Eggman had a new army attacking a large city. 3 massive air ships firing at the buildings and robots with weapons killing people and chasing some out of the city. A black hedgehog with short hair who was only a bit smaller than knuckles, appears out of nowhere on the deck of Eggman's main ship. Eggman sends a few robots after him, A purple aura surrounded him as he lit up a black vortex and sucked 2 of them in, the other with the sword came at him and he took out a double sided long sword and sliced the robot in half and it exploded. Eggman sends out a dozen more and he disposes of them in a matter of minutes. He shouts out, is that all you've got? You attacked my city so you better be able to do better than that! A small robot flew into the sky and a big screen pops up with Eggman's face. Eggman says ok if that's what you really want, you've got it! Eggman sends out a single robot, it looks different from the others and has silver armor. The black hedgehog says, you've gotta be kidding me, that's it? The silver robot flew at him and takes a swing at him, he barely manages to dodge the attack. 15 minutes into battle the black hedgehog has the slight upper hand until he powers up with his purple aura, then the silver robot dodges an attack and gets close and saps his powers. The silver robot jumps back then a purple aura lights up and its eyes turn purple and start to glow. The black hedgehog lost most of his power but continues to fight. He takes out his double sided long sword and starts swinging at the silver robot. The silver robot lights up its purple aura then disappears and keep dodging his attacks. The silver robot reappears and kicks him in the face and he drops his double sided long sword and goes flying through a building and the building collapses. The silver robot grabs the double sided long sword and hovers down trying to find him in the ruins of the building but hes nowhere to be seen.

Sonic was off collecting the 7th and final chaos emerald, meanwhile way up on a mountain top, Eggman's new forces were attacking Knuckles, Tails and Amy, who had just grabbed the 6th chaos emerald. Knuckles smashes half a dozen of them into pieces as Tails narrowly manages to dodge the weapons of 2 others. 4 of them close in on Amy and she backs up closer and closer to the steep edge of the mountain. Tails yells, Amy look out! A robot swings a sword at her and she slips backwards and falls off the mountain side. Knuckles destroys the rest of them and they look over the edge. Its about an 80 foot fall. Tails says oh no! Amy! Knuckles says Tails there's nothing we can do, we have to get out of here now, before a lot more of them come back.
Sonic meets up with Knuckles and Tails later that day after getting the last chaos emerald and they give Sonic the bad news. In a rage, Sonic grabs all the emeralds and transforms into Super Sonic and flew off to go after Eggman. Super Sonic arrives in the city where Eggman's main ship had been attacking. He smashes through 50 robots who were attacking people on the streets then flew up to Eggman's ship and smashes threw the windshield and lands in front of Eggman. Eggman begs for mercy and claims he never intended to kill Amy. Super Sonic slowly walks towards him as Eggman pleads to Sonic. From behind, one of the golden robots snuck up on him and injected Sonic with a knock out serum. Super Sonic passes out and returns to normal. The chaos emeralds hover upwards and just before they fly away, Purple appears out of nowhere and creates 7 small black vortexes in front of each emerald and catches them as they try to fly off. Purple hands the chaos emeralds to Eggman and Eggman says good work you 2! Now kill him! The golden robot swings its double sided spear towards Sonic and Purple blocks with his double sided long sword he stole from the black hedgehog. Purple says wait, I've got a better idea. How about we lock him up and make him watch us kill all his friends, Then we kill him? Eggman has a big evil grin on his face. I like it! lock him up! Later that day, Eggman designed a prison for Sonic located underneath a big lake. Purple kept Sonic sedated until he moved him from his smaller prison to the one under the lake. Purple and Sonic enter the prison. With Sonic still passed out, Purple says now's my chance, but I have to do this quick. His purple aura and eyes lit up and he placed his hand on Sonic's chest. A bright flash happens then Purple's aura dies down and he says, that should do it. He puts Sonic into an electrical field, sets up the big screen on the wall for Sonic to see, then flew out the prison and locks the entrance at the top. Purple shoots up through the water then flew off.
Amy woke up in a bed in an unknown house with a massive headache and her whole body in pain. The black hedgehog walks up to her and says, good to see you're awake. Amy asks who are you? He tells her about his battle with Eggman and Purple and also tells her Sonic has been kidnapped and Eggman has the chaos emeralds, the others will not be able to stand up against his forces so I will train you and help you to fight against them. Amy heals in a couple days and starts her training.

After another week of training with weapons against her teacher she learns to use her hammer a lot better and also learned to use a staff and a spear. Her teacher says good job Amy, take this new weapon, you've earned it. She gets her staff with the hammer and double sided spear option. Her teacher tells her now that you're a lot faster and more skilled with a weapon, I will teach you my magic powers and your training will be complete and we'll go save Sonic from his prison and help your friends defeat Eggman and that purple robot. Amy says sounds good to me! Her teacher tells her to focus, Amy focuses and all of a sudden she sees a vision of 7 chaos emeralds sitting in Eggman's main ship being guarded by a bunch of robots. Amy's teacher says good job, that was quick! From now on, any time you need to find the chaos emeralds you'll be able to see it in your mind where they are. Amy says, that's amazing! Her teacher says ok now try this one. I want you to focus on creating an aura. Before Amy tries to do it shes interrupted by a loud crashing sound outside. They both run outside and see a giant tree had fallen over. From behind the large stump, Purple jumps over and confronts Amy and her teacher. Purple has his double sided long sword and Amy's teacher takes out his axe. After a couple minutes of them taking swings at each other, Amy's teacher vanishes and reappears behind Purple and kicks the double sided long sword out of his hands then swings his axe at Purple. He misses and it gets stuck in the ground. Purple kicks him in the face and he flew through the air and broke a large tree in half, on impact. Purple grabs the axe from the ground and walks over to Amy's teacher. Amy turns her staff into the hammer and jumps through the air to attack Purple. Purple quickly back kicks Amy and she flew into the house, smashing it into pieces. Amy's teacher is still laying on the ground unable to move. Purple takes a mighty swing at him and cuts his body in half. Amy softly moans, no...Purple drops the axe and picks up his double sided long sword and walks over to Amy laying there in the broken down pieces of the house. Purple stood only 5 feet away from her and looked down at her for a few seconds, then his eyes flashed and he flew off, leaving Amy there.

Amy had a dark cloak on with a dark cloth covering her face and her new weapon on her back. After her teacher was killed she decided instead of regrouping with everyone, she'd go looking for Sonic and do her best to hide from Eggman's forces. Amy is in a deep forest and tries to focus and locate Sonic. She gets frustrated when it doesn't work, then all of a sudden she sees a small robot fly above her through the air and above the trees. She wants to know why its by itself and where its going, it seems to be carrying something small. The small robot was flying quickly through the air but with her new and improved speed, Amy easily keeps up. 45 minutes later after chasing it she sees it fly over a lake and she watches it from a distance. It flew down towards the lake then stopped. It drops the small package through a small pipe sticking out of the water. The robot then flew off. The robot had dropped a small amount of food and water into Sonic's prison just enough to keep him alive. Amy watches it fly away then thinks, that's weird. Maybe this has something to do with Sonic. She focuses hard and for a split second, she sees Sonic trapped in the prison under the lake. Amy runs around the lake looking for any way to get to Sonic. She also tried swimming underwater but couldn't dive deep enough to reach the prison. After hours go by, it gets dark and Amy eventually gives up and runs off and finds a beaten down house about a kilometer away. She finds an old bed and sits on it. She starts thinking about how hopeless things are. Even with her training, she has no idea how to help Sonic. A tear came to Amy's eye and she lay down and fell asleep.
