E-Series



The E-Series is a fictional group of robots. They are created by the games' antagonist, Doctor Eggman (or Dr. Robotnik in the early western version) who uses them in his quest to conquer the world.

E-100
Unlike many of Eggman's robots in previous games, the E-100 series that were introduced in Sonic Adventure were important characters in their own right. They were gunner robots, still in the developmental stages. The most prominent was E-102 Gamma, who was a playable character during the game. The names of the E-100 series are Greek letters.

All E-100 robots except ZERO appear on collectable cards in Sonic Rivals.

E-100 Alpha(α) aka ZERO
In Sonic Adventure, ZERO made his debut by chasing a blue Flicky in the possession of a Chaos Emerald that has taken refuge with Amy Rose. ZERO chased Amy around Station Square, at Twinkle Park, the Egg Carrier, Hot Shelter, and finally, the Final Egg base in the Mystic Ruins.

When he went back to the Egg Carrier, he saw Amy and the Flicky with the bird's relatives, who were inside E-101 Beta and E-102 Gamma. ZERO then attacked and knocked out the small Flicky. Amy, who was furious at him and thinking the flicky was dead due to the attack, attacked ZERO and finally destroyed him after smashing his head with her hammer, knocking him into an electric fence that fried his circuits.

Although never referred to as an E-series robot during gameplay, on the Sonic Adventure website accessible via the Dreamcast's internet, he is referred to as E-100 "Alpha" in his character description.

ZERO also seems to make a brief appearance in Sonic Advance 2, chasing you around the pseudo 3D special stage. The manual however, describes him as Dr. Eggman's Guard Robot but he looks exactly the same. If he hits you, you lose 10 rings. In this game, when you complete all special stages with all characters, you unlock Amy.

E-101 Beta (β)
E-101 Beta is a black robot that was created for the E-100 army. He has two guided missile-launchers on his arms. Eggman defined Beta as Gamma's "Big brother", and decided to pit Beta and Gamma against each other to determine which robot would leave the Mystic Ruins base to board the Egg Carrier. Gamma managed to defeat Beta, and Beta was relegated to the storage area to be used as "spare parts." Unhappy with his incompetent design, Eggman sent him to get remodeled into E-101mkII. The parts left over from the remodeling were used as spare parts for other E-series robots.



E-101mkII
Beta was reconstructed into a "Mark II (mkII)" E-100 model – an airborne fighter with improved weapon capabilities, including advanced homing missiles, laser cannon arms, and large spiked gauntlets used for bludgeoning "charge" attacks. Beta mkII navigated with a tail "rudder" and employed an advanced tracking system in his single green "eye". Its improved capabilities included the ability to create a rainbow-colored energy shield, fire a spread of several (ranging from 2 to 10) homing missiles, and fire powerful yellow energy blasts from great distances. It could also knock away hostile projectiles with its arms.

Gamma and the "new" Beta faced off once again aboard the downed Egg Carrier as part of the former's crusade to "rescue" his brothers from Eggman’s control. Beta, despite improvements, was defeated. But he would not go down alone – with what power remained, Beta blasted Gamma at point-blank range, destroying his brother and ironically completing E-102’s mission by freeing the animal trapped within him.

According to an eyecather information card in Sonic X, E-101mkII is 200 cm tall and weighs 1024.256 kg.

E-102 Gamma (γ)
See E-102 Gamma for a more extensive history.



E-102 Gamma is a red robot with a missile launcher arm and a laser targeting device used for aiming. He was the third member of the E-100 series. Oddly, E-102 is the only robot of the E-100 series that did not begin life with a jet pack, though E-102 later picked one up in the Egg Carrier. Gamma was placed in Eggman's E-100 army after proving himself in a fight against his older brother Beta, and he excelled, more so than any of the other E-100 robots, who were sent away by Eggman due to their inferiority. He had a change of heart after meeting Amy and seeing his brother E-101 being deconstructed (though he was actually being rebuilt into E-101 mk II) and the scene in which he is looking in his programing about Dr. Eggman and realize's that he is his enemy, not his master, and decided to free the animals held captive within the remaining robots (this was shortly after being defeated by Sonic and Tails aboard the Egg Carrier, though in his own storyline, E-102 nearly defeated Sonic). Gamma was responsible for terminating E-101, E-103, E-104, and E-105 during the later half of its life. In the process of freeing the Flicky that powered E-101 Beta, Gamma exploded, thus releasing the Flicky within him. These two Flickies just so happened to be the parents of the little bird Amy had been protecting up to that point, thus ending both Amy Rose and Gamma's storylines.

