Pre-history[]
Battle for the Master Emerald[]

The Owl Warriors take the Master Emerald to Earth
- "This world has been chosen for a very important reason. It's the secret location of the Master Emerald."
- ―Longclaw to Sonic the Hedgehog[src]
Ages ago, the Echidna tribe's misuse of the mystical Master Emerald for chaotic purposes prompted the Owls to take a vow to protect it. To safeguard the powerful artifact, they hid it on Earth, constructing a labyrinth near present-day Hawaii and hiding a compass to its location in modern day Siberia.[1]
20th Century[]
Project Shadow[]

- "Wow. Look at all those stars. They're like diamonds. My grandfather says it can take hundreds of years for the light of a star to reach Earth, and by the time you see it, the star might not even exist anymore. Isn't that crazy?"
"The light shines... even though the star's gone..."
"Yeah. It does. I wonder which one you came from, Shadow."
"I don't know. I don't know anything about my home."
"This is your home, Shadow. Earth." - ―Maria Robotnik and Shadow the Hedgehog[src]
In the 1970s, a large meteor crashed in Oklahoma, United States of America containing Shadow the Hedgehog. Recognizing the immense power of his Chaos Energy, G.U.N. initiated Project Shadow, a secret program aimed at utilizing Shadow's potential to revolutionize humanity's future.
Besides being tested and experimented on, Shadow would oftentimes play with Maria Robotnik, the granddaughter of project leader Gerald Robotnik who moved into G.U.N.'s secluded laboratory. One time, when watching a movie that portrayed aliens as "freaks," Maria noticed the disheartened look on Shadow's face, bringing him above the laboratory to stargaze. Maria told Shadow that a star's light takes years to reach Earth, though the star might be gone by the time it's visible, much to Shadow's fascination. Once asked what star he hailed from, to which Shadow responded unsurely. Maria apprised him that Earth was his home.

Gerald Robotnik is arrested by G.U.N.
By 1974, G.U.N. realized the potential danger Shadow posed and ordered a raid to secure him. The raid resulted in the accidental death of Maria Robotnik. Both Shadow and Gerald were taken by G.U.N. with Shadow placed in stasis on Prison Island, while Gerald secretly began plotting his revenge against humanity.[2]
21st Century[]
Sonic's New Life[]

Young Sonic alone on Earth
- "So what did you expect? A dirty little Hedgehog eating berries and struggling to survive? Think again. Because I am living my best life on Earth!"
- ―Sonic the Hedgehog[src]
Forced to flee his home planet after an Echidna attack in 2013, Sonic was sent to Earth, a planet far removed from Mobius, by his caretaker, Longclaw, who stayed behind to fend off their attackers, sharing a heartfelt goodbye with him before her sacrifice. For the next ten years, Sonic lived in secrecy on Earth.[3] As to remember his origins, Sonic drew a drawing of him and Longclaw on Mobius in what would later become his hideout.[2] He eventually moved near the town of Green Hills and grew emotionally attached to its people, living in his hideout[3] for seven years.[4] While he often observed their daily lives from afar, sometimes subtly interacting with them, the townsfolk remained unaware of his existence.[3]

