Green Lantern #109

This oversized 44-page issue from 1978 promises urgent, planet-scale stakes, with Mike Grell's cover depicting a winged creature called Replikon looming over a desperate Green Arrow, who shouts that Replikon has destroyed Earth's ozone layer and that radiation is killing everyone. Black Canary and another figure lie stricken in the foreground, while the Original Green Lantern — shown in chains on the left — adds yet another layer of peril to an already dire situation. The bold tagline "Who Will Survive the Assault on Replikon?" makes this Denny O'Neil and Mike Grell team-up a genuinely compelling pick for fans of socially conscious superhero storytelling.
