#4 Ken Shamrock vs Scott Hall
Ken Shamrock brought legitimacy to the WWE when he signed for the promotion in 1997. The MMA legend wrestled for two years in the company, before leaving in 1999 to return to MMA.
Meanwhile, Scott Hall had wrestled with great acclaim for both WWE and WCW but found himself without a job after getting fired from WWE in 2002. Hall soon jumped to the newly formed NWA: TNA and was part of the company's first weekly PPV and competed in a battle royal to crown the first NWA World Champion in TNA.
And who captured the gold ?? It was Shamrock, returning to professional wrestling after a gap of three years. Despite being two of the most famous members of the TNA roster, Hall and Shamrock's paths never crossed after the battle royal.
Both were gone from the company almost immediately with Shamrock's title defences coming against the likes of Malice and R-Truth.
Hall had several forgettable runs with the company but never recaptured his WCW prestige.
