E-series

---

In the Sonic the Hedgehog series, Doctor Eggman (or Dr. Robotnik in the early western version) created many robots entitled his E-Series. The name gained prominence after the release of the video game Sonic Adventure, replacing the term badnik, which had been used to describe Eggman's robots previously in most continuities. Presumably, the "E" stands for "Eggman" or "Egg", though this is not known for certain.

E-100 Series

Unlike many of Eggman's robots in Sonic Adventure or previous games, the E-100 series 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.

\"E-100 Alpha (α)\" Zero

Note: Sega does not say that Zero is an E-series robot. In the game, he is referred to as just 'Zero'. He could, however, be considered by Eggman as the unmentionable first prototype to the E-100's.
Zero is a giant green and black robot with red eyes that many people say resembles a trash can with large arms and wheels. It played a major role in Amy's scenario of the video game Sonic Adventure, and makes a cameo appearance in Sonic Advance 2 as an obstacle in the special stages. 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 parents, 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, attacked Zero and finally destroyed him after smashing his head with her hammer, knocking him into an electric fence that fried his circuits.

Zero's attacks included firing shockwaves and swinging his arms. Though often cited as 'E-100', Zero has never been confirmed as part of the E-100 series, and his status as E-100 is fan conjecture. Some fans have said he is E-0 since his name is "Zero". He is typically thought of this because there are a few "E" designs placed on his head, although these could be merely labels given due to his creator, Eggman. In the games, he is known only as "Zero the Chasemaster" and is given no backstory. It is theorized however that he is a prototype for the later E-series models since he does not have an animal inside.

Isaac

Isaac is a robot from the Archie Comics series. He is a golden recolor of E-102 Gamma, and was created by Ivan Kintobor. He came to life when the Xorda attacked Earth/Mobius, and monitored Ivan while he was in stasis. He continued to exist up to the present day, thus learning much about Mobius' history that no one else knew. He was found by Shadow the Hedgehog, and teamed up with him in a battle against Sonic and Metal Sonic. It is possible there is a link with the SWATbot identified as Isaac by Ian Droid in SSS#7 but it is a myth that Robotnik stole the design for robots E-101 - E-106.

E-101 Beta (β)

E-101 Beta is a black robot that was created for the E-100 army. He has two homing missile-launchers for arms. Eggman defined Beta as Gamma's "older 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 the sleek Beta MkII, which has one eye, huge claws, and hovers constantly. Its improved capabilities include the ability to shield itself, fire a spread of several (ranging from 2 to 10) homing missiles, and conjure rainbow-colored balls of energy, which can be thrown from great distances. E-101 mkII was Gamma's final boss. The parts left over from the remodeling were used as spare parts for other E-series robots.

E-101 Beta (β) MK2

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".

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.

E-102 Gamma (γ)

E-102 Gamma is a red robot with a missile launcher arm and a laser targeting device used for aiming. He was the second or third member of the E-100 series (depending on whether or not ZERO is in fact E-100 Alpha). 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 soldiers. He had a change of heart after meeting Amy, 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 instaed of one and shot 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. The headlight that was on the original Gamma's chest is missing as well. He has various weapons hidden in his chest that the original didn't, including drills and electric shock prods, which attach to his hands, and a grenade launcher, which attaches to his shoulder, much like Omega. He serves Eggman, attempting to capture Emerl alongside the Phis, but in the game's final story, he ceases to be hostile and allows Emerl to train with him. 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 cannons for arms. When Delta was sent away along with E-104 Epsilon and E-105 Zeta, he looked sadly at his brother, E-102 Gamma. Later, Gamma found Delta stranded in Windy Valley. The two brothers battled, and Gamma emerged victorious. Delta fell over and exploded. In the original Sonic Adventure, Delta's animal was a green flicky bird, but in Sonic Adventure DX, the animal was changed to a parrot. At first, Delta was based off Gamma with one cannon arm, but after being discarded by Eggman, he is based on Beta, meaning he had two cannon arms and a jet pack.

E-104 Epsilon (ε)

E-104 Epsilon is an orange robot with STINGER missile launchers for arms. Epsilon was teleported to an unknown location along with Delta and Zeta. Later, Gamma found E-104 Epsilon in a lava filled cave (the Red Hot Skull area) in Red Mountain. The two fought, and Gamma emerged victorious. The yellow flicky inside Epsilon managed to escape. 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.

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. A Dreamcast console is included in Zeta's exterior design, inserted by Sonic Team as an Easter Egg. This is in both the Dreamcast and GameCube 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)

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. There is a mistake in numbering the Phis for according to the Greek alphabet, Phi is the twentyfirst letter, so they should be numbered E-120, much like all of the other E-100's were named by their letter according to the letter's order in the Greek alphabet minus one.

E-123 Omega (Ω)

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, he swears vengeance on Eggman for shutting him down. Omega is seen again in Shadow the Hedgehog and he and Shadow infiltrate Eggman's base towards the end of the neutral story. He is also playable in Shadow the Hedgehog 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 posesses stronger weaponry, and his intentions aren't anywhere near as noble. He stands at about 4 ft 5 in tall, and weighs around 1,584 to 1,980 lb.

