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 Kohtaro Minami.
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 the organization, calling himself the Creation King.
After the return of all the Riders, Nobuhiko, as Shadow Moon stepped in to fight Kamen Riders Decade and Kuuga Rising Ultimate 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.
Nobuhiko appears to be a manipulative mastermind, having manipulated both Tsukasa and Sayo to take over Dai-Shocker in an effort to rule over the various Kamen Rider Worlds. Once his friendly facade drops, he shows his true colors as a cold-hearted killer, who would kill anyone who gets in his way.
