Doctor Robotnik

Dr. Robotnik began his existence as Julian Kintobor of the House of Ivo, born in the city of Megapolis. He studied under the genius scientist, Dr. Nate Morgan for an extended period of time. Once his mentor passed unto him everything he knew, Julian conspired against Morgan and had him banished.

During the breakout of the Great War between the animal-like Mobians and humanoid Overlanders, Julian worked as a high-profile weapons engineer for the Overlander armies, brainstorming the most sophisticated military hardware in history. However, Julian's methods were put into question when it was revealed that he utilized live Overlander test subjects to perfect his weaponry. He was tried in court by the Minister of Justice, Colin Kintobor (his brother), and sentenced to ten years of imprisonment.

Sometime after his arrest, Julian somehow escaped confinement. After barely evading a death squad sent after him, Julian made it to the Badlands and found himself rescued by Jules and Sir Charles. The brothers brought him to the Kingdom of Acorn, where he was welcomed. In gratitude, Julian swore allegiance to King Acorn and pledged to impart inside knowledge on the Overlanders to turn the tide of the war. In addition to the Royal Family, a titled "Warlord" was charged with overseeing military matters. The Warlord at the time of Julian's arrival was a scheming lion named Kodos, who tried to take Julian under his wing in a plot to overthrow King Maximillian and rule. Kodos planned to stage a coup and send his enemies, such as King Maximillian, to the Zone of Silence. Julian liked the idea of conquering the Kingdom, but decided he didn't want to share power. Instead he tricked Kodos and banished him to Zone of Silence. Following Kodos' "disappearance", Julian assumed the mantle of Warlord.

The discovery of Sir Charles' invention - the Roboticizer - played an integral part of his schemes. At first believing it to be a threat to his plans, Julian then realized it could be used to his advantage. After secretly sabotaging the device so that those roboticized would become mindless drones that obeyed only his commands, Jules Hedgehog became his first victim.

Following this, Julian arranged for both the Overlord and King Max to decide the outcome of the Great War over a sword duel. In reality, the duel was designed to make Julian's plans of global domination easier, with at least one of his enemies supposed to die in the fight. If the Overlord won, Julian planned on simply taking command of the Mobians and leading them to a never-ending war. If King Max won, the Overlord would be killed and the Overlanders would surrender, removing a major power and enabling Julian to take over the Kingdom of Acorn from within. When King Max won the fight but decided not to slay the Overlord, Julian at first believed his plans to be foiled. However, Sir Charles, still blaming himself for what happened to his brother and sister-in-law, turned over the Roboticizer to Julian, which he realized he could use to enslave the Mobians.

Not long afterwards when Bernie discovered Jules being used as a pawn, Julian had the Robian throw her into the roboticizer as well. Julian explained to the already grieving Sir Charles that Bernie was roboticized in a lab accident while she tampered with the roboticizer. As a result of these losses, Sir Charles left the field of sciense to raise his nephew, while Julian's treachery went undetected.

Not long after the Great War's end, King Max agreed to Julian's plans to "dismantle" the military, also ending his title as Warlord and promiting him to the Minister of Science, all of which would be presented at a victory ceremony. Before the ceremony took place, Julian's plans to overthrow the kingdom were discovered by Amadeus Prower on the day of his son's birth. However, he too was subjected to the roboticizer before he could warn anyone. Following this, Julian gave his nephew Snively the order to begin the attack. The various hordes of SWATbots struck various points simultaniously throughout Mobotropolis, virtually halting any resistance, while also rounding up the citizens for roboticization. Changing his name from Julian Kintobor to Dr. Ivo Robotnik, he transfigured the once beautiful capital city of Mobotropolis into an industrial wasteland he dubbed Robotropolis. Robotnik's most symbolic victory was exiling King Maximillian Acorn into the Zone of Silence, securing his position as ruler of the city.

Shortly after his capturing of Mobotropolis, Robotnik found himself facing a resistance force known as the Freedom Fighters. The group used guerilla warfare, sabotage and hit-and-run tactics to disrupt Robotnik's rule, raiding his factories for supplies and destroying them to prevent them from being used again. Over time, the Original Freedom Fighters proved quite successful in damaging Robotnik's infrastructure. However, after promising one of their members, Private Trey Scales, power and wealth, Robotnik managed to lure the whole group into a trap, roboticizing them and sending them into the Zone of Silence. This quelled local resistance until the rise of the Knothole Freedom Fighters.

Following this success, the tyrant then focused his attention on consolidating the rest of the planet. Soon enough, he had nearly all of inhabited Mobius under his thumb; only a selected few managed to hide from his expanding reach. He would continue to rule Mobius with an iron fist, with his loyal robotic henchmen and his wayward nephew, Snively. As time went on, Robotnik disseminated various regional governors across the planet called "Sub-Bosses" to enforce his will and to lead campaigns against local rebels, such as the High Sheriff in the former Kingdom of Mercia, who successfully crushed the Crazy Kritter Freedom Fighters, and Crocbot in Downunda, who managed to enslave much of the local population.

