At the start of the [[Death Egg saga]], Sonic learned that Eggman had invaded [[South Island]] to seek out the [[Chaos Emerald]]s resting there, kidnapping the local [[Animals]] and turning them into robots called "[[Badnik]]s".<ref name="Sonic1JPManual" /> After expelling 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> he thwarted his plan to capture [[Little Planet]] and adquire its [[Time Stone]]s to conquer spacetime, meeting [[Amy Rose]] along the way.<ref>{{Cite game |dev1 = [[Sega]] |date = November 23, 1993 |game = Sonic the Hedgehog CD |system = Sega CD |pub = Sega}}</ref> Soon after, Sonic travelled to [[West Side Island]] and met [[Miles "Tails" Prower]], who joined him in stopping Eggman from launching his [[Death Egg]] space station.<ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = November 24, 1992 |game = Sonic the Hedgehog 2 |system = Sega Mega Drive |pub = [[Sega]]}}</ref> However, the Death Egg crash-landed on [[Angel Island]], whose guardian, [[Knuckles the Echidna]], was fooled into thinking Sonic and Tails had evil intentions. The duo traveled through Angel Island, sabotaging the Death Egg's relaunching and causing it to crash into [[Lava Reef]]. They eventually befriended Knuckles and destroyed the space station for good, with Sonic transforming into [[Super Sonic]] with the seven Chaos Emeralds to chase Eggman into space.<ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = February 2, 1994 |game = Sonic the Hedgehog 3 |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = October 18, 1994 |game = Sonic & Knuckles |system = Sega Mega Drive |pub = [[Sega]]}}</ref>

In the aftermath, Sonic would find himself facing more schemes from Eggman. Amongst other adventures, he would destroy the [[Death Egg mk.II]],<ref>{{Cite game |dev1 = [[Sonic Team]] |dev2 = [[Dimps]] |date = May 15, 2012 |game = Sonic the Hedgehog 4: Episode II |system = PC |pub = [[Sega]]}}</ref> face a bounty hunter known as [[Fang the Hunter]],<ref>{{Cite game |dev1 = [[Aspect]] |date = November 1994 |game = Sonic the Hedgehog Triple Trouble |system = Sega Game Gear |pub = [[Sega]]}}</ref> and meet an older version of himself.<ref name="Generations">{{Cite game |dev1 = [[Sonic Team]] |date = November 1, 2011 |game = Sonic Generations |system = PC |pub = [[Sega]]}}</ref> Despite Eggman's persistence, Sonic emerged victorious in every situation.

Sonic eventually found out that Eggman was seeking to tame [[Chaos]], an ancient god of destruction, to annihilate [[Station Square]]. He teamed up with Tails to acquire the Chaos Emeralds before Eggman did to power up the beast. Along the way, he met the ancient echidna spirit [[Tikal]], and from her learned much of the Chaos's violent history. Ultimately, despite Sonic's efforts, Chaos harnessed the seven Emeralds and transformed into [[Perfect Chaos]]. Sonic transformed into Super Sonic and defeated Perfect Chaos, reverting the creature to his original peaceful form.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = September 9, 1999 |game = Sonic Adventure |system = Dreamcast |pub = [[Sega]]}}</ref>

Sonic was later falsely framed as an escapee by the [[Guardian Units of Nations]] (G.U.N.) military. While fleeing persecution, he discovered that he had been mistaken with [[Shadow the Hedgehog]], who had teamed up with Eggman to adquire the seven Chaos Emeralds. Sonic partnered with his friends to uncover Eggman's plan, which was to hold the world hostage with the [[Eclipse Cannon]], a superweapon held onboard the [[Space Colony ARK]]. The heroes infiltrated the colony to sabotage the doctor's scheme. Although they ultimately failed, both parties learned that they had been fooled by an elaborate revenge plan posthumously initiated by Eggman's late grandfather, [[Gerald Robotnik]]. With the colony on a rapid collision course with Earth, Sonic teamed up with his friends and foes and saved the world.<ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = June 23, 2001 |game = Sonic Adventure 2 |system = Dreamcast |pub = [[Sega]]}}</ref>

Sonic would later form "[[Team Sonic]]" alongside Tails and Knuckles to foil [[Neo Metal Sonic]], a transformed version of Metal Sonic that was masquareding as Eggman. After a series of battles against rival teams, the group defeated the robot.<ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = January 6, 2004 |game = Sonic Heroes |system = Nintendo GameCube |pub = [[Sega]]}}</ref> Afterwards, Sonic discovered and befriended [[Emerl]], who was later discovered to be an ancient weapon of mass destruction. He was forced to destroy the robot to save the world after Eggman attempted to control Emerl.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = January 5, 2004 |game = Sonic Battle |system = Game Boy Advance |pub = [[Sega]]}}</ref> In another adventure, Sonic met a time traveller known as [[Silver the Hedgehog]] and found himself embroiled in a conflict revolving around a sun deity called [[Solaris]] that was split into two, leading to him protecting [[Princess Elise the Third]] from Eggman and ultimately going to the past 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> Later, when Eggman shattered [[Earth]] and unleashed an entity called [[Dark Gaia]], Sonic was infused with a [[Werehog]] transformation and embarked on a journey around the planet to restore it.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 18, 2008 |game = Sonic Unleashed |system = Xbox 360 |pub = [[Sega]]}}</ref>

In a subsequent adventure, Sonic befriended aliens called [[Wisp]]s and destroyed Eggman's [[Egg Planet Park]], which he was using as a cover-up for world conquest.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 16, 2010 |game = Sonic Colors |system = Wii |pub = [[Sega]]}}</ref> Sonic would later celebrate [[Sonic's birthday|his birthday party]] when he and his friends were kidnapped by the [[Time Eater]], a deity of time later revealed to be controlled by Eggman. Trapped in a void known as [[White Space]], Sonic met a younger version of himself known as Classic Sonic and traveled through various points of his earlier life. The Sonics eventually gathered the seven Chaos Emeralds and destroyed the Time Eater before parting ways.<ref name="Generations" /> Afterwards, Sonic and Tails pursued Eggman to the [[Lost Hex]], where they were forced to team up with the doctor after the locals, the [[Deadly Six]], took over Eggman's inventions to destroy the world.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = October 29, 2013 |game = Sonic Lost World |system = Wii U |pub = [[Sega]]}}</ref>

Sonic was later defeated by [[Infinite]], Eggman's new right-hand man who was using a mysterious gem known as the [[Phantom Ruby]] to empower himself. He was then held captive onboard the rebuilt Death Egg. Without his nemesis to foil him, Eggman conquered the world but was opposed by Sonic's friends, who formed a guerrilla group known as the [[Resistance]], triggering the [[War to Take Back the Planet]]. After six months of captivity, Sonic was freed by a Resistance recruit known as the "[[Avatar]]" and reunited with Classic Sonic. The trio, alongside the rest of the Resistance, faced off against Eggman's army and Infinite, ultimately overthrowing the doctor's regime.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 7, 2017 |game = Sonic Forces |system = Nintendo Switch |pub = [[Sega]]}}</ref>

Guided by a mysterious voice, Sonic was tasked with destroying the islands' [[Titan (Sonic Frontiers)|Titans]] to rescue his friends. He also met [[Sage]], an AI created by Eggman, who was trapped in Cyber Space. After destroying the Titans and freeing his friends and Eggman, Sonic inadvertently released a malevolent entity called [[The End]].
