• A purely mechanical race, made of self-replicating material. Generally choose to appear in arachnid or insectoid shapes. (Nemesis, Small Victories, Enemies)
• They can spray acid in defense/attack -- powerful enough to kill humans (Small Victories) or break through acid-resistant glass (The Menace)
• Originally created as "toys" by a lonely, scared, childlike robot named Reese. (The Menace)
  • She was made of self-repairing nanobots, and used those to form her "toys". (The Menace)
    • Her nanobots deactivated when separated from her body, but she seems to have been able to overcome that in making her toys, which were themselves self-repairing/replicating. (The Menace)
    • She could take any piece of metal, and, using her nanobots, reshape it into whatever she wanted, including the building blocks of her "toys". (The Menace)
  • The people on her planet were scared of her and what she could do, and wanted to destroy her and her toys. She taught them to defend themselves (and her). (The Menace)
  • Reese's toys escaped her control and defended themselves right into the entire destruction of that planet, leaving her the only survivor. (The Menace)
  • After everyone was dead, the "toys" left, leaving her alone, so she went to sleep. (The Menace)
  • SG-1 found her, brought back to the SGC, and woke her up. (The Menace)
    • She was held on Level 21, between doors M-4 and M-6 (interior numbers on the exterior door, the M-4 door says M-5).
    • She told them she was was "asleep" to avoid the danger, and was waiting for her "father" to wake her up and tell her everything was okay. (The Menace)
    • She got bored again and started making "toys" once more, reverting right back to the (rather paranoid) pattern of feeling like she was under attack and using the toys as her defenders. (The Menace)
• At least some Replicators managed to escape their original planet and make it to the Asgard galaxy, although it's not clear how. There were no active Replicators left on the planet when SG-1 came across it, just a few of the building-blocks. (The Menace)
• Their odds of surviving in a new environment depend on numbers. (Nemesis)
• They ingest metal, preferring the highest-tech equipment available. Energy blasts won't stop them, unless it's a blast strong enough to annihilate anything. (Nemesis, Small Victories)
• Replicators can function individually, but all have the same goals: to survive and replicate. (Nemesis)
• Intelligent, capable of learning and adapting. No apparent interest in communicating with any other races.
• If they land on a planet, they'll eat everything in sight.
• Projectile weapons can stop them, but not easily, and not completely -- Replicators can reform out of just a few shards. (Small Victories)
• Attracted to the high-energy output of the Asgard transport beam, and if on an Asgard ship, are drawn toward the spot where something/someone gets beamed in. (Nemesis)
• Neutronium is essential for the creation of human-form Replicators. (New Order)

• The Asgard found them on an abandoned planet and brought them aboard a ship to study, realizing too late what they had done. The Replicators learned everything they could about the technology on the ship then began conquering the Asgards's galaxy -- not to rule, just to self-replicate. They have no other purpose. (Nemesis)
• The first thing the Replicators do on an Asgard ship is disable the sensors capable of detecting them. (Nemesis)
• During a battle, they infested the Biliskner and began taking it over, despite Thor's best efforts. When they got into the computer, they found out about Earth, and headed the ship for it. (Nemesis)
  • On the Biliskner over Earth, the Replicators were going to ingest as much of the ship as possible without risking the hull's integrity, then land and go in search of more resources, according to Thor. (Nemesis)
• They were on the verge of winning the war against the Asgard, which would leave them free to finish devouring everything in that galaxy and move on to ours, when the Asgard baited a trap for them, using the android Reese to call them all to the Asgard homeworld, Hala, where the Replicators were supposed to be caught by a time dilation device. (Unnatural Selection)
  • The Replicators figured out what the device was, and also figured out who and what Reese was. They decided that the next step in their evolution was to become more like their creator -- aspects of her technology were superior to their own -- and developed a cellular creature (rather than one made of relatively large blocks -- basically, they evolved into nanites) that took the form of a human. Presumably, having cell-level control over their forms allows the new Replicators to control such things as their density, allowing them to penetrate practically anything that's permeable in any way. (Unnatural Selection)
    • The flaw in Reese's emulation program was discovered during First's creation. They attempted to repair the flaw during Fifth's creation, but the Replicators disapproved of the result, considering Fifth to be far too weak. No other humanoid Replicators will be made with that flaw repaired. (Unnatural Selection)
    • The first of these celled creatures slid through a microscopic crack in the time dilation device's neutronium shell, and stopped it before it could activate. Later, the Replicators turned it on -- in reverse, speeding local time up by a factor of 10 squared (meaning that during one normal hour, four days pass in local time -- during one 24-hour day outside the bubble, 96 days pass in local time inside it). (Unnatural Selection)
