The Egg Mobile (エッグモービル eggumōbiru?), originally known as the Eggman Mobile (エッグマンモービル eggumanmōbiru?), is a one-man hovercraft created and very frequently piloted by Dr. Eggman as his preferred mode of transportation. The Egg Mobile is known to be colored grey with many features and details. It is also known for its universal compatibility to combine with various of Eggman's vehicles and creations. It also comes in various versions as its design is usually varying from game to game.
Along with its creator, the Egg Mobile made its first appearance in the original 16-bit version of Sonic the Hedgehog. In numerous games since then, the Egg Mobile has been seen as cockpit or part of a boss vehicle at the end of the Zones and is usually known to be weak point of the bosses in general. In several games, it is also featured as a playable racing or combat vehicle.
There are various versions of the Egg Mobile, as in the games it varies from game to game. Universally, it is a small hovering craft with a very distinct egg-like shape. Other well known features of the Egg Mobile are known to have black and yellow hazard stripes on the sides of the craft, black circular hemispherical underside, rocket engines behind the mobile to keep it moving and a small circular lamp on the front. The cockpit itself is seen to have a driving seat, a small windshield and the cockpit's control system.
The Egg Mobile can be fitted with a seemingly endless amount of gadgetry. Not only does the doctor use it as his mode of transportation but also as the cockpit of even larger doomsday devices and machines. When these are destroyed, Eggman and his mobile will inevitably emerge relatively unscathed from the wreckage. Usually the cockpit is the only weakness during many boss battles. In several games, the most used gadgets of the Egg Mobile are known to be a checkered wrecking ball suspended by chain or claw attachment, that is seen caring larger items at the bottom of the mobile such as the Master Emerald, Capsule or any other item.
As the boss of every Zone/stage, Dr. Eggman appears at the end of most levels in his Egg Mobile, with new attachments. In most Master System and Game Gear games, Robotnik does not appear as a level boss, instead using larger Badniks and being himself as final boss, as sometimes Egg Mobile doesn't appear in those games without any add-on vehicles. In many recent games, the Egg Mobile is featured in cutscenes as well, even usually described being able to travel from one place to another.
Sonic the Hedgehog (16-bit)
Egg Mobile first appears in the original 16-bit version of Sonic the Hedgehog. It is described as hovering, grey pod and its lower part is completely black. Egg Mobile does have two yellow, mechanical feet for mobile's landing support. In the middle front mobile has single headlight. Each side of mobile does have air seals, small wings, horizontal black and yellow stripes and one motor behind the mobile which is protected from the top with yellow metal shield. It does have low windshield and blue driving seat.
The Egg Mobile's add-ons are simple, sometimes to the point of being minor weapons on an otherwise unequipped Egg Mobile. The Egg Mobile has featured below:
- Green Hill Zone: Green Hill Zone boss (hammer ball)
- Marble Zone: Marble Zone boss (fireball spitter)
- Spring Yard Zone: Spring Yard Zone boss (spike drill)
- Labyrinth Zone: Labyrinth Zone boss (trapped retreat)
- Starlight Zone: Star Light Zone boss (mine dropper)
After the encounter in Starlight Zone, the Egg Mobile does not appear in the game until at the end of Robotnik's final confrontation in Final Zone. Robotnik used it as trying to escape quickly after Sonic had defeated the final machine. During this player can do a finishing move to damage the Egg Mobile, leading to Robotnik barely flying away in his own smoke. This, however, is entirely optional and has no effect on anything.
Sonic the Hedgehog (8-bit)
Egg Mobile appears normally at boss fights in the 8-bit version of Sonic the Hedgehog, like in its 16-bit counterpart. The game also features a submarine-type Egg Mobile twice, as its cockpit was replaced with a metallic shelter with two tubes of each side which fires small trios of energy balls, and a small window where Robotnik can see the outside. The Egg Mobile was featured below:
- Green Hill Zone: Eggman Mobile
- Bridge Zone: Bridge Zone boss (submarine)
- Jungle Zone: Jungle Zone boss (bowling bombs)
- Labyrinth Zone: Bridge Zone boss (underwater rematch)
Egg Mobile doesn't appear in Scrap Brain or Sky Base Zone. At the end of game, after Robotnik got defeated by Sonic in Sky Base Zone, he escaped by teleporting to Green Hill Zone only to get struck down by a spinning Sonic who also teleported above Robotnik's head.
Sonic the Hedgehog 2 (8-bit)
The Egg Mobile appears briefly in the 8-bit version of Sonic the Hedgehog 2 as it is based on original Egg Mobile from first game. It first appears at intro of the game, where Robotnik kidnaps Tails with a yellow grabber attachment (which would later make infrequent appearances in the series).
