In WWF Smackdown 2, every three months in Season Mode, the first Raw has a scheduled wrestler ambushed backstage. It follows up with your wrestler walking past a mysterious wrestler. The ambushed wrestler is found injured, and afterwards unable to participate in his/her match. This match gets replaced with you taking on the mysterious wrestler you saw backstage. Win this match, and you unlock new CAW parts and the corresponding moveset, including new moves.

These are those mysterious wrestlers, and go by "Unknown [insert corresponding letter here]."

Also, their movesets here are based on their Smackdown 2 movesets, so they may be loosely based on their real life counterparts. Though I did add a few touches with each moveset to reflect the wrestler they're portraying further, mostly because those moves weren't in the game.

Their music files are "Unknown [corresponding letter].mp3," and all of them except for Unknown F come out to the original Smackdown theme. Unknown F, for whatever reason, comes out to "No Chance in Hell."
