#2 Former WWE star Thurman 'Sparky' Plugg
Hardcore Holly achieved moderate success in WWE, winning the tag team and Hardcore title multiple times in his 16-year-long career. However, he started his career under a different ring name.
Thurman 'Sparky' Plugg is, in no way, an exciting name suited for a professional wrestler. His gimmick was that of a racecar driver. Fortunately, the name was soon changed to Bob "Spark Plug" Holly, and Vince McMahon gifted his own race car to be used in the gimmick for free.
#1 Former WWE Superstar The Red Rooster
The Red Rooster gimmick saw the performer wear red attire, style his hair like a rooster, and even walk like the said animal. He was a client of Bobby 'The Brain' Heenan and either aligned or feuded with him throughout his run.
The man behind the gimmick is Terry Taylor, a talented performer and trainer who rapidly switched allegiances between WWE and WCW. He never fully recovered from the credibility lost due to the bizarre gimmick and retired in 2006.