It later appears at Act 3 of Under Ground Zone, where Sonic falls to the lava and Robotnik actually saves him with black claw that is set under the mobile (which later becomes horizontally rotating rotor), only to prevail upon the close of zone's boss, Arijigoku Mecha. Robotnik then on off-screen starts to fire bouncing bombs to Sonic, which only explodes on Arijigoku Mecha's mouth. At the end Robotnik tries to drive towards Sonic but crashes on Arijigoku Mecha, which finishes it off and Robotnik flies away with his Egg Mobile. The Egg Mobile does not appear in the game after this as the rest of the Master Robot series takes its place.
Sonic the Hedgehog 2 (16-bit)
The Egg Mobile makes its return in the 16-bit version of Sonic the Hedgehog 2, this time getting redesigned to look sleeker and more mechanical. The front of mobile is circular, which has small windshield. Each of mobile's side has horizontal black and yellow stripes, tail pipes that curved upper horizontal direction and small wings that has air seals under them and small motors behind them. The behind of mobile has registration plate, which license code states "EGG". The Egg Mobile has circular back plate, which protects the cockpit from behind. The cockpit has foot switch, steering wheel and brown driving seat.
There's few features that are rarely used in the Egg Mobile. Metropolis Zone's fight features green headlight, which fires yellow lasers. Also at the beginning and ending of Emerald Hill Zone fight, Egg Mobile used horizontally rotating rotor to landing and escaping. The Egg Mobile has forms featured below:
- Emerald Hill Zone: Drill Eggman
- Chemical Plant Zone: Water Eggman
- Aquatic Ruin Zone: Tonkachi Eggman
- Casino Night Zone: Catcher Eggman
- Hill Top Zone: Submarine Eggman
- Mystic Cave Zone: Drill Eggman II
- Oil Ocean Zone: Submarine Eggman II
- Metropolis Zone: Flying Eggman
After the conformation at Metropolis Zone, the Egg Mobile doesn't appear in rest of the game, such as at Sky Chase Zone (which has no boss), Wing Fortress Zone (in which Robotnik controls a contained death trap instead of attacking himself) or even in Death Egg Zone which features Mecha Sonic and the final boss, Death Egg Robot. In the 2013 mobile re-release, the player can also fight Brass Eggman at Hidden Palace Zone, skipping the Mystic Cave confrontation.
SegaSonic the Hedgehog
The Egg Mobile appears briefly in SegaSonic the Hedgehog, having a design from first Sonic the Hedgehog game. It is seen at the title screen of game as Robotnik is flying in the background. Another time is at the small ending cutscene after the credits, where Robotnik flies in middle of the ocean until the Egg Mobile stops moving due to the lack of fuel and falls to the ocean with Robotnik screaming.
Sonic the Hedgehog CD
Sonic the Hedgehog CD features a few different models of the Egg Mobile. Egg Mobile is featured in the following boss battles:
- Collision Chaos: Collision Chaos Boss
- Tidal Tempest: Tidal Tempest Boss
- Stardust Speedway: Metal Sonic (race)
The main Egg Mobile model was featured in the Collision Chaos duel, where it was part of the pinball machine he was using the escape, and slow Sonic at the same time. In comparison to the first model, it was lower and thinner at bottom. At the front it had a grey Eggman decal, instead of two headlights. It had four propulsion jets on it, one on its back and the other three on its underside, which activate and deactivate depending on which direction Eggman is flying (for example if Eggman if flying forward the jets behind, just below it diagonally, and the middle jet facing down will be activated, while the one that is pointing in Robotnik's forward direction will not be activated).
The same Egg Mobile later appears at Tidal Tempest, as at first Eggman tries to outrun Sonic in a maze (similar to the escaping in Labyrinth Zone, but the maze has no traps to speak of, no water hazard and goes down), and after taking four hits, retreats to an underwater arena, where it activates a shield cup above the cockpit and generates a barrier of bubbles to protect itself from Sonic, who is left to drown (though the idea behind this tactic is flawed, as Sonic can merely jump to the Egg Mobile to both weaken the shield and supply himself with air). A mere hit to the Egg Mobile itself will cause it to retreat from the level.
It later appears in Stardust Speedway. As Sonic races Metal Sonic, Eggman merely follows behind using a very powerful laser ready to toast (instantly kill, regardless of rings) the one that slows down for too long (mainly Sonic, as he never can catch up with Metal Sonic). If Sonic wins, a door closes behind leaving Metal Sonic to be destroyed (though it not easy to tell in game if Metal Sonic is destroyed by the laser or the impact of the Egg Mobile crashing in to the door at full speed). Eggman deactivates the laser after it impacts the door and retreats, leaving Sonic to rescue Amy Rose.
The Egg Mobile is not featured in the Palmtree Panic, Quartz Quadrant, Wacky Workbench and Metallic Madness fights as the machines are independent and Eggman is controlling them without the Egg Mobile being added on. This can be seen as sometimes Eggman runs away after the fight. After the final duel at Metallic Madness, Eggman escapes from Little Planet with yet another kind of transportation craft (though with his craft on fire) and being ready to fight another day. Eggman is also seen using this craft in the background of DA garden feature.
