2. Francis from Left 4 Dead
Make no mistake, the shotgun-toting biker is a great asset to have when fighting the undead, especially given that Francis is immune to infection. But that help comes at a cost, Francis exists to hate--that and kill wave after wave of flesh eating zombies. He hates many, many things, and you will get to hear him endlessly list all of them..
As he walks through stages, Francis often points out another thing he strongly dislikes, much to the chagrin of his comrades. Among Francis' long list of hates: helicopters, Mondays, Canada, lawyers, vampires, sewers, parades, snow, birds, planes, the army, boats, islands, and goodbyes. With his continual listing of everything he doesn't like, is there anything Francis actually loves? He's fond of vests, and that's about it.
