20 Greatest Spider-Man Villains Ever
11. Jackal
Miles Warren was first introduced as Peter Parker's college professor. However, he secretly had an unrequited crush on Peter's girlfriend Gwen Stacy. When she died, he went insane with grief and became the costumed villain known as the Jackal.
Jackal's expertise lies in cloning and was an integral part of the infamous Clone Saga. His obsessions with Gwen and Spider-Man have led to him making multiple copies of them, including Scarlet Spider and Kaine.
He also played a part in Spider-Island and a new version of the Jackal was involved in the recent Dead No More story, bringing all of Peter's dead loved ones and enemies back to life.