Sonic the Hedgehog Spinball
The Egg Mobile is featured at the Bonus Stage of the 16-bit version of Sonic the Hedgehog Spinball, based on the Sonic the Hedgehog 2 design. At Bonus Stages, the player has to destroy all purple capsules behind the Egg Mobile with their pinball skills and then blow the mobile itself, leaving Robotnik fainted on ground. If you try to blow the Egg Mobile before blowing purple capsules, it will bounce the ball back. It is also the final weapon in the 8-bit version of Showdown.
The cubic-shaped Egg Mobile appears in the intro and bad ending sequences of Sonic Chaos, as Dr. Robotnik away with the Red Chaos Emerald in its grabber gadget. Sonic and Tails runs behind him, but he gets away. One of bosses, the Bouncy Boss Robot is basically an Egg Mobile which has a robotic Robotnik drone firing projectiles and bouncing towards the player.
Sonic Drift Series
In the racing games Sonic Drift and Sonic Drift 2, Dr. Robotnik drives a racing vehicle based on the Egg Mobile, called the Egg Typhoon-gou or just the Egg Typhoon. The Egg Typhoon itself is loosely based on the Egg Mobile's design from Sonic the Hedgehog 2 without the wings, tail pipes and circular back plate. In the games, the Egg Typhoon has good top speed, but poor acceleration, and can drop mines to distract the other racers.
Sonic the Hedgehog 3 & Knuckles
The Egg Mobile makes an appearance in both Sonic the Hedgehog 3 and its add-on continuation Sonic and Knuckles with another different design. The Egg Mobile in these games is smaller and simplistic than earlier designs. This Egg Mobile doesn't have wings at all but instead has two tail pipes. The Egg Mobile's cockpit doesn't have a windshield at all and has a small yellow driving seat, which is supported by a pole behind it.
As the Egg Mobile is small, it has a tendency to use large armored shells that hide the hovercraft itself. The Egg Mobile also has its own gadgets as well. At certain times, the Egg Mobile has glass covers above the cockpit. In Hidden Palace Zone, Robotnik uses its yellow claw which is set beneath the mobile to steal the Master Emerald from the altar. When Knuckles tries to stop him, Robotnik releases two electric whips that are capable of delivering an electric shock.
In addition to boss battles, the Egg Mobile has also been featured in some scenes as the Robotnik brings the sub-boss of Launch Base Zone to its place and releases for battle. At the end of Sonic the Hedgehog 3, after the first Launch Base Zone boss, Sonic or Tails can ride with an Egg Mobile which was parked right behind the boss fight to reach the relaunching Death Egg. With lock-on technology, Knuckles can't access this area (however the player can do this with Debug Mode). The Egg Mobile has forms featured below:
- Angel Island Zone: Flame Mobile
- Hydrocity Zone: Screw Mobile
- Marble Garden Zone: Drill Mobile
- Carnival Night Zone: Graviton Mobile
- Ice Cap Zone: Freezer Mobile
- Launch Base Zone:
- Mushroom Hill Zone: Jet Mobile
- Flying Battery Zone: Hang Mobile
- Sandopolis Zone: Egg Golem (Sonic & Knuckles)
- Lava Reef Zone: Hot Mobile
- Sky Sanctuary Zone:
- Death Egg Zone: Egg Mobile (second retreat attempt)
The Egg Mobile wasn't featured at Death Egg Zone's second sub-boss, as Robotnik controls it from the other side of the tube. While playing as Knuckles, an Eggrobo usually takes Robotnik's place in the Egg Mobile until he and its mobile get destroyed by Mecha Sonic. While playing as Sonic (or Tails), Mecha Sonic uses the Egg Mobile twice in Sky Sanctuary Zone..
Several upgraded Egg Mobiles are used by Robotnik as bosses in the game.
- Botanic Base: Botanic Base boss
- Amazing Arena: Amazing Arena boss
- Marina Madness: Marina Madness boss
Sonic 3D Blast
In Sonic 3D Blast, the Egg Mobile is featured in the third act of each Zone. It has simple design from previous games, while it is seen to have rocket engines on each side of the mobile and aiming down instead of back. The Egg Mobile is upgraded with small attachments or weapons. During the battle, the player has to reach on the cockpit in order to hit Robotnik and when the player does it couple of times, the glass dome above the mobile starts to breakage and worn out. The Egg Mobile has featured below:
- Green Grove Zone: Green Grove Zone boss (spike ball dropper)
- Rusty Ruin Zone: Rusty Ruin Zone boss (armored titan)
- Spring Stadium Zone: Spring Stadium Zone boss (long spiked arms)
- Diamond Dust Zone: Diamond Dust Zone boss (chilling unit)
- Volcano Valley Zone: Volcano Valley Zone boss (lava processor)
- Gene Gadget Zone: Gene Gadget Zone boss (missile launcher)
- Panic Puppet Zone: Panic Puppet Zone boss (multipurpose weapon)
In Sonic R, Dr. Robotnik is an unlockable playable character where he uses the Egg Mobile as a racing vehicle, similar to the Egg Typhoon in the Sonic Drift games. The Egg Mobile in this game has the basic appearance for the Egg Mobile without many details. It has great steering, good acceleration and is able to hover over the water sections, but it has low speed and no grip. To unlock Robotnik and his Egg Mobile, the player has to come in first place in the first four race courses.
