I know Crimson Ninja, Yellow Kitty, and Sophie were masked. Ninja went with a "Lone Ranger" style mask her last few matches. Yellow Kitty got her ass kicked and then unmasked after a match and left US. Sophia, who also couldn't wrestle for shit and always lost, left US and turned up at another Kink site without the mask and under her real name. There was another girl who wrestled in an exhibition as the Masked Avenger. It that all the hooded wrestlers there have been on the US mat?