There are robots called E-1000s in some stages of Sonic Adventure 2 who look like Gamma, except that they have two gun arms instead of one and fire low speed bullets. Otherwise Sonic Battle is the only other time the unlikely hero made a return appearance in the Sonic series, except for his role as one of the secret characters in Sonic Shuffle in which the game's description listed him as "revived with the power of dreams".

E-102 Chaos Gamma (γ)
E-102γ Chaos Gamma is the rebuilt version of E-102 Gamma that appears in Sonic Battle. He looks just like his original form, except his gun has been replaced by a hand and the "102" decal on his torso is gone, plus the headlight and light attached to its belt that was on the original Gamma's chest is missing. He can summon various weapons he didn't have before, including drills, electric shock prods which attach to his hands, and a grenade launcher which attaches to his shoulder (the grenade launcher notably appears in his Story Mode pixel art). He serves Eggman, attempting to capture Emerl alongside the E-121s (mentioned below), but in the game's final story, he ceases to be hostile and allows Emerl to train with him for unknown reasons. He is a playable character in Challenge and Battle modes after the player defeats him in Sonic's story.

E-103 Delta (δ)
E-103 Delta is a blue robot with two Missile Launchers on his arms, just like Beta. When Delta was sent away along with E-104 Epsilon and E-105 Zeta, he looked sadly at his brother, E-102 Gamma. At first, Delta was based off Gamma with just one cannon arm, but after being discarded by Eggman, he is based on Beta, meaning he had a pair of Missile Launchers on his arms and a jet booster. Later, Gamma found Delta stranded in Windy Valley. The two brothers battled, and Gamma emerged victorious, then Delta tipped over and exploded. In the original Sonic Adventure, Delta's animal was a green Flicky, but in Sonic Adventure DX, the animal was changed to a parrot.



E-104 Epsilon (ε)
E-104 Epsilon is an orange robot with twin STINGER missile launchers on the arms. Like Delta, Epsilon was first a recolored Gamma, but after he was sent away, he was equipped with a STINGER missile launcher on each arm. After Gamma was proved superior, Epsilon was teleported to an unknown location along with Delta and Zeta. Later, Gamma found Epsilon in a lava-filled cave in Red Mountain on Angel Island. The two fought, and Gamma emerged victorious. The yellow Flicky inside Epsilon managed to escape after Epsilon blew up.



E-105 Zeta (ζ)
E-105 Zeta was initially a purple robot identical to E-102 Gamma in every way (besides color), though it was later altered and reconstructed as a considerably larger stationary defense unit built into the core of the Egg Carrier, equipped with seven advanced missile launchers. Gamma fought and defeated Zeta in the Hot Shelter onboard the Egg Carrier, releasing the trapped animal inside after Zeta's head exploded. A Dreamcast console is included in Zeta's exterior design, inserted by Sonic Team as an Easter Egg. This is in all the Dreamcast, GameCube and PC versions.

In Sonic X, Beta replaced much of Zeta's role, so much that in fact, Zeta only appears on the show in Episode 31, "Revenge of the Robot". This is where Gamma comes to the Hot Shelter to destroy him.

E-121 Phi (φ)
See Emerl for a more extensive history.

E-121 Phis are copies of the robot Emerl used by Eggman. There were 14 Phis which each copied an ability of Sonic and friends. They all were powered by Chaos Emerald shards and because of this Emerl destroyed them in order to get all the Emeralds.

E-123 Omega (Ω)
''See E-123 Omega.



E-123 Omega was the last robot of the E-100 series, deactivated when Eggman began work on his E-1000s. It's the only playable robot in Sonic Heroes. After being reactivated by Rouge the Bat, he swears vengeance on Eggman for shutting him down. Omega is seen again in Shadow the Hedgehog where he and Shadow the Hedgehog infiltrate Eggman's base towards the end of the neutral story. He is also playable in Shadow the Hedgehog (in the GameCube version) using a second controller in the middle levels of the story mode. He is only a bit over four feet, several feet shorter than Gamma. Although he looks like E-102 Gamma, he possesses stronger and more numerous amounts of weaponry, as his intentions aren't anywhere near as noble. His latest appearance is in the 2006 Sonic the Hedgehog game.



