The Definitive Superhero Thread for the Comic Book Fans

Thought I'd set up a universal thread for talking about any and all superheroes. Whether they originated in comic books, comic strips, graphic novels, normal novels, plays, pulp magazines, radio shows, TV shows, or movies, it doesn't matter. Any and all characters of the like are open for discussion. Talk about your favourite characters, comic book stories, graphic novels, movies, TV shows, episodes, whatever. Just have a good time.
