Xyz Materials (pronounced ik-seez; Japanese: エクシーズ
Xyz Materials are essential to Xyz Monsters as in most cases they are used as a cost for a card effect. Removing an Xyz Material for the effect of an Xyz Monster is referred to as "detaching", and the Xyz Material is sent to the Graveyard. If the Xyz Monster is destroyed, banished, or leaves the field, any remaining associated Xyz Materials are also sent to the Graveyard.
Xyz Materials underneath Xyz Monsters do not count as monsters, so detached Xyz Materials will be sent to the Graveyard even if "Dimensional Fissure" is on the field. While monsters are acting as Xyz Materials, they cannot be targeted or apply their effects. Unlike the terms Fusion Material Monster and Synchro Material Monster, the term "Xyz Material Monster" is never used.
Xyz Materials are not treated as being on the field, as seen in the October/November 2011 issue of Shonen Jump and later confirmed by Konami. Therefore, when an Xyz Material is detached, any "leaves the field" effects it may have are not activated. For example, the search effects of "Sangan" and "Goblin Zombie" do not activate upon being detached, and "Reborn Tengu" does not Summon a copy of itself when it is detached. In addition, turning a Monster Card on the field into an Xyz Material through an Xyz Summon does not treat that monster as leaving the field either.
Should a monster acting as Xyz Material have an effect which activates in the Graveyard regardless of whether it was sent there from the field, such as with "Dandylion", "White Stone of Legend", "Tour Bus from the Underworld", "Eclipse Wyvern", or "Needle Sunfish", then the effect can activate upon being detached, as it does not specify that it must be sent from the field.
Certain cards such as "Overlay Owl" allow you to forcibly detach Xyz Materials from monsters. "Overlay Eater" has the effect of taking an opponent's Xyz Monster's Xyz Material and attaching it to an Xyz Monster you control. "Xyz Unit" can count itself as an Xyz Material while equipped to an Xyz Monster. Other cards, such as "Xyz Reborn" and "Overlay Regen", can attach themselves as Xyz Materials to Xyz Monsters even though they are not themselves Monster Cards.
In Yu-Gi-Oh! ZEXAL, as previously noted, Xyz Materials are instead called Overlay Units, and are depicted as orbs of light orbiting the body of the Xyz Monster and colored the same as the Xyz Monster's Attribute. Additionally, during an Xyz Summon, the cards to be used as Xyz Material light up with the Attribute color of the Xyz Monster before being overlaid. When the player detaches Xyz Materials for their respective Xyz Monster's effect, the Xyz Monster is shown to absorb the Xyz Material through several methods, such as through their mouths or any weapon they may be carrying. In some cases, the Xyz Monster will glow the color of the orb it absorbed before releasing its effect. Uniquely, the Xyz Materials of "C" monsters of Barian origin are depicted as magenta crystals that appear in front of or behind the monster. These are named Chaos Overlay Units. In ""Yu-Gi-Oh! ARC-V", Xyz Materials are still absorbed by the Xyz Monster but sometimes they are thrown on the opponent's target monster instead.
