Jaffa Main article: Jaffa The Jaffa are not strictly a separate species. They are descendants of humans who were enslaved by the Goa’uld thousands of years ago. But they have been genetically modified to make them stronger and to mutate its immune system, and reached a certain age can only survive with the help of a Goa’uld symbiote, until it matures and takes a host to control it, Jaffa can live. Without a symbiote dies. (When they reach the age at which he is called the symbiont implanted Prim’tah). The SG-1 finds a drug called Tretonina with which avoid dependence on the symbiont of Jaffa, but they create a dependency on drugs. All adults prior to the use of Tretonina had a bag in their stomachs which were used to incubate the Goa’uld larva of approximately 100 Earth years. These bags can be created on a human by a Goa’uld device (seen in “Hathor”).Through the Jaffa symbiont gain great healing abilities and great strength. But they are dependent on the symbiont for survival or Tretonina. The Jaffa are the majority of the military force of the Goa’uld. However, due to the Jaffa Rebellion, some Goa’uld, Anubis most notably, he began using other forces, like the Kull warriors as their main troops. The Goa’uld use a word: “Sholva or Shol’va” which describes a Jaffa traitor within the belief and fighting against the false gods. The most famous of them is the other member of SG-1 Teal’c. Others, like Bra’tac, follow this first “traitor”.
