Nobuhiko Akizuki

is the adoptive brother and best friend to Kohtaro Minami, both being born on the same day during a solar eclipse. On the night of their 19th birthday, the two were abducted by Gorgom, being altered into candidates for the new Creation King. He transforms into and serves as a major antagonist in the Kamen Rider Series installment Kamen Rider Black and Kamen Rider Black RX.
==History==
===Black===
Despite their father trying his best to save both from Gorgom, only Kohtaro successfully escaped. Nobuhiko instead was heavily injured in the process and fell into a deep coma, under Gorgom's clutches. Later on in the series, the three high priests of Gorgom used their combined powers to forcibly reawaken Nobuhiko from his coma, at the cost of retaining their humanoid forms. Nobuhiko, having his mind altered alongside his body, was now Shadow Moon.
Like Kamen Rider Black, Shadow Moon utilizes the Kingstone to transform and is armed with the Satansaber, a sword crafted specifically to be used by the Century Kings. 
The two Century Kings eventually fought each other, both seemingly matched in strength. Despite Kohtaro's unwillingness to fight, he proved himself the more formidable warrior, slowly gaining the advantage in their battle.
Noticing this, the Creation King intervened in the battle, causing Kamen Rider Black's defeat. 
Pleased that Shadow Moon had won, the Creation King ordered him to take Kohtaro's Kingstone. Just when Shadow Moon had reached his hands toward it though, Kohtaro suddenly reverted back into his human form.
Shocked by this, Shadow Moon became hesitant. Even with High Priest Darom and the Creation King's urgings, Nobuhiko's remaining humanity prevented him from acquiring both Kingstones, instead retreating away.
Having a rematch with the resurrected Kohtaro later on, Shadow Moon was ultimately overwhelmed by him. Defeated, Shadow Moon spitefully told Kohtaro to feel regret knowing that he had murdered Nobuhiko by being the victor of their duel. Not wishing to lose his best friend, Kohtaro told Shadow Moon to stay alive while he fought the Creation King.
Mid-way in Kohtaro's battle with the Creation King, he called forth the Satansaber, realizing that it is the only weapon he could use to win. The Satansaber noticed Kohtaro's call for it, with Shadow Moon noticing as well. In what appeared to be his final act as Nobuhiko, Shadow Moon stated Kohtaro's full name and released his grasp on the Satansaber, allowing it to fly towards Kohtaro. With Kohtaro using the Satansaber to defeat the Creation King, Gorgom's base began self-destructing, Shadow Moon still being trapped inside.
===RX===
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 Satansaber, gained from his Kingstone. He was finally defeated by RX when he thrusts the Revolcane through Shadow Moon's Kingstone. Admitting defeat, Shadow Moon tells Kohtaro of the Crisis Empire's plans and proceeds to use his remaining strength to save two children that were being held hostage. Surprised by Shadow Moon's actions, Kohtaro suddenly sees Nobuhiko's image from him. While denying Kohtaro's cries to him as Nobuhiko, Shadow Moon still marched forward toward the hostages, all while urging Kohtaro to not waste time.
Trusting that Shadow Moon will save the children, Kohtaro then proceeds to stop Matbot from flooding the city with magma, before returning to Shadow Moon's location. There he sees the two children express their concern to their savior, who was on the ground on a bed of flowers. Assuring the two that Shadow Moon was merely sleeping from exhaustion, Kohtaro oversees them return to their father, before returning his attention to Shadow Moon.
Remembering Shadow Moon's last actions and Nobuhiko's kindness, Kohtaro questioned whether the image he had seen was just a mirage. Convinced otherwise, Kohtaro decided that his best friend had indeed regained his humanity in the end, overcoming Gorgom's corruption. Carrying Nobuhiko's body, Kohtaro then swore to not let his death be in vain, becoming even more determined to defeat the Crisis Empire. Notably, Nobuhiko is shown to have reverted back into human form after dying, signifying his release from being Shadow Moon.
===After 0===
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 Kingstone 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 Kingstone 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.
=== OOO, Den-O, All Riders: Let's Go Kamen Riders ===
Due to a change in history caused by Ankh leaving a O Medal behind in 1971, Shocker achieved its goal of world dominion with the Shocker Greeed which defeated the Double Riders, and new members from the various groups that would had manifested in the normal timeline after Shocker's destruction. Shadow Moon was among the many villains who were part of this alliance. He later is defeated by Kamen Rider Decade.

Once it is revealed that in fact it was Tsukasa and Captain Marvelous who were deceiving them to stop their plans, Shadow Moon joins the fight against the heroes just to be defeated along with General Jark by the combined efforts of Kamen Rider Black and the Hikari Sentai Maskman.

