Jinx

"I guess I underestimated you. You pack quite a punch! But don't let it get to your head, because I let you HAVE that round. Let's have a rematch."

- 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, with higher attack, defense, and HP stats. He also introduces Quicksilver in the second fight and Bombs Away (which has extremely high attack power) in the third 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.

The brainwashed Magikoopa of the Smithy Gang created Jinx Clones to stop Mario and his party's advance through Bowser's Keep.
