A lot of this was just sitting in a room thinking about what's the reality of a character like this was? He would have every weapon in the book, he would be relentless, he doesn't lose. When he’s sent to kill you, you’re dead. And the only one who can barely escape is Captain America.





If Captain America is the world’s greatest soldier, he is the world’s greatest assassin. He’s a doppelganger. These guys are equally as potent. Cap has a shield, he has a bionic arm. And they’re equally matched.
