Dante

A character who only appears in the TV series. A biker gang leader who learned Nanto Seiken with Shin. His style is Nanto Hyakuzan Ken ("South Dipper Hundred Slash Fist"), which focuses on slashing techniques and the use of boomerangs. He has a tendency of kissing his victims after killing them. He blackmailed Duran (his former partner in crime) into trying to kill Kenshiro. He murders Duran for his failure but Kenshiro defeats Dante shortly after, using the Hyakuretsu Ken and striking the Gusoku (具足?) vital point to make him walk helplessly into the volcano.
