engage with well-armed skeletal aliens
A perspective on old comics, new graphic novels, pulp magazines,
tabletop roleplaying games, science fiction, fantasy, movies,
and some other facets of geek culture.
Through Google, I found a PSA that appeared in DC Comics right after statehood (see here) but this is the earliest image I could find that has a major costumed character in the Aloha State - the Batplane flying across the islands. Unfortunately, I don't have anything more than the image: the panel appears on the DC Wikia page and in several aviation-oriented galleries of Batplanes, but I have no idea what Batman and Robin were doing in Hawaii. (They must have brought the Batplane over on a boat or in a bigger plane, right?)
My search did turn up one great Hawai'i sequence with a well-known DC Character: from Swanderful, a tumblr dedicated to the art of Curt Swan (and the tumblrator's perceived homoerotic content therein), comes this episode of Superman himself intercepting a space whatsis that is heading toward Honolulu. My guess is that this page is emblematic of most such visits to Hawai'i: some background images and few local geographic references layered over whatever crisis or combat comes next in the plot. Although to be fair, I guess that's not an uncommon treatment of any real-world locale in the DC Universe, or in the Marvel Universe outside of New York.
My RPG buddies all agree on the Loremaster character from the Pathfinder Core Rulebook. I have to admit that I see a resemblance in the face and even the expression. I could grow my beard out or get extensions, and I could even wear my glasses. But I think most people would just think I was a crappy Dumbledore; I would have to spend the whole time explaining the difference between Dungeons & Dragons and Pathfinder, and I am not sure I want to go there.
Dr. Druid began his career in 1961 as Dr. Droom, and in those early days of Marvel Comics, when creatures like Fin Fang Foom and his ilk were around every corner, he was a run-of-the mill monster-hunter. Eventually, he realized that Dr. Droom was a stupid name and changed it Dr. Druid, which is slightly less (or maybe actually a little more) stupid. In the seventies, he started showing up as a guest character in The Hulk and Ghost Rider (Hey, they both had movies, too! And sequels!) and joining the mainstream superhero jamboree. He hit the big time and became an Avenger in 1987. He went on to a long career as B- or C-list hero, and then all kinds of Epic Events® started happening, and he stopped calling himself Doctor Druid and became just Druid, because apparently that's purer and spookier or whatever and who cares because he was killed.
Until he comes back. Because that's the way continuity works these days.
