E-100 Series (Archie)

The E-100 Series, sometimes known as the E-100 Droids, are a group that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They are a group of advanced robots created by Dr. Ivo "Eggman" Robotnik. They are personal enforcers for the Eggman Empire, created during Eggman's campaign to harness the power of Chaos. They exist in both the Pre- and Post-Super Genesis Wave timelines.

Creation
Dr. Eggman had created the E-100 Series in the year 3235, but were hardly used prior to being destroyed, however. Four of the E-100 Series robots–E-101 Beta, E-102 Gamma, E-103 Delta, and E-104 Epsilon–were assigned to a competition to search and capture the entity that absorbed Chaos' tail, that being Froggy. Later, E-102 Gamma had found Froggy in the Mysterious Cat Country with Big the Cat. Gamma was successful on capturing Froggy, and, along with Beta, Delta, and Epsilon, returned to the Egg Carrier to win the competition. Eggman was pleased at Gamma's competence on the assignment, claiming Gamma as the winner. Sometime during this, a group of E-100 Alpha were sent to track down a green Flicky, to which had escaped at the Station Square. Amy Rose was caught in the crossfire, as she was protecting the Flicky. However, she was captured by the E-100 Alpha robots, but the Flicky followed, realizing Amy's actions were to protect the bird.

However, Gamma realized the eventual fate of Amy and the Flicky if he were to follow Eggman's orders, thus he decided to free the two from the Egg Carrier prison. Later, both Sonic the Hedgehog and Miles "Tails" Prower arrived at the Egg Carrier, which led to Eggman ordering Gamma to attack the two Mobians. With Sonic tricking Gamma to shoot himself, Amy stopped the fight between the heroes and Gamma, as she explains that Gamma saved her from near roboticization. Sonic believes in Amy, and as the heroes prepare for the final fight, Gamma leaves the Egg Carrier, saying good bye to the friend he saved.

Downfall
A new series known as the E-1000 Series would be built and stationed at Prison Island. Eventually, Eggman would build the E-105 Series to invade Feral Forest, but all of the robots were easily destroyed by Sonic, Sally Acorn, Geoffrey St. John, and Hershey the Cat. Similar robots, possibly E-100 Series, were also assigned in the Operation: Triple Threat battle plan, but were ultimately destroyed by the Chaotix, Amy Rose, Rouge the Bat, and General Armand D'Coolette with his Mes Braves Battalion.

Gamma had set out his goal to eliminate all E-100 Series robots, and was successfully at wiping out all of his brothers with the exception of himself and the then-inactive E-123 Omega. Believing Gamma was a huge threat, Eggman sent Omega to obliterate the traitor, to which Omega successfully accomplished. However, Gamma had uploaded his free will into Omega, causing Omega to change his motives and join the Guardian Units of Nations organization, later becoming a prominent member of Team Dark.

Revived With New Assignments
Much about the origins of the E-100 Series in the Post-Super Genesis Wave timeline is fairly unknown, but it is known that E-100 Alpha ambushed Amy Rose and a Flicky, and that Sonic had faced Gamma at the Egg Carrier. E-123 Omega, also, had went through his betrayal sometime during the timeline, as he currently resides with Team Dark. Currently, E-106 Eta is a Badnik Horde Commander nearby Spagonia, and E-113 Xi was stationed at the Rocky Jungle Zone under the care of the Soumerca Egg Army, until it was shut offline by Mighty the Armadillo.
