Qetesh (Continuum reality)

Qetesh was Ba'al's Goa'uld queen in an alternate reality where she wasn't removed from Vala Mal Doran by the Tok'ra. After she killed Ba'al, she has been killed by an alternate Teal'c while she tried to control the Praxyon time machine.

Biography
Unlike the main timeline Qetesh who has been removed from Vala Mal Doran by the Tok'ra in 2001, Ba'al prevented this to happen by keeping Qetesh at his side for 50 years.
