ALIENS AND SO FORTH ROUND-UP 003

It's time for round three of all the various aliens encountered by Spacehawk in his crusade for justice in the year 1940!

Neptunian Dog-Men, Plutonians, Jovians, Lunarians: 

This gang of space pirates that Spacehawk and his pal Galar beat up are described as "screaming, bloodthirsty Neptunians, Plutonians and Jovians" and this is somewhat vexing because they are an extremely heterogeneous bunch who absolutely come in more than three distinct styles, but I reckon that we can do it. The Neptunians are described in a couple of places as "Neptunian Dog-Men" so let's say that they make up the bulk of the group, the light orange ones. With the exception of the camel-faced guys lugging hoses in the first panel above - they seem distinct and arbitrarily reading left to right I'm going to say that they are Plutonians, which means that all of the green lizardy guys are by default Jovians, even the one with tentacles.

The pirate captain is the Lunarian, and I have to say that I am a big fan of his segmented arms and big ears, but not so much of his attitude. (Target Comics v1 011, 1940)

Uranians: 

We only encounter the Uranians as represented by the evil denizens of a pirate city for jerks, so their horrible rat-man personas are really emphasized. It's entirely probable that there is a pleasant city full of nice rat men who do arts and crafts on the other side of the planet. (Target Comics v1 010, 1940)

Vulture Men:

Really enjoy the look of the Vulture Men, who come from a far distant star to skeletonize people and steal our planet. They've got bird legs for arms!

They also appear to not have an articulated jaw, as seen when they themselves are skeletonized as an ironic punishment by Spacehawk. How do they eat? Nobody knows! (Target Comics v1 008, 1940)

Spacehawk's Species: 

As revealed in the Galar entry of the recent Minor Super-Hero Round-Up, he and Spacehawk are both members of a human-appearing alien race from somewhere outside our solar system. Not much is known about this species: they have some degree of super strength as compared to humans, they can communicate telepathically and their lifespans are long enough that Galar and Spacehawk, having not seen one another for six hundred years, catch up like two old high school friends now in their thirties.

Mentioned but Unseen:
