Jackal is a character that appears in LEGO Spider-Man: The Videogame.
Prof. Miles Warren was once a professor of biochemistry at Empire State University. At some point, he studied genetics under the tutelage of the High Evolutionary, but was expelled from the Evolutionary's headquarters when he proved to be unstable. He received further training and equipment from Maelstrom. Warren fell in love with one of his students, Gwen Stacy, who was the girlfriend of Peter Parker. After Gwen was killed by the original Green Goblin, Warren turned his attention towards methods of cloning, inspired by the creation of a full-grown frog to attempt to clone humans. When he killed his lab partner Anthony Serba (who had discovered the truth), Warren became completely insane, developing the personality of the Jackal as he tried to convince himself that someone else had killed his assistant, rather than he.
In his first appearance as the Jackal, he attempted to manipulate the Punisher into killing Spider-Man (this was the popular anti-hero's first appearance), but when the Punisher learned of the Jackal's deception, he turned against Warren.
