Q is for Quartzite

Quartzite is a villain and member of Task Force X that's only made three appearances. She is recruited by Amanda Waller to replace Nightshade (who had left the team). She was a part of a team sent to capture Hawk (Sasha Martens) and Dove (Wiley Wolverman), who'd broke out of a US Airforce Base. She has dimensional travel, which I don't think is totally explained. Given her name I'm going to say that she can travel to and and from Gemworld.
