E-123 Omega

"I am Omega, the ultimate E-series robot!"

- Omega


 * For Omega's Archie Comics counterpart, see E-123 Omega (Archie).

E-123 Omega (オメガ), or, technically, E-123 Ω, is a fictional robot from the Sonic the Hedgehog video game universe, first appearing as a fully playable character in the multiplatform game Sonic Heroes, which was first released in Japan on December 30th, 2003. Omega was created by Takashi Iizuka and designed and modeled by Nobuhiko Honda at Sonic Team USA. Omega has helped Shadow (and to a lesser extent, Rouge) in four Sonic games, and while not being a major character, is popular enough in his own right and has established himself as a main character. Recently, however, he has made less appearances and he only seems to be in the mainstream canon games as a teammate to Shadow and Rouge. Although he has been making more appearances in spin-offs such as Sonic Chronicles: The Dark Brotherhood and Mario & Sonic at the Olympic Winter Games and also made his debut in the Archie Sonic the Hedgehog comics' universe in April 2009, so his number of appearances could increase.

He bears a strong resemblance to another character in the series, E-102 Gamma (a possible design inspiration), who is part of the same robotics production line in the series. In the games, he was created by Doctor Eggman, and is out to destroy him due to lack of respect and has a lust for revenge. Omega is 150cm tall (4ft 11in) and weighs a hefty 1,230.512kg (2712.77lbs) making him the heaviest character in the Sonic series. He has the capital Omega symbol (Ω) painted on the front of his left shoulder, in contrast to all the other E-100s, which had lowercase Greek letters. This may be to show that Omega is the most powerful of Eggman's E-Series (though the original set of E-100s from Sonic Adventure had various Greek symbols), or because the character's designer felt that the capital letter was more noticeable and well-known than the lowercase (ω).

Sonic Heroes
Omega is the one hundred and twenty third and last of Doctor Eggman's E-100 series robots, debuting in Sonic Heroes. Omega was designed by Eggman to prevent the release of Shadow the Hedgehog, and, in case he failed to control Shadow when he was released from stasis or someone managed to free him. To accomplish this, Eggman sealed Omega in an abandoned base with Shadow. Being imprisoned infuriated Omega; he decided to prove his status as the most powerful E-Series robot by abandoning his original programming and taking revenge on his creator and all the other machines he built.

When Rouge the Bat went looking for Eggman's secret treasure in his base, she accidentally reactivated E-123 Omega when she released Shadow from a stasis pod. Mistaking Shadow for an Eggman robot and following his new mission, Omega attempted to take out the hedgehog. However, Rouge broke up the fighting long enough to hear both their stories. He soon teamed up with Rouge and Shadow as the power member of Team Dark.

The three of them then started their search for Eggman at Seaside Hill and Ocean Palace before coming face-to-face with the Doctor himself (who was really Metal Sonic in disguise) in his Egg Hawk. After defeating it, they continued on to Grand Metropolis and afterward Power Plant, where they met with the Chaotix. Rouge believed them to be rivals seeking Eggman's treasure, and a brief battle ensued. They then headed to Casino Park and Omega detected enemies two hundred meters ahead of them while Rouge was wondering about the Chaotix. They then went to Bingo Highway and finally met up with "Eggman" again, who set an army of robots against them, but were defeated by Team Dark's combined efforts. Following "Eggman's" energy signature, Omega led them to his ground base passed Rail Canyon and through Bullet Station before confronting "Eggman" again in his Egg Albatross and Egg Hawk combined. They defeated both and discovered that the Eggman they fought appeared to be a dummy that issued a recorded laughing, which angered Omega. The automaton then watched Shadow when he discovered a robot in his likeness before the ultimate lifeform ordered them to move and they proceeded to Frog Forest. After trekking through Lost Jungle, they came across Team Sonic, who were also looking for Eggman, and a fight ensued. Once this was over, Omega led them to Hang Castle on the search for Eggman and through Mystic Mansion. After they escaped the castle, "Eggman" appeared again, but Omega was unable to tell if it was really him or not due to his sensors being jammed. After defeating an even larger army of robots, Team Dark made its way on to the Egg Fleet and finally arrived on Final Fortress. After getting passed the ship's forces, they battled "Eggman" in his Egg Emperor and won, causing multiple explosions to course through the machine. After deeming "Eggman" eradicated, Omega then set about destroying a room full of Shadow Androids Rouge had just entered looking for the Doctor's treasure. The bat then told Omega that Shadow, the one they knew, was a robot (a translation error), and before saying anything else, turned to leave. Then Omega said, with a slight sign of compassion, that in order for there to be clones the original must still exist.



He then accompanied Team Dark to a large tower on the ship in the shape of Eggman, and watched as it was destroyed and the parts used to turn Neo Metal Sonic into the Metal Overlord, though still largely incomplete. He then gathered around with the other three teams as the real Eggman explained that Metal Sonic copied all their data and combined it with the power of Chaos, saying it would help if they had the seven Chaos Emeralds. Fortunately, all four teams had collected the emeralds during their adventures, and Rouge and Omega revealed they had the grey and green Chaos Emeralds respectively. But Eggman still thought it a long shot, so Shadow told Team Sonic that he and everyone else would distract Metal Sonic long enough for them to induce a super transformation using the emeralds' power. After Team Rose and Team Chaotix attacked Metal Sonic from the right and left sides of him, Team Dark struck him from the front by assaulting his weak point that changed to repel the attacks of the three members at the right time. But, fortunately, through team work, they managed to weaken him before he grew wings and took off into the sky. Team Sonic then went into their super states and challenged the Metal Overlord and won. Neo Metal Sonic was then reverted back to his original form, and Omega picked up his deactivated body when everyone was gone and watched Team Sonic, Rouge and Amy Rose run off into the distance with Shadow.

He was voiced by Jon St. John in English and Taiten Kusunoki in Japanese for the entirety of the game.

Shadow the Hedgehog
Omega made an appearance in Shadow the Hedgehog (2005), still with the sole intention of getting revenge on Eggman. He was given a new English voice actor from 4Kids Entertainment (Andrew Rannells) while retaining his Japanese one (Taiten Kusunoki). Omega assisted Shadow in the Hero missions of the "Iron Jungle" and "Lava Shelter" stages by teaming up to get to Eggman and helped him battle the "Egg Breaker" and "Egg Dealer" bosses following those stages. In Expert Mode, he talked to Shadow on the "Mad Matrix" and "Lava Shelter" levels, also being some kind of comic relief in the latter, along with Rouge, and he was heard last giving support to Shadow on The Last Way along with every other main character in the game. In the missions that he appears in, the player must either destroy the Egg Balloon ("Iron Jungle") or head to the center of Eggman's base ("Lava Shelter") to complete the hero mission. Strangely, whether the player completes the "hero" or "dark" mission for "Lava Shelter", Omega will help Shadow fight the Egg Dealer, despite the "dark" mission being helping Eggman. Omega is also playable by inserting a second controller, allowing the player to control him and use Omega to attack certain enemies within a limited distance. Omega is virtually invulnerable in this state, as he doesn't lose rings and deaths mean nothing. He doesn't use any weapons to attack, and merely swipes at opponents with his hands or jumps on them.

