A few issues back, we noted Jack Kirby's return to DC in a CHALLENGERS OF THE UNKNOWN ad. Here he returns to the pages of ADVENTURE COMICS for a brief but bizarre run on GREEN ARROW. This first one is still very Batman-esque but things get weirder. Come to think of it, things were getting weirder in BATMAN by this point in the late fifties, also.
SPACE RANGER!!! Well, not all the SHOWCASE heroes were JLA material. Still, this guy lasted a few years in a couple of different titles. He just wasn't very memorable.
