Artificial human characters in Stargate

This is a list of prominent artificial human characters in the fictional universe, including human-form Replicators encountered by SG-1, and Asuran characters thus far encountered by the Atlantis Expedition. Replicators are a race of self-replicating machines. The Asurans are a race in the Stargate Atlantis that bear many similarities to the Replicator of Stargate SG-1.

Android SG-1

They first appear in the episode "Tin Man", and then appear again in the episode "Double Jeopardy"

Miscellaneous characters

Harlan

Template:Stargate character Harlan the last android survivor of Altair. He was called annoying by Jack O'Neill, and was fond of saying com'traya, an Altair greeting of some sorts.

Harlan maintained the factories beneath the surface for over 11,000 years, as the facility is essential for the survival of his android form. After the surface of the planet became uninhabitable due to an unidentified environmental disaster, Harlan and many like him downloaded their consciousnesses into mechanical android bodies, allowing them to live indefinitely, as long as their power supply is not depleted. This power supply is usually maintained by a projected field of energy, however, beyond that field, he and his race rely on battery cells with a limited power supply.

However, over time, most inhabitants became disgruntled with their meaningless life, and several survivors committed suicide by intentionally allowing their power packs to run out. Others, died in accidents. After a survivor named Wallas died, Harlan remained on his own, forced to maintain the complex alone.

When SG-1 arrived millennia later, Harlan rendered the team unconscious and, unknown to them, created mechanical copies of the four. These copies were initially unaware of their true nature, and tried to return to Earth. However, after discovering their true identity, these four androids had no other choice then to remain on Altair with Harlan, and aiding him in maintaining the plant. But, like their original selves, they eventually couldn't bear their isolation after burying the Stargate and, against Harlan's advice, began exploring the galaxy.

After these copies of SG-1 had been captured by Cronus, Harlan went to Earth to ask for help. The real SG-1 reluctantly agreed, but after the duplicate SG-1's death (Robo-Daniel had his head shot off, Robo-Sam gave her life to disable a security shield keeping her, Sam and Jack trapped, Robo-Jack was badly damaged in their attempts to secure the ring transporters and Robo-Teal'c died after saving Teal'c from Cronus), Harlan eventually returned to Altair without his four companions. It is unknown whether or not he recreated them.

Reese

Template:Stargate character Reese has her first and only appearance in the Season 5 episode "Menace" but is mentioned several times later. She is a significant character in the Replicator stories in the Stargate universe.

Reese is an advanced gynoid possessing an internal power cell. Reese was developed for unknown purposes on her homeworld by a scientist whom Reese considered her "father". Reese provides a very realistic illusion of humanity, and even has a pulse. Her systems are maintained by millions of nanites, designed and programmed to work together as a self-repair mechanism. These microscopic machines deactivate when disconnected from the android's body, but the nanobots used for self-repair are also able to reorder matter on a microscopic level, enabling her to create a variety of objects from raw material. The civilization on Reese's world became afraid of Reese when she developed mechanical toys to counteract her boredom. They eventually tried to destroy her, but Reese programmed her toys to make more of themselves and defend her and one another. Eventually, the toys destroyed her father and the rest of the civilization, then left her alone on the planet.

The personality contained within the android is flawed, and Daniel and Carter label Reese emotionally immature. Reese builds a Replicator as a present for Daniel that causes a critical Replicator situation in the SGC, but Daniel convinces Reese to deactivate the replicators, however O'Neill shoots Reese soon after thinking the replicators were still active. Reese's remains were given to the Asgard, who subsequently studied her. When Freyr visited the SGC, he revealed that they finally gained the upper hand in their battle against the Replicators. They later found a command inside Reese ("to come forth"), which allowed the Asgard to create a trap which captured all Replicators in the known universe in a time dilation field. However, the short encounter between the Replicators and their original creator eventually enabled them to develop nanite-based human-form Replicators.

Replicator characters

First

Template:Stargate character First was a male human-form Replicator, and was the first ever created by the replicators created by Reese. First considered himself and his kind to be superior to non-Replicators, and firmly believed it was his species' right to rule the universe. His programming was based on the corrupted programming from the android Reese.

