Synchronization

Synchronize is an unofficial term used to refer to the state of mind that Yūya and his Dimensional counterparts occasionally enter.

Effects
This ability causes Yūya and his counterparts to sync with each other, causing both parties to adopt some mannerisms of the other, including speaking the same words and moving in the same manner. The first instance of this happened when Yūto was dueling Yūgo, where they both entered Berserk Mode. In the second instance it repeated itself with Yūya who was able to experience and influence a duel as if he were one with Yūgo. Both Yūya and Yūgo exhibited certain traits of the other user during the phenomenon. Yuzu Hīragi was able to notice this change in behavior on Yūgo's end in the duel. When they regain their senses, they generally have no knowledge of what happened while they were Synchronized.
