The next morning Sonic wakes up and Amy is not next to him. Sonic gets up and walks downstairs and sees her standing at the window, staring outside with her arms crossed behind her back. Sonic says hey whatsup? Amy replies, I can't exactly explain it but I feel like something is about to happen, Sonic replies, like what? you're probably just imagining things. She pauses then says, brace yourself Sonic! All of a sudden, Sonic and Amy vanish and find themselves shooting quickly through a dark portal and when they come out the other side, they gasp at what they see. They stand on top of a mountain in a completely different world. It looked like a barren wasteland except for a big city they saw in the distance. They could see volcanoes erupting in the distance and thunder storms taking over the sky. Sonic says what the hell is this? and how did you know this was going to happen? Amy replies I didn't know this would happen and I have no idea where we are but I just felt like something was going to happen.
Meanwhile elsewhere...
Dr. Robotnik finds Purple and found out he used the chaos emeralds to power up a black vortex and turn it into a portal to try to bring Sonic and Amy from the past to their time. Robotnik sends his forces to retrieve the chaos emeralds after they flew off, as he takes on Purple. Dr Robotnik says, so you got all the chaos emeralds and tried to bring Sonic and Amy from the past to this time? well it didn't seem to work, I don't see them do you? Robotnik was the metal version of Eggman and had powerful weapons. He lifts his left hand up then a machine gun comes out and shoots at Purple. Purple takes out his double sided long sword and uses a propeller attack to block the bullets. Robotnik detaches his hand and it flew towards Purple and punched him in the face and he fell back. Robotnik used the jet pack on his back and flew towards Purple with great speed and knees him in the gut and Purple flew back 50 feet then Robotnik lifted up his right hand and a rocket came out and fired at Purple and just before the rocket hit him, a purple aura surrounded the bullet and stopped it in its tracks, Purple did a mid air back flip and landed, then looked up and saw his partner in the black robe with the black mask, using psychic powers to hold the bullet. Robotnik fires the machine gun at the one in black and he dodges but then the rocket explodes and even thou Purple was 20 feet away, the blast still sent him flying and gave him minor damage. Dr. Robotnik caught up with the one in black and grabbed him by the neck and started crushing him. Purple came up from behind and swung his double sided long sword into Robotnik's back. His armor was really strong so it only gave him a small cut, he drops the one in black and kicks both of them and sends them flying to the ground. They both land hard on their back side by side, then Robotnik takes out his most powerful weapon. This massive laser cannon comes up from his back and aims towards Purple and the one in black, laying on the ground. They both try to get up but have no luck. Purple reaches over and grabs his hand and says we only have one chance! Robotnik is powering up his cannon. The wind picks up, the cannon shoots little sparks out as its charging up that shoot into the ground and create small blasts. Purple says too late pathetic fool. Robotnik fires the charged up blast and it smashed into the ground in milliseconds and created a massive explosion that seemed to shake the earth.
Sonic and Amy feel the ground shake and they both struggle to hold their footing. The shaking stops after 15 seconds. Sonic says what was that? Amy replies we have to get out of here, quick follow me! They both run away from the direction of Purple and Robotnik and head towards one of the big mechanical cities they see in the distance. They enter the city and don't see anybody and everything seems quiet. Then they both hear something in the distance, they look up and see a ship that looked like it belonged to Eggman's fleet. Amy says what the? isn't Eggman dead? I thought Purple killed him? Sonic says Amy quickly lets hide! They duck behind the wall of a building and see the ship lower itself. It lands in the middle of the city in a big open area. Sonic and Amy watch from the distance and see robots armed with machine guns, lasers and rocket launchers. 14 of them with weapons are walking ahead while 6 of them are carrying a rope attached to a big cage, Sonic and Amy saw people locked in the cage. The robots walk into a building and the ship takes off. Sonic and Amy follow behind and sneak in after them. They follow the robots down a long hallway and they see a bright light up ahead and hear cries of pain in the distance. Sonic looks up and sees a ventilation shaft above them and says Amy, up here! He jumps up into the ventilation shaft and Amy jumps in too and follows him closely. The yelling and screaming gets louder as they make their way to the end of the shaft. They peek through the guard and look into the room and their face turns white.
