Omega

"Ware wa meshia nari! ("I am the Messiah!")"

- Omega

Omega (オメガ), dubbed "the Devil Reploid", "the Ultimate Reploid" and "perfect ruler" by Project Elpis, is a massive Reploid created during the four years of the Elf Wars. He is Dr. Weil's greatest creation and was made to be the perfect ruler, namely by storing and utilizing the Dark Elf in order to mass-control Reploids remotely, thus preventing them from becoming Mavericks. He plays the major role of being the final boss and the main villain in the story of Mega Man Zero 3 and is a secret boss in Mega Man ZX.

Appearance
In his default form, Omega is a large Reploid with a distinct knight-like theme with a long coat. His color scheme predominantly features white with black in the center of the torso and the face of the head. He has long pink hair rising from the top of the helmet that reaches his feet. He has detachable arms, which feature gigantic hands with black spiked wrists and razor sharp claws.

Personality
Omega is first depicted as a mute, but loyal servant of Dr. Weil. However as the story progresses, he is revealed as an insane Reploid with a god complex. He is the bloodthirsty tool of Dr. Weil's ambitions and is absolutely obedient to his commands, very similar to what Zero was intended to be for Dr. Wily. After returning to Earth after spending a century of exile in space, he developed a grudge against Zero, because he was defeated by Zero despite the latter no longer being in possession of his original body. Also, Omega's ability to speak was reduced to minimum in his exterior armor; in fact, the only words he ever says in this form are a long, drawn out "Zero" and "Lord Weil". Other than that, he doubtlessly believes in Weil's insane purpose for him, being his messiah of the new world order and "God of Destruction".

In the manga, Omega is very different. He is depicted as an average Reploid hunting the Dark Elf, and dislikes Zero, though he doesn't appear to hate him, since he cooperates with him in one chapter of the manga to defeat zombie Reploids. Ironically enough, this version of Omega is also deathly afraid of zombies. Also, other than being a rival of Zero, he has absolutely no ties to Zero whatsoever, unlike in Mega Man Zero 3, where he inhabits Zero's old body. The concept of Omega having a similar body to Zero was instead given to Roze, who was an actual duplicate rather than the original body.

The Elf Wars
After the Maverick Wars had been ended by the powers of the Mother Elf by reverting the viral infection of Reploids caused by the Sigma Virus, Dr. Weil, a weapon researcher and DNA revival specialist who had worked at the same laboratory as the unknown female ancestor of Ciel (who had researched Zero's body) in order to find a way to end the war, felt unsatisfied with the result of the solution. Thinking that it wasn't enough to simply cure the Reploids from the virus while they posed still a threat to society due to their free will, he decided to create his own, radical solution, while making himself to the ruler of the world in the process. Project Elpis was the end result: to create a Reploid to become the perfect ruler, by using the power of the Mother Elf to control all the reploids in the world, thus preventing them becoming Mavericks in the first place.

However, since the world was at peace at the moment thanks to the Mother Elf, he needed to give the government a reason to sanction Project Elpis. He secretly stole the Mother Elf and reprogrammed her into the Dark Elf, whose purpose was to create Maverick outbreaks by brainwashing Reploids. Baby Elves, small copies of the Dark Elf, were mass-produced to cause violent Maverick outbreaks worldwide.

As new Mavericks arose and caused terror and destruction in scales never seen before, the government heeded Dr. Weil's pleas and sanctioned Project Elpis to bring this new and devastating conflict to an end. For the project he was given Zero's body, which possessed the necessary virus countermeasures for to create the perfect ruler, Omega, the messiah of Dr. Weil.

For Omega to control all reploids worldwide with the Mother Elf, a massive armor was constructed around Omega for the Mother Elf to fuse with it. In addition the armor also boosted Zero's body to its absolute limits and granted it the ability to regenerate any damage (Due the limitations of the GBA, it was unable to display Omega's mobility and agility). Along with the armor, Omega received new weapons, suitable for his new size and weight. Unknown to everyone Omega received a new personality, which was absolutely loyal to Dr. Weil's orders. With Omega completed by fusing it with the Dark Elf, the baby elfs would be redundant as they were no longer needed.

