Who's This? There's a two-page spread of the Phantom Zone's denizens in Who's Who vol.XVIII. We're looking at the first half today.
He was the Kandorian who took on the Flamebird identity and hanged with the bottle city's Nightwing. I covered that dynamic duo in Reign of the Supermen. He once stole a sunstone, was sentenced to the Zone, but was released after he reformed (is that a pun?).
Who are Az-Rel and Nadira?
Who's Dr. Xa-Du?
Who's General Zod?
Who else? The other half of the entry of course!
