We got your aliens right here.
Martians:
While I think that we might have a couple of Fletcher Hanks aliens in our future, the number is definitely going down at a fairly rapid clip, so let's enjoy these here Martians while we have them. Like so many aliens, these guys are looking to conquer the Earth, and like so many Fletcher Hanks antagonists they have come up with a completely bonkers and over-the-top method of doing so: by stupefying the entire population with gas and then loading them all into individual rocket pods that are then shot into space to drift forever. This is a Whirlwind Carter adventure and thus set in an undefined future date, which means that the Earth's population is effectively a big question mark, but the Martians have to be firing off billions of these things, right?
Perhaps this is why these fellows look so satisfied as they look out over a conquered New York, because they have just put in a very hard day's work to get it.
Like I said: this is a Whirlwind Carter story, and the key thing about Whirlwind Carter is that he lives on Venus and is thus not present for the Martian gas attack. Carter rounds up the stranded Earthians and employs them as the crew of a space fleet to take back the planet using a combination of gas and hand-to-hand street combat.
It makes only a brief appearance in the issue, but perhaps the most intriguing thing that we see in this issue is the Martian vapor arm that is deployed to kidnap Carter's partner Brenda. Is it a creature? A technology? Something that Martians can just do? Throw these questions on the big Never To Be Answered pile. (Daring Mystery Comics 004, 1940)
Hawk-Men:
The people of Earth in the year 3090 CE are being troubled by a series of bright flashes in the clouds, and when troubleshooter Planet Payson flies up to investigate the cause he discovers a hitherto-unknown society of winged people called the Hawk-Men living in a floating city. The flashes turn out to be ray gun blasts, resulting from a war that the Hawk-Men are engaged in with a second, unnamed group of cloud-dwellers. It's not entirely clear whether the Hawk-Men are a separate species, an offshoot of humanity or simply a group of humans who have bioengineered themselves some wings and taken to the skies, but what is clear is that they were pretty directly inspired by Vultan and the other Hawkmen of Flash Gordon fame. Just look at this Brian Blessed-ass Hawk Commander, for gosh sakes.
Payson and his companions take it upon themselves to stop the war by invading the cloud city of the other side (unnamed, but led by a jerk named Buzzlark). They aren't particularly successful, but while Buzzlark is gloating over them after sticking them in some clear tubes, the Hawk Commander is able to sneak in and assassinate him. War over on account of coup t'etat!
Another technology shout-out: this zippy little one-man tank that Buzzlarks men patrol his city in. (Planet Comics 002, 1940)
Hawkmen:
Speaking of things that are pretty clearly inspired by Flash Gordon, I now realize that that is exactly what the Rocket's adventures in and around the Diamond Empire are, and what would a Flash Gordon pastiche be without some Hawkmen? These particular Hawkmen are introduced in the person of Prince Falkar, who meets the Rocket and the Queen of Diamonds during a pitched battle with some Lizard-Men and becomes their staunch ally thereafter. After a brief interlude with some Ape-Men, he brings the duo back home to the Hawk Kingdom with him.
Rocket and the Queen's visit to the Hawk Kingdom causes some Big Problems: Falkor's fiance Princess Abbie becomes in turn jealous of the Queen and then attracted to Rocket, and the latter's rejection of her in favour of the former inspires her to assassinate the King and take the throne for herself. Falkor is forced to flee his home for the Diamond Empire, and as of the end of the series is still waiting for a little help in reclaiming his rightful throne. (Pep Comics 004, 1940)
Headless Men:
When scientists discover a weird new asteroid, space adventurer Buzz Crandall and his aide Sandra Curan are sent out to investigate. They discover a species of humanoids held in servitude by a bunch of big pitcher plants (who are not really ever given a name other than Plants, so that's what we'll go with).
The Headless Men have been systematically bred by the Plants into small, low-intellect, easy-to-control creatures by the Plants, but the downside to this is that they are now too feeble to fix a problem that has developed in the solar concentrators that the Plants derive sustenance from. Buzz fixes this problem under threat and is immediately betrayed, and he and Sandra are eaten by the Plant king.
The Headless Men are not, it turns out, completely without volition, and rise up in defense of Buzz and Sandra. Under Buzz' direction the solar concentrators are repurposed into heat weapons that fry the Plant population instead of feeding them.
