The E-Series[1] (Eシリーズ[2] Ī-Shirīzu?) is a group that appears in the Sonic the Hedgehog series. It is a line of Badniks created by Dr. Eggman. Following their appearance during the Chaos incident, the E-Series has become the most produced line of Badniks.[1][2] Forming some of the doctor's greatest creations, they are very advanced robots developed to advance weaponry.[1]


There is not a general description for all E-Series models, as their appearance and features have varied over time. What all of them do share, however, is a humanoid appearance, typically based off of another individual such as Dr. Eggman. Another very common characteristic of theirs is that their names always start with the prefix "E-".

Compared with other Badniks, the E-Series robots are very advanced.[1] Most of them have also shown extreme resilience to damage, being able to withstand the force of powerful attacks like the Spin Attack. Having been developed with the purpose of advancing weaponry as well, many bristle with their own arsenals of weapons that include cannons and laser blasters.

Compared to most Badniks, most E-Series models posses little to no noteworthy personalities, although they are capable of communication with each other or others. Additionally, some of these robots were capable of abandoning the Eggman Empire entirely and pursuing their own independent goals afterwards.

Sonic X[]

Main article: E-Series (Sonic X)

In the Sonic X anime series and its comic series published by Archie Comics, the E-Series were Dr. Eggman's standard robot forces.

Books and comics[]

IDW Publishing[]

Sometime after E-123 Omega was created, the robot defected from the Eggman Empire and began opposing Dr. Eggman and everything he created.[3][4]

About a month after the Eggman War, E-106 Eta roamed one of Eggman's bases by itself. It did not notice Espio the Chameleon, who was investigating the base, sneak past it.[5]

The Fate of Dr. Eggman[]

Stationed inside the computer room in one of Eggman's pyramid bases, E-107 Theta and its horde of Spinas encountered Sonic the Hedgehog, Silver the Hedgehog and Whisper the Wolf when they broke into their room. While Theta attacked the intruders, it was protected by the Spinas who kept the heroes occupied. However, When Whisper shot Theta with her Variable Wispon, it retaliated swiftly. Before Theta could kill Whisper, Silver blocked its missiles. Sonic then moved in and attacked Theta with a swift assault, destroying it and releasing the Picky that powered it.[6]

Crisis City[]

Omega fighting Zombots, from Sonic the Hedgehog #19.

E-123 Omega soon after assisted Team Dark in evacuating Sunset City by stalling the local Zombots.[4] During the evacuation however, Omega was destroyed. Fortunately, Tails managed to save his head and take him to Restoration HQ.[7]

All or Nothing[]

Omega's head was later moved to Angel Island after Restoration HQ was invaded by Zombots.[8]

Out of the Blue[]

Following the conclusion of the Zombot apocalypse, Orbot and Cubot found Omega's head in a Rescue Shuttle that Dr. Eggman stole from Angel Island.[3] After getting to safety, Dr. Eggman reconnected Omega's head to a rebuilt body, which he kept immobilized, thus keeping Omega from moving his new body. He then connected Omega to the Giga Omega mecha, which he used to attack Spiral Hill Village.[9] Fortunately, Omega was freed by Sonic, and a vengeful Omega destroyed Eggman's mecha. However, he fell apart shortly after.[10]

Chao Races and Badnik Bases[]

Omega being repaired, from Sonic the Hedgehog #36.

With Omega still broken and in need of repairs, Tails was assigned to repair him. However, he needed spare parts from the E-100 Series and ciphers for Omega's blueprints from Eggman's base. Amy and Rouge thus went to get parts from the famous collector Clutch at White Park Grand Chateau while Sonic and Tails went on to get the ciphers from an abandoned Eggman base, where they encountered Egg Keepers. Rouge also took Omega's head with her, which she left in Clutch's apartment to carry out a secret plan.[11] Shadow later found Omega's head, who explained Rouge's plan to him. After stunning Clutch, Shadow left Rouge, Amy, and Cream behind with Omega.[12] When Dr. Starline later kidnapped Rouge and Tails, Omega, at the behest of Rouge, scared Starline with a loud sound, in order to make him drop his guard. Later, back at Tails' Workshop, Omega was rebuilt with the aid of Belle the Tinkerer using his blueprints and the spare parts.[13]

Imposter Syndrome and Trial by Fire[]

The E-200 schematics were destroyed during the battle of Eggperial City.[14]

Scrapnik Island[]
Urban Warfare[]


  • In Sonic Adventure: Navigation Guide, ZERO is referred to as the prototype of the "Eggrobo E-Series" (エッグロボEシリーズ[15] Eggurobo E-Shirīzu?) in its profile. This hints that the E-Series, or at least the earliest models, derive from the Eggrobos. However, the validity of this is unconfirmed.
  • There is a large machine in Death Chamber in Sonic Adventure 2 with an "E-01" decal on it. It is unknown if it is technically one of the E-Series robots, although it could be the base's central control computer.
