.

Felix Kranken is one of the central figures in The Walten Files and the co-founder of Bon's Burgers alongside his close friend, Jack Walten. Once an ambitious businessman, Felix's severe alcoholism, overwhelming guilt, and cowardice makes him a terrible person. He drank at a school party he took Molly and Edd to, and then crashed with them in the car. He buried Edd and Molly and told the police that, after the crash, they ran off. Despite appearing composed in public, he is deeply broken by his mistakes, making him a complex character whose attempts to bury the past only cause even more suffering.

Banny is the cheerful, energetic purple bunny mascot of Bon's Burgers, known for her upbeat attitude and friendly personality. Designed to entertain children, Banny is expressive, talkative, and always eager to help, making her one of the more lively members of the restaurant's mascot cast. Beneath her playful exterior, however, the ghost of Susan (one of the engineers at Bon's Burgers) possesses the robot.

Billy is a brightly colored clown animatronic from The Walten Files whose cheerful appearance contrasts with the series' unsettling atmosphere. With his striped outfit, oversized shoes, painted smile, and playful design, Billy is meant to entertain children, but now, Ashley's ghost (a girl who was simply exploring the place) has inhabited the robot.

Boozoo is the cheerful, round-faced ringmaster mascot of Boozoo's Ghosts, known for his top hat, tuxedo, and exaggerated stage presence. He comes across as loud, theatrical, and eager to entertain, but now Brook Charles's spirit (an engineer who worked alongside Susan) is now bound to the robot.
