Fairy Leviathan

Fairy Leviathan, known in the Japanese version as Youshou Leviathan (「妖将」レヴィアタン) 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's 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, she makes an appearance as Biometal Model L.

Design
Like her siblings, her armour is based on that of her biological origin, X, with thematic alterations. Leviathan, being the only female, is the most radically different visually, her armour altered to fit her feminine frame. Her armour is coloured blue, symbolising her alignment with water and ice. Her name is derived from that of the biblical sea monster, Leviathan, and typically refers to any gargantuan sea creature. Her helmet frames her face in such a manner as to resemble hair, with the sides forming 'bangs' and a seashell motif forming the 'fringe'. The back is mounted with a long dorsal fin-like jet, which she uses to propel herself through bodies of water. She wields a harpoon-like weapon, the size of which she can alter, and she uses it to create ice and fire torpedoes.

In her Armed Phenomenon form, Leviathan's armour expands to become a submarine in the shape of a gigantic manta ray, becoming much more fitting of the name 'Leviathan'.

Personality
"Playing 'hero' must be a fun way to pass the time..."

Leviathan seems to like being playful with her opponents before slaying them, as though she enjoys toying with them.

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. However, that would also mean that they fought alongside Zero during this conflict.

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 her 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 Poler Kamrous belonged to her forces.

Mega Man Zero
Leviathan first encounters Zero after he thwarts her attempts to hack into the Resistance (in the "Stop the Hacking" mission). Despite the fact that the battle with her (both in the mission and near the end in the Neo Arcadia Core) is underwater, she is weak to Flame (because she is of the Ice Element).

Mega Man Zero 2
Zero encounters Leviathan in the same Computer Zone that he found Poler Kamrous, albeit in a different part of it. As before, the battle is underwater (Leviathan floods the room upon the start of battle), yet she is still weak to Flame.

Mega Man Zero 3
Leviathan took part in a mission to investigate the wreckage of a crashed spaceship that contained the exiled Reploid, Omega at the beginning of Mega Man Zero 3. She and Fefnir were heavily damaged in the battle and did not reappear again until the final battle with Omega, only being mentioned once in the game, in which Harpuia remarks to X that "Fefnir and Leviathan are still undergoing repairs". In the Remastered Tracks Rockman Zero Telos, the original X and Phantom appear to them and say they must help Zero defeat Omega and Weil.

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, 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 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.

However, the Artwork could have just as easily been of their Cyber Elf forms, since some reploids turn into Cyber-elves when they die (This seems more likely, as Phantom was also present with them in a corporeal form despite his being dead).

Biometal era
Leviathan makes a appearance in the ZX games as Biometal Model L. Vent/Aile combines it with Model X so they can use it against Serpent. Model L further gives evidence its Leviathan as it hold respect for Model X and likes to exchange banter with Model Z, Zero reborn as a Biometal.

In Mega Man ZX Advent, Model L is stolen and used by Thetis. Its suggested Model L is working with him against its will, as Model L was made to stop Model W, and Thetis wanted to awaken it.

Armed Phenomenon
Like her three siblings and Copy-X, Leviathan possesses a powerful alternate form called "Armed Phenomenon" which she is able to activate when facing tougher enemies. When activating her Armed Phenomenon, Leviathan's body transforms into a giant blue submarine modelled after a manta with wide wings and a long tail. In this form, she attacks with powerful dash attacks, razorsharp ice crystals shot from her head gem and torpedos fired from her body. She is also able to materialize Ice Dragons which attack imminate targets or form a prison made of their bodies to entrap their prey.

Trivia

 * The new Robot Master from Mega Man 9, Splash Woman, bears a striking resemblance to Leviathan. Splash woman having a mermaid-like body is close to Leviathan's second form, and the weapon she whield's being a tritent is somewhat close to the Lance Leviathan has. There color scemes are also similar.
