Teal'c

"Teal'c, I saw you stand up to a god. You refused to kill. I saw you make that decision... In that moment I learned everything I needed to know to trust you"

- Jack O'Neill, Leader of the Stargate Team. Teal'c of Chulak [pronounced ˈtiːəlk], also known as Teal'c, and sometimes refereed to as Shol'va by those allied with the Goa'uld, is a Jaffa from the planet Chulak who formerly served the Goa'uld and System Lord Apophis as his First Prime.

During his tenure as First Prime, Teal'c was forced to commit many atrocities in his god's name with Teal'c later beginning to suspect that Apophis was not God. In July 1997, Teal'c eventually gained the strength and courage to finally abandon his service and devotion to the Goa'uld forever which he achieved by defecting from Apophis and joining the Tau'ri, Teal'c pledging his loyalty to Stargate Command and also the cause of the Jaffa Rebellion.

After being regarded as a possible candidate, Teal'c was eventually accepted as a member of the SGC and was later assigned to the SGC's flagship team, SG-1 on a permanent basis with Teal'c's own knowledge about the Goa'uld themselves giving the SGC a huge advantage.
