Some cards monsters can replace specifically named Synchro Material Monsters Materials by [[Changes own name|treating changing their name]] as to that of a specifically named Synchro Material Monster.

For example, "[[Pain Painter]]'s" has its name is treated as "[[Plaguespreader Zombie]]" while it is [[face-up]] on the field. It can be used as the [[Tuner monster]] in the Synchro Summon of monsters such as "[[Archfiend Zombie Skull]]" that require specific Tuner monsters.

If a Tuner monster gains the name of a required non-Tuner monster for a Synchro Summon, it may be used as that monster, in which case the Synchro Summon will use multiple Tuners. The same is not true of the reverse - if If a non-Tuner monster such gains the name of a required Tuner monster for a Synchro Summon, it may be used as that monster, but the Synchro Summon cannot be performed unless at least one of the Synchro Materials is a Tuner monster. For example, "[[Neo-Spacian Dark PantherScanner]]" gains the has its name of a specifically required Tuner such treated as "[[Junk SynchronMajestic Dragon]]", while it is [[face-up]] on the field. Since a Synchro Summon cannot be used performed without using a Tuner monster as a Synchro Material , it can only be used as "Majestic Dragon" for a the Synchro Monster that lists Summon of "[[Majestic Star Dragon]]" if "Junk Synchron[[Stardust Dragon]]" is treated as its a Tuner monster (unless it also becomes a Tuner by an effect).
