In "Mass Effect 3" he was among the forces deployed during Udina's coup on the Citadel Council, and will succeed in assassinating the salarian councilor unless Thane Krios or Kirrahe are available in "Mass Effect 3" to intervene. Kai Leng is next encountered on the asari homeworld Thessia, where he successfully claims an ancient Prothean-made VI from the asari on the Illusive Man's orders. Shepard's final encounter with Kai Leng is in the Illusive Man's observation deck on Cronos Station, the Cerberus headquarters. Despite his lethal skills, he is unable to overwhelm Shepard, and is wounded. He later retrieves his blade and makes a final attempt to kill the Commander from behind. At that moment, Shepard detects him and counters his attack, finishing him off with an omni-blade.
