The E-Series (E-シリーズ Ī Shirīzu?) are a group that appears in the Sonic the Hedgehog series. They are a production line of robots created by Dr. Eggman, who uses them in his quest to conquer the world. They are considered to be elite versions of the Badnik robots Eggman used in earlier games. The name was first used in Sonic Adventure.

The most famous E-Series robots are the E-100 Series from Sonic Adventure, particularly E-102 Gamma (who was a playable character in that game) and E-123 Omega (who has been a recurring character since his introduction in Sonic Heroes)

List of E-Series Robots

E-100 series

The E-100 Series (E-100シリーズ Ī Ichi-Zero-Zero Shirīzu?) are the most prominent E-Series robots in the Sonic the Hedgehog series, being the only ones whose E-Series designations were revealed in-game. They were introduced in Sonic Adventure, in which they were prototype gunner robots, meaning that almost all were equipped with some sort of lock-on target ammunition, though its utility varied between models, but the following robots have since then evolved into more versatile machines in terms of combat. The E-100 series were also given Greek letter names.

Unlike many of Eggman's robots, some of the E-100 series were important characters in their own right. The E-100 Series is known for being more uniquely designed machines rather than Eggman's mass-produced, being more humanoid, more armed, more intelligent, and overall far more dangerous than their predecessors. Due to having so many capabilities and high intelligence, some robots from the E-100 Series have been known to go rogue.

The most prominent robots in the E-100 series are E-102 Gamma and E-123 Omega. Both of these robots are well known for eventually gaining independence and breaking free from Eggman's control, however for vastly different reasons. After the creation of E-123 Omega, Eggman has seemingly decommissioned the E-100 series.

Allusions to other E-100 Series units are made throughout the series. In Sonic Battle, partially built green and red E-100 Series robots can be seen in the Gimme Shelter. In Sonic Chronicles: The Dark Brotherhood the Rusty Hydraulics that E-123 Omega can use are said to be leftover parts from disassembled E-100 Series robots, but it is never specified which units.

E-1000 series

  • E-1000 - mass-produced robots that resemble E-102 Gamma, but with two gun arms.

E-2000 series

The E-2000 Series appears in Sonic Heroes. There are two models in this series, which are both highly powerful and destructive machines:

E-10000 series

Sonic Riders and Sonic Free Riders featured yet another branch of the E-Series. A difference in this branch is that they are referred to by color, as opposed to by name and number and is rather more programmed for Extreme Gear racing than direct combat. The E-10000 robots appear to be similar in appearance to Eggman, but more advanced. Except for color, they both seem to have the same, basic structure. They are also equipped with a targeting and analyzing mode, similar to what is displayed by E-101 Beta, E-102 Gamma, E-103 Delta, E-104 Epsilon and E-105 Zeta. Several of these robots can also be raced against in the Relay Races of Sonic Free Riders.

Also, unnamed yellow, purple, and orange robots that resemble the E-10000 series can be found throughout the Egg Factory and Ice Factory stages in Sonic Riders.

In other media


Sonic X

Main article: E-Series (Sonic X)

In the anime series, Sonic X, the E-Series make up Dr. Eggman's standard robot forces. In this media, the E-Series include not only the first members of the E-100 Series from the games, but also several other models exclusive to this media.

Books and comics

Archie Comics

In the Archie Comics' Sonic the Hedgehog, following Dr. Eggman's takeover of Dr. Ivo Robotnik's global empire, the doctor slowly replaced his late counterpart's conventional SWATbot forces with his newly designed E-Series robots. After Enerjak's attack on New Megaopolis and E-102 Gamma's series of attacks on the elite members of the E-Series, however, the number of Dr. Eggman's E-Series robots were greatly diminished. However, following the Super Genesis Wave, many of the E-100s have come back into existence.

IDW Publishing

E-107 Theta of the E-100 Series, from Sonic the Hedgehog #8.

In the Sonic the Hedgehog comics series and spin-offs published by IDW Publishing, the E-100 Series is a series of robots created by Dr. Eggman. Its history is virtually identical to its game counterpart's, up until after the events of Sonic Forces. In this media, it consists of unique robots that are no longer produced by the Eggman's Empire. However, parts of them are collected by some collectors and traders.


  • The code names for the units in the E-100 Series all come from characters in the Greek alphabet.
  • The Archie Comics series features a robot named Isaac who resembles a gold-plated E-102 Gamma.
  • In the prototype images of the Sonic Adventure, the E-100 Series seem to have all the same color as Gamma.[1]
  • In Sonic Adventure and Sonic Adventure DX: Director's Cut, all the E-100 Series robots apart from ZERO are powered by a type of bird.
    • E-101 Beta is powered by a cream bird.
    • E-102 Gamma is powered by a pink bird.
    • E-103 Delta is powered by a parrot.
    • E-104 Epsilon is powered by a robin.
    • E-105 Zeta is powered by a peacock.
  • The American Sonic Riders website accidentally listed E-10000G as a Power Type and E-10000R as a Speed Type and only named them as Robo 1 and Robo 2 respectively. Similarly, the Japanese website incorrectly named E-10000G as E-10000R.

"E-113" and "E-117" in LEGO Dimensions.

  • Two non-canonical E-100 robots, whose names are "E-113" and "E-117", make an appearance in LEGO Dimensions as part of a puzzle in the level "Sonic Dimensions". They get tricked into destroying each other after one accuses the other of dropping an Eggman Mark on its head.
  • 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.