Sonic the Hedgehog
Omega appeared in Sonic the Hedgehog with a prominent role in Shadow's story this time voiced by Maddie Blaustein and again by Taiten Kusunoki (mistakenly credited as "Taitem").

Upon being sent to the future by Mephiles the Dark, Shadow and Rouge noticed Omega in standby mode in the "Crisis City" stage. Rouge later goes back to the present alone, where she finds Omega in the ruins of Tropical Jungle, (judging by the throngs of Eggman's robots, it can be reasonably speculated that Omega was in the area to destroy them). Rouge asked Omega to help Shadow out in the future, entrusting him with the green Chaos Emerald they'd found. Omega complied, and went into stand-by mode until the point in the future when Shadow was in trouble. Between then, Shadow was blamed for releasing Iblis by humanity, and, according to Mephiles, they reprogrammed Omega to hunt him down and seal Shadow within a technologically advanced cage. Omega carried out these orders and was then left within Crisis City's ruins until he was meant to help the past Shadow. When the moment finally arrived after waiting two centuries, Omega reactivated and helped Shadow in a fight against Mephiles just when he was in danger, after which Shadow and Omega went back to the present while chasing Mephiles through a time-warping sphere of energy. They met up with Rouge at Soleanna's docks and Shadow headed off to get answers about Mephiles from Dr. Eggman. Omega then went in pursuit of Mephiles himself while Rouge moved to Soleanna's Castle Town and was present when Shadow returned from the past.



Omega located Mephiles at position K31 in Wave Ocean and after getting passed obstacles and defeating numerous enemies, located Mephiles and proceeded to attack him. Mephiles teased Omega by saying that he was clearly made to capture Shadow judging by how easily he could defeat him, and showed knowledge of Omega's capture of Shadow. Before Mephiles revealed everything, Omega proceeded to unload his machine guns on Mephiles, and he disappeared in a black mist. Omega then revealed somewhat sadly to Shadow and Rouge that during his two hundred-year isolation he had been reprogrammed to capture Shadow due to humanity's fear of him and was the one who sealed him in his future prison.



The trio later chased Mephiles to a temple in Dusty Desert and Shadow and Omega navigated through it, trying to reach Mephiles before he could find the Chaos Emerald inside and merge back with Iblis to become Solaris, but they arrived too late. They had taken with them a new Scepter of Darkness and used it after defeating Mephiles, but failed to seal him in it because of his new form made through Shadow's shadow. After blasting all three members of Team Dark off their feet, Mephiles then used his powers, along with two Chaos Emeralds, to summon a clone army of himself. Before finishing them off, Mephiles reminded Shadow of humanity's betrayal against him in the future. Without hesitation, Shadow told him that if the world chose to become his enemy, that he would fight as he always had. Shadow then removed his power inhibitor rings and covered himself and his team in a huge amount of energy and defeated Mephiles and his clone army.

Afterward, Team Dark took view of their handiwork and Shadow attempted to take Mephiles's Chaos Emeralds, only for them to start glowing and transport them all off to a space-time rift created by the newly rectified Solaris along with Silver, Eggman, Tails, Knuckles, Amy, Princess Elise, and Sonic's dead body. Everyone briefly grieved over Sonic's death. Knuckles said that they had to stop Solaris at once, but Eggman informed everyone that Solaris couldn't be defeated in this specific time, since it existed in the past, present and future. Silver suggested that they destroy Solaris all at once, but Shadow countered his argument, saying it was not possible without Sonic's help. Elise then felt Sonic's presence in the wind and Silver realized that they could use the Chaos Emeralds to resurrect him. Omega and the others then spread out over the distant corners of the rift to find the Chaos Emeralds and he traveled to Flame Core, where he found the green emerald near a lake of lava. Once all the Chaos Emeralds were collected, Sonic was revived with Elise's kiss and the power of the emeralds, transforming him into Super Sonic. He then gave this power to Shadow and Silver to transform into their super forms, and together the three hedgehogs defeated Solaris as Omega and the others watched them battle.

Omega is playable in the first boss battle against Mephiles, Wave Ocean, Dusty Desert and the End of the World stages. He is also playable in the various downloadable Very Hard Missions of Shadow's levels, including Kingdom Valley, Crisis City, Flame Core, Radical Train, Aquatic Base, and Dusty Desert. He is also playable in the boss level against the Egg Genesis in White Acropolis which can be accessed after downloading the "Team Attack Amigo" download.

Design Changes


Omega's design was changed considerably, with a taller head and bigger shoulders, along with various small details such as less smooth fingers, (making them look somewhat skeletal), giving him a more humanoid appearance. Omega's frontal black stripe has been replaced with a white/silver stripe, making him resemble E-102 Gamma. The stripe also sticks out much more than in previous games. He has a thinner head, with the eyes closer to the stripe. The flaps on his sides have been given grooves for unknown reasons. And his hands also look sharper and rather run down.

He walks and moves in a slower, more cumbersome manner like an old fashioned robot, compared to his wild, sometimes erratic, human-like movements in previous games. Omega's voice was significantly different from his previous portrayals in Sonic Heroes and Shadow the Hedgehog, sounding much more high-pitched and robotic. Many of the western players of Sonic the Hedgehog blamed this on Omega's new voice actor, the late Maddie Blaustein, and criticized her performance. However, Taiten Kusunoki, Omega's Japanese voice actor, also sounded this way in Sonic the Hedgehog despite voicing Omega exactly the same as Jon St. John and Andrew Rannells, Omega's previous English voice actors, in the passed two games. Furthermore, when Maddie Blaustein voiced Omega again in Mario & Sonic at the Winter Olympic Games, she sounded exactly the same as Omega's previous English voice actors. This evidence suggests that SEGA changed or altered the voice manipulation program used for Omega's voice in Sonic the Hedgehog to sound more robotic, but later reverted it back to normal. Most likely because of poor reception.

