Past
Over 50 years ago, the government of Station Square hired several scientists, among them being Gerald Robotnik, to work on top-secret military weapons for them on the Space Colony ARK. Gerald in particular was put in charge of Project Shadow, a research project aiming to find the secrets to immortality. Gerald eventually succeeded in completing a final prototype for the project, but he was soon capturedand while the other ARK scientists were silenced by the Guardian Units of the Nations when they began to fear the research being done. Gerald was then taken to Prison Island in order to continue doing his research under the eyes of the government. However, despite this, he was still able to secretly get away with planning his revenge against humanity using both Shadow the Hedgehog and the Bio Lizard.

New World Saga
When other-worldly aliens such as Sonic the Hedgehog and Cream the Rabbit began showing up on the planet, many eye-witnesses and scientists began questioning the identity and nature of these beings. However, with the aid of Christopher Thorndyke and his family, Sonic and his allies were mostly able to stay hidden from the general public for a while. But when the dimension-hopping Doctor Eggman began threatening the planet with his tyranny, Sonic and his friends rose against him and thwarted his plans time and time again, earning them fast recognition as world-wide heroes.

Chaos Emerald Saga
With Sonic and his friends garnering a warm reception from the planet's inhabitants, the aliens went on to enjoy their stay on the planet. During this period of down time, Sonic and his allies visited a Savannah, went on a cruise ship across the ocean, watched Lindsey Thorndyke's recording her movies, and went camping, all while still searching for the Chaos Emeralds in order to get back to their home world. While all seven emeralds were eventually gathered together, the resulting Chaos Control did not send the aliens back to their homeworld, but rather, brought more of Sonic's world to Earth.

Chaos Saga
As a result of Angel Island being brought to Earth, Doctor Eggman soon managed to get his hands on the entity known as Chaos by studying the ancient murals of the island. Through Chaos, the doctor planned to conquer the entire planet by giving the liquid life form the Chaos Emeralds to strengthen it in power. Eventually succeeding in this scheme, in part, as Chaos would betray him soon after transforming, Perfect Chaos was born and began doing on a rampage across Station Square, and furthering threatening to destroy the entire planet. With the positive feelings of Sonic and his friends Sonic the Hedgehog transformed into Super Sonic and neutralized the negative emotions within Chaos, both calming him down and saving the world.