Isaac
While not technically a member of the E-100 Series, Isaac is a robot from the Sonic the Hedgehog comic series, and his design is simply a golden recolor of E-102 Gamma. He was created in the distant past by Professor Niven Clarke and was subservient to Dr. Ivan Kintobor. Activated when the Xorda aliens launched their first assault on Earth/Mobius, he monitored Kintobor while he was in stasis in his bunker.

Rediscovered by Shadow and Metal Sonic in the present day, he recounted his experiences of observing history from afar, including the first conquest of Mammoth Mogul and the coronation of the first king of the House of Acorn. Isaac is shown to maintain a nuclear launch silo beneath the bunker, and still tends to the dormant body of Ivan Kintobor. By unknown means, data was stolen from him by Dark Legion scientist Dr. Finitevus.

It is possible there is a link between Isaac and the SWATbot identified as Isaac by Ian Droid in Sonic Super Special #7, but it is untrue that Robotnik stole Isaac's design and used it for his E-Series.

E-1000
The game Sonic Adventure 2 and its remake Sonic Adventure 2: Battle presented the E-1000. The E-1000 was a mass-produced variant of E-102 Gamma that served as a normal Badnik-style enemy, sporting a pair of cannon arms. Despite being paired for what may seem like double the firepower, the E-1000 line's weaponry, with low-velocity projectiles, and no homing feature, was generally far less effective than E-102's single missile launcher.

E-2000
Two more E-models appeared in the game Sonic Heroes, though by that time, Doctor Eggman had progressed to the E-2000 series of robots, namely the E-2000 itself. The E-2000 is a red humanoid robot armed with a powerful energy cannon and a shield, along with the ability to transform into a plane-like shape. The game also featured the E-2000R, a gold-colored variant of the regular E-2000 with extra armor.

E-10000


Sonic Riders featured yet another branch of the E-Series. This time, the E-10000 series. A difference in this branch is that they are referred to by color, as opposed to by name and number. 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-102 Gamma.

E-10000R
E-10000R (called Robo 1 on the official American website) is a red robot built for speed, and according to the official Japanese Sonic Riders website, is equipped with the same kind of engine as Metal Sonic. In Story Mode, the E-10000R walks into a battle between Knuckles the Echidna and Storm the Albatross, and gets severely damaged. It later tried to capture the heroes with visible damage from the battle, meaning it is the same robot.

E-10000R has the ability to split its head from its body to scare or strike opponents or simply attack them with its large fists. E-10000R's unique Extreme Gear is called the E-GearR, and it can be unlocked as a playable character for playing 50 hours.

E-10000G
E-10000G (called Robo 2 on the official American website) is very similar to his "brother", except it is green and seems to be massproduced. E-10000G is a power type character in the game. However, when met as opponents in Story Mode, E-10000G has the powers of speed, flight, and power characters. In Story Mode, E-10000G robots will fill the spots not used by other characters, since Dr. Eggman is the creator of the race.

E-10000G is equipped with a large light in its body that it can use to blind opponents, and also punches enemies with its fists. E-10000G's unique Extreme Gear is called the E-GearG, and it is unlocked as a playable character by playing for 20 hours.

E-10000Y
E-10000Y is an enemy robot seen in the Egg Factory level. It can not be played as, and is instead used as an obstacle. E-10000Y is small, yellow and floats just above the ground as it has no legs. Its main purpose appears to try and capture intruders in Eggman's base. When playing Egg Factory's frozen version, Ice Factory, the robots are instead used to spray ice around the factory, and are still obstacles.

Type Errors
On the American Sonic Riders website, E-10000G and E-10000R accidentally got their stats (or possibly bios) reversed, and the website claimed that G was speed and R was power (it also lists their names as "Robo 1" and "Robo 2"). The Japanese website was correct, but in E-10000G's bio, it said the name "E-10000R" instead and vice versa. When the game came out, G turned out to be power and R was speed.

