In the second season of Sword Art Online, we got to see Kirito defeat a seriously evil villain known as Sugo Nobuyuki AKA Oberon. During his virtual battle with Sugo, Kirito deactivated the pain absorber so that whatever pain Sugo would feel in virtual world would be felt in the real world. After seeing what this did to Sugo’s real body, all I saw was him being half-blind in one eye. In my opinion, the damage to Sugo’s real body should have been a lot worse considering what Kirito did to Sugo’s virtual body.
Kirito’s first strike on Sugo was across his left cheek. With the pain absorber deactivated, it should have made the left side of Sugo’s face sag and droop. The next strike chopped off Sugo’s right hand, which would have left his right arm dangling uselessly from his elbow and he wouldn’t be able to move that hand ever again. The third strike chopped Sugo’s body in half at the waist. This would cause a great deal of problems to Sugo’s real body ranging from a permanent limp as he walked, erectile dysfunction, and uncontrollable bowel movements. The final blow impaled Sugo’s head through his right eye. Obviously, his right eye would be blind, but Sugo would also suffer from extreme neurological damage similar to that caused by a stroke or seizure.
Overall, considering how much physical damage Sugo’s virtual body received and how much pain was transferred to his real body, Sugo should not have been able to move properly once he came back to the real world. Even if he made his final stand with Kirito in the real world, Sugo’s limp and brain damage would throw him off balance, his right arm would be a dead limb, and he would only be able to use his knife in one hand. That would have made it a lot easier for Kirito to take Sugo down.
