Vic...he's got massive amounts of firepower and guns, and is of course a corpse and thus really hard to kill. Eddie is also pretty tough by virtue of being another dead guy, but if you pour enough sheer abuse into him, he'll just be too brutalized to get back up. Set is, of course, the Antichrist, but Eddie and Vic have a major advantage over him - they're not alive, and thus, have to be completely ripped to pieces to stop fighting. Set is alive, and thus, can feel pain and be killed. He's pretty badass, though, so it'd be a stretch, but I feel confident Vic can utilize the massive stockpile of arms granted to him by federal law and kick some ass.
