Dumon

Dumon, known as Durbe in the Japanese version, is an Emperorof the Barian World in the ''Yu-Gi-Oh! ZEXAL'' anime. After the disappearance of Nash and Marin, Dumon assumed leadership of the five remaining Barian Emperors in an attempt to protect the Barian World from Astral.[4] He was later absorbed by Vector when attempting to protect Marin. He and the other Barian Emperors were revived and revert back into his true human self by the power of the Numeron Code following Yuma's and Astral's final Duel.

Dumon is the only Barian Emperor that never Dueled in his human form, or against Yuma Tsukumo.