Sonic snaps a selfie in New York City, New York
By 2019, Sonic traveled around the world, visiting various tourist attractions in a span of eighty seconds. He first explored North America, noting the palm trees and movie stars seen in Los Angeles, California and praising the sweeping arches in Arches National Park, Utah. After remarking the Mayans' taste in architecture when arriving in Chichen Itza, Mexico and all the landmarks and available snacks in New York City, New York, Sonic moved onto Europe. Speeding through the various landmarks in London, England, Sonic wondered if he could acquire the hats worn by the Queen's Royal Guard. Running out of time when visiting the "City of Love" Paris, France, Sonic rolled through Africa, reminded of the song "Walk Like an Egyptian" when passing through Giza, Egypt. In Asia, Sonic apprised India's culture when finding himself in the city of Agra and afterward admired Japan's scenery. He eventually returned in Green Hills, Montana after passing Sydney, Australia and the Outback, listing various other locations he'd like to visit a next time, including Yosemite National Park, the Sahara and Madrid, Spain.[5]
Hunt for Sonic the Hedgehog[]
The energy surge as seen from Earth
- "Twenty minutes ago, an energy surge knocked out power across the entire Pacific Northwest. What do we know?"
- ―Walters to the United States Army[src]
In 2023, after viewing the playoffs, Sonic decided to play a baseball match of his own. Winning at his own game, Sonic held his hand up, expecting a high five, but then he remembered that he was unknown to everyone. He ran around the baseball field at high speeds to vent off his frustration, inadvertently triggering a massive electromagnetic eruption in Green Hills, causing a total blackout across the Pacific Northwest and even disabling a satellite.[3] The signal of the energy surge was picked up by Miles "Tails" Prower's laptop, who subsequently began searching for Sonic.[1]
The blackout prompted the United States Armed Forces to come to the conclusion of contracting Ivo Robotnik to investigate the anomaly in Green Hills. Said doctor found out that the cause was a creature unlisted in Earth's animal kingdom.

Sonic runs on the Great Wall of China
With aid from Tom and Maddie Wachowski, Sonic retrieved his bag of rings atop the Transamerica Pyramid in San Francisco. However, at that moment, Robotnik confronted the three. Robotnik pursued Sonic as he deployed rings leading to various tourist locations, almost injuring a mime and a family in Paris, racing across the Great Wall of China, and damaging the Great Pyramid of Giza in Egypt.

Robotnik is sent to the Mushroom Planet
After racing around the world, Sonic returned to Green Hills and battled Robotnik, eventually gaining a power boost and sending Robtonik to another planet with a ring. Sonic, as a reward, remained on Earth to enjoy a newfound life with the Wachowski family. Robotnik however vowed to make it back to Earth by Christmas.[3]
Re-establishment of G.U.N.[]
- "After the events in San Francisco, a global task force was created, devoted to protecting our planet from alien threats. That day, Guardian Units of Nations was born."
- ―Walters to Maddie and Rachel[src]
After the events of San Francisco, the U.S. government erased all records of Robotnik's existence and seized all of his assets,[3][6] including one agent who would eventually become "The Buyer".[7] With the United States government now knowing about Sonic's existence and the events that followed, Walters reestablished G.U.N. as an international military organization to combat potential alien threats,[1] also granting the Wachowskis an Olive Garden gift card as a reward upon his visit to Green Hills.[3]
Blue Justice Heroics[]

Sonic thwarts Lindsey's crew's plans in Walla Walla, Washington
Known by the public, Sonic was ordered to stay put in the Wachowski Residence while Tom and Wade went ice-fishing. Both parties eventually hear of an ongoing bank robbery occurring in Walla Walla, Washington and immediately traveled there. Sonic defeated Lindsey and her crew of criminals, who tried to take the bank's vault by controlling Doctor Eggman's Flying Eggs. One of the Badniks returned to Eggman's agent Stone with a Control Glove, which included a drive to his manifesto. Stone used to manifesto to take over Karen's coffee shop.[8]

Sonic damages the roads of Seattle, Washington
Months later, Sonic snuck out of his room to travel to Seattle, Washington, shoddily stopping a car heist in progress. The damages spread across Seattle were reported in The Daily Observer newspaper, which Tom showed to Sonic in a lecture regarding the use of his powers.[1]
Tails and Knuckles' Arrivals[]

Tails arrives on Earth
- "Where did you get that?"
"From a little blue menace on the planet called Earth. I'd be happy to show you the way." - ―Knuckles the Echidna and Doctor Eggman[src]
Tails and Knuckles the Echidna simultaneously searched for Sonic. Following his defeat of a ferocious beast in Casino Night, Knuckles recruited Scavengers to help him search for Sonic, following Tails' ring portals. Tails briefly stopped in Hill Top, picking up two chaos energy peaks in Mushroom Planet and Earth on his Miles Electric. Tails opened a portal towards Earth.[8]

Doctor Eggman and Knuckles upon their arrival on Earth
The Scavengers were thwarted by Doctor Eggman after they stepped foot on the Mushroom Planet, Eggman being met by Knuckles afterwards. In their mutual quest for payback, the two became partners when Knuckles was promised to be lead to Sonic if he deployed a ring to Earth. Sonic, enjoying a movie night with the Wachowski family dog Ozzie, was ambushed in the Wachowski Residence, blown into its garden. He was rescued by Tails, invited into a police car that the two drove across town with Knuckles on their tail, seeking the location of the Master Emerald. Sonic and Tails eventually managed to escape and shelter in deputy sheriff Wade Whipple's garage.

