While attached to an Xyz Monster (underneath the Xyz Monster Card), Xyz Materials are not treated as being on the requisite monsters needed to [[fieldXyz Summon]]the Xyz Monster.

* There are [[Machine]] monsters with every possible original Rank (from 1 to 12).

There "[[Superdreadnought Rail Cannon Juggernaut Liebe]]", "[[CXyz Skypalace Babylon]]" and "[[Number 81: Superdreadnought Rail Cannon Super Dora]]" are Machine-Type tied with the highest DEF of all Xyz Monsters of all Ranks from 3 to 12, with 4000 DEF each. * "[[Number F0: Utopic Future]]" and , "[[Number F0: Utopic Future Slash]]", "[[Number S0: Utopic ZEXAL]]", and "[[Number F0: Utopic Draco Future]]" are currently the only Xyz Monsters that do not have a printed Rank (although they are always treated as Rank 1) 

** This is most evident when comparing the two visually: both Dark Synchro and Xyz Monsters are black cards with a left-aligned row of modified star pips to represent an alternate property to standard Levels: [[Negative Level]]s or and Ranks, respectively. Both have also been considered "opposite" to standard Synchro Monsters. * Both [[Iggy Arlo]] and the [[Stomptroopers]] in the ''[[Yu-Gi-Oh! ARC-V]]'' anime mistakenly believed Xyz Monsters to be Level 0, because they do not have any Levels. ==Notes==<references group="Notes" /> ==References==<references />
