"Replicators exist merely to increase their numbers and do so without prejudice. They are no more evil that a virus"
- Teal'c - Unnatural Selection

The Replicators were a mechanical race.


Human form


Replicators are composed of numerous blocks, that have 2 million isolated Kiron pathways and exert a reactive modulating monopolar energy field on other blocks that allow them to assemble into a variety of forms. The blocks can be made from a number of different materials including Steel and depending on the material, they blocks can have a different color. Several blocks can work together to create more blocks. (SG1: "Small Victories") Replicators can form a human-like shape if needed. (Stargate: The Ark of Truth)

In flesh


They have a high capacity for learning and are attracted to technology and energy discharges. They are impervious to energy weapons fire such as that from a Staff weapon or a Zat'nik'tel, with even three shots having no effect on them. (SG1: "Nemesis", "Enemies") Replicators do not require rest. (SG1: "Small Victories") They can spray a corrosive liquid to help break down materials or to incapacitate targets. (SG1: "Nemesis", "Small Victories") They are capable of altering technology beyond what it was. (SG1: "Small Victories") They can link together to form a sort of generator in order to provide excess energy to other technology. (SG1: "Enemies") They can communicate with one another through subspace. (SG1: "Unnatural Selection") They are capable of embedding themselves into the flesh of other beings and take control of them. (Stargate: The Ark of Truth)



Each Replicator is capable of individual behavior but all work for the common goal of self-replication. They will feed off a variety of materials in order to make more of themselves as their odds of survival is based on numbers. They will not attack unless threatened but will take measure to protect themselves by gaining control of environments they enter, such as disabling sensors that can detect them. (SG1: "Nemesis") Time is not a factor in their operations, travelling a slower speeds on ships to direct more energy to replication. (SG1: "Small Victories")


Several blocks can work together to make more of themselves and single Replicator can turn itself into a "mother" or "queen" and form new blocks to make more Replicators, using whatever material is at their disposal. (SG1: "Small Victories", Stargate: The Ark of Truth)


The Replicators were created by the android Reese on a planet in the Milky Way, who made them as toys for her to play with. When others grew fearful of her and the Replicators she taught them to make more of themselves and defend her. She eventually lost control of them and they killed everyone and then left the planet. (SG1: "Menace") The Asgard discovered the Replicators on an isolated planet in their galaxy and brought several of them aboard for study only for them to escape and begin replicating. The Replicators targeted the advanced technology of the Asgard and the two were at war. When in battle, the Replicators took over the Biliskner and took it to Earth, having found information on it in the ships computer. SG-1 came aboard and helped destroy the ship to stop them from infesting Earth. Unfortunately a single Replicator survived the crash. (SG1: "Nemesis") The Replicator took over the Russian submarine Blackbird and killed the crew, using the raw materials of the submarine to make more Replicators. The original Replicator was take out and the submarine and the rest of the Replicators were destroyed. Several Replicator-controlled Asgard ships made their way to Othala and destroyed other ships that came to stop them. The O'Neill was launched to draw them away, attracting them to the advanced technology of the ship, and it's auto-destruct was used to take out the Replicator ships. (SG1: "Small Victories")

Providing power

The Replicators spread to another galaxy and encountered another technology there. They took control of Apophis' Mothership and Cronus' Ha'tak that arrived in the galaxy, using the former to try to get to Delmak in the Milky Way to access the resources there, but they were destroyed once they had arrived. (SG1: "Enemies") When Reese was found by Stargate Command and reactivated, she made more Replicators which she used to take control of the base in order to escape. At least one Replicator broke free of her control but was destroyed. She was convinced to shut them down which she did after being shot, before she died. (SG1: "Menace") The Asgard took Reese's body and learned something which allowed them to begin to win battles against the Replicators. (SG1: "Revelations") The Replicators were drawn to Hala where they were going to be trapped within a Time dilation field and they found the body of Reese which they used as a template to create the Human-form Replicators. The Replicators used the time dilation device to accelerate time and then consumed all the resources on Hala, multiplying many times and ending up covering the planet in Replicator blocks, dormant to conserve energy. They were trapped on the planet when the time dilation device was activated correctly. (SG1: "Unnatural Selection")

When Hala was destroyed some of the Replicators, controlled by Fifth, survived and formed a ship that they took to Orilla, the new Asgard homeworld. (SG1: "New Order, Part 1") The ship was destroyed in orbit but Replicator blocks rained down on the planet and they began replicating and infesting. When a weapon was developed that could destroy them, they formed another ship and fled. (SG1: "New Order, Part 2") Replicator Carter gained control of the Replicators after she destroyed Fifth and spread to them the cypher that allowed them to resist the weapon created to destroy them. (SG1: "Gemini") The Replicators began attacking Goa'uld forces, easly defeating them and headed for Dakara, where a weapon had been found that could destroy them. The weapon was activated, translating through the Stargate to every world and destroyed the Replicators. (SG1: "Reckoning, Part 1", "Reckoning, Part 2") James Marrick was given a Control crystal to insert into the Asgard Computer core to instruct it to make a Replicator, intending to use them to destroy the Ori fleet. These Replicators were immune to the Anti-Replicator gun but had a shut down built into them. The Replicators began taking over the Odyssey including embedding themselves into Marrick and taking control of his body. The shut down code was used on them. (Stargate: The Ark of Truth)
