Changes

According to [[Konami]], [[Xyz Monster]]s have traveled to [[Earth (planet)|Yuma's dimension]] from the other side of a black hole.<ref name="SD11">{{citeweb|url=http://www.yugioh-card.com/en/products/starter2011.html|title=Starter Deck: Dawn of the Xyz|publisher=[[Konami]]}}</ref> When a [[Duelist]] performs an [[Xyz Summon]], the [[Xyz Material]] monsters transform into streaks of energy, and an Overlay Network appears in the form of a portal that the energy streaks enter. The portal then explodes, and the newly Summoned Xyz Monster unveils itself.<ref name="ep1">{{episode|Yu-Gi-Oh! ZEXAL|1|ref}}</ref> In ''[[Yu-Gi-Oh! ARC-V]]'', instead of exploding, a column of blue lightning emerges from the center of the portal. Most [[Xyz Monster]]s are Xyz Summoned through a red, spiral-shaped portal, though "[[Neo Galaxy-Eyes Photon Dragon (anime)|Neo Galaxy-Eyes Photon Dragon]]" utilizes a pink one<ref name="ep43" /> and "[[Shark Caesar (anime)|Shark Caesar]]" a blue.<ref name="ep91">{{episode|Yu-Gi-Oh! ZEXAL|91|ref}}</ref> After being Summoned, the Xyz Materials then become [[Xyz Material|Overlay Unit]]s that orbit the Xyz Monster as orbs of light.<ref name="ep1" />

The "[[Number]]" monsters all use a yellow, galaxy-like portal.<ref name="ep2">{{episode|Yu-Gi-Oh! ZEXAL|2|ref}}</ref><ref name="ep13">{{episode|Yu-Gi-Oh! ZEXAL|13|ref}}</ref> In addition, the sealed form of the Summoned "Number" appears out of the portal first, before transforming itself into its true form (some "Number" monsters such as "[[Number 88: Gimmick Puppet of Leo (anime)|Number 88: Gimmick Puppet of Leo]]"<ref name="ep58">{{episode|Yu-Gi-Oh! ZEXAL|58|ref}}</ref> and "[[Number 33: Chronomaly Machu Mech (anime)|Number 33: Chronomaly Machu Mech]]"<ref name="ep48">{{episode|Yu-Gi-Oh! ZEXAL|48|ref}}</ref> do not have sealed forms and simply emerge complete from the Overlay Network; others such as "[[Number 9: Dyson Sphere (anime)|Number 9: Dyson Sphere]]" are too large to ever fit in an Overlay Network and instead materialize in space<ref name="ep55">{{episode|Yu-Gi-Oh! ZEXAL|55|ref}}</ref>).

"[[Galaxy Stealth Dragon]]"<ref name="ep138">{{episode|Yu-Gi-Oh! ZEXAL|138|ref}}</ref> and all Xyz Monsters featured in ''[[Yu-Gi-Oh! ARC-V]]'' thus far use the "Number" Overlay Network.<ref name="arc7">{{episode|Yu-Gi-Oh! ARC-V|7|ref}}</ref><ref name="arc9">{{episode|Yu-Gi-Oh!
