#1 Kevin Nash (1999)
It was 1999 and Mysterio was teaming with Konan to face Kevin Nash and Scott Hall in a mask vs hair match at WCW Superbrawl IX. Konnan and Mysterio came within moments of winning on a couple of occasions but it wasn't to be.
After their loss, Mysterio was forced to unmask in what was probably his most famous unmasking on American television.
Mysterio later spoke about not being a fan of this unmasking saying:
“I don’t think WCW understood what the mask meant to me, to my fans and to my family. It was a very bad move on their behalf. The fans wanted Rey Mysterio with the mask and losing it hurt me a lot. It was also frustrating that it didn’t come as the climax to a feud with another masked wrestler but in a throwaway match.”
Mysterio returned to the mask as soon as he signed for WWE.
