Omega

Personality: At first, Omega is depicted as Dr. Weil's mindless servant. He is totally obedient to Weil, reverently addressing him as Lord Weil, and exhibits no desires of his own. He rarely speaks in anything but growls and roars, as if a beast. Weil claims he had developed a grudge against Zero and X for defeating him in the first place. Before fighting Zero in Weil's lab, he laughs and calls Zero by name. Once his true form is revealed, Omega lets loose and shows his true colors as a megalomaniacal monster with a god complex. He doubtlessly believes in Weil's insane purpose for him, and when he speaks his first full sentence, he declares himself a Messiah and laughs maniacally. He values the Dark Elf for her power, showing concern when she is reverting back to the Mother Elf. In Megaman X DiVE, Omega's personality is expanded on. Not only does he see himself as a Messiah, but he strangely believes himself to be the real Zero. Despite being merely a new personality inhabiting Zero's original body, he is unable to comprehend how other characters speak of Zero as a separate person.

Appearance: It looks exactly the same as Zero's replacement body in the Megaman Zero series, but with a slightly darker red color, pale hair, and a purple saber. Interestingly, Omega's ponytail does not emerge from his helmet until he summons it before his boss battle. His giant armor: Omega is a giant Reploid with knight-like armor and a long coat. His armor is white and black with red highlights, and his arms are sharp claws detached from his shoulders, which can float freely around his body. His helmet features a black visor that covers his entire face, with a scowling mouth carved below. He has long pink hair rising from the top of the helmet that reaches his feet. He wears a gigantic beam saber on his back that is normally coated in metal. Upon absorbing the Dark Elf, his color scheme changes to gold and black with blue highlights.

Abilities:

Omega's first form is his knight-like external frame, his most recognizable form. He can fire lasers from his torso, and his claws can detach from his body and fire ring projectiles. He is incredibly durable, as the combined might of Fefnir and Leviathan could barely harm him, and Zero was only able to briefly stun him. After absorbing the Dark Elf, Omega received a power boost along with the potential to control all Reploids on the planet at once. He is stronger and faster, and finally chooses to wield the saber he wears on his back.

Hoop Shot: Omega's arms will detach from his body and strafe the room, firing large energy shots resembling lines of rings.

Omega Laser: Omega will spawn three lasers in front of his torso.

Piercing Sword: Omega will draw his saber and hover it over the battlefield, trying to line it up with the player. Periodically, he will slam his saber into the ground - the third and final strike will send debris everywhere.

Omega takes this form using the full power of the Dark Elf. With three heads (Dark Elf's, X's, and Zero's), a sword so massive that the entire blade can't be seen, and a colossal cannon, Omega is a far more formidable opponent. The monster's only weak point is the central face, a relatively small target. Despite these new abilities, this form still pales in comparison to the final form.

Spark Chaser: Omega will summon a laser that follows the player's horizontal path and only turns 90 degrees.

Triple Laser: Omega will fire lasers from the eyes on each of his three heads (the X head fires farthest, the Dark Elf head fires middle-length, and the Zero head fires shortest).

Exceed Buster: Omega will fire three huge energy shots in a row.

Exceed Buster Neo: Omega will fire a laser beam.

Binding Ball: Omega will summon a red sphere, following and trapping the player.

Resting inside the white head of Omega's previous form is Zero's original body, upgraded by Weil to draw out its full power. With a full three health bars, he is just as, if not more dangerous, than his other forms. Omega is an aggressive opponent who often rushes Zero to attack. He wields a Buster Shot identical to Zero's and a purple version of the Z-Saber. He uses some of Zero's attacks from the Megaman X series. In the Elf Wars drama track, Zero mentioned gaining an epiphany that his powers were meant for defending his friends rather than destruction after fighting "the other [Zero]," implying that Omega at some point in the war fought Zero in the latter's original body before being outfitted with the armor.

Triple Slash: The regular attack, a 3-hit O-Saber combo.

Charge Saber: Omega slams the ground with the O-Saber, causing rubble to fall from above.

Arc Blade: Omega spins in the air with the O-Saber, sending crescent waves in seven directions.

Double Charge Wave: Omega fires two charged shots with his buster, followed by a crescent wave with the O-Saber.

Ryuenjin: Omega does a rising slash with the O-Saber.

Messenkou: Omega pounds the ground, unleashing a spread shot in five directions.

Rekkoha: Omega pounds the ground, raining vertical beam pillars down to surround him, rendering him briefly invulnerable.

Ranbu: Omega lunges at the opponent and executes a deadly 7-hit combo with his saber.

Omega, also known as the "God of Destruction", the "Devil Reploid", or the "Ultimate Reploid", is a central antagonist and the final boss of Megaman Zero 3. He is a Reploid created by Dr. Weil as the "perfect ruler" for his Project Elpizo, meant to dominate all Reploids with the power of the Dark Elf.
