The Cheetah Kid
WWF Monday Night Raw - January 11, 1993
One of the dark matches on the first ever episode of Monday Night Raw was The Cheetah Kid vs. Johnny Rotten. At the time, they were independent wrestlers who were largely unknown. Later that year, these opponents made their debut as a tag team at ECW Ultraclash in Philadelphia using the personas that they would use for the rest of their pro wrestling career. The Cheetah Kid became "Flyboy" Rocco Rock and Johnny Rotten became Johnny Grunge. Together as The Public Enemy, they were four time ECW Tag Team Champions. They also won the WCW and NWA tag team championships
I don't know if video footage exists of this dark mach from the first Monday Night Raw, but at least one photo of Rocco Rock as The Cheetah Kid is out there. It was shared last October by Richard Land (@maskedwrestlers on Twitter and editor of The History Of WWE).
