Bon is the ghost of a man accidentally killed by Jack Walten while hunting. Miraculously, his soul remained on Earth and he decided to take revenge on the Walten family, he took control of robot "Bon the hare" which is 7'2 feet tall. Unfortunately, he first killed the non-Walten family, Susan and Charles, employees of Bunny Smiles Inc. Then he killed Jack, who came to the restaurant to kill Bon. Then, a few days later, Rosemary came to the restaurant looking for her husband, but Bon convinced her that he was Jack and ultimately lied and killed her. He doesn't know that Guest is Jack because he thought he sent him to hell, but Jack got a chance to take revenge on Bon as the ghost of his old friend, Guest, and kill him. Of course, Jack (aka Guest) has the ability to change forms as a ghost and rule Wonderland. Bon also created Wonderland which is a place that holds all human souls killed by bon. His ghost form is a man in a suit with a hole under his neck and above his chest, showing how he died from a gunshot wound from Jack. He's smart, but revenge blinds him. He likes to joke about Jack and Rosemary even when she's standing next to him. Although he mentions twice a day how beautiful wonderland is. Which is not true because Wonderland is just a wheat field with some buildings from the lives of Bon's victims

Sha is actually Rosemary Walten. Sha's body holds the body of Rosemary Walten, which was dismembered by Bon. Bon transferred Rosemary Walten's soul to Sha, so now Rosemary Walten is Sha. She knows full well that Guest is her husband Jack and loves him very much, but she hides it from Bon. She hates Bon for killing her. But she has to cooperate with him just like Jack. She died after being manipulated into thinking Bon was Jack. Bon ripped off her arms and head, dismembering her. Her ghost form is a sheep with sewn-on arms and head, which shows how she died. She is serious but knows how to have fun. She is quite smart and thoughtful, but she always does what Jack (Guest) tells her to do cuz of love.

Banny is actually Susan, Bon's first victim in time order. She was (and still is) a friend of Charles. She knows Bon killed her, but she partially doesn't care anymore and has accepted the fact that she has to work with him. Bon killed her by snapping her neck, as shown in her ghost form, which shows her only with a snapped neck. It has Susan's body inside it. She is the smartest of the bunch. She likes to ignore others and doesn't care, she's quite secretive and doesn't even care

Boozoo is actually Charles. He's Susan's (Banny's) best friend. He's smart but tends to get angry quickly, so many people think he's stupid. He died fighting Bon; his ghost form has a sprained wrist because of how Bon treated him. He hates Bon for killing him but has to work with him. He tries to help everyone who comes here

Rocket is just a doll that sometimes shakes when Edward and Molly from Wonderland try to say something very forcefully. Edward (12 years old) and Molly (9 years old) are the children of Jack (Guest) and Rosemary Walten. They died in a car accident because Felix Kranken was driving them home from school while drunk. Now they are still in Wonderland and are so happy when Rosemary visits them (when she leaves the animatronic to go there). They don't know that Guest is their father Jack and they don't trust him, although Rosemary always tells them it's him, but one day they will believe.

Sophie Walten is the eldest daughter of Jack (Guest) and Rosemary Walten, and the last surviving member of the Walten family. She's around 20 years old now and sometimes comes to Bon's Burgers to see her parents. Of course, they do it quietly so Bon doesn't know because he wants to kill Sophie. She also prepares to kill Bon and free the souls of her parents, brother and sister, Charles and Susan, and others killed by Bon. She can't enter wonderland because she's alive

He was the one who crashed his car while drunk, killing Edward and Molly and Their ghosts haunt him. He works with Bon, but everyone except Bon hates him. He's alive and comes to Bon's Burgers often, protected by Bon.
