|Japanese (kanji and furigana)||
Fusion Monsters, colored violet, are cards representing a combination of two or more monsters. Fusion Monsters may only be included in the Extra Deck, and cannot exist in the hand or Main Deck. If a Fusion Monster is returned to its owner's hand or Deck, it is instead sent back to the Extra Deck. However, they may be sent to the Graveyard when destroyed, as well as banished. According to the anime, the Millennium Scale was the item which originally fused monsters. In the Yu-Gi-Oh! they were used on occasion. Early Fusion Monsters were insignificant in terms of ATK and DEF and very few had effects until Yu-Gi-Oh GX, when many fusion cards and many powerful Fusion Monsters were introduced. In Yu-Gi-Oh 5D's, Synchro Monsters appear to have filled this position. However, Fusion Monsters have been used a few times, most notably by Jack in his Duel against Yusei, and Yusei in his Duel against Jean. In Yu-Gi-Oh! ZEXAL Kite used the Fusion Monster Twin Photon Lizard against Shark, while Roku has not yet used Xyz Monsters, using "Blue-Eyes Ultimate Statue Dragon" and "Arcana Knight Joker".
Originally, the only way to properly summon a Fusion Monster was through a Fusion Summon involving the required cards as well as "Polymerization". Monsters fused with "Polymerization" are called Fusion Material Monsters.
In Duels, Fusion Monsters require more specific cards than Synchro Monsters, and aren't as flexible in their strategies. However, Fusion Monsters have the benefit of being able to be summoned without requiring the cards on the field.
If a Fusion Monster is Special Summoned to the field via a card such as "Metamorphosis" and then sent to the Graveyard, it cannot be Special Summoned to the field from the Graveyard with cards such as "Premature Burial", "Call of the Haunted", or "Monster Reborn". In order for a Fusion Monster to be Special Summoned from the Graveyard or Banished Zone to the field, it must first be Fusion Summoned properly through "Polymerization" or a card that specifies "this Special Summon is treated as a Fusion Summon".
There are few Fusion Monsters that have special Summoning Conditions. For example, the "Elemental HERO" Fusion Monsters have a clause stipulating that they may not be Special Summoned unless they are being Fusion Summoned. This also rules them out from being Special Summoned either from the Graveyard or when banished. Others may not allow the use of Fusion Substitute Monsters, and in even rarer cases, both of these conditions may be applied, such as in the case of "Rainbow Neos".
With Duel Terminal - Pulse of the Trishula, Fusion Monsters have started to come back, starting with "Naturia Exterio". In Duelist Revolution and Starstrike Blast, 4 more Fusion Monsters were added: "Ultimate Axon Kicker", "Dragon Knight Draco-Equiste", "Gaia Drake, the Universal Force" and "Supreme Arcanite Magician". These five Fusions are the next evolution of Fusion Monsters. The first evolution was the standard Fusion, requiring two regular Monsters, such as with "Flame Swordsman". The second evolution of Fusions Monsters require at least one other Fusion Monster, such as "Dragon Master Knight". The third and currently most commonly used evolution requires at least 1 Synchro Monster such as "Gaia Drake, the Universal Force".

List of cards to properly Fusion Summon a Fusion Monster
And a few ways to Special Summon a Fusion Monster:
- "Re-Fusion" to Special Summon a Fusion Monster from the Graveyard.
- The "Neos" and "Gladiator Beast" archetypes use "Contact Fusion".
- The "VWXYZ" archetype and "Armityle the Chaos Phantom" use a different type of "Contact Fusion", where the Fusion Material Monsters are banished.
- Chimeratech Fortress Dragon's Special Summon can be seen as a variation of "Contact Fusion", where the Fusion Material Monsters are sent to the Graveyard and you can use your opponent's monsters for the Summon.
- The "Hex-Sealed Fusion" Monster Cards ("The Earth - Hex-Sealed Fusion", "The Dark - Hex-Sealed Fusion", "The Light - Hex-Sealed Fusion")
