Blizzard is making good on its word to include the late Robin Williams in an upcoming World of Warcraft build, as players have found a character named Robin <The Entertainer> tucked away in the game files.
Datamining through Warlords of Draenor's files turned up three models for Robin, including a djinn (Disney's Aladdin), a human female with a man's voice (Mrs. Doubtfire), and a human male with suspenders (Mork). There are theories floating around that the djinn will morph into the other two characters while putting on a show for players, although we won't know for sure until the expansion releases this November.
On the day following Robin William's death, fans petitioned the Blizzard to include a tribute to the comedian as he had been an avid WoW player through the years. Blizzard responded by saying that it was "working on it."
