==How to A '''Fusion Summon==To Fusion Summon using "Polymerization" you must have the ''' (Japanese OCG: {{Ruby|融|ゆう}}{{Ruby|合|ごう}}{{Ruby|召|しょう}}{{Ruby|喚|かん}} ''Yūgō Shōkan''; Japanese [[Fusion Material MonsterRush Duel]]s listed on : フュージョン{{Ruby|召|しょう}}{{Ruby|喚|かん}} ''Fyūjon Shōkan'') is the Fusion Monster in your standard method for [[handSpecial Summon]] or on your side of the ing a [[Playing Field|fieldFusion Monster]]. You must then [[activate]] "Polymerization", select from the Fusion Monster from your [[Extra Deck]], . It requires a card effect to combine 2 or more monsters as [[send]] the Fusion Materials to the [[GraveyardMaterial]] and Fusion Summon the monster to your side of the field.

For example, to ==Mechanics==A Fusion Summon "can only be performed by a [[Flame Swordsmaneffect|card effect]]. Card effects that Fusion Summon first require the player to " using "Polymerization" you must have use"appropriate monsters as [[Fusion Material]]s listed on a Fusion Monster by moving them from some location(s) to another, then after that Fusion Summon the Fusion Monster from the [[Extra Deck]] [[Flame Manipulatorface-up]]" and "to an unoccupied [[Masaki the Legendary SwordsmanMain Monster Zone|Main]]" (the Fusion Materials) on either on your side of the field and/or in your hand. You then [[activateExtra Monster Zone]] "Polymerization", select "Flame Swordsman" from your Extra Deck, send "Masaki the Legendary Swordsman" and "Flame Manipulator" to the Graveyard and Fusion Summon "Flame Swordsman".

==Advanced rulings==If a [[Monster Card|monster]] is [[Special Summon]]ed from your [[Extra Deck]] by a [[card When an effect]] it is not treated as a to Fusion Summonresolves, unless stated on if the cardrequired Fusion Materials cannot be used or the Fusion Monster cannot be Fusion Summoned, no Fusion Summon occurs, nor are any Fusion Materials moved. For example , if the activating player cannot Special Summoning a monster from your Extra Deck using Summon when "[[Cyber-Stein]]Polymerization" is not considered a resolves, no monsters are sent to the Graveyard as Fusion SummonMaterial.

NormallyEven if all of a player's Monster Zones are occupied, a Fusion Monsters cannot Monster can still be Special Fusion Summoned from as long as at least one of the [[Graveyard]] or [[Banished Zone]] unless they were properly monsters in these zones is used as Fusion Material, so that there is an available zone when the Fusion Monster is Summoned before being sent. You cannot use "[[Re-Otherwise, if there is no room to Fusion]]" to [[revive]] Summon a monster when a Fusion Monster that has been Special Summoned using "Cyber-Stein" or sent to Summoning effect resolves, the Graveyard by "[[Fusion Guard]]". Fusion Summoned Monsters can be revived using cards such as "Re-Fusion" unless stated otherwiseSummon is not performed.

==Alternate methods==Other than using "[[PolymerizationFace-down]]", cards monsters on the field can be used as Fusion Summoned using any of Materials, as long as they are controlled by the following cards. Be sure to follow player performing the instructions on Fusion Summon and the card to Fusion performing the Summon the monster correctlyallows it.<ref name="Perfect Rulebook p72">{{cite book |author=Konami |title=Yu-Gi-Oh!

: ''See list [[===Fusion Summoning effect variations===As Fusion Summons]]are always performed by card effects, the specific actions involved in Fusion Summoning are exclusively determined by the individual effects that do so, meaning that their details can vary significantly.''

