This plot seems too advanced for any of the known villains, though that cloak dude is unknown, why would he even need the puppet and mr self centered to help out if he can lure monster swarms?
I'm guessing he had them make the roadblock, so theres 2 questions, how would a roadblock guarantee them going around and if it doesn't, he would have to be able to call the monsters to the road, then why need a roadblock in the first place? And anyway does this mean the anti monster war is starting? Or just that agents of the monsters/monsters controllers are already acting before the war?
