In Batman: Arkham Asylum in the Cell Block room when you rescue Warden Sharpe (And receive the security hacker) there is a prisoner caged in a red straight jacket.
He can't be scanned, doesn't say anything (but makes a strange breathing sound) and seems to be more detailed than other thugs.
Who is this prisoner and does he represent anything?
Best Answer
He is the winner of the "A life in Arkham" (or "Your face in Arkham", not sure) contest from Gamestop, where the first prize was to have your face in the game:
So he's not a known villain, only a player integrated in the game. This explains also why he seems more detailled, he is made from actual photos (of the face, at least).
I can't find correct sources for this, only a few posts on some forums, because the original GameStop page is not valid anymore.
