Nash

Nasch is one of the Seven Barian Emperors appearing in Yu-Gi-Oh! ZEXAL anime. According to Durbe, Nasch and Merag are also the leaders of this group.

Etymology
His name is derived from Eta Ursae Majoris, also known as Benetnasch.

History
In his past life, Nasch lived his life as a human until he was eventually reincarnated as a Barian.

Both Nasch and Merag are briefly mentioned by Vector, stating that they had vanished from their world one day and that they might be on Earth as well. Vector also told Durbe that on Earth he may be able to pick up on on Nasch's scent. Durbe lamented their current situation, knowing that Nasch would have handled it better than he himself had.

Later during Shark's Duel with Abyss, Durbe and Astral saw Shark's past life, leading Durbe to suspect that Shark and Rio were Nasch and Merag. However, according to Don Thousand, Vector was responsible for Merag's and Nasch's disappearances as the god states that Vector killed them.