Eggman's Egg-Capsule arrives on Earth from space
Knuckles was left hanging on a cliff when Sonic and Tails made their escape, meeting Eggman once more after he called his agent Stone to send down a pod containing a new suit and array of Badniks. Reaching an agreement to both seek for the emerald as long as Knuckles destroys Sonic, Knuckles and Eggman regrouped in a coffee shop that Stone took over.[1]
Race to the Master Emerald[]

- "Okay, quick version. Robotnik is back on Earth and he's after a magic emerald. We need to get it back or the world is doomed!"
- ―Sonic the Hedgehog to Tom Wachowski and Maddie Wachowski[src]
Being told to secure the Master Emerald by Longclaw, Sonic and Tails traveled to Siberia when following Sonic's Safe Worlds Map, taking shelter in a bar due to a snow storm. Assuming human clothing, their covers were blown when Tails' Miles Electric's translations malfunctioned. With the map stolen, Sonic and Tails were forced to partake in a dance battle against the Champ, retrieving the map. The two spent the night in the bar and continued the next day, entering a cave where a mural detailing the War for the Master Emerald is depicted. Acquiring a compass for the emerald from a giant Owl statue, Sonic and Tails reencountered Knuckles and Eggman, Eggman destroying the cave upon launching the missiles of his Egg-Mobile. Sonic and Tails raced up the now tilted statue, Sonic snowboarding down a mountain as Tails followed him with his flight, both being chased by Knuckles and Eggman. Upon their eventual halts, Eggman rendered Tails unconscious with a missile's explosion after stealing the compass, teleporting near the Labyrinth afterwards.

Carrying Tails, Sonic skid down the mountain while calling Tom in Oahu, Hawaii, ordering him to throw a ring to said location. When Tom did, snow covered wedding attendees as Sonic and Tails launched through, the two being captured by the Guardian Units of Nations. Maddie used Tails' gadgets to rescue them and an arrested Tom, Sonic later speeding towards the now revealed Labyrinth to stop Eggman and Knuckles. Meanwhile, in Green Hills, Montana, temporary sheriff Wade Whipple interrogated Stone in the Mean Bean Coffee Café.

The two parties passed through a maze filled with many traps, Sonic hindering Eggman and Knuckles' path to the Master Emerald Shrine. Sonic, set on protecting the shrine, fought Knuckles by the shrine while Eggman steals the emerald, destroying the Labyrinth when teleporting to Green Hills. Sonic and Knuckles saved each other from drowning, making amends on a nearby island before being rescued by Tails piloting his Tornado biplane.[1]
Battle Against the Giant Eggman Robot[]

Team Sonic appears in Green Hills
- "I'm going to enslave humanity and force them to service my machines. First Green Hills, then the universe, then the multiverse, then who knows?! Maybe that'll be enough."
- ―Doctor Eggman to Sonic the Hedgehog[src]
Sonic, Tails and Knuckles teleport to Green Hills, Montana, confronted by a giant storm in the midst of the town, unveiling Eggman's Giant Eggman Robot. Individually, the three make their attempts at stopping Eggman while Tom and Maddie, who traveled to Green Hills by helicopter after convincing Walters of Sonic's cause, evacuated civillians. As their attacks were to no avail, They thusly decided to cooperate, Sonic planning to have Eggman follow him across town while the others infiltrate the robot. Disposing Eggman of the Master Emerald's power, Sonic used the broken emeralds' Chaos Emeralds to transform into Super Sonic, taking Eggman down with the robot. Reunited with the Wachowskis, Sonic, Tails and Knuckles formed a team to protect the Master Emerald and celebrating with a baseball match at the Green Hills Baseball Field.

