The Barian Emblem on Daisuke Katagiri.
Barian Emblem is an emblem that symbolizing the Barian World and its residents in the anime. Those who are brainwashed by them have a Barian Emblem on their foreheads and no longer require the need of their own Yu-Gi-Oh! ZEXAL 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
Brainwashed Duelists Edit
He is the leader in a gang of thieves who Gilag gives Barian power to in order to defeat Yuma Tsukumo and Astral.
He is a Pro-Duelist who is under the control of the heralds of the Barian World.
He is the head of the Student Council at Heartland Middle School, and he was brainwashed by Gilag in order to attack Yuma.
A member of Heartland Academy's Manga club, he was brainwashed by Gilag after Jinguji's defeat. He was also given a supernatural power he used to kidnap and trap Rio Kastle inside the Comic Book World.
She is the leader of the Ikebana Club, and was used by Gilag in an attempt to capture Rio. She was given a supernatural power to put those around her to sleep and incapacitate them.
Tori Meadows & Cathy Katherine
They were used by Gilag in order to defeat Shark and Yuma and recover their " Numbers". Ironically, Gilag was forced to help Yuma defeat the pair to prevent his own demise.
They were brainwashed by Gilag to attack Yuma en-masse to obtain his " Numbers". Alit defeated them all to enable himself and Yuma to have a final 1-on-1 duel.
He was briefly brainwashed by Gilag and used to restrain Yuma while the other brainwashed students attacked him.
Another Pro-Duelist, this time brainwashed by Vector in order to capture Yuma's Numbers. Unlike the duelists Gilag brainwashes– whose personalities change to make them subservient– she acts more like a sleeper agent, retaining her normal personality until she draws Rank-Up-Magic Barian's Force during her duel with Yuma.
Vector gives " Rank-Up-Magic Barian's Force" to Dark Mist as a token of loyalty. His attempt to use the card, however, results in a physical transformation as well as a mental one.
After arriving at the Number ruins, he is brainwashed by Alit so he could be the holder for " Number 54: Lion Heart" and take its risk while also using him to defeat Yuma.
