Zam Wessell (portrayed by Leeanna Walsman) is a minor antagonist who appears in Star Wars Episode II: Attack Of The Clones. Although she usually takes on a human appearance, she is actually a shape-shifting Clawdite. Early in the film, she is hired by the bounty hunter Jango Fett to assassinate Senator Amidala. For her first attempt, she plants a bomb on a landing platform when the Senator's ship first arrives on Coruscant. The Senator is not aboard the starliner, however, and instead her bodyguard and decoy Corde is killed (Padme herself was disguised as a pilot and was aboard one of the escort fighters).
When Zam tries again, she uses a pair of highly poisonous Kouhun arthropods and secretly releases them into the Senator's apartment. However, the creatures are detected by Padme's two Jedi guardians Obi-Wan Kenobi and Anakin Skywalker. Anakin kills the Kouhuns with his lightsaber before they can kill the sleeping Senator and the two Jedi notice a fleeing droid responsible for releasing the arthropods into the room. Anakin and Obi-Wan follow the droid back to Zam who flees aboard a speeder, and the two Jedi chase her through the Coruscant skylanes aboard a speeder taxi.
After a lengthy chase, Anakin and Obi-Wan find Zam in a seedy Coruscant bar. The Clawdite assassin tries to attack from behind using the crowd for cover, but Anakin is ready for her and Zam ends up being dragged outside the bar and interrogated. She is about to drop her client's name, but her client is watching from afar and silences her by sniping her with a toxic dart. As Zam dies, she reverts back to her Clawdite form.
