Or – “Vampires Seem To Operate On A Seven-Year Cycle…”
Back in the 60s, the sort-of-dreaded Comics Code Authority prohibited any mention of the undead. (There are many who claim, with more than just a little bit of evidence, that this was by design, to force EC Comics out of business a decade earlier.) Thus were Marvel’s revenants referred to as “zuvembies,” while the entirety of their vampiric activity was limited for some time to one Michael Morbius, whose pseudo-vamp powers were a side effect of a treatment to cure his strange blood disorder. With his 40th anniversary having recently passed, Morbius now graduates to his own book (again) and your Major Spoilers blood-sucking review awaits!
