The '''Moon''' ({{Ruby|月|つき}} ''Tsuki'') is the [[Earth (planet)|Earth]]'s only natural satellite. It appears in every ''[[Yu-Gi-Oh!]]'' series, and in addition to appearing on many cards, the Moon plays an important role in ''[[Yu-Gi-Oh! ZEXAL]]'' and ''[[Yu-Gi-Oh! SEVENS]]''.

In ''[[Yu-Gi-Oh! ZEXAL]]'', the Moon was created when the [[Numeron Dragon]], who created the universe, shed a tear that impacted [[Earth]], and it became the location of the key to the [[Numeron Code]]. The Numeron Dragon borrowed the power of the "[[Number]]s" to create a spell to seal its power and tablets detailing a legend that could unlock its power in the form of a "Number", the [[Legend of the Dragons of Light and Time]].<ref name="zx133">{{episode|zexalZEXAL|133|ref}}</ref>

[[Kite Tenjo]], the holder of the Dragon of Light, "[[Galaxy-Eyes Photon Dragon (anime)|Galaxy-Eyes Photon Dragon]]", found another tablet inscribed with the legend at [[Jinlon]]'s [[Number ruins]] and resolved to travel to the Moon to battle [[Mizar]], the holder of the Dragon of Time, "[[Number 107: Galaxy-Eyes Tachyon Dragon (anime)| Number 107: Galaxy-Eyes Tachyon Dragon]]". After the [[Barian Emperor Onslaught]] began, Kite and [[Orbital 7]] used a spaceship to travel to the Moon, and once they arrived, the power of "Galaxy-Eyes Photon Dragon" caused the tablets detailing the Legend of the Dragons of Light and Time to appear, destroying Kite's shuttle and forcing him to use Orbital 7 as a spacesuit. Mizar followed Kite to settle their rivalry, and Kite explained the legend to him before they began their final Duel.<ref name="zx133" />

During the Duel, Kite evolved "Galaxy-Eyes Photon Dragon" into "[[Number 62: Galaxy-Eyes Prime Photon Dragon (anime)|Number 62: Galaxy-Eyes Prime Photon Dragon]]" using the power of the tablets. He also forced "[[Number C107: Neo Galaxy-Eyes Tachyon Dragon (anime)| Number C107: Neo Galaxy-Eyes Tachyon Dragon]]" to battle "[[Number 46: Dragluon (anime)| Number 46: Dragluon]]", restoring Mizar's true memories of his past.<ref>{{episode|zexalZEXAL|134|ref}}</ref> Kite defeated Mizar with "Prime Photon Dragon", but the damage of the Duel had damaged Orbital 7 and Kite's life support systems. "[[Number 100: Numeron Dragon (anime)| Number 100: Numeron Dragon]]" was released to Kite after the Duel, and he gave the card to Mizar before expiring on the Moon's surface from lack of air.<ref>{{episode|zexalZEXAL|135|ref}}</ref>

In the manga version of ''[[Yu-Gi-Oh! ZEXAL (manga)|Yu-Gi-Oh! ZEXAL]]'', [[Luna (ZEXAL)|Luna]] introduced herself to [[Ryoga Kamishiro (manga)|Shark]] as "a messenger from the moon", although what this actually meant was never explained.<ref>{{chapter|zexalZEXAL|19|ref}}</ref>

In ''[[Yu-Gi-Oh! ARC-V]]'', [[Leo Akaba]] attempted to channel the power of flowers, birds, the wind, and the Moon (the four beauties of nature in Japanese tradition) in order to obtain a way to stop [[Z-ARC]]'s rampage in the [[Original Dimension]], which resulted in the creation of the [[Four Nature Cards]], including "[[En Moon]]". His daughter [[Ray Akaba|Ray]] took the cards to prevent him from sacrificing himself, and played them in a Duel against Z-ARC, which caused the four powers to split each of them into four [[dimensional counterparts]] and space-time itself into [[Four Dimensions]].<ref>{{episode|arcvARC-V|127|ref}}</ref>

