Aschen
Seemingly benevolent species that, by the Earth year 2010, helped humanity create a Golden Age through advanced technology.

Jaffa
The Jaffa race has a symbiotic relationship with the Goa'uld in that they carry infant Goa'uld symbiotes in pouches in their bellies. This larval symbiote guarantees its host immunity to diseases.
