This paper craft is the Doctor Eggman (Doctor Ivo Robotnik), a video game character based on the Sonic the Hedgehog series, the paper model was created by Danimpeo. He is an obese scientist with an IQ of 300 who dreams of dominating the world, and his constant plots to create his Eggman Empire are endlessly thwarted by Sonic the Hedgehog, his arch-enemy, and Sonic's friends.
While his plans initially consisted of building up an incredible army by turning animals into robots and using them to dominate the land, Eggman's schemes branched into much more global threats as he built war machines, used nuclear devices to threaten entire nations, and even relied on mythological and ancient creatures bent on destruction to achieve his goals.
Eventually, the villain would go as far as to target the entire universe and cooked up a scheme to control time and space itself. While all these plans end in failure thanks to the continued efforts of Sonic and his friends, the mad doctor is always able to slip away from certain death or arrest and escape at the last moment, making him a constant threat to the universe and a thorn in Sonic's side.
In childhood, the young Robotnik looked up to his grandfather, Professor Gerald Robotnik, and believed him to be a great man, who had done his best to help mankind and was unfairly executed. From this, the good doctor likely viewed the government as corrupt, and in any case, decided to follow in his grandfather's footsteps to become a scientist. But somewhere along the line, he became obsessed with the idea of a world under his rule, and using his unmatched mechanical genius, began his plans. Long before the first Sonic game, Eggman met the hedgehog, and the two became instant rivals. Over the years, he created several deadly creations, and, realizing the hedgehog's determination was as fierce as his own in overcoming them, gained a respect for his adversary. When he accidentally found his grandfather's diary, he was led on an adventure that would show him that his grandfather was perhaps not as innocent as he had thought. Usually Eggman will try to side with a really powerful being that ends in betrayal. Recently, his plans have been increasingly hindered by outside forces, but this has given him chances to show his hatred of things that would threaten the entire human race, and consequently threaten his plans.
Eggman is a short-tempered, loud, pompous and cruel evil genius who is constantly planning to take over the world. However, his plans have always failed thanks to Sonic and his allies. Despite his intelligence, Dr. Eggman is horribly immature, throwing temper tantrums when Sonic throws the proverbial wrench into his plans, and, at times, seems to overlook crucial details in his plans, such as in the opening sequence of Sonic's story in the 2006 video game when he orders his robots to fire on Sonic while he is escaping with Princess Elise, failing to realize that they could possibly injure or kill Elise if they land a direct hit on Sonic. An example of his immaturity is in the ending of Sonic Unleashed, when one of his robots begins to insult him over his constant failures and calls him a loser; Eggman screams "Oh, shut up!!", attempts to kick him only to comically fail, and then chases him through the desert.
Eggman is also very arrogant and narcissistic; possessing an unhealthy and psychotic belief of self entitlement of controlling the world and beyond and constructs countless technological wonders in his own image to fuel his massive ego. He has built immense warships, such as the Death Egg and the Egg Carrier, as well as escape units such as the Eggmobile. In fact, his most famous machine is an Eggmobile with a wrecking ball attached to the bottom, which appears in Green Hill Zone in the first boss level. His plans to create the ultimate utopia, the Eggman Empire, are always in full swing, and he doesn't care where to start it - in the end, he plans for it to encompass all of Earth. His abominable laughter and maniacal declarations contrast his self-professed softer side as a romanticist, feminist, and gentleman. Despite his and Sonic's constant feud, he has secretly developed a begrudging respect for the hedgehog. Although Eggman is a villain, he helps Sonic and co. when the world is at stake - though the reason is always because he knows there would be nothing left for him to conquer if the planet was destroyed.
Eggman has never shown a willingness to do good or help others without it serving his own ends in some shape or form. While displaying a comical disposition later on in the series, he is quite clearly a cruel minded and brutal man who will use any opportunity presented to him to fuel his self-serving desires, even if that means exploiting worldwide catastrophes to obtain power and dominance. From abducting animals and transforming them into robots for his army, to leading large scale attacks on a terrorist level, Eggman's numerous crimes and exploits continuously transition into more destructive ramifications. He never acknowledges the results of his actions such as the pollution from his fortresses and strongholds that poison the surrounding environments or the ruins that are left from his own attacks on various cities and lands. His exploits have led to numerous tragic events, such as Chaos flooding and utterly destroying all of Station Square and Dark Gaia nearly consuming the whole planet.
However, despite his desire for world domination, he does have a human side, and does not appreciate senseless destruction and killing from other individuals and forces who are beyond his control. In Shadow the Hedgehog, he is shown to be disgusted and shocked at the thought that his own grandfather would sacrifice his own people for the sake of research and aid a ruthless alien empire known as the Black Arms. This demontstrates that even if Eggman does not mind causing chaos and destruction, he ultimately knows that their is a line that others should not cross and was afraid his grandfather did so through betraying humanity and aiding a species that wanted to eliminate the human race.
