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.”
In the Marvel Universe, the Avengers team is composed of superheroes who work together in order to save the world from dire threats. Although this group has been comprised of heroes over the years, some villains have entered into the fold, too, only to come out as heroes in the end. Some examples include Hawkeye, Quicksilver, the Scarlet Witch, and most recently, Red Hulk (or Rulk).
