The Egg Mobile looks virtually identical to the standard, unmodified Egg Mobile.
Features and abilities
The Egg Mobile is capable of flight vertically with great precision.
Sonic the Hedgehog (16-bit)
In Sonic the Hedgehog (16-bit), and its numerous ports and remasters, the Egg Mobile is fought at the end of Labyrinth Zone Act 3. In the original game, it is encountered by Sonic. In the 2013 remaster, it can also be fought with Tails and Knuckles.
This boss fight is perhaps the most unique one in the game, as the player has to climb through a tunnel filled with traps such as moving spears and statues spewing fireballs. Along the way, Dr. Robotnik will fly up in his Egg Mobile attempting to escape, while the water will keep rising.
Unlike the other bosses in the game, the player does not need to hit the boss eight times, although it is possible for them to do so. The Egg Mobile is also completely unmodified and without weaponry. Instead, it is more about surviving, as they have to avoid the various obstacles along the way while trying to escape from the water, which can make their character drown.
- Before the player faces the Egg Mobile, a Shield monitor is seen on left side of the cave, which can be helpful during the chase.
- In the iPod remaster of the original Sonic the Hedgehog, along with the Sonic Origins remake, the water will stop rising at the height of Sonic's feet by the time he reaches the boss' starting platform.

Sonic the Hedgehog 4: Episode I
The encounter of the Egg Mobile is later seen again as a boss in Sonic the Hedgehog 4: Episode I at the end of Lost Labyrinth Zone. At the start of the boss act, the player has to pick up some rings and head to Dr. Eggman who, after laughing, flies away stage right. The route is more wheeling and smoother than before. Like its previous appearance, there are also numerous booby-trapped obstacles like spears, but there are also Badniks as well on the way. Despite the smoother platforming sections, the water once again rises below, while like in original Sonic the Hedgehog, there are no air bubbles on the route, as the player has to pass quickly as possible without drowning. The player is also able to attack the Egg Mobile by doing Homing Attack into it.
After being bounced to the air via a Spring, the player chases Eggman on the linear arena until the second phase of the boss battle starts. Eggman summons two pillars to rise from the ground, enclosing him and the player. Eggman then summons numerous different looking pillars slowly as attempting to crush the player, while the doctor himself flees to the safer place. The player has to head to the same place as well to survive and manage to hit Eggman at the same time. Eggman repeats doing this with different patterns until the player has defeated him, while the player should also memorize patterns and the doctor's movements.
It is possible to hit the Egg Mobile at the beginning of this phase by standing on either end where the pillar rises up from the ground, jump off quickly before getting crushed and then performing a Homing Attack.
After dealing a total of eight hits on the Egg Mobile across both phases, all pillars present are instantly retracted while the Egg Mobile explodes, prompting Eggman to flee with his damaged craft. The player is then allowed to progress to open the Capsule and complete the Zone.
This battle later reappears at E.G.G. Station Zone as a part of the boss rush before the battle against the Death Egg Robot. The chase section is not included, thereby skipping to the second phase of the battle, where the pillars have a new appearance to fit the space-themed aesthetics of the Zone. After four hits, all pillars present are retracted and the player can move to the next boss.
- During the second phase of this boss, the way the block pillars rise from the ground and the way Sonic has to stand on something to reach the Egg Mobile is similar to the Egg Hammer boss of Aquatic Ruin Zone in Sonic the Hedgehog 2.
- The player can also destroy the Egg Mobile during the chase sequence if the player hits it eight times. Defeating the doctor this way will cause him to not continue the battle with the second phase.

- Various Japanese sources have baptized the boss Doctor Eggman (ドクター・エッグマン Dokutā Egguman?). It should be noted, though, that this name was also used for the other bosses in Sonic the Hedgehog.
