Asexual, female personality
|Out of universe information|
Isis was a key character in that the discovery of the Egyptian treasures from the ill-fated Stewart expedition included a canopic jar that held the remains of a symbiote presumed to be that of the Goa'uld Isis. The seal on the canopic jar had been broken during transit, rendering the creature inside it dead.
An autopsy was performed on the symbiote at the SGC, and further examination of the canopic jar revealed that it was designed to function as a stasis chamber, imprisoning the symbiote presumably by Seth, according the Egyptian legend. Having found Isis in the Isis jar, it was presumed her companion, Osiris, was imprisoned similarly; however, the Osiris jar listed among the artifacts was missing.
