Shak'l was a First Prime Jaffa warrior in the service of Apophis and was introduced in the episode, 1.08 "The Nox". He was killed by Teal'c in the episode, 1.16 "Cor-ai".
Teal'c trained Shak'l while both served the Goa'uld System Lord Apophis. SG-1 met up with him on the planet of The Nox (P3X-774). As much as Teal'c tried to pursuade him, Shak'l did not want to turn against Apophis. The Nox sent him away through the stargate. (1.08 "The Nox")
Teal'c met up with Shak'l again on the planet Cartago (P3X-1279). Shak'l believed himself at an advantage in killing Teal'c as he was bound, but Teal'c was freed by a boy and killed Shak'l with his own weapon. (1.16 "Cor-ai")
