The three main characters of Sonic game namely Sonic, Tails, and Knuckles are incidentally alerted by robots from a place called Meteor Tech, as they start attacking cities around the world, starting with Megalo Station. They settled a party to retrieve the legendary artifact called "Ark of the Cosmos", an item that has the ability to control gravity. On their journey, they are discovering lots of surprises, including the Babylon Rogues, its a group of avian thieves who are also after the Ark of the Cosmos. This issue sets off a war between who gets the artifact, now leading them to settle their dispute by having an Extreme Gear competition. At the end of the game, it is revealed that the Ark of the Cosmos together in Babylon Garden will form a black hole. So the Babylon Rogues and Team Sonic go to stop the black hole, leading to the ending where Team Sonic are exiting Megalo Station, where Jet appears to challenge Sonic of course in a race. The game ends with those two racing in the city.
