Dark Tuner monster

Dark Tuner Monsters are a new monster Type that will be shown in Yu-Gi-Oh! 5D's in Episodes 27 and 28. Dark Synchro Monsters are Synchro Summoned by sending to the Graveyard 1 Dark Tuner Monster and 1 non-Dark Tuner Monster. The non-Dark Tuner Monster's Level minus the Dark Tuner Monster's Level must be equal to the Dark Synchro Monster's Level.

Note that Dark Tuner Monsters are not just DARK Attribute Tuner Monsters, but are a completely different monster Type, although they are admittedly similar to Tuner Monsters. There are no known Dark Tuner Monsters at present.
