Following the announcement that Jared Leto was cast as Morbius in the upcoming standalone movie, we're here to help answer questions about the living vampire.
Morbius' vampiric origins stem from a blood disease he had throughout his entire life. He and his best friend worked together to try and find a cure and, pressed for time due to his impending demise, they rushed to try it out on Morbius and save his life. The medication worked in that it saved his life, but it also had some unforeseen consequences including giving Morbius vampire-like abilities and cravings.
Technically, Morbius is not a vampire because he's still alive (hence the moniker the living vampire), he just thirsts for blood and has super speed, super strength, enhanced perception, and the ability to fly. He doesn't share most of the typical vampire weaknesses though, like crosses, holy water, or garlic, and while he is sensitive to sunlight, it won't kill him.
Despite being an empathetic vampire who despises his own impulses, he initially takes up the role of the antagonist in the comics, feasting on humans and fighting against Spider-Man and the X-Men. He later develops more of an anti-hero vibe though, fighting to save innocent people while occasionally snacking on them himself. He is haunted by his own actions, and is eventually convinced to only kill people who deserve it, Dexter style.