Walters is informed of Project Shadow
Afterwards, the Guardian Units of Nations investigated the area for signs of Eggman, who was now presumed deceased. During their investigation, an agent reports as they were erasing Eggman from their database and that they found a file regarding Project Shadow.[1]
Battle at the Green Hills Junkyard[]

Team Sonic enters the Green Hills Junkyard
Shortly after,[9] "Team Sonic" was requested to investigate the Green Hills Junkyard, from which weird noises were heard as per Wade Whipple. Sonic, Tails and Knuckles battled and befriended a Flying Egg Badnik named Unit, moving on to collect chili dogs.[10]
Quest to Reno[]

- "I can train you in the ways of the Echidna. Teach you every form of lethal combat. Show you the secrets to all my strength."
"Then, I could use that to challenge Susie in a trial by bowling combat and earn my spot back on the team!"
"Yes. If you take me on this quest to Reno, I will make you a true warrior!" - ―Knuckles the Echidna and Wade Whipple[src]
By 2024, it was clear to Knuckles that Earth is longer under threat by forces such as Eggman, Sonic telling him to accept the planet as his home now that he has no quests to go on. Feeling as if he no longer has a purpose, Knuckles called for the help of his tribe's leader's spirit, Pachacamac, whom tasked Knuckles with training a protégé, Wade Whipple, into becoming an Echidna warrior. Knuckles subsequently persuaded Whipple into inviting him to attend the Bowling Tournament of Champions in Reno, Nevada, vowing to educate his tribe's ways to him along the way.
Upon their leave, ex-agents Willoughby and Mason observe Knuckles and Whipple from the Guardian Units of Nations Headquarters in London, England, Willoughby disabling G.U.N.'s satellite surveillance systems as Mason banished a concerned agent Fairley to the Mushroom Planet. After being given weapons to combat Knuckles with by The Buyer, whom they settled to deliver Knuckles to in exchange for money, Knuckles was confronted and captured in the Neon Nightz Lanes bowling alley,[4] driven to the IceCap Ski Resort. Whipple followed with a master plan he came up with, passing by a local store to enact said plan. It however backfired, alerting the agents. After a fight inside the ski resort, Whipple caused an explosion and created a hole through one of the building's walls, through which he and Knuckles escaped.

Knuckles and Wade arrive at the Whipple Residence
While continuing their travels, Whipple came to find out he is wanted with a price on his head, deciding to take refuge in his old childhood home in Boise, Idaho.[11] Spending the night and a Shabbat dinner with his mother Wendy and sister Wanda, the residence was suddenly under attack by a group of bounty hunters, which Knuckles and the Whipples defeated.[12] The next morning, Wade was kidnapped and caged by the bounty hunter Jack Sinclair, the leader of the Renegades from which Wade was kicked out of. Calling Knuckles for help, Wade was instead told to break out of the cage himself by asking for Pachacamac's guidance. Entering the astral plane of the Great Battleground in the Sky, he met Pachacamac, who taught him how to access the power inside his heart, otherwise known as the Flames of Disaster. With this knowledge, Wade promptly broke out, challenging Sinclair to a duel he won. Claiming his motorbike and jacket, he changed the "Renegades" into the Warriors, arriving back home to his family and Knuckles.[13]
Arrival in Reno[]
Knuckles fights for his home
- "You fight to honor your family! You fight to protect your friends! And now, you have something new to fight for. A home!"
- ―Wade Whipple to Knuckles the Echidna[src]
The Whipples moved on to Reno, Nevada,[13] entering the National Bowling Stadium. Wade met his long-lost father Pistol Pete Whipple, an expert bowler whom he will compete against in the tournament, while Willoughby and Mason were brought back to The Buyer in his lair, where he decided to grant the agents another chance, threatening their lives. Entering the finals of the tournament, Pistol Pete invites Wade to his penthouse, where Wade saw his mother and sister being held hostage by the agents. Wade unwillingly lead Knuckles to them,[7] the agents not knowing that Knuckles knew of their attack in advance. Following a battle in the suite, where Willoughby and Mason imploded between two ring portals, Knuckles encouraged Wade to finish his match against Pistol Pete. Wade eventually won, Knuckles crashing through the walls of where the event took place during his battle against The Buyer. A weakened Knuckles, robbed of his chaos energy, was aided by Wade, whom tried to fend off the powered Buyer. Listening to Wade's speech about how Knuckles has to fight for his "home," Earth, Knuckles awoke to defeat The Buyer and defend the planet, using the Flames of Disaster against him. Knuckles and Wade later returned back to Green Hills, Montana with the tournament's trophy in hand.[14]
Sonic's Bearthday[]