Sonic Chronicles: The Dark Brotherhood
Omega is one of the eleven playable characters in Sonic Chronicles: The Dark Brotherhood for the Nintendo DS. In the story, Omega went to Eggman's ruined city of Metropolis to destroy any robots he could find, but he located the Marauders instead. The Marauders had reprogrammed Eggman's old robots to serve them and, upon discovering Omega, sent them to take him apart after he had to make a retreat into a room in North-West Metropolis. The robots were successful, but Shadow was worried about Omega and went in search of him using an old Eggman device that picked up the automaton's signal. After losing it, Shadow then teamed up with Sonic and co. to help find Omega. He was found by Miles Prower and Eggman's team and Omega was repaired by Tails, much to the disapproval of the Doctor. When Omega saw Eggman his first inclination was to attack him, but Tails told Omega that they'd joined forces with Eggman. At first Omega thought Tails had gone mad and suggested destroying him, but Shadow and Rouge confirmed this for the robot. Trusting his friends more than Tails, Omega teamed up with Sonic after recharging himself in the stronghold in the Underground. Sonic Chronicles: The Dark Brotherhood (2008) [After they enter the room with Omega inside.] Shadow the Hedgehog: "Wait! That's Omega! I knew it! Those Marauder goons. We have to--" [Robots enter.] Miles "Tails" Prower: "Later! Someone's coming!" Shadow: "Good. I need to smash something." [...] Shadow: "Omega!" Doctor Eggman: "Oh, don't waste your time on this one. He's been a thorn in my side for years!" Shadow: "Quiet, Eggman, or I promise you I'll--" Tails: "He's still functioning! Just heavily damaged. But I think I can... Yes! With the parts from those guardian robots, I can repair him!" Shadow: "Do it." [...] Shadow: "Omega! Can you hear me?" E-123 Omega: "SYSTEMS COMING ONLINE -- E-123 OMEGA BEGINNING REACTIVATION PROTOCOL." Rouge the Bat: "If I had a nickel for every time I heard that..." E-123 Omega: "EGGMAN DETECTED. BEGINNING ANNIHILATION SEQUENCE." Tails: "No! Omega, Eggman is on our side!" E-123 Omega: "ORANGE FOREST CREATURE HAS GONE MAD. RECOMMEND IMMEDIATE DESTRUCTION." Shadow: "No, Omega. He's right. Eggman is helping Team Sonic against the Marauders." Rouge: "As hard as it is to believe." E-123 Omega: "THERE IS NO REASON TO DOUBT SHADOW OR ROUGE. THERE IS NO REASON TO TRUST THE REST OF THESE MEATBAGS." Tails: "What happened to you, Omega?" E-123 Omega: "I CAME HERE TO DESTROY ALL OTHER EGGMAN ROBOTS. BUT I WAS SURROUNDED BY STRANGE CREATURES AND FORCED TO FLEE. THE COWARDS FOLLOWED ME. THEY MADE THEIR ROBOTS DISMANTLE ME WHILE I WAS HELPLESS. DISASSEMBLED BY INFERIOR MACHINES. IT WAS EMBARRASSING." Shadow: "Come with us, Omega. We're going to destroy the Marauders for what they did to you." E-123 Omega: "YES. THEY WILL BE DESTROYED FOR WHAT THEY DID TO ME." Rouge: "Ugh. Again with the emotionless revenge. It just gets tired." Tails: "Let's go, team!" Eggman: "Yes. We have much work to do!" E-123 Omega: "I MUST TAKE TIME TO RECHARGE BEFORE COMMENCING REVENGE." Shadow: "The stronghold in the Underground, Omega. You can recharge there." Eggman: "I never agreed to allow that faulty machine to--" Shadow: "Silence, Eggman. Now." E-123 Omega: "I WILL GO TO THE UNDERGROUND TO RECHARGE. YOU WILL FIND ME THERE IF YOU NEED ME." Shadow: "We'll get the Marauders for what they did to you, my friend. Let's get to it. The Marauders must pay."

Omega was an optional character and his stripe was returned to his pre-2006 color, but now both of his shoulders have a "Ω" symbol. His main combat move was firing missiles at his enemies which could effect nearby opponents along with the main target when they struck. In combat, Omega had the highest damage power, and the highest armor, but was also one of the slowest and therefore only got one attack per round. He (optionally) provides most of the end credits for Sonic Chronicles, along with Tails and Sonic. Omega also has his own wallpaper which shows Metropolis in the background.

Mario & Sonic at the Olympic Winter Games
Omega appeared in Mario & Sonic at the Olympic Winter Games as a boss or rival character on both the Nintendo Wii and DS versions. His stripe returned to silver for this game. He was voiced by the late Maddie Blaustein in English and Taiten Kusunoki returned to the role for Omega in Japanese.

In the Wii version in Festival, Omega suddenly comes out of nowhere to challenge the character(s) to Speed Skating 500m on Day 5 in Singles and Short Track Relay on Day 9 for Team, saying his defeat was impossible. After the player has beaten Omega, they can buy a suit of him for their Miis for a price of three hundred Star Tokens and the music that plays in the background while challenging him for seventy. The Miis can wear the Omega Suit in the game and it gives them stats that, presumably, would be identical to Omega's own if he were playable. Ironically, Omega's statistics are exactly the same as Dr. Eggman's.



In the Nintendo DS version, Omega plays a small role in the Adventure Tours mode as the first enemy boss of Blitzland and the final member of Team Dark to be fought against. In the story, Omega went on his old mission of defeating Eggman and confronted him in Blitzland, but Eggman said he would only fight Omega if he proved himself worthy by defeating Sonic and Mario, so Omega stationed himself in Blitzland near some storage tanks and waited. Eventually, Sonic and Mario appeared and Omega challenged them to Intense Short Track, but inevitably lost. He then confessed why he fought them and teleported back to the skating course in a black vortex to practice before Sonic, Mario or Toad could get a chance to make Omega their ally. The player can go against Omega again by either selecting the fight against him on the Mission List or by visiting his post, despite him being no longer visible, by interacting with the board there. Despite gaining new artwork for Mario & Sonic on the Wii version, the artwork used for Omega on the Nintendo DS comes from Sonic Heroes.

Miscellaneous
Omega is briefly mentioned by Rouge during Sonic Battle, when she notes the similarities between him and E-102 Chaos Gamma after defeating him.

Omega's artwork and screenshots from Sonic Heroes can be seen in the "museum" of Sonic Gems Collection and Sonic Mega Collection Plus.



Omega-like robots appeared in a McDonald's miniature videogame along with Shadow that for a time came free with Happy Meals. It was part of a series of McDonald's sport-themed Sonic games were the Omega robots and Shadow were playing a game of hockey and Shadow tried to get hockey pucks past the Omega robots who acted as goalies, starting with one Omega on the first level, and then three on the final one.

Omega appears on two collectible cards in Sonic Rivals and Sonic Rivals 2, namely the "E-123 Omega 2006" card and the "Team Dark 2003" card.

