Is she groovy because she is achingly beautiful and curvaceous?
Is she groovy because she's the heir of the absurdly wealthy genius-tycoon Simon "Choke on My Pet Lap Snake!" Stagg?
Is she groovy because she's a hip, sassy, trend-setting jet-setter and goofy-footing hot-dogger, who once hired goons to attack Batman?
Sapphire Stagg is groovy because when her beau transformed from a sexy Josh Berstein- like hunk into a gruesome elemental monstrosity, her devotion to him wavered not in the slightest or even for an instant.
That is one groovy chick.
P.S. Except, of course, for that one time where she got ticked that Rex had broken up with her, so she married some other guy. Which, somehow, makes her that much groovier.
