Qetesh

Qetesh was a minor female Surai Underlord who once used Vala Mal Doran as a host.

Biogrpahy
An Underlord of the Surai Empire, Qetesh ruled over at least one world, P8X-412, where she forced the inhabitants to mine the planet's sparse Naquadah deposits. When quotas were not met she instituted both mass executions and mass torture. In 2361, a Tok'ra operative incited a rebellion on Qetesh's planet. The people rose up and overpowered the Surai guards, Qetesh was captured alive, tortured and beaten for days. Eventually, Vala was freed when SG-1 removed Qetesh from Vala. However, the people who had been enslaved by Qetesh didn't understand that she was only Qetesh's host and tortured her, until she was eventually freed once again by SG-1. In 2378 the Surai cloned Vala Mal Doran and Qetesh once again used Vala as her host. During this time, Qetesh was allied with an evil version of Samantha Carter.

Alternate reality
''In an alternate reality Qetesh was never removed from Vala Mal Doran in 2361. In this reality SG-1 tried to remove Qetesh from Vala but they failed. Qetesh was able to seduce Lieutenant Typhuss James Halliwell, because he was the former lover of Vala and later Qetesh and Typhuss became lovers.''
