The Search for Poole's Replicator was an event that took place in 2008.
Prelude[]
Sheppard heard that his father Patrick Sheppard died of a heart attack, and came to attend his wake with the support of his friend, Ronon. Rodney had confessed he wanted to go, but was unable to. It was there that he learned that his father regretted the argument they once had that drove them apart. He also coerced his ex-wife, Nancy Sheppard into helping find information on Project Archetype to track down a Replicator loose on Earth.[3]
Battle[]
As part of a government project called Project Archetype, Dr. Richard Poole creates two Human-form Replicators, one that he programs to be able to interact socially which he models after a woman that used to work for him named Ava Dixon and acts as his assistant and a military model that isn't given a name. After the kidnapping of Dr. Rodney McKay and the International Oversight Advisory's investigation into Devlin Medical Technologies, Poole tries to shut down the military model Replicator but it kills two guards and escapes. Ava, realizing that he needs to be stopped, approaches Lt. Colonel John Sheppard and Ronon Dex at Sheppard's father's funeral for help in tracking down and stopping the Replicator. They capture Poole and beam him to the Apollo to help but he refuses so with Ava's help they devise a way of tracking the Replicator with the Apollo's sensors and set Dr. Bill Lee at cracking the encryption on the files from Poole's lab. Sheppard manages to get Poole to agree to help by threatening Ava and he reveals that while Anti-Replicator guns won't work on the Replicator, he has a limited self-repair ability so enough firepower would be able to kill him.
When Poole and Agent Bates find the Replicator, Poole knocks Bates out and tries to convince the Replicator to shut down, but it refuses and kills him. It also kills one marine and injures another before escaping, but not before being damaged by Sheppard and Ronon. Sheppard turns to his ex-wife Nancy Sheppard for help in finding anything on Project Archetype but she refuses and the Replicator manages to hide himself from the Apollo's sensors. Lee cracks the encryption and they learn the truth about Ava who runs when she realizes that that was going to happen and also hides herself from detection. Nancy changes her mind and gives Sheppard everything she can find on Archetype which leads them to finding a warehouse that holds Neutronium which the Replicator needs to repair itself. They set a trap there and in the fight that follows, Ava returns to help fight. Sheppard manages to stab a switchblade knife equipped with a locator beacon on it into the Replicator allowing the Apollo to beam him into low Earth orbit causing him to burn up in the atmosphere, destroying him.[3]
Aftermath[]
Later Ava's mind is downloaded into a virtual reality while her body is destroyed as she was too much of a security risk.[3]
