Every once in a while I hit a particularly dense seam of aliens and so forth and this week is one of those times.
Neptunii:
The Neptunii (and that name is a guess based on the fact that one guy uses "Neptunus" as a singular version of the noun) live in Neptunia, an underground kingdom that could be described as "a big cave" at the bottom of the Atlantic Ocean. There, they seem to just kind of fly around shouting, though this short comic book story might not give a full picture of their society.
There are a few points of interest about the Neptunii: they are both finned and winged, they all wear little horned circlets, they call their leader the "Sub-Ruler"... but the thing I am always struck by is just how much Prince Ikor and his pal in the above panel look like quirky characters from a late-90s webcomic.
Though Peter "the Fin" Noble becomes the ruler of Neptunia via a bit of impulsive regicide and remains so in his infrequent appearances to this day, to my knowledge the Neptunii themselves have not showed their faces since their first appearance in 1941. (Daring Mystery Comics 007, 1941)
Inus-Men:
The Inus-Men take their name from the fact that they are the inhabitants of the planet Inus. They are pretty regular-style cavemen, only more red, and are one of the many dangers faced by Dr X's niece Cynthia when her astral form is blasted willy-nilly through space by her most unethical uncle. (Startling Comics 001, 1940)
Jovians:
The Jovians of the year 3964 AC (sic) are an oppressed underclass who work in the radium mines of the human colony on Jupiter. They are unable to own weapons by law, are possibly disallowed from large gatherings or approaching humans (see the first two panels above where the "boldness" of the Jovians is discussed) and generally mirror the conditions of colonized peoples on our world. This all clearly sucks and is unjust, which is especially interesting because the comic it all appears in clearly considers it to be the natural order of things.
The Jovians are ripe for (and right to) revolt, and do so under the leadership of the evil Space Emperor. Once he is captured and revealed to be an opportunist by Major Mars they are returned to their place under the collective human thumb. (Exciting Comics 001, 1940)
Jovians:
Our second set of Jovians are also radium focused, but rather than mining it for their human overlords they use it to generate power, and having run out they are now demanding that both Earth and Mars hand over their radium supply or face annihilation. This draws the ire of space adventurer and Earth-Mars envoy Mitey Powers and he sets out with his entourage to resolve the situation.
The title of this story is "The Super-Giants of Jupiter," and I really appreciate that it lives up to the name. These Jovians are big, man. They're also pleasingly alien, with their fish heads and tendril hands.
I can only assume that it is the fact that the Jovians and their warships are so big contributes to Mitey's decision to commit a war crime against their populace by unleashing a swarm of Martian Poison Gnats that will breed uncontrollably and "[kill] off most of the people." It's a horrible crime, Mitey! Particularly as radium is one of the less-used radioactive elements today! (Superworld Comics 003, 1940)
