Zephyrus

Zephyrus ( Japanese:  ガーデイアユーラス ,  Gādeian Yūrasu, Eng. Translated: Guardian Eurus)  is one of the four  Guardians  of the  portal  to  Quarton  and  Earth  in  Mr. White's shop  and the  Guardians Sanctuary , as shown in " Tenkai Knights: Origins ".

He is voiced by Matthew Mercer in English and by Michiko Neya in Japanese.

History
He was first seen in "Double Crossed", where he felt Eurus coming close to the portal and then started the council by talking about his actions of disturbing the balance of Tenkai Energy.

In "A New Knight", he helped the Knights defeat Vilius. He was captured by Vilius in "Vilius Returns" and is now a part of his new scheme.

Trivia
