Kenshiro (ケンシロウ), or just Ken as he is often called, is the central character of the Hokuto no Ken manga, anime, and other related works.
He is the 64th successor to the Hokuto Shinken art of combat, after his adopted father, Ryuken. He is considered "one of the greatest" successors in Hokuto Shinken history, due to his knowledge of certain legendary techniques like Musou Tensei. He is also known for his famous catchphrase: 「お前はもう死んでいる。」 ("Omae wa mou shindeiru." / "You are already dead.")
After the nuclear war, his fiancee Yuria was taken by Shin, who defeated Kenshiro and craving the infamous seven scars on his chest. Kenshiro along with two orphanted children who later joined his cause, Bat and Lin, started his journey to taking back his fiancee from Shin. This would leading to several chains of events involving him saving the innocents from various ruthless bandits factions for their survival, and that made Kenshiro being later called as "The Savior of century's end".
Kenshiro's trademark technique, in which Ken strikes the opponent's body with a relentless flurry of punches aimed at key pressure points, resulting in full body explosion. Usually delivered with Kenshiro's famous "ATATATATATATATATA" kiai.
