Replicator

"We have an enemy in our home galaxy that is far worse than the Goa'uld."

- Thor

Replicators are advanced robots and they can indefinitely create more robots. Unfortunately, they will use up all available resources to create more of themselves, hence the name.

Creation
The creator of the replicators was an android herself, named Reese, who made them as toys, but eventually taught them to protect themselves as well as herself. When they grew in numbers she lost the ability to control them. They destroyed her world and all the people on it, and left her intact.

The Asgard had big problems with fighting the threat that was the Replicators. Their alliance with the Tau'ri was very beneficial, as guns were able to destroy the Replicators, and Samantha Carter was able to save Othalla by having the Replicators follow the O'Neill, then rigging it to explode. But the tide soon turned against them. After their homeworld was overrun by the Replicators, they triggered a weapon that eventually froze all the Replicators in time.

After this was done, the Asgard devised a plan to destroy the Replicators, they increased the gravity on Halla's sun, collapsing it into a blackhole. Fifth was able to use the time dilation device to escape the immense gravitational pull of the black hole and escaped in a ship made out of Replicator blocks. These Replicators made their way to Orilla, where Fifth was able to make a duplicate of Samatha Carter. Jack O'Neill, under the influence of the Ancient's repository of knowledge, was able to build a Replicator disruptor, which severed the keron pathways in the blocks. The Asgard made good use of the device, eventually driving them from the Ida galaxy.

This duplicate later killed Fifth so that she could rule the Universe herself. The Replicators later left the Ida galaxy and invaded the Milky Way, completely destabalizing the Goa'uld Empire in the process. The Replicators were wiped out when the Tau'ri and Jaffa Rebellion were able to use the superweapon on Dakara to destroy them.

Replicator Blocks
Each replicator is composed of a series of Replicator blocks. Each block is many Keron pathways. It takes several blocks working together to make new blocks. Replicators are capable of forming many patterns determined by what they need to accomplish. Although Replicators usually take the form of "bugs," they can take other forms.

Behavior
Replicators seek out the most advanced technology they can find, and incorporate it into their own being. Generally, replicators will not attack unless threatened. This behavior will change, however, if there is a Human Form Replicator controlling them.
