Barian Emblem

A Barian Emblem is an emblem that symbolizing the Barian World and its residents in the Yu-Gi-Oh! ZEXAL anime. Those who are brainwashed by them have a Barian Emblem on their foreheads and no longer require the need of their own Duel Gazers to see the augmented reality. One of their eyes just becomes red instead. When Vector possessed Dr. Faker, the Barian Emblem appeared on his forehead.

Also, all those who are brainwashed by the Barians have a tendency to say "Barian sekai no tame ni", meaning "for (the sake of) the Barian World".