Because Zero's body was used for Project Elpis, Ciel's ancestor created for him a new body, so he could fight alongside X and Omega against the new threat. At some point of the conflicts, which were now known as the Elf Wars, Zero reclaimed the Dark Elf from the mavericks and used her to bring the maverick uprisings to a end.

It was then, where Weil revealed his true colours and ordered Omega and a group of Mechaniloids, similar to Neo Arcadia's later Golems, to attack his former allies. However, because Zero reclaimed the Dark Elf in time, Omega was unable to fuse with the Dark Elf. He was defeated after a hard battle by X and Zero using Final Strike.

It is generally unknown for what reason Omega was not destroyed after the end of the war while his creator was punished by the war's survivors, but according to the pamphlet "Vile's incident: Eden's Dome: Its Sin and Rebirth", the reason that Omega was not destroyed is because the Eight Gentle Judges had the same creator as Omega. In any case, Omega was imprisoned within a spaceship and ignited into space, destined to spend the rest of eternity in exile around the earth. However, things would take a different path...

Mega Man Zero 3
Two months after the Dark Elf had been released from her seal in Neo Arcadia by Elpizo, strange energy readings similar to that of the Dark Elf were detected by the Resistance in a frozen tundra. A reconnaissance unit, consisting of Zero, Ciel and a few Resistance soldiers was dispatched to analyze the anomaly. Upon arriving at the location, they found a Derelict Spacecraft. The closer they got to the ship, the stronger the readings became and Neo Arcadian troops had already cordoned off the area. When Zero arrived at the ship's entrance, he was intercepted by Harpuia, who merely ordered him to retreat at once as there were things of bigger importance now than dealing with him before disappearing inside the ship. A strange, yet familiar growl reached Zero's ears from the inside, seemingly calling for him. Zero fought his way through the hostile forces and entered the core of the ship, where fighting was already in progress. At the core, he saw Fefnir and Leviathan battling an enormous Reploid, Omega, but were unable to do so much as damage him. Weakened and damaged, the two Guardians teleported away, leaving Zero and Omega, whom Zero recognized as the one that called him, all by themselves.

The two battled for awhile, with Zero seemingly immobilizing the giant Reploid, but unable to severally damage it due to its ability to regenerate himself. Even after Harpuia joined the battle as well, he managed to hold his ground. At that moment, Dr. Weil showed up at the scene, halting Omega from continuing battle, as Harpuia was now his comrade as a Neo Arcadian. Upon introducing himself, Copy X appeared as well, who had been revived by Weil. Even though Harpuia warned him about all the havoc that Omega caused in the past, he, as well as Weil, were given the permission to enter Neo Arcadia in order to serve Copy X and to regain control over the Dark Elf. All of them (save for Zero) then left to Neo Arcadia. It was later found out that since Omega had returned from outer space, strange green portals had appeared in different locations which seemingly made it possible to travel between the real world and its Cyberspace shadow world.

Back at Neo Arcadia, Harpuia desperately tries to talk Copy X out of trusting Weil, though Copy X claimed his banishment was not a legal one and that, even though his actions caused the most devastating war in history, his banishment was not the verdict of a fair trial. When the Dark Elf was located in Area Z-3079, a residential district with the utmost distance from the Neo Arcadian centre, Copy X stripped the remaining three Guardians of their powers and duties and handed all their military command to Weil in order to catch the Dark Elf. Omega was transported to the missile base near the Aegis Volcano and loaded into a missile which was then fired into the direction of Neo Arcadia to catch the fugitive Cyber Elf. The Resistance, which intercepted transmissions about the start of the missile, sent Zero into the area to halt the take off of the missile. Though he didn't make it in time to stop the take off, Zero boarded the missile to stop Omega, who was at that time immobilized within the missile.

