The Second Robotnik War also known the Eggman War was the conflict between the Eggman Empire and the allied forces of the Kingdom of Acorn, United Federation, and other nations in various regions of Mobius. It takes its name from Dr. Eggman, who replaced Dr. Ivo Robotnik as ruler of the empire following his predecessor's defeat at the end of the First Robotnik War. The allied forces temporarily won victory after Dr. Eggman fell into madness following a defeat at the hands of Sonic the Hedgehog. However, conflict began once again as the Iron Dominion simply usurped parts of the Eggman Empire into its territory and continued the war against the Freedom Fighters although Eggman escaped at the Iron Dominion's defeat. He soon regained control of his forces and launched the newest Death Egg on a rampage around the planet.


Prelude to War: The Giant Borg[]

The seeds for the Second Robotnik War were planted during a chance encounter between Robotnik Prime and his counterpart, from an alternate-universe, Robo-Robotnik. Although Robo-Robotnik had been defeated by his version of Sonic the Hedgehog, with only his digital consciousness remaining on a derelict space station, Robotnik Prime convinced him not to give up and to transport him back to Mobius Prime. Upon doing this, Robo-Robotnik probed the mind of his counterpart and learned about the Giant Borg, which had been used to nearly defeat an army of Sonics from across the multi-verse by another Robo-Robotnik. When he discovered that a piece of the Giant Borg was located in his zone, he retrieved it and created a new body for himself. He then proceeded to destroy his universe's Mobotropolis, including the Royal Family. Following this he discovered that Robotnik Prime had been killed, and with his arch enemy now dead, he decided to travel to Mobius Prime to fill the void in both his life and Sonic Prime's. He briefly attempted to recreate the Giant Borg by using Evil Sonic to gather its pieces, but when it ended up in the hands of another Dr. Robotnik he simply transported himself to Mobius Prime. (StH: #19, #22, #75, SSS: #10)

Cold War from the Satellites[]

Robo-Robotnik proceeded to conspire from the shadows for several months onboard a group of satellites he brought with him from his own zone. He used each satellite to cause a series of events on the planet surface, first to open the jail cells in the Devil's Gulag prison to release the Snively, the Fearsome Foursome, Drago Wolf and Sleuth "Doggy" Dawg, then to cause an avalanche in the Southern Tundra, which nearly buried Sonic and Tails. Following this he activated a series of traps and robots by the Lost Temple of Shazamazon, restored Kodos and Uma Arachnis to their organic selves, hurled a series of meteorites at Mobotropolis, activated a giant Mutate which attacked and captured Snively, fired a time beam at Knothole which could have destroyed all time, and presented a autobiography on the life of Dr. Robotnik over King Max's speech. Last of all, he captured the Robians from Knothole to use as his personal slave force, and finally encountered the Knothole Freedom Fighters again when they came to stop him. He briefly masqueraded as the original Robotnik, who had perished recently, before being exposed for his true self. (StH: #62, #64, #67, #68, #70, #71, #72, #73, #74, #75)

All Out War[]


Shadowbots capture Mobotropolis' citizens during the reinvasion.

By the time Robo-Robotnik's deception had been found out, the Knothole Freedom Fighters had been lured away from Mobotropolis and into space while a massive army of Delta and Gamma model Shadowbots invaded the city and successfully recaptured it along with many of its inhabitants. His new body and space station were then destroyed, though not before he managed to transport most of the Robians to new labor locations. Robo-Robotnik survived yet again by transferring himself to a new robotic body, after which he took on the guise of Dr. Eggman or simply Dr. Robotnik. The Freedom Fighters quickly struck against him, implanting a virus that prevented him from remembering Knothole's location so that he would be unable to attack it. This was followed by the first encounter either side of the war had with Station Square, which was threatened by Eggman's awakening of the Chaos creature. Angel Island and Echidnaopolis were also drawn into the conflict as Eggman invaded the Chaos Chamber and smashed the Master Emerald in order to make Chaos stronger. Eggman's attempt to conquer the Hidden City of the Ancients came to an abrupt end after Perfect Chaos betrayed him, but following the creature's defeat he went back to attacking them. Silver Sonic's attack proved ineffective, and the robot was reprogrammed to serve as a protector for the city. (StH: #75, #76, #77, #78, #79, #83, #84, #85)

Dr. Eggman then captured Prince Elias Acorn, resulting in a massive effort by the Royal Army to rescue him. He then managed to acquire the journal of his grandfather, Gerald Robotnik, which led to Shadow the Hedgehog's entrance into the war. (StH: #88, #89, #98)

Advances of the Eggman Empire[]

During Sonic's year-long absence in space, Dr. Eggman took advantage of this and drastically changed his campaign tactics. After reasserting control of all his territories under the banner of his official Eggman Empire, he declared open warfare on the Kingdom of Knothole, the Republic of Station Square and their allies. One of his most significant moves was the all-out invasion of Angel Island with the assistance of his newly sponsored Dingo Regime under Kage Von Stryker, during which the Brotherhood of Guardians disappeared (thanks to Dr. Finitevus), the Dark Legion became a resistance group, and over time resulted in the deaths of over 90% of the Echidna population. (StH: #130, #131, #132, #133, #134, #138, #139, #181)


Robotnik's forces march towards Fort Acorn.

