Replicator (Stargate) - Human-form Replicators

Human-form Replicators

In the Stargate SG-1 episode "Unnatural Selection", SG-1 encounters the human-form Replicators on the former Asgard world of Halla, who capture them and probe their minds to learn about Earth and the SGC. The human-form Replicators are claytronic in nature, derived from the technology of the android Reese's self-repair nanites. They are physically indistinguishable from humans and possess immense strength and resilience, lacking the traditional Replicators' vulnerability to firearms. They are capable of interfacing with the mind of a human by extending their hand into the victim's forehead. Human-form Replicators can restructure parts of themselves to form implements such as stabbing weapons, or disconnect portions from the whole. Neutronium is a crucial element in the construction of human-form Replicators. The original human-form Replicators depicted in "Unnatural Selection" are, in order of their creation:

• First, their leader, played by Ian Buchanan.
• Second, played by Kristina Copeland.
• Third, played by Tahmoh Penikett.
• Fourth, played by Rebecca Robbins.
• Fifth, played by Patrick Currie.
• Sixth, played by Shannon Powell.

At the end of "Unnatural Selection", all the human-form Replicators are trapped on Halla after SG-1 activates the time-dilation device. The only one of the original six Replicators who appears in subsequent episodes is Fifth, who escapes Halla in "New Order".

Another human-form Replicator also appears in "New Order", Eighth. He was played by James Bamford, the stunt-coordinator of Stargate Atlantis, which was shooting its pilot during "New Order"; the producers wanted to make Bamford feel as part of the family. Eighth is recovered, damaged and inactive, by Thor, as a means to tap into the Replicator network and determine the location of Fifth. Eighth activates and breaks free aboard Thor's ship, and is disintegrated by Jack O'Neill using the newly constructed Replicator Disruptor.
