20. Elliot Salem & Tyson Rios (Army of Two)
It's tempting to fill out this manful slide with a whole host of bro puns, so I will. BrOkami, Madden BrO5, LegBro Star Wars, Shadbro of the Colossus, Spybro the Dragon, Tony Hawk's Bro Skater 3, BrOverboard!, Broject Gotham Racing, Bro Evolution Soccer, Ha(y)Bro: Reach, Brome: Total War, Bro One Lives Forever, MariBro Kart, Brony PlayStation, no wait that's something else entirely… The point is that Army of Two's steroid-addled pair are so damned macho, they make everything else around them just a little more ballsy.
Salem is the smart, strong and tactically astute soldier. Rios is his impetuous, over-eager bud (though no less deadly for it). Together they bridge the gap between straight up buddies and the classic sensei/learner relationship. Rios gives Elliot a good chuckle, and in return Salem yells at his friend to get that damn head of his away from any-and-all incoming bullets. It's a symbiotic thing, really. What's more, EA Montreal designed Army of Two as a fully-fledged co-operative experience all the way from the ground up, meaning these boys were meant to be together. So much so that forsaking your partner, even for a moment, is a sure-fire way to get the both of you killed. Plenty of duos come unstuck without their bud, but few become so irrevocably screwed as the AoT boys. Oorah!