When Sonic finally returned, Eggman realized he had to raise the stakes and initiated Operation: Triple Threat, a three-pronged assault meant to wipe out both the Kingdom of Knothole and Republic of Station Square in one blow by nuclear means. The plan was foiled due to both nations' combined efforts, however the victory was short lived when it was learned that Golden Hive Colony had been overrun with few known survivors. After Sonic lead a rescue mission to Angel Island liberate the captured Locke and defend the Master Emerald from Eggman's agent Hunter, the war began to stagnate again with neither side making any serious advances toward gaining the upper hand. The status-quo lasted for a while, but things began to change rapidly when a new figure named "Anonymous," who was hostile towards both sides, entered the war shortly before Sonic's next birthday. (StH: #130, #131, #132, #133, #134, #138, #139, #140, #141, #146, #147, #148, #149, #153, #154, #160)

For a while, "Anonymous" operated in a manner that made his motives obscure. He first attempted to get an Auto Automaton version of Tommy Turtle close to Sonic to be assassinated while sending Dr. Eggman a faked video of the Destructix getting roboticized (a technology now lost to him). He next unleashed a swarm of Eggman's nanites that began destroying the Great Forest while configuring themselves into a massive city. Some time later, "Anonymous" also commandeered Knothole's army of Metal Sonic Troopers, sent Eggman a delayed death threat, and hacked Mecha so Robotnik would have no way to defend himself, but then set them upon Knothole once he escaped. Afterwards, a complicated operation took place which culminated in using the Arachne and Sword of Acorns to release Ixis Naugus from the Zone of Silence which would kill the Ancient Walkers and release Mammoth Mogul from captivity in his Chaos Emerald. This would then lead to their capture by Dr. Eggman as fuel sources in his Egg Grape Chambers. "Anonymous" was finally revealed to be A.D.A.M., Eggman's computer virus "son", when he released Mogul in exchange for his Chaos Emerald so that he could start the Great Harmony and collect all the Chaos Emeralds in the galaxy. While this goal was achieved, the Emeralds were sent into the Zone of Silence, turning it into the Special Zone, and Tommy Turtle sacrificed himself to the Egg Fleet to stop A.D.A.M., despite Super Sonic's efforts. (StH: #135, #152, #157, #158, #159, #162, #163, #164, #168, #169, #170)

Another upset came in the form of Shadow the Hedgehog defecting from the Eggman Empire. Though he had joined with Robotnik in the aftermath of the Metal Sonic Trooper attack, Shadow became increasingly impatient and frustrated at not being given answers as to his true identity or purpose. Shadow finally had enough, stole Professor Gerald's video diary after threatening Snively and Eggman, and after receiving aid from Freedom HQ in viewing it, decided to answer what he felt was his calling to protect Mobius by joining G.U.N. in the United Federation. (StH: #171)


Eggman prepares to destroy Knothole.

Tired of suffering numerous setbacks and betrayals by his underlings and creations, Dr. Eggman decided enough was enough and prepared to put an end to the "war games" he had put his adversaries through in one fell swoop. With the Egg Fleet nearing completion, Robotnik began drawing up battle plans to decimate the main focal point of resistance to his empire- the Kingdom of Knothole. With his new Egg Beater battlesuit finished, Eggman lead his Egg Fleet in an all-out assault on Knothole, capturing all but a few of its civilians. The victory was short lived however, as Sonic lead a breakout that resulted in everyone being sent safely to the nanite city, now reconverted into New Mobotropolis, the destruction of the Egg Beater and the Egg Fleet's total firepower being rendered useless and successfully repelled. (StH: #173, #174, #175, #176, #177)

Turning the Tides[]

Following the rampage of Enerjak, the bulk of the Eggman Empire's military forces were completely obliterated. However, an alliance formed between the Eggman Empire and the Dark Legion (rechristened the "Dark Egg Legion") provided the now-crippled Eggman Empire with some degree of combat capability. This proved futile however as the Freedom Fighters and Chaotix engaged in an offensive campaign that led to defeat after defeat with Dr. Eggman becoming increasingly frustrated and enraged, signs of increased psychological instability becoming evident as time went on. This became evident when Eggman built and attempted to deploy a last-ditch weapon of mass destruction that if fired would not only have resulted in the annihilation of his enemies, but the destruction of a significant portion of the Eggdome as well. Before this weapon could be used however, it was destroyed by the combined efforts of Sonic, Shadow, and Rouge the Bat. (StH: #183, #184, #189, #190, #194, SU: #2)

