“You know what's special about us? This thing we do? All of us inherited it from people who came before us. Without Iron Man, Captain Marvel, Spider-Man, and the Nova Corps, we wouldn't be here. So some people think we're the junior varsity, baby dress-up versions of the real heroes. But I like it. I like knowing that all of this is bigger than one person.”
