6 current WWE Superstars you forgot were in WCW

#4 Kane

Bruiser Mastino in WCW; he would later go by the name Kane in WWE

Kane, along with The Undertaker, is one of the longest-serving current Superstars in WWE. Although he may wrestle just a few matches each year, The Big Red Machine still appears from time to time on WWE TV, especially for the Saudi Arabian PPVs.

Not many fans would know that before debuting in WWE, Kane had one solitary match in WCW. This match came back in 1993, when he was still a young wrestler, and wrestled future WWE Hall of Famer, Sting. Kane debuted on WCW with under the ring name Bruiser Mastino and lost that match against the WCW icon.

Two years later, he signed with WWE, debuting as Unabomb, then adopting the Isaac Yankem gimmick, and later as fake Diesel. The Kane gimmick was debuted later in 1997, and he was involved in several fascinating feuds over the next two decades.

Kane has gone on to win numerous titles in WWE and is a Triple Crown and Grand Slam champion in the promotion.
