7. Samurai Del Sol
Samurai del Sol, also known as Kalisto, is a WWE wrestler of Mexican origin and one of the most mysterious wrestlers in history. Not only did he change his name a few times, but also his mask, yet he hasn’t ever shown his face in public, which makes wrestling fans wonder what he actually looks like. Despite his efforts to remain anonymous, one time during a fight, his opponent managed to pull his mask up by mistake, revealing his face. Can you believe this is the only available picture of his face? It is not much, but it was enough to shake fans up. After the incident, Kalisto became even more careful than he was before about showing his face.
