Theta

Artificial Intelligence Program Theta was an AI designed for the Special Operations program Freelancer, originally assigned to Freelancer North Dakota. He was the only AI that could run North Dakota's enhancement, his enhanced motion tracker, and, by extension, his domed shield. As Recovery Command was aware that North still had possession of Theta, it can be assumed that Theta was similar to the Delta AI, in that it was not deemed dangerous and removing it from North was not necessary. Theta was stolen by the Meta when he killed North. Being a fragment of Alpha, one would assume this AI was the embodiment of one of Alpha's personality traits.

Project Freelancer
Theta is seen in the fifth episode of Season 10, newly implanted into Freelancer Agent North Dakota. Theta appeared to be a timid AI, hiding behind North's leg. Theta appears to get along well with Delta, seeming happy to meet someone similar to himself. Theta is then seen running North's Domed Energy Shield during a simulation test. Theta tells North not to talk to him while he works or he will mess him up.

Recovery One
Recovery Command was aware that North still had possession of Theta, indicating that he was not considered dangerous. Theta was stolen by the Meta when he killed North.

Reconstruction
Theta was destroyed by the EMP with the rest of the Meta's AIs.

Trivia

 * Theta was given to North Dakota due to his caring nature being able to handle his timid personality.
 * It is possible that Theta is the "Inner Child" fragment of the Alpha A.I. due to his shy and timid behavior infront of the other Freelancers, yet shows the eagerness and desire to please, as most children would display infront of an older sibling. Theta also has the voice of a child.
 * Theta appeared to view other A.I. as his siblings, and stated that he had a sister.
