Sean Waltman 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.
Waltman has won a dozen championships between WWE, WCW, and TNA; the majority were cruiserweight and tag team titles. He is the only wrestler to have held the TNA X Division Championship, the WCW Cruiserweight Championship and the WWF Light Heavyweight Championship; he also held the WCW Cruiserweight and WWF Light Heavyweight titles simultaneously. He was also the final WWF Light Heavyweight Champion before the title was retired in favor of the Cruiserweight Championship he simultaneously held.
He was part of The Kliq, a group of wrestlers known for their influence on WWF storylines in the mid-1990s, and also reached new heights of popularity as a member of the New World Order (nWo) in WCW and then moving on to WWE and joining the stable D-Generation X during the Attitude Era.
Sean Waltman will be appearing at Niagara Falls Comic Con all three days.
