At the start of the "[[Death Egg saga]]", Eggman invaded [[South Island]], kidnapping its [[Animals]] to use as fuel sources for his new robot army, the [[Badnik]]s. His goal was to find the six [[Chaos Emerald]]s said to rest there to build weapons of mass destruction. However, Sonic secured the Emeralds first and expelled the doctor from the island.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = June 23, 1991 |game = Sonic the Hedgehog (1991){{!}}Sonic the Hedgehog |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref name="Sonic1JPManual" /> Eggman later chained [[Little Planet]] during its annual appearance over [[Never Lake]], coveting its [[Time Stone]]s to control time. He was also served by [[Metal Sonic]], a robotic doppelgänger of Sonic. Despite his efforts, his plans were foiled by Sonic once again.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = June 23, 1991 |game = Sonic the Hedgehog (1991){{!}}Sonic the Hedgehog |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref name="CDJPManual">''[[Sonic the Hedgehog CD]]'' ([[Sega CD]]) Japanese instruction booklet, pgs. 4-5.</ref><ref name="CD2011Instructions" /> He eventually travelled to [[West Side Island]] to find the seven Chaos Emeralds, this time to power his space station, the [[Death Egg]]. Although Sonic and his new friend, [[Miles "Tails" Prower|Tails]], got the gems first, Eggman launched the Death Egg anyway.<ref name="Sonic2">{{Cite game |dev1 = [[Sega Technical Institute]] |date = November 24, 1992 |game = Sonic the Hedgehog 2 |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref name="Sonic2JPManual">''[[Sonic the Hedgehog 2]]'' ([[Sega Mega Drive]]) Japanese instruction booklet, pgs. 4-5.</ref> His success was short-lived however, as Sonic boarded it and damaged it,<ref name="Sonic2" /> causing it to plummet to [[Angel Island]], kept in the sky by the [[Master Emerald]]. He falsely told its guardian, [[Knuckles the Echidna]], that Sonic and Tails were hunting for the Chaos Emeralds, buying him time to repair the Death Egg.<ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = February 2, 1994 |game = Sonic the Hedgehog 3 |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref name="S3JPManual">''[[Sonic the Hedgehog 3]]'' ([[Sega Mega Drive]]) Japanese instruction manual, pgs. 4-6.</ref> Once the spaceship was complete, Eggman betrayed Knuckles and stole the Master Emerald to fuel it.

Eggman would go on to hatch more schemes to take over the world, like building a [[Death Egg mk.II]] around Little Planet<ref>{{Cite game |dev1 = [[Sonic Team]] |dev2 = [[Dimps]] |date = May 15, 2012 |game = Sonic the Hedgehog 4: Episode II |system = PC |pub = [[Sega]]}}</ref> and discovering a gem known as the [[Phantom Ruby]].<ref>{{Cite game |dev1 = [[Christian Whitehead]] |dev2 = [[Headcannon]] |dev3 = Pagoda West Games |date = August 15, 2017 |game = Sonic Mania |system = Nintendo Switch |pub = [[Sega]]}}</ref> In one incident, he even met an older version of himself to defeat Sonic.<ref name="Generations">{{Cite game |dev1 = [[Sonic Team]] |date = November 1, 2011 |game = Sonic Generations |system = PC |pub = [[Sega]]}}</ref> Each time, however, Eggman would fail.

Eggman eventually unleashed a deity of destruction known as [[Chaos]]. His plan was to feed him the seven Chaos Emeralds and use him to destroy [[Station Square]] to build [[Eggmanland]] on its ruins. Central to his scheme were also the [[Egg Carrier]] airship and the [[E-100 Series]] Badnik robots.<ref name="AdventureTokyoInternational">{{Cite book |title=Sonic Adventure Tokyo International Forum Unveiling Booklet |date=August 22, 1998 |chapter=All Star Cast |page=9}}</ref> Although he came close to achieving his goal, giving Chaos six of the Emeralds, Sonic and his friends ultimately destroyed the Egg Carrier and seemingly killed Chaos. Devastated, Eggman attempted a suicide attack on Station Square that was foiled by Tails. Not long after, he rediscovered Chaos but was knocked out by it as it took the final Emerald, rampaging on Station Square on his own. The doctor tried to stop him with the [[Egg Carrier 2]], but was effortlessly defeated. He survived, only turning up again just in time to witness Sonic's victory against Chaos before withdrawing.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = September 9, 1999 |game = Sonic Adventure |system = Dreamcast |pub = [[Sega]]}}</ref>

Eggman later discovered his grandfather's diary, which detailed a top-secret project called "[[Project Shadow]]". Intrigued by this lost research, he infiltrated the military facility on [[Prison Island]] and released [[Shadow the Hedgehog]], the "Ultimate Life Form" created by Gerald. Together with Shadow and [[Rouge the Bat]], Eggman sought to gather the Chaos Emeralds to power the [[Eclipse Cannon]], a weapon aboard the [[Space Colony ARK]] capable of destroying planets. His ultimate goal was to use the ARK to blackmail the world into submission. Despite initial successes, including activating the Eclipse Cannon, Sonic and his friends thwarted Eggman's plans. He was forced to team up with his adversaries after activating a doomsday program that would cause the ARK to crash-land into Earth, culminating in Shadow's apparent sacrifice.<ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = June 23, 2001 |game = Sonic Adventure 2 |system = Dreamcast |pub = [[Sega]]}}</ref>