Other E-100 Series

If Eggman followed the Greek alphabet for the rest of the series (not including the mistake with Phi) the other robots would be numbered like so:

E-106 Eta (η) E-107 Theta (θ) E-108 Iota (ι) E-109 Kappa (κ) E-110 Lambda (λ) E-111 Mu (μ)

E-112 Nu (ν) E-113 Xi (ξ) E-114 Omicron (ο) E-115 Pi (π) E-116 Rho (ρ) E-117 Sigma (σ)

E-118 Tau (τ) E-119 Upsilon (υ) E-120 Phi (φ) (Is E-121 in-game, which is a mistake.) E-121 Chi (χ) E-122 Psi (ψ)

Sonic Adventure 2 Robots

The only confirmed E-series robot from Sonic Adventure 2 is 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.

Sonic Heroes Robots

Yet 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, which was a tall, red, armored robot sporting directed energy weapons, and the E-2000R, a gold-colored variant of the regular E-2000. The status of "Egg Pawns" and other robotic enemies featured in Sonic Heroes as members of the E-series line has yet to be confirmed by any official sources; the only Sonic Heroes E-series robots to be officially confirmed in-game or by other sources are the aforementioned E-2000 robots and the notable E-123 Omega, who was an individualistic playable character, much like E-102 Gamma.

Sonic Riders Robots

Sonic Riders features 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 Egg Pawns, but more advanced and equipped with speech capabilities. 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. It is rumored that they were built out of the parts of Metal Sonic, or at least based on Metal Sonic's schematics, but this isn't elaborated upon in the game and is debatable. Also, exlcuding E-10000G and E-10000R, when some of the robots appear on the Egg Factory/Ice Factory courses, they have no feet (they have legs), nor boards, and are not playable characters.

E-10000R

E-10000R, also known as "Robo 1," is the red version of the E-10000 series. "R" is red, and is quite fast, making him a speed type. A nickname some have given him is "Robo Red" or "Elor," as they pronounce the 10000. His unique Extreme Gear is called the E-GearR. You unlock him by playing for 50 hours.

E-10000G

Like his brother, "G", or Robo 2, is the green version of the E-10000 series. "G" is a power type. He, like R, was given a nickname, "Robo Green." His unique Extreme Gear is called the E-GearG. They appear whenever other characters aren't in a race.

E-10000B

E-10000B is a robot seen in the Egg Factory used as an obstacle. It is tall, bulky and blue in color. Some have also referred to him as E-10000P, thinking his hue is a more purple color.

E-10000Y

E-10000Y is a robot seen in the Egg Factory used as an obstacle. He is small and yellow, and his main purpose appears to try and capture intruders in Eggman's base.

E-10000O

E-10000O is a robot seen in Ice Factory. He is, like E-10000Y, used as an obstacle. He is tall and orange in color, and his job is to spray ice around the factory.

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 listed them as "Robo 1" and "Robo 2") The Japanese website fixed this, 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. However, in Story Mode, E-10000G can grind on the rails as though it's a speed character, as well as fly by moving on flight ramps, as though it was a flight character.

Sonic X Robots

Several robots from the E-Series appeared in the television series Sonic X. (Given differences between the Sonic X continuity and the continuity of the games, there may be some conflict between numbers.) They are as follows:

• E-11 Beacon - Sonic X 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 Dreamer - Sonic X Episode 28
• E-13 Guardbot - Sonic X Episode 1
• E-14 Sneezer - Sonic X Episode 1

• E-18 Guerra-Hard - Sonic X 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. Bears a striking resembelance to the Super Robot Mazinger Z.
• E-21 Ballion - Sonic X Episode 10: Baseball Bots. 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.
• E-23 Missile Wrist - Sonic X Episode 3. Eggman unleashes it to cause havoc in Station Square, only for it to be destroyed by Sonic. Missile Wrist is equipped with missile-like grappling hooks attached to retractable cords in place of its hands.
• E-35 Funfun - Sonic X Episode 12
• E-38 Octoron - Sonic X Episode 9
• E-39 Quizon - Sonic X Episode 9
• E-40 Egg Fortress - Sonic X Episode 15
• E-42 Torole - Sonic X Episode 15
• E-43 Falcon - Sonic X Episode 15
• E-45 Sumo - Sonic X Episode 21. Eggman sends Sumo, an extremely stupid robot, to stop Sonic from winning a race with Sam Speed. Too big and slow to catch Sonic, Sumo takes it out on himself, hitting himself in the face. Underestimating his own strength, Sumo is sent flying and crashes into Eggman's base.
• E-47 Pumpty - Sonic X Episode 5. Not to be confused with Humpty, a robot from AoStH and Dr. Robotnik's Mean Bean Machine.
• E-51 Intelligente - Sonic X 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, and the weaponless robot was destroyed by Sonic.
• E-57 Clurken - Sonic X Episode 16
• E-65 Gorru-Gaooh - Sonic X Episode 18
• E-66 Da-Dai-Oh - Sonic X Episode 22
• E-70 Noizi - Sonic X 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.
• E-74 Weazo - Sonic X Episode 23. A giant 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.
• E-77 Lucky - Sonic X 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, his opponents never showed up or were forced to leave before fighting began. Unfortunately, his luck ran out when he had to face Emerel, as its victory dance burned out the remaining energy in his power cells and subsequently shut-down.
• E-88 Lightning Bird - Sonic X Episode 24
• E-90 Super Sweeper - Sonic X 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.
• E-91 Lady Ninja - Sonic X 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. 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.
• E-99 Eggsterminator/Egg Fort 2 - Sonic X Episode 26. The robot form of the Egg Fort 2, 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.