Robotnik and his Egg Mobile's main weapon in the game is the homing missile, which the player can fire by pressing the A, C, or Y button when the target reticle is green. To lock onto the target, the player has to aim precisely. It also takes ten Rings from the player's score and has brief recharge after launching the homing missile.
In Sonic Adventure, the Egg Mobile retains its basic design but, like the characters themselves, has been updated to look more like a semi-realistic functional vehicle. Most notable is the trio of thrusters positioned behind Eggman's head. Eggman appears multiple times throughout all the player characters' storylines usually riding the Egg Mobile. It is battled two definite times, with add-ons and assists in Sonic's battle with Chaos 6 throughout the course of the game.
During the first visit to the Mystic Ruins in both Sonic's and Tails' storylines, the Egg Mobile appears just in front of Tails' Workshop. After brief banter, it hovers down under a cliff, fitted as the Egg Hornet. The add-ons include much larger thrusters added to the back, rocket launchers, and a pair of thunder 'stingers' on either side. After the battle, without the Egg Hornet attachments, it is shown to have a built-in extend-able clamp, delicate enough to snatch a Chaos Emerald right out of Tails' hands.
Just after the Casinopolis stage for Sonic and Tails, the Egg Mobile appears again. This time, it sprays a knock-out gas on our heroes before any boss battle can begin and uses the clamp to take another emerald.
Just before the battle against Chaos 4 for Sonic, Tails, and Knuckles, the Egg Mobile arrives and steals the emeralds Knuckles just knocked out of Sonic or Tails, this time using a green beam. At the end of said battle, Dr. Eggman "beams aboard" the Egg Carrier in the Egg Mobile. It is unclear whether the green beam of light shining from the Egg Carier was what propelled the flight or whether it was the Egg Mobile.
During Sonic's battle against Chaos 6, Eggman and the Egg Mobile assist Chaos. There are no attachments added to the Egg Mobile, though Eggman launches freezing robots at Sonic.
At the end of Tails' storyline, in front of Casinopolis, comes the Egg Walker, the Egg Mobile attached to four large walker legs. After Eggman loses, he retreats to Final Egg with Egg Mobile while Sonic discovers him and follows him there. The Egg Mobile does not make an active appearance during the Egg Viper boss at the end of the Final Egg, although Eggman is seen flying away with Egg Mobile at ending scene of Sonic's story. The Egg Mobile is also seen at final story of the game, when Eggman discovers Chaos prior the creature's betrayal and the epilogue after the battle against Perfect Chaos.
Sonic the Hedgehog Pocket Adventure
The Egg Mobile in Sonic the Hedgehog Pocket Adventure comes in two different designs throughout the game. The Egg Mobile's first design resembles the one it had in Sonic the Hedgehog 2 and can be seen as a part of the boss vehicles at the end of each Zone's second act. This design for the Egg Mobile is last seen in Aquatic Relix when Eggman steals the Chaos Emerald from Sonic's hands and then flies to Gigantic Angel Zone.
At the end of the game, the Egg Mobile in the final vehicle of Last Utopia Zone has the design it had in the original Sonic the Hedgehog. In the regular ending, Eggman tries to escape in the Egg Mobile, but Sonic's final Spin Jump blows up the Egg Mobile and send it falling down to Earth. If the player got all the Chaos Emeralds in the game, however, Eggman flies away in his Egg Mobile to his final weapon at Chaotic Space Zone. After the battle, Super Sonic gives the finish move and Eggman flies down to Earth with a exploding Egg Mobile. The Egg Mobile boss battles are remarkably similar to the following boss machines:
- Neo South Island Zone: Egg Hammer Tank
- Secret Plant Zone: Egg-Go-Round
- Cosmic Casino Zone: Catcher Eggman
- Gigantic Angel Zone: Aero Egg
- Last Utopia Zone: EGG X
Sonic Adventure 2
In Sonic Adventure 2, where Dr. Eggman is playable, he rides a modified Egg Mobile, which has become a "chicken walker" mech called the Eggwalker. It has a pair of backward-jointed legs added, a machine gun to one side and a rocket launcher perched above Eggman's head. The two battles against Eggman are fought against this mode.
The traditional flying Egg Mobile does show up during certain cut scenes, such as the one introducing Knuckles and Rouge. In it, he once again uses a yellow claw in an attempt to take the Master Emerald. While Knuckles manages to break the Master Emerald into shards at the time, Eggman escapes back to the pyramid base.
Sonic Advance Series
The Egg Moile reprised its role from the classic games in all three Sonic Advance titles. The Egg Mobile in the first two Sonic Advance titles is rather small with a small windshield and two red and grey colored rocket engines on each side of its back. When the Egg Mobile turns around, it is shown having small pipes with blue fire coming out on the Egg Mobile's downside.