After the android Reese, who had created the first generation of Replicators many centuries ago, was discovered and eventually killed by SG-1, her remains were given to the Asgard. The Asgard used the body to lure every Replicator in the known universe to Halla, an abandoned Asgard planet. After the Replicators came in contact with Reese, they hailed her as their creator, and found her nanite cells contained advantages that the standard Replicator blocks lacked. Using the nanites in Reese's self-repair mechanism, they were able to create the nanite-based First.

It was the Asgard's intention to trap the Replicators in a massive time-dilation field, but when the time-dilation device was supposed to activate, First could penetrate a minuscule crack in the neutronium shell protecting the time-dilation device. He subsequently stopped and even reversed the device, allowing his brethren to completely consume Halla's civilization within what appeared only days to the outside universe. Several other human-form Replicators were eventually created, including Fifth. However, First treated Fifth as a flawed creation, when in fact Fifth was the only Replicator in existence that was not governed by Reese's flawed programming.

After the Asgard contacted SG-1 to figure out what had happened on Halla and reactivate the time-dilation device, the team was captured after their landing. First probed Jack O'Neill's mind in an attempt to gain intelligence regarding the worlds the team had visited in the Milky Way. He forced O'Neill to cooperate by making him relive his worst memory, the memory of his son accidentally shooting himself, every time O'Neill refused.

Eventually, after Fifth reactivated the time-dilation device, First was trapped on Halla along with the rest of his species. It is believed First was destroyed when Halla's star was converted in a black hole by the Asgard in an attempt to destroy the Replicator threat once and for all.

Second

Template:Stargate character Second was a female human-form Replicator, and was apparently the second to be formed on Halla after the discovery of Reese.

Second firmly believed in the inferiority of non-Replicators, and was one of the first four who got the chance to enter the minds of SG-1 to gain intelligence about the planets the team had explored in the Milky Way. She was later trapped on Halla after SG-1 was able to activate the time-dilation field.

Second was probably killed when Halla's star was converted into a black hole by the Asgard in an attempt to destroy the Replicator threat once and for all.

Third

Template:Stargate character Third was a male human-form Replicator, and was apparently the third to be formed on Halla after the discovery of Reese.

Third was one of the first four who got the chance to enter the minds of SG-1 to gain intelligence about the planets the team had explored in the Milky Way. He was later trapped on Halla after SG-1 was able to activate the time-dilation field.

Third was probably killed when Halla's star was converted into a black hole by the Asgard in an attempt to destroy the Replicator threat once and for all.

Fourth

Template:Stargate character Fourth was a female human-form Replicator, and was apparently the fourth to be formed on Halla after the discovery of Reese.

Fourth was one of the first four who got the chance to enter the minds of SG-1 to gain intelligence about the planets the team had explored in the Milky Way. She was later trapped on Halla after SG-1 was able to activate the time-dilation field.

Fourth was probably killed when Halla's star was converted into a black hole by the Asgard in an attempt to destroy the Replicator threat once and for all.

Fifth

Fifth is a fictional 'human-form' Replicator in the television show Stargate SG-1, played by Patrick Currie. For a time, he was the leader of his race.

Like other human-form Replicators, and standard Replicators for that matter, Fifth was constructed from the conjoinment of a large number of identical Replicator "blocks". Human-form Replicators, as their name suggests, take perfect human form, and are composed of much smaller blocks (i.e. nanites) than standard Replicators.

Fifth is extremely strong, agile, and wears a grey outfit. He is invulnerable to both projectile and energy weaponry, and is connected to the Replicator datastream called "The Link". In addition, he can also probe the mind of humans by inserting his hand into the victim's forehead, as he demonstrated on Samantha Carter on several occasions.

He was the only Replicator in the human-form series in which the programming flaw discovered in the android Reese, the original creator of the Replicators, was corrected. As such, Fifth possesses a human psyche, including genuine human emotions, which make him more human, but also more fallible and, in the eyes of his fellow Replicators, weak.

After the android Reese, who had created the first post-Asuran generation of Replicators many centuries ago, was discovered and eventually killed by SG-1 , her remains were given to the Asgard, who used the body to lure every Replicator in the known universe to Halla, an abandoned Asgard planet. After the Replicators came in contact with Reese, they hailed her as their creator, and found her nanite cells contained advantages that the standard Replicator blocks lacked. Using the nanites in Reese's self-repair mechanism, they were able to create the first human-form Replicator, First.

