Sarah Fox

Sarah Fox is the lead female of the live-action series, My Babysitter's a Vampire. She is the babysitter of Jane Morgan and Ethan (Jane's older brother). When she was turned into a fledgling by her ex-boyfriend, Jesse, she refused to feed on humans and remained a fledgling, while hoping to find a cure and become human again. Though in Re-Vamped, after Jesse bites Ethan, she saves Ethan from becoming a vampire by sucking out the venom in his body and ends up drinking his blood, turning herself into a full vampire. It's her third year in Whitechapel High.

Later on the last episode of the second season finale, The Date to End All Dates, Sarah dated long time secret admirer Ethan and they became a couple for a short period of time. The date ended when the guardian of the Lucifractor attacked them and turned the date into a disaster, on which Erica snarkily commented many times.

Background
Barely anything is known about Sarah's childhood life. Before her best friend Erica became a vampire, Erica hinted that Sarah is "a good girl. Straight A's, always nice to everyone." Sarah was just your typical seventeen-year-old girl who was a fan of Dusk the movie, which is a parody of Twilight, along with her best friend, Erica, until her boyfriend, Jesse, bit her and transformed her into a fledgling. While dealing with being a fledgling, Sarah meets Ethan Morgan and Benny Weir and the three of them defeat Jesse. Since Sarah refused to drink blood, she remained a fledgling until the episode ReVamped, when she sacrificed her remaining humanity and saved Ethan from turning into a fledgling while she turned into a full vampire.
