Morbius - The Living Vampire
Morbius, the Living Vampire, a.k.a. Dr. Michael Morbius, Ph.D., M.D.,is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Roy Thomas and originally designed by penciler Gil Kane, he first appeared as an enemy of the superhero Spider-Man in The Amazing Spider-Man #101 (October 1971).
Despite his initial status as one of Spider-Man’s horror-based rogues and also an adversary of the vampire hunter Blade, responsible for turning him into a dhampir, Morbius went on to become a brooding, gritty and tragically flawed antihero in his own series and other titles. His true identity is that of a former award-winning biochemist named Michael Morbius, who was imbued with pseudo-vampiric superhuman abilities and physical traits after a failed biochemical experiment which was intended to cure his rare blood disease, rather than originating from supernatural means. The rest of his appearances feature his struggles with his pseudo-vampiric persona, his insatiable lust for human blood and his subsequent efforts to cure his horrific condition, along with his eventual stint as a brutal and nightmarish vigilante, occasionally returning to villainy.