It was the Asgard's intention to trap the Replicators in a massive time-dilation field, but when the time-dilation device was supposed to activate, First could penetrate a minuscule crack in the neutronium shell protecting the time-dilation device. He subsequently stopped and even reversed the device, allowing his brethren to completely consume Halla's civilization within what appeared only days to the outside universe. Eventually, several other human-form Replicators were created on Halla, including Fifth.

Fifth was the first attempt at reproducing her emotions, however, he was considered a failure by the first four human-forms before him, who considered him weak. The Replicators formed a family unit of sorts, although this "family" lacked any human warmth and existed only to lead the immense army of Replicators.

After the Asgard contacted SG-1 to figure out what had happened on Halla and reactivate the time-dilation device, the team was captured after their landing. Fifth developed an interest in Samantha Carter, and because of his feelings for her agreed to help the team reactivate the time-dilation field, essentially trapping his comrades. However Jack O'Neill didn't trust Fifth and ordered Major Carter to set the time for the trap to be acivated shorter than planned. Although Carter was reluctant about this, she did as ordered and Fifth discovered that he was betrayed shortly before the field reactivated. He realized that SG-1 had used his own humanity against him.

After two years passed in real time, the Asgard had collapsed Halla's sun into a black hole, which would eventually destroy the planet. However, before Halla passed the event horizon, some Replicators, led by Fifth, were able to escape the planet using the time-dilation device to counteract the black hole's gravity. As the rest of his species was destroyed, Fifth became the leader of the Replicators and commanded the ship to attack the Asgard's new homeworld, Orilla.

However, Fifth still resented Carter for betraying him on Halla, and was bent on taking revenge. At the time, Carter was seeking the assistance of the Asgard to help Colonel Jack O'Neill after his encounter with the Ancient Repository of Knowledge, and was near Halla during Fifth's escape. Fifth attacked the Asgard ship she was on and kidnapped Major Carter, using his telepathic powers to torture her and play with her mind en route to Orilla. As he tortured her, Carter said that being human was having the power to forgive, with Fifth coldly replying that he wasn't there yet. However, once he saw how much pain Carter was in, he relented.

However, when his ship arrived at the Asgard planet, it was destroyed by several O'Neill class battleships. Fifth was able to escape the destruction of his ship along with Carter and created a base on the planet, although Carter could eventually convince him to let go of his hatred and release her. After O'Neill had used the Ancient knowledge still in his mind to create an effective weapon to be used against the Replicators, the so-called Replicator Disruptor, Fifth was forced to abandon the planet. However, Fifth subsequently created another human-form Replicator which resembled Carter, who even had her memories, to be his consort.

Because of the recently discovered Replicator Disruptor, the Replicators' quest to control the Galaxy had reached a dead end. In the meantime, the human-form Replicator created in the image of Samantha Carter, also known as "RepliCarter", who, like the real Samantha Carter did not share equivalent feelings for Fifth, was able to fool Fifth into believing that she was loyal to him, and maybe even shared his love. The two eventually devised a plan to discover how to immunise their race from the Replicator Disruptor.

The plan involved sending RepliCarter to the SGC, claiming that she had betrayed and fled Fifth, and expressing a wish to be destroyed by their Disruptor. Believing her, SG-1 took her to the Alpha Site to question her, where she informed them (untruthfully) that Fifth had immunised every single Replicator to the Disruptor, except her due to his spite. However, she promised to help them realign the Disruptor to overcome Fifth's immunisation. As they began work on the Disruptor, RepliCarter was able to study the weapon to discover how to immunise her race from it, and relayed reports of her progress back to Fifth. Unbeknown to the SGC and SG-1, Fifth was tracking her position, on his way to attack the planet, confident RepliCarter would upload the cipher to render the Disruptor useless before he arrived.

However, RepliCarter eventually betrayed Fifth by firing the Replicator Disruptor at his ship before she uploaded the cipher. Both he and his ship were destroyed, before RepliCarter immunised herself and her race. Fifth was succeeded by RepliCarter, who became the leader of the entire Replicator race.

