A '''Fusion Summon''' (Japanese OCG: {{Ruby|融|ゆう}}{{Ruby|合|ごう}}{{Ruby|召|しょう}}{{Ruby|喚|かん}} ''Yūgō Shōkan''; Japanese [[Rush Duel]]: フュージョン{{Ruby|召|しょう}}{{Ruby|喚|かん}} ''Fyūjon Shōkan'') is the act of standard method for [[Special Summon]]ing a [[Fusion Monster]] from the [[Extra Deck]] using the effect of . It requires a card that states that it performs a effect to combine 2 or more monsters as [[Fusion SummonMaterial]].

==How to Fusion SummonMechanics==A player can Fusion Summon can only be performed by a Fusion Monster from the Extra Deck by [[activateeffect|activatingcard effect]] a card or effect . Card effects that performs a Fusion Summon. When that effect resolves, first require the player uses to "use" appropriate monsters as [[Fusion Material]]s listed on a Fusion Monster by moving them from some location(s) to another location, as specified by the effect performing the then after that Fusion Summon (usually [[send]]ing them to the [[Graveyard]] or [[banish]]ing them). After that, the player Summons the Fusion Monster from the [[Extra Deck]] [[face-up]] to an unoccupied [[Main Monster Zone]] that a [[Link Monster]] [[points to|Main]] or an [[Extra Monster Zone]] in [[face-up]] [[Attack Position|Attack]] or [[Defense Position]].

Prior to the introduction of the Most commonly, [[Performs a Fusion Summon|cards with effects that can Fusion Summon]] are [[Spell Card]]s (e.g. "[[Extra Monster ZonePolymerization]]"). These effects typically involve using monsters from the player'shand or field as Fusion Materials. If not otherwise specified in the card text, a monster could be monsters used as Fusion Summoned Material are [[sent]] to any the [[Monster ZoneGraveyard]].

Even When an effect to Fusion Summon resolves, if all appropriate Monster Zones are occupied, a the required Fusion Materials cannot be used or the Fusion Monster can still cannot be Fusion Summoned as long as at least one of the , no Fusion Summon occurs, nor are any Fusion Materials used is in one of these Zonesmoved. For example, so that there is an available Zone if the activating player cannot Special Summon when "Polymerization" resolves, no monsters are sent to the Graveyard as Fusion Monster is SummonedMaterial.

==List Even if all of cards a player's Monster Zones are occupied, a Fusion Monster can still be Fusion Summoned as long as at least one of the monsters in these zones is used as Fusion Material, so that there is an available zone when the Fusion Monster is Summoned. Otherwise, if there is no room to Fusion Summon=={{main|Performs a monster when a Fusion Summoning effect resolves, the Fusion Summon}}is not performed.

[[Face-down]] monsters on the field can be used as Fusion Materials, as long as they are controlled by the player performing the Fusion Summon and the card performing the Summon allows it.<ref name="Perfect Rulebook p72">{{cite book |author=ExampleKonami |title=Yu-Gi-Oh!

For example, "[[D/D Swirl Slime]]" ([[Monster Card]]), "[[Polymerization-SDMY-EN-C-1E]]" ([[Spell Card]]), "[[Necro Fusion]]" ([[Trap Card]]). * Fusion Summoning effects can use monsters from various locations as Fusion Materials, sometimes moving materials to different locations based on their original location.png | Examples:** "[[Super Polymerization]]"(uses monsters from either player's field as material)** "[[Miracle Fusion]]" (banishes monsters from the field or Graveyard as material)** "[[Cyberdark Impact!]]" (shuffles monsters from the hand, field, or Graveyard into the Deck as material)DarkMagician-LEDD-EN-C-1E.png | + A ** "[[Parallel World Fusion Material]]<br />" (shuffles banished monsters into the Deck as material)** "[[Dark MagicianBrilliant Fusion]]"(uses monsters in the Deck as material)BusterBlader** "[[Odd-SDMY-EN-C-1EEyes Fusion]]" (uses monsters in the [[Extra Deck]] as material)** "[[Ghost Fusion]]" (uses monsters from the field as material, but can also banish a monster from the hand, Deck, or Graveyard as material) * While normally only monsters (including Spell/Trap Cards treated as monsters) can be used as Fusion Materials, some card effects allow Monster Cards treated as Spell/Trap Cards to be used as Fusion Materials.png | + A Examples:** "[[Magistus Invocation]]" (can use Monster Cards treated as [[Equip Card]]s as material)** "[[Pendulum Fusion Material]]<br />" (can use [[Pendulum Monster]]s in the [[Pendulum Zone]]s as material)** "[[Buster BladerVision Fusion]]"(can use Monster Cards treated as [[Continuous Trap]]s as material)DarkPaladin-LEDD-EN-C-1E* Fusion Summoning effects can perform particular actions on materials beyond simply moving them.png | = A Examples:** "[[Rapid Trigger]]" (Fusion Summons by destroying Fusion Materials)** "[[Dark World Accession]]" (Fusion Summons by discarding Fusion Materials) * Fusion Summoning effects can entirely ignore the material requirements of the Fusion Monsterbeing Fusion Summoned. The sole example of such an effect is "[[The Eye of Timaeus]]", which Fusion Summons specifically using only 1 "[[Dark Magician (archetype)|Dark Magician]]" monster, even though all of its applicable targets require at least 2 monsters as materials.<ref>[https://www.db.yugioh-card.com/yugiohdb/faq_search.action?ope=5&fid=88&request_locale=ja Konami OCG Card Database: Ruling #88]<br /ref> ===Interactions with effects===* Some cards have effects that allow the player to use monsters from locations other than the ones specified in the Fusion Summoning effect as materials when Fusion Summoning (e.g. "[[Cybernetic Fusion Support]]", "[[Dark PaladinChain Material]]").* [[Fusion Substitute Monster]]s can be used in Fusion Summoning effects in place of a material with specified conditions that the Fusion Substitute Monsters inherently do not fulfill. Usually, they can substitute for a material with a specifically listed name, but "[[Shaddoll Core]]" can substitute for materials of certain [[Attribute]]s instead.</gallery>** Some Fusion Monsters have a condition that they [[Must be Fusion Summoned with listed Fusion Materials|must be Fusion Summoned with their listed Fusion Materials]], which prevents Fusion Substitute Monsters from substituting any of the Fusion Materials. However, this restriction only applies to Fusion Material substitution effects—it does not prevent using monsters whose names have been [[Changes card names|changed]] to or [[Treated as alternate name|treated]] as a different card name from being used as a material according to that name.

