The King was a bloodthirsty, psychotic player who enjoyed torture, gladiatorial combat and Pictionary. When making a truce between the Knights of the Blood Oath he claimed that he wanted to raise money for Cancer Research by taking pictures of Asuna, but it's most likely that he just wanted to take pictures of Asuna in a bikini or something.[1]
Differences from the Original
Since the fight between Kirito and Heathcliff didn't end anticlimactically, the city of Collinia didn't devolve into chaos, meaning there was no bandits nor was there a player called "The King of Ashes" in original series.
