Dabbler might be a little much for a Masks game (actually her powers are probably fine).
Halo/Sydney’s would be… challenging? maybe? but her character’s personality would be awesome fun - a great Outsider, in that she’s an outsider from supers-society and totally nerd-girling about that world all the time.
In fact… the general character concept of ‘total nerd-expert on supers history/tropes, who never considered they might actually BECOME one’ is a fun idea for Beacon, Janus, Outsider, Legacy (going the Green Lantern approach), Protege… and somewhat more tragically, the Transformed. That’s pretty cool.
