|This article is about a/an rider-like character in Kamen Rider Black.|
Shadow Moon is the alter ego of Nobuhiko Akizuki (秋月 信彦 Akizuki Nobuhiko), who had been abducted by Gorgom to become one of their new kings. Shadow Moon is both the stepbrother and best friend to Kohtaro Minami, who had been abducted alongside Nobuhiko but managed to escape.
Like Kamen Rider Black, Shadow Moon utilizes the King Stone to transform and is armed with the Satan Saber, a sword crafted specifically to be used by the Century Kings. When he first fought directly against Kohtaro and began losing, Shadow Moon temporarily turned back into Nobuhiko (due to the Creation King's interference) which sadly lasted for a few seconds before said procedure was reversed. He then attacked Kohtaro in cold blood and defeated him. As he seemingly hesitated to land the finishing blow to Kohtaro, he tightly gripped his Satan Saber and killed him. He was then ordered by the Creation King to take Kohtaro's King Stone and was slowly about to when Kohtaro turned back into his human form. The human form of Kohtaro seemingly caused Nobuhiko's humanity to slightly reawaken as he said Kohtaro's name once more and caused him to not only hesitate but also decide against taking Kohtaro's King Stone. As he proclaimed that he didn't require Kohtaro's King Stone to become the next Creation King, he was then questioned by the Creation King who asked if he regained his humanity upon temporarily reverting back to human form. Despite denying these accusations, Shadow Moon himself stated that he couldn't do it before disappearing away.
After having a rematch with a resurrected Kohtaro, he was weakened by Kamen Rider Black using the Satan Saber to slash the Kingstone. After being defeated, Shadow Moon then harshly told Kohtaro that he shall feel regret for the rest of his life knowing that he killed his best friend Nobuhiko and stated that he was the next Creation King. Despite saying such a cruel thing to Kohtaro, Shadow Moon was told to stay alive as Kohtaro promised he would save him. His last known words in this series were Black Sun.. Minami Kohtaro". He was left inside (due to the place exploding) the Gorgom Headquarters when his Kingstone exploded.
6 months later, he mysteriously resurfaced to seek revenge against his step brother. This time, he wielded the twin Shadow Sabers, similar to the original Satan Saber, gained from his King Stone. He was also also somewhat rusted in his initial appearance. He was finally defeated by RX when he thrusts the Revolcane through Shadow Moon's Kingstone. He then admits defeat and tells Kohtaro of the Crisis Empire's plans to erupt a volcano and tells him to stop said plans while he saves the children that were being held hostage. As Kohtaro then sees Nobuhiko as Shadow Moon and cries out his name, Nobuhiko claims that he is Shadow Moon who will be revived to fight Kohtaro once more. He then tells Kohtaro to go as he saves the kids and later peacefully dies on a bed of flowers. As the children question his death, Kohtaro assures them that he was resting as the kids go back to their father. Kohtaro then decided that in the end, Shadow Moon truly turned back into Nobuhiko as he carries his lifeless body to presumably bury him. While it was unknown if Shadow Moon truly turned back into Nobuhiko, it was shown that his corpse turned back into human form thus hinting so.
Kohtaro Minami is walking out when all of a sudden he finds himself out in the open under the moonlight and he sees someone floating around. It’s Black RX, only white. The Rider itself fights him and pulls his King Stone out and becomes the Creation King, Another Shadow Moon. The place turns into some dark temple with a throne and Shadow Moon sits down in it. Kohtaro yells but Shadow Moon sneers at him and as he removes his chest armour to reveal that inside is Nobuhiko's skeleton… and a beating heart. The fight between Black Sun and Shadow Moon was to determine which body would be most suitable for Gorgom's ruler, the Creation King to use. He ended up in Shadow Moon’s body. When things started to seem bleak, Nobuhiko's remaining thoughts prevented the Creation King from using it's full power as Kohtaro turns into RX by retrieving his King Stone and defeats Shadow Moon. Kohtaro then wakes up, apparently that was all a dream.
Kamen Rider World
However, Shadow Moon would return once again as a villain in the debatedly non-canon 8-minute movie Kamen Rider World. This time, he was a giant and he was defeated by Kamen Rider J's Jumbo Formation.

