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
Remarkably resembling her brother, 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

 * She only appears in Helluva Boss on a poster with her, Blitzo, and a third imp named Tilla advertising the trio as "The Amazing Imp Siblings".
 * Her name is a pun on "barbed wire".
 * In Spring Broken, it is mentioned by Verosika that either Tilla or Barbie Wire was with her during her stay in rehab.
 * The poster at I.M.P headquarters changes, and you can see only Blitzo and Barbie (with Tilla nowhere to be found) revealing that they are both twins.
