Miles Warren (Earth-1624)

Miles Warren is the teacher of Peter Parker and Gwen Stacy. While a teacher, he was attracted to Gwen. After Gwen's death, he blamed Spider-Man for the death and used his DNA to create clones: Ben Reilly and Kaine. When he saw that the clones were of Peter Parker, he learnt his identity and attempted to destroy Peter. However, Ben and Kaine betrayed him and spliced his DNA with that of a Jackal.
