Probably one of the three SUPER dudes. Rhue, Trazuin or Gaius.
It might be Dirk once Dirk reveals his obviously hidden super-powers (Come on! He can't just be a farty old man...can he?)
Scatha, Cetsa and Kloe don't really have the m4d skillz. They're too weak.
Slade would be AWESOME for the job, but he's washed up...and dead.
Strata is a possibility, but he's more likely a victim (In slashers, the cocky go first.
)
Alan? I wish, that would be hilarious.
Tetzel? Well if he's a forerunner, he's pretty buff. But for some reason, I doubt he'll even SHOW UP for some lame reason.
I hope for Alan, Slade (He comes back!) or Trazuin