To be added
==Appearances in other media==
===Kamen Rider SD===
Shadow Moon: A member of Grand Shocker. 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 Satansaber and an unknown motorcycle (possibly a Road Sector modification). He is constantly teased by Black RX, whom refers to him as "Sunshine Moon."
==Video game appearances==
===Kamen Rider Black: Taiketsu Shadow Moon===
Shadow Moon is the nineteenth opponent and seventh and final boss fought by Kamen Rider Black in the video game Kamen Rider Black: Taiketsu Shadow Moon.
Instead of the usual look, he appears as a purple variation of Black after hatching from Batta Man.
===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.
===All Kamen Rider: Rider Generation===
Shadow Moon appears as a boss in the video game All Kamen Rider: Rider Generation.
Shadow Moon is the fourth major boss encountered in the storyline, being equipped with the Satan Saber. Referring to himself as the next Creation King, Shadow Moon proclaims his desire to obtain Black's Kingstone to his foes, stating that none shall stop him from doing so. Upon losing, Shadow Moon will tell his foes that he will await Black in their proper timeline, as well as warning them about Juda. 
If encountering Kohtaro Minami as either Black or Black RX, Shadow Moon will express his desire to fight him as fellow Century Kings, much to Kohtaro's sorrow. Once defeated, Shadow Moon will postpone their battle, with Kohtaro vowing to save him as Nobuhiko. Shadow Moon will then disappear while attempting to warn Kohtaro of Juda. 
If Kamen Rider Double is chosen by the player character to face Shadow Moon, Philip will first briefly explain to Shotaro of Nobuhiko and Kohtaro's predicament. After the battle, Shotaro expresses sadness for Shadow Moon's cruelty, with Philip deeming Nobuhiko to be completely lost. Once Shadow Moon tells them to warn Kohtaro about Juda though, Shotaro notices his lingering humanity, questioning it in response. Seemingly affected by Shotaro's words, Shadow Moon momentarily becomes silent, before stating his concern to be Kohtaro's Kingstone alone.
===Kamen Rider: Battride War Genesis===
Nobuhiko as Red Shadow Moon appears as a boss in Kamen Rider: Battride War Genesis. Through time travel, the Creation King stole Nobuhiko's corpse, using it as a vessel to rule the world. Once weakened by the Kamen Riders, the Creation King lost control over his new body, causing Shadow Moon to be resurrected. Absorbing the Creation King's essence, Shadow Moon gained the full powers of his predecessors, proclaiming himself the "new"Creation King. 
Facing Hongo Takeshi/Kamen Rider 1 and the others, Shadow Moon sneered at them, believing that they had no chance of victory. Ultimately though, Hongo and the others prevailed, much to Shadow Moon's shock. Recieving several Rider Kicks in conjunction, Shadow Moon explodes in the end. 
===Miscellaneous===
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 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.
== Personality ==
Before he became Shadow Moon, Nobuhiko was a kind man whom Kohtaro respected and cared about. After his transformation though, Nobuhiko became an arrogant, cold, and merciless tyrant that was obsessed with defeating Kamen Rider Black and becoming the new Creation King. Even with Nobuhiko's memories intact, he showed no concern for humanity, believing that Gorgom had every right to rule mankind. This was reflected by his inability to revert to human form on his own, requiring the Creation King's assistance. 
However, despite Gorgom's corruption, Shadow Moon still retained a portion of his humanity. His concern towards Kyoko and Katsumi has been shown several times, actively saving the former from High Priestess Bishum on one occasion. Furthermore, when given the chance to take away Kohtaro's Kingstone at one point, Shadow Moon outright relented the opportunity, proclaiming that he could not bring himself to do it. 
When reappearing in Kamen Rider RX, Shadow Moon seemed to have lost all traces of his humanity. The extreme conditions he had to endure to cheat death removed his memories as Nobuhiko, causing him become even more ruthless towards Kohtaro. Upon his final defeat however, Shadow Moon appeared to have a change of heart, opting to help Kohtaro rather than continue fighting him. Kohtaro himself acknowledges this, believing that Nobuhiko had finally regained his kindness in the end. 
== Powers and abilities ==
* Superhuman Physiology: As the Century King Shadow Moon, Nobuhiko's overall physical capabilities exceed Gorgom's followers, being far above them in strength. Potentially, Shadow Moon is able to become stronger than the godlike Creation King, given his role as intended successor.
* Mystical Powers: Shadow Moon has an array of mystical powers at his disposal, being able to teleport, create energy beams, possess others, summon the Satan Saber, and even cheat death. 
* Temporal Protection: Theoretically, Shadow Moon's Kingstone makes him immune to changes in the timeline. [The Dangerous Time Thief]

==Behind the Scenes==
===Portrayal===
Nobuhiko Akizuki is portrayed by while Shadow Moon is voiced by .
==Debatable Status==
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.https://twitter.com/kumo_2099/status/924260701106925569 However, in the 2014 magazine Our Kamen Rider Monster Ranking published by Takarajimasha, Shadow Moon is a candidate of the "rank 1" series' Monster. Additionally, the Kamen Ride: Shadow Moon card lacks the 'Masked Rider' title all the other Kamen Ride cards possess, barring that of Skyrider due to his unique naming status.
During the All Kamen Rider Great Voting in 2021, Shadow Moon was listed as a Kamen Rider.
The incarnation of Nobuhiko Akizuki which appears in the Kamen Rider Black Sun reboot would be referred to as Kamen Rider Shadowmoon, marking the first instance of a character named Shadow Moon to be irrefutably referred to as such.

==Notes==
*If real world events are applied in the story, Nobuhiko and Kotaro's birthday is most likely on September 22, 1968, as they turn 19 in 1987, while in 1968, there was one Solar eclipse occurring on September 22.
*Despite Shadow Moon having regained his humanity as Nobuhiko upon dying in Kamen Rider Black RX, later sequels ignore this altogether. It is possible though, that the Shadow Moons that appear in later crossovers are either copies or alternate reality versions of the original, especially with the appearance of an A.R. World counterpart in Kamen Rider Decade: All Riders vs. Dai-Shocker.
*Stephen is Nobuhiko's Filipino dub name.
