X-Pac -- (born July 13, 1972, as Sean Waltman, in Minneapolis, MN) is a professional wrestler who worked for the World Wrestling Federation as the 1-2-3 Kid and later X-Pac, World Championship Wrestling as Syxx, Total Nonstop Action as Syxx-pac (and his birth name), and Wrestling Society X. Additionally, he is known as Chyna's ex-boyfriend in some circles, and the two made a sex tape in 2004 called "One Night in China" (a spoof title from "One Night in Paris"). X-Pac is considered as one of the pioneers of high-action wrestling in the United States.
He first received attention in the wrestling world for his brief time in the Global Wrestling Federation from Houston, TX, where he wrestled as the Lightning Kid. When the WWF hired him, they introduced him as an enhancement talent for several weeks before giving him an upset victory over Razor Ramon, leading to his first ring name of the 1-2-3 Kid. Although the Kid never headlined for the WWF, he received a solid reputation as a great worker. He also joined the Kliq, so when Razor and Diesel moved to WCW, he was released from his contract and permitted to join them.
While in WCW, Syxx was given suitable TV time with the New World Order, but most experts saw him as nothing more than a pawn in a power struggle between the Outsiders and Eric Bischoff. Supporting this evidence was his foolhardy 1998 release, which enabled him to join The DX Army right when he was most needed. Through DX, X-Pac logged his most consistent performances from 1998 through 2000. He led a faction called The X-Factor in 2001, but he quietly left the WWF sometime amidst the WCW Invasion. He returned to rejoin the nWo, but he quietly left the WWF after the angle was unceremoniously dropped in June 2002.
As Syxx-Pac, he worked several events for TNA in 2002 and 2004, but nowadays, he gets his most work through AAA and independent promotions.
