After looking at hundreds of comic book covers, it becomes quickly apparent that not every cover is 100% original. Whether done intentionally or even underhandedly, there’s something about uncovering these “swipes” that adds a new element of fun to reading and collecting comics.
Avengers #70 featured the first major appearance of the Squadron Sinister (and their first cover appearance). It was a team of villains meant to be analogous to DC’s Justice League. Hyperion = Superman. Whizzer = the Flash. Doctor Spectrum = Green Lantern. Nighthawk = Batman. An alternate universe version of the team, the Squadron Supreme, has since been more prominently featured in the Marvel Universe and included even more heroes that were derived from DC characters.
