Boreas

Boreas (Japanese: ガーデイアン・ボレアース, Gādeian Boreāsu, Eng. Translated: Guardian Boreas) 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 Steven J. Blum in English and by Shigenori Soya in Japanese.

History
Boreas called out to Guren when he and his father first moved to Benham City. He later allowed Guren to see him in order to guide him and Ceylan to Mr. White's shop, where they were given the Bravenwolf and Tributon cores.

Once all four boys are gathered, Boreas explains the full history of Quarton to them, including the origins and later fall of Vilius.

When Guren and Chooki found the White Dragon Key, Boreas used the dimensional transport devices' special ability to transport it to Quarton. Later Boreas met with his fellow Guardians to discuss both his actions regarding the new Tenkai Knights, and Guardian Eurus's actions.

In "A New Knight", he helped the Knights defeat Vilius.

He was captured by Viliius in "Vilius Returns" and is now a part of Vilius new scheme.

Trivia

 * Boreas is the only Guardian to have his name not switched with another in the Japanese version of the show.
 * Boreas' name and color are based off of the Greek god of the north wind. Boreas (Greek: Βορέας, Boréas), in Greek mythology, was a symbol for the season of winter and coldness, which best represents the color, blue.
