Synchronize (ability)

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

Effects
This ability causes Yugo and Yuya to sync with each other, causing both of them to adopt some mannerisms of the other, including speaking and moving in the same manner. Yuya's consciousness is transferred into Yugo and gradually, the users lose the ability to distinguish their identities from each other and begin to act as the same person. When they regain their senses, they generally have no knowledge of what transpired while they were synchronized.

History
The first instance of Synchronization happened between Yuya and Yugo during the Friendship Cup, and was triggered when Yuya picked up his "Odd-Eyes Pendulum Dragon" card after "Clear Wing Synchro Dragon" was Summoned. Both Yuya and Yugo exhibited certain traits of the other user during the phenomenon. Zuzu Boyle was able to notice this change in behavior on Yugo's end in the Duel.

Later, Yugo's Summoning of "Clear Wing Synchro Dragon" in his Duel with Selena once again caused Yuya to sync with him, transferring his awareness into Yugo's body.
