Xyz Material

Exceed Material Monsters (エクシーズ素材, Ekushīzu sozai, known as Overlay Units in the anime), are the result of monsters being used in an Exceed Summon. When an Exceed Monster is Summoned, the monsters used in the Exceed Summon are stacked underneath the monster instead of being sent to the Graveyard (referred as being "Overlaid" in the anime), and so only one Monster Card Zone is occupied. Exceed Material Monsters are essential to Exceed Monsters as in most cases they are used for a card effect, such as that of "No. 17 Revise Dragon". If the Exceed Monster is destroyed or removed from the field, any associated Exceed Material Monsters are sent to the Graveyard. When an Exceed Material Monster stacked under an Exceed Monster is removed, it is sent to the Graveyard. Removing all of the Exceed Material Monsters associated with an Exceed Monster can have negative consequences, as in the case of "No. 39 Aspiring Emperor Hope". Exceed Material Monsters underneath Exceed Monsters do not count as monsters, or as being on the field.

In Yu-Gi-Oh! ZEXAL, Exceed Material Materials are depicted as orbs of light orbiting around their respective Exceed Monsters.
