Raiden's new design for "Metal Gear Solid 4" was a response to the criticism that only his face remained in his cybernetic body. Shinkawa was surprised by the way he illustrated Raiden. The staff noted that Raiden's debut in the game's trailer received notably positive responses; several video-game magazines promoted the game with Raiden's screenshots. Shinkawa stated Raiden was remade as a darker hero to appeal to the Western fanbase. Seeing Gray Fox as one of his favorite characters, Shinkawa made Raiden be an archetype of such character, making Raiden a cyborg like him. Kojima echoed similar comments, indicating he wanted to expand the character with another game. In designing him, Shinkawa wanted to convey both Raiden's beauty and sorrow in his cybernetic body. He was given the ability to wield swords with his own legs, giving the players the impression he was a ninja. Raiden's first fight against Vamp in the game caused motion and voice actors difficulty because of carefully planned movements performed by the two fighters. The staff was satisfied with the outcome, considering it one of the best battles in the game. Two actors were selected for the motion capture of Raiden; one did most of his appearances while another did his action sequences. Raiden's fights in "Guns of the Patriots" were made to assist the weaker Solid Snake and appealed to previous fans of the series who disliked the character. Because Raiden became a more active character in "Guns of the Patriots", Kojima expressed a desire in him returning in a future character as playable.
