Sage Harpuia

Sage Harpuia, known in the Japanese version as Kenshou Harpuia (「賢将」ハルピュイア, 「Kenshō」 Harupyuia, literally Wise General Harpuia) or simply as Harpuia is a member of the Four Guardians of Neo Arcadia in the Mega Man Zero series. He was created from X' DNA towards the end of the Maverick War with the task of cleaning the skies and atmosphere of toxic gases after the war had ended. Some time later, he became a military general of Neo Arcadia, commanding the Rekku Army (literally Army of the Fierce Sky), Neo Arcadia's military air force. In Mega Man ZX, he makes an appearance as Biometal Model H.

Personality
Originally, Harpuia was a stubborn and loyal follower of X and later his dublicate Copy-X. He was filled with proud in serving such a heroic leader and fulfilled any task given by either of them with absolute obedience and without any hesitation. However, things began to change when he suffered his first defeat in decades at the hands of Zero. His pride fell down to Earth and he slowly began to realize that battles couldn't be won if one didn't have the will for it.

Harpuia matured during the course of the story, becoming more and more like the real X in terms of character and determination, sharing the same opinion that humans and Reploids in fact can live in peaceful coexistance, but will still destroy every Reploid who tries to threaten humanity.

Maverick War era
Sometime during the Maverick War, four Reploids were created from the DNA of Mega Man X. These were Phantom, Fairy Leviathan, Fighting Fefnir and Sage Harpuia. Originally, those four were designed to fulfill certain tasks to rebuild the planet after the end of the war. It was Harpuia's task to clean the atmosphere. To do so, he commanded a giant weather control mechaniloid. However, it is unknown whether or not he completed that task because shortly after the Maverick War had been ended by X and the Mother Elf, a new war broke out, the Elf War.

The Elf War
The role of Harpuia and his siblings during the Elf War is unknown, but it is most likely that they pariciated as combatants in the name of humanity during the war, assisting X in his battle against Dr. Weil and his creation Omega.

Rekku Army
At some point, either before, during or after the end of the Elf War, Harpuia, along with his three siblings, became military generals of Neo Arcadia, responsible for the overall safely of Neo Arcadian habitants, both humans and Reploids. Harpuia, given his unrivaled superiority in the sky, was appointed to become the leader of the Rekku Army, Neo Arcadia's Air Forces. He commanded various air-type forces and Mutos. The Mutos Reploids Aztec Falcon, Herculious Anchortus, along with his brother Kuwagust Anchortus and Panter Flauclaws belonged to his forces.

Mega Man Zero 4
Harpuia made no appearance in Mega Man Zero 4 and wasn't mentioned either. However, prior to the Japanese release of the game, a web blog entry of the developers stated that X, along with the Four Guardians, assisted humans outside Neo Arcadia in escaping Dr. Weil. An artwork featured in Vile's Incident, a information booklet included in Remastered Tracks Rockman Zero Physis, a soundtrack CD of the game with rearranged music, showed Harpuia, along with his siblings and Original-X, witnessing the fall of Ragnarok, all of them wearing ceremonial coats. However, with the release of Rockman Zero: Official Complete Works, the picture was retconned and the remaining three of the Four Guardians were stated to have died in the explosion of Omega at the end of Mega Man Zero 3, deeming the artwork fanservice and not actually canonical.

Armed Phenomenon
Like his three siblings and Copy-X, Harpuia possesses a powerful alternative form called "Armed Phenomenon" which he is able to activate when facing tougher enemies. When activating his Armed Phenomenon, Harpuia's body transforms into a giant green and white plane modelled after a harpy, with giant wings and two clawlike feet. In this form, he attacks with poweful dash attacks, as well as generating chains made of lightning energy and generating tornados with his two thrusters located within his wings. He is also able to fire several missiles from his body.

Other than Copy-X or his siblings, Harpuia was forced to activate his Armed Phenomenon in Mega Man Zero 2 when he was possessed by the Babyelves while trying to fight Elpizo in the Temple of Wind and was manipulated into battling Zero in this form. When he was defeated, he reverted to his normal form again and the Babyelves left his damaged body.

Other Appearances

 * Harpuia has his own mini-game in Mega Man Zero 3 in which he rides Aztec Falcon, a boss in the first game and seen with him on it in the second one.

Trivia

 * Harpuia's gender was a subject of discussion in the English speaking Mega Man community when he made his first appearance in Mega Man Zero. Due to his mythological background of being a harpie and Ogata Megumi's voice acting, he was thought to be a female, which is not true. However, even today, Harpuia's gender is still being confused by players not familiar with the series.