After Z-ARC revived himself by merging his four counterparts, Leo recreated the Nature Cards through the [[ARC-V Reactor]] and attempted to use them once more, but Z-ARC defeated him before he could do so.<ref>{{episode|arcvARC-V|139|ref}}</ref> [[Riley Akaba]], carrying Ray's soul, later joined the Duel and managed to activate the cards, with "En Moon" calling the power of the Moon again to neutralize the [[Fusion Monster]]s "[[Supreme King Z-ARC (anime)|Supreme King Z-ARC]]" and "[[Supreme King Dragon Starving Venom (anime)|Supreme King Dragon Starving Venom]]" by [[Negate|negating]] their [[effect]]s and turning them into [[Normal Monster]]s.<ref>{{episode|arcvARC-V|140|ref}}</ref>

In ''[[Yu-Gi-Oh! SEVENS]]'', the Moon is of great thematic importance. The urban legend of the [[King of Games|King of Duels]] states that when the Moon is full enough to be hardly recognizable, a Duelist will carve open a new path and guide the world as the King of Duels.<ref>{{episode|sevensSEVENS|1|ref}}</ref> The Moon also serves as the location for the [[Goha Duel Server]], where the data for Goha Dueling and [[Yu-Gi-Oh! Rush Duel|Rush Dueling]] is stored analogically by carving it into the lunar surface.<ref>{{episode|sevensSEVENS|51|ref}}</ref> [[Goha Space Elementary]] was constructed in Lunar orbit to allow the [[Goha SiblingsSix]] to monitor the Goha Duel Server.<ref>{{episode|sevensSEVENS|81|ref}}</ref>

The Moon also plays a large role in the story of the ''[[SEVENS (book)|SEVENS]]'' storybook, which is where [[Otes]] appears to have derived the legend of the King of Duels from. In it a young magician is tasked by an old wizard with gathering the "Sevens" to battle the Lord of Chaos who lives on the Moon, but the "Sevens" who represent the six [[Attribute|elements]] all fall in battle and the Lord of Chaos is revealed to be the old wizard, having manipulated the magician into destroying the six elements and claiming the Moon was the last thing to be destroyed to save a world in turmoil, an act the magician tearfully carried out. Otes re-enacts these events in the real world in his plan to destroy Dueling itself.<ref>{{episode|sevensSEVENS|88|ref}}</ref>

