The Flash #178

In "Double Danger on Earth!", the Flash of Earth-2, Jay Garrick, races to Earth-1 in a desperate bid to save his dying world after a comet’s radiation threatens all life. With Barry Allen by his side, the two Flashes use Jay’s urgent mission to track down and confront two of their most notorious foes—Captain Cold and the Trickster—before they can strike again.

In "Captives of the Cosmic Ray!", the Flash and Green Lantern are snatched from Earth by an alien vessel and stranded in a perilous other-dimensional realm, where they must navigate strange hazards and test their limits. With the help of a young woman named Carol Ferris and the resourceful Pieface, they uncover a chilling plot: the Myrmitons have been using their abduction as a cover to prepare for a full-scale invasion. Their return to Earth becomes a race against time as they race to stop the alien threat before it's too late.
