Sonic the Hedgehog: Genesis Era
How It All Came Together
Okay, all I'm doing here is doing a loose summary of how I think the pre-Adventure games are linked together given that they are often very confusing to figure out and I don't think there's a canon timeline. Also a lot of them are contradictory, so I'm going to do my best to tie it together while maybe having to change a few things (like that eight Chaos Emerald in Sonic the Fighters). So...yeah. More a plot summary of a fanfic that may never be written than an actual fanfic. I hope you guys enjoy it anyways.
Sonic the Hedgehog
Everything had started simply enough. The world was hardly in a state of peace, but it chugged on as best as it could despite the atrocities committed throughout the land. South Island in particular seemed to be separated from the minor chaos of the land, and was home to a variety of animals who managed to co-exist with each other. It was hardly a utopia, but they were happy.
The disappearances began slowly. A few animals here and there went missing and were presumed lost or even killed in an accident. But the number of missing animals began to rise higher at an alarming rate. Eventually a new type of being descended on South Island; a small army of robots. They tore through the land in search of something while taking every opportunity to kidnap small creatures to send back the their home base. With every captured critter came another robot soldier; they were being used as an energy source. But to what end? Just what were they after?
Sonic the Hedgehog didn't care what they wanted. All he knew was that they were taking advantage of his friends and neighbours, and he wouldn't stand for it. Using his remarkable speed and natural spiked body, he discovered he could destroy the outer shell of the robots and free the animal within. And he set about doing just that against the baffled robot army. Eventually this led to the arrival of the leader of this robot army; a human scientist known as Dr. Robotnik. Furious to see something taking down his army, he tried to take on Sonic himself through the use of mechanical vehicles. In the end, however, he simply wasn't prepared for someone of Sonic's skill and speed to fight against him; the doctor was forced to retreat.
And yet Sonic still had no idea what Robotnik's true motives had been...
Tails Adventure
As Robotnik assaulted South Island, there was a certain disaster unfolding on another island as well. The twin-tailed fox known as Tails (born "Miles Prower") once lived on Cocoa Island and spent his days tinkering away on gadgets. The island was inhabited mostly by birds, but the fox was nonetheless happy to be there. But just as Robotnik descended on South Island, a different group of villains had set their eyes on Cocoa Island; the Battle Kuku Army. Made up of a astounding number of bird soldiers, they claimed their intention for a gem known as the "Chaos Emerald" which was apparently hidden on the island.
Though Tails knew little of the emerald, he was more than ready to defend his home. Not to mention getting his hands on the Chaos Emerald would probably give him a bargaining chip against this army. Armed with a variety of tools that included bombs and a remote-control robot, the fox fought back against the surprised invaders. It was far from an easy battle, but the fox eventually came to discover the Chaos Emerald and beat back the bird armada. But he knew that as long as he stayed on Cocoa Island with the Chaos Emerald, more people would certainly come to track it down. In order to save the island, the fox decided it would be best to move somewhere where he could better fend off attackers.
Hearing of the events that had unfolded on South Island and the heroic acts of one Sonic the Hedgehog, Tails decided the hedgehog would make for a great ally in defending the gem. And so the fox found himself on South Island, becoming fast friends with the hedgehog.
