Owing to his delusions of grandiosity, Eggman refuses to let others cause destruction outside ''his'' direction. This was shown when [[Chaos]] betrayed him and flooded Station Square; Eggman had planned this but refused to let Chaos continue aimlessly. He is intolerant of senseless destruction by third parties, especially if it interferes with his plans, as seen when the [[Black Arms]] invaded the world.<ref name="ShadowUSManual">''[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]'' ([[Nintendo GameCube]]) United States instruction booklet, pg. 8.</ref> His goal is to rule the world, not destroy it, as world conquest would be rendered impossible with no world to conquer.<ref name="DestroyWorld">[[Sonic Team]] (February 27, 2004).

In the IDW Comics, Dr. Eggman is an evil and megalomaniacal genius who is constantly planning to take over [[Earth]] and those beyond his. Showing contempt for how "filthy" and "irregular" the world is, he views himself as obligated to perfect it by ridding it of what he deems as imperfections, including hunger, disease and, above all, free will.<ref name="StH16">[[IDW Sonic the Hedgehog Issue 16|''Sonic the Hedgehog'' #16]], "Infection"</ref> Arrogant, raucous and explosive, he believes that he is bringing peace and unity to Earth under his brilliant leadership, but has no qualms about destroying the Earth and all life on it before moving on to another world if needed.<ref name="StH12">[[IDW Sonic the Hedgehog Issue 12|''Sonic the Hedgehog'' #12]], "The Cost of the Battle for Angel Island"</ref><ref name="StH23">[[IDW Sonic the Hedgehog Issue 23|''Sonic the Hedgehog'' #23]], "The Last Minute, Part 3"</ref> He also does not accept the world as it is as a whole. Instead, he wants to transform it to his liking and set up terrifying amusement parks like [[Eggman Land (IDW)|Eggman Land]]. His reason for doing so is that he simply likes amusement parks and does not care about their effectiveness; all he wants is to control precisely what his enemies experience in their last moments. Eggman likewise prefers to show up and claim responsibility whenever he is carrying out his villainous deeds and make himself known to his enemies after he comes back from a defeat;<ref name="StH1">[[IDW Sonic the Hedgehog Issue 1|''Sonic the Hedgehog'' #1]], "Fallout, Part 1"</ref><ref name="StH13">[[IDW Sonic the Hedgehog Issue 13|''Sonic the Hedgehog'' #13]], "Calling Card"</ref> as put by [[Sonic the Hedgehog/IDW Publishing|Sonic]], subtlety is not Eggman's forte.<ref name="StH2">[[IDW Sonic the Hedgehog Issue 2|''Sonic the Hedgehog'' #2]], "Fallout, Part 2"</ref>

Eggman has a tendency to often personalize his works by plastering his face or overall image all over his creations, like the [[Faceship]].<ref name="StH16" /> Other times, he focuses his work around a specific theme.<ref name="StH4">[[IDW Sonic the Hedgehog Issue 4|''Sonic the Hedgehog'' #4]], "Fallout, Part 4"</ref> He also uses every situation he can get to personally destroy his enemies and move closer to the realization of his ambitions, as well as evade every instance where he is supposed to take responsibility for his actions and the consequences that follows as a result of his half-baked schemes.<ref name="StH23" /> Having little to no honor either, Eggman is likewise depicted as having almost zero compassion and regard for others than himself. Cunning and deceitful, he will use and manipulate his minions and subordinates however he sees fit without a pang of remorse, not caring about ideals such as loyalty. He similarly uses them as tools that he can get rid of at any time after they either fail him or have served their purpose. Noticeably, he tricked [[Rough the Skunk|Rough]] and [[Tumble the Skunk|Tumble]] into turning themselves into [[Zombot]]s despite the skunk brothers being "perfect minion fodder" for him and that he owed them a deal for helping him back to his senses while he was an amnesiac.<ref name="StH15">[[IDW Sonic the Hedgehog Issue 15|''Sonic the Hedgehog'' #15]], "Patient Zero"</ref> He similarly seeks to enslave the whole world with fear. He is also shown to be extremely ungrateful and sadistic, as some of his first victims during the [[Metal Virus]] plague were the people of [[Windmill Village]] who took care of him while he was suffering from amnesia simply to test his virus and demonstrate "no good deed goes unpunished".<ref name="StH16" />
