Fusion Monsters

Fusion monsters are a kind of Monster card in the TCG and HCCG. They are one of two kinds of cards, the other being Synchro Monsters, which are actually placed in the Extra Deck, not the Main Deck. They are color-coded violet. Some Fusion monsters are also Effect Monsters.

Fusion monsters are summoned by fusing 2 or more specific Fusion Material monsters, which are listed on the description of the Fusion monster itself. In order to prepare a Fusion Summon, the Fusion material monsters need to be in the player's possession (although there are exceptions). In most cases, this is done using the card Polymerization; however, there are a few monsters with alternate Fusion methods described on their cards. Fusion monsters also typically have above-average strength or effects.

Fusion monsters are very costly to summon since they require multiple specific monsters to be sent to the Graveyard or banished, and because of this they are hardly ever played outside their respective deck or strategy. However, there are many Fusion monsters currently in the game, including some notable members of archetypes like Cattys, Tanookis, Parrot Dragons, Sea-Kings, and Technicals. In addition, there have been some support cards for Fusion monsters featured in Signal from the Depths, such as Anti-Penetration Unit and Fusion Combi-Relief.
