And if that’s the case, or even if she’s the offspring of two other speed-powered entities in the Arrow-verse, it stands to reason that Mystery Girl could and would be more powerful than someone who doesn’t have speedsters in their family history.
Still, Mystery Girl is the first character to show off dual lightning hues, which probably means she’s working with a different set of speedster genetics than we’re used to seeing.
And considering she has slipped into the protagonists’ lives as easily as she pleases, Barry had better hope she continues dropping off gifts instead of threats.
The most obvious presumption is that she’s a combination of Barry’s yellow and Iris’ purple as the live-action iteration of the couple’s quick-footed daughter Dawn Allen.
