Second Robotnik War

The Second Robotnik War is 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 war ended abruptly 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.

Prelude to War: The Giant Borg
As the ongoing conflict between Sonic Prime and Robo-Robotnik, the Second Robotnik War began when Robo-Robotnik came to Mobius Prime with his army of Shadowbots to destroy the various versions of Sonic the Hedgehog assembled there, including his own nemesis Cyborg Sonic. They were then defeated by Robotnik Prime's SWATbots, leading Robo-Robotnik to seek out the Giant Borg battlesuit by enlisting the aid of Evil Sonic. Despite the power of the weapon, it-and Robo-Robotnik-were split into pieces by the efforts of some 1000 different versions of Sonic. Robo-Robotnik managed to survive by transferring his consciousness to a space station in an alternate zone where he was left helpless until Robotnik Prime was inadvertently transported there by E.V.E.. Inspired by his counterpart's visit and words of defiance to Robo-Robotnik's fatalistic attitude, Robo-Robotnik returned him home, but not before learning of Giant Borg's dispersal. Retrieving the piece located in his zone, he created a new body for himself and destroyed that version of Mobius with a nuclear bombardment. Robo-Robotnik then attempted to resume the war by recreating Giant Borg, but simply transported himself to Mobius Prime when this failed. (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. His new body and the satellites were then destroyed, though not before he managed to transport most of the Robians to new labor locations. (StH: #62, #64, #67, #68, #70, #71, #72, #73, #74, #75)

All Out War
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 was also drawn into the conflict as Eggman invaded and smashed the Master Emerald in order to make Chaos stronger. Eggman actually came to Station Square's aid 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 Acorn Kingdom 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)

Mobian Victory and Aftermath: The Iron Dominion
Following Dr. Eggman's defeat by Sonic the Hedgehog which resulted in the loss of his sanity, Snively invited Regina F 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 capitol 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.