Shadow breaks out of Prison Island
- "Today's the anniversary of the day you came to Earth, bud! It's your Earth day birthday."
- ―Tom Wachowski to Sonic the Hedgehog[src]
On Prison Island, G.U.N. security monitor Kyle Lancebottom surveilled Shadow the Hedgehog. With the systems safeguarding Shadow's containment tank breached by Gerald Robotnik, Shadow broke free when reminded of his trauma. Breaking out of the facility after thwarting a troop of soldiers, Shadow skated across the Pacific Ocean[2] towards the Rainbow Bridge, scaling it when surrounded by G.U.N. once more. Shadow refused to surrender and made his way to Shibuya Crossing, Shibuya. Followed by G.U.N. and the Tokyo Metropolitan Police Department, Shadow fought and defeated the authorities.

The anniversary of Sonic's arrival on Earth is celebrated
Meanwhile, in Green Hills, Sonic had his anniversary of when he first came to Earth, named his "Bearthday," celebrated by the Wachowskis and his friends. Sonic thanked Tom for the party the next morning during their walk through the town's forests, Sonic coming across the cave he used to reside in. Tom followed him as Sonic picked up old memories, uncovering the drawing Sonic had made of him and Longclaw together on Mobius years ago. Sonic, questioning if Longclaw would be proud of him, was reassured that she would as he never let pain change him and was further taught that the right choices will come from the heart. A G.U.N. Helicopter later descended near the Wachowskis' camping site, director Rockwell requesting Team Sonic's aid in neutralizing a threat in Tokyo, Japan. The team was reminded to make good choices as they left.[2]
Pursuing Shadow the Hedgehog[]

Exiting a ring portal thrown in Green Hills, Montana, Team Sonic arrived in Tokyo, Japan. The team later jumpede out of the helicopter when hovering above Shibuya Crossing, skydiving down to said pedestrian scramble. Upon safely landing, the team was confronted by Shadow, who scaled a pile of wrecked G.U.N. and police vehicles. Despite Shadow's warning not to engage in battle, he thwarted Knuckles' impending attack, throwing him into a cart after kicking him into the air. Shadow further pummeled the rest after the team regrouped, launching Sonic into the air and slamming him back into the street. Shadow equipped a G.U.N. motorcycle and laser gun, urging Sonic not to follow him as he made his escape. Sonic ignored Shadow's caution and chased him through the busy streets of Tokyo, Sonic hanging onto Shadow's motorbike when Shadow teleported to the Tokyo Skytree. Shadow revved his bike up with chaos energy, allowing for him to drive up the building with Sonic still on his tail. Shadow drove past the Skytree's top as Sonic stood atop the building, both Hedgehogs jumping towards each other imbued with chaos energy. When their fists met, the blast caused a brief citywide blackout.

The Mecha Crab is revealed to Team Sonic
Met by Tails and Knuckles on the Skytree, Sonic suggested somewhere to regroup, Tails bringing the team to the Chao Garden, a Japanese restaurant, to speak with Walters. Walters told them of Project Shadow, succumbing to the injuries he received from an attack by Doctor Eggman's Flying Eggs. The robots disabled by Stone, who crashed the establishment with a motorcycle, Team Sonic left to chase Stone after being given a keycard built for G.U.N.'s Eclipse Cannon. Apprehending Stone by a dock, Stone invited Team Sonic into the Mecha Crab, in which Eggman had been hiding since his defeat in 2023. Eggman and Stone denied any involvement in the attack on Walters, Eggman proving this by tracking down the true culprit's base of operations. Reluctantly, Team Sonic partnered with Eggman and Stone to stop Shadow and Gerald.

