Xyz Evolution

Xyz Evolution, known as Xyz Change in the Japanese version, is a form of Xyz Summoning first seen in episode 18 of the ZEXAL anime and the first variation of the standard Xyz Summon, though when applied to a Chaos Number, it is called a Chaos Xyz Evolution (Chaos Xyz Change in the Japanese anime). What's unique about it is that it can attach Xyz Monsters as its Xyz Material to Xyz Summon which no other Xyz Monsters can perform by themselves. Through this kind of Summon, the original Xyz Monster and its Xyz Materials become the new Xyz Monster's Xyz Material. In anime, the requirement to gain a Chaos Number is for one to "carve a clear path" out of the chaos of confusion into the light.

In the card game, 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 of this card.)''

Abusing the Materials
Because Chaos Xyz 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 Chaos Xyz which adds the normal Xyz as a Material as well.

The different Xyz Evolutions all have different effects. The Chaos Numbers are unable to use their effects, or have to use downgraded effects, unless the Controller's Life Points are equal to or less than 1000. Some Xyz Evolutions like "" actually doesn't use its Materials at all and others like " have drawbacks, such as stunning themselves from using their effects for a turn. Each of these monsters can, instead, benefit the user by supplying Materials.
