Comic book aliens: one of the few inexhaustible resources.
Martians:
Just as Doc Strong and his followers are starting to get the post-apocalyptic, WWII-lasted-a-century world of 2041 sorted out, a bunch of robot-looking Martians show up to ruin things by invading their territory on the Isle of Right. It’s just one thing after another with that year.
Though they are fairly generic hostile invaders, these fellows really distinguish themselves among their class by immediately abandoning whatever plans that they had for Earth in order to indulge in a rager of a party. They want meat and they want booze, in that order and plenty of it. And as a bonus, the fact that the colourists at Blue Ribbon never really settled on a consistent colour scheme for these fellows means that the Party Issue is also the issue in which the Martians all look like they are wearing leopardskin briefs.
Everything works out okay, however. After Doc and his pals are taken back to Mars for judgment by the King of the Martians they learn that he is a mere robot shell built by friendly Earthman Stinky Jones, who is more than happy to lend his subjects’ might to the task of cleaning up the war-ravaged Earth. (Blue Ribbon Comics 007, 1940)
Masters of the Pit:
These inhabitants of the Pit of Horrors aren’t given a lot of characterization, seeing as they are acting as more of an extension of Fantomah’s rough justice than as a functioning society. They live in caves underneath the liminal Jungle and can shape stone with a word and a gesture, and that’s all we really get. (Jungle Comics 007, 1940)
Melubians:
The interesting thing about planet Melubia is the fact that they use gravity control technology to surround their world with hundreds of small artificial satellites on which are built small cities or individual dwellings. The less interesting thing about Melubia is the fact that there are two intelligent species living on it, one of whom (the Melubians) want to overthrow the rule of the other (the unnamed, more humanoid species headed by King Molat). We never really get a sense of whether this is a colonial situation or if the two groups evolved on Melubia in parallel, but either way, time/space traveller Stuart Taylor and his pals are quick to uphold the established power structure and put down the rebellion. (Jumbo Comics 016, 1940)
Mongonians:
The Mongonians, inhabitants of the planet Mongo (but a different Mongo than the Flash Gordon one) are some cool four-armed aliens with an unfortunate streak of paranoid xenophobia running through their society, as can be seen in their interaction with time/space traveller Whiz Wilson when he visits their planet in the year 2300 CE.
It may be that the Mongonians are on to something, however, as they are attacked by hostile inhabitants of the planet Zania just after they toss Whiz – along with two hapless explorers from Earth – into their jail. Everything eventually resolves nicely, as the explorers’ spaceship makes an excellent weapon against the relatively fragile ranks of the Zanian Balloon Corps and peaceful Earth/Mongo relations are established. (Lightning Comics v2 001, 1941)