Sonic and Eggman arrive at Gerald Robotnik's Laboratory
After Shadow made it to the abandoned G.U.N. facility he was raised in, picking up old memories as he navigated his surroundings, he met up with Gerald Robotnik once more. Simultaneously, Team Sonic and their usual opponents traveled to the facility via ring portal, busting down the doors. As they separated when met by three hallways, Shadow took the infiltrators out one by one. Sonic was taken down after discovering the room Maria Robotnik lived in, learning of Shadow's deceased friend, and the cryo-pod Shadow was oftentimes placed in, comparing it to his lively hideout back in Green Hills. Eggman was omitted by Shadow, as he met Gerald when finding his Flying Eggs. Gerald revealed that he was locked in a top-secret prison for the last fifty years, including Eggman in his plan, thus forming "Team Robotnik."[2]
Infiltration into G.U.N. Headquarters[]

Gerald Robotnik's Laboratory is swallowed by a black hole
- "In exchange for my freedom, I gave G.U.N. the most powerful weapon mankind has ever seen, capable of delivering a precision strike anywhere on Earth. And our first target: G.U.N. Headquarters!"
"But firing a weapon that powerful could threaten millions of innocent lives."
"Yeah, terabyte me!" - ―Gerald Robotnik and Sonic the Hedgehog[src]
Team Sonic and Stone were tied up at the base of the laboratory, Sonic noticing Eggman and Robotnik approaching him. After Stone is freed, Shadow took the keycard, Robotnik revealing his masterplan to destroy Guardian Units of Nations Headquarters in London, England and, by extent, the whole planet, with the Eclipse Cannon, a devastating laser weapon he built attached to the Space Colony ARK. Despite Sonic's concern of the potential lost of millions of lives, Robotnik and Eggman leave for G.U.N. HQ in search of the second keycard. Shadow unleashed a Black Hole Orb, refusing to let go of Maria's unrightful death. Once the black hole breached, Tails instructed Sonic to deploy one of his rings, the ring opening in the direction Team Sonic were getting pulled into. The team observed the obliteration of the laboratory upon their escape, while Eggman and Gerald proceed to spend quality time together virtually whilst en route to London. The two visited theme parks, rode bikes, celebrated Eggman's "birthday," go trick-or-treating, celebrated Christmas and watched fireworks.

Team Robotnik arrives in London, England
Meanwhile, Team Sonic traveled to the Wachowski Residence to enlist the help of Tom and Maddie, who spent their time partaking in mind-numbing hobbies. Tails presented the plan of infiltrating G.U.N. HQ, needing the Wachowskis to implant a drive in G.U.N.'s security room to grant Tails control over the building and its forcefield, Sonic having to pass a laser hall by afterwards to enter the vault, of which all images and schematics have been wiped from G.U.N.'s database. When Team Robotnik arrived in London on Shad Thames out of a sewer, they viewed GUN HQ from afar. An impatient Shadow was calmed down by Gerald, who promised him his revenge will be exacted on an unimaginable scale. Eggman and Gerald left with Spandex Suits as Stone and Shadow were left behind in the Mecha Crab. Sonic sat atop the London Eye running out of patience, Tails asking the Wachowskis and Knuckles if they have taken their positions at the London Bridge and Big Ben respectively. Upon their confirmations, the disguised Wachowskis enter the headquarters, making their way from the reception desk to the security room's entrance. Maddie assumed Rockwell's appearance to gain access to the room, the Wachowskis remarking another drive placed by Eggman and Gerald.