However, he was intercepted by Crea and Prea, two Baby Elves which managed hold Zero off Omega long enough for the missile to reach its destination. The missile crashed into the district, killing many innocent people and totally devastating the area. When Zero regained consciousness, the Dark Elf was in front of them, as well as Omega. The giant Reploid had caught her and absorbed her into his body, causing his white and red armor color scheme to turn gold and blue and boosting his abilities to new heights, thus the perfect ruler was finally created. Harpuia, who hadn't been able to watch anymore, turned against Copy X and tried to fight Omega; however he was no match for him. It was only due to the lucky timing of the Resistance's Operators that Zero and Harpuia managed to survive their encounter with the Devil Reploid.

After Zero managed to stop multiple Neo Arcadian attacks aimed at the Resistance base, he went to stop the problem of the cause, Copy X. The two of them fought with Zero emerging victorious. Copy X called for Weil's and Omega's assistance, however both of them had already disappeared to another location after stealing everything they needed from Neo Arcadia's supplies. When an enraged Copy X tried to transform into his seraph form to destroy Zero once and for all, a self-destruct program within him was triggered, installed into his body by Weil himself, who shortly after claimed leadership of Neo Arcadia by the use of Ordinance #8, as well as encouraging the citizens of Neo Arcadia to support his cause to terminate the extremists.

Zero was then sent to find out more information about both Omega and his creator. Eventually, he located a sunken data library with information about both of them, as well as their actions during the Elf War. Soon after this, Weil had finished the final modifications on Omega to grant him the power to control every Reploid on the planet. While X defended the inhabitants of the Resistance Base with his powers, Zero (who was unaffected by the Dark Elf's/Omega's powers, because his copy body possessed the same imperfect virus counter measures of his old body) rushed for Weil's lab, located near the place where he had once been found by Ciel.

He managed to defeat Weil's servants, the Eight Gentle Judges as well as Omega in his empowered form. Enraged by his defeat, the giant Reploid released the powers of the Dark Elf within him, transforming him into a giant mecha, which was a larger and mightier form of himself. It resembled a strange fusion of himself, X and Zero, as well as being armed with a giant saber and a chargeable buster cannon. However, Zero again defeated him.

Omega's remains and Zero fell down through the floor of Weil's laboratory, only to find themselves right at the place where Zero was found by Ciel. When they did, Weil revealed Omega's secret to him: That he [Zero] was in fact a mere fake thought to be Zero, while the real one was none other than Omega. From the remains of Omega's battle body, Omega's true persona emerged, a Reploid looking completely like Zero, however with Zero's original color scheme and using multiple attack patterns and moves Zero had previously used in the Maverick War and now forgotten (for the most part). Yet, after a fierce battle, he barely defeated him.

Yet, the battle wasn't completely over as Omega used the Dark Elf within him to heal his wounds. The remaining three of the Four Guardians, along with X, appeared to assist Zero in defeating his original body. When they did, the Dark Elf's curse started to fade. Zero regained his strength to deliver the final blow, though Omega used his original body, destroying Omega for good, resulting in a giant explosion that only Zero himself survived due to the protection of the now cured Mother Elf. The destruction of Omega also caused the dimensional portals to disappear. In the end, Zero was still Zero, whether spending his life in a copy of his original body or not, his heart was still the right one.

Mega Man ZX
Omega appears as an optional boss character in Area N of the game. Due to the massive explosion after his final battle with Zero, a rift between reality and Cyberspace was caused, similar to what happened when Omega returned to Earth after his exile. The Omega appearing in Area N is not a rebuilt version of the Reploid but actually a corrupted memory file that remained of Omega when he was destroyed. This is believed to be the case because of the environment around him constantly changing between the normal background of Area N and that of the final battle of Zero and Omega.

Omega Zero operates identically in his Zero 3 version with some lethal differences. Attacks don't stun him as frequently, and he is significantly faster and more aggressive. Here, he uses his Shungokusatsu combo much more often. In addition, his Rekkouha now restores 8 units of his health. His delay time frames to perform another move has been reduced to zero frames, causing Omega to be constantly attacking the player, making the battle much more hectic than in Mega Man Zero 3. Unlike the other bosses found at Area N, Omega is the only one that will not respawn the minute the player enters the room after defeating him. For one to fight him again, the player has to leave the area first and then return for a rematch.