At the end of Neo Green Hill Zone Act 2 in Sonic Advance, the player first encounters Eggman on his Egg Mobile. After each boss fight, Eggman can be seen flying away in his Egg Mobile. In X-Zone, the Egg Mobile is given its design from the original Sonic the Hedgehog and Sonic the Hedgehog 2. The Egg Mobile in Sonic Advance is featured below:
- Neo Green Hill Zone: Egg Hammer Tank
- Secret Base Zone: Egg Press
- Casino Paradise Zone: Egg Ball
- Ice Mountain Zone: Egg Spider
- Cosmic Angel Zone: Egg Snake
- X Zone:
- The Moon Zone: Super Egg Robot
In Sonic Advance 2, the Egg Mobile once again resumed its role from the classic games, functioning as an escape vehicle for Eggman. The Egg Mobile is featured below:
- Leaf Forest: EggHammerTankII
- Hot Crater: Egg Bomber Tank
- Music Plant: Egg Totem
- Ice Paradise: Aero Egg
- Sky Canyon: Egg Saucer
- Techno Base: Egg-Go-Round
- Egg Utopia: Egg Frog
- All bosses from previous stages.
- Super Eggrobo Z
In Sonic Advance 3, the Egg Mobile is given slightly different design, having more jet plane-looking appearance with two rocket engines and small red lower wing at the Egg Mobile's bottom. It once again reprises its role from the classic games and during the boss battles, Gemerl merges together with the Egg Mobile to be a part of Eggman's machines until the end of the game. Egg Mobile is featured below:
- Route 99: Egg Hammer 3
- Sunset Hill: Egg Ball No.2
- Ocean Base: Egg Foot
- Toy Kingdom: Egg Cube
- Twinkle Snow: Egg Chaser
- Cyber Track: Egg Pinball
- Chaos Angel: Egg Gravity
- Altar Emerald: Hyper Eggrobo
In the bad ending, the characters destroys the Eggman's Egg Mobile after the final boss, sending it plummeting down, while in the good ending (if the player has got all the Chaos Emeralds), Super Sonic and Eggman teams up against the Ultimate Gemerl at Nonaggression, where the only thing that can damage Ultimate Gemerl is the Tag Action with Eggman where Super Sonic load and fires Eggman in his Egg Mobile into the eye of Ultimate Gemerl to open its eye for Super Sonic to damage it. After the battle, Eggman carries the tired Super Sonic back to the Emerald Altar and flies away with the Egg Mobile, as Tails mentions about it to Sonic.
Sonic Pinball Party
In Sonic Pinball Party, the Egg Mobile appears above one of the chao holes on the Sonic Board in Egg Mode. To go to the next stage Eggman must be defeated by putting the pinball in the hole a set number of times. During the game, the Egg Mobile is seen to have similar appearance from original Sonic the Hedgehog.
In this game, the design of the Egg Mobile is drastically changed; the main difference is that it no longer has engines in the back, but instead has some kind of propulsion system located at its bottom where ring-shaped beams are constantly being dissipated from it. This design has only appeared in two games (Sonic Heroes and Shadow the Hedgehog) and has since been replaced with the design that was reused from Sonic Adventure.
Throughout the game, the Egg Mobile is seen being attached to a larger battle mech three times for a boss battle; in the first two battles, Neo Metal Sonic manages to escape from destroyed battle mech at the end of fight. It is also seen in the background during Robot Carnival and Robot Storm where Neo Metal Sonic is commanding his troops. The Egg Mobile is featured below:
In Sonic Battle, the Egg Mobile is only seen during the fight against Eggman on Death Egg's battle arena in the final story of the game. In this game, the Egg Mobile is mostly colored red with a black hemispherical underside and two cannons on each side.
During the battle against Eggman in the Egg Mobile, Eggman has five lives. In battle, Eggman fires numerous missiles all over the place which can knock the player into the air, which the player can avoid by running around the wide arena. Eggman can also drop exploding bombs below the Egg Mobile. When knocked into the air, the Egg Mobile slowly lands back down. When the Egg Mobile gets destroyed, it explodes and causes damage to Emerl if he is too close to Eggman.
Shadow the Hedgehog
The Egg Mobile in Shadow the Hedgehog features the same design it had in Sonic Heroes and is seen being piloted by Eggman. The Egg Mobile is only seen twice in the cutscenes in the game, namely in those before starting Cryptic Castle and Iron Jungle, where Eggman is seen giving commands to Shadow Androids from the Egg Mobile. It is also used to pilot the Egg Breaker or the Egg Dealer.
Sonic Rush Series
In both Sonic Rush and Sonic Rush Adventure, the Egg Mobile was the featured vehicle for both Dr. Eggman and Dr. Eggman Nega, with each of them having their own Egg Mobile. In these games, the design of the Egg Mobile is recycled from Sonic Adventure and the only difference between Eggman and Eggman Nega's Egg Mobile is their color schemes; Dr. Eggman's Egg Mobile is grey and yellow, while Eggman Nega's mobile is yellow and red.
