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 . It requires a card effect of "[[Polymerization]]" to combine 2 or any other more monsters as [[card effectFusion Material]]s which explicitly states that the summon is a Fusion Summon.

==How to Fusion SummonMechanics==During their [[Main Phase 1]] or [[Main Phase 2|2]], the turn player can A Fusion Summon can only be performed by a Fusion Monster from the Extra Deck by first declaring the action and then [[activateeffect|activatingcard effect]] "Polymerization". Following this, they select the Fusion Monster in their Extra Deck Card effects that they intend to Fusion Summon. They then [[send]] first require the requisite player to "use" appropriate monsters as [[Fusion Material]]s in their [[hand]] or on their side of the [[Field]] to the [[Graveyard]], as listed on the a Fusion Monster itself. After by moving them from some location(s) to another, then after that, Fusion Summon the Fusion Monster is taken from the [[Extra Deck and placed on the field in ]] [[face-up]] to an unoccupied [[Attack PositionMain Monster Zone|AttackMain]] or [[Defense PositionExtra Monster Zone]].

When an effect to Fusion Summon resolves, if the required 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 Summon when "Polymerization" resolves, no monsters are sent to the Graveyard as Fusion Material. Even if all of 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 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=Konami |title=ExampleYu-Gi-Oh! Official Card Game - Perfect Rulebook 2015 |url=https://ygorganization.com/perfectrulebook/ |page=72}}</ref> <gallery position===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 Summoning effects. For example, "[[D/D Swirl Slime]]" ([[Monster Card]]), "center[[Polymerization]]" captionalign=([[Spell Card]]), "center[[Necro Fusion]]">([[Trap Card]]). Polymerization-SP15-EN-C-1E* 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)** "[[Parallel World Fusion]]" (shuffles banished monsters into the Deck as material)** "[[Brilliant Fusion]]" (uses monsters in the Deck as material)DarkMagician** "[[Odd-YGLD-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:** "[[Fusion Material Magistus Invocation]]" (can use MonsterCards treated as [[Equip Card]]s as material)BusterBlader-YGLD-EN-C-1E-C.png |+ A ** "[[Pendulum Fusion Material ]]" (can use [[Pendulum Monster]]s in the [[Pendulum Zone]]s as material)DarkPaladin-YGLD-EN-C-1E.png |= A ** "[[Vision Fusion ]]" (can use MonsterCards treated as [[Continuous Trap]]</gallery>s as material)

==Advanced rulings==* Fusion Summoning effects can perform particular actions on materials beyond simply moving them. Examples:If a ** "[[Monster Card|monster]] is [[Special Summon]]ed from your [[Extra DeckRapid Trigger]] " (Fusion Summons by a [[card effect]], it is not treated as a destroying Fusion Summon, unless stated on the card. For example Special Summoning a monster from your Extra Deck using Materials)** "[[Cyber-SteinDark World Accession]]" is not considered a (Fusion Summons by discarding Fusion Summon.Materials)

Normally, * Fusion Monsters cannot be Special Summoned from Summoning effects can entirely ignore the material requirements of the [[Graveyard]] or [[Banished Zone]] unless they were properly Fusion Monster being Fusion Summoned first before being sent there. You cannot use The sole example of such an effect is "[[Re-FusionThe Eye of Timaeus]]" to [[revive]] a , which Fusion Monster that has been Special Summoned Summons specifically using "Cyber-Stein" or sent to the Graveyard by only 1 "[[Fusion GuardDark Magician (archetype)|Dark Magician]]"monster, even though all of its applicable targets require at least 2 monsters as materials.<ref>[https://www.

==Alternate methods=Interactions with effects===Other * Some cards have effects that allow the player to use monsters from locations other than using the ones specified in the Fusion Summoning effect as materials when Fusion Summoning (e.g. "[[Cybernetic Fusion Support]]", "Polymerization[[Chain 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, cards 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 using the effects with listed Fusion Materials|must be Fusion Summoned with their listed Fusion Materials]], which prevents Fusion Substitute Monsters from substituting any of the following cardsFusion Materials. Be sure 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 follow the instructions on the or [[Treated as alternate name|treated]] as a different card name from being used as a material according to Fusion Summon the monster correctlythat name.

: ''See list [[===Treating a Special Summon as a Fusion Summons]]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.''

==In the animeRush Duel==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-VRush Duel]]'' where a standardized version of this method , the main card for Fusion Summoning is adopted for all "[[Fusion (Rush Duel)|Fusion]]". "Fusion Summons, with " can only use face-up monsters from the portal consisting of blue and orange swirls of energy, referencing the artwork of controller's field as Fusion Materials. "[[Polymerization (Rush Duel)|Polymerization]]", and the Fusion Material Monsters transforming into differently colored forms of energy "[[Power Bond (usually the colors being contrasting ones like blue/red, yellow/violet, etc.Rush Duel)|Power Bond]]" are also available as [[Legend Card]]s, which then swirl together into a spiral before entering the portal. Fusion Summon practitioners usually clasp their hands together at the moment the monsters combineand other Spells, seemingly mirroring Traps and monster effects that the materials become onecan perform Fusion Summons have subsequently been added.

Prior to ==Appearance=====Anime=======''ARCYu-VGi-Oh!'', ''GX'', ''5D's'', and ''ZEXAL''====Visual depictions of Fusion Summons have varied significantly among the first four anime series. Typically, another depiction 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 SummonMonster emerges. One depiction, notably used for "[[Dark Paladin]]" and "[[Dragon Knight Draco-Equiste]]", 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.
