Sean Michael Waltman (born July 13, 1972) is an American professional wrestler. He wrestled for the World Wrestling Federation (WWF, now called WWE) under the ring names 1-2-3 Kid and X-Pac intermittently between 1993 and 2002, World Championship Wrestling (WCW) as Syxx, and Total Nonstop Action Wrestling (TNA) as Syxx-Pac and Sean Waltman. He is currently signed with WWE working in their Legends program. Waltman has won a dozen championships between WWE, WCW, and TNA; the majority were cruiserweight and tag team titles.

As The Lightning Kid, Waltman had his WWF tryout match in Phoenix, Arizona, the day after WrestleMania IX, against fellow hopeful Louie Spicolli (soon known as Rad Radford in the WWF). He reminisced that he was lucky to have an opponent with a vested interest in an impressive match, rather than (as was then typical) a disinterested WWF veteran jobber like Virgil or Jim Powers.  After earning a contract, he made his TV debut as The Kamikaze Kid on Monday Night Raw on May 3, losing to Doink the Clown. He quickly became The Cannonball Kid, then simply The Kid. He scored an upset pinfall on Razor Ramon on the May 17 episode of Monday Night Raw, thus becoming The 1-2-3 Kid. Razor challenged him to a rematch, wagering $10,000 of his own money. Kid accepted the challenge, but grabbed the money and ran from the arena during the match. Ted DiBiase, who was feuding with Razor, taunted him over losing to a nobody. This angered Kid, and led to a match in which he upset DiBiase as well. Razor turned face shortly after and took Kid under his wing. The 1-2-3 Kid made his pay-per-view debut at SummerSlam, losing to DiBiase's tag partner Irwin R. Schyster after Razor had defeated DiBiase. At Survivor Series, Kid was on Razor's team in a four-on-four elimination match. He and Marty Jannetty were the sole survivors, which led to them forming a tag team and holding the Tag Team Championship for a week in January 1994 after beating The Quebecers.  For the next two years, The 1-2-3 Kid was a natural underdog and fan favorite. He wrestled Bret Hart in an unusually long (for the time) and highly acclaimed match for the WWF World Heavyweight Championship in July 11, 1994 on Raw and had another brief (one-day) tag title reign in January 1995, with Bob Holly beating Bam Bam Bigelow and Tatanka at the 1995 Royal Rumble before losing to The Smoking Gunns on Raw.  On September 16, 1996, Waltman was shown sitting in the front row for a live episode of Nitro. Later that night, he stood and used a remote control to release New World Order (nWo) propaganda from the ceiling, revealing himself as the newest member of the recently formed faction. He was called Syxx, because he was the sixth member of the nWo, and six is the sum of numbers in "1-2-3 Kid".  In his first major angle, Syxx stole Eddie Guerrero's WCW United States Heavyweight Championship belt, leading to a ladder match for the title at Souled Out in January 1997, which Syxx lost. The next month, at SuperBrawl VII, Syxx pinned Dean Malenko for the WCW Cruiserweight Championship, after hitting him with the title belt, which he had grabbed from Guerrero at ringside. In June 1997, he lost the championship to Chris Jericho at a webcast house show in Los Angeles, California, minutes after successfully defending against Rey Mysterio, Jr.  During a feud with Ric Flair, and a loss to him at Road Wild in August, Syxx disparagingly portrayed Flair as part of an nWo segment parodying his Four Horsemen group. This segment led to a WarGames match at Fall Brawl, where Syxx, Kevin Nash, Buff Bagwell and Konnan defeated The Four Horsemen (Flair, Steve McMichael, Chris Benoit and Curt Hennig) after Hennig betrayed the Horsemen and joined the nWo. In mid-1997, the nWo invoked "Wolfpac Rules", allowing Syxx to replace the injured Kevin Nash in defending the WCW World Tag Team Championship with Scott Hall. On October 13, 1997, Hall and Syxx lost the title to The Steiner Brothers (Rick and Scott).  In October, a neck injury sidelined Waltman from wrestling, but he continued to appear on TV for several weeks after. While later recuperating at home, he was fired via Federal Express by WCW President Eric Bischoff. Waltman claims this was a power play aimed at his friends Hall and Nash, whose backstage influence was felt as a threat. Bischoff later said Waltman was a competent performer when sober, but sober periods were "few and far between", and "in many ways, Sean was lucky to even have a job".  Waltman returned to WWF TV on the March 30, 1998 episode of Monday Night Raw, the night after WrestleMania XIV and days after his firing from WCW. With Shawn Michaels beginning a four-year retirement after a WWF World Heavyweight Championship loss and back injury, Triple H was now the leader of D-Generation X (DX). He said he was forming a DX army and "when you start an army, you look to your blood... you look to your buddies... you look to your friends... you look to The Kliq." Waltman appeared on the stage, commented on Bischoff and Hogan, and said if they weren't contracted to WCW, Hall and Nash would have also returned to the WWF. Bischoff responded on Nitro the next week by telling Waltman to "bite me".  Initially called "The Kid" on the WWF website, he became known as X-Pac by the next Raw. X-Pac feuded with Jeff Jarrett, ultimately defeating him in a hair-vs-hair match at SummerSlam, then with WWF European Champion D'Lo Brown, whom he dethroned on September 21, 1998. He re-lost the title to Brown two weeks later, then won it again at Judgment Day: In Your House in October. Waltman lost the title to Shane McMahon on February 15, 1999. At WrestleMania XV, he lost a championship rematch when Triple H betrayed him, and hit him with his Pedigree finisher.  X-Pac then sided with Road Dogg against Triple H, Chyna and Billy Gunn, after the temporary demise of DX. X-Pac and Road Dogg wanted a reformed DX to be about rebellion, while the others wanted it to be about making money. X-Pac became a face and befriended Kane, a mute, angry loner whom he partially socialized and encouraged to speak, through an electrolarynx. They won the WWF Tag Team Championship twice together. After DX reunited in late 1999 as a heel group, X-Pac led Kane to believe he would be inducted into DX, but instead betrayed him and eventually stole his new girlfriend, Tori.  In 2000, X-Pac feuded with fellow DX member Road Dogg, and Chris Jericho, whose botched powerbomb sidelined Waltman for three months with another neck injury.
