Ivo Robotnik's coup d'état (Sonic Override)

Ivo Robotnik's coup d'état was an event that took place in the Kingdom of Acorn where Dr. Ivo Robotnik took over the whole kingdom, from which he launched his campaign to conquer the rest of Mobius. This would lead to his eventual conflict with Sonic the Hedgehog and the Knothole Freedom Fighters.
== History ==
=== Planning and Action ===
The planning for the coup had begun years before it actually occured. Dr. Ivo Robotnik had been appointed as an assistant to Kodos Lion due to Robotnik's lies about the United Federation planning to attack. Kodos Lion, who was planning on overthrowing King Nigel Acorn, invited Ivo to join him. However, Robotnik, who was there to overthrow King Nigel Acorn on his own, secretly threw Kodos Lion into the Special Zone with help from Walter Nagaus, the court magician. Following Kodos' "disappearance", Robotnik was appointed to the title of Warlord and Court Scientist. From there, Robotnik used his position of power to cause the Great War, making both sides believe the other was hostile towards them.
As Robotnik manipulated world events, Julian "Snively" Robotnik later joined him in his bid to rule Mobius. While the Great War was ongoing, Robotnik started work on the Death Egg, planning to use it in the eventual coup.
Robotnik, needing an army to overthrow the Kingdom of Acorn, raided the neutral village of Kar Leung and forced all of them to undergo an early form of Legionization/Cyberization, which wound up killing all but one of the victims of the raid. The survivor, Ken Khan, then rebelled against Robotnik for killing his entire village, leading to Ken being locked in stasis for 7 years. 
Prior to the Great War's end, Robotnik discovered the Roboticizer, an invention by Sir Charles Hedgehog. Feeling this would prove useful in his conquest, Robotnik stole the plans for the Roboticizer.
After the end of the Great War, the Warlord title was dismantled, leaving Ivo the Minister of Science.
=== The Coup ===
Shortly afterwards, King Nigel discovered the Death Egg project and Robotnik's planned betrayal. Robotnik, realizing that he had been discovered, ordered all of his forces to execute the coup plan early. Quickly, Robotnik's forces landed in key points of the Kingdom, such as the Royal Hills Zone, the Star Light Zone, the Spring Yard Zone, the Casino Night Zone, and what would become the Chemical Plant Zone. Soon afterwards, King Nigel Acorn and Walter Nagaus were brought before Dr Ivo Robotnik, where he revealed just what he had planned. Having revealed his betrayal of both Nigel and Walter, Robotnik demonstrated the roboticization process on a few captured Mobians. Following this, he proceeded to banish both into the Special Zone. Having disposed of all his rivals, Robotnik had the SWATBot and Badnik armies round up all the remaining citizens. However, many did manage to escape into the Wood Zone.
=== Aftermath ===
Robotnik's coup had lasting effects on Mobius, and marked the beginning of the Technoric War. Following Robotnik's takeover of Mobotropolis, which he renamed Robotropolis—the capital of the Technoric Empire until Mobtropolis was taken back in early 2193, the tyrant sent out his army to capture other Mobians. Not long after the coup, Robotnik had sent out his armies to many regions of the globe, including Atrika, Downunda, and the Kingdom of Mercia. It would take until 2192 for any major victory against the Technoric Empire would occur, the first one occuring on South Island.