In Sonic Rush, both Eggman and Eggman Nega used their Egg Mobiles as cockpits in their larger mechs for boss battles by attaching them to these machines and the only weak point of these machines are the Egg Mobiles' glass dome. Once these machines are defeated, Eggman and his Egg Mobile gets kicked away by Blaze the Cat (if fighting them for the first time) or escape from the battle with the Egg Mobile in a poor condition. One of the doctors is also seen watching the battle between Sonic and Blaze from the Egg Mobile in the background. Despite not taking part in the fight, the doctor (depending on the player's character) strangely flees away in the Egg Mobile in the same manner of that in the previous boss fights. Either one of the doctors' Egg Mobile is featured below:
- Leaf Storm: Egg Hammer Mega
- Water Palace: Egg Turtle
- Mirage Road: Egg Scarab
- Night Carnival: Egg Libra
- Huge Crisis: Egg Hammer Fortress
- Altitude Limit: Egg Eagle
- Unknown: Egg King
In one of the last single cinematic cutscene in Sonic Rush Adventure, Eggman is seen flying in the Egg Mobile alongside the Egg Wizard, before he and Eggman Nega both start using the Egg Wizard to go after the Power of the Stars).
Sonic Riders Series
The Egg Mobile in Sonic Riders and Sonic Riders: Zero Gravity reuses the same design that is seen in Sonic Adventure. In Sonic Riders, it is seen being used when Eggman visits on the Babylon Rogues' hideout and when he uses the grabber attachment to snatch the key to Babylon Garden away from Jet's hand and flies to the risen Babylon Garden with Egg Mobile (while in the next cutscene when Sonic and co. finds out Eggman at the Babylon Garden, he has switched his transportation vehicle from Egg Mobile to E-Rider). In Sonic Riders: Zero Gravity, Eggman is briefly seen piloting it while being chased by Babylon Rogues' airship, after Sonic and co. finds out the truth about Arks of the Cosmos at Gigan Rocks or (in the Babylon's story's case) the Babylon Rouges discovered that Eggman has stolen the Arks of the Cosmos and takes off in the Egg Mobile, with the Babylon Rouges' airship following right behind it.
Sonic the Hedgehog (2006)
In Sonic the Hedgehog (2006), the Egg Mobile features a design completely different from all its other known game appearances. In this game, it is a completely gray/silver vehicle that is shaped as a long oval and is big enough to walk at least 20-30 feet on. Another huge difference is that this Egg Mobile has two large detachable and remotely controlled hands that Eggman uses at numerous times throughout the story of the game to kidnap Elise.
The only time when Egg Mobile is ever show being utilized in combat is when it attached itself to the Egg Wyvern, the final boss in the Sonic's story. During the fight, the arm parts on the Egg Mobile can chang into laser cannons. Occasionally, the player has to hit Egg Mobile's cockpit when the Egg Wyvern's upper part opens and Eggman charges laser cannons, which can be used to reach the cockpit with the Homing Attack. After the battle, the Egg Mobile is destroyed along the Egg Wyvern, while Eggman escapes as the Egg Mobile seat is rejected from the Egg Mobile.
Sonic Rivals 2
In Sonic Rivals 2, Eggman Nega, under the disguise of Dr. Eggman, pilots the Egg Mobile as a part of almost every boss vehicle in the game. The Egg Mobile can be briefly seen when the player destroys one of the bosses as it flies away.
The design of his Egg Mobile in this game is drastically different from its previous designs. It has a tubular design with four rocket engines aiming down at the Egg Mobile's sides. To defeat a boss machine, the player usually has to hit the machine's glass dome six times before the rival character does it. The Egg Mobile is featured below:
- Blue Coast Zone: Egg Liner
- Sunset Forest Zone: Egg Crawler
- Neon Palace Zone: Egg Dealer
- Frontier Canyon Zone: Egg Bull
- Mystic Haunt Zone: Egg Phantom
In Sonic Unleashed, the Egg Mobile received another new design. The design of this Egg Mobile features the traditional black and yellow hazard stripes on the sides of the Egg Mobile and two back engines with an extra one set on the black hemispherical underside that can fold out. The front of the Egg Mobile has large a bolt on both the center's sides and two different sized glass lamps along the center. It also has a windshield and a retractable glass-like dome to protect Eggman during space travels and his battles against Sonic. Notably, the Egg Mobile is also given a detailed interior, featuring a plush seat for Eggman to sit in while piloting it and two handles for piloting it. This design has since then been the most recent and recurring design for the Egg Mobile.
