E-123 Omega

E-123 Omega (Ｅ－１２３ "オメガ") is a fictional robot from the Sonic the Hedgehog series. He is considered a spiritual successor to E-102 Gamma who is part of the same robotics production line in the series. He was created by Dr. Eggman as the last and most powerful E-Series robot, and is out to eliminate him due to harsh mistreatment and lust for revenge.

Omega was created by Takashi Iizuka at Sonic Team USA. Omega has helped Shadow (and to a lesser extent, Rouge) in several games and while not being a major character, is popular enough in his own right and has established himself as a main character.

Concept and creation
E-123 Omega was created by Takashi Iizuka, director of Sonic Heroes, the game Omega debuted in. His design 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 colored 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 the Jet Booster from 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 separate 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 colored blue or white in-game or in artwork.

Design changes
Omega's design was changed in a variety of subtle ways for Sonic the Hedgehog; His overall look seems to have thinned him out whilst making him look taller, giving him a more humanoid appearance. The yellow casing for his "head" was treated much the same and also brought his eyes closer together. His shoulders almost doubled in size and look more square with defined grooves surrounding his equally larger omega symbol. The central stripe on his chest has gone from protruding about an inch or two from the rest of Omega's chassis to roughly 5 inches. The jets on his back are now pointed at a lower angle, focusing less on them using them for speed and more on allowing Omega to hover. The flaps on his sides have been given grooves for unknown reasons, the black arrows seen on his waist pipe and flaps have been removed, the red section surrounding his torso is now split into two pieces and he now has sharper and somewhat skeletal hands.

Along with his visual design his physical movements have changed, going from smooth, erratic and human-like to slow and stiff in a more cumbersome manner reminiscent of an old fashioned robot. This is especially exaggerated in cutscenes where movements like turning to face someone, picking up a small object and especially walking take about three times longer or more than a person would be able to. He can run and walk closer to his original speed during actual gameplay, but his movements are still stiffer and he now easily trails behind the likes of Shadow.

Omega's voice was also significantly different from his previous portrayals in Sonic Heroes and Shadow the Hedgehog, sounding much more high-pitched and robotic, relying on echoing filters rather than ring modulation and flanging. 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 only Japanese voice actor so far, also sounded this way in Sonic the Hedgehog despite sounding exactly the same as Jon St. John and Jeff Kramer, Omega's previous English voice actors, in the past two games. Furthermore, Maddie Blaustein later clarified the portrayal change was according to SEGA's direction. Blaustein would later posthumously voice a few select lines of Omega's in Mario & Sonic at the Winter Olympic Games with the rest of his voice lines provided by an uncredited Jeff Kramer, whose lines were recycled from Shadow the Hedgehog. Blaustein's lines in this game were much more accurate to the sound of the voices from the previous English voice actors. This evidence suggests that SEGA decided to change Omega's original voice filters for more robotic ones in Sonic the Hedgehog but later reverted it back to the original, most likely because of poor reception.

Minor changes were made to his visual appearance in Sonic Chronicles: The Dark Brotherhood such as a smaller casing for his "head," flat shoulders with omega symbols on the front and back of both of them, the flaps hanging from his waist pipe are now thicker and rectangular, the arrows on the front of his waist pipe have been replaced with two slots and a richer yellow was used in his color scheme. Proportionally he is similar to his Sonic the Hedgehog design but much closer to his Sonic Heroes look overall.

Starting from Mario & Sonic at the Olympic Winter Games, Omega has mostly returned to his original Sonic Heroes design, with the flattened head, further separated eyes and smoother claws, but has retained the clunkier movements of Sonic the Hedgehog though they are not nearly as slow. The only design differences are that his claws are much more detailed with visible motors between the joints and the width of his upper body has been wider in recent games, save for Sonic Forces.

Omega was given an alternate look in Sonic Runners as part of a Halloween event. His torso is entirely covered by a jack-o'-lantern with Omega's eyes peering through, all the red sections of his body have been recolored purple except for his omega symbol which is now orange, his wrists are now an orange shade and vines extend from the pumpkin to his shoulders and waist.

Omega's silver frontal stripe is also occasionally incorrectly colored as black in some artworks.

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 out there. In Sonic the Hedgehog (2006), he shows depression and anger when Mephiles reveals that Omega is the one who will trap Shadow in the future after the world blamed Shadow for the release of Iblis. 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.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."

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. However, he does not appear to hold them in high regard, referring to them as 'meatbags' in Sonic Chronicles: The Dark Brotherhood.

Omega's only goals in life are to take revenge on Eggman for wasting his potential and destroy the doctor's other robots to prove himself superior. These two goals are absolute above all else in Omega's eyes. As a result, he tends to be extremely headstrong and reckless, unlike his teammates on Team Dark who have more common sense. In Sonic Forces, he performs what is supposed to be a recon mission on Eggman's base, and, rather than sneaking in to get information, storms in guns blazing in an effort to purge the base of every robot within, despite his orders having nothing to do with extermination. 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 prove himself as the greatest of Eggman's robots.

