Fist Fight Djinn (拳闘魔人, Kentō Majin; Viz: Demonic Pugilist) was a Mysterious Being who attacked Smile Man out of the blue. He was killed by Silver Fang.[1]


Fist Fight Djinn was a very muscular, four-armed humanoid boxer with spiky hair. He wore a gray tanktop and white shorts with a thick belt. He also wore headgear with a ripple pattern eye on the center of his forehead.


Fist Fight Djinn was very prideful in his abilities and eager to put his strength to the test. He seemed to be a bit violent even when he was as a human, as stated by him how he wanted to get stronger because of his "unsatisfied thirst for battle and violence."


Fist Fight Djiinn was once a boxer who used to love fighting. However, tournaments never seemed to quench his thirst for battle and violence, so his urge for power has turned him into a mysterious being.[2]
