Z0rr0w is an antagonistic roleplayer, who tends to criticize every possible flaw or error noticed- with good reason, but still.
I honestly have no idea what happened here. Somebody get Z0rr0w on here, or write up some experiences you've had with him.
Z0rr0w is a very realistic roleplayer. He points out every flaw - scientific or not - and bashes the player until he succumbs. Though I must admit, he does quite a good job of getting the knowledge through everyone's skull.
