Blizzard began working on a World of Warcraft tribute to Robin Williams almost immediately after his tragic death in August, and little more than a week later, what was assumed to be evidence of its efforts was discovered within the code for the beta release of the Warlords of Draenor expansion. Today, it appears those assumptions were correct, as Robin the Genie has been spotted in the game.
A petition calling for an in-game tribute to Robin Williams in World of Warcraft was met with enthusiasm by Blizzard, which quickly announced on Twitter that it was "taking care of it." And it really wasn't kidding.
A World of Warcraft petition requesting a new in-game character based on Robin Williams has been successful. That may seem strange at first, but Williams was reportedly an avid World of Warcraft player. According to the petition page, the late Williams used to play on the Mannoroth server, and "was something of a troll in trade on good days or when anonymity [was] allowed."
