It’s rare that a major super hero is killed off. Captain America is dead. Here’s the context.
As the story notes, he’s not the first to die. Superman “died” in the early 90’s, but everyone knew that he would be back soon. The “superhero registration act” storyline sounds intriguing … and Iron Man is such a sellout! Maybe I should start reading comics again. I was never into Captain America, but that’s the benefit of these overarching storylines that pull in every character. You get to know characters you otherwise don’t pay attention to.
