ALIENS AND SO FORTH ROUND-UP 004

Now's the time that we start pulling aliens from the vaults! So look out for a lot of A-names for the next while! Not the first one though, because something has to come up organically.

Crillionites:

Hailing from the planet Crillon (which boasts the majestic Crillion City, natch), the Crillionites are a caste-based society in which the Lords of Crillon (like from the title of the comic!) rule over a slave population via some sort of divine right. This societal order is threatened by Professor Wendall Keene and his crew of space explorers: Hugh, Celeste, and the also-titular Ken Craig, but whether this is due to some innate sense of justice on their part or for some other reason is never quite spelled out in their one extant appearance, as things start in media res and Mort Cowen there presumably thought he could go back and explain what was going on a bit later. No dice, Mort. (Circus, the Comics Riot 001, 1938)

the Ancient Ones: 

It's that old staple of adventure, the ancient hidden civilization! Not all of them are different enough from regular humanity to qualify as an Alien and So Forth, but I reckon a society of prehistoric Antarcticans who retreated underground when the ice crept across their lands and have indefinite lifespans must surely count. The Ancient Ones are kind of boringly benevolent, but they do have a lot of gold, which inspires hero Rocky Ryan's crew to mutiny and thus provides a bit of excitement.

This also allows the Ancient Ones to show off their somewhat ghoulish hobby: collecting gold-hungry adventurers in suspended animation. Or possibly practicing human taxidermy. (Big Shot Comics 009, 1940)

Antarenes: 

The Antarenes, inhabitants of the planet Antar, have a problem: their sun has gone out. Their solution? Head underground and set out through the void of space with their whole dang planet to find a new one. Unfortunately for Earth, rather than one of the presumably many uninhabited stars in the galaxy the Antarenes have chosen Earth's orbit as the coziest place to pull up their planet, and the Earth is just going to have to move out of the way (and into the Sun), whether they like it or not. Fortunately for Earth, Marvo 1￮2 Go+ is on the case and Antar is rerouted back out of the Solar System to find somewhere elese to park.

One small detail that I appreciate about the Antarenes: as a society that seems to mimic the eusocial nature of our world's ants they of course have a Queen but we never see her, for the simple reason that she is way too important to let two weird randos just rock up and meet with her. (Superworld Comics 003, 1940)

the Ants:

Captain Tornado, along with Professor Bordani and his daughter Jane, are stranded on the extrasolar planet Barrang. They meet and shoot a variety of intelligent aliens while there, the first of which are these giant alien ants, who don't figure too heavily into the plot but who do engage in intraspecies warfare and melon farming. (Popular Comics 046, 1939)
