Prairie

Prairie (プレリー) is a character in the Mega Man ZX video game. Her name means "meadow" in French. Prairie is the current leader of the Guardians, having the position since the original leader disappeared. They are considered an unofficial part of Slither Inc. The Guardians take in people on a voluntary basis to defend "Frontier" areas from Mavericks and discover what causes these outbreaks. Their headquarters is the giant flying ship known as "Guardian HQ."

Prairie took command of the Guardians after the original leader (who was revealed as Ciel) went missing after an investigation of an "Outlands" area involving the appearing Maverick attacks. At the start of Mega Man ZX, she hired the Giro Express to transport the Biometals "Model X" and "Model Z".

It is revealed in the game that Prairie is over 100 years old, as she was present when she saw Ragnarok breaking apart in the atmosphere or when she sees Zero and Ciel going to fight a swarm of Mavericks, and later during the time of the Models' first discovery. It is also hinted that Prairie may be Alouette from the original Megaman Zero games herself (her stuffed doll, which Alouette always carried, and her reference to the original leader as 'Sis,' which Alouette always used for Ciel).

In Aile's storyline, Prairie is hinted to have fallen in love with Girouette, being said that Giro reminded her of someone she knew before - an obvious reference to Zero, while in Vent's, it has been hinted that she starts to like Vent a bit also. Also, in Aile's storyline, you can see Ciel once you have finished eight missions.

In Mega Man ZX Advent, Vent/Aile bring the Guardian HQ in to invade Ouroburos, calling it their airship. It isn't explained what happened to Prairie, but Vent/Aile mentions losing a lot of friends fighting Model W, suggesting Prairie may have been killed, leaving Guardian HQ to them (but this is extremely hard to prove, as the two had been only syaing it in general, not specifically).

Prairie is voiced by Ryō Hirohashi, who also voiced Alouette.

Trivia

 * Prairie is one of the few main charecters that actually disappears canonically with no apparent explanation (she leaves no trace of herself in ZX). Other charecters are Zero/Model Z (who has done it time and time again), Ciel (who has conflicting explantions in ZX), and Bass.EXE (in the anime, he jacks out, never to return).
