Green Lantern (1960) #207
Starring Guy Gardner. "Simple Minds!" is written by Steve Englehart and drawn by Joe Staton and Mark Farmer. The Green Lantern Corps (or what's left of it after the cosmic events of the Crisis on Infinite Earths) has settled on Earth and become more or less the darlings of the media as the world looks to them as heroes. Kilowog, in particular, took down the dangerous psychopath Black Rock on live TV so he's the latest video star.
Other develops, such as the sudden womanhood of Arisia and her even quicker romance with Hal Jordan, has the GL Corps questioning all that they knew. But before they can rest up and get their bearings, the group is attacked out of the blue by Guy Gardner, the renegade GL that no one likes. Guy is more than just a little mentally unbalanced and peeved off plenty about being treated like a prisoner by the Guardians of the Universe so there's no love lost between GG and the rest of the GLs. But the mysterious beauty Kari Limbo might just hold the key to calming Guy's tantrums and creating a hero out of the hysteric!
