Some guy who's been hanging out in the chat for weeks without saying a word. As he doesn't own a GameFAQs account (as far as we know), he's almost certainly a bot. The alternative is that he joined the chat and was murdered before he could say anything, and he hasn't logged out yet because his corpse has yet to be discovered. This makes for a much more interesting story.
Career on GameFAQsEdit
Oh wait, he's never been on GameFAQs! Silly me.
