When an Xyz Summon is performed, the Xyz Materials then turn into forms of energy whose colors match their Attributes before shooting into the air, sometimes spiraling around each other. A red-colored spiral swirling portal known as an [[Overlay Network]] then appears, and the energy forms enter the portal. The newly Summoned Xyz Monster then emerges from the portal, its Xyz Materials, now colored in accordance with its Attribute, orbiting around it. The emergence from the portal differs between ''[[Yu-Gi-Oh! ZEXAL]]'' and ''[[Yu-Gi-Oh! ARC-V]]''; in ''ZEXAL'', the portal twists shut and explodes with as spheres of light; in ''ARC-V'' a column of blue energy emerges from the portal (although the color of the energy is different for some monsters, such as "[[Odd-Eyes Raging Dragon (anime)|Odd-Eyes Raging Dragon]]" for which red energy emerged)that leave behind fading trails.

Certain monsters, especially "[[File:NumberOverlayNetwork.png|thumb|left|The Overlay Network of the "Number]]" monsters, may have unique or specially designed Overlay Networks of a different color or shapewhich also serves as the stardard one in ''ARC-V''. ]]The idea appearance of a spiral-shaped the portal is derived from Konami's statement that Xyz Monsters entered our universe through a black hole. However, in differs between ''[[Yu-Gi-Oh! ARC-VZEXAL]]'', all Xyz Summons used the galaxy-style spiral portal used largely by "Number" cards from and ''[[Yu-Gi-Oh! ZEXALARC-V]]''; in ''ZEXAL'', the portal is usually a simple red vortex that twists shut and explodes in multi-colored light, but certain monsters have unique or specially designed Overlay Networks of a different color or design. The most obvious example is the "[[Number]]" archetype, which employs a more gradiose visual of yellow particles over a dark purple nebulosity, forming a distinct spiral shape highly resembling a stylized galaxy. This animation is likely a reference to a statement from Konami that says Xyz Monsters entered our universe through a black hole.

In the Interestingly, all Xyz Summons in ''Yu-Gi-Oh! ARC-V'' used this "galaxy-style portal", although compacted in size, as well as replacing the "shutting and exploding" effect with a simpler pillar of blue energy erupting out from the center. Subvariations exist, such as "[[Odd-Eyes Raging Dragon (anime)|Odd-Eyes Raging Dragon]]" producing red energy instead. Of note, an Xyz Summon performed using monsters that have been [[Pendulum Summon]]ed is referred to as a "Pendulum-Xyz Summon", and [[Shay Obsidian]] also refers to an Xyz Summon performed using both an Xyz Monster and a non-Xyz Monster as materials as a "[[Cross Xyz Summon]]".

[[Shay Obsidian]] also refers to an Xyz Summon performed using an Xyz Monster and a non-Xyz Monster as materials as a "[[Cross Xyz Summon]]". In ''[[Yu-Gi-Oh! VRAINS]]'' , the entire sequence is remade: when the Duelist declares an overlaythe overlaying, the Overlay Network appears behind lightning crackles from them rather than in front of them like before. The Xyz Materials fly into the Overlay Network an X-shaped cybernetic array (somewhat similar in design to the Arrowhead portal when performing a [[Link Summon]]ing circuit) materializes behind them. The Xyz Materials fly inside this structure, and once they are set , datastream-like energy that looks like data flows out in front of the Duelist and forms the galaxy-style portal (though now entirely colored light blue), from which the newly formed Xyz Monster emerges. The process is reminiscent of a sci-fi device being used to open a wormhole.