Omega is fairly loyal and dependable when one is 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 and sees them as friends, and trusts their word over everyone else's; such as in Sonic Chronicles: The Dark Brotherhood, when the party discovers him, he tries to attack Eggman the moment he sees him, and Tails' attempt to explain that Eggman is on their side only makes Omega believe that Tails has gone insane and decides to attack him as well, only believing that Eggman is working with them and standing down when Shadow and Rouge confirm this. In addition, he will temporarily abandon his vengeful quest against Eggman (or even indirectly work with him) if he detects a bigger threat, as evidenced by his participation in the battle against Metal Sonic, Solaris, or the Nocturnus Clan.

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 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 rotate his entire upper body the same way during confrontations with Eggman in Shadow the Hedgehog. Whether this is a programming flaw or intentional is not revealed. Also in Sonic the Hedgehog, when Omega is standing still, he makes odd movements as if he's doing warm up exercises.

Weapon arsenal
Omega has a huge array of extremely destructive weapons and machines concealed in his arms which he can switch at will by reconfiguring his forearms or hands to execute a variety of attacks. These include rapid-fire rotary cannons (Omega Machine Gun), flamethrowers (Omega Fire), missile launchers (Omega Missile), fireball launchers (Omega Launcher), multiple semi-automatic single-barreled wrist cannons for firing pellets (Omega Shot) and homing lasers (Lock-On Shot), powerful black miniguns, a double-barreled laser gun that extends from his forearm, a temporal field device, unconventional drill-shaped missiles, and multiple laser beam cannons; a yellow laser that targets a single enemy and a purple laser that covers a much wider area. He can likewise retract his hands into their sockets for scooping up Shadow and Rouge in balls and either use them as melee weapons or launch them as fireballs.

Omega appears to be armed with explosive rounds for his machine guns, as evidenced by the damage he caused to the base he was sealed in by only firing for a few seconds. However, certain weapons of his require the use of magazines as opposed to storing all his ammunition in bulk inside himself. While Omega also appears to possess some form of targeting systems for his arsenal, he tends to be rather inaccurate however, most notably when he fired in every direction when first meeting Shadow with the expectation that some of them would hit.

Physical abilities
Classified as a Power Type, Omega possess considerable amounts of physical strength that easily rivals the likes of Knuckles the Echidna, Big the Cat and Vector the Crocodile as seen in Sonic Heroes, being capable of smashing giant boulders and metal with ease using his bare fists. Omega is also equipped with jet boosters built in his back which he can utilize to help him accelerate along the ground, increase the height of his jumps, hover through midair over long distances, and even move at speeds rivaling Shadow and Rouge. On his feet however, Omega is really slow, though his ground speed can be boosted by approximately 15% with adamantium double-lubricated actuator joints installed.

Being a robot, Omega is equipped with remarkably tough armor which can resist strong blows, certain forms of poisonous gas, psychic manipulation and electrical currents that most of the other characters cannot pass through. Omega also easily survived being in Crisis City while in standby mode for collectively two centuries.

Like most Sonic characters, but unlike most robots, Omega can jump and turn in a ball, known as the Spin Jump  or "Spin Attack"; he can also grind on rails like most characters but unlike most robots.

Omega appears to be waterproof as he does not short circuit when submerged in waters like in Frog Forest, Lost Jungle or Charyb's lair. 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.

Color Powers
By harnessing different variants of Hyper-go-on from Wisps, Omega can use specific Color Powers to transform into a certain form, such as a drill, a laser or even a planet, each one possessing its own unique abilities. So far, Omega has been able to transform into the Cyan Laser, Yellow Drill and Indigo Asteroid. However, these transformations require a steady supply of Hyper-go-on to be maintained.

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 spread-fire 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.

Relationships
Omega rarely shows feelings other than cold hatred, very different from Gamma's calm 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 teammates, Shadow and Rouge, though he didn't care much for them at first.

Shadow the Hedgehog
In the the start of Team Dark's story in Sonic Heroes, after Shadow had woken up from stasis, Omega tried to shoot him, thinking he was one of Eggman's robots. However, Rouge stopped the two and they decided to work together to fight Eggman. Shadow and Omega then became close allies, Rouge even saying that the two are so compatible they, "go together like chili and hot dogs." 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). An example of this camaraderie comes from when Rouge (mistakenly) claims that Shadow is a robot. Omega, despite his relentless goal to eliminate all of Eggman's robots, shows no interest or desire to destroy Shadow. In Shadow the Hedgehog, Omega once again 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 him in this state. Also, in Sonic the Hedgehog, Omega shows anger at Mephiles' hinting of Omega's future betrayal towards Shadow, and proceeds to attack him more heavily. 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 great respect to him, (which is most irregular for Shadow), and shows anger if they 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 kicking 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 life form, but Omega is not a life form and refers to himself with a similar title as the ultimate robot, 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 the Hedgehog (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 is possible that Omega could defeat Shadow like he did in Sonic the Hedgehog (2006), though it is open to debate about whether he did this on his own or whether there were other factors involved, notably Shadow likely holding out on his friend.

