Barbie Wire

Barbie Wire is an imp circus performer. Not much is known about her, other than the fact that she is Blitzo and Tilla's sister.

Appearance
Being Blitzo's twin sister, she remarkably resembles him. Barbie is depicted as a red demon with massive curled horns, crimson skin, and yellow eyes. Across her skin are white stripes, some forming crosses on her forearms. She wears a white and dark red striped dress for attire.

Blitzo
Blitzo is Barbie Wire's twin brother. Aside from the fact that the two have worked together in the circus alongside their sister Tilla, it is unknown what relationship they have outside of being blood-related (presumably) as they have yet to interact in the show.

Tilla
Tilla is Barbie Wire's sister. Aside from the fact that the two have worked together in the circus alongside their brother Blitzo as shown in one of the posters in Blitzo's office, it is unknown what relationship they have outside of being blood-related (presumably) as they have yet to interact in the show.

Trivia
