Eighth

Eighth was a human-form Replicator discovered in orbit around Orilla after the Asgard had destroyed an approaching Replicator vessel commanded by Fifth.

Eighth, who was heavily damaged and inoperable at the time, was brought on board by Thor, who attempted to access the datastream that linked all Replicators together in order to learn more about the Replicators down on the surface of Orilla. However, the attempt led Fifth to revive Eighth, who subsequently attempted to kill everyone on board. Eighth was killed by Jack O'Neill, using the newly constructed Replicator Disruptor, testing the device in the process.
