Bobby "The Brain" Heenan "unveiled" him with the persona of "Narcissus" at Royal Rumble 1993. Shortly thereafter, his name was altered slightly to "The Narcissist". Luger posed before full-length mirrors before every match. The WWF said that he had a "metal plate" inserted into his forearm which was said to cause more damage when it struck an opponent. This caused a number of his opponents to demand that he wear a cover over it during matches when he had a streak of knocking people out. This eventually led to WWF officials demanding that Luger wear an elbow pad, though he would often remove it. The Narcissist's one major feud was with Mr. Perfect. The feud was based on Heenan, his advisor, referring to him as being "Beyond Perfection," in a slight at Mr. Perfect, his former managerial client. The rivalry ended at WrestleMania IX when Luger defeated Perfect. During a WrestleMania IX press conference, Luger knocked out Bret Hart, leading to a house show feud between the two, mostly concentrated in Canada, with few (if any) of these matches being televised. At King of the Ring, Luger participated in the first-ever King of the Ring tournament on pay-per-view, but was eliminated in the quarterfinals after a time limit draw with Tatanka.
In mid-1993, after Hulk Hogan's departure from the company, Luger was transformed from a heel to a "mega-face" with the nicknames "Made in the USA" and "The All-American". On July 4, he took part in a memorable event where he arrived (by a red helicopter) on the deck of the USS Intrepid and body slammed the near 600 pound WWF Champion Yokozuna after a number of other athletes, both inside the WWF and out, attempted and failed. Following this he began the "Lex Express" tour, traveling the country in a Red, White, and Blue painted bus to greet fans and to "campaign" for a shot at the WWF Title, thus beginning a feud with the champion Yokozuna. Luger got his shot at SummerSlam 1993, with the stipulation that this would be Luger's only shot at the title. Luger, with the use of the metal plate in his forearm, eventually won the match, but the count-out victory meant that Yokozuna retained the title.
In late 1993, Luger began a feud with Ludvig Borga, another anti-American foreigner. At Survivor Series 1993, Luger captained a team dubbed "All-Americans" (Lex Luger, The Undertaker, and The Steiner Brothers) against Yokozuna's team "Foreign Fanatics" (Crush, Yokozuna, Ludvig Borga, and Quebecer Jacques) in a 4-on-4 Survivor Series match. Luger's team won the match after he pinned Borga. At Royal Rumble, Luger participated in the Royal Rumble match where he and Bret Hart were declared "co-winners" of the Royal Rumble match after both men went over the top rope and had their feet hit the ground simultaneously. As such, both received shots at the WWF Championship at WrestleMania X. Luger was disqualified in his title match against Yokozuna, and later that night Hart went on to win the title from Yokozuna.
Ever since he became a babyface in the summer of 1993, Luger aligned himself with Tatanka until rumors began to swirl that Luger was planning to join Ted DiBiase's Million Dollar Corporation in the summer of 1994. Tatanka and Luger's friendship was strained by the lack of trust between them, and a match between the two took place at SummerSlam. At the event, Tatanka defeated Luger and joined the Million Dollar Corporation. Luger continued to feud with The Million Dollar Corporation, leading a Survivor Series team consisting of himself, Mabel, Adam Bomb, and The Smoking Gunns, dubbed "Guts & Glory", to a loss against the Corporate team of Tatanka, King Kong Bundy, Bam Bam Bigelow, and The Heavenly Bodies at Survivor Series – with only King Kong Bundy and Bam Bam Bigelow surviving.
In the beginning of 1995, Luger formed a team with Davey Boy Smith, dubbed The Allied Powers and they continued to feud with the Million Dollar Corporation. They made a good impact on the tag team division and made their pay-per-view debut as a tag team at WrestleMania XI, defeating the Blu Brothers. They wrestled and defeated jobbers on Raw and, after a victory over the newly-turned heel team Men on a Mission in June 1995, earned a shot at the WWF Tag Team Championship against Owen Hart and Yokozuna at In Your House 2: The Lumberjacks but failed to win the titles. Bulldog turned against partner Diesel in a match against Men on a Mission which Luger, who was scheduled to team with Smith, was unable to participate in. While Diesel fought King Mabel at Summerslam, Sir Mo tried to interfere but was attacked by Luger, who chased him to the back. Shortly after Summerslam, Luger, whose contract had expired, left the WWF.
In 2011, Luger began working again with WWE on their Wellness Policy.
