Theta was an A.I. construct designed for the Special Operations program Freelancer, originally assigned to Freelancer North Dakota. He was able to run North Dakota's enhanced motion tracker, and, by extension, his Domed Energy Shield. As Recovery Command was aware that North still had possession of Theta, it can be assumed that Theta was similar to the Delta A.I., in that it was not deemed dangerous and removing it from North was not necessary. Theta was stolen by the Meta when he murdered North, and was later destroyed by the EMP Washington set off in Reconstruction. However he still exists as a memory in Epsilon, as seen in Long Time No See. Theta is a fragment of the Alpha A.I., specifically the Alpha's trust.