While this seems contradictory towards Eggman's previous exploits of joining forces with other creatures bent on destruction, it seems that he still wishes to paint his grandfather in a positive light as he was his hero in his childhood. This more humane side to the doctor is shown in full force at the end of Sonic Adventure 2, where he has an honest and genuine conversation with Tails about how much he adored his grandfather, questioning the actions of his fallen idol and wondering if he intended to destroy him as well.
Despite this, Eggman seems to have no problem in committing senseless killing and destruction as long as he is the one in control of the forces doing so. It would seem that the doctor is so bent on authority, that he refuses to let other forces destroy his planet unless they are under his complete control. This is shown when Chaos betrays Eggman and floods all of Station Square, a horrendous action that Eggman had planned Chaos to do from the very beginning regardless of the beast's betrayal against him, but refused to allow his rampage to continue as Chaos was no longer under his control and therefore, in Eggman's mind, was beyond any type of control.
As shown in Sonic CD's Bad Futures, the Eggman Empire is little more than a post-apocalyptic ruin, spreading destruction and pollution in every known area of the game. Additionally, in Sonic Adventure, he launched a missile deep into the heart of a heavily populated Station Square to utterly destroy it, even if that meant killing himself, as a twisted form of revenge and victory over Sonic after his plans to use Chaos to dominate the planet through mass destruction failed. In Sonic Adventure 2, his desire for destruction appears at it's height as he laughs insanely at the Eclipse Cannon's impending firing at the planet, which would've had devastating effects to billions of lives, until his grandfather's true operations were activated. He also admits that had he had the chance to use the space colony ARK to collide with Earth, he would've done so a long time ago, showing admiration towards his grandfather's mad projects.
In Sonic Unleashed, there is a possibility, realistically speaking, that he murdered millions when reawakening Dark Gaia by splitting the planet itself apart. However, the effects of the quake in relation to the earth's populace is never touched upon and avoided as a critical plot point within the context of the story. According to his PA announcement in Sonic Colors, his park can be considered a lethal weapon in itself as most of the rides lead to horrifying and agonizing deaths and circumstances should anyone ride them. Lastly, in the beginning of Sonic the Hedgehog, he orders his robots to launch numerous missiles at Sonic with no regard for any that may be caught in the crossfire. Regardless of how many lives may or may not have been lost to Eggman's various schemes, the evil scientist clearly demonstrates a complete disregard for all life, even his own on occasions, as well his own creations, and will go to any means necessary as long as his goals of destroying Sonic and his friends, conquering the planet, and establishing his empire are met with full success.
Eggman also has a tendency to always escape at the last minute, even as all his creations and machines crumble and blow up around him. No matter how close Sonic appears to be finally catching the villain and putting him out of commission, the doctor always has an escape plan, which ironically enough, are the only plans he can formulate that Sonic has been known to fail in foiling. Despite this and his hatred towards Eggman, Sonic has been known at times to spare him and allow Eggman to escape after he has aided him and his friends in saving the planet from other threats such as in Sonic Adventure 2, Sonic Heroes, and Shadow the Hedgehog.
This appears to be indicative of Sonic's hope to see the good in everyone and believes at times that perhaps even Eggman can be redeemed one day after seeing his ability to join forces. However, as time went on, and Eggman's schemes became even more deadly, Sonic lost hope for this belief and his final attacks in the showdowns with the villain became much more aggressive and even posed a threat to the doctor's life, but he still manages to survive and return shortly after, making both individuals nearly impossible to defeat for good and making their battle a never ending one.
Ultimately, while not as openly violent and ruthless as some of his comic book counterparts, Eggman is still a highly brutal and amoral villain with an insatiable lust for power, dominance, and, since meeting Sonic, revenge. His countless plans and operations have left numerous areas, lands, and even planets in ruins and threatened the welfare of not just the entire planet of Earth, but time, space, and the universe itself. While still harboring a more humane side and displaying comical undertones later on in the series, Eggman's ruthless and violent natures can still be seen throughout the series. His uncompromising persistence shared with his appetite for authority and control fuel the conflicts throughout the entire series and guarantee that Sonic will always be needed to stop him.
Eggman's most well known ability is his masterminded plots and schemes which only fail due to Sonic and his friends. He is a remarkable scientist and engineer, as evidenced by the armies of robots he's created. Eggman is an incredibly skilled pilot: able to swoop missiles and lasers in his Eggmobile with skill rivaling that of Tails. Eggman has also shown some considerable physical strength. This is hinted in Sonic Riders, where Eggman could break stone pillars and even statues with just as much ease as Knuckles or Storm, and in Sonic X where he is shown smashing metallic equipment with brute force. Despite his physical structure, Eggman is also very athletic; this is seen in many of the 16-bit era games, where there is almost always a point where Sonic chases him; despite his weight and Sonic's speed, he always manages to outrun his nemesis long enough to reach his next escape vehicle or weapon. This trait of agility is carried on in Mario and Sonic at the Olympic Games and Sega Superstars Tennis. He also has a special sensor in his glasses that allows him to locate Chaos Emeralds. Jokingly, as an in-gameplay mechanic, it is also said that he is faster in running speed than Sonic himself as he always manages to escape his grasp. Although it has been proven, it is unknown if he can consistently outrun Sonic, since he is almost always in his Eggmobile.
