Why are Black Belt and Last Battle Hokuto no Ken games?
Sega made the first console Hokuto game: Hokuto no Ken for the Mark III, released July 20, 1986, a side-scrolling beat ’em up in the mold of Kung Fu Master, in which Kenshiro’s pressure-point kills send enemies bursting apart. For the overseas Master System, Sega chose not to carry the license, and the game was rebuilt as Black Belt: Kenshiro became a generic karate hero named Riki, the manga’s cast and names were replaced, and the wasteland became a contemporary martial arts tournament story. The levels, the bosses and the exploding fists underneath remained recognizably the same game.
The sequel completed the pattern. Hokuto no Ken: Shin Seikimatsu Kyūseishu Densetsu for the Mega Drive (July 1989), covering the second era of the manga, reached the Genesis as Last Battle, a launch-era title in the West, with Kenshiro renamed Aarzak and the story rewritten around him. Generations of Western players finished both games without ever hearing the words Hokuto no Ken.
The disguise was finally retired in Japan: in 2004, the Mark III game was remade for PlayStation 2 as Sega Ages 2500 Vol. 11: Hokuto no Ken, license, name and exploding bodies restored and rebuilt in 3D, a Japan-only release that closed the circle.