According to Gamesmaster magazine, Omega was supposed to be playable in Mario & Sonic at the Olympic Games, along with Silver the Hedgehog, Rouge the Bat, Cream the Rabbit, (who was later changed to a referee), and Donkey Kong. All of these characters, except Rouge and Omega, can become playable through hacking, along with Jet the Hawk, Big the Cat, a Kiki, Birdo, a Goomba, an Egg Pawn, a flying Egg Pawn, a Bullet Bill, a Boo, Espio the Chameleon, Charmy Bee, Lakitu, Toad and a Bandit.

Omega appeared in Super Smash Bros. Brawl as a collectible sticker.

An alternate universe counterpart of Omega, called the Omega Care Unit, appeared in Sonic the Hedgehog #193, #194 #195, and #196. It is a special medical suit created by Dr. Ivo Kintobor to help Buns Rabbot with her NIDS, the same disease Maria Robotnik had. Buns also uses the suit as a means of protecting Dr. Kintobor until he can find a cure for her, much to the doctor's displeasure. The suit was partially destroyed, however, during a battle with Rosy the Rascal. The suit was rebuilt by Dr. Kintobor and Buns was later seen using it again. Buns has also made references to Omega as in-game jokes. For example, during the fight with Rosy, she complains that the care unit's weapons aren't very powerful and says "Ah wish ah'd been outfitted with somethin' a bit more proactive...like a missile launcher or somethin'." - an obvious reference to E-123 Omega, who has a missile launcher.

During the Empire City stage in the Xbox 360 and PS3 versions of Sonic Unleashed, players can see street signs with the names Shadow Ave, Rouge St, E-123 Omega Rd, Silver Beach, West Park, Chao Garden and Blaze Rd.

It is currently unknown if Omega will appear in the rumored Sonic Chronicles 2. But due to the fact that he was only an optional character in the first one, it is difficult to predict.

Concept & Design
E-123 Omega was created by Takashi Iizuka, director of Sonic Heroes, the game Omega debuted in. Omega was likely made to be a "filler character" for Team Dark in Sonic Heroes since no previous character would fit the role, or possibly because Iizuka didn't want to bring too many old characters, and continued the tradition of adding a new one each game.

Omega was concepted by Takashi Iizuka, and was possibly assisted in designing him by Nobuhiko Honda, Sonic Heroes's player designer. It appears to have been made with the intention of fitting in with the rest of the E-100 Series robots from Sonic Adventure (particularly Gamma) while making him stand out by giving him a stockier upper body and arms with different coloured eyes. His height is also lesser than the other models and his shoulders larger with a visible Greek symbol on the front of the left and back of the right with red handlebars on the top. They also decided to go without the twin exhaust pipes and grav-linked jet disc ("Jet Booster" in Sonic Adventure) of the first E-100 Series robots, instead settling for one circling pipe around the waist with two flaps attached and having twin jets installed in Omega's back below the hunch. The stripe running from his head to stomach has also been changed so that it is a seperate piece of metal altogether and not simply painted on like the others and he also has one extra finger and two hands with yellow wrists studded with large spikes like a dog collar. Just below his stripe is a plate of clear material that allows others to see some of his inner workings, but this is often coloured blue or white.

Personality
While Omega, as a robot, is largely emotionless, he is capable of understanding those of others, and reacting appropriately. For example in Sonic Heroes, when Team Dark is lead to believe that Shadow may be an android created by Eggman, Omega comforts a depressed Rouge (albeit in a distant, matter-of-fact matter) by saying that they needed the original to make a copy, thus meaning that the real Shadow is still alive. In Sonic Next Gen, he shows depression and anger when Mephiles reveals that Omega is the one who will trap Shadow in the future after the world uses Shadow as a scapegoat for Iblis' mass destruction. It is also possible Omega is superstitious, as he believes in omens such as the appearance of stormy weather, though this might have been because of his scanners picking up a powerful magnetic field.

Like E-102 Gamma, Omega has a free will and a personality. However, he is considerably less noble than Gamma; while Gamma destroys only what needs to be destroyed, Omega destroys anything that could possibly pose any kind of threat to himself or his mission. From his quotes, he thinks other Eggman robots are inferior to him, dismissing them as "worthless consumer models", especially the E-2000 model. He hates side tracking especially when it comes to locating Eggman. Omega is also very proud and feels embarrassed after he is defeated by less powerful Eggman robots.

It also seems that he lacks any sort of negativity towards Sonic and his friends, and didn't even recognize them during their first meeting in Sonic Heroes, as can be heard when the player finishes the Team Battle using Omega. This is probably because Omega was made to contain Shadow the Hedgehog and not as a means to defeat Sonic.

Omega's only goals in life are to take revenge on Eggman for disabling him, and destroy the doctor's other robots to prove himself superior. At one point in Shadow the Hedgehog, Omega made a comment about how he would "reign supreme". Some fans have taken these words quite literally, and believe that Omega wants to take over the Eggman Empire and become a robot overlord in the style of Metal Sonic. However, subsequent games have shown this less believable, and it is generally taken to mean that he wishes to reign supreme as the greatest of Eggman's robots, although it should be noted that the Sonic cast acted rather out of character in Shadow the Hedgehog.

Omega is fairly loyal and dependable when you're on his good side, a bit of a holdover from his original purpose as a servant, and he's not incapable of looking past differences to forge alliances. He also genuinely cares for Shadow and Rouge as friends, and accepts the truth of what they say to him over everyone else; for example, in Sonic Chronicles: The Dark Brotherhood, when the party encounters him, he tries to attack Eggman the moment he sees him, and Tails attempts to convince him that Eggman is on their side; Omega then believes that Tails has gone insane and decides to attack him as well, and he only believes that Eggman is working with them when Shadow and Rouge tell him so.

Stereotypical of most robots, Omega tends to use somewhat lengthy words instead of usual human speech. An example of this is when he uses "Negative" or "Affirmative" instead of simply saying yes or no. Although he has been known to use typical human speech before, such as one of his hint ring lines from Sonic Heroes: "Looks like those guys are guarding that case."

Notably, in all of his appearances (barring the 2006 Sonic the Hedgehog game, in which he behaved in a very odd manner stereotypical of old robots), he makes odd, often erratic movements, such as spinning his head (as if it's on a 360 degree axis) in many circles, and spinning during confrontations of Eggman in Shadow the Hedgehog. Whether this is a programming flaw or intentional is not revealed. Also in Sonic 06, when Omega is standing still, he makes odd movements as if he's doing warm up exercises.

