Fusion Monster in the game of Yu-Gi-OH. They were one of the first monsters that comes from the extra deck (the 15-card extra deck). In this card game, you would need a card called polymerization (which is a spell card). What you would do next is take two or more monsters that is listed in the text. For example, with the picture that has been listed below. You would take the monster dark magician and red-eyes black dragon and with the polymerization card then you can summon the red-eyes dark dragoon. There are other means of bringing a fusion monster out from the extra deck other than using the spell card polymerization. This would include cards such as effect monster that is listed in its text fusion summon. This can also be used with others monsters such as a link monster that is called pre-da plant Verte Anaconda that monster is a link monster. The description listed below will better example the visual style of summoning a fusion monster. Now recently there is a mechanic in the card game of Yu Gi OH where you would not need the card polymerization. This is referred to as contact Fusion, this is when like it was said earlier that you would not need the card polymerization. What you would do for this mechanic is this. First, you should fine on the fusion card this text "Must first be Special Summoned (from your Extra Deck) by banishing the above cards you control and/or from your GY. (You do not use "Polymerization".)" With this, if the requirements have been met. You can perform your fusion summon in your game.