After he is destroyed in Normal or Hard difficulty, he will leave an item called "Mysterious Stone". After clearing the game once, the stone can be taken to Fleuve, who'll analyze the stone and transform it into Biometal O which lets Vent/Aile become Omega, including all powers and attacks he possessed.

It is unknown if Omega's Biometal form in Mega Man ZX is part of the canon story or simply a gameplay extra. The latter one is what is commonly believed, but there is vague evidence by Flamole during his first defeat, which implies its existence, as he sensed something entirely different from Model W.

Forms and Abilities
Omega has many powerful abilities, which is why he is feared by all, Reploid and human alike. These are unique to each form, total of three forms to begin with.



Normal/Golden Omega
Omega's first form is his original body, the "Devil Reploid". He is at his most recognizable in this stage. This stage later evolved into the Golden state, after he absorbed the Dark Elf, boosting his power stats yet again and granting him the ability to take control of all Reploids on the planet at once. His claw-like hands can detach as Fefnir found out to his cost. The main difference between the original and Golden states is the amount of damage that Omega delivers, and the last saber attack. He's also extremely durable, Fefnir and Leviathan being unable to damage him even when he wasn't fused with the Dark Elf. It should however be noted, that Omega was originally intended to be much more powerful in this form, being a faster and stronger opponent but lost this abilities due to game mechanics which turned him into a seemly motionless, floating enemy that could only move his hands and sword.


 * Hoop Shot: Two arms will constantly rain lasers down and one will fire lasers that can only be dodged by jumping or dashing under them. This makes him extremely vulnerable.
 * Omega Laser: Omega will spawn three lasers in front of his torso. The lasers will hit three certain spots (near him, between him, and at the back of the room) and reflect off them (faster in the second encounter).
 * Piercing Sword: Omega will slam his saber into the ground with enough force to strike player. The third strike will send debris everywhere (second encounter only).



Second Form
Omega takes this form using the full power of the Dark Elf. With three heads (His, X's, and Zero's), a sword so massive the tip can't be seen, and an immense cannon, Omega is a far more formidable opponent., utilize both, and all three heads can fire explosive energy beams. The monster's only weak point is the central face, a relatively tiny target. Despite below strengths and weaknesses, this form pales in comparison to the final form. Again, Omega's movement and attack patterns were limited due to game mechanics and the size of the Game Boy Advance screen.


 * 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 his eyes (X head fires farthest, Omega head middle, Zero head shortest).
 * Exceed Buster: Omega will fire three huge energy shots in a row. Can be dodged more easily with a double jump.
 * Exceed Buster Neo: Omega will fire a laser beam; dash to dodge.
 * Binding Ball: Omega will summon a red sphere, following you and trapping you. If you get caught, it will drag you back to him, dissipating when it touches Omega.



Zero
This form of Omega was resting inside the central head of "Fusion Omega". The original body of Zero, upgraded by Weil to draw out its full power. As seen in concept art, Omega's original form is just a sort of external armor for it. Omega starts off the battle shouting out the catch phrase before his hair sprouts and a white aura resonates around his body. Omega wields a buster hand gun (O-Buster) and a pink-colored saber (O-Saber), both of which are much more powerful than Zero's versions.

He can use most of Zero's attacks from the Mega Man X series, along with the buster combo. Despite powerful ranged skills, Omega truly shines in melee combat. On a larger note, this form of Omega can hit within Zero's invincibility frames, making attacks on Omega while flashing even riskier. All of these techniques make this the most dangerous form of Omega. Despite being much smaller, this form has the same amount of health as his larger forms. As evaluated above, he is also arguably just as strong, if not stronger, than his previous two forms. On a semi-related note, Omega Zero's hair appears only at the immediate start of the battle, implying that Omega Zero, and by extension Zero, is capable of retracting his hair. A similar occurrence exists with the ZX model during the Model W crisis.


