As a kid, my favorite book, up until 'X-Men,' was 'Avengers.' What does Captain America have? He has a shield. What does Thor have? He has a hammer. What does Hawkeye have? He has a bow and arrow. That's why Cable came with weapons. That's why Deadpool had swords and machine guns and pistols. It's like, let's weaponize these dudes.
