That story from April-May 1942 showed the Dynamic Duo landing Dick’s new miniature batplane on an island that appears—to the Boy Wonder at least—to be infested with living dinosaurs. Robin keeps saying he’s seen the giant creatures; Batman keeps telling him to stop talking nonsense. (More specifically, he snaps, “Don’t get gay!”) As shown above, Robin also falls down a bit. I’m not spoiling a good story when I ***SPOILER*** this one: there really are dinosaurs on the island, but they’re mechanical.
Dr. Joe Samachson. The Nichols character appeared in several more Batman time-travel adventures as recently as this decade’s “Time and the Batman.”
Joseph Greene is credited with scripting “The Year 3000” in Batman, #26 (Dec 1944–Jan 1945). This is an unabashedly futuristic adventure featuring Bruce Wayne’s distant descendant (and his young pal Ricky!) fighting an invasion from Saturn.
Thus, within a decade of his invention, Batman was involved in science-fiction adventures on top of his usual crime-fighting. The idea of Batman in space is usually associated with the “Silver Age” of DC Comics, starting in 1956. And indeed Pat Curley at Silver Age Comics has mapped the peak of stories in which Batman and Robin meet aliens (not including Superman himself) as from 1958 to 1963. But the tradition goes back to the 1940s.
At that peak time, Julius Schwartz was reinventing DC’s superhero universe with new sci-fi versions of old trademarks like the Flash, Green Lantern, Hawkman, and the Atom. Superman editor Mort Weisinger was reportedly leaning on Batman editor Jack Schiff to shift toward science fiction. When Schwartz took over the Batman books in 1964 with the “New Look,” he reversed course back to goofy crime stories, but he also integrated Batman and Robin into the larger, now sci-fi-driven DC Universe.
Thus, it was only a matter of time before Dick Grayson would have a hot alien girlfriend.
