A Fusion Summon can only be performed by a card effect. Card effects that Fusion Summon first require the player to "use" appropriate monsters as Fusion Materials 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 face-up to an unoccupied Main or Extra Monster Zone.
Most commonly, cards with effects that can Fusion Summon are Spell Cards (e.g. "Polymerization"). These effects typically involve using monsters from the player's hand or field as Fusion Materials. If not otherwise specified in the card text, monsters used as Fusion Material are sent to the Graveyard.
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.
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), "Polymerization" (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. 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:
- Fusion Summoning effects can perform particular actions on materials beyond simply moving them. Examples:
- "Rapid Trigger" (Fusion Summons by destroying 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" monster, even though all of its applicable targets require at least 2 monsters as materials.
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", "Chain Material").
- Fusion Substitute Monsters 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 Attributes instead.
- Some Fusion Monsters have a condition that they 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 changed to or treated as a different card name from being used as a material according to that name.
Treating a Special Summon as a 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.
Yu-Gi-Oh!, GX, 5D's, and ZEXAL
Visual depictions of Fusion Summons have varied significantly among the first four anime series. 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, 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.
In the Yu-Gi-Oh! anime, under Battle City Rules, which applied during the Battle City tournament, Fusion Monsters cannot attack the same turn they are Summoned. This is exemplified in episode 65, when Strings uses "Quick Attack" on "Humanoid Worm Drake" to bypass that rule in his Duel against Yami Yugi. This rule does not exist in the OCG/TCG and was removed for all subsequent series.
In Yu-Gi-Oh! ARC-V, 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 bright white light. It is 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 Summoned is referred to as a "Pendulum-Fusion".
In Yu-Gi-Oh! VRAINS, 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.
In Yu-Gi-Oh! SEVENS, 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" creates a "Road" from the Duelist's Duel Disk, then it shows the listed materials fuse by overlaying one over another, creating a a large colored beam, the Fusion Monster is generated afterwards.
