Taiwanese player 小灰 from the TW-Wrathbringer guild hasn't actually "beaten" MMO World of Warcraft, because you can't actually beat the open-ended game. But damn, his stats are impressive.
According to website MMO Champion, the player has completed all the achievements except for the recently added "BB King" and is the first player to reach 986/986 points listed in the armory.
His stats in the Armory revealed that he has killed 390,895 creatures and died 8,543 times himself. He has racked up 7,255,538,878 points of damage and has completed 5,906 quests. That's an average of 14.6 quests per day.
As website GamePro points out, 小灰 has only given 11 hugs and "LOL'd" just once.
Congrats?
