Earth

*"This world is on the far side of the universe. You should be safe there."
"I don't want to go without you!"
"You must."*
―Longclaw and Sonic the Hedgehog[src]
**Earth** is a planet in the universe, and the third planet in the Solar System. It is primarily inhabited by Humans and contains a small amount of alien immigrants, whom are anthropomorphic and colorful versions of the usual animals on Earth.

## History

### War for the Master Emerald

*"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]
Because the Echidna Tribe caused havoc and chaos with the mystic Master Emerald, Owls swore to protect it by hiding it on planet Earth, building a labyrinth nearby Hawaii, and hiding a compass to it in Siberia.

### Sonic's New Life

*"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]
Although having formerly lived on his own planet, Sonic was forced to leave it regarding the Echidna Tribe's attack. He was guided to Earth by Longclaw, a planet far away from Sonic's. He had to unfortunately say goodbye to his caretaker Longclaw.

But, ten years later, Sonic would become attached to the town of Green Hills and its inhabitants, in which he would play with them and watch their actions as they remained unbeknownst of Sonic's existence.

### Green Hills Energy Surge

*"Twenty minutes ago, an energy surge knocked out power across the entire Pacific Northwest. What do we know?"*
―Sam Walters to the United States army[src]
After viewing the playoffs, Sonic decided to play a baseball match of his own. Winning at his own game, Sonic holds his hand up, expecting a high five, but then he remembers that he is unknown to everyone and he explodes a massive electromagnetic eruption upon the entire Pacific Northwest, granting the area a total blackout and the disablement of a satellite. This causes the United States Armed Forces to come to the conclusion of contracting Ivo Robotnik to investigate the anomaly that has happened in Green Hills. Said doctor finds out what caused this is a creature unlisted in Earth's animal kingdom.

### Chase of San Francisco

*"You're not allowed up there! It's one of the Seven Wonders!"*
―Ivo Robotnik to Sonic the Hedgehog[src]
Confronting Sonic in San Francisco, Robotnik pursued Sonic as he deployed rings leading to various well-known locations, almost injuring a mime and a family in Paris, France, racing atop the Great Wall of China, and damaging the Great Pyramid of Giza in Egypt.

#### Robotnik's Banishment

*"Guess what, Eggman? I'm not leaving Earth. YOU are!"*
―Sonic the Hedgehog to Ivo Robotnik[src]
After a race around the world, Sonic battles Robotnik, eventually sending him to another planet with a ring. Sonic, as a reward, gets to stay on Earth with his newfound Wachowski family.

### Founding of the Guardian Units of Nations

*"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."*
―Sam Walters to Maddie and Rachel[src]
Following the Chase of San Francisco, Commander and Vice Chairman Sam Walters founded the Guardian Units of Nations, a federal organization determined to rid Earth of potential alien threats.

### Sonic's World Trip

*"This one time, I couldn't decide where to go. So I figured I would just see it all. It helps when you're as fast as me."*
―Sonic the Hedgehog[src]
Sonic traveled around the world, visiting states, countries and cities in North America, Africa, Oceania, Asia and Europe.

### Knuckles' Arrival

*"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]
After Doctor Eggman launched a chaos energy wave on the Mushroom Planet, Knuckles the Echidna saw it and met Eggman, partnering with him to fend off his enemy Sonic the Hedgehog on Earth, who he has been searching for since the death of his tribe members.

### Tails' Arrival

*"...And then a signature coming from some backwater planet called... Earth?!"*
―Tails[src]
Having observed the Green Hills Energy Surge, Tails would track Sonic's energy signature down to Earth. He'd go to Sonic's exact location while Eggman and Knuckles threaten him at the Wachowski Residence. Tails saves him and escapes Knuckles, hiding in Wade's garage and learning of the Master Emerald there.

### 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 travel to Siberia, taking shelter in a bar where they must take part in a dance battle before meeting Knuckles and Eggman in a cave when acquiring a compass for the emerald. Sonic escapes them by having Tom teleport them to Hawaii, later running towards an island nearby, where his enemies are able to unveil the Labyrinth in which the emerald is based.

#### Duel at the Master Emerald Shrine

Sonic and Knuckles fought by the Master Emerald Shrine while Eggman steals the emerald, destroying the Labyrinth when teleporting to Green Hills. Sonic and Knuckles saved each other, making amends on the island and are rescued by Tails' *Tornado*.

#### Battle Against the Giant Eggman Robot

*"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, only to see a giant storm in the midst of the town, unveiling a Giant Eggman Robot destroying the town. The three manage to take it down, forming a team that protects the Master Emerald and celebrating with a baseball match at the Green Hills Baseball Field.

Afterwards, the Guardian Units of Nations would investigate the area for signs of Eggman, who seems to have died. An agent reports that they found a file in their database regarding Project Shadow as Shadow's capsule opens in a secret research facility.