  • Once they'd reversed the machine, the Replicators took full advantage and ate Hala bare, until there was nothing left for most of them to do but line the surface of the planet, covered in drifting dust. Some remained aloft in ships, guarding the planet while more humanoid Replicators were created. (Unnatural Selection)
  • When SG-1 arrived at the Asgards's behest to try to fix things, the Replicators chose to capture, rather than kill, them. They wanted to poke around inside the team's minds to discover everything they knew, including information about the SGC. (Unnatural Selection)
  • Leaving SG-1 alive was a mistake. Sam convinced Fifth to help them, and they reset the time dilator to its original function, trapping the Replicators on the planet in an extremely slowed time-bubble, so that a few days to them would be hundreds of years to the rest of the universe. Any Replicators in orbit who escaped before the time dilation field hit them were hunted down by the Asgard, although there's no final tally on whether they were all caught. (Unnatural Selection)
• It took less than two years of realtime for the trapped humanoid Replicators to reach and begin modifying the time dilation device. (New Order)
• Despite being on a planet that was breaking up as a result of a sudden black hole in the neighborhood (courtesy the Asgard, who had collapsed Hala's sun for that very purpose), enough Replicators managed to get together to form a ship and begin an escape attempt. It worked. (New Order)
• They may have been using the time dilation device to somehow counteract the gravitational forces. (New Order)
• They attacked the Daniel Jackson with a Replicator-missile of sorts -- it breached the ship's hull and the Replicators scattered around, gaining access to the computer before Teal'c started shooting. They discovered the location of Orilla, the new Asgard homeworld, and passed the information along. The Replicator ship, after kidnapping Sam, took off for Orilla. (New Order)
• The ship was destroyed above Orilla by Asgard ships lying in wait, but Fifth managed to escape with Sam, and many Replicator blocks survived entry to rain down on the planet's surface, where they began replicating. They infested many of the systems on the planet, including those that were designed to house Asgard consciousnesses while they awaited new clone bodies. Without those, any Asgard death would be a true death. (New Order)
• Before they could destroy the planet, Thor used a new weapon designed to disrupt  the communication between replicator cells, rendering each one inert. He modified the hand weapon Jack had designed into a giant ship-based weapon that could send a blastwave across the planet's surface, disintegrating all the Replicators there.(New Order)
• A few escaped, in the form of a ship controlled by Fifth. His "brethren" had collected enough neutronium while on the surface to create at least one more humanoid Replicator, which Fifth created in the form of Sam. (New Order)

• Oddly, given that the creator they were basing themselves on was a black female, they were white, and both male and female, and their First was a male (where did they find a male template to use?) (Unnatural Selection)
• Made up of millions of microscopic cell units organisms -- nanites. (Unnatural Selection)
• At least six exist: First, Second, Third, Fourth, Fifth, Sixth (they're not much for original names). (Unnatural Selection)
  • Odd-numbered ones are male in form, even-numbered are female. (Unnatural Selection)
  • Fifth is the most "human" of the lot -- the others consider him deeply flawed. (Unnatural Selection)
• Can communicate via speech. (Unnatural Selection)
• They have some connection to insectoid Replicators at all times, but have to "merge" with them (we don't see how this happens) to communicate complex things, apparently. (Unnatural Selection)
• Are capable of entering a human subconscious by sticking their hands inside people's heads (which apparently gives the nanites the Replicators are made up of a chance to mesh with human neurons enough to see what's going on in there). (Unnatural Selection)
  • After seeing inside several human minds, the humanoid Replicators were convinced that their species was far superior -- they likened it to a human seeing inside the mind of an animal used for food. (Unnatural Selection)
• Are capable of being amused, of understanding at least the concepts of humor and pain. (Unnatural Selection)
• Not restricted to their precise humanoid form -- Fifth had no apparent problem extending his hand out to have much longer fingers to stick them into Sam's head when she was trying to hold his hand away from her, and also seemed to be able to walk though walls (made of Replicator blocks). (New Order)
• The Replicators created more than the six that SG-1 originally met, but it's unclear how many more. (At least one, male form, white.)   (New Order)

• Male form. (Unnatural Selection)
• Has an urbane manner about him -- god only knows where he picked it up from. He has the ability to be amused, and to understand at least the concept of emotional pain -- he uses the memory of Charlie's death, and Jack's guilt about it, to control Jack. (Unnatural Selection)

• Male form. (Unnatural Selection)
• Most "human" of the humanoid Replicators -- the others consider him deeply flawed. (Unnatural Selection)
• He was the first to greet SG-1, and he was the one to bring them from the structure on Hala back to the X-303 to recover a bit.