Sonic leaps from Tower Bridge to G.U.N. Headquarters
The Robotniks approached the laser hall, their Spandex Suits making them impervious to the lasers. As they danced their way through, Sonic, determined to stop the Robotniks, raced through London's streets despite G.U.N.'s forcefield reactivating, visiting Abbey Road, Piccadilly Circus and Buckingham Palace along the way. Boosting up the Tower Bridge to bypass the shield, Sonic was thrown inside by Tails' aid. Sonic raced to the disabled laser hall, the Robotniks running inside the vault only to be stuck to the floor. Sonic is repelled into the air as Rockwell entered the room, revealing that it is armed with variable gravity. With Tails and the Wachowskis arrested and brought to the vault, Knuckles lept from the Big Ben and crashed through the headquarters, stealing Rockwell's control panel and accidentally busting it, complicating the tiles with variable gravity. After Sonic rescued Tails and the Wachowskis from a boulder pulled down towards them, Tom apprehended Rockwell, whom left with the second keycard. Taking it, Tom was met by Shadow, whom escaped the Mecha Crab when it was flushed down the sewer by Tails. Shadow severely injured Tom and left with the keycard, Team Sonic and Maddie attending to him.[2]
Ascension of the Space Colony ARK[]

The Space Colony ARK ascends from the River Thames
- "The Eclipse Cannon is about to turn this planet into a flaming pile of rubble. Wiping out everything in a 25,000 mile radius, including us."
"WHAT?! We can't annihilate the Earth. By combining our genius, we can rule humanity together."
"Humanity is a failed experiment. If anyone should know that it's you. All your life you've been rejected by this world. You have nothing down there. No one who cares about you."
"I have you now. We're family. We have each other."
"...Oh, Ivo, you're no Maria. The moment I lost her, my family was gone forever. The only way to give Maria's life meaning is to destroy the world that took her from me, so I'm burning it all down!" - ―Gerald Robotnik and Doctor Eggman[src]
Shadow teleported to the Robotniks, taking out the G.U.N. soldiers surrounding them, and handed Gerald Robotnik the second keycard. Shadow brought the Robotniks to the Space Colony ARK, Robotnik revealing new Nanosuits for him and Doctor Eggman to wear. As they donned their suits, Eggman was called by Stone, whom crawled onto the shore of the River Thames to alert Eggman of Robotnik and Shadow's true intentions, growing suspicion when Shadow told him Earth couldn't be ruled after they've enacted their plan as there wouldn't be anything left. Eggman scolded Stone for his suspicions and fired him, activating the ARK with Robotnik. The ARK arose from the River Thames, calling the attention of Team Sonic, Maddie Wachowski and the majority of Earth's population as it ascended up to space, numerous news stations from London, England, New York City, New York and Tokyo, Japan reporting the incident. When Tom was hospitalized, Sonic demanded the hidden location of the Master Emerald from Knuckles, Knuckles revealing it to be guarded by Wade Whipple.
Sonic arrived atop the Green Hills Sheriff's Station in Green Hills, Montana, where Whipple played hockey with the emerald. Sonic took it from Whipple, breaking it into the Chaos Emeralds to transform into Super Sonic and causing a storm as he flew upwards. The ARK deployed its Eclipse Cannon as Shadow was told to remind what humanity has taken from him, hurried charging the ARK's core with his chaos energy. Robotnik elaborated to Eggman that Shadow's charging of the core would allow for the cannon to completely pulverize the planet along with the ARK, to Eggman's utter surprise. To no avail, Eggman attempted Robotnik to combine their genius to not devastate humanity but to rather rule over them, Robotnik considering them a failed experiment that rejected Eggman. He further debunked Eggman's belief that Robotnik cared for him, Robotnik truly only focused on honoring Maria's life by destroying the world that killed her.
Shadow observes the Earth
After finishing his charging of the ARK's core, Shadow vowed Maria justice would be served when placing his hand on a window overlooking the Earth, only to notice a bright light heading towards him. Super Sonic burst through, dragging Shadow as he told him to end their feud. Shadow, convinced that he recognizes his rage and vengefulness in Super Sonic, lead him crashing into Earth where he would knock the Chaos Emeralds out of Sonic. The two rushed towards them and both assumed super forms, Super Shadow pummeling Super Sonic after their duel had engaged. Super Sonic then dragged Super Shadow in the rubble of the destroyed G.U.N. facility before repeatedly punching him across various locations on Earth, including the Rocky Mountains and Giza, Egypt. While Eggman hurried to stop the cannon's activation, stopped by Gerald, Super Shadow kicked Super Sonic into the Temple of Poseidon in Sounion, Greece. There, Super Shadow scolded Super Sonic for the abandonment of and seeming lack of care for his friends and family, Super Sonic striking Super Shadow towards the Moon.[2]
Battle for Earth[]