==* Cards of all card types can have Fusion Substitute Monsters==: ''See main article Summoning effects. For example, "[[D/D Swirl Slime]]" ([[Monster Card]]), "[[Polymerization]]" ([[Spell Card]]), "[[Necro Fusion Substitute Monsters]]" ([[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. 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)** "[[Parallel World Fusion]]" (shuffles banished monsters into the Deck as material)** "[[Brilliant Fusion]]" (uses monsters in the Deck as material)** "[[Odd-Eyes 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. Examples:** "[[Magistus Invocation]]" (can use Monster Cards treated as [[Equip Card]]s as material)** "[[Pendulum Fusion]]" (can use [[Pendulum Monster]]s in the [[Pendulum Zone]]s as material)** "[[Vision Fusion]]" (can use Monster Cards treated as [[Continuous Trap]]s as material) * Fusion Summoning effects can perform particular actions on materials beyond simply moving them. 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 Monster being 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]</ref> ===Interactions with effects=In the anime==In * 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]]", "[[Chain Material]]").* [[Fusion Substitute Monster]]s can be used in Fusion Summoning effects in place of a material with specified conditions that the second season 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.** 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. ===Treating a Special Summon as a Fusion Summon==={{main|Treats Special Summon as Fusion Summon}}Some card effects can Special Summon a Fusion Monster, treating that Special Summon as a Fusion Summon. 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 Summon. ==Example=={{Show card image gallery| Polymerization | "[[Polymerization]]"| Dark Magician | + A [[Fusion Material]]<br />("[[Dark Magician]]")| Buster Blader | + A [[Fusion Material]]<br />("[[Buster Blader]]")| Dark Paladin | {{=}} A [[Fusion Monster]]<br />("[[Dark Paladin]]")}} ==Rush Duel==In ''[[Yu-Gi-Oh! Rush Duel]]'', the main card for Fusion Summoning is "[[Fusion (second series animeRush Duel)|Fusion]]". "Fusion" can only use face-up monsters from the controller's field as Fusion Materials. "[[Polymerization (Rush Duel)|Polymerization]]" and "[[Power Bond (Rush Duel)|Power Bond]]" are also available as [[Legend Card]]s, and other Spells, Traps and monster effects that can perform Fusion Summons have subsequently been added. ==Appearance=====Anime=======''Yu-Gi-Oh!'' second , ''GX'', ''5D's'', and ''ZEXAL''====Visual depictions of Fusion Summons have varied significantly among the first four anime series anime]]. Typically, the 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, it is stated that notably used for "[[Fusion MonsterDark Paladin]]s cannot " and "[[attackDragon Knight Draco-Equiste]] ", shows the same 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. ====''Yu-Gi-Oh! ARC-V''====In ''[[turnYu-Gi-Oh! ARC-V]] they are Summoned as part '', a standardized animation is adopted for all Fusion Summons: a blue and orange rotating background based on the artwork of "Polymerization", and the Fusion Materials transforming into featureless shapes of different colors (usually contrasting ones like blue and red, yellow and violet, etc.) that swirl together to form a spinning spiral, which then sometimes turns into a rule for Kaiba's Domino City Tournamentbright white light. This It is exemplified in then followed by a close-up shot of the player, usually clasping or clapping their hands together, as if mirroring the materials becoming one. In ''Yu-Gi-Oh! ARC-V'', a Fusion Summon performed using Fusion Materials that have been previously [[Pendulum Summon]]ed is referred to as a "Pendulum-Fusion". ====''Yu-Gi-Oh! VRAINS''====[[File:CynetFusion-JP-Anime- Episode 065VR-NC.png|thumb|right|episode 65A Fusion Summon in ''Yu-Gi-Oh! VRAINS'']], when In ''[[StringsYu-Gi-Oh! VRAINS]] uses "'', Fusion Summoning is changed to a different CGI effect, where the Fusion Materials transform into streams of colored particles that swirl together and then burst upwards into vortexes of colors matching the streams, which twist around each another and quickly merge into a large purple one, from where the Fusion Monster appears. ====''Yu-Gi-Oh! SEVENS'' and ''GO RUSH!!''====In ''[[Quick AttackYu-Gi-Oh! SEVENS]]" on "'' and ''[[Humanoid Worm DrakeYu-Gi-Oh! GO RUSH!!]]" '', the background is distorted with pink and blue ripples, visually somewhat similar to bypass that rule its appearance in his ''Yu-Gi-Oh! ARC-V''. The Duelist raises their [[DuelDisk]] against into the air, creating a "7" shape with their arm, and "[[Yami YugiFusion (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. This rule does not exist  ===Video games=======''Yu-Gi-Oh! Duel Links''====When most characters perform a Fusion Summon, an animation similar to the animation in the ''Yu-Gi-Oh! ARC-V'' anime is played. When a ''VRAINS'' character, or a [[OCGStandard Duelist]]/[[TCG]] and was phased out of in Duel World (VRAINS), performs a Fusion Summon, an animation based on the ''VRAINS'' anime for animation is played. ====''Yu-Gi-Oh! Master Duel''====The Fusion Summon animation in ''[[Yu-Gi-Oh! GXMaster Duel]]'' and is based on that from the ''[[Yu-Gi-Oh! 5D's' 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 is complete. The only exception is when "[[Super Polymerization (Master Duel)|Super Polymerization]]''" is used to perform the Fusion Summon, to which the yellow flash portal of "Super Polymerization" appears before the monsters were warped into the "Polymerization" 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 />
