Lieutenant in the United States military, second-in-command to John Sheppard on the Atlantis expedition's lead reconnaissance unit in the Pegasus Galaxy. Ford was 25 years old and enthusiastic during the expedition's first year, and experienced in traveling through the Stargate to other planets. Little is known of his past, though his experience with gate travel implies that he was at some point assigned to Stargate Command on Earth. He left behind family when he joined the mission to Atlantis.
During the Second Siege of Atlantis Ford was overtaken by a Wraith warrior who attempted to sap his life force from his body. A stray grenade forced the two over an Atlantis balcony and into Lantea's icy ocean. The explosion forced the Wraith's life-sustaining enzyme into his body at full-blast, keeping him alive while face down in the water for more than an hour.
When he came to, Ford found the enzyme had "blessed" him with super-human strength. While this gave him an improved physical prowess, his mental abilities made him feel superior to his colleagues, who he believed were trying to tame or reverse his new urges. In fear, he fled the city in a Puddle Jumper. Once off world he abandoned the now inoperable craft and made for the Stargate.
Ford tracked a Wraith commander to P3M-736, where he encountered Dr. McKay and several other Atlantis expedition members who were looking for him. His team wanted nothing more than to return him to Atlantis, but Ford felt he had to vindicate himself before getting trapped in the city again. Now on the run from Sheppard a second time, Ford allowed himself to get swept into a passing Wraith Dart's culling beam.
Upon his reanimation the Wraith quickly discovered they were unable to contain Ford, and he fled once more. This time he shared his power with several young men throughout the galaxy. A small band eventually formed and grew, establishing an outpost and collecting live Wraith for a continued supply of the enzyme. Ford and his new coalition use their super-powers for their own purposes, striking against Wraith, Genii, and other forces that stand in their way.
Several key members of Ford's coalition were killed while infiltrating a Wraith hive ship with Sheppard's unit. Ford himself helped Sheppard's team to escape captivity on board the hive, and is suspected to have perished when the vessel was destroyed.
