Xyz Materials (pronounced ik-seez; written as
Xyz Materials are essential to Xyz Monsters as in most cases they are used for a card effect, such as that of "Number 17: Leviathan Dragon". Removing an Xyz Material for the effect of an Xyz Monster is referred to as "detaching". If the Xyz Monster is destroyed, banished, or leaves the field, any associated Xyz Materials are sent to the Graveyard. When an Xyz Material stacked under an Xyz Monster is removed or detached, it is 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 Xyz Materials, they cannot be targeted or activate/apply their effects.
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. When an Xyz Material is detached, any "leave the field" effects it may have are not activated, since they are not treated as being on the field. 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. However, the effect of "Needle Sunfish" will activate upon being detached since its effect only specifies it needs to be sent to the Graveyard to activate, and not necessarily from the field.
However, should an 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.
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.
In Yu-Gi-Oh! ZEXAL, Xyz Materials are depicted as orbs of light colored the same as the Xyz Monster's Attribute, which orbit around their respective Xyz Monsters. Also, during an Xyz Summon, the Xyz Materials' corresponding Attributes light up their bodies. When the player detaches Xyz Materials for their respective Xyz Monster's effect, the Xyz Monster absorbs Xyz Material through several methods, such as, by their mouths, arsenals, etc. In some cases, the Xyz Monster will glow the color of the orb it absorbed before releasing its effect. This is also seen in Yu-Gi-Oh! 5D's Tag Force 6 when the player Xyz Summons a monster. The Xyz Materials of "CXyz" and "Number C" monsters summoned by "Rank-Up Magic" cards of Barian origin are depicted as magenta crystals that appear in front of or behind the monster.
