After the effect of Vorash's sun going supernova caused Apophis' mothership and Cronus' Ha'tak to travel to a distant galaxy and the ship was infested by Replicators. Apophis, a brainwashed Teal'c, and several Jaffa escaped in this Tel'tak. Teal'c contacted SG-1 aboard Cronus' Ha'tak and landed in the cargo bay. Apophis and Teal'c took control of the Ha'tak and set a course for Delmak. Unfortunately, a Replicator stowed away on the Tel'tak in a crate and began to take over the Ha'tak. After the Replicators increased the speed of the Ha'tak and it arrived at Delmak, Colonel Jack O'Neill and Major Samantha Carter destroyed the sublight engines and SG-1 and Jacob Carter escaped in the Tel'tak before the Ha'tak crashed into the planet, finally killing Apophis.
