Dr. Ivo Robotnik

Dr. Ivo Robotnik was formerly known as Julian Kintobor, a brilliant scientist within the Overlander community before becoming the ruler of Mobius. He escaped imprisonment and offered his services to King Maximillian Acorn. He enables the Mobians to defeat the Overlanders during the Great War, only to take over the kingdom five years later, ruling as a despot dictator for ten years. He was killed in a battle with Sonic the Hedgehog during Operation: Endgame.

Early Life
Dr. Robotnik began his existence as Julian Kintobor of the House of Ivo, born in the city of New Megopolis ("Kintobor" is Robotnik spelled backwards). 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. Due to his engineering prowess, the Overlanders nearly pushed their Mobian adversaries to the brink of defeat. 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 10 years of imprisonment. Sometime after his arrest, Julian somehow escaped confinement. (StH: #50)

Warlord of the Kingdom of Acorn
After barely evading a death squad sent after him, Julian made it to the Mobian border and found himself rescued by Sonic's father Jules Hedgehog and uncle Sir Charles (aka Uncle Chuck). Both hedgehogs 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. (StH: #50, #72)

Betrayal and Rise to Power
After defeating the Overlanders in the Great War, Warlord Julian used Charles' invention, the Roboticizer, to his own twisted ends. After sabotaging it to turn Charles' brother (and Sonic's father) Jules into a drone, he secretly had Sonic's mother, Bernie, roboticized as well. Bernie's roboticization was blamed on a lab accident, and soon Tails' father Amadeus was likewise turned into a robot. Julian's plotting culminated with a successful coup to overthrow the kingdom, using the 'dismantled' fleet of warships and an army of robotic troopers to take over. Changing his name from Julian Kintobor to 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. (StH: #43, #78, #79)

Once his power was secure, 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 select 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 "Underbosses" to enforce his will and to lead campaigns against local rebels. (TMS: #1, #2, #3)

A Worthy Adversary
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. (StH: #120, #142, #143)

Sonic takes an immediate dislike to the belligerent Robotnik, foiling several of the evildoer's plans before he is even a teen. Sonic's Uncle Chuck, who operated a chili dog stand and raised Sonic like a son, is eventually captured by Robotnik's SWATbots and robotcized. Sonic recklessly tries to break Chuck out of Robotropolis all by himself, but once he sees that Chuck is a mindless robot, Sonic realizes he cannot help him. Instead, Sonic joins forces with Princess Sally Acorn and her friends, who will grow up to become the Freedom Fighters). The underground resistance grows until their base of operations, Knothole Village, is established (hidden deep in the same forest where the Mobians had fled); The discovery and extermination of this secret headquarters is Robotnik's primary goal. (SSS: #5)

Championed by Sonic, the Freedom Fighters become s a real threat to Robotnik's reign. He continually attempts to crush the resistance for months, until he enacted Operation: EndGame, where he tried to have Sally killed and frame Sonic for her murder. Robotnik also infiltrated the rebel base 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. Sonic attacks Robotnik as the Ultimate Annihilator backfires, tearing the sparring adversaries apart atom by atom. Unfortunately for Robotnik, Snively tampered with the Annihilator and programmed it to only affect him; while Sonic and Knothole emerge unscathed, Robotnik remains vaporized by his weapon. (StH: #47, #48, #49, #50)

Beyond the Grave
Robotnik's displaced molecules recombined with the help of Knuckles' reality-warping abilities and a device invented by Dr. Eggman. The reborn Robotnik soon formulates a plot with Eggman to reverse the process as a way to destroy Sonic and his comrades. Robotnik tricks 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 remain dispersed forever. (StH: #108)

Abilities
Robotnik's high intellect made him a formidable foe on all levels. Despite the fact his schemes were often foiled by the Freedom Fighters, Robotnik was able to successfully win the Great War, overthrow the Kingdom of Acorn, and rule for over a decade. In addition to his intelligence, Robotnik's roboticized left arm enabled him to fire rockets and lasers.

Background Information
Recent developments in the comic have revealed a new villain tentatively titled "Anonymous" who manipulates events behind the scenes using older Robotnik technology. It has been stated that he is around Robotnik's height, and his silhouette looks markedly like Robotnik Prime. In a surprise twist however, it was revealed that Anonymous is A.D.A.M., Robo-Robotnik's rogue sentient computer virus. The lead writer has since explained that the reason Robotnik Prime's image was used to depict Anonymous in past issues was due to the fact that he was in fact originally going to turn out to be the original Robotnik.
