In her old appearance, Molly, like her twin brother, Molly is brightly colored, has four arms, and has three spots under her eyes to resemble how a spider normally has eight eyes. She has big voluminous hair that is supported by a hairband, she wears a double shoulder-padded suit with sleeves that extend to the palms of her upper set of hands, she wears striped gloves that reach the arms of her lower pair of hands. Unlike Angel, who only possesses four arms and two legs, Molly possesses two sets of legs as well as an additional set of arms.
Angel is Molly's twin brother. It's unknown what sort of relationship the two have outside of being blood-related.
Vivziepop stated that their relationship is positive and that she can't say much because a lot of that is after the Pilot.
Arackniss is Molly's older brother. It's unknown what sort of relationship the two have outside of being blood-related, although it is implied to be negative.
Molly is confirmed to have a father, but it's unknown what sort of relationship the two have outside of being blood-related.
Molly is confirmed to have a mother, but it’s unknown what sort of relationship the two have outside of being blood-related.
- Though she has yet to appear, Vivienne confirmed Molly is canonically Angel Dust's sister. She is still in development, but is tentatively planned for the series, along with Angel Dust's other family members.
- 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.
- Molly, and in extension, Angel Dust’s birthday are under ambiguity. According to Vivziepop, she initially recalled it as April 1st, but later revealed she does not remember the true date.
