The portal then explodes, and the newly Summoned Xyz Monster unveils itself. All Most [[Xyz Monster]]s are Xyz Summoned through a red, spiral-shaped portal; however, several Xyz Monstersuse specially designed Overlay Networks with a different color and/or shape. For example, the "[[Number]]" monsters (along with special exceptions a few others) all use a yellow, galaxy-like portal. 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 "[[Number88: Gimmick Puppet of Leo]]" and "[[Number 33: Chronomaly Machu Mech]]" do not have sealed forms and simply emerge complete from the Overlay Network; others such as "[[Number 9: Dyson Sphere]]s", are Xyz too large to ever fit in an Overlay Network and instead materialize in space.)