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 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 long enough 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 fast friends. Omega even lets her sit on his hand during their victory poses. In Sonic Chronicles: The Dark Brotherhood, she voices her support to Sonic of Shadow joining the team so they can help find a missing Omega, fearing what could happen to him alone when he could be helping them blow up stuff. However, she does show a weariness of Omega's serious and vengeful nature and having to hear him ramble about it constantly. While Rouge definitely trusts Omega, it seems she some times has too much faith in him. During his "infiltration mission" into Eggman's lab, Omega proceeded to go in guns blazing, despite Rouge's protests on the radio and became very worried when Omega called in reporting he had no idea where he was after encountering Infinite. And despite the robots intimidating assortment of weaponry, she's definitely not above teasing him about his grandstanding, and while Omega seems annoyed he does not hold any grudges against her.

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 Sonic, 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 [his] 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, though it is possible he just thought he'd slow them down and not defeat them.

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 afterwards, but he was eventually back in the hands of Dr. Eggman and reprogrammed back into servitude.

It seems his distaste for Metal Sonic is still strong. During the final push against Infinite's replicas, Omega can be seen shooting down a Metal Sonic replica flying by, ignoring closer targets.

Mephiles the Dark
Mephiles was one of Omega's greatest enemies, (possibly coming second to 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 that he was the one responsible for imprisoning Shadow in the future. Enraged by this, Omega proceeded to attack Mephiles with his machine guns. He then revealed this information 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 (but might harbor some form of acknowledgement of Gamma and Beta). It is unknown if he bears any hatred towards them, but it's unlikely, partly because they've all been destroyed.

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 some 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.

His first interactions where when he fought Teams Chaotix and Sonic in Sonic Heroes. Interestingly, Omega seems to have no knowledge of Sonic, simply referring to him, Tails and Knuckles as a group of "Shadow-like creatures."

In Sonic Chronicles: The Dark Brotherhood, after Omega was left in disrepair following an encounter with the Noctunus Clan, Sonic and friends agreed to help Shadow search for him. Whether Shadow is part of the party that finds Omega or not, Tails agrees to repair him in spite of Eggman's protests and makes sure Shadow and Rouge get to check on him via communicator. Omega has two joint POW moves in the game, one with Rouge and the other called "Wrecking Ball" features Big the Cat. Aside from this move, Omega has no other interactions with Big in the game.

Omega would later find himself interacting with Sonic after the blue blue bargained for the lives of Orbot and Cubot. Surprisingly, Omega complied but only in return for physical specification data on Sonic to upgrade himself with.

He also directly interacted with Sonic after to let two Eggman robots walk free in return for data in Sonic Colors.

In Sonic Forces, Omega was rendered non-functional thanks to a battle with Infinite and had been left deactivated in the City for six months. He was found by Tails and the young fox tried his best to repair him but was unsuccessful as the damage was too much. He apologized to the robot's lifeless husk, calling him "buddy," but was prevented from trying further due to the arrival of both a replica of Chaos and Classic Sonic. It is unknown is Tails' repairs had any part in Omega being restored later in the game.

The 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 story lines that involve both Shadow and Rouge, whom both often work apart from Sonic and friends.

However, in Sonic the Hedgehog (2006), Omega was one of the characters grieving over Sonic's death, and he also helped recover the Chaos Emeralds in order to bring Sonic back to life. This shows that Omega may in fact hold Sonic in some form of respect, but he could've also helped recover the Emeralds because Shadow and Rouge were doing so.

Nocturnus Clan
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 didn'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.

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 (it is unknown if this was because he was more concerned with finding Eggman as he indicated 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), actively telling Shadow not to even bother with them.

Some speculate that he is a member of G.U.N. like the rest of Team since Rouge asked them for his location in Sonic the Hedgehog and later asked him to take part in a recon mission for the Intelligence Division, but this has yet to be confirmed.

Infinite
During their first encounter, Omega simply viewed Infinite as someone who stood in the way between him and Eggman and tried to eliminate him as an obstacle. After Infinite nearly destroyed him via the Phantom Ruby's Power, however, Omega developed a grudge against Infinite that was at least as strong as that of Eggman, as his first action upon rebooting himself and joining the Resistance in their climactic fight against the Eggman Empire was declare his intent to exact revenge against Infinite.