Abilities
Omega has a huge array of extremely destructive weapons concealed in his arms, (somewhat similar to that of Grounder from the Adventures of Sonic the Hedgehog cartoon), including two rapid-fire machine guns, (Omega Machine Gun), two flamethrowers, (Omega Fire), two missile launchers, (Omega Missile), two unusual weapons that fire exploding drills, and energy cannons similar to those used by the E-2000 robots in Sonic Heroes and likely many more. However, unlike E-102 Gamma, Omega is somewhat inaccurate, (despite the fact that he has some kind of special targeting system), most notably when he is firing many shots in every direction with expectations that some of them will hit. He can also rapidly rotate his hands in order continue the spinning of Shadow and Rouge while he holds them, either using the two as melee weapons or firing them as fireballs while in the middle of a jump, (Omega Bazooka). He can perform a similar move without Shadow and Rouge were he just fires destructive fireballs directly at enemies (Omega Launcher). This can cause multiple attack damage to an enemy within a single use. Another ability is his Lock-On Shot which allows Omega to lock-on to a number of surrounding enemies, then release to attack with a Homing Laser. In Sonic Chronicles: The Dark Brotherhood, he has two new abilities called Beam Cannon and Temporal Field. With Beam Cannon, Omega fires a powerful yellow laser at his enemy, in turn reducing certain enemies health points by a considerable amount. And he can deploy a purple energy sphere that phases an ally (or himself) and makes that ally hyper with Temporal Field. It has been confirmed that Omega carries gun magazines, as shown in Sonic the Hedgehog. Omega can also utilize jet boosters built in his back to help accelerate and hover. Also in Sonic the Hedgehog, he can fire Omega Shots (possibly bullets or lasers) using his wrist guns to blow away anything in close range. It's possible he is also armed with exploding rounds for his machine guns, as evidenced by all the explosions he caused to the base he was sealed in by only firing bullets for a few seconds.

The following is a list of all of Omega's POW moves in Sonic Chronicles: The Dark Brotherhood along with descriptions of their functions:

Like most Sonic characters, but unlike most robots, Omega can jump and turn in a ball, known as the "spinball jump" or "spin attack"; he can also grind on rails like most characters but unlike most robots. Omega is also somewhat fast due to a pair of jet engines located on his back, (fast enough to keep up with Shadow and Rouge to be more precise), that apparently can be used for floating (which he does along with Shadow and Rouge, calling it the Triangle Dive) and can also use to jump into the air, and hover. In Sonic 2006, Omega could jump and hover by repeatedly pressing the jump button. By mashing the jump button after jumping, the player could hover for much longer periods. This can be taken advantage of in Wave Ocean and allows Omega to go throughout all that area of the level by using various tall structures and obstacles. His walking speed isn't very impressive, but can be boosted by approximately 15% with adamantium double-lubricated actuator joints installed. He has also displayed considerable physical strength. Being a robot, Omega is able to resist strong blows with his remarkably tough armor, certain forms of poisonous gas, psychic manipulation and electrical currents that most of the other characters cannot pass through.

In Sonic Heroes, Omega is able to use his team's Team Blast, "Chaos Inferno", with Rouge and Shadow, which involves Rouge holding up Omega while he blasts everything around him with large purple energy beams and Shadow stops time with Chaos Control.

In Sonic the Hedgehog (2006), he displays new built-in arm weapons that can fold out eight semi-automatic guns all around his wrists instead of just replacing his hands with them. He was also able to replace his hands with two powerful black Miniguns in the same game instead of silver like in Sonic Heroes.

Omega appears to be water proof as he doesn't short circuit in Frog Forest, Lost Jungle or Charyb's lair when it's full of water, but he does die when he falls into the water of Wave Ocean like many other characters in Sonic 2006. Omega has scanners that allow him to examine both machinery and living beings. He is also equipped with some kind of built in sensor that allows him to locate enemies, life forms and other various objects such as switches. Like all "Power types" in Sonic Heroes, Omega is also able to drive.

Weaknesses
Omega, though one of the more powerful characters, has a few flaws that have hindered him, and may do so again in the future. It is likely that he cannot swim, so water may pose a problem. He is also one of the slowest characters in the series, which makes him an easy hit should he come in contact with a foe such as Sonic, which is surprising as he was made to capture the equally fast Shadow. However, his speed increases considerably when he uses his jet boosters. Weirdly if one were to run too far ahead of Omega as Shadow in Sonic the Hedgehog he could easily catch up before slowing down again. Although his strength is great and his weapons can cause significant damage, they can't destroy certain materials like gold. Some of his weapons, however, may be exempt to this.

Omega is also known to act before thinking, usually charging head-first into battle without any given strategy. This is Shadow's theory of how he could have been captured in Metropolis by the Marauders, in Sonic Chronicles: The Dark Brotherhood.

He may also have a faulty or nonexistent targeting system, explaining his reliance on spreadfire weapons and explosives. This is more easily seen in Sonic Heroes, where he doesn't even appear to be trying to aim until the camera shifts to his point of view.

At the end of a level in Sonic Heroes, Shadow the Hedgehog, Sonic the Hedgehog, and Sonic Chronicles: The Dark Brotherhood Omega's torso spins around. It is unknown if it is a glitch or done on purpose, but may indicate Omega may need a few tweaks as has been stated.

Upgrades
In Sonic Chronicles: The Dark Brotherhood, Omega can be equipped with a large amount of claw and hydraulic upgrades that can only be used by him.

Claws
Below is a full list of all of Omega's claw upgrades in alphabetical order along with information about what they do and their stats. None of them appear until the fifth chapter of Sonic Chronicles when Omega becomes playable.


 * Blunt Claws: Standard grade work claws. Slightly increases damage.
 * Cursed Claws: Prototype combat claws. Difficult to control, but very powerful. Very greatly increases damage. Attack -2, Defense -2.
 * Grapple Claws: Standard grade, durable and reliable combat claws. Moderately increases damage. Attack +2.
 * Iron Claws: Extra durable work claws combine protection with power. Moderately increases damage, slightly increases armor.

 * Spiny Claws: Needle-like claws that tear through steel. Greatly increases damage.
 * Titanium Claws: Master grade combat claws providing superior overall combat power. Greatly increases damage. Attack +2, Defense +2.

Hydraulics
Below is a full list of all of Omega's hydraulic upgrades in alphabetical order along with information about what they do and their stats.


 * Dura-Hydraulics: Double reinforced parts for maximum durability. Greatly increases armor.
 * Iron Hydraulics: Hardened metal for durability and greater hitting power. Moderately increases armor.
 * Master Hydraulics: Premium grade materials providing the best defense and armor. Greatly increases armor. Defense +1.

 * Rusty Hydraulics: Leftover parts from disassembled E-100 series robots. Moderately increases armor but decreases defense. Defense -2.

