Dr. Eggman

Dr. Ivo Robotnik, better known as Dr. Eggman, is the primary antagonist in the Sonic the Hedgehog franchise and the arch nemesis of Sonic the Hedgehog, much in the same manner as Bowser's conflict with Mario. In a similar vein to Mario and Bowser, he has occasionally teamed up with Sonic to face greater threats in their homeworld. Dr. Eggman is a mad scientist with a very high IQ of 300, and his goal is to dominate the world and build the Eggman Empire.

Dr. Eggman, like Wario, is a playable character in every Mario & Sonic series installment. Throughout the series, Dr. Eggman has been voiced by Mike Pollock, who has voiced Dr. Eggman in general since Shadow the Hedgehog. The series' story modes often feature Dr. Eggman and Bowser scheming together.

Mario & Sonic at the Olympic Games
Dr. Eggman, as well as several other Sonic the Hedgehog series characters, appear in Mario & Sonic at the Olympic Games. He is a Skill player who, despite his large size, is unusually fast. To compensate, Dr. Eggman is lacking in power and has low stamina.

Mario & Sonic at the Olympic Winter Games
Eggman appears as a playable character in the sequel Mario & Sonic at the Olympic Winter Games. He appeared in the first trailer for the game along with Sonic the Hedgehog, Mario, and Wario. He is again a skill type character.

In the Nintendo DS version, Dr. Eggman is one of the two main antagonists of Adventure Tours, the other one being Bowser. Both of them try to stop the 2010 Olympic Winter Games from occurring by capturing all the snow spirits in favor of hosting their own Olympic Games. However, the two were thwarted by Mario, Sonic, and their friends.

Mario & Sonic at the London 2012 Olympic Games (Wii)
Dr. Eggman appears once again as a Skill type playable character in the Wii version of Mario & Sonic at the London 2012 Olympic Games. He has a very high Technique level and performs well at events such as Gymnastics. He appears alongside all of the other athletes at the start of the game's opening, as well as later appearing competing in Badminton - Doubles and Track Cycling - Team Pursuit. An outfit based on Dr. Eggman can be unlocked for Miis to wear.

Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)
In the Nintendo 3DS version, Dr. Eggman is included in the Tricksters class and is hence only playable in certain Events.

In the Story Mode, Dr. Eggman first appears in the opening, in which he and Bowser reveal and begin their plan to cover London with Phantasmal Fog to prevent the Olympic Games from happening as they had not been invited. Dr. Eggman is then discovered to be partially behind the appearance of the fog in The Mysterious Thief when Rouge remembers that he brainwashed her, and also in Enter Bowser?! when Bowser Jr. accidentally mentions him having discussions with Bowser. Toad reveals that he heard Dr. Eggman was at the British Museum in Mario and Sonic, and he and the Heroes group later find Eggman Nega there filling in as a favor. They later find out that Dr. Eggman had visited the museum to gather information about the Phantasmal Fog. Wario later encounters Dr. Eggman and defeats him in an Event in an attempt to destroy a Fog machine and get some money, but the machine is revealed to be a hologram and Dr. Eggman escapes. Wario and Waluigi later find him with Metal Sonic, and defeat them in an Event to destroy the real fog machine and try to get some compensation. In The Banana Incident, it is also revealed that Dr. Eggman had installed a chip in Omega to have him perform task for him. In Clear Skies Again, it is revealed that the Dr. Eggman Wario and Waluigi cornered was a hologram, and Dr. Eggman releases the fog over London once again. In To the Ruins!, Omega recovers enough of his memory to establish more of the details of Dr. Eggman's plan, as well as revealing his lab to be within Big Ben. In The Grand Showdown, Mario, Luigi, Sonic and Tails arrive to confront Dr. Eggman and Bowser, who have been powered up by the Phantasmal Fog, and Mario and Sonic defeat them both in an Olympic Event. After the fog is sealed away, Dr. Eggman and Bowser reveal their motives for their plan, and Toad calls them over the walkie-talkie to inform them that they can still compete if they go to the Main Stadium, and the pair accept the offer, later appearing at the opening ceremony. Dr. Eggman is mentioned to be causing trouble with his robots in the first two Challengers bonus episodes, and appears in Junior Triumphant, in which he agrees to let Bowser Jr. challenge Metal Sonic, aiming to help refine the robot. Dr. Eggman also appears in the Tricksters Bonus episodes, in which he trains Metal Sonic to improve him for the Olympic Games, first against Waluigi, and later against Wario, from whom he obtains the Fog urn. In The Fog Returns, he uses the Phantasmal Fog from the urn to create an imposter of Sonic, and later explains the history of the fog to Orbot, Cubot and Metal Sonic. Dr. Eggman's invitation is frequently referred to in the Girls Bonus episodes, as it is accidentally ruined twice, delaying the invitations being sent out, causing him and Bowser to investigate the delay in The Real Beginning. After losing to Peach and Amy in an event, the pair wait for their invitations, but find them dropped by some Toads and mistake them for love letters, causing them to leave and head off sightseeing. A badge of Dr. Eggman can also be obtained from the badge machine.

Dr. Eggman's bio from the defunct website erroneously suggests that he is a good character to use in the Rings event despite being unplayable in said event.

Mario & Sonic at the Olympic Games

 * Profile: Although the devious Dr. Eggman has great Skill-based abilities, he also is quite powerful. His huge, lumbering frame doesn't give the impression that he would be good at gymnastics, but believe it or not, he can handle the trampoline and vault quite well.
