A few years ago, they decided to kill Captain America. It was a big deal in nerd-world, and I remember hearing about it on the Colbert Report. (This is why Steven Colbert has a Captain America shield on his set.) It wasn’t a big deal though, because they brought him back. Superheroes never actually stay dead because the corporations that own the characters want to keep making money. They kill off their characters every now and then in a big “event,” which hopefully boosts sales. Then, after a while, they bring the characters back. Sometimes they are zombies, like in the Black Lantern hubbub. Other times, they just restart the story. Another way they do this is say that the story takes place in a parallel dimension where the superhero never even died in the first place.
