Molly is Angel Dust's twin sister and Arackniss's younger sister. She has yet to make an appearance in Hazbin Hotel.

TRIVIA
* Though she has yet to appear, Vivziepop confirmed Molly is canonically Angel Dust's sister. She is still in development but is tentatively planned to appear later in the series, along with Angel Dust's other family members.
* She may appear later in the series, or at the very least be referenced; Viv said in her live stream that she wants Molly in the show at some point.
* Angel and Molly are fraternal twins and not identical twins.
* She is not a demon, nor is she in Hell.
* When asked if Molly is her real name or the name she has in Hell, Vivziepop said that Molly is her real name.
* Her name is a reference to the drug Molly, also known as Ecstasy. This might also reference her personality and cheery appearance, as Ecstasy causes users to feel immense emotional pleasure, energy, empathy, and altered sensations.