Following this incident, Eggman discovered that Shadow was still alive and placed him in stasis, mass-producing [[Shadow Android]]s with his data;<ref>{{Cite game |dev=[[Sega Studio USA]] |date=November 18, 2005 |fullgame=[[Shadow the Hedgehog (game)|Shadow the Hedgehog]] |system=PlayStation 2 |pub=[[Sega]] |area=[[Devil Doom]] |quote='''Doctor Eggman''': Everyone thought you'd [Shadow] died during that horrible incident [''Sonic Adventure 2'']... but I rescued you with one of my robots... You lost your memories, that's all.}}</ref> Shadow would eventually be freed by Rouge. At the same time, Metal Sonic, as [[Neo Metal Sonic]], went rogue and took over the Eggman Empire. Trapped in the [[Egg Fleet]], the doctor contacted [[Team Chaotix]], who eventually rescued him. He then joined Sonic and his friends in defeating Neo Metal Sonic.<ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = January 6, 2004 |game = Sonic Heroes |system = Nintendo GameCube |pub = [[Sega]]}}</ref> Soon after, Eggman attempted to control [[Emerl]], an ancient weapon, but Sonic destroyed the robot after it ran amok.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = January 5, 2004 |game = Sonic Battle |system = Game Boy Advance |pub = [[Sega]]}}</ref> Eggman then engaged with the alien [[Black Arms]],<ref>{{Cite game |dev=[[Sega Studio USA]] |date=November 18, 2005 |fullgame=[[Shadow the Hedgehog (game)|Shadow the Hedgehog]] |system=PlayStation 2 |pub=[[Sega]]}}</ref> and later tried to exploit the power of the sun god [[Solaris]], an event undone after Sonic time traveled to erase Solaris from existence.<ref>{{Cite game |dev1 = [[Sega Studio USA]] |date = November 14, 2006 |game = Sonic the Hedgehog (2006){{!}}Sonic the Hedgehog |system = Xbox 360 |pub = [[Sega]]}}</ref> In another incident, Eggman shattered Earth with the [[Chaos Energy Cannon]], unleashing [[Chip|Light]] and [[Dark Gaia]]. His plan was to harness Dark Gaia's power to build Eggmanland, but Sonic thwarted his plans and restored the planet.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 18, 2008 |game = Sonic Unleashed |system = Xbox 360 |pub = [[Sega]]}}</ref>

Later, Eggman learned of the [[Wisp]]s, aliens containing [[Hyper-go-on]] energy, which he planned to use for a mind control cannon to conquer the universe. He chained the Wisps' home planets to an interstellar amusement park, [[Egg Planet Park]], which he falsely claimed in public was built to redeem himself. However, Sonic and Tails uncovered his plan, freed the Wisps, and destroyed the park.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 16, 2010 |game = Sonic Colors |system = Wii |pub = [[Sega]]}}</ref> Stranded in space, the doctor discovered the [[Time Eater]], a deity that could control spacetime, and used the creature to kidnap many locations from Sonic's past, teaming up with his past self, Classic Eggman.

Eggman later re-discovered the [[Phantom Ruby]] and used it to empower [[Infinite]], his new right-hand man. With this power, Eggman defeated Sonic and imprisoned him on a rebuilt Death Egg, allowing him to conquer the world. However, he was opposed by Sonic's friends, who formed the [[Resistance]], triggering the [[War to Take Back the Planet]]. Six months later, the Resistance freed Sonic and was joined by Classic Sonic. Despite Eggman's efforts to foil them, the heroes liberated most of the planet and defeated Infinite. Eggman then used the Phantom Ruby and the [[Death Egg Robot (Sonic Forces)|Death Egg Robot]] in a final effort to win the war, but was ultimately defeated by Sonic and his friends.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 7, 2017 |game = Sonic Forces |system = Nintendo Switch |pub = [[Sega]]}}</ref>

Most recently, Eggman sought to exploit the advanced technology created by the alien [[Ancients]] on the [[Starfall Islands]]. He created an AI named [[Sage]] for protection but became trapped in [[Cyber Space]]. Over time, he inadvertently bonded with Sage, whose abilities far exceeded his expectations. Sonic eventually destroyed the islands' [[Titan (Sonic Frontiers)|Titans]], freeing his friends and Eggman, but also releasing [[The End]], a world-threatening entity. Sonic defeated The End with Sage's help, culminating in Sage's sacrifice. Devastated, Eggman later recovered Sage's data and partially restored her much to her joy.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 8, 2022 |game = Sonic Frontiers |system = PlayStation 4 |pub = [[Sega]]}}</ref>
