Atlas

Atlas is the Biomatch for Model F and a boss character in Mega Man ZX Advent. She is fought in the Oil Fields.

Personality
Atlas has an exceptionally aggressive disposition and values power above everything else. She had previously fought as a soldier in a country that has been ravaged by Mavericks. She has developed the belief that human beings can only evolve during times of war, wherein the strong survive and grow stronger, while the weak perish in their wake; thus she plays the Game of Destiny in order to plunge the world into a never-ending state of war in order to spur on human evolution. It is therefore curious that she would co-operate with her Mega Man opponents such as Thetis, who wishes for the complete extermination of the human race.

Mega Man ZX Advent
She first appears with Thetis in the Artic Ice Floe. After introducing themselves, they Megamerge. However, they don't fight the player. She uses her cannon to shatter the ice the player is standing on, leaving you to fight Chronoforce. You encounter her again at the Oil Fields, attacking the Raiders to feed their souls to Model W. She reveals that she wants to evolve humanity. After her defeat, her form is copied by Model A's A-Trans. She appears briefly with the other Mega Men when you break Aeolus's cipher and in the Ouroborous after the defeat of the eight Pseudoroids. She and the other Mega Men are about to fight Grey/Ashe when Vent/Aile appears and holds them off. During the destruction of Ouroboros, Model Z seperates from Vent/Aile and freezes the other Biometals and their Mega Men. Her fate is unknown, but if the game is beaten in Hard Mode, it is shown she and the other Mega Men are well and alive. (It's also implied that the original immortal Reploid Data was inserted into them, as, right after Master Thomas asked Master Mikhail what he think happened to the original immortal Reploid data, they showed up).

Trivia

 * Despite Model F being derived from Fefnir, Fefnir never had the ability to control his bullets so they would curve in odd trajectories around the room, nor did he have bombs. This could probably be explained by the fact that it was to make Model F more useful gameplay wise, or that MegaMerging powers Biometal up, because Phantom never had a shadow dash or X's Rolling Shield until Megamerged.
 * Like Leviathan of the four guardians, Atlas is the only female of the 4 megamen you face as an enemy in ZX Advent (Aile is fought out of misunderstanding). Ironically, Atlas is of the Fire element, whileas Leviathan is of the Ice element.
