Morbius, the Living Vampire, introduced in The Amazing Spider-Man #101 (Oct. 1971), became the starring feature with Adventure into Fear #20 (Feb. 1974), and continued through the rest of the run. After a single issue by writer Mike Friedrich and penciler Paul Gulacy, Steve Gerber wrote several issues in which Morbius went on a picaresque interdimensional journey and fought the Caretakers of Arcturus and was advised by the eyeball-headed character I. Doug Moench and Bill Mantlo followed, successively, as the feature’s writers. Its round-robin of artists included Gil Kane, P. Craig Russell, Frank Robbins, George Evans, and Don Heck. Back up reprints shortly resumed in issue #20. Morbius would receive his own short-lived comic-book series in the 1990s.
