She has lavender skin, long two-tone purple hair, red lips, aqua eyelids and green eyes. Her outfit consists of a dark purple dress with a knee-high slit, red flats, and a red belt. During exercises, she temporarily wears a red sweatband and pink leg warmers. She is tied with Phantasma as the second tallest girl in school, falling short of Elsa Frankenteen. She can turn into a bat like all other vampires.

Sibella's color scheme is incorporated into her bat form, as when she turns into a bat, she keeps her green eyes and aqua eyelids and has a lavender face, dark purple body, purple wings and red legs. Personality

She is very kind and courteous. She seems to only dislike the Calloway cadets, Grim Creeper, and Revolta (and garlic of course). She compliments other people often, showing she has good people skills. She is also very supportive, strong-willed, soft, benevolent, down-to-earth and selfless, as she spent the last of her allowance on a pizza for Shaggy, Scooby and Scrappy. Another account of her being cooperative is answering the door for Miss Grimwood while she was busy with Tanis. She is not, however, above using her bat form to her advantage in sports such as volleyball and racing. She has a frequent habit of making puns on words to make them relate to vampires, such as "Fangtastic to meet you." Powers and abilities

Sibella as a bat Sibella as a bat. As noted above, she can turn into a bat, which gives her the ability to fly. It has been shown that she can go out in the sunlight with no difficulty, though her father has to wait until the sun goes down before he can visit her.

She seems to be very creative with clothing, making a bat robe for her father and a fire proof one for Matches. Revolta also called her strong, when she was trying to mind-control Sibella after the other girls had been taken, but Sibella fought and was the only one who lasted so long, so she may be the most powerful ghoul.

She dances and swims very well.
