4. Sting vs. Sting
While Sting didn’t actually wrestle his first imposter, the infamous nWo Sting (or bogus Sting) in 1996 & 1997, he did so with Jeff Jarrett dressed as Sting during an episode of WCW Monday Nitro in 2000.
It wasn’t much of an official match with an official result tho, but more of an unsanctioned tables match with the real Sting Steve Borden destroying Jeff Jarrett’s version of Fake Sting.
