why does rey mysterio wear a mask?

It's a tribute to his Mexiacan heritage. Down there, most wrestlers do wear masks, and since his heroes & some of his family members wrestled with the masks, so does he. However, in WCW he didn't always use it. He lost a match where the stipualtion was that if he lost, he'd have to take of the mask. If you want a picture:

Rey is indulging in the Mexican tradition of wearing a Luchadore mask. His father and Eddie Guerro did as well, back in the day. He wanted to bring his culture into a market that hadn't really experienced that much: the WWE. But if you see him with his mask off, he still looks fly.

cause hes from mexico in mexican wrestling all the wrestlers wear masks and the match is to try to remove ur opponets mask whoever gets there masck removed is shamed so he wears it to honor his tradiotn so did eddie and chavo back then and rey without his mask is cute

Its a tradition for Mexican wrestlers to wear a mask
