thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist. In developing Eggman, the Sonic Team characterized him as Sonic's opposite. Eggman was designed to represent themes of "machinery" and "development" to play on the then-growing debate between developers and environmentalists and as a symbol for humanity, which views nature as "dirty" and roads and buildings as "clean". The character was also designed to be easy for children to draw.

, a red flight suit with a yellow collar, a bushy mustache, and black pants with two white buttons. This rotund design was influenced by Ohshima's hope that he would be easy for children to draw. Eggman was also based on people Ohshima considered "nerdy, socially awkward, a tinker-type with glasses, a mustache, and a fat belly." Until 1994, Sega of America depicted Eggman in promotional material and game artwork as gloveless and with black, iris-less eyes; whether or not this was a misinterpretation of the game's sprite-work or an intentional design choice to make him more menacing is unknown. Sonic Team's Yuji Uekawa redesigned Eggman and other series characters for ''Sonic Adventure'' in 1998. Eggman's updated design added goggles to his head and gave him a more detailed red

In most of the 2D ''Sonic'' games, the player has to hit Robotnik eight times in order to defeat him. In most 3D ''Sonic'' games since 1998's ''Sonic Adventure'', Eggman may serve as a boss at one or more points in the game, although he usually does not serve as the final boss. Many of the final bosses in these more recent games are former allies of Eggman who then betrayed him, while others are a third party with no connection to Eggman whatsoever.

Eggman tasks Sage with finding a way out of the digital realm while he explores. However, while doing so, Sage also takes it upon herself to dissuade Sonic from freeing his friends, whom she imprisoned after they all arrived on the Starfall Islands, as she is aware of unknown but devastating consequences that would result from his mission. Throughout the journey, Sage slowly becomes influenced by Sonic's compassion and loyalty to his friends and the world as a whole. As such, Sage develops an affectionate regard for Eggman, coming to address him as "father", and he in turn begins to regard her as his "daughter". Despite her efforts to galvanize the Titans, the Ancients' guardian robots who protect the Chaos Emeralds, against the heroic hedgehog, Super Sonic is able to destroy all three and free Tails, Amy, and Knuckles, but in doing so, releases a malevolent cosmic entity known only as the End. The End had destroyed the Ancients' homeworld centuries ago and was imprisoned in Cyber Space by the four leaders of the beings, but had managed to manipulate Sonic into freeing it. Sonic becomes corrupted by the cyber energy running through him as Amy, Tails, Knuckles, and Eggman are released from Cyber Space, with Eggman gloating at his nemesis' apparent demise. However, unwilling to leave him to his fate, Tails, Amy, and Knuckles sacrifice their freedom to restore Sonic to normal, and with Sage's help, battle and eventually destroy the End at its full power, but at the apparent cost of Sage's life. However, after integrating the Ancients' technology with his own, Eggman is able to reawaken Sage's consciousness in his own neural network, to his relief.

In this new backstory, set on the planet Mobius, Dr. Ivo Robotnik was originally a benevolent scientist named Dr. Ovi Kintobor ("Ivo" and "Robotnik" backwards; " ovi-" is also a prefix meaning "egg"), a friend to Sonic who helped to develop the hedgehog's super-speed.

. Eventually, he receives the moniker "Eggman" from Sonic after the egg-shaped designs of his robots. He works alongside his loyal assistant, Agent Stone. Robotnik uses one of Sonic's quills to power up his machines to match Sonic's speed, but is eventually defeated by Sonic. He is transported to a planet filled with mushrooms, where he shaves his head and grows out his moustache over the course of 87 days, making him further resemble his in-game appearances, as he plots his revenge against Sonic. By the second film, Robotnik had spent 243 days (about eight months) on the mushroom planet. In the events of the film, he teams up with Knuckles to defeat Sonic and locate the Master Emerald. Upon locating the Emerald, Robotnik betrays Knuckles and absorbs it, intending to use its power to conquer the universe. In Green Hills, he uses his new powers to create a giant robotic replica of himself (which resembles the Death Egg robot from the games), but is defeated after Knuckles knocks the Master Emerald out of him and Sonic uses the Chaos Emeralds to transform into Super Sonic and destroy the robot. Robotnik's whereabouts and living status are unknown by the end of the film.

In an effort to stop Shadow the Hedgehog, he forms an alliance with Sonic, but betrays him upon learning his grandfather Gerald Robotnik is working with Shadow to activate the Eclipse Cannon, an advanced space weapon. Much to the dismay of Agent Stone, Robotnik develops a close connection with Gerald. Robotnik turns on Gerald upon learning he intends on using the Eclipse Cannon to completely annihilate the Earth as revenge for his late granddaughter Maria's death. In an ensuing battle between the two men, Gerald nearly kills Robotnik, but is saved by Tails and Knuckles who help him kill Gerald. Realizing that he only has the option to save the Earth rather than conquer it, Robotnik helps Tails and Knuckles steer the Eclipse Cannon away from the Earth during its firing sequence, accidentally slicing off part of the Moon. When the Eclipse Cannon’s reactor core begins to melt down and is set to explode, Shadow proceeds to push it away from Earth while Robotnik attempts to stabilize the reactor. In his final moments, Robotnik broadcasts a message to Stone, proclaiming his friendship and appreciation for him, before the Eclipse Cannon explodes with him still inside.