Relationships
Omega rarely shows feelings other than cold hatred, very different from Gamma's calm and obedient personality, but there are a few occasions where he seems to care about other people.

Team Dark
Omega's closest and only friends are his team members, Shadow and Rouge, though he didn't care much much for them originally.

Shadow the Hedgehog
Shadow and Omega are close allies. In fact, Shadow is perhaps Omega's closest friend and is even seen worrying over his well being, (which is quite odd for Shadow as he usually keeps a tight lid on his emotions), it is possible that this is because they were both prisoners of Dr Eggman (in different ways).

In Shadow the Hedgehog, Omega does not attempt to stop or destroy Shadow when Eggman claims that Shadow is an android that he created, despite Omega's hatred of other Eggman robots. This is further shown in Sonic the Hedgehog where Shadow and Rouge encounter Omega in the future in standby mode. After Rouge notes that they can't do anything for him, both of them seem to show reluctance about leaving. Also, in Sonic the Hedgehog, Omega shows anger at Mephiles' hinting of Omega's future betrayal towards Shadow, and proceeds to attack him. Omega then shows sadness while revealing that his mission in the future was to capture Shadow.

In Sonic Chronicles: The Dark Brotherhood, Shadow joins Sonic's team to find Omega, even calling Omega his friend and showed respect towards him, (which is most irregular for Shadow), and shows anger if you refuse to rescue him. He also joins up with Omega to perform a POW move called Focus Field, where the two of them strike an enemy together, with Shadow using Chaos Blast and Omega attacking with his machine guns. Shadow also teams up with all three members of Team Dark to perform another POW move called Metal Storm, which involves Shadow levitating Omega into the air and Rouge kicks him at an enemy.

Omega and Shadow also seem to have a friendly rivalry of who is the more powerful, similar to that of Sonic and Knuckles, with Omega believing the title belongs to him. Technically, Omega is right in the fact that he has more physical power than Shadow, but which of the two is a better fighter is not confirmed. Shadow is the ultimate lifeform, but Omega is not a life form, so it is really a toss-up. They seem to be evenly matched in their only battle when they first meet in Sonic Heroes, but it is revealed in Sonic 2006 (as well as implied in Sonic Heroes) that Omega was made to contain Shadow from escaping Dr. Eggman's base where he was being held and actually captured Shadow in the future, so it's likely that Omega could defeat Shadow like he did in Sonic 2006, though judging from their friendship, and the possibility that Omega would be reprogrammed to hunt Shadow without question, Shadow would most likely hold back attacking one of his closest friends.

Rouge the Bat
Omega is very loyal to Rouge. He usually follows her orders without question and is also quite caring about her (mainly because she freed him from his prison along with Shadow). This is shown at the end of Sonic Heroes, in which Omega comforts an upset Rouge &mdash; albeit in a distant, matter-of-fact manner. However, as a robot, Omega is generally void of emotion, so this is possibly all he could do to comfort her.

They first meet in Sonic Heroes after Rouge stopped Shadow and Omega from destroying each other to hear both their stories. She convinces the two of them to join forces to find Eggman since that is their united goal. While searching for the doctor, Rouge becomes fond of the robot and they become friends fast. Omega also lets her sit in his hand during their victory poses.

In Sonic Chronicles: The Dark Brotherhood, she supports Shadow's joining because she doesn't want Omega to be alone. She shows that she has got tired of Omega's serious nature, him always wanting revenge and her having to listen to him ramble on about it constantly.

She is part of Omega's POW move called Blazing Tornado, where he covers Rouge in fire with his flamethrower and she then kicks an enemy with fire damage. She also teams up with both Shadow and Omega during Shadow's Metal Storm POW move, where Shadow levitates Omega into the air and Rouge kicks him at an enemy.

Doctor Eggman
Eggman is both Omega's creator and greatest enemy. Omega is constantly trying to get revenge on the doctor for imprisoning him and will do whatever it takes to prove himself superior to Eggman's other machines. However, Omega has passed up his feelings of revenge when he is needed to take out a bigger threat, such as the Metal Overlord, Solaris and the Marauders.

Eggman doesn't seem too concerned about Omega trying to destroy him and merely thinks of him as a "thorn in [Eggman's] side". In fact, Eggman hasn't really been seen interacting with Omega at all. And the few times he has been, like in Shadow the Hedgehog, could be considered non-canon. He does seem to think Omega is capable, however, as he thought he could defeat both Sonic and Mario on his own in Mario & Sonic at the Olympic Winter Games.

Metal Sonic
The two might have only met once but the fact that Metal Sonic is one of Eggman's robots indicates that he and Omega are definitely enemies, (even going far enough for Omega to pass up his feelings of revenge).

They first meet in Sonic Heroes (after Omega finished destroying a room full of Shadow Androids), where Omega helped to defeat Metal Sonic after he turned into the Metal Overlord along with his fellow team members. He is later seen exchanging looks with Shadow and holding a deactivated Metal Sonic in his arms. It is unknown what they did with Metal Sonic or how Eggman Nega managed to get Metal and take control of him in Sonic Rivals.

Nocturnus Tribe
Omega had a brief encounter with the Marauders, but seeks revenge against them after they disabled and humiliated him by taking him apart with inferior machines. He doesn't seem to want vengeance on Shade the Echidna though. Most likely because she left the Nocturnus and Omega decided that she wasn't a foe.

Mephiles the Dark
Mephiles was one of Omega's greatest enemies, (possibly coming second to Doctor Eggman himself). They first met when Omega saved Shadow by distracting Mephiles with his machine guns in Flame Core after coming out of standby mode in Crisis City. They then engaged in battle and Omega and Shadow proved victorious. Mephiles then escaped to the present with Shadow and Omega in hot pursuit. Mephiles escaped but Omega and Shadow kept looking for Mephiles.

Omega later found and defeated Mephiles once again in Wave Ocean. Mephiles then revealed to Omega that he knew the he was the one responsible for imprisoning Shadow in the future. Enraged by this, Omega then proceeded to attack Mephiles with his machine guns. He then revealed this to Shadow and Rouge.

Omega then set off with the other members of Team Dark into Dusty Desert, determined as ever to seal Mephiles before he can merge with Iblis. He and the others arrived too late, and then engaged Mephiles in a final showdown. They proved victorious yet again, but they failed to seal Mephiles using the new Scepter of Darkness. Mephiles then created an army of copies of himself, and Team Dark destroy them (presumably) while Mephiles escapes.