=== Example B: Using Treating a Special Summon as a Fusion Substitute Monsters Summon===<gallery mode=packed heights=250px>Polymerization-SDMY-EN-C-1E.png {{main| "[[Polymerization]]"Treats Special Summon as Fusion Summon}}KingoftheSwamp-FUEN-EN-SR-1E.png | + A [[Some card effects can Special Summon a Fusion Substitute Monster]]<br />("[[King of the Swamp]]", used in place of "[[Elemental HERO Flame Wingman]]")ElementalHEROSparkman-DEM2-EN-C-UE.png | + treating that Special Summon as a correct Fusion Material<br />("[[Elemental HERO Sparkman]]")ElementalHEROShiningFlareWingman-LCGX-EN-ScR-1ESummon.jpg | = A non-[[strict This type of Special Summon is not a Fusion Summon]] [[despite being treated as one, so it does not necessarily follow any mechanics of a Fusion Monster]]<br />("[[Elemental HERO Shining Flare Wingman]]")</gallery>Summon.

==EffectsRush Duel==Like other Extra Deck monstersIn ''[[Yu-Gi-Oh! Rush Duel]]'', if a the main card for Fusion Monster Summoning is not Fusion Summoned first, it cannot be "[[Special SummonFusion (Rush Duel)|Fusion]]ed ". "Fusion" can only use face-up monsters from the controller's field as Fusion Materials. "[[Polymerization (Rush Duel)|Polymerization]]" and "[[GraveyardPower Bond (Rush Duel)|Power Bond]] or while " are also available as [[banishLegend Card]]ed (unless it specifies another way to properly Special Summon its, and other Spells, in which case it must first be Summoned Traps and monster effects that way)can perform Fusion Summons have subsequently been added.

For example==Appearance=====Anime=======''Yu-Gi-Oh!'', ''GX'', ''5D's'', if a and ''ZEXAL''====Visual depictions of Fusion Monster is Special Summoned from Summons have varied significantly among the Extra Deck by first four anime series. Typically, the effect Fusion Materials, or their cards, are shown being warped into particles or forms of energy in a spiral direction, which then merge with each other within a spiraling portal, from which the Fusion Monster emerges. One depiction, notably used for "[[Cyber-SteinDark Paladin]]" and sent to the Graveyard, or was sent to the Graveyard by "[[Fusion GuardDragon Knight Draco-Equiste]]", it cannot be Special Summoned from shows the Graveyard by "[[Re-Fusion]]"; howeverMaterials being engulfed in a sphere of energy, if it was originally which then disperses to reveal the Fusion Summoned by "[[Polymerization]]"Monster. Other times, it can be Special Summoned from the Graveyard by "Re-Fusion"Monster emerges from a fierce whirlwind.

==In the anime==''Yu-Gi-Oh! ARC-V''====While visual depictions of Fusion Summons have varied significantly among the different anime series, most generally show the Fusion Materials, or their cards, being warped into particles or forms of energy in a spiral direction, which then merge with each other within a spiraling portal, from which the Fusion Monster emerges. It is not until In ''[[Yu-Gi-Oh! ARC-V]]'' where , a standardized version of this method animation is adopted for all Fusion Summons, with the portal consisting of : a blue and orange swirls of energy, referencing rotating background based on the artwork of "Polymerization", and the Fusion Material Monsters Materials transforming into differently colored forms featureless shapes of energy different colors (usually the colors being contrasting ones like blue/and red, yellow/and violet, etc.)that swirl together to form a spinning spiral, which then swirl together sometimes turns into a spiral before entering bright white light. It is then followed by a close-up shot of the portal. Fusion Summon practitioners player, usually clasp clasping or clapping their hands together at the moment the monsters combine, seemingly as if mirroring that the materials become becoming one.

