Lantash was the Tok'ra symbiote within the host body of Martouf. Although less patient with the Tauri than his host, Lantash was a friend and ally of Earth and he worked closely with the SGC as a liaison to the Tok'ra. When Martouf was programmed as a zatarc, he was shot multiple times to prevent him from carrying out an assassination. His body was kept in stasis for months, trying to find a way to repair the damage, but Lantash was too weak to heal his host, and Martouf died. Lantash remained in stasis until a new host could be found. When the Tok'ra base at Revanna came under attack, Lantash's stasis chamber was destroyed, and he entered the injured Lieutenant Elliot as a new host. However, Elliot's injuries were too severe for Lantash to heal, and neither was expected to survive. Surrounded by the advancing forces of Zipacna, Elliot/Lantash volunteered to sacrifice themselves by staying behind to release a poison that would target symbiotes, in order to destroy Zipacna and his army of Jaffa, and to allow SG-1 to escape.