• He didn't enter any of their minds originally. When First went in after SG-1 recovered and Fifth objected to them being used like that again, First insisted he go in to see "the disorder, the chaos", to compare himself to humans to see his own superiority. Fifth agreed, and took Sam's cue to go into her mind -- but instead brought her into his subconscious, in a small space where the other Replicators couldn't share his thoughts. (Unnatural Selection)
  • Sam convinced him that he was more human than Replicator, and that the Asgard device was only meant to give the Asgard and humans a chance to solve the Replicators's programming flaw. She (sincerely) promised to take him with them if he helped SG-1 escape he believed her. (Unnatural Selection)
  • While Sam and the others were unconscious again from having Replicators in their brains, he reprogrammed the time dilator, back to the Asgards's original plan. He was utterly confused when SG-1 left without him (on Jack's order), leaving him to face First and the others alone. (Unnatural Selection)
• Survived the destruction of Hala and escaped with many non-humanoid Replicators, which grouped themselves into a ship. (New Order)
• After a projectile made of Replicators breached the Daniel Jackson, with Replicators surviving to gather information about the ship, Fifth beamed Sam off and onto the Replicator ship. (New Order)
• He was incredibly angry and hurt at being abandoned on Hala after Sam had promised to help him escape. (New Order, Unnatural Selection)
• He stuck his hand in her head and started pulling out bad memories -- a snarling Unas, Jack in pain (possibly from Lost City, going into stasis), Daniel burning up (from Fire and Water), and piles of skulls in the first round, followed by more burning/flames, more skulls, Apophis forcing her to drink the Blood of Sokar, repeated spider imagery, Teal'c being hit with a torture stick, and a window [no clue what the window means] -- specifically to torment her, so that she would suffer like he had. (New Order)
• He told her that thanks to her (and SG-1's) actions on Hala in trapping him, he learned cruelty, betrayal, and revenge -- like a real human (and unlike all the other Replicators). (New Order)
• After Sam tried very hard to appeal to his better side, he changed tack -- he imprisoned her body and put her mind into a mental utopia of sorts, living on a farm in Montana with Pete Shanahan. (New Order)
• "Pete" told her they'd been there for a year, since she left the stargate program because of mental stress. He said she was having trouble shaking the memories from the program, enough that she was seeing a shrink for it regularly, and that her lack of belief in the reality of the farm when she woke up was just a sign that she was having another episode. (New Order)
• When she steadfastly refused to believe in the "reality", Fifth relented and appeared in Pete's place, saying he'd done all this because he loved her. (New Order)
• Sam was impressed that he had feelings, but shot him down, telling him she'd never be happy in his fake "reality". He turned very cold, promising that she'd be unhappy for a very long time, instead. (New Order)
• Can move through solid walls made of Replicators (because of his cellular-level control of his form). (New Order)
• He was wearing a leather-looking strap as a bracelet, for some reason. (New Order)
• All the while he was alternately torturing and trying to seduce Sam, he was directing the Replicators' infestation of Orilla, making them far more organized than the Asgard had ever seen before. (New Order)
• When Jack, Daniel, and Teal'c beamed down to the planet to rescue Sam, and took on a whole lot of Replicators (Daniel and Teal'c using P-90s, Jack using the weapon he'd created with Ancient knowledge to turn the Replicators into little inert piles of metal scraps), Fifth went out to demand they stop, promising to kill Sam if they attacked him or his brethren any more. (New Order)
• He went back into Sam's mental world to tell her they would have to leave, because thanks to Jack the Asgard had a means of fighting the Replicators. He was going to have to leave many Replicators behind in the city to be killed, because there was no time to wait for them. He told her her friends didn't care about her, because they were still killing Replicators after his ultimatum, and was not happy to find out that she believed that SG-1 knew she'd rather be dead than spend eternity with Fifth. He was in tears when she asked him to either kill her or let her go. (New Order)
• Fifth left in his ship -- a giant spider-Replicator form, made out of "living" Replicators -- but did leave Sam behind to be found by SG-1. (New Order)
• Having collected enough neutronium on Orilla, he created a new humanoid Replicator, identical to Sam. He told her that he would teach her everything he knew, and that while they would have to search for a planet for their brethren to propagate, everyone would soon know that together, the two of them could not be stopped. (New Order)