 * トリプルスラッシュ (Triple Slash): A regular 3-hit combo with the O-Saber.
 * チャージセイバー (Charge Saber): Omega slams the ground with the O-Saber, causing rubble to fall from above.
 * アークブレード (Arc Blade): - Omega spins in the air with the O-Saber, sending crescent waves in seven directions.
 * ダブルチャージウェーブ (Double Charge Wave): Omega fires two charged shots with his buster, followed by a crescent wave with the O-Saber.
 * 龍炎刃 (Ryuuenjin): - Omega does a rising slash with the O-Saber.
 * 滅閃光 (Messenkou): - Omega pounds the ground, unleashing a spread shot in five directions.
 * 天照覇 (Tenshouha): - Omega pounds the ground, creating vertical beam pillars, rendering him briefly invulnerable (In ZX this heals Omega by 8 units).
 * EX Skill: 乱舞 - Ranbu ("Berserk Dance"): Omega lunges at the opponent and executes a deadly 7-hit combo with his saber. If Zero successfully dashes underneath this move just as Omega Zero leaps, Omega Zero will turn around to Zero's direction and will try to connect the attack.

Other media
In the Rockman Zero, Omega is a normal-sized Reploid that works for Dr. Weil. He has the task to find the Dark Elf, but during his search, he fights against the new Zero in a village and is defeated. Omega attempts to defeat Zero several times, with no success. Because of his failures, Weil gives Omega the Giant Omega-DX to help him defeat Zero, but warns him that if he is not done with it in three days, he will be fired. As Omega's giant robot is destroyed, he is fired and now wanders around the village. Later, Zero saves him from Noble Mandrago, but Omega is not happy to see Zero, as he is the responsible for his current situation. He is last seen trying to defeat a "Dark Elf possessed" Zero (Zero being actually "drunken" because of cola), but Zero defeats Omega by running over him with Neige's car.

Despite their rivalry, Omega and Zero teamed up once to survive against several "zombie" Reploids. Omega has great fear of zombies, even panicking when he sees Weil's face and confuses him with a zombie. Zero also helped Omega build the Giant Omega-DX, not knowing its purpose was to destroy him, but as Zero didn't do his work properly, ignoring several parts, it resulted in the robot's destruction and Omega being fired.

