Not to mention secret service agent Frank Horrigan from In The Line Of Fire. And in reference to Vader, there's a Star Wars quote about Vader used about Horrigan. "He's more man than machine now." At least twice, once as a random encounter, in which he kills two people who are illicited to have worked for the Enclave. V13, you see him kill the leader of the Deathclaws. (Gruthar?) Apparently, there's a way of playing it that results in you seeing him wipe the Brootherhood out.
