After Nasch's death in his past life, he was reincarnated as a Barian and was chosen as the Barian leader by the denizens of Barian World. Due to this, his emblem came to symbolize the Barian World and its residents. Each of the Seven Barian Emperors possess similar, though unrelated emblems. Those who are brainwashed by a Barian have this emblem appear on their foreheads and no longer require the need of their own Duel Gazers to see the Augmented Reality Duel. One of their eyes just becomes red instead. When Vector possessed Dr. Faker, the emblem appeared on his forehead.