Trivia

 * Omega (uppercase Ω) is the 24th and last letter of the Greek alphabet. Ω is used as the Boss logo through Mega Man Zero 3, but is replaced by W/V (Weil/Vile's symbol) in Mega Man Zero 4. In addition, Omega's "Biometal" in Mega Man ZX is shaped to resemble Ω.
 * A very possible reason for his naming is that "Z" (Zero) is the last letter of the English alphabet, and as said before, "Ω" is the last letter of the Greek alphabet.
 * During the ending sequences of Mega Man Zero 3, Omega Zero actually speaks with a text/dialogue box, although he only has one line. His portrait is seen as similar to Zero's, the only differences present are that Omega's eyes are red and his armor has a deeper hue of red.
 * Before Zero battles with Omega Zero, the latter shouts a Japanese line, "Ware wa meshia nari!" This translates to "I am the Messiah!" Omega Zero uses the same line before the player finds and fight him in Mega Man ZX. This fortifies the fact that many of the characters in the Zero series referred to Omega as "The God of Destruction".
 * This can be assumed as what Zero himself is intended to be in the first place, had he not removed his destructive programming.
 * Considering that Omega is in fact an external upgrade to Zero's original body, it could be considered that technically, Omega is Zero's desired ultimate armor comparable to that of X's.
 * Omega's armor, after fighting him for the first time, emits a glow from the black parts that make up his visor, face, chest, and abdominal region upon defeat, which then seem to heal the armor, and bring the claws upward from the ground back to a levitating position where real arms would be. This could mean that his armor was made with regenerative capabilities. This makes sense in that if the armor were broken, it would have released Omega in his most powerful state (when he was in control of Zero's original body). The regeneration might be to keep the armor active and the armor itself seals and limits Omega's power extensively.
 * Omega's second form's appearance is similar to that of Omnimon from Digimon, with how it has MetalGarurumon's head used as a cannon and WarGreymon's head for the sword, like Omega does with X and Zero's head respectively.
 * Ironically, Omnimon's original Japanese name is Omegamon.
 * Though some fans complain that Zero's original body should appear as it did in the X series, in its bulkier style, it has been officially stated that the differences reflect only the change in art styles. In terms of gameplay, Zero's body appears exactly the same as it always has.
 * With the change in his appearance, Omega Zero's attacks also differed from the original incarnations seen in the X series:
 * The Z-saber combo is slightly altered between the X and Zero series, and Omega Zero uses the latter variation.
 * The Buster Combo is slowed down, and, with good timing, Zero can easily dodge each shot with a jump. And the crescent shot doesn't home in on Zero, not like the most recent incarnation seen in X5 (arguably, an even more recent incarnation is seen in X6, with the Zero Nightmare).
 * In Mega Man X2, a copy of Zero appears wearing black armor, if the player is able to revive Zero. Also, in the Japanese story of Mega Man X2, Zero's new body is a copy of the body that was destroyed in Mega Man X. This holds some similarities to Omega's story.
 * Omega has the most amount of health in the Zero series, and it is only second to Albert (Model W) in Mega Man ZX Advent: Albert has 486 units of health (this is not official info., it was calculated while fighting the boss and shooting Buster Shot shots one-by-one) for his first form and 2 life bars (64 units, 32 each - like normal bosses' life bars) for his second one. While Omega only has nine health bars in total (three for each form.). If one counts Omega's ghost from Mega Man ZX as a form of Omega, he also has a total of twelve health bars.
 * In the background of the stasis chamber during the final battle with Omega, a piece of the rubble is identical to the iconic W of Dr. Wily and on the left, an L is resting on a giant head similar to that of X's head.
 * In the Zero Collection, the player must now attack the regenerative part of Omega to cause damage to him instead of simply attacking from the ground. Omega's invincibility timer is increased slightly, so the player can only do two attacks before the timer takes effect.
 * Although Omega is called "Reploid", this is ironic, as Zero's original body was not a Reploid, but just a highly advanced robot, with the only difference being his "mind". Which would technically speaking make the term Reploid inappropriate for Omega, unless him being another identity in Zero's body counts as being a Reploid. The copy of Zero from Mega Man X2, the Nightmare Zero and Zero's current body are the only three replicate androids (Reploid) which are not based on X's general architecture.
 * It could be noted that Omega is rather a "consciousness" and not a Reploid altogether, being that Omega is using Zero's original body. On top of that, Omega, despite using Zero's original body, does not possess the original Z-Saber, which is in Zero's possession.
 * Despite popular belief, Omega is voiced by Jun'ichi Suwabe and not by Ryotaro Okiayu, Zero's voice actor from the Mega Man X series.
 * Omega Zero's Ranbu is a nod to a Street Fighter attack named the Shun Goku Satsu, a move perfected by Akuma.
 * In addition, Omega also shares some other similarities with Akuma. In addition to having stronger attacks than Zero and Ryu respectively, Omega is often viewed as a devil reploid much like Akuma is seen as a demon, even though the latter does not ever acknowledge himself as one. As Akuma possessed stronger variants of Ryu and Ken's powers, Omega's fusion form seems to somehow parallel this having both Zero and X sections. Though it is not explained as to why Omega's second form had a section resembling X despite having no connection to himself whatsoever, it's possible that he may have absorbed some of X's power when X had the Dark Elf sealed inside him. Regardless, this factor is also somewhat similar to Akuma, who typically shows almost no interest in Ken.
 * Omega is only one of two characters in the series to appear as both the first boss and final boss. The other example is Sigma in Mega Man X5, as Sigma Head.
 * Omega Zero's saber's color scheme is extremely similar to the Saber+2 from Mega Man Xtreme 2.
 * Omega's ranbu also bears a strong resemblance to the Zero Final from the same game.
 * Omega's symbol (Ω) appears in every boss battle since the first Mega Man Zero, even though he didn't appear until Mega Man Zero 3. The symbol was changed to a W (representing Dr. Weil) in Mega Man Zero 4.
