First Seen: Sonic Heroes (2003)
E-123 Ω, commonly referred to as Omega, is a renegade E-Series robot first introduced in Sonic Heroes. The last of Dr. Robotnik's discontinued E-100 Series, Omega was consigned to storage by the Doctor for the express purpose of preventing Shadow the Hedgehog's release from captivity. However, Omega harbours a deep resentment towards his creator for sealing him inside an obscure facility, and has not only completely rejected his initial mission, but seeks to take revenge in the way one might expect for a combat droid: destroying all Eggman's robots and the Eggman himself.
Built as an armed and dangerous killing machine of the Eggman Empire, Omega usually plays the stereotypical emotionless robot. Unlike his predecessor E-102 γ, Omega's betrayal of Robotnik stems not from any discovered sense of mercy and compassion, but rather a far less noble anger at Eggman for being locked away in seclusion rather than being let out to run riot and shoot people.
The Sonic Chronicles: The Dark Brotherhood Codex does state that Omega at least has the capacity (if rarely used) for less wrathful machine emotions, when directed towards Shadow or Rouge:
|“||Omega can be harsh and ruthless, but he does have free will, something that Eggman's robots tend to lack. While he rarely shows emotion beyond hatred and desire for revenge, Omega is capable of feeling loyalty and friendship, as he considered his Team Dark teammates to be friends. Whenever he teams up with Sonic, it's not because he likes Sonic, but because Shadow is part of the team.||„|

Although his chief targets are Eggman's robots, Omega has little sufferance for biologicals beyond his Team Dark comrades, referring to Sonic's team pejoratively as "meatbags", and having to be rapidly talked out of shooting Tails by Shadow even as the fox is trying to repair him.
Omega is first seen in the Sonic Heroes introduction cutscene for Team Dark. Rouge the Bat, searching for "Eggman's secret treasure", breaks into the room where both E-123 and Shadow the Hedgehog are being stored in suspended animation. The thief's presence alone reactivates the bot, who boots up all guns blazing. After a brief fight between Omega and the also recently awakened Shadow, Rouge intervenes and manages to convince the combatants that all three of them want the same thing: to get to Robotnik. Thus it is in the sparking ruins of the Eggman storage facility that Team Dark is formed.
The robot spends the game pursuing Neo Metal Sonic's fake Eggmans with his new comrades. After helping to distract Metal Madness, the end sequence shows Omega cradling the defeated Metal Sonic with Shadow.
Omega's gameplay in Heroes is as a Power type. As such, his moves are similar to other power types in that he has melee attacks as well as the ability to break obstacles and use the Triangle Dive. Omega's attacks focus on the large amount of concealed weapons in his forearms.
While in the air, Omega can retract his arms, and launch his spinning teammates as fireballs via Fire Launcher. On the ground, his Circular Attack is the Omega Arm, where he can fire either a stream of bullets, a flame thrower, or explosive drills, depending on his Power Core count. In addition, as part of the Team Blast attack Chaos Inferno, Omega can fire a large sweeping laser (similar to the E-2000's) that destroys all enemies in range, and takes 30 HP off any boss.
It is said by many sonic fans, and even some Sega officials, that Omega is a remake of E-102 Gamma. The body color and the structure is the same, and after Eggman discovered Gamma on the Egg Carrier, he rebuilt him. However, when he regained his memory, Omega turned against Eggman and was locked up, later to be found by Rouge.
Appearing as one of the partner characters in Shadow the Hedgehog, Omega is found fighting with the human Guardian Units of Nations troops during their assault on Eggman's volcano stronghold in both Iron Jungle and Lava Shelter. In the Lava Shelter endings after defeating the Egg Breaker, Shadow and Omega terminate Eggman, intending to usurp the Eggman Empire and turn it into an android hegemony.
Like all partner characters, he can be controlled by a second player, though his move set is limited to the melee attack and Homing Attack. In this game, Omega's claws are black instead of silver.
Omega does not appear in Sonic Battle, but he is briefly mentioned by Rouge on encountering Chaos Gamma at the foot of Holy Summit. The bat notes that Chaos Gamma looks vaguely similar to Omega; Chaos Gamma was implied to be a robot incorporating parts from the earlier E-102 γ.
Chronologically, Omega first appears in Sonic '06 when Rouge seeks him out in Tropical Jungle. In quite a clever piece of paradox exploitation, Rouge gives Omega a Chaos Emerald to deliver to Shadow in Crisis City - over 200 years in the future. The bat knows her plan will likely succeed because she saw Omega there, in standby mode, when Mephiles timeshifted her and Shadow past the Day of Disaster.
Although Omega is indeed successful at delivering the Emerald to Shadow, allowing him to use Chaos Control during the battle against Mephiles Phase 1, it seems that Omega's intervening two centuries were not all spent in low-power mode. Later in Wave Ocean the robot confesses that he was responsible for capturing and imprisoning the alternate-future version of Shadow presented by Mephiles in Flame Core.
Nonetheless, all these events (as with the bulk of the game's plot) are erased from history after the defeat of Solaris at the End of the World. In this level Omega helps effect the resurrection of Sonic by retrieving a Chaos Emerald from the Flame Core fragment.
In Sonic '06 Omega saw his first (and to date only) solo gameplay in sections of Shadow's levels. Play style is similar to that of E-102 in Sonic Adventure, as he has lock on attacks, and the ability to hover. He is playable in a considerable amount of stages, and is one of the three characters featured in the downloadable "Team Attack Amigo" missions.
Along with Cream, Omega is one of two non-mandatory characters in Sonic Chronicles: The Dark Brotherhood. He is introduced to the game via Shadow, who is searching for his friend after the machine entered the ruins of Eggman's Metropolis to defeat any remaining Eggman mechs. E-123 was overpowered and partially dismantled by Nocturnus-controlled Eggman machines, a fate which he describes as "EMBARRASSING". Tails repairs Omega at Shadow's insistence (and despite Eggman's protests), and the robot goes on to become a playable member of the party.
