Dark Synchro Pendulum Monsters

Dark Synchro Pendulum Monsters are a special category of Pendulum Monster that also count as a Dark Synchro Monster, and can therefore return to the Extra Deck face-up when they would be destroyed, and can then be Pendulum Summoned in certain conditions after a proper Dark Synchro Summon. In very rare cases, "Dark Synchro Pendulum Monsters" can also place themselves into a Pendulum Zone via an effect and serve as a Pendulum Scale.
