Hmm... Lieutenant Commander John Shepard, Captain John "Soap" MacTavish, Master Chief Petty Officer John-117, or Captain Devin Ross for the ABO? Perhaps Gordon Freeman, or even Duke Nukem... how 'bout all of 'em? Let's throw in Frank Castle too, along with Sergeant First Class Jack Kellar, Colton White, Kir Kanos, and Altair Ibn-La'Ahad! And Sam "Serious" Stone for seriously serious seriousness in the face of childish reverence of cartoon ponies!
"I have a galaxy to save. Excuse me." - Commander Shepard
