The Final Battle - S2.E25

As the Argo launches torpedoes against the Comet Empire, Zordar orders the Empire to be launched. The Argo pursues the Empire, positioning itself out of range of its guns, and maneuvers itself below the Empire. Sandor discovers the Empire's weak spot: an opening in the base from where the Empire's planes are being launched.

Wildstar leads an attack team through the opening, but Sandor is hit and unable to walk. Knox, the leader of the Space Marines, says he'll finish the mission himself as a way of thanking the Star Force for rescuing them. He attaches bombs to the Empire's energy source, then detonates them, rendering the Empire unable to move. Meanwhile, Zordar escapes with Invidia, Dire and Gorse in a new space fortress.