Prior to In ''Yu-Gi-Oh! ARC-V'', another depiction of a Fusion Summon, notably used for "performed using Fusion Materials that have been previously [[Dark PaladinPendulum Summon]]ed is referred to as a " and "[[Dragon Knight DracoPendulum-Equiste]]Fusion", shows the Fusion Materials being engulfed in a sphere of energy, which then disperses to reveal the Fusion Monster. Other times, the Fusion Monster emerges from a fierce whirlwind.

In ''[[Yu-Gi-Oh! VRAINS]]'', Fusion Summoning is more visually elaborate. The changed to a different CGI effect, where the Fusion Materials transform into streams of colored particles similar in shape to the energy forms seen in ''ARC-V'', swirling that swirl together and then bursting burst upwards into multiple vortexes of colors matching the same color as the Fusion Materialsstreams, which twist around one each another and combine quickly merge into a large purple one, from which where the Fusion Monster appears. ====''Yu-Gi-Oh! SEVENS'' and ''GO RUSH!!''====In ''[[Yu-Gi-Oh! SEVENS]]'' and ''[[Yu-Gi-Oh! GO RUSH!!]]'', the background is distorted with pink and blue ripples, visually somewhat similar to its appearance in ''Yu-Gi-Oh! ARC-V''. The Duelist raises their [[Duel Disk]] into the air, creating a "7" shape with their arm, and "[[Fusion (Rush Duel)|Fusion]]" creates a "Road" from the Duelist's Duel Disk, then it shows the listed materials fuse by overlaying one over another, creating a large colored beam, the Fusion Monster is generated afterwards.

In the [[Yu-Gi-Oh! (anime)|===Video games=======''Yu-Gi-Oh!Duel Links'' anime]], under [[Battle City Rules]], which applied during the [[Battle City]] tournament, [[====When most characters perform a Fusion Monster]]s cannot [[attack]] the same [[turn]] they are Summoned. This is exemplified in [[Yu-Gi-Oh! - Episode 065|episode 65]]Summon, when [[Strings]] uses "[[Quick Attack]]" on "[[Humanoid Worm Drake]]" an animation similar to bypass that rule in his [[Duel]] against [[Yami Yugi]]. This rule does not exist the animation in the ''[[Yu-Gi-Oh! Official Card Game|OCG]]ARC-V'' anime is played. When a ''/VRAINS''character, or a [[Yu-Gi-Oh! Trading Card Game|TCGStandard Duelist]]in Duel World (VRAINS), performs a Fusion Summon, an animation based on the ''VRAINS'' and was removed for all subsequent seriesanime animation is played.

In ====''Yu-Gi-Oh! ARCMaster Duel''====The Fusion Summon animation in ''[[Yu-Gi-Oh! Master Duel]]'' is based on that from the ''Yu-Gi-VOh!''anime, with the materials being surrounded in a purple aura before they are warped into the "Polymerization" portal in a spiral; the Fusion Monster emerges from the spiral when the Summon performed using Fusion Materials that have been previously is complete. The only exception is when "[[Pendulum SummonSuper Polymerization (Master Duel)|Super Polymerization]]ed " is referred used to perform the Fusion Summon, to as a which the yellow flash portal of "Super Polymerization" appears before the monsters were warped into the "Pendulum-FusionPolymerization"portal.

* ==Trivia==In the ''[[Yu-Gi-Oh! (manga)|Yu-Gi-Oh!]]'' manga and [[Yu-Gi-Oh! (anime)|anime]], under [[Battle City Rules]], which applied during the [[Battle City]] tournament, [[Fusion MonstersMonster]]s cannot [[attack]]* the same [[turn]] they are Fusion Material MonstersSummoned. This is exemplified in [[Yu-Gi-Oh! - Episode 065|episode 65]]* , when [[Strings]] uses "[[Quick Attack]]" on "[[Humanoid Worm Drake]]" to bypass that rule in his [[Duel]] against [[Yami Yugi]]. It also applied during the ''[[Yu-Gi-Oh! R]]'' manga and the [[Fusion Substitute MonstersVirtual World (arc)|Virtual World]]* arc. This rule does not exist in the ''[[Fusion Deck ZoneYu-Gi-Oh! Official Card Game|OCG]]* ''/''[[Fusion DeckYu-Gi-Oh! Trading Card Game|TCG]]* '' and was removed from the anime starting with the ''[[Extra DeckWaking the Dragons]]'' arc and for all subsequent series. ==References==<references />
