He is living onboard the airplane Nomad with Dr. Hal "Otacon" Emmerich and Olga Gurlukovich's daughter Sunny, a child prodigy in computer programming. Since the aftermath of the Big Shell Incident, Raiden has drifted away from Rose, who had apparently suffered a miscarriage with their child and gone to live with his former commander Colonel Roy Campbell, and has become a cyborg ninja fighting against the Patriots.
