Green Lantern (1963) #90
"Those Who Worship Evil's Might" is written by Denny O'Neil with art by Mike Grell. Guest-starring Green Arrow. Ever wonder what the Oans employed to serve the cause of intergalactic peace before they came up with the Green Lantern Corps? So does Hal Jordan as he leaves the latest meeting of his fellow ring-slingers. But empowered with even more energy, Hal is anxious to return to Earth and resume fighting crime and so leaves his question unanswered, for now. Later, Green Lantern and his fellow-Justice Leaguer Green Arrow bake in the Sun in the desert southeast of Las Vegas. There, an atomic test has unearthed a flying saucer embedded in the sand.
Before long, the craft's door opens and a crimson-skinned alien clambers out, begging for aid and sanctuary. Behind him, three blue-skinned aliens of a different species spill out firing impressive ray pistols. But between Green Lantern's power ring and Green Arrow's exploding arrows, the pursuers are soon slowed down. Seizing his chance, the first alien shrinks himself and enters Green Lantern's ring, insisting that he be flown into outer space, to Calisto, one of Jupiter's moons. GL complies while GA keeps an eye on the trio of unearthly gunmen. On Calisto, the red-skinned alien (called Jinn) springs a trap on Hal Jordan and takes his Power Battery. The gunmen (or Hallas) explain to Green Arrow that they are intergalactic policemen (the Oans' predecessors to the Green Lantern Corps) and Jinn was their prisoner. Can the Emerald Archer and our hero sort it all out in time to catch Jinn once more?
