Kamen Rider Black : Taiketsu Shadow Moon

Kamen Rider Black: Taiketsu Shadow Moon is a side-scrolling action game for Nintendo's Family Computer Disk System, released in Japan by Bandai on April 15, 1988. Developed by Human Entertainment, it adapts the then-current Kamen Rider Black television series rather than telling an unrelated take on the property. Its Japanese title means Kamen Rider Black: Showdown with Shadow Moon, framing the game around the rivalry at the center of the show's story.

Players control Kotaro Minami in his Kamen Rider Black identity as he battles Gorgom's mutant forces. The premise follows the series' basic conflict: Kotaro escaped Gorgom's attempt to turn him into one of its chosen cyborg leaders and fights the organization while trying to save his stepbrother Nobuhiko Akizuki. Nobuhiko becomes the silver-armored Shadow Moon, making the final confrontation a dramatic meeting between former brothers and rival Century Kings rather than just another monster battle.

The main stages use a horizontal, left-to-right action format. Black advances on foot through enemy-filled areas, defeating Gorgom creatures and working toward a boss encounter. The game is structured into five larger levels, with the first four divided into four stages. In each of those early levels, three standard side-scrolling sections build toward a fourth stage that changes the presentation for a larger, more focused boss fight.

Battle Hopper, Black's motorcycle from the television program, is incorporated into the action instead of serving only as a visual reference. Riders can use the machine during the second and fourth levels, giving those sections a different pace from the on-foot combat. Its presence links the Famicom Disk System game closely to the hero's screen identity, where the bike is one of Black's most recognizable supporting machines.

The campaign saves its heaviest concentration of opponents for the fifth level. Rather than presenting another sequence of exploratory scrolling stages, it becomes a series of boss confrontations. Black must first overcome Gorgom's three Evil Lords before reaching Shadow Moon. This escalation mirrors the source material's move from recurring mutant threats toward the larger conflict surrounding Gorgom and the successor to its Creation King.

Shadow Moon is especially important to the adaptation because he is not simply a villain invented for the game. In the 1987-1988 Kamen Rider Black series, he is Nobuhiko, Kotaro's kidnapped stepbrother and the other candidate selected by Gorgom. The television series builds its story around their forced opposition, while the game makes that relationship the endpoint of its action campaign. Losing the final battle triggers a bad ending, reinforcing the importance of the showdown.

Taiketsu Shadow Moon arrived while Kamen Rider Black was still on television, whose original Japanese run began in October 1987 and ended in October 1988. That timing makes the game a period piece of the franchise's late-Showa-era popularity: a licensed Disk System action title designed around the series' hero, enemies, motorcycle, and most consequential rival. For retro Kamen Rider fans, it is a direct early game adaptation of Black's struggle against Gorgom and Shadow Moon.
