Morbius is a fictional character that can be found in Marvel Comics. The character was created by writer Roy Thomas and artist Gil Kane, and made his first appearance in The Amazing Spider-Man #101 in October 1971. Dr. Michael Morbius was a scientist who sought to cure himself of a rare blood disease by using an experimental treatment involving vampire bat DNA and electroshock therapy. The treatment ultimately turned him into a pseudo-vampire, granting him superhuman abilities like strength, speed, and agility, as well as a constant craving for blood.

Throughout his comic book history, Morbius has been portrayed as both a hero and a villain, depending on the storyline and writer. In some stories, he is a tragic figure who is fighting to control his bloodlust and find a cure for his condition. In other stories, he is depicted as a dangerous villain who is willing to take down anyone who gets in his way.
Initially, Morbius appeared as a villain in The Amazing Spider-Man, where he was shown to be a bloodthirsty monster preying on innocent people. He frequently battled with Spider-Man and aligned himself with other villains like the Jackal and the Lizard.
However, over time, Morbius became a more complex character. In the 1990s, he was given his own series, which delved into his struggle to control his bloodlust and his quest for a cure. The series painted him as an anti-hero with a sympathetic backstory who was often at odds with both heroes and villains.
In recent years, Marvel Comics has depicted Morbius in a range of ways, sometimes as a villain and other times as a hero or anti-hero. For instance, in the “Spider-Verse” storyline of 2014, Morbius joined a team of Spider-Men from different universes in battling the Inheritors, where he was portrayed as a hero using his vampiric powers to help his allies defeat their enemies.
The 2020 limited series, “Morbius,” also highlighted the character’s struggle to come to terms with his vampiric nature and find a cure for his condition, presenting him as a complex and multifaceted figure.
In conclusion, Morbius is a character that has undergone many changes over the years and has been depicted in various ways throughout Marvel Comics. Although he was initially introduced as a villain, the character has become a tragic figure, a ruthless villain, a sympathetic anti-hero, and a heroic figure, depending on the story and writer’s viewpoint.