In the beginning of Sonic Unleashed, Eggman piloted a large prototype mech from his Egg Mobile, which had been attached to the mech, and engaged with it in battle with Sonic when he arrived on the central battleship of the spacial Eggman Fleet. After being defeated by Super Sonic, Eggman escaped in the Egg Mobile to the Chaos Energy Cannon, while Super Sonic chased him through his space armada. At the Chaos Energy Cannon, Eggman got to the main room of the cannon, while tumbling out of the Egg Mobile after losing the control while Super Sonic arrived. When Eggman tricked Super Sonic into the center of the cannon and used him to awaken Dark Gaia, Eggman sought refuged inside the Egg Mobile again before opening a window into space, throwing Sonic the Werehog out the Chaos Energy Cannon.
After that, Eggman is seen using the Egg Mobile as his main transporting vehicle in several of the cutscenes through the game. The Egg Mobile is featured below, though in PlayStation 3/Xbox 360 version, Eggman is replaced with Little Fighters piloting the Egg Devil Ray and the Egg Lancer:
After Sonic defeated the Egg Dragoon and ended up in the center of the Earth, Dark Gaia appeared and Eggman, in the Egg Mobile, commanded it to destroy Sonic and Chip, only to get smashed smashed away and sent to the surface of the Earth. At the end of the game, Eggman and Orbot had crashed in a deserted rocky land with his Egg Mobile.
Sonic the Hedgehog 4
The Egg Mobile in Sonic the Hedgehog 4: Episode I has a slightly different design that looks similar to one it had in the original Sonic the Hedgehog. It has more of a white color scheme, longer wings on the sides and its hemispherical underside function as hatch. It also has a heavier pilot seat in the cockpit. During the the game, the Egg Mobile mostly adapts Dr. Eggman's old inventions from the original Sonic the Hedgehog and Sonic the Hedgehog 2 with new strategies. The Egg Mobile is featured below:
- Splash Hill Zone: Hammer Ball
- Casino Street Zone: Catcher Eggman
- Lost Labyrinth Zone: Labyrinth Zone boss
- Mad Gear Zone: Flying Eggman
- E.G.G. Station Zone: All bosses from previous Zones.
The Egg Nobile in Sonic the Hedgehog 4: Episode II looks the same as it did in Sonic the Hedgehog 4: Episode I, but has gotten a few new inventions to adapt itself with. The Egg Mobile also shows new ways to merge with Eggman's creations (for example by using a magnet add-on that can be used to fuse scrap metal into a robot). At some point during the Sky Fortress Zone, Eggman rejected the Egg Mobile and used a rocket pod to travel to the Death Egg Mark II, were he has another Egg Mobile ready. In the Death Egg mk.II Zone, Metal Sonic and Eggman in his Egg Mobile teams up to fight Sonic and Tails. The Egg Mobile is listed below:
- Sylvania Castle Zone: Egg Serpentleaf
- Oil Desert Zone: Egg Scrap Mech
- Death Egg mk.II Zone:
The Egg Mobile in Sonic Colors has the same design from Sonic Unleashed, though it now features an engraving of the doctor's face on the back. In this game, Eggman only uses it as his main method of transport, aside from piloting the Nega-Wisp Armor. In the mid-point of the game, Eggman also installed the Egg Mobile with a mind control beam when attempting to ambush Sonic, but Tails pushed Sonic out of the way, making it brainwashed him instead. It ran out of Hyper-go-on power before a fight could start, however, resulting in Eggman's retreat. After his defeat against Sonic in the Nega-Wisp Armor, Eggman was unable to control the damaged Egg Mobile as he was sucked into black hole. After the black hole was stopped, Eggman, in his Egg Mobile, was pushed forward by Orbot and Cubot in space to prepare his revenge at Sonic. The Egg Mobile was also alluded to in the Tropical Resort level during gameplay via one of Eggman's recordings. He tries to contact for the owner of a "white hovercraft shaped like an egg" as it was being broken into, only to react with surprise, apparently realizing that it was the Egg Mobile that was being broken into.
After the Death Egg Robot battle, Classic Eggman's Egg Mobile briefly appears before the Time Eater abducted him. As Classic and Modern Sonic, and Classic and Modern Tails confront the Time Eater in the Center of Time, Classic and Modern Eggman reveal themselves as the masterminds behind the Time Eater, both of them sitting in an Egg Mobile that is connected to the head of the Time Eater. After the Time Eater is defeated, both Eggmans lost their Egg Mobile.
Sonic Lost World
In Sonic Lost World the Egg Mobile features the same design it had from previous games. At the beginning of the game, the Egg Mobile was carrying a Capsule that hangs suspended from its underside by the claw through the sky. After discovering that Sonic and Tails on the Tornado were chasing after them, Eggman drops the Capsule and shoots to the Tornado using a beam gun. The Egg Mobile is later seen when Sonic found Eggman at Windy Hill, who then introduced the Deadly Six and commanded Zazz to get rid of him.
Later at Desert Ruins, Eggman, in the Egg Mobile, scolded the Deadly Six for their failures, before Sonic managed to kick the Cacophonic Conch from Eggman's far away, thus freeing the Deadly Six from Eggman's control. The Deadly Six then hijacked the present Badniks and ordered to fire on Sonic and Eggman, while Zazz attacked the Egg Mobile before Zomom smashed it into the ground, forcing Eggman and his lackeys to abandon it. At the end of the game, Eggman managed to get another Egg Mobile and attached it to his ultimate weapon in Lava Mountain for his battle with Sonic, but was defeated once more.
