Thanks to Kotaku for the above pictures as well as the bit of news that if you decide to pre-order Assassin's Creed: Brotherhood you will gain access to the Harlequin character above. Gamestop sums up the character pretty well : "Behind the gaudy costume and twisted smile lies the soul of a merciless Assassin. You call yourself the Harlequin. Your victims will call you a walking nightmare."