Sonic X (E-1)
Several robots from the E-Series appeared only in Sonic X. These robots are not canon to the games, and given differences between the Sonic X continuity and the game continuity, there may be some conflict between numbers. The robots are as follows:
 * E-11 Beacon - Episodes 4 & 12. Beacon is a purple bird robot, which Eggman first activated to help him retrieve a Chaos Emerald, but it is destroyed by Sonic. Eggman later activates a second Beacon model to help ward off an attack by G.U.N.'s air force.
 * E-12 Behemoth - Episodes 1, 11, 12, & 28. Giant massproduced humanoid robot that protects Eggman's base. Sonic destroys several of them before finding Eggman. One of the few reoccuring robots from the series.
 * E-13 Guardbot - Episode 1, 11-13. Basically a machine gun turret on tank treads. One of these robots break Eggman's Chaos Emerald device, and is as such the reason why everyone is sent to Earth.
 * E-14 Sneezer - Episodes 1, 11, and 12. A missle-launching robot that protects Dr. Eggman's headquarters. Two boxy launchers make up it's 'arms', while an extra trio of missles adorn it's head.
 * E-18 Guerra-Hard - Episode 13. A super powered combat robot, Guerra-Hard is powered by two Chaos Emeralds. Sonic is forced to battle the robot when he breaks into Eggman's base. Luckily, he is able to defeat it and capture the Chaos Emeralds inside. It bears a striking resemblance to the Super Robot Mazinger Z. Guerra-Hard is 27 meters tall and weighs 550 tons.
 * E-21 Ballios - Episode 10. A team of athletic robots built for playing baseball. They challenge Sonic and co. to a game, the winner of which gets a Chaos Emerald. They are beaten and destroyed. A Ballios is 120 cm tall and weighs 120 kg.
 * E-23 Missile Wrist - Episode 3. Missile Wrist is equipped with missile-like grappling hooks attached to retractable cords in place of its hands. To start his campaign to take over Earth, Eggman unleashes Missile Wrist to cause havoc in Station Square, only for it to be destroyed by Sonic.
 * E-35 Funfun - Episode 12. A giant yellow bird robot with an equally giant fan that is used to stop Sonic and his friends from getting a Chaos Emerald. It is powerful enough to blow away the X-Tornado, but is destroyed regardless. Funfun was 9 meters tall and weighed 3 tons.
 * E-38 Octoron - Episode 9. An octopus robot that Eggman uses in order to try to drown Sonic. It fails and is destroyed..
 * E-39 Quizon - Episode 9. An army of construsction robots with four arms with various tools. Eggman uses them to build a theme park in his image, and when Sonic arrives they combine into a long snake-like robot that is destroyed by Amy. A Quizon is one meter tall and weighs 150 kg.
 * E-40 Egg Fortress - Sonic X Episodes 15-20, 47. Following the subsequent destruction of his original headquarters, Dr. Eggman reappeared from under the wreakage with a new mobile air fortress. Purple in color, the ship was designed with a trio of massive drills, one on the prow and two on the wings. A retractable bridge and three gigantic rocket engines added to this ships apearance. Armed with a battery of flak cannons and missle launchers, the Egg Fort also carries a pair of high-powered Egg Blasters, which in it's initial usage nearly destroyed the X-Tornado outright. After numerous defeats and repair work, Eggman retired the Egg Fort in Episode 20 in favor of the Egg Fort 2. The Egg Fort was ressurrected in Episode 47, having been commandeered by GUN forces into a airship of their own to combat Eggman's new Egg Battleship. It is uncertain what happened to the craft after the assault on the equator.
 * E-42 Torole - Episode 15. A bipedal walker robot armed with a wrecking ball. It was destroyed by the heroes. Torole was 12 meters tall and weighed 40 tons.
 * E-43 Falcon - Episode 15. Massproduced orange bird robot. Several chase Sonic, but he hops on and rides one to the Egg Fort.
 * E-45 Sumo-man - Episode 21. Eggman sends Sumo-man, an extremely strong, but unintlligent robot, to stop Sonic from winning a race with Sam Speed. Too big and slow to catch Sonic, Sumo-man takes it out on himself, hitting himself in the face. Underestimating his own strength, Sumo-man is sent flying and crashes into Eggman's base. Sumo-man was 12 meters tall and weighed 30 tons.
 * E-47 Pumpty - Episode 5. Not to be confused with Humpty, a robot from AoStH and Dr. Robotnik's Mean Bean Machine.
 * E-51 Intelligente (US)/Teacher Robot (Japan) - Episode 6. Intelligente is a robot teacher designed to interact with kids, and Eggman intended for him to brainwash the children into liking him. However, Intelligente became loved himself, and did not want to serve Eggman. He was forced into it again, He attacked Sonic with his "homework attack" (a missile launcher hidden under his hat) but sonic dodged all his missiles and destroyed him.
