Jinx

Jinx is a sensei and operates a dojo in Monstro Town during Super Mario RPG: Legend of the Seven Stars. Although he is extremely small, he is also enormously powerful. When Mario first arrives at the dojo, he challenges Jinx's student Jagger to a fight. After beating Jagger, Mario can fight the martial arts master Jinx. Jinx will fight Mario three times, getting exponentially stronger with each fight. After Mario wins the third fight, Jinx rewards him with the Jinx Belt, the symbol of his power. Jinx also declares Mario the new sensei of the dojo. Jagger and Jinx then begin to train in Mario's style of martial arts. Their first training assignment is to Jump one thousand times.
