E-XD infiltrator droid

The E-XD infiltrator droid was a model of recon droid used by the Galactic Empire. EXD-9 was an Imperial infiltrator droid who infiltrated the Phoenix rebel cell's Chopper Base on Atollon.

Description
E-XD infiltrator droids resembled protocol droids but were actually recon droids that were fitted with various weapons including built-in blasters. When in protocol mode, their sensors were white. In attack mode, their sensors turned red and the droids were also capable of elevating their height. Infiltrator Droids were capable of taking considerable damage in combat and could leap to great heights. They were also capable of scanning various objects and lifeforms. Infiltrator droids could also cannibalize other droids and drain their power. These droids were also programmed to pilot pods and to operate transmitters. Against Imperial protocol, the droids were fitted with a proton torpedo warhead that would self-destruct if the unit was compromised.

History
During the Age of the Empire, Grand Admiral Thrawn commissioned the creation of E-XD infiltrator droids to scour the Outer Rim Territories for rebel bases. In 2 BBY, the Empire dispatched many Infiltrator Droids to hunt for the Phoenix rebel cell's base. One of these units, EXD-9, discovered Chopper Base on the planet Atollon. After being attacked by krykna spiders, he was adopted by Garazeb Orrelios and AP-5, who believed that he would make a good inventory droid. However, Agent Kallus, who was a rebel operative called Fulcrum, alerted Zeb to the presence of the Imperial Infiltrator Droids. Following a struggle, Zeb, AP-5 and the astromech droid Chopper overpowered EXD-9 and reprogrammed him into a improvised bomb which destroyed an Imperial Star Destroyer.

Behind the scenes
