Superheroes and love stories go together like peanut butter and chocolate. Virtually every superhero has a love interest (or two or three) in their comic book canon. Peter Parker/Spider-man has Mary Jane Watson and Gwen Stacey. Clark Kent has Lois Lane and Lana Lang. Bruce Wayne/Batman has Selina Kyle and Vicki Vale. Mr. Fantastic has the Invisible Woman. Everywhere you look, in comic books, in television shows and in films, a superhero has a love interest.
Sometimes, there can be a touch of disparity between the mediums. A couple might make it from comic book page to screen and be a success with audiences, as we’ve seen many times with Clark Kent/Superman and Lois Lane. Other times, the hero is given a new love interest for the screen, such as with Tony Stark/Iron Man and Pepper Potts.
