The "War Of The Worlds" feature in Amazing Adventures began in the title's eighteenth issue in May of 1973 and was published bimonthly for the entirety of its run, finally having its plug pulled near the end of 1976 after twenty-two issues--nineteen of which were scripted by writer Don McGregor, who worked with a number of artists before pairing with Craig Russell and putting their joint stamp on the book and the principal character of Killraven.
With Killraven and his band of Freemen leading the charge against the invaders and their human and once-human collaborators, it became clear almost immediately how the series was being crafted to appeal to its readers. For instance, when the guns of Killraven and his compatriot, M'Shulla, are depleted of energy (simultaneously, mind you), both men shift to a more daring approach and reach for swords and other such weapons (scooped up in a convenient museum they find themselves in) that must be wielded with a strong arm, and never look back--tools and methods reminiscent of their days in the gladiatorial pens of their youth. "Sword vs. Science Gone Mad!" declares one cover caption on its second issue (and repeated almost word for word nine issues later). It was also at that point I began seeing the Earth's Martian conquerors being pushed to the background, with the bulk of Killraven's vengeance spent on those who were imprisoning and/or experimenting on human survivors located in this complex or that.
As a result, the Martians become collectively relegated to the two-dimensional role of evil conquerors--known to feed off of humans while enjoying the spoils of conquest as they rule in tyranny. It's a rather black-and-white view of this invasion, and the invaders, that even McGregor seems to be on board with, judging by the opening page of his initial issue:
There is only a single issue in the series where McGregor and Russell would explore the Martians (or two of them, at least) in greater depth (more on that shortly); but in an effort to briefly shift the focus back to the beings who started this "war" (though at this stage it could more accurately be referred to as an "occupation"), let's collate what limited scenes are available in regard to their direct involvement, while taking a look as well at those chosen few who are unswerving loyalists to their demands.
