As long as Marvel's being overrun with Skrulls, how about a look at an Atlas-era Secret invasion? I've been reading Marvel Milestones vol. 68, Atlas Era Tales of Suspense, and especially digging on the vintage Steve Ditko art in several stories. I haven't really given Ditko his props around here, but the man was a true great. His off-kilter and unique art style has been a constant in my comics reading career, and while I can't say I've loved everything he's done, I've greatly admired his work and career. I've noticed that you don't see many Ditko copycats among lesser artists, as the man's very personal style is daunting to duplicate. All that said, I do tend to prefer his earlier work, and consider his '50's and '60's work to be some of his best. Here then, is "I Am The Changing Man!", a tale of green-skinned shape shifters attempting a strategic infiltration of the human race!
So back to the Skrulls. I've noticed that the timing is right for the Dethians to be possible prototypes for the similarly green-skinned shapechanging Skrulls. In fact, I'll propose that the Dethians rethought their whole strategy, reinvented themselves, and became the much-better-named Skrulls, who attacked Earth next in Fantastic Four #2 (1962). Where they were...tricked into running away from comic book panels. Anyway, that's my theory.
"I Am The Changing Man!"
