Tilla

Tilla is an Imp circus performer and one of the known siblings of Blitzo. She appears in a poster in Blitzo's office along with photos of Blitzo's office "family".

Appearance
Tilla is a tall Imp demon with very small horns compared to her siblings. She shares the same eye color as Blitzo and Barbie Wire. Unlike her siblings, she has hair in this case long, black, shaggy looking hair. Given other perspectives of the photo, she appears to wear a dark red and white dress with black around the chest and dark elbow-length gloves. She also appears to wear a white scarf or similar type of cloth draped around her shoulders.

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

Barbie Wire
Barbie Wire is Tilla's sister. Aside from the fact that the two used to work 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 presumably blood-related as they have yet to interact in the show.

Trivia

 * Her only appearance so far is in the poster in Blitzo's office with a third Imp named Barbie Wire
 * In "Spring Broken", it is mentioned by Verosika that either Tilla or Barbie Wire was with her during her stay in rehab.
 * Additionally, the poster of the three Imp Siblings that can be seen in the background of the I.M.P office used to showcase the three in the pilot episode but is somehow changed to now exclude Tilla starting from "Spring Broken" for unknown reasons.