 * E-57 Clurken - Episode 16. A jellyfish robot sent to stop Sonic from acquiring an underwater Chaos Emerald. It was destroyed. Clurken was 27 meters tall and weighed 12 tons.
 * E-65 Gorru-Gaooh - Episode 18. A gorilla robot piloted by Decoe and Bocoe. It uses camouflage technology that renders it invisible, but Sonic destroys it regardless. Gorru-Gaooh was 8 meters tall and weighed 10 tons.
 * E-66 Da-Dai-Oh - Episode 22. A gigantic robot that Eggman brings with him during his vacation. It looks like a large metallic dome with legs, arms, and a head where Eggman is seated. It had extendable arms and spiked balls for hands, but was destroyed when it slipped on some unsteady ground. It was 100 meters tall and weighed 1000 tons.
 * E-70 Noizi - Episode 11. A robot equipped with super powerful sound wave generators, Noizi was set to guard Eggman's fortress. He nearly defeated Topaz and Rouge, but was bested when Rouge threw a bomb into its main speaker and set it off. Noizi was 8,2 meters tall and weighed 2,5 tons.
 * E-74 Weazo - Episode 23. A large green weasel-like robot equipped with a flamethrower, Weazo comes along to help Eggman retrieve the purple Chaos Emerald. However, despite its power, it is beaten by a tag-team effort from Sonic and Knuckles. Weazo was 7 meters tall and weighed 14 tons.
 * E-77 Lucky - Episode 25. Designed to be the ultimate lucky charm, Lucky's ridiculous and clumsy body is covered in good luck charm symbols. Lucky was dispatched to locate the seventh Chaos Emerald, but wasn't doing a good job because it kept falling over. Eventually, Lucky found it, and was going to give it to Sonic. Caught in a battle between Eggman and G.U.N., Lucky turned out to live up to his name, constantly dodging attacks that should have destroyed him. He also has the ability to fly. Lucky later appeared in a fighting tournament, and made it to the semi-finals because for certain reasons, such as his opponents never showing up or were forced to leave before fighting began. Unfortunately, his luck ran out when he had to face Emerl, as his victory dance burned out the remaining energy in his power cells and subsequently shut-down. Lucky was one meter tall and weighed 100 kg.
 * E-88 Lightning Bird - Episode 24. An ostrich-like robot. Sonic destroys a few and gets a part of one stuck in his ear. A Lightning Bird was 13 meters tall and weighs 25 tons.
 * E-90 Super Sweeper - Episode 5. A giant spacecraft, Eggman dispatched it to suck up satellites to grind into robot parts. Equipped with powerful missiles and lasers, a powerful suction force, and the ability to fly higher and faster than Tails' Tornado, Sweeper was seemingly unbeatable. However, it was no match for the improved X Tornado, and was destroyed by Sonic. It looks remarkably similar to the airplane Thunderbird 2 from Thunderbirds.
 * E-91 Lady Ninja / Ku-no-ichi (Japan) - Episode 17. A robot based off of a female ninja, E-91 was equipped with shurikens, gliders, an electrocution net, a chain with a weight at the end that could either be small or turn into a wrecking ball, and an entire arsenal of different Ninjutsu techniques. Her name is a pun; the word "Kunoichi" means "Lady Ninja", but when the word is separated, it also means "91" (Ku-no-ichi). The Lady Ninja was dispatched to retrieve the red Chaos Emerald, but ran into trouble in the form of Knuckles the Echidna and Rouge the Bat. Eventually, she had Knuckles on the ropes, but Knuckles' human friend Hawk dumped water over her. Taking advantage, Knuckles hit her with a super punch, destroying her. Lady Ninja was 120 cm tall and weighed 200 kg.
 * E-99 Eggsterminator (US)/Egg Emperor (Japan) - Episode 26. The robot form of the Egg Fort II, the Eggsterminator was unleashed by Eggman when he was facing both Sonic and G.U.N.'s Beetle robots. Powered by six Chaos Emeralds, Eggsterminator could move faster and attack stronger than Sonic. Unfortunately, all the power sent him out of control, causing him to attack Sonic and co. without hesitation and glow an orange color. However, Eggsterminator was destroyed when Super Sonic, charged up with the energy of all seven Chaos Emeralds, rammed through it multiple times. The Eggsterminator was named "Egg Emperor" in Japan, and the name may have been changed to avoid confusing it with the "Egg Emperor" from Sonic Heroes.
 * E-3000 Egg Mars - Episode 56. A large robot that Eggman deploys in battle against a frog-like Metarex and in his efforts to acquire a Chaos Emerald. It was destroyed by the Metarex.
 * Others - When Eggman chooses robots with cards upon placing them into a random-selecting slot machine (the selected robot appears on the 3 reels), several robots (or parts of them) can be seen that was never used.
