Century King Shadow Moon (世紀王シャドームーン)

Century King Shadow Moon (世紀王シャドームーン,Seiki Ō Shadō Mūn) is a fictional character who serves as the primary antagonist in the Japanese tokusatsu drama Kamen Rider BLACK

Ryuichi Oura As  Nobuhiko Tsukikage
 Nobuhiko Tsukikage (月影 ノブヒコ Tsukikage Nobuhiko^?) also known as Shadow Moon (シャドームーン Shadō Mūn^?) was an alternate reality version of the original Shadow Moon of Kamen Rider BLACK. Unlike the original Nobuhiko, this Shadow Moon had no known relation to the alternate reality Minami Kotaro. Nobuhiko was a butler who took care of Sayo, Tsukasa Kadoya's sister and convinced her to become High Priestess Bishium as part of his plan to take over Great Shocker. Once Tsukasa was ousted as leader, Nobuhiko took over as great leader.
After the return of all the Riders, Nobuhiko, as Shadow Moon stepped in to fight Kamen Riders Decade and Kuuga Rising Ultimate Form personally. Thanks to the intervention of a passing-through Kamen Rider Double, Shadow Moon was slammed into a wall of the Great Shocker tower, before being defeated by an All-Rider-Kick.
It is interesting to note that "Tsukikage" means "Moon Shadow."