Sixth

Template:Stargate character Sixth was a female human-form Replicator, and was apparently the sixth to be formed on Halla after the discovery of Reese.

She was the only one who didn't get the chance to probe the minds of SG-1, and became later trapped on Halla after SG-1 was able to activate the time-dilation field.

Sixth was probably killed when Halla's star was converted into a black hole by the Asgard in an attempt to destroy the Replicator threat once and for all.

Eighth

Template:Stargate character 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.

Eighth broke the previously observed pattern, commented on by Colonel O'Neill in "Unnatural Selection", of odd-numbered Replicators being male and even-numbered Replicators being female.

• Eighth was not referenced by name in the episode and was the seventh human-form Replicator encountered by SG-1. His name was revealed to be Eighth in the ending credits of the episode, but what became of the logically-existent 'Seventh' was never revealed.

Replicator Carter

Template:Stargate character In the science fiction television series Stargate SG-1, Replicator Carter, commonly referred to by fans as RepliCarter, is a human-form Replicator created in the image of Samantha Carter, and posed a major threat to life in the Milky Way and other galaxies.

Notably, the only time that Replicator Carter is named on the show is when Daniel Jackson calls her by that name in a descriptive fashion. Because human-form Replicators have traditionally been named by the order of their creation, and as the human-form Replicator destroyed in the same episode was called "Eighth" in the ending credits, her actual name might be "Ninth". A trailer for the upcoming Stargate Online Trading Card Game however, lists her name as Replicator Carter.

Like other human-form Replicators, and standard Replicators for that matter, RepliCarter was constructed from the conjoinment of a large number of identical Replicator "blocks". Human-form Replicators, as their name suggests, take perfect human form, and are composed of much smaller blocks (i.e. nanites) than standard Replicators.

She was made in the real Carter's image, even down to memory and character. This information was probably collected during Carter's imprisonment by Fifth on Orilla. However, the differences between Samantha Carter and RepliCarter have become quite pronounced due to Fifth's training of the latter, making RepliCarter a megalomaniacal, ruthless, dominating conqueror. She also believed that these traits were also within the original Samantha Carter, as "all humans desire power". According to RepliCarter, the only difference between the two is that Samantha never had the bravery, or means, to act upon it.

RepliCarter, like other human-form Replicators, is invulnerable to both projectile and energy weaponry. She possesses the ability to reform herself at any time, not only to heal herself but also to shape her arm into a weapon like a long sword, with which to kill enemies. She can also deactivate portions of herself, effectively enabling her to leave parts of her body behind. RepliCarter is also connected to the Replicator datastream called The Link.

After the android Reese was used as bait by the Asgard to trap all Replicators in the known universe inside a time dilation field, the advanced technology, including the nanites within Reese's systems, were studied by the approaching Replicators. Based upon these nanites, the first human-form Replicator could be constructed. However, Reese's programming was flawed, which was also discovered by the Replicators, who attempted to correct the error in the creation of Fifth.

As a result, Fifth was both the first and the last human-form Replicator created with the capacity for emotion, as the others came to see the feature as a flaw. This led to Fifth falling in love with Samantha Carter, and when he realised he could not have a relationship with her in the form he desired, he created a perfect replica of her intended to accept him.

Fifth intended for RepliCarter to govern the Replicator race with him, and to be his consort. Due to his infatuation with Samantha, he made her exactly in her image, down to her memories and character. However, this in part led to her despising what he was trying to do as much as the original Samantha Carter would have.

After Jack O'Neill had engineered a weapon able to disintegrate any Replicator in its blast-radius (the Replicator Disruptor) based upon Ancient knowledge, the Replicators' quest to control the Galaxy had reached a dead end. In the meantime, RepliCarter was able to fool Fifth into believing that she was loyal to him, and maybe even shared his love. The two eventually devised a plan to discover how to immunise their race from the Replicator Disruptor.

The plan involved sending RepliCarter to the SGC, claiming that she had betrayed and fled Fifth, and expressing a wish to be destroyed by their Disruptor. SG-1 took her to the Alpha Site to question her, where she informed them (untruthfully) that Fifth had immunised every single Replicator to the Disruptor, except her due to his spite. However, she promised to help them realign the Disruptor to overcome Fifth's immunisation.

