Nobuyuki Suguo is the villain who is responsible for keeping 300 Nerve Gear victims, including Asuna, prisoner even after SAO had ended. He did this by transferring them all into ALO for experiments regarding human subjugation via fulldive technology. That and taking over RECTO Progress Inc. by marrying Asuna while she is unconscious are his goals. In ALO he took on the identity of Oberon the Fairy King and made Asuna his queen, Titania. When he and Kirito finally meet, he flaunts his GM status as well as the results of his research by causing Kirito immense amounts of pain after increasing Kirito's pain limit and impaling him. He was defeated when the "Ghost Program" of Akihiko Kayaba reminded Kirito of how "he" was defeated by Kirito's determination. And then aiding him to overcome Oberon's GM status. After being defeated, all the 300 victims were released but Noboyuki still attempted to attack Kirito while he was en-route to Asuna in the real world. Was once again defeated by Kirito using what he had learned about combat in SAO to his advantage.
