Biography
In the early summer of 2000, Black Knight while passing through Monterrey Park with fellow bikers Brother Blood (John DiMaggio) and Cree Lincoln (Cree Summers) stops at a convenience store, where she and her friends start tormenting two customers named Daphne Blake (Grey DeLisle) and Velma Dinkley (Mindy Cohn). Grabbing Daphne with Brother Blood, Black Knight holds her while Cree taunts Velma, making her ask for Daphne's earlier thrown wallet and call her "ma'am". When Cree eventually does give Velma the wallet, Black Knight and Brother Blood let Velma go.

Shortly, after having their motorcycles damaged by Daphne as revenge for troubling her and Daphne, Black Knight and her friends follow the two girls to the suburbs of Riverside, where Black Knight, keeping lookout signals for her friends to come out out of hiding when the coast is clear. Along with Brother Blood, Black Knight begins siphoning gas from Shaggy Rogers' red Mazda sedan, planning on using the fuel to set fire to the haunted house. When Brother Blood fills up a canister of gas, Black Knight grabs it immediately and heads to the haunted house, where she finds Cree Lincoln, who had earlier wandered off, happily swinging from a suspended rope and rake on the third floor of the old house for fun. Demanding Cree to get down and help her, Black Knight fails to notice Donald Walls (posing as Theodore Seville), grabs her by the hair, take her inside to the attic, and killed her in cold blood. Going into the haunted house to look for Cree, Black Knight climbs onto the third floor and goes to the attic, where she finds Cree Lincoln dead, having been pinned to an attic rafter by the throat with a sharp pitchfork.

Staring in horror at Cree Lincoln's, Black Knight is ultimately attacked by Theodore/Donald, who stabs her to death by the stomach with another sharp pitchfork. After murdering Black Knight in cold blood, Theodore/Donald rolls her corpse like a sushi onto the bottom floor of the old house and later hangs her upside-down from a dead tree. Black Knight's corpse, still suspended from the dead tree, is later found and eventually taken away by the paramedics.