As they began work on the Disruptor, RepliCarter was able to study the weapon to discover how to immunise her race from it. She relayed reports of her progress back to Fifth, keeping in communication with him via the datastream between all Replicators. Unbeknown to the SGC and SG-1, Fifth was tracking her position, on his way with one of his powerful Replicator ships to attack the planet, confident RepliCarter would upload the cipher to render the Disruptor useless before he arrived.

However, RepliCarter eventually betrayed Fifth by firing the Replicator Disruptor at his ship before she uploaded the cipher. Both he and his ship were destroyed, before RepliCarter immunised herself and her race. Teal'c attempts to stop RepliCarter by grabbing her arm, but the arm is detached from her body and she escapes via the Alpha Site's Stargate. Carter's attempt to violate General O'Neill's orders to terminate RepliCarter is a major factor in her escape. The arm removed by Teal'c decomposed into deactivated cells which are studied by Carter, who felt responsible for her doppelgänger's victory.

RepliCarter subsequently took over Fifth's position and became the leader of the entire Replicator race.

Several months later, Replicator Carter led her army back to the Milky Way, and launched a massive attack on the Goa'uld, taking over their territories and incorporating their technology into her own.

Knowing of the ascended knowledge still present in Daniel Jackson's subconscious mind, information that could possibly be a threat to her invasion, RepliCarter captured her doppelgänger's teammate. After hours of probing his mind, RepliCarter discovered the existence of the Dakara Superweapon, a device that, when altered, could be used to destroy her entire army at once.

However, the Replicator invasion, seen by many Jaffa as holy retribution for their blasphemy against their Gods, proved not only to be disastrous for the Goa'uld, but also caused many rebelling Jaffa to revert to their old religion. Teal'c and Bra'tac, along with many Free Jaffa, subsequently attempted to take over the Temple at Dakara, an act that they believed would prove to all Jaffa that the Goa'uld are not gods.

RepliCarter sent her forces to Dakara to eradicate the weapon, engaging the Jaffa rebels and Ba'al's fleet, who had turned his fleet on Dakara to drive out the Rebel Jaffa. However, Samantha Carter had also discovered the weapon, who recognised it as the only thing capable of destroying the Replicators, being based upon the same technology as the Replicator disruptor.

The Replicators eventually landed on Dakara and attempted to reach the weapon. In the meantime, Daniel, whilst allowing RepliCarter to enter his mind, was able to work his way into her mind, and was able to momentarily freeze every single Replicator in the galaxy, including those on Dakara and those invading the SGC. This gave Samantha Carter enough time to alter the weapon with help from Jacob Carter/Selmak and Ba'al to send out waves that would only cause Replicators to permanently disassemble. This wave was spread over the entire galaxy via every working Stargate, destroying all Replicators in the Milky Way galaxy, including RepliCarter.

Asuran characters

Cetus

Template:Stargate character Cetus was an Asuran and enemy of Dr. Elizabeth Weir and her team.

Cetus was the second-in-command of the attack team sent to capture Atlantis in retribution for the Ancients' betrayal millennia ago. As the handful of Ancients who had recently retaken control over their city were still under the impression that the Asurans were unable to harm their creators, due to a directive that had been deleted from their base programming some time ago, they were unprepared for the invading Asurans. After Cetus and his team had taken control over the city, they killed the surviving Ancients after having probed their minds.

Although the SGC had decided to destroy Atlantis after the city had fallen to the invaders, Dr. Weir disobeyed orders and travelled back to the Pegasus Galaxy accompanied by John Sheppard, Rodney McKay and Carson Beckett in a Puddle Jumper. After having enlisted the help of Ronon Dex and Teyla Emmagan, the Jumper travelled through the Stargate to the fallen city.

Unable to raise the Iris shield, Cetus was present in the Gate Room when the invading Jumper emerged. Although the ship was heavily fired upon, the Jumper escaped by breaching the Gate Room's outer wall, and dropped explosives before departing, heavily damaging the Control Tower. Cetus however was able to escape before the bomb detonated.

