Fairy Leviathan

Fairy Leviathan, known in the Japanese version as Youshou Leviathan (「妖将」レヴィアタン, 「Yōshō」Reviatan, literally Siren General Leviathan) or simply as Leviathan is a member of the Four Guardians of Neo Arcadia in the Mega Man Zero series. She was created from X' DNA towards the end of the Maverick War with the task of cleaning the seas and oceans after the war had ended. Some time later, she became a military general of Neo Arcadia, commanding the Meikai Army (literally Army of the Dark Oceans), Neo Arcadia's military navy force. In Mega Man ZX, he makes an appearance as Biometal Model L.

Maverick War era
Sometime during the Maverick War, four Reploids were created from the DNA of Mega Man X. These were Phantom, Sage Harpuia, Fighting Fefnir and Fairy Leviathan. Originally, those four were designed to fulfill certain tasks to rebuild the planet after the end of the war. It was Leviathan's task to clean the seas and oceans from pollution using her elemental powers and her water-based mechaniloid forces. However, it is unknown whether or not she 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 Leviathan and her 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.

Meikai Army


At some point, either before, during or after the end of the Elf War, Leviathan, along with her three siblings, became military generals of Neo Arcadia, responsible for the overall safely of Neo Arcadian habitants, both humans and Reploids. Leviathan, given his unrivaled superiority in the water, was appointed to become the leader of the Meikai Army, Neo Arcadia's Navy Forces. She commanded various water-type forces and Mutos. The Mutos Reploids Blizzack Staggroff and Polar Kamrous belonged to her forces.

Mega Man Zero 4
Leviathan made no appearance in Mega Man Zero 4 and wasn't mentioned either. However, prior to the Japanese release of the game, several magazine articles 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 Leviathan, along with her 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.