Later, Omega and the others were transported to a time-space rift by Solaris along with Silver, Amy, Tails, Knuckles, Eggman, Princess Elise and Sonic's dead body. Omega then helped the others retrieve the Chaos Emeralds to save Sonic's soul by searching for one of them in Flame Core. He later watched Sonic come back to life, and remained on a monument transported from Soleanna as Super Sonic, Super Silver and Super Shadow erase Solaris from existence, thus erasing Mephiles from existence as well.

E-Series
Omega harbors a deep hatred to all of the E-Series robots, (especially the E-2000 which Eggman began working on shortly after shutting Omega down.) Omega is determined to destroy all the E-Series and any other of Eggman's robots which he dismisses as "worthless consumer models".

E-100 Series
The E-100 Series are Omega's predecessors. Although he has never actually been seen with any of his "brothers," Omega does indicate that he knows of their existence and he thinks them as his inferiors. It is unknown if he bears any hatred towards them, but it's unlikely, partly because they've all been destroyed.

During Sonic Chronicles: The Dark Brotherhood, Omega is repaired by Tails using old robot parts from the disassembled E-100 Series that were installed in Eggman's old flying Laser Drones that had been reprogrammed to serve the Marauders.

Sonic and friends
Although Omega has worked with Sonic and co. on numerous occasions, according to Sonic Chronicles: The Dark Brotherhood he only helps them because either Shadow or Rouge are involved in the matter. He doesn't think much of Sonic and his team, and mainly refers to them as "MEATBAGS."

He lacks any real relationship with any of them and it is likely several of them don't even know who he is, as Omega is one of the few characters in the series to barely have any social interaction with Sonic and his friends. In fact, the closest interaction he's had with any of them is when Tails repairs Omega and when he partners up with Big for the move "Wrecking Ball" in Sonic Chronicles, which could be considered non-canon since he is only optional and plays no major part in the story, so his largest canonical interaction would be when he fought teams Sonic and Chaotix.

This lack of interaction is most likely due to the fact that Omega is a "Team Dark-exclusive" character, only appearing as a playable character in games and storylines that involve both Shadow and Rouge, whom both only have minor interactions with Sonic and friends. Excluding Sonic Adventure 2, Sonic Battle, Sonic Riders, Sonic Rivals, Sonic Rivals 2 and Sonic Riders: Zero Gravity.

G.U.N.
Omega seems to lack any negativity towards G.U.N., and doesn't seem to want anything to do with them, such as in the game Shadow the Hedgehog, where he tells Shadow to ignore the G.U.N. robots in the Iron Jungle stage (but this may be because he was more concerned with finding Eggman or actually cared about them being destroyed). He does however, seem to look down on human government affairs, and sees them as a nuisance (if anything).

Although some speculate that he is a member of G.U.N. like his friends since Rouge asked them for his location in Sonic 06, but this has yet to be confirmed. Although he does join GUN in the Sonic the Hedgehog comics series.

Archie Sonic the Hedgehog comics
Omega appears in the continuity of Archie Comics' Sonic the Hedgehog comic series. He first appeared in issue 3 of the spin-off comic Sonic Universe in February 2009. This version of Omega was activated by Doctor Eggman in order to track down and destroy E-102 Gamma. Omega, the "walking arsenal", battled Gamma's sleeker "assassin" model. Before Omega destroyed Gamma, Gamma uploaded some computer code to Omega that Gamma referred to as his "soul". The feedback from this transfer made Omega uncertain of his purpose. He subsequently joined Shadow the Hedgehog and Rouge the Bat as members of G.U.N.'s Team Dark, dedicating himself to battling the Eggman Empire.

An alternate universe version of Omega from Anti-Mobius has also appeared, known as the Omega Care Unit. This version actually predated mainstream Omega's appearance in the comics, appearing in Sonic the Hedgehog #193. The Omega Care Unit is a non-lethal suit worn by Buns Rabbot to prolong her life after she developed Neuro-Immuno Deficiency Syndrome. The Omega Care Unit looks different from mainstream Omega, being colored blue and having the peace sign on both of its shoulders instead of the capital Omega symbol (Ω) on just its left.

Reception
Omega has a mixed reception from fans. Some see Omega simply as a bad remake of E-102 Gamma, that he is just a filler for Team Dark, saying that both Gamma and his story are much more complex than Omega, although some like that because they think quite a few Sonic characters are too complex, like Shadow the Hedgehog for example. Some see him as a fun character not really needed to the plot and acts as a sort of comedy relief to the games he's in. Fans also think of Omega as not being very developed because he seems to add nothing to the series besides trying to kill Eggman endlessly.

After his debut in the Archie Comics, some criticized Omega seeming too Human and less robotic and felt him gaining a "soul" was rather cheesy, but others felt that it was better than how he got his sentience in the games and made him actually have an appreciation for the feelings he had, rather than just gaining them out of anger.

All in all, Omega is a character who has little fan base, but few people view the character in a negative manner.

Voice Actors
English
 * Sonic Heroes - Jon St. John
 * Shadow the Hedgehog - Andrew Rannells
 * Sonic the Hedgehog (2006), Mario & Sonic at the Olympic Winter Games - Maddie Blaustein

Japanese
 * Sonic Heroes, Shadow the Hedgehog, Sonic the Hedgehog (2006), Mario & Sonic at the Olympic Winter Games - Taiten Kusunoki

Performances
The recordings of Omega's voice actors are all edited with audio programs to give him a more robotic voice, but the performances are different and sometimes the program used on his voice is changed. When Taiten Kusunoki voice acts Omega, he does it in a monotone and deep voice that sounds even more robotic and distorted than the English voice actors. The only exception to this is Sonic the Hedgehog, where his natural voice comes through much more strongly due to the change in audio editing and the only changes are that his voice is echoed. He talks more slowly during Sonic Next Gen, most likely to better synch with Omega's slower movements. Omega's first English voice actor, Jon St. John, gave Omega a deep, monotone yet naturally paced voice. When Andrew Rannells took over, he spoke much slower as Omega, presumably to make him sound more robotic. Maddie Blaustein's initial performance incorporated the use of a different voice program in Sonic the Hedgehog, so Omega's voice was high-pitched and echoed instead of deep and layered. When she voiced him in Mario & Sonic at the Olympic Winter Games, the original voice program was put back in to use and her performance closely mirrored that of Andrew Rannells.

