"There's assassin probes down here!"
Anakin Skywalker — Quote-audio Listen (file info)[src]

The SD-K4 assassin droid,[4] also known as the assassin probe,[3] was a model of assassin droid manufactured by the Techno Union.[1] Used by the Confederacy of Independent Systems during the Clone Wars, it was also referred to as the Separatist assassin probe[5] and Separatist assassin droid.[1]


A fourth class droid,[2] the SD-K4 assassin droid[4] was designed to assassinate targets with high efficiency.[6] Spider-like droids programmed for quiet killing, assassin probes moved[5] quietly[6] on eight razored legs they could use to lurk silently in for the kill.[1] They were equipped with multiple[5] red[3] photoreceptors for scanning their surroundings. If cornered[5] or destroyed,[1] an SD-K4 could release dozens of smaller[5] probe killers[7] from pores on its head[5] to finish any job the assassin probe started.[6]


Manufactured by the Techno Union,[1] SD-K4 assassin droids were used by the Confederacy of Independent Systems during the Clone Wars.[3] As the Galactic Republic's highest echelons began disappearing, it suspected the use of assassin probes.[6] In the year 21 BBY,[8] Tal Merrik, senator of Kalevala and a secret Death Watch sympathizer, smuggled three SD-K4s aboard the spaceliner Coronet to assassinate Satine Kryze, duchess of Mandalore. However, the trio and their probe killers were destroyed before they could eliminate their target, though not before killing several of her clone trooper security detail.[3]

After the Clone Wars, the Techno Union was absorbed by the Galactic Empire,[9] who used their assassin probes during the Galactic Civil War. The Rebel Alliance also modified some for combat and provided them to Saponza's Gang.[4]
