The Satan Castle is a fighting dojo on Earth. It is where Mr. Satan trained to become stronger.


Through a combination of considerable power and good luck (his rival fighting opponent would get food poisoning, for instance), the young Mark quickly became world champion and then was called "Mr. Satan" after the name of the dojo. One day when they were on tour, at a bar in South City, the martial arts master of the dojo and Mr. Satan made the mistake of making fun of Mercenary Tao's hairstyle, so Tao killed the master and heavily injured Mr. Satan. From then on, Mr. Satan solemnly swore never to fight anyone whose true identity he did not know, or anyone who seemed crazy strong.[1]
