Dark Synchro Monster

Dark Synchro and Dark Tuner monsters are two new monster categories that will be shown in yugioh 5D's in episodes 27 and 28, and will be released in real world in an unknown date. Dark synchro monsters are summoned by sending to the graveyard dark tuner monster and non-dark tuner monster so the non dark tuner level minus the dark tuner level is equal to the dark synchro monster level. Note that dark synchro and dark tuner aren't dark attribute tuner and synchro monsters but completely other monster categories, although they are similar. Currently the only dark synchro monster known is Freezing Fitzgerald.
