Unknown

From Smackdown! - Wiki on Neoseeker

'Unknown' is a collective term for a variety of wrestlers used in WWF SmackDown! 2: Know Your Role. The idea was that in season mode, you would meet Unknown backstage and winning the match against him would unlock his clothing and moveset. The characters would also have a letter associated with it, to help identify the moveset - as movesets were based on pre-existing wrestlers as follows:

Unknown A: Ric Flair (Figure of Four, and The Strut)
Unknown B: Kevin Nash (Jacknife 2 and his signature elbow in the corner)
