北斗神拳
is the third of the four Hokuto brothers. Deceptive and evil, Jagi stops at nothing to win and frequently cheats during battle. He never really mastered Hokuto Shinken, relying on his sawed-off shotgun to finish off most of his opponents. After a botched attempt at killing Kenshiro, he is left with a hideously disfigured head as a reminder of his failure. Consequently, he hides his head by wearing an iron helmet and a section of plating over the disfigured portion of his face to control the constant pain it produces. Harboring a severe hatred for Kenshiro, Jagi was the one who manipulated Shin into betraying Kenshiro. Afterwards, he engraves seven scars on his chest in the same Big Dipper-like pattern as the ones on Ken's chest and began terrorizing numerous villagers with his gang, while claiming to be the true Kenshiro himself. Kenshiro tracks him down and easily defeats him, despite Jagi having somehow learned basic Nanto Seiken as well as Hokuto Shinken. His face finally starts exploding but as he dies he reveals that Toki and Raoh are still alive and gleefully declares his hopes that Kenshiro would be destroyed in the battles to come.
