I picked up the TPB of JLA Year One on my last trip back home and recently re-read it. Going through it again, I noticed something...odd. Nearing the end, when the aliens come for the JLA, GL and the rest switch places to trick the aliens. But we find out later that instead of switching costumes or the like, Hal used his power ring to change their appearances. The hell? Since when can a power ring do that? As Hal or any other GL ever done something like that before?
