There is an unused character found in the SNES version's data named "??Mystery??". He appears to be a placeholder for a 13th wrestler who wasn't finished. His sprites are borrowed from Shawn Michaels, but the palette used gives him grey hair and boots, pale skin, and black pants; and when performing certain moves, his sprites change to Bret Hart. He also lacks a finishing move, a theme song, portraits and a biography on the wrestler selection screen, and graphics for the Titantron that appears when winning a match. The Genesis version contains a variation, but this one resembles Razor Ramon.
