Synchronization

Synchronize is the term used to refer to the state of mind that Yūya and Yūgo entered during the Friendship Cup.

Effects
This ability causes Yūgo and Yūya to sync with each other, causing both of them to adopt some mannerisms of the other, including speaking and moving in the same manner. Yūya's consciousness is transferred into Yūgo and gradually, the users lose the ability to distinguish their identities from each other and begin to act as the same person. This ability is usually triggered when "Clear Wing Synchro Dragon" is summoned.

When they regain their senses, the people involved generally do not know that they have synchronized. However, they retain their memories of the Duel, as Yūya remembers what happened in the Duel between Yūgo and Serena.

History
The first instance of Synchronization happened between Yūya and Yūgo during the Friendship Cup, and was triggered when Yūya picked up his "Odd-Eyes Pendulum Dragon" card after "Clear Wing Synchro Dragon" was Summoned. 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.

Later, Yūgo's Summoning of "Clear Wing Synchro Dragon" in his Duel with Serena once again caused Yūya to sync with him, transferring his awareness into Yūgo's body. The sync is broken with the conclusion of the Duel, with Yūya remembering the Duel and as a result becoming aware of the ability.
