Eurus

Eurus (Japanese: ガーデイアン・エウロス, Gādeian Eurosu, Eurosu) is a member of the Guardians, who helped Dromus and Venetta in their search for the Black Key. He is currently captured by Vilius.

He is voiced by Kyle Hebert in English and by Hideyuki Umezu in Japanese.

History
Eurus was first seen in "The Key to Evil" when he apparently "assisted" the Tenkai Knights in obtaining a new power. He has apparently been assisting Beni and Gen in their efforts to find the Black Key. He claims to have done these things because he believes Boreas has upset the balance in Tenkai Energy, which he wishes to correct. In "A New Knight", he claims to want to help the other Guardians after Vilius went too far. He was captured by Viliius in "Vilius Returns" and is now a part of Vilius's new scheme.
