Guardians

Overview
The Guardians is a volunteer group started by Ciel after the events of Mega Man Zero 4, and acts as a resistance against Serpent's company, Slither Inc. They take deliveries from Giro Express, whose owner is also a part of the Guardians. In the first game, they place an order for the delivery of Biometal Models X and Z. When Aile/Vent gains Biometal Model X, she invites them to join the Guardians.

The Guardian headquarters is a giant air ship which, in the first ZX game, is referred to commonly as Area X.

Ciel


Ciel formed the Guardians before the events of the ZX series, and led them as their first leader up until she disappeared after an investigation in an Outlands area involving the appearing maverick attacks.



Prairie


Prairie leads the Guardians during the events of the first game in the ZX series. She bears a striking resemblance to Alouette from the Zero series, who considered herself Ciel's little sister.



Vent and Aile
Vent/Aile are the hinted as the new leaders of the Guardians in Mega Man ZX Advent, due to the lack of Prairie's presence and their statement that they lost many close friends during fights with Model W.



Girouette


In Aile's storyline, Girouette was always a member of the Guardians and knew about Biometal all along, and simply never told her; in Vent's storyline, Girouette joins them at the same time as Vent, and didn't know what Biometal was until he and Vent met Fleuve.



Fleuve
Fleuve is the scientist of the Guardians, and seems to know the most about Biometal of all its members. He bears a slight resemblance to Perroquiet from the Zero series.



Trivia

 * The Guardians' uniforms bear a striking resemblance to the Resistance from the Zero series.
 * In addition, the fact that Ciel was the original leader, and Prairie and Fleuve having similarities to Alouette and Perroquiet, respectively, may indicate that the Guardians may have evolved from the Resistance.
