The Egg Mobile

The Egg Mobile is a one-person, multi-purpose hovercraft used by Dr. Ivo Robotnik, and later his alternate-future counterpart Dr. Eggman as a personal means of transportation and attack craft. The Egg Mobile can be fitted with a wide array of weapons and also serves as the cockpit for larger machines, as well as an escape pod when they are inevitably defeated by Sonic the Hedgehog and/or his allies.

The Egg Mobile was originally used by Dr. Ivo Robotnik as a means of transportation and to attack Sonic and the Knothole Freedom Fighters, fitted with a wide variety of weapons including lasers, wrecking balls, flame throwers, and even a cannon designed to fire mega muck. A few early models of it were seen in use by Robotnik during the Great War when he captured the villagers of Leung West and also attempted to take over Megapolis. After his initial invasion of Mobotropolis, Robotnik then entered the Zone of Silence to analyze its properties, thinking he had come prepared with his Egg Mobile, only for it to suddenly be destroyed by Feist who then brought him before Ixis Naugus. Robotnik used his technical prowess to patch together an escape vehicle from the Egg Mobile's remains and was then able to flee the zone with Snively's help.

Afterwards, Robotnik used the Egg Mobile infrequently at best, either for occasionally going after Sonic personally and ambushing him in zones, or for making a hasty retreat from larger threats like the Universalamander. One of its most noted uses was when Snively donned a Robotnik disguise and then flew behind Sonic at a distance in the Collision Chaos Zone, using the Egg Mobile to burn up the race track behind him. Robotnik also used an Egg Mobile to transport himself to the Death Egg once the airship became operational. During Operation: EndGame, a SWATbot patrol attacked a transport carrying Sonic and Sleuth Dawg to the Devil's Gulag, some of the SWATbots piloting Egg Mobiles. This is the only time during Robotnik's reign the Egg Mobile was shown having a non-biological pilot.

Once he recaptured Mobotropolis, Dr. Eggman piloted an Egg Mobile as he lead his Shadowbots in an attack on Angel Island to steal the Master Emerald and revive Chaos. He continued to use it as his personal means of transportation as he confronted Sonic, Knuckles, and Tails repeatedly, and also used it to escape his Egg Carrier once it went down. As time went on the Egg Mobile fell into disuse, however it began reappearing after Robotnik and Snively used them to flee and get an aerial view of Enerjak’s destruction of New Megaopolis, the Badnik Horde, and the Egg Fleet.

When the Dark Legion was integrated into the Dark Egg Legion’s New Megaopolis branch, they were issued out to various troopers and field leaders with a heavily overhauled design and most of them stored in the troop barracks of the Eggdome for easy deployment. Eggman himself continued to use the Egg Mobile as well, in particular as the control module and escape vehicle of his Egg Phoenix. They were also used following Eggman’s breakdown, by the Iron Queen and Snively during their incursion into New Mobotropolis where Snively used his to destroy Monkey Khan’s Power Ring crown and later on when the two led the massed forces of the Iron Dominion in pursuit of Dr. Eggman after his escape from the Eggdome (wherein it was called a "flying pod" by the two).

After Dr. Eggman resumed control of operations and had the Eggdome repaired, he and Snively went on a mission to the Special Zone in their Egg Mobiles to retrieve a Chaos Emerald. There they encountered Feist, who challenged them to race each other over an Emerald which they readily agreed to. Though it appeared Snively would win due to Robotnik’s weight slowing down his Egg Mobile, the doctor cheated and shot out Snively’s pod from behind with a small missile launcher built into his own. After seemingly leaving Snively with Feist, Eggman activated a teleportation device in Snively’s Egg Mobile which beamed him and his pod out of the Special Zone and back into the Eggdome. Eggman then went to a core chamber with his pod and put the Emerald in place, flying back to the command deck afterwards.

When Eggman revealed his Death Egg Mark 2, his newly-redesigned Egg Mobile was used as his seat on the bridge of the new airborne battle station. Following the global reset by Eggman, Sonic and the Freedom Fighters had several encounters with Eggman and Snively, who were piloting versions of the Egg Mobile more reminiscent of the original model used by Dr. Robotnik shortly following his rise to power, each armed with a variety of unique weapons. After Super Sonic restored reality to normal, Eggman was once again in his Egg Mobile and armed with several weapons ranging from the deadly to the ridiculous in an attempt to track down Sally, until Sonic destroyed it in his usual fashion. Following the conclusion of Operation: Clean Sweep, Eggman was next seen piloting the Egg Mobile when his forces attacked Stormtop Village while pursing Snively. His robotic assistants Orbot & Cubot also had their own smaller Egg Mobile craft.
