Tilla

Tilla is an Imp circus performer and the mother 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 with very small, completely black horns. She has yellow sclera and red irises like Blitzo and Barbie Wire. She also has long, black, shaggy looking hair. Also just like Blitz and Barbie she has the same marking on her forehead.

In the Pilot poster 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 implied to possibly be Tilla's son. Aside from the fact that the two used to work together in the circus alongside Blitzo's 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 implied to possibly be Tilla's daughter. Aside from the fact that the two used to work together in the circus alongside Barbie's 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 first appearance was in the "Pilot" in a poster in Blitzo's office with a third Imp named Barbie Wire advertising them as "The Amazing Imp Siblings".
 * In the official series the poster was changed to not include Tilla and the text was changed to be "The Amazing Imp Twins". The reason why Tilla had been removed is currently unknown, but she has since reappeared in the episode Ozzie's.
 * In "Spring Broken", it is mentioned by Verosika Mayday that either Tilla or Barbie was with her during her stay in rehab, although which of them it was is currently unknown.
 * Assuming it was Tilla, Verosika also insulted her by claiming that "rehab is for sad, loser wash-ups."
 * In "Ozzie's", Tilla is shown in Blitzo's phone gallery with him and Barbie Wire. Blitzo then cries right after seeing the picture giving off the vibe that something either happened to Tilla or Barbie Wire at one point.
 * In the episode Ozzie's there is a picture of Tilla with Blitzo and Barbie Wire, who are both holding a card with "happy berth moma" written on it, possibly hinting towards Tilla being their mother rather than their sister.