[[Yuga Ohdo]] and Otes' final Rush Duel takes place in orbit around the Moon, aboard the [[Super Rush Robot]] and the [[Otes Robot]] respectively, as Yuga attempts to stop extra Dueling formats being installed on the Goha Duel Server from overloading and destroying it.<ref>{{episode|sevensSEVENS|90|ref}}</ref> During the Rush Duel, Otes' servants attempted to attack the Super Rush Robot by uninstalling their Dueling formats and subsequently ejecting the constructs containing their data from the Goha Duel Server in the direction of the Super Rush Robot, though they were largely thwarted by Yuga's friends on Earth doing the same and [[Konvoy Sagawa]]'s construct was stopped by the Goha Siblings aboard [[Super Mobile Fortress SixrossStar Six]]. As Otes appeared to defeat Yuga, the Duel was interrupted by his servants believing it was time to clock out and they flew the Otes Robot to the dark side of the moon, pausing the Rush Duel due to being out of communication range.<ref>{{episode|sevensSEVENS|91|ref}}</ref> The Goha Duel Server's governance could not reach the far side of the moon, allowing Yuga to continue his Rush Duel with Otes despite not having his [[Duel ID card]], which he had rewritten into an extra copy of "[[Sevens Road Magician (anime)|Sevens Road Magician]]" to defeat [[Lucidien Kallister|Luke]]. Yuga successfully declared the final attack, but was forced to take both robots to lightspeed to avoid being disqualified when they re-entered the range of the Goha Duel Server. The sight of Yuga wearing the Goha Siblings' tiaras as a crown to control the Super Rush Robot and the full moon caused his friends to recall the legend of the King of Duels, declaring Yuga the true King of Duels.<ref>{{episode|sevensSEVENS|92|ref}}</ref> == Moon-related cards =={{Incomplete|list}}The following is a list of ''Yu-Gi-Oh!'' cards whose name, design, and/or overall concept directly references the Moon. {{Decklist|Moon cards|normal monsters = * [[Crying Moon Rabbit]]* [[LaMoon]]* [[LaMoon the Party Princess]]* [[Lunar Queen Elzaim]]* [[Maiden of the Moonlight]]* [[Mikazukinoyaiba]]* [[Moon Envoy]]|effect monsters = * [[Adularia of the June Moon]]* [[Arcana Force XVIII - The Moon]]* [[Flower Cardian Zebra Grass with Moon]]* [[Kimeluna the Dark Shifter]]* [[Magical King Moonstar]]* [[Mikazukinoyaiba, the Moon Fang Dragon]]* [[Millenniumoon Maiden]]* [[Moon Gardna]]* [[Moon Magician]]* [[Moonlit Papillon]]* [[Lunalight Black Sheep]]* [[Lunalight Blue Cat]]* [[Lunalight Crimson Fox]]* [[Lunalight Emerald Bird]]* [[Lunalight Kaleido Chick]]* [[Lunalight Purple Butterfly]]* [[Lunalight White Rabbit]]* [[Lunalight Yellow Marten]]* [[Penumbral Soldier Lady]]* [[Radius, the Half-Moon Dragon]]* [[Red-Eyes Moon Dragon]]* [[Seleglare the Luminous Lunar Dragon]]* [[Yamiluna the Dark Supporter]]|pendulum monsters = * [[Lunalight Tiger]]* [[Lunalight Wolf]]* [[PenduLuMoon]]|fusion monsters = * [[Kengo Shogun of the Crescent Moon]]* [[Kimeterasu the Rising Luna]]* [[Full Moon Dragon Umbralancer F]]* [[Lunalight Cat Dancer]]* [[Lunalight Leo Dancer]]* [[Lunalight Panther Dancer]]* [[Lunalight Sabre Dancer]]* [[Penumbral Keeper]]|synchro monsters = * [[Flower Cardian Moonflowerviewing]]* [[Moon Dragon Quilla]]* [[Vagnawa the Moon-Eating Dragon]]|xyz monsters = * [[Number 87: Queen of the Night]]|link monsters = * [[Moon of the Closed Sky]]* [[Protector of The Agents - Moon]]|normal spells = * [[Luna Light Perfume]]* [[Lunalight Fusion]]* [[Rising Luna Radiant Luster]]* [[Ultimate Slayer]]|equip spells = * [[Kahyoreigetsu]]* [[Mystical Moon]]* [[Moon Mirror Shield]]|continuous spells = * [[Attack the Moon!]]|quick-play spells = * [[Book of Lunar Eclipse]]* [[Book of Moon]]* [[Light Wing Shield]]* [[Sol and Luna]]|normal traps = * [[Lunalight Reincarnation Dance]]|continuous traps = * [[Lunalight Serenade Dance]]* [[Moon Dance Ritual]]|tokens = * [[Lunalight Token]]* [[Moon Token]]}}

* The Moon is one of the [[Guardian Star]]s in ''[[Yu-Gi-Oh! Forbidden Memories]]'', representing the [[Demon Magic Fiend (Alignment)|Demon MagicFiend]] [[Alignment]] of the original manga and other early ''Yu-Gi-Oh!'' video games (itself equivalent to the [[Fiend]] [[Type]] of the ''[[TCG]]''/''[[OCG]]'' and later other media).
