Star Wars Rebels Season 3 Episode 13 - Warhead Episode Title:Warhead.Episode Description:While the rest of the Ghost's crew and Phoenix Squadron are away on an exercise mission, Zeb is left in charge of security at Chopper Base. At the same time, the Empire launches a large number of disguised infiltrator droids throughout the galaxy, and one of these units lands near Chopper Base. Damaged by the Krykna spiders and losing its memory, it is taken in by Zeb, Chopper and AP-5; but after a warning from Agent Kallus about the nature of their foundling, Zeb tries to apprehend it. Once it realizes that it is inside a rebel base, the droid's original programming kicks back in and it adopts combat mode, and cannibalizing the base's droids to repair itself, the infiltrator proves a tough nut to crack, especially since this battle is confined to a storage area filled with explosive ordnance. After a hard struggle, Zeb and the droids manage to take it down before it can transmit its position to the Empire, but the infiltrator activates a self-destruct device inside its chassis. Faced with the prospect of the droid either blowing up the base or the Empire coming to look for it when it fails to report, Zeb instructs AP-5 to set the detonator to stall its countdown until the infiltrator transmits its collected information to the Empire. After reactivation, the droid travels back to its base ship and blasts it apart when it self-destructs; but this event nevertheless gives Grand Admiral Thrawn enough information to narrow down his search for the rebel base.