Rise and Fall of the Iron Dominion[]

Ultimately, the remainder of the Eggman Empire's defenses were breached and the Freedom Fighters and Chaotix made their way into the Eggdome. Upon entry, they discovered that Dr. Egman had barricaded himself inside the heart of the complex, with only an opening small enough for Sonic to get through using his spin-dash maneuver. The hedgehog then confronted Dr. Eggman in his Egg Tarantula for a one on one in a final showdown between the two mortal enemies. After a pitched battle, the dictator was finally defeated, and his remaining sanity utterly shattered. (StH: #198, #199, #200)


New Mobotropolis populace celebrate at believing they have won the war.

With Dr. Eggman's defeat by Sonic and the loss of his sanity, Snively invited the Iron Queen Regina Ferrum and her followers to rule the Eggman Empire with him. The Iron Dominion then assumed primary control over the Eggman Empire and continues hostilties with the Republic of Acorn and its allies, including an incursion into the capital city of New Mobotropolis by the Iron Queen and Snively Robotnik wherein the former used her Magitek powers to override first Bunnie D'Coolette and then Monkey Khan and turn them against the city's inhabitants. (StH: #200, #201, #202, #203, #204)

Subsequent skirmishes between the two powers resulted in a series of victories for the Republic of Acorn, one of which led to Dr. Eggman being taken into custody by the Republic of Acorn following his escape from the Eggdome and subsequent discovery and capture by Sonic the Hedgehog and Miles "Tails" Prower. (StH: #205, #206)

Any progress made by the Republic of Acorn in the conflict appears to have been compomised as the Iron Queen has recently managed to gain control over NICOLE and by extension the nanites that compose New Mobotropolis itself, giving the Iron Dominion a significant strategic advantage and placing the future of the Republic of Acorn in serious jeopardy. (StH: #208)

However, the Iron Dominion soon lost all of its forces, the Iron King was blown away by the Fan of Fen Xing, and the Iron Queen was arrested. Due to several heroes being distracted by this, Dr. Eggman (who had regained his sanity) and Snively escaped to New Megaopolis. (StH: #211)

Fighting the Grandmasters[]

Afterwards, Eggman, Snively, and the Echidna Dark Egg Legion went into hiding whilst elsewhere the Battle Bird Armada and other Dark Egg Legion chapters started making conflict with the various Freedom Fighter groups, the Felidae, the Walrus Herd, and the new Wolf Pack Nation. Notable amongst the projects undertaken by the Legion was the construction of gigantic refueling stations, including the Oil Ocean Refinery near Sand Blast City, in preparation for the launch of a massive air vehicle. (StH: #213, #214, #215, #216, #217, #218, SU: #17, #18)

Despite the Dominion's defeat, the Iron Queen's temporary control on the electronic lynx had left a serious "psychological" scar in the city. NICOLE began noticing some of the citizens growing uneasy of her. Even she feared that she may lose control again. Mina, who was especially traumatized from the attack, was inspired by her boyfriend Ash to express her current feelings in song and inspire change to the community. Her band proceeded to set up a concert for just that purpose. (StH: #215, #219, #220)

War with Eggman Resumes[]

As Sonic and the Freedom Fighters dealt with Geoffrey St. John's betrayal and Ixis Naugus's ascension to the throne, Dr. Eggman made his grand return, revealing the Egg Dome to be the Death Egg Mark 2. Naugus and the Freedom Fighters put aside their differences temporarily to take down Eggman and the Death Egg. However, the battle was disastrous: after the failure of the first Genesis Wave, Sally sacrificed herself to prevent Eggman from using the World Roboticizer on Mobius, turning her into Mecha Sally. With the Death Egg Mark 2 damaged, Eggman disappeared and began a number of attacks as he tried to repair his battlestation. (StH #224, 225, 230, 231)

His subsequent attacks would ravage the Freedom Fighters even more - an attack by Titan Metal Sonic would end with Bunnie "Rabbot" D'Coolette's robotic parts accidentally crystalized, then restored to normal, by Naugus. An ambush by the Metal Series on the evacuating Acorn family would lead to Antoine D'Coolette to be grievously wounded. (StH 231, 234)

Despite these setbacks, the remains of the Freedom Fighters would spawn two groups, Team Freedom and Team Fighters, with Team Fighters chasing after Eggman. After a long and hard chase, the team, plus Silver the Hedgehog, confronted Eggman in the Northern Tundra. Mecha Sally was rescued, however, Eggman countered this victory by unleashing the Second Genesis Wave. (StH 235, 247)
