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.

The Seven Barian Emperors also wear the Barian Emblem in some way in their true forms. The Emblem was originally Nasch's, as he wore it as a pendant in his past life.

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". In the English dub, this chant is not said.

Don Thousand's Emblem
Don Thousand also has his own variation of the Barian Emblem. It has thus far been seen when he has used his powers in other ways such as healing Alito and Girag; resulting in them having a malicious disposition. A crest like image of this version of the Barian Emblem has also been seen being used by members of the Fearsome Four of the Dark Dueling World who use it to halve the opponent's Life Points and add it to their own at the very beginning of the Duel, effectively cheating. This emblem appears on a wall behind Vector while he dueled Reginald Kastle (in their past lives). It also appears on his chest, similar to how the regular Barian Emblem appears on Nasch's chest in Barian form.
