Sonic, Shadow and Knuckles were the only ones who managed to avoid Eggman's attack on the city. The others had been kidnapped, but the doctor's plans for them were unknown. Everyone was gone; Tails, Amy, Cream n' Cheese, everyone.
Sonic and Shadow had been called to an "emergency mission" during Eggman's attack and Knuckles was on Angel Island, guarding the Master Emerald, as he had done for decades. He was the first to discover the empty city, as he had decided to pay his friends a visit, after all he hadn't seen them for 3 years. Shortly after Knuckles had searched, pretty much, most of the city for any trace as to what had happened, Sonic and Shadow returned. The echidna explained what he had found and, after Sonic had explained their absences, guessed that their "mission" was a diversion from Eggman, so that he would have no trouble in his capturing of the city.
"That bastard! Why would he do this?" Sonic exclaimed, clenching his fists with hatred and anger.
"He must have one big plan up his sleeve." Said Knuckles
Shadow folded his arms. "Must be a huge plan if it involves capturing an entire city of people," he said.
"I don't know what he's up to but whatever it is he has our friends, and the whole of Emerald City in danger," Sonic exclaimed, "We have to help them!"
"Yes Sonic we know but the thing is, we have no idea where he's taken them!" Shadow pointed out. "Where could his base be?"
Sonic pondered over this question. Eggman hadn't been heard from in a while so this attack wasn't expected at all. Usually the doctor took pride in his plans and showed them off to the world. The last time he was seen was 3 years ago, the time of the ARK incident. Sonic had saved Shadow from falling to the Earth, whilst fighting the Ultimate Life Form Prototype, and saving the planet. The two had settled their differences and joined together as a team.
"Umm…Hello? Sonic?"
"Oh! Sorry Knuckles. Got lost in my head there for a sec!" He suddenly remembered Tails' latest invention.
"I've got it! We gotta go to Tail's workshop!"