Trivia

 * In Sonic Heroes, Omega has a purple aura around him while jumping. In Shadow the Hedgehog, it is red. In Sonic the Hedgehog he has no aura, and simply jumps using his jets, without spinning. In Sonic Chronicles: The Dark Brotherhood, he just jumps without spinning or the use of his jets.
 * In Sonic Heroes, using the metal character cheat in two player mode, (which can also be used in one player mode through hacking on the computer version), still affects Omega despite the fact that he is already made out of metal.
 * Omega is the only playable character in Sonic Heroes to not have appeared in the anime Sonic X or its comic spin-off.
 * It is possible that Omega is not powered by an animal like the rest of the E-Series robots (with the exception of E-121 Phi) as he was in standby mode for over two hundred years in Sonic the Hedgehog, therefore the animal would have died by then (although he does mention something about a back-up power source).
 * In the Xbox 360 version of Sonic the Hedgehog, in the scene where Shadow and Omega return from the future, if you look closely above the purple portal you can see Omega on top of it before he comes out of it.
 * Sonic Chronicles: The Dark Brotherhood marks a great deal for Omega. It marks the first time he's ever been playable on a handheld Sonic game, the first time he hasn't had a voice actor in a game he's playable in, the first time he's ever been playable outside a main series game and his first appearance on the Nintendo DS.
 * After you win a battle with Omega in your team in Sonic Chronicles, he turns his upper body around and the stripe on his torso is replaced by a thin line.
 * The capital Omega symbol (Ω) on Omega's shoulder keeps changing. In Sonic Heroes and Shadow the Hedgehog, the Omega symbol is on the front of his left shoulder and back of his right, in Sonic 06 it's just on the front of his left and in Sonic Chronicles it's on both sides of his shoulders.
 * During any battle in Charyb's lair when it's flooded, the player can see air bubbles coming out of Omega even though he can't breathe.
 * Many people believe that Omega's stripe was originally white/grey/silver when it is actually black. This is because of how shiny the characters were in Sonic Heroes and Shadow the Hedgehog, so what they were actually seeing was the shine off of Omega's stripe instead of the actual color. This does not include Sonic 06 where it actually is white/grey/silver.
 * The term "Meatbag", one that Omega used on several occasions in Sonic Chronicles: the Dark Brotherhood, is well known for being used by HK-47 who debuted in the game Star Wars: Knights of the Old Republic in 2003, another game developed by BioWare. Coincidentally, Omega and HK-47 made their worldwide video game debuts in the same year. They also believe themselves superior to other robots and like to participate in acts of violence. It should also be noted that since 1999, "meatbag" has been used repeatedly by Bender, another robot, of the sci-fi animated sitcom Futurama.
 * Omega's first voice actor, Jon St. John, was also the voice of Big the Cat, Chaos Gamma and Duke Nukem from the series of the same name. By coincidence, Duke Nukem is yet another "gun toting" and destruction loving character.
 * Omega's second voice actor, Andrew Rannells, also voiced Gamma in Sonic X, though his voice of Omega was different from Gamma's higher pitched Sonic X voice and sounded remarkably like Jon St. John's, making many fans believe it was the same person.
 * Omega's third voice actor/actress, the late Maddie Blaustein, was also the voice of the President, E-10000G, E-10000R, the Babylon Guardian and Meowth from Pokemon. With her now deceased and the majority of the Sonic characters being re-cast, it is currently unknown who will take over Omega's voice when/if he appears again.
 * Omega is the only "Amigo" character in Sonic the Hedgehog to fight in a boss level. (He fought Mephiles the Dark in the Flame Core level along with Shadow.)
 * Omega and Shadow could be considered to be relatives since Shadow was created by Eggman's grandfather Gerald, and Omega was created by Eggman.
 * Many fans believe that the song "Waking Up" by Julien-K, (the theme song for the "neutral ending" of Shadow the Hedgehog), is also meant for Omega as well as Shadow, as some of the lyrics also describe certain characteristics of Omega.
 * After the events of Sonic '06, Omega's capturing of Shadow is apparently erased from time, but it is currently unknown if the erasing of Iblis from history canceled this future event, as it was Shadow whom the world used as a scapegoat for Iblis's reign of destruction as they feared his power, so they could do it again with a different terror.
 * Omega was probably removed from the final story of Shadow the Hedgehog because Shadow was supposed to defeat Black Doom without an ally character, and all the others were frozen to the spot thanks to a Black Arm gas that petrifies organic beings, (minus the Black Arms themselves and beings with Black Arm DNA). Since Omega is a robot, he would have been immune to the effects of the gas and ruined the ending of the game. In terms of story, this could be jotted down to him simply not caring about the current events at the time. He also technically was not part of the story proper, as he only took part in the final neutral levels that ended with Eggman's death which clearly didn't happen, which also had nothing to do with the Black Arms, and could have been considered a completely different plot from the main one.
 * Omega's victory poses always involve him either spinning or turning his torso. It is unknown if this is done on purpose or is a glitch in his programming, but it is probably on purpose because in Sonic Heroes he spins while using his flamethrowers or machine guns.
 * Omega, Cream the Rabbit, and all three members of Team Chaotix are the only recurring playable characters to not get their own personal theme song.
 * Omega was featured in Sonic and the Black Knight on three pieces of winning artwork made by fans.
 * It is probable that Omega doesn't know he was made to contain Shadow as he didn't even know who he was in Sonic Heroes.


 * In Sonic Heroes, Omega is the only Power-Type who is not organic, as well as the only playable character who was introduced in the same game.
 * In Sonic Chronicles: the Dark Brotherhood, Omega is the only member of Team Dark to not be affected by the brainwashing of the Voxai Overmind, possibly because he is a robot.
 * Omega is the only Team Dark member not in the Last Story of Shadow The Hedgehog.
 * Omega is the only ally in Shadow the Hedgehog to not receive new artwork unique to that game. This does not include the icon used for his mission in Iron Jungle and Lava Shelter.
 * If Omega falls into the canals of Soleanna's Castle Town enough times, he will reappear at Shadow's side and die like he does after being attacked by an enemy with no rings. Flashes of light and yellow electricity appear around him when this happens.
 * Mario &amp; Sonic at the Olympic Winter Games was Omega's first appearance on a Nintendo Wii game.
 * While Omega is not playable in Mario and Sonic at the Olympic Winter Games, the suit designed after him (which mimics Omega's stats) reveals that Omega would, surprisingly, be classified as a Skill type, despite Omega being faced in a speed-orientated event and being classified as a power character in Sonic Heroes.
 * Also, ironically, Omega has the exact same stats as Eggman.
 * In Sonic Chronicles: The Dark Brotherhood, Omega is the only character with equipment unique to him.
 * Performing the voice of Omega was one of the final roles ever played by Maddie Blaustein.
 * In the Nintendo DS version of Mario & Sonic at the Olympic Winter Games, when Omega runs low on stamina, he can be seen sweating.
 * Omega seems to have significant knowledge of the Shadow Androids Eggman was employing, as he immediately assumed Shadow was one of them when first laying eyes on him, and also told Rouge that they were made through cloning when she discovered a room full of them.