As Talus realized that the Jumper had briefly communicated with survivors still hiding in the city, Cetus was sent to search the city for the ones Sheppard came to rescue. After the search parties discovered General Jack O'Neill and Richard Woolsey, the two were captured, and Cetus probed Woolsey's mind for information. He discovered what appeared to be information about Sheppard's plan involving destroying the city's shield emitters.

However, as Rodney McKay had fed Woolsey and O'Neill false information regarding their intentions, the Asurans were unaware that the shield had instead been modified to emit a massive energy burst similar to the wave emitted by an ARG. As Talus ordered Cetus to activate the shield upon the arrival of the Daedalus, he secured his own doom. His body was subsequently disintegrated when the wave reached his position, severing the kiron pathways between his individual cells.

Though he is presumed to be dead, its entirely possible that the subspace link among the Asurans would allow them to replicate him as Oberoth himself was replicated after his destruction around Lantea. However, he is presumably permanently destroyed in Be All My Sins Remember'd when the team destroys the Asurans with help from the Wraith and the Travelers.

Niam

Template:Stargate character Niam was an untraditional Asuran and hesitant ally of Elizabeth Weir and her team.

Niam was known for believing that his people had become stagnant in their evolutionary path. He believed it was his people's destiny to eventually ascend, and finally be able to completely emulate their creators, the Ancients. However, he was convinced that the aggression in the Asuran's programming prevented them from ascending. He therefore had a philosophical disagreement with High Councilor Oberoth, who preferred the status quo. Niam nevertheless remained an adviser to Oberoth and his Council.

Niam was fascinated with the members of the Atlantis expedition who visited Asuras in 2006. When he realized their guests had knowledge about ascension, he expressed interest in learning more from them. However, Oberoth imprisoned the visitors, and after learning of Atlantis' survival decided to destroy it themselves. Niam pleaded for the survival of the captured Weir and Shepperd's team.

However, Niam, along with the few who also believed ascension was the Asurans' future, secretly struck a deal with the captured members of the Atlantis expedition: in exchange for Dr. Rodney McKay removing the base aggression from his people's programming, which they could not do themselves, Niam and his allies would do everything in their power to make Oberoth reconsider destroying Atlantis and help in Earth's fight with the Wraith. He was also the Asuran who informed Weir's team about his people's true nature and history.

Dr. Weir initially agreed, but eventually decided to betray Niam's trust and try to destroy Asuras themselves, ensuring Atlantis' safety. McKay had discovered a way to freeze the Asurans in a feedback loop for a small period of time, but because Niam's programming had been altered, he did not get stuck in this loop as his fellow Asurans were. Dr. Weir convinced him to escape along with her team, and made him even enter the access codes that permitted McKay to overload the three ZPM's powering the city, destroying Asuras just as it entered orbit around Atlantis.

Niam escaped aboard a Puddle Jumper with the Atlantis team, but when the rest of his people became aware of what he had done, his programming was reset, reverting back to his aggressive nature. Niam subsequently tried to strangle Dr. Weir, forcing Sheppard and the others to open the rear hatch of the Jumper, blowing him into space. The few nanites introduced into Weir's bloodstream however became a threat to her life, before they were eventually destroyed by her own immune system and Dr. Carson Beckett's medical care.

After Atlantis was overrun by the Asurans, Niam was retrieved by Sheppard and his team in an attempt to use him to transmit a program that would immobilize the Asurans and allow them to be easily destroyed. However, the ruse was discovered and Niam revived, forcing McKay to destroy him with an Anti-Replicator Gun.

Though he is presumed to be dead, it is entirely possible that the subspace link among the Asurans would allow them to replicate him as Oberoth himself was replicated after his destruction around Lantea. He may have been destroyed in Be All My Sins Remember'd when the team destroys the Asurans, but there is speculation he may have been replicated to form part of the surviving faction which seems to be led by Elizabeth Weir's duplicate.

McKay managed to reactivate the dead nanites with Weir to save her life.

