World Championship Wrestling and New Japan Pro-Wrestling (1996–2000) Knapik attended a wrestling show in
Florida in 1995 at the suggestion of a friend, and after calling various
promoters and
wrestling promotions, he was signed to a contract with
World Championship Wrestling later on in the year. Along with
Kenny Stasiowski, Knapik began training in WCW's
Power Plant wrestling school. Upon completion of their training, Knapik and Stasiowski debuted on WCW television under the ring names Ruckus and Kaos, respectively, and they formed the tag team
High Voltage. Shortly after debuting, Ruckus was changed to Rage. High Voltage regularly appeared against
mid-card opponents on the WCW television shows
Saturday Night and
WorldWide during the late 1990s, while also appearing as
jobbers on
Nitro. In 1997, Rage and Kaos travelled to Japan to perform for
New Japan Pro-Wrestling. Upon arriving, they began feuding with nWo Japan, the Japanese version of the
New World Order (nWo) before representing WCW in the
Super Grade Tag League. Upon their return to the United States, Knapik joined Tim Catalfo's Obake Gym and befriended
Yuji Nagata, who was also wrestling in WCW. After suffering a
rotator cuff tear, Knapik was sidelined from wrestling for seven months. On the December 21 episode of
Nitro, Rage distracted Kaos in order to allow
Lex Luger to defeat him via submission before once again confronting Kaos over High Voltage's split. However, before the
angle could develop any further, Knapik was released from his contract during his recovery.
Return to NJPW and retirement (2000–2002, 2005–2007) After leaving WCW, Knapik, under the ring name Rob Rage, returned to NJPW in 2000 and found success in the
mid-card as a singles wrestler until leaving the promotion on July 20, 2002. Knapnik went on a hiatus soon afterwards before returning to wrestling by joining the
World Wrestling Council on August 28, 2005. He remained with the WWC until September 14, 2007, when he wrestled his final match during the promotion's Septiembre Negro Tour. After retiring from wrestling, Knapik began working as a
personal trainer. ==Personal life==
