Gouken makes his first full-fledged appearance as a fighter in the arcade version of "Street Fighter IV", where he appears as a secret computer-controlled challenger. Capcom retconned Gouken's apparent death during his battle with Akuma. In Gouken's animated opening he reveals that after losing in battle to Akuma, he did not die but was simply rendered unconscious for an extended period of time. Gouken survived the Shun Goku Satsu by completely emptying his soul of emotions, which left him in a deep coma. He is shown watching as Ryu and Ken walk off, believing him, Gouken, to be dead. He is not concerned, however, what Ryu and Ken believe as he knows that their path is a righteous one and that he looks forward to reuniting with them once more someday. Gouken's mid-game cutscene show him confront Ryu, much to Ryu's disbelief, for a friendly master versus student spar in which Gouken is victorious. In his animated ending, Gouken faces Ryu again, finding that his student is being overtaken by the murderous energy, defeats him and suppresses, after which he notices Akuma is in the area. He also appears again in Akuma's animated ending. In this scene, after Ryu has been defeated by Gouken, Akuma appears and challenges his brother to a fight to the death with the winner claiming Ryu. Gouken also reveals that he has reached a new level of mastery known as and has now become even stronger, to the point where Akuma stops his Raging Demon attack after sensing Gouken's power of Nothingness.
