Ava Dixon (Replicator)

Ava Dixon was a Tau'ri-built replicator, one of two models of Dr. Richard Poole, as part of the Project Archetype. She had no self-replication as a function and she was also immune to the effects of Anti-Replicator gun technology. She was programmed for social interaction. She knew if she was a replicator.

She was a copy of the real Ava Dixon who died in a car accident during the 2007, Poole programmed her with them memories that he gave her. In 2008 so she worked with Richard Poole to produce an Replicator, but one day she received orders to destroy all evidence and their research by Henry Wallace had been arrested.

A few months before she made contact with John Sheppard and Ronon Dex she had been checking on them at the time when Wallace abduct Jean Miller and Meredith Rodney McKay. And so when the other Replicator managed to escape from them when Poole tried to turn him. She is working with Poole to try to track Replicator but had no luck. She brought in contact with John Sheppard and Ronon Dex who was on the Earth and told us everything about the Project Archetype and the runaway Replicator. She worked with Sheppard to track Poole's Replicator by Bill Lee. They found him and had almost caught him only until he masked his energy signature.

After Lee managed to crack the Poole's computer code, he found information about Ava that she died a few months earlier and the other was a Replicator. She found out about it then by Sheppard. After they found Replicator so intervened Ava to stop him and she gave Sheppard a chance to attach a tracking transmitter on Replicator and beamed him into orbit. She knew she could not be released because she was a Replicator, and she was a security risk. Bill Lee transferred her entire consciousness to a virtual reality pod at Stargate Command where she could explore her world of illusion, how she wanted. While her nanite body had "scrapped" by then melted down and used for anything else.