Oberoth

Template:Stargate character Oberoth, played by David Ogden Stiers is High Councilor of Asuras and leader of the Asuran people. Oberoth apparently was the first of the nanite-based machines that took on the form of their creators, the Ancients [in appearance that vaguely resembles Lantean High Counciler Moros]. Like all Asurans, Oberoth was governed by the same base aggression in their programming. This aggression was built into them as the Ancients were hoping to use the nanites as a devastating weapon against the Wraith. Oberoth was a fierce proponent of maintaining the status quo, and was not interested in ascension. This made him an opponent of Niam [similar to the Lantean scientist Janus], although Oberoth frequently relied on Niam's advice, and occasionally approved some of his requests. Oberoth also accuses the Ancients of being arrogant, what in his view led to their defeat by the Wraith. However, Dr. Weir accused him of being at least as arrogant as his Lantean cousins. He was also one of the few Asurans who were not amused by visitors.

When several member of the Atlantis expedition visited Asuras in 2006, Oberoth clearly indicated they were not welcome. When Dr. Weir subsequently asked Oberoth for a number of spare ZPM's, he refused her request. However, he tried to appease her by informing Weir that the eradication of the Wraith was among his people's long-term goals, although it's doubtful he was being honest.

The aggression in his programming eventually led him to take Dr. Weir's team prisoner, and after personally invading the mind of John Sheppard and learning about Atlantis' survival, he decided to destroy the former capital of his creators himself. However, he agreed to keep his prisoners alive, as requested by his aide Niam. This eventually proved to be a mistake, when the Atlantean visitors were able to escape, and, with the help of Niam, freeze the remaining Asurans (including Oberoth) in a feedback loop.

Oberoth eventually retook control of his own programming, and tried to prevent Weir's team from reaching the Puddle Jumper bay. However, Dr. McKay, again with Niam's assistance, had managed to overload Asuras' ZPM's, and the city was subsequently destroyed in orbit around Atlantis.

Oberoth was later revealed to have survived, as his consciousness was preserved in the collective of the Asurans subspace network. After the Apollo launched a massive nuclear attack on Asuras, Oberoth had a satellite carrying a Stargate sent to Lantea, where it launched a beam at Atlantis. Dr. Weir attempted to negotiate with Oberoth, but he simply tried to upload a virus into the Atlantean computers.

Later, during an attempt by Sheppard's team to steal a ZPM from Asuras when Atlantis is stranded in space, Weir, infected with Asuran nanites keeping her alive, confronts Oberoth and makes physical contact with him, connecting herself to the Replicator network. She uses her access to freeze all of the Replicators and fool Oberoth into thinking he had captured the team to give them time to escape. Sheppard, not wanting to leave Weir behind, goes to search for her. However, Oberoth begins to resist Weir's control over the network and manages to physically grab her arm. Weir pleads for Sheppard to run and leave her behind. Sheppard is forced to run back to the Jumper and escape without Weir. During this exchange Oberoth is clearly impressed with Dr. Weir's tenacity, even admitting to admiring it, yet seriously underestimates her.

He is presumably destroyed in Be All My Sins Remember'd when the team destroys the Asurans with help from the Wraith and the Travelers.

Talus

Template:Stargate character Talus was an Asuran and enemy of Dr. Elizabeth Weir and her team.

Talus was in command of the attack team sent to capture Atlantis in retribution for the Ancients' betrayal millennia ago. As the handful of Ancients who had recently retaken control over their city were still under the impression that the Asurans were unable to harm their creators, due to a directive that had been deleted from their base programming some time ago, they were unprepared for the invading Asurans. After Talus and his team had taken control over the city, they killed the surviving Ancients after having probed their mind.

Although the SGC had decided to destroy Atlantis after the city had fallen to the invadors, Dr. Weir disobeyed orders and travelled back to the Pegasus Galaxy accompanied by John Sheppard and Carson Beckett in a Puddle Jumper. After having enlisted the help of Ronon Dex and Teyla Emmagan, the Jumper travelled through the Stargate to the fallen city.

Unable to raise the Iris shield, Talus was present in the Gate Room when the invading Jumper emerged. Although the ship was heavily fired upon, the Jumper escaped by breaching the Gate Room's outer wall, and dropped explosives before departing, heavily damaging the Control Tower. Talus however was able to escape before the bomb detonated.

Realizing the Jumper briefly communicated with survivors still hiding in the city, Talus sent search parties to find the ones Sheppard came to rescue. When the Jumper later reappeared, he ordered his subordinates to shoot it down, although Sheppard was able to avoid the Drone weapons fired at him. After the search parties discovered General Jack O'Neill and Richard Woolsey, the two were captured, and Talus probed O'Neill's mind for information.

