Barbie Wire

Barbie Wire is a circus performer and Blitzo's twin sister. She is a minor character who is first pictured in the Helluva Boss pilot.

She is also the former co-worker of Blitzo and Fizzarolli and the adoptive aunt of Loona, making her first official appearance in Unhappy Campers

Current
Being Blitzo's twin sister, she has a striking resemblance to him. Barbie is a slim, red Imp with large curled horns, red eyes with yellow sclera, sharp teeth and black, claw-like fingers.

Across her skin are white stripes, some forming crosses on her forearms as well as forehead. She wears a white and dark red, short striped dress with black, knee-high boots.

Young
As a child, she, like Blitzo, had a heart-shaped skull marking on her forehead. Though, it is also noted that she lacked the white markings she has as an adult.

Personality
Nothing is known about Barbie’s personality yet, however she appears to be somewhat rude like her brother, as she is seen flipping the bird in a poster. However, in Unhappy Campers, she is shown to have hatred for Blitzo, when she says she wants nothing to do with him.

Blitzo
Blitzo is Barbie Wire's identical twin brother. Aside from the fact that the two used to work together and had their own act in the circus, it is unknown what relationship they have outside of being blood-related, as they have yet to interact in the show.

However, it is suggested that Blitzo might have some good memories of their time working together in the circus, as he has a poster of them together in I.M.P.'s conference room as well as photos of them when they were younger on his hellphone, and inside of his apartment.

Barbie does not feel the same, as in Unhappy Campers, she wants nothing to do with Blitzo, telling him "Just cause I'm outta rehab doesn't mean I wanna see you. I never wanna see you, ever!" implying something happened to cause her to hate him to the point she seemingly disowns him as her brother

Trivia

 * Her name is a pun on "barbed wire".
 * Her first appearance was in the pilot in a poster in Blitzo's office, with a third Imp named Tilla advertising them as "The Amazing Imp Siblings".
 * In the official series, the poster was changed to exclude Tilla and the text was changed to be "The Amazing Imp Twins". The reason why Tilla had been removed is currently unknown.
 * In "Spring Broken", it is mentioned by Verosika Mayday that she was with Blitzo's sister during her stay in rehab, insulting her by claiming that rehab is for “sad, loser wash-ups". It is unknown if this is true or merely a fabricated insult.
 * In "Ozzie's", Blitzo has a picture of Barbie Wire and him as children, with their mother, who resembles Tilla.
 * She is the second character to get official merchandise before her actual appearance in the Helluva Boss series, following Andrealphus. In her case, an enamel pin.
