Harry Mason is known for being the most badass underdog video game protagonist in excistence. Anyone who plays the game will know that this is a man who can whoop Master Chief's ass anyday. This is a man who will blindly run into the worst of horrors anyone can ever imagine without showing any sort of remote fear whatsoever, nothing less than the sheer determination for the only thing he gives a shit about: his daughter.
Harry beats the ever-lovin' shit out of any monster that comes in his way with an iron pipe or whatever else he has near him and doesn't complain. When he speaks, he is monotonous and unafraid and determined. Nothing breaks him, and nothing will stop him from finding his daughter. If you're in his way, back the fuck off, otherwise this fucker will beat your skull in with a pipe, stomp on your face while you're on the ground, headlock you, and ask you in a monotonous and calm tone: "Have you seen a little girl? Short, black hair?"
He's a dimwit sometimes, but redeems that by being totally awesome.