As Rodney McKay had fed Woolsey misinformation in an attempt to deceive the Asurans, Talus was unaware that Sheppard's team had been able to modify the City Shield to emit a massive energy wave, similar to the wave emitted by an ARG. Talus was subsequently killed when the wave reached his position, as the kiron pathways between his individual cells were severed, disintegrating his body in the process.

Though he is presumed to be dead, its entirely possible that the subspace link among the Asurans would allow them to replicate him as Oberoth himself was replicated after his destruction around Lantea. However, he is presumably permanently destroyed in Be All My Sins Remember'd when the team destroys the Asurans with help from the Wraith and the Travelers.

• David MacInnis also played "Williams" in SG-1 episode "Ex Deus Machina".

Atlantis Expedition

In the episode "This Mortal Coil" it was revealed that some of the replicators can take form of several members of the Altantis, particularly Drs Keller and Zelenka and Major Lorne.

They were actually part of Niam's group of replicators who wanted to ascend, but when Oberoth turned most of Niam's group back into his collective, some members escaped from Asuras and onto another planet covered with a large ocean, where they created another Atlantis and took personas of Dr Keller, Dr Zelenka and Maj Lorne as the leaders of the group. They then created organic copies, using nanites, of Lt Col Sheppard, Teyla, Ronon and Drs McKay and Weir. They implanted them with memories obtained from Weir's mind probe by Oberoth. They also created them to learn about the human 'soul' so they could be able to ascend.

Unfortunately, the organic copies became aware of this, causing Repli-Keller to resort to wiping the organic copies' memories clean and starting again; by this time Oberoth had tracked them down, but they refused to come back to the collective. The replicator ships arrived at the planet and attacked 'Atlantis'. Keller released the organic copies with a device capable of tracking every Aurora class battleship in the Pegasus Galaxy. The remainders, including Keller stayed behind and were all killed when Atlantis was destroyed.

The real Atlantis expedition were contacted by their organic copies and were able to track down the number of Replicator ships in the galaxy, but they discover to their dismay that there are several dozen of them. (McKay: "Aw, crap.")

Tau'ri made Replicators

Ava Dixon

Human form Replicator created by scientist Richard Poole on Earth. She was given social programing and was able to pass well as a human and seemed to care. Due to her programing she had emotions and considered Richard like her father. When the other Replicator created by him got loose, she tracked down Colonel John Sheppard for help against Richard's wishes and helped him. Ultimately she ran when Sheppard learned that she was a Replicator after finding out that the real Ava Dixon had been dead for a year. She hid herself from the Apollo's sensors but returned to help Sheppard and Ronon kill the other Replicator. Using her enhanced abilities she fought him but was losing when Sheppard and the Apollo managed to beam him into the atmosphere destroying him. It was later decided to have her mind downloaded into a virtual world where she could live her life but not be a security threat and her body was destroyed.

Poole's Replicator

Human form Replicator created by Richard Poole. Had military programing and when Poole went to shut him down due to the IOA closing in he broke out and escaped. He was resistant to all Anti-Replicator technology but due to his being cut off from neutronium he had limited self-repair abilities and enough firepower could bring him down. He ultimately killed Poole but Sheppard and Ronon managed to damage him. After learning how he was being tracked from Poole, he managed to mask himself from the Apollo's sensors and headed for a warehouse where there was neutronium in order to repair himself. He engaged Sheppard, Ronon and Ava Dixon there and was winning until Sheppard stabbed him with a switch-blade knife equipped with a transmitter causing the Apollo to beam him into very low Earth orbit where he plunged into the atmosphere causing him to be incinerated and destroyed from the unprotected re-entry.

Fran

Template:Stargate character In the episode "Be All By Sins Remember'd", Dr. McKay used a Lantean machine, used to create the Asuran nanites, to create a human form Replicator and named her Fran (Friendly Replicator ANdroid) in order to assist with the project to turn the Asuran replicators into an enormous blob and then destroy them.

She was taken to Asuras and began the process by forcing all of the nanites to stick to herself.
