Jackal (Marvel Comics)

The Jackal is an alias used by several fictional supervillains appearing in American comic books published by Marvel Comics. Most are enemies of the superhero Spider-Man. The original and best known incarnation Miles Warren was introduced as a scientist researching genetics and biochemistry, and professor at Empire State University in The Amazing Spider-Man #31 (December 1965). Following the death of his student Gwen Stacy for whom he had developed an unhealthy limerence, he created his Jackal alter ego to seek revenge on Spider-Man who he blamed for the tragedy. To this end, he trained himself in martial arts, and created a green suit and gauntlets with claw-like razors, and later gained superpowers by mixing his genes with those of a jackal. The Jackal was introduced in The Amazing Spider-Man #129 (February 1974), but his human identity behind it was not revealed until The Amazing Spider-Man #148 (September 1975). The character is most notable for being one of the first in the Marvel Universe to master cloning technology, and creating various clones of Spider-Man, like Ben Reilly and Kaine Parker, as well as of other characters, including himself. He was popularized by storylines such as 1990s' "Clone Saga", 2011's "Spider-Island", and 2016's "Dead No More: The Clone Conspiracy", in which his experiments play a major role.
