Batman: Arkham city

Well, he was the first to vote to eliminate Tox. I wouldn't say it was solely based on his skills, as he could have had other reasons for voting. I don't think I need to explain further. So, most likely, he's not the Mafia (although I never rule out that possibility, and maybe Tox himself wouldn't mind that plan), but rather a Town member or a Neutral player... I can't be sure, but I'm more inclined to think he's a Town member. Besides, he often attacks me when I'm a Town member.
