Replicator Carter
Replicator Carter (more commonly referred to as RepliCarter, and rarely referred to as 'Carter2' or 'Replica Carter') is a character from the science fiction television series Stargate SG-1. She 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 in Stargate SG-1's eighth Season.
RepliCarter is extremely strong and agile, and like other human-form Replicators, she wears a grey outfit. She is rarely seen without clothes, and is usually most recognizable by the ruthless and taut expression she wears in contrast to the selfless appearance of Samantha Carter. Both characters are played by the same actress, Amanda Tapping.
RepliCarter, like other human-form Replicators, is also invulnerable to both projectile and energy weaponry. She possesses the abilty to reform herself at any time, not only to heal but also to shape her arm into a weapon like a long sword, with which to suddenly kill enemies. This highly resembles the method of murder used by the antagonistic Terminator in the film Terminator 2: Judgment Day, and may be an intentional joke. She also possesses the ability to deactivate portions of herself.
Notably, the only time that Replicator Carter is named on the show is when Daniel Jackson calls her by that name in an almost descriptive fashion. Her actual name might be 'Eighth', or she may have had no name at all.
Origin
Replicators are generally an insentient race of machines. Every Replicator is constructed from the conjoinment of maybe a hundred, or up to millions, of individual Replicator cells. These cells are all identical and are reproduced (hence 'Replicator') from any strong metal.
Human-form-Replicators, as their name suggests, take perfect human form. Although they are made out of the same metallic cells as other Replicators, these are somehow masked so that the being appears to have normal human skin. Five of these were made as leaders, and the fifth, named 'Fifth', was the first to be engineered with emotional capacity. This led to him falling in love with Samantha Carter (more of an infatuation), and when he realised he couldn't have her, he created a perfect replica of her.
Plot
Rise
Fifth intended for RepliCarter to govern the Replicator race with him, and be his consort (of sorts; even human-form-Replicators do not copulate). Due to his infatuation with Samantha, he made her exactly in her image, down to the very last memory and character-facet. This in part led to her despising what he was trying to do as much as the original Samantha Carter would have.
The differences between Samantha Carter and RepliCarter are quite pronounced. Namely that RepliCarter is a megalomanic, ruthless, dominating conquerer. She wishes to control the entire galaxy, and claims that this desire is also within the original Samantha Carter, just that she never had the bravery, or means, to act upon it. When Samantha denies this, RepliCarter replies that "all humans desire power." Replicarter also is connected to the Replicator datastream.
At the beginning of Season 8 (the episode "New Order (Part 1)"), Jack O'Neill engineered a weapon that is able to disintegrate any Replicator in its blast-radius (the 'Replicator Disruptor'). This weapon would become the defining piece of technology in the fight of the SGC against the Replicators.
RepliCarter fools Fifth into believing that she is loyal to him, and maybe even likes him. In the episode "Gemini" they execute a plan to discover how to immunise their race from the Replicator Disruptor. This involves sending RepliCarter to the SGC with a false story that will make the humans help her. She says that Fifth has cast her out in spite, and that she wants to be destroyed by their Disruptor as she hates her existence. SG-1 take her to the Alpha Site to question her. She informs them (untruthfully) that Fifth has immunised every single Replicator to the Disruptor, all except her in spite. However, she tells them she will help them realign the Disruptor to work around Fifth's immunisation.
They begin work on the Disruptor, but what RepliCarter is actually doing is studying the Disruptor so she can find out how to immunise her race from it. She relays this information back to Fifth, and keeps in communication with him, via an undetectable datastream that exists between all Replicators called The Link. Unbeknown to the SGC and SG-1, Fifth is tracking her position and is bringing a powerful Replicator ship in attack towards them.
RepliCarter betrays Fifth by firing the Disruptor at his ship before she uploads the cipher that will immunise it. Both he and his ship are destroyed. RepliCarter then immunises herself and her race, and leaves the Alpha Site via its Stargate. Teal'c tries to stop her and forces her to leave her arm behind. This decomposes into its deactivated cells, which Samantha Carter begins studying, feeling responsible for the victory of RepliCarter due to trusting her in the first place.
RepliCarter subsumes Fifth's position and becomes the leader of the entire Replicator race, and begins on an aggressive attack against the major ruling power in the galaxy, the Goa'uld System Lords. This continues in the background throughout the Season.
Fall
In the episodes "Reckoning (Parts 1 & 2)", SG-1 and the Tok'ra begin to seriously consider the threat that RepliCarter poses to the galaxy. In the meantime, the Jaffa Rebellion gets underway, and Teal'c and Bra'tac, along with many Free Jaffa, take over the Temple at Dakara, an act that they believe will make all Jaffa come to their cause.
They discover that the Temple at Dakara was not of Goa'uld origin, but of Ancient origin, and is in fact the home of the Dakara Superweapon. This weapon has the ability to decompose all matter in its blast radius into its separate atoms, i.e. it can destroy all galactic life. It is believed that this weapon's power was actually once used to create life in the Milky Way.
Samantha Carter goes to study the weapon, hoping to be able to realign it to make it destroy only Replicators. She realises that the Replicators can immunise themselves to the Disruptor only after they have seen it in action, and so a single blast that destroys every Replicator at once will be the only way to eliminate the threat. She can do this only if the blast-radius of the Weapon is extended by using the Dakara Stargate to create an outgoing wormhole to every other galactic Gate, but she will need outside help for this. Jack O'Neill stays at the SGC, Teal'c guards the Temple with the Free Jaffa, and Daniel Jackson is captured by RepliCarter.
On-board RepliCarter's ship, Daniel's mind is probed by RepliCarter for the Ancient knowledge it contains, subconsciously left over after his de-Ascension. This knowledge is the only threat to RepliCarter's rule. She discovers the location of the Dakara Superweapon, and heads there immediately, whilst continuing to absorb Daniel's vast knowledge.
The System Lord Baal, the dominant ruler of the Goa'uld, under Anubis then turned his fleet on Dakara, to drive out the Rebel Jaffa. However, Teal'c speaks to him and they negotiate that he will allow Samantha Carter time to study the Superweapon, as the Replicators are a common threat and the alternative is that Anubis will use the Superweapon to wipe out all life in the galaxy bar his own.
The Replicators arrive at Dakara and begin to attack. In the meantime, Daniel, whilst allowing RepliCarter to enter his mind, has fooled her and been working his way into her mind. He is now able to see that RepliCarter, against her own word, has attacked the SGC. Time is running out for Sam, and for one moment Daniel is able to freeze every single Replicator in the galaxy. This gives Jack enough time to survive, and Sam enough time to finish her realignment of the weapon. Baal helps Sam to reprogram the Dakara Stargate to dial every single Gate in the galaxy simultaneously, and the Superweapon is fired, but not before RepliCarter kills Daniel. After that, she is destroyed along with all of her race. Template:Recurring characters on Stargate SG-1
