Real name: Jack.

A VR-trained, digital-era special forces unit member, he was responsible for resolving the Big Shell takeover incident as a new recruit to the reformed FOXHOUND unit.

Before his solo infiltration mission on the Big Shell, his only combat experience was the virtual reality training he received in the US Army's experimental Task Force 21 Unit. At the time of his deployment, he was operating under the codename Snake, but his alias was quickly changed to Raiden after the discovery that the leader of the terrorists shared the name Snake.

His objectives for the infiltration mission was to rescue President James Johnson and disarm the terrorist forces. He was outfitted with the Skull Suit, with Rosemary and Roy Campbell providing support.
