ASN-121/Legends

ASN-121 was a hovering ASN courier droid (read: assassin droid) similar in appearance to a remote. It could wield a number of weapons, including a flamethrower, harpoon, sniper blaster, gas dispenser, and various drills and cutters. The droid was capable of emitting disruptive energy beams, which allowed it to bypass security screens. Other implements, like spy sensors, could also be attached to the droid's modular frontal tool chuck. Powering the droid was a fusion reactor, which required a power converter array to mediate the energy flux. This converter array could also double as a self-defensive electroshock device.

In 22 BBY, bounty hunter Zam Wesell used the droid in an attempt to assassinate Senator Amidala, who was residing in a senatorial apartment in a Coruscant skyscraper. The droid cut a hole in the window of Amidala's chamber, and through this hole inserted a canister containing two kouhun worms.

When Anakin Skywalker and Obi-Wan Kenobi sensed a disturbance in the room, they saved Padmé by slashing through the worms using their lightsabers. In order to find out who sent ASN-121, Obi-Wan jumped through the window and grabbed the droid. It attempted to shake Kenobi off, but Wesell fired a sniper rifle and destroyed it, leaving Kenobi free-falling until he was saved by Anakin's stolen airspeeder.