- "The reactor core is overloading. It's only a matter of time before it blows."
"So, what does that mean for Earth?"
"A radioactive atmosphere. Rain that kills the crops and melts your flesh. Other than that..."
"We're not done here. You try to stabilize the reactor. Buy me some time. I'll push the station away from Earth before it explodes. This is our last chance, to do the right thing." - ―Doctor Eggman and Super Shadow[src]
Shadow lost his super form as he crashed upon the Moon, followed by Super Sonic. Sonic's super form subsided alongside his hatred as he remembered not to let pain change his ways as Tom told him in Green Hills, sitting by himself disappointedly. Shadow looked at the stars above him, reminded of when he used to stargaze with Maria Robotnik atop Gerald Robotnik's Laboratory. Sonic and Shadow expressed their mutual grievances, Sonic advising Shadow to hold onto the love he felt for Maria. Shadow watched the sun rise above the Earth, reminded of when Maria told him a light shines despite the star's absence. Admitting his wrongdoings, which he did for he believed he had no other choice, Sonic forgave him, lecturing him that making the right choice is never easy. He reassumed his super form with Shadow to work together and stop Gerald Robotnik, heading towards the Eclipse Cannon while it was preparing to fire.

The Eclipse Cannon prepares to fire at the Earth
Robotnik destroyed the system controlling the fire sequence, throwing Eggman off of the Space Colony ARK's catwalk and having him fall towards Earth. Eggman was however saved by Tails and Knuckles, Eggman launching Robotnik towards the electric current left by Shadow's chaos energy. The cannon eventually fired its laser, Super Sonic and Super Shadow withholding it from impacting Earth as Eggman, Tails and Knuckles sat by the ARK's control panel. With no option to disable the cannon, Tails and Eggman decide to steer it away from Earth, the Hedgehogs protecting the planet as they do. Super Sonic exponentially succumbed to his exertion, letting go of the laser that bypassed Earth, but cut the Moon in half instead. Losing his super form, Sonic rapidly entered the Earth's atmosphere, Tails asking Knuckles if he has a ring left. Confirming that he does, Knuckles opened an escape hatch leading to Earth to throw Tails through, Tails grabbing hold of Sonic while also fainting. Super Shadow teleported next to Eggman, Eggman explaining that the ARK's core is overloading and will grant Earth a radioactive atmosphere and acid rain once it explodes. Super Shadow compelled Eggman to stabilize the ARK's reactor while he tries to push the ARK away from the Earth.

The Space Colony ARK implodes out of Earth's reach
As the two engage on their plan, Knuckles went after Sonic and Tails, grabbing the ring Tails let go of to teleport them to a cornfield. While Super Shadow, reminded of the time he spent with Maria, thrusted the ARK further, Eggman filmed a live broadcasted announcement for Stone in London, England, in which he bid his farewell. The ARK finally imploded as Team Sonic landed in the cornfield, observing the remnants of the implosion in the sky as they reflect on Shadow and Eggman's sacrifices. Shadow would however live to retrieve one of the Limiter Rings he took off to push the ARK when he was back on Earth.
Ambush at New York State Park[]

Amy Rose arrives on Earth
Sometime after Sonic was forgiven for acting on his own accord to the detriment of his friends and family in recent events, the team continued their camping activities with Maddie and a recovered Tom. Sonic also had his friends redo the race they had on his Bearthday, Sonic overshooting the goal plate this time and finding himself at New York State Park. There, a robotic doppelganger of Sonic suddenly appeared behind him with a bolt of lightning, shooting him. Sonic evaded the attack and punched the robot, only to find himself surrounded by an army of Metal Sonics. Amy Rose appeared out of the woods to destroy the robots with her Piko Piko Hammer and uncloak herself in front of Sonic.[2]