Sonic the Hedgehog was a long-time enemy of Robotnik during his reign. As a child, Sonic had encountered Robotnik before, while he was still Warlord - a young Sonic used to play with Princess Sally in the palace, since his father and uncle were officers of the King. After Robotnik took power, a young Princess Sally and the rest of the future Freedom Fighters were taken (as children) out of Mobotropolis and hidden by their elders in the Great Forest.

Sonic took an immediate dislike to the belligerent Robotnik. Sonic's Uncle Chuck, who operated a chili dog stand and raised Sonic like a son, was eventually captured by Robotnik's SWATbots and roboticized. Sonic recklessly tried to break Chuck out of Robotropolis all by himself, but once he saw that Chuck was a mindless robot, Sonic realized he could not help him. Inspired by the original Freedom Fighters, Sonic and Sally formed their own rebel group after the original's demise, known as the Knothole Freedom Fighters.

Robotnik would launch several plots to destroy the Freedom Fighters - especially Sonic - particularly in his last year of power. These plots included using the robotic-plant Krudzu to spread and destroy the Great Forest, creating the "Versatile Evolvanoid" E.V.E. to destoy Sonic, the use of the Weather Annihilator to flush out any resistance, using an amnesia-ridden Sonic to defeat the Freedom Fighters, the use of Combots to locate Knothole, and sending supplies to Crocbot in Downunda to quell the local Freedom Fighter cell. All of these attempts proved futile however.

At one point, Robotnik nearly managed to achieve victory over Sonic and the Knothole Freedom Fighters. With the help of escaped convict Nack the Weasel, Robotnik managed to capture and roboticize his nemesis, making him the powerful and subservient Mecha Sonic. While Mecha Sonic managed to destroy a large portion of Knothole Village, he was prevented from providing its location when Mecha Knuckles attacked him. Ultimately Robotnik's plan backfired when the two Robians collided into Robotropolis, turning it into nuclear slag. Sonic was restored to his organic self shortly afterwards by his One Billionth Power Ring, while Knuckles used the de-roboticizer.

Following the Mecha Sonic disaster, Robotnik set to work on his next big scheme - the Death Egg; a powerful, orbital battle station capable of roboticizing the entire planet. Robotnik boarded his vessel upon its completion, leaving the rebuilding of Robotropolis to his nephew Snively, who instead used the SWATbot labour force to pamper him. Although nearly successful in sinking the Floating Island, the Death Egg was ultimtely destroyed by Sonic and Tails.

After suffering numerous setbacks and having all of his plans foiled, Robotnik was furious. He finally developed his ultimate scheme, Operation: EndGame.

Operation: EndGame entailed several phases. Firstly, Robotnik tried to have Sally killed and frame Sonic for her murder, with help from the traitor Drago Wolf. Robotnik would also infiltrate Knothole using a robot clone of King Acorn. With Knothole's location now known, Robotnik arrived at the Freedom Fighters' doorstep and held them at gunpoint. Rather than kill all of them immediately, Robotnik decided to make his victory more symbolic by using Knothole as a testing ground for his new "Ultimate Annihilator", a satellite weapon capable of warping reality and erasing matter. However, his plan began to unravel when Drago was discovered to be a traitor and Sonic was no longer charged with Sally's murder. Sonic went to fight Robotnik face to face to avenge Sally, but Robotnik managed to fire the Ultimate Annihilator anyways. However, unbeknownst to him, Snively had altered to weapon's programming to only target him, which would allow Snively to take over. Robotnik was subsequently erased by his own weapons during his battle with Sonic.

Due to Chaos Knuckles' tampering with time, various versions of Dr. Ivo Robotnik appeared in different scenarios. In one, Robotnik had Sonic and Sally cornered on the edge of a building and demanded they return his "Flora Terminus file". Sonic and Sally jumped off the building and landed in the Freedom Fighter Special and escaped. The timeline then changed again and was eventually restored by Chaos Knuckles.

Robotnik's displaced molecules recombined with the help of Chaos Knuckles' reality-warping abilities and a device invented by Dr. Eggman. The reborn Robotnik soon formulated a plot with Eggman to reverse the process as a way to destroy Sonic and his comrades. Robotnik tricked his former enemies in Knothole Village into thinking Eggman had resurrected him in order to steal his memories, and that he had escaped in hopes of forging an alliance with Sonic. King Acorn goes along with the scheme, but it is revealed that the Freedom Fighters only granted him amnesty in an attempt to sabotage the device that had brought him back. Robotnik's return is cut short during a quarrel with Eggman. He finds out that a machine is holding his presence in the prime dimension. With the machine destroyed, Robotnik's atoms remained dispersed forever.