Kamen Rider SD
- Main article: Shadow Moon (SD)
Shadow Moon: A member of GranShocker. The brother of Black RX and apparently a Kamen Rider himself. This version of Shadow Moon tries his best to be evil, but falls short of his own expectations. He is armed with the Satan Sabre and an unknown motorcycle (possibly a Road Sector modification). He is constantly teased by Black RX, whom refers to him as "Sunshine Moon."
In other media
Shadow Moon is one of the few villains in the Kamen Rider Series to be given an action figure, Souchaku Henshin figure, and a Super Imaginive Chogokin figure. He is also one of the few Kamen Rider villains to have a Rider Kick, without being a Kamen Rider himself.
Shadow Moon was also featured as the first Secret Rare card in the Rangers Strike Masked Rider Expansion Vol. 1 and the only character in the Dark Alliance group in the Masked Rider Expansion Vol. 1.
An alternate reality version of Shadow Moon appeared in the film Kamen Rider Decade: All Riders vs. Dai-Shocker.
Video game appearances
Kamen Rider Black: Taiketsu Shadow Moon
Shadow Moon is the ninteenth opponent and seventh and final boss fought by Kamen Rider Black in the video game Kamen Rider Black: Taiketsu Shadow Moon.
Kamen Rider: Seigi no Keifu
In Kamen Rider: Seigi no Keifu, Shadow Moon appears to save Kamen Rider Black from Evil Eye when the latter tries to claim Black's Kingstone. When Black asks why he did this, Shadow Moon simply explains that it is because only he will defeat him and claim the title of Century King. Shadow Moon is then captured by Evil Eye and taken away so the monster can take his Kingstone instead.
Before he became Shadow Moon, Nobuhiko was a kind man whom Kohtaro respected and cared about. After becoming Shadow Moon, Nobuhiko became a cold, merciless man who was obsessed with defeating Kamen Rider Black and becoming the new Creation King. This was reflected by his seeming inability to revert to human form by himself. This sudden personality change would continue in RX until Kohtaro seemingly finally reverts him back to normal. He then somewhat redeems himself by saving some children before dying a peaceful death. Interestingly, it was hinted in a dialogue with Kamen Rider Double in the game All Kamen Rider: Rider Generation that even as Shadow Moon, there was still something left of Nobuhiko since he tells Philip and Shotaro to warn Kohtaro about Juda. This was also hinted in Black`s series as he seemed to slightly care for his sister and former girlfriend as well as stating Kohtaro by his name a number of times. Arguably though, this side was best shown when he hesitated and decided against taking Kohtaro's King Stone when he had the chance, despite his orders being to take both King Stones to become the next Creation King.
During his hibernation state in a circular pupa, Nobuhiko completely transformed into this grasshopper themed monster called the Batta Man (バッタ男 Grasshopper Man) before he became Shadow Moon.
Century King Shadow Moon is Nobuhiko's alter-ego after being brainwashed by Gorgom. Shadow Moon has roughly the same amount of power and strength as Kamen Rider Black. His primary techniques are the Shadow Punch and the Shadow Kick.

In the film Kamen Rider World, Shadow Moon is resurrected as a giant and uses his dark powers to revive five monsters destroyed by Kamen Rider Black, ZO and J. How he became a giant and returned from the dead is unknown, but it could possibly be a result of his King Stone absorbing J Power energy in his deceased state to resurrect him.

Behind the scenes
Shadow Moon is always with a debatable status of being a "Kamen Rider" or just a "Kamen Rider lookalike villain". One of the instances where Shadow Moon is referred to as a Kamen Rider, from the Summer 2013 issue of THE Kamen Rider magazine published by Shogakukan. However, in the 2014 magazine Our Kamen Rider Monster Ranking published by Takarajimasha, Shadow Moon is a candidate of the "rank 1" series' Monster.
- If Shadow Moon were to become a Kamen Rider, his name would presumably be "Kamen Rider Shadow" as Kamen Rider Black's Century King name is "Black Sun" although in theory it could also be "Kamen Rider White" which would serve as a parallel to Kohtaro's Rider Form.
- This is shown in the S.I.C Hero story for RX, as he is known as "White RX" in it.
- Interestingly enough, when Shadow Moon originally died, he somewhat hinted his return which eventually happened in the sequels.
- Interestingly, when Nobuhiko was temporarily turned back into human form, he seemed to have also regained his humanity as he smiled and called Kohtaro by his name.
- While it was hinted in his original death that Shadow Moon turned back into Nobuhiko in the end, later sequels imply that Nobuhiko still remained as Shadow Moon since he still sides with villains and not the protagonists. It is possible, though, that the Shadow Moons that appeared in later crossovers may have been either copies or alternate reality versions, especially with the appearance of an A.R. World counterpart in Kamen Rider Decade: All Riders vs. Dai-Shocker.
- Although it seemed that he still retained his memory as Nobuhiko, it was later stated in RX's series that had forgotten by then. This could explain why he wasn't as hesitant at defeating Kohtaro as the previous series.
- Stephen is his Filipino dub name.
