While most superheroes were born in comic books, some iconic characters originated elsewhere. This has happened with Marvel characters such as X-23 (a female clone of Wolverine) in “X-Men: Evolution” and Harley Quinn (the Joker’s love and right-hand girl) in “Batman: The Animated Series.”
What’s better than one superhero in a comic book? That would be two heroes in a comic, which is where the idea of team-up books thrives. Unlike a team book where heroes work together issue in and out, team-up comics focus on different characters working together for one or two issues max.
