Who's This? The sexy fantasy babe on page 1 of Who's Who vol.XXII.
How you could have heard of him: She was most recently seen in the Time Masters: Vanishing Point mini-series (2010), where she met Booster Gold, though she has been referenced from time to time, for example Swamp Thing #163 (1996) along with Claw and Nightmaster, and in Starman #55 (1999) where she may or may not have been saved by Starmen II and IV.
Example story: Starfire #2 (1976) by David Michelinie, Mike Vosburg and Vince Colletta

Who else? If you were paying attention, you'll know where I'm headed next.