Sonic Boom: Rise of Lyric
The Egg Mobile also appeared in Sonic Boom: Rise of Lyric. Eggman used the Egg Mobile to control his robot against sonic and his friends and to escape after losing the battle.
Appearances in Other Media
Adventures of Sonic the Hedgehog
In the Adventures of Sonic the Hedgehog cartoon series, Dr. Robotnik drove his Egg Mobile in many episodes, except it was under the name the Egg-O-Matic. Often it would be shown with two mini Egg-O-Matics attached to its sides, providing seats for Scratch and Grounder. He also had alterations done to it like in the games, an example being the Egg-o-Matic Tunnelizer and Town Terrorizer. This mobile's design is from the first game without its rarely-seen landed state. The Egg-O-Matic has the design of Marble Zone's boss in Sonic 1, with the flamethrower on the bottom acting as propulsion. Robotnik used a grabber attachment in the episode "Best Hedgehog" to grab Luca. It also appeared in "Grounder the Genius."
In the early issues of the comic series, Dr. Robotnik would fly his Egg Mobile very often. One difference is that it had a manual stick shift, which had an 8-ball for a handle. Recently, the Egg Mobile has been redesigned completely to look different in the games, but has since reverted back to using models based on the games (the very latest being the model seen in Sonic the Hedgehog 4 in issue 225).
Sonic the Hedgehog: The Movie
During the movie, Dr. Robotnik used a completely redesigned mobile, which was not given a name, The mobile was colored yellow and purple and has two big jet engines on both sides of mobile. It also has two rocket launchers at the front with animal shaped missiles- consisting of a tortoise and a hare. Whilst the hare missile proved to be fast and succeeded in shooting down the Tornado, the tortoise missile was incredibly slow, causing Dr Robotnik to lament it as "another design failure".
In Sonic X, a few alterations were made to the Egg Mobile. It retains its spherical shape, but unlike the more recent Egg Mobile designs it has small red wings. There is also a long spike at the bottom that is surrounded by a circle shaped hole. Both were made for unknown reasons, although they could be used to maintain flight as there are no thrusters on this Egg Mobile. Missiles and lasers are located in the body of the craft instead of being released by accessories.
In episode 28, "A Chaotic Day", Eggman makes the Egg Hornet by attaching the big thrusters and drills so he could attack Sonic and Tails. The Egg Hornet looks identical to how it did in Sonic Adventure; it no longer has its wings and the bottom spike. When Sonic and Tails defeat the Egg Hornet, the attachments get destroyed just like in Sonic Adventure; when the smoke dissipates, the Egg Mobile looks like its regular Sonic X appearance again. The spike on the bottom is either retractable or the shell of the Egg Hornet was bigger than the Egg Mobile, since the spike and the surrounding hole disappeared during the fight.
According to its eyecatch card profile, it has a length, breadth and height of 2.8 meters and weighs 5.6 tonnes.
Sonic X Trading Cards
In the Sonic X Trading Card Game, the Egg Mobile appears in a collectible card set. It is incorrectly referred to as the "Egg Hornet".
Sonic Boom (TV Series):
The Egg Mobile will return in the Sonic Boom series, using a similar design to its Sonic 4 appearance, though it not has no seat to sit in, (resulting in the doctor having to stand up), and there is no backside. The two engines on the back are now on the sides, though they still point backwards, and the hazard stripes are replaced with orange strips resembling the reflectors on a bicycle. The windshield is now pink instead of clear and has a yellow band at the bottom with some black tint along the sides. The headlight on the front is now a set of three blue LED bulbs and the miniature airplane wings are missing. The bottom engine is missing and the two engines that remain have vents on the front. A pair of small headlights is also present on either side of the front.
- The alternate spelling "Eggmobile" originated from a track title called "ENEMY:Eggmobile2&3" from the Sonic Adventure sound test, but it has been used as late as Sonic Lost World when the game is set to other languages besides English and Japanese.
- The Eggman Mobile is also referred to as "Eggman's mobile" in the Japanese Sonic the Hedgehog 2 manual.
- The Egg Mobile is not seen featured as part of boss vehicles in Sonic Rivals, even through Eggman Nega somehow manages to escape from the arena.
- During many CGI cutscenes of Sonic Unleashed, Eggman has a Sega Dreamcast lying in the pilot seat of the Egg Mobile's cockpit. There are also two Dreamcast games to be seen, one including the modified Sonic Adventure cover featuring Eggman instead of Sonic and the second game's cover shows artwork of another Sonic Team game Nights: Journey of Dreams.
- In Sonic Unleashed and later games, the Egg Mobile has a main button with seven lights on the sides which each have the colors of the Chaos Emeralds.
- The Egg Mobile has a striking resemblance to the Wily Capsule from the Mega Man series.
