Marvel's Space-Born Superhero! Captain Marvel #5

From September 1968, this issue of Marvel's self-proclaimed "Space-Born Super-Hero" puts Captain Marvel in a seriously tough spot — the cover, penciled by Don Heck and inked by Dan Adkins and John Tartaglione, depicts a massive, blue-skinned creature with glowing yellow eyes and long, writhing tentacle-like limbs crushing the green-and-white-uniformed hero in its grip. Titled "The Mark of the Metazoid," the issue promises a cosmic-scale threat that makes you genuinely wonder how Mar-Vell gets out of this one. Writer Arnold Drake and artist Don Heck were delivering bold, imaginative adventure during an exciting early chapter of the character's run at Marvel.
