Chaos Xyz Evolution, known as Chaos Xyz Change (カオス・エクシーズ・チェンジ Kaosu Ekushīzu Chenji) in the Japanese version, is a form of Xyz Summoning in Yu-Gi-Oh! ZEXAL anime. It was first seen in Episode 18 by Yuma Tsukumo. Xyz Monsters are used as Xyz Material to perform the Summon which no other Xyz Monsters can do by themselves.
Through this kind of Summon, the original Xyz Monster and its Xyz Materials become the new Xyz Monster's Xyz Material. In the anime, the requirement to gain a Number C is for one to "carve a clear path" out of the chaos of confusion into the light. Additionally, in the Barian Invasion arc, Chaos Xyz Evolution can be also achieved by using a Rank-Up-Magic card, such as "Rank-Up-Magic Barian's Force".
In the OCG/TCG, this is treated as a regular Xyz Summon (similar to Accel Synchro Summon) The common effect in monsters that use this summon method states You can also Xyz Summon this card by using 1 [specified Xyz Monster] you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials on this card.)

Abusing the MaterialsEdit
Because CXyz Summoning is just a single step above regular Xyz Summoning, these cards make it easy to abuse cards that require amounts of Xyz Materials on your, or your opponent's, side of the field. This is because the original Xyz Monster can be summoned, and possibly use its effect, just to be made into a CXyz which adds the normal Xyz as a Material as well.
Out of the current 4 CXyz Monsters, the two Chaos Numbers are unable to use their effects unless the Controller's Life Points are equal to or less than 1000. These effects can make the monsters seem like effect-less monsters for most of the time. On the other hand, "Gaia Dragon, the Thunder Charger" doesn't use its Materials at all and "Constellar Ptolemy M7" stuns itself from using its effect for a turn. Each of these monsters can, instead, benefit the user by supplying Materials.
- While using effects like "Blue-Blooded Oni", "Xyz Energy" or "Utopian Aura", Materials on your field are required to be detached. Consider using a CXyz to increase the amount of Materials that you control by one. (See Detaches Xyz Materials for cost)
- While using effects like "Neo Galaxy-Eyes Photon Dragon", "Kurivolt", or "Red-Headed Oni", Materials on field are detached. Sometimes it is required for the Material to be on the opponent's side of the field. Consider using a CXyz with "Creature Swap" to ensure your opponent has Materials for you to use. (See Detaches Xyz Materials for effect)
Example Chaos Xyz EvolutionEdit
- "Number 92: Heart-eartH Dragon" can be Summoned in a way similar to Chaos Xyz Evolution. When "Number 53: Heart-eartH" with no Overlay Units is attacked (destroyed by a card effect in the OCG/TCG), "Number 92" can be Xyz Summoned by using "Number 53" as Overlay Unit.
