Jack O'Neill was an android created by Harlan in the physical image of Colonel Jack O'Neill, along with doubles of the rest of SG-1.

1998[edit | edit source]

The team was forced to remain on Altair and the duplicate O'Neill told the original one that they would bury the Altair Stargate. (SG1: "Tin Man")

2001[edit | edit source]

Instead, O'Neill's double demonstrated that, in Major General George S. Hammond's words, he was as good at following orders as his "real" counterpart. He and the rest of the duplicate SG-1 went on missions themselves, until they were captured by Cronus on Juna. The original SG-1 came to the rescue and, with the doubles, managed to save the planet, but every member of the robot SG-1 was killed in some way. (SG1: "Double Jeopardy")

2002[edit | edit source]

The NID acquire the android construction equipment from Altair, along with the readings taken of SG-1, and use them to create their own duplicates of SG-1, in an attempt to create their own offworld teams that will do what needs to be done. Although the original, 'Alpha' team is essentially SG-1 with certain crucial information- such as the address for Earth- deleted from their memories, later teams were created to increasingly diverge from the original to create a team that would do the job the NID wanted, culminating in the creation of the 'theta team', a team consisting of ruthless versions of SG-1  based on the Goa'uld memory implants acquired from Junior, the theta versions of Carter, O'Neill and Teal'c being described as psychopaths interested in nothing more than their own survival. Theta Carter attempted to use a device based on the Quantum Mirror to perfect a new power source despite the potential damage the device could do to reality, but she was eventually destroyed by the android O'Neill when she failed, Theta O'Neill being apparently wiped from existence when his attempt to use the power source caused quantum ripples in reality.

The Gamma team, unlike their Theta team counterparts, bided their time with O'Neill and Teal'c vanishing. After Carter and Daniel were transported to the NID's Beta Site, they killed the NID officials except for their leader Carlos Mendez before O'Neill and Teal'c returned, having found a suitable base for the team. Sharing his original self's hatred for Mendez, O'Neill killed him with a pistol, but not before he was lightly damaged and Teal'c destroyed by P90 fire. Carter and Daniel departed with the power equipment they would need to continue their existence and destroyed the duplication technology so that no one could ever use it again, but O'Neill chose to remain on the Beta Site and allow his power to run out. When the real SG-1 arrived, O'Neill had already deactivated. Upon his chest was a message in Daniel's handwriting reading "you're welcome," referring to Gamma team's disposal of the Rogue NID cell.
