3 weeks after Sonic and Amy's battle with Purple, Sonic and Amy pass out together on the couch. Sonic is woken up early the next morning because Amy was tossing and turning. Sonic looks down at her and noticed how different she looked, she was purple instead of pink, had dark blue clothes and longer hair, her 3 front strands of hair were gone from Purple chopping them off in battle and she had a scar on her left eye. Sonic nudges her and she wakes up. Sonic asks did you have a bad dream Amy? she replies I can't remember my dreams...she gives Sonic a hug then slowly gets up. Sonic says are you ok to stand? Amy slowly starts walking forward then stumbles back and sits on the couch. Sonic says hey take it easy, you took a beating. Amy pauses and looks down at her feet. Sonic says Amy that was amazing how well you did against Purple, I can't believe you actually broke his sword and almost finished him! Amy looks up and smiles then pauses and says hey, wheres my hammer? Purple kicked it through that building window...Sonic points over to the corner of the room and Amy saw her staff standing up against the wall. Sonic says don't worry, I grabbed it for you while you were out. Amy replies thanks Sonic.
A few days go by and Sonic trains with Amy using a sword against her staff. Amy keeps getting better and better every day. By the 3rd day, Amy was actually able to out match Sonic with her double sided spear. Because Amy was still purple, she had more power than Sonic in his original form. After Amy knocking the sword out of Sonic's hand and besting him, they walk inside and sit down on the couch. Sonic says wow Amy, those new powers of yours are impressive. Amy replies my teacher told me it wont last forever thou...to be honest I'm not even sure why I didn't lose my powers after getting beat and put into a coma. Sonic pauses for a moment. Amy turns the TV on and sees Purple's remaining forces attacking one of the big cities. The people of the city are asking for help from the 2 heroes that saved them from Purple and Eggman nearly a month ago. Sonic says I don't think I even need to ask if you're ready for this with how you kicked my ass moments ago. Amy grabs her staff and says lets go! Sonic grabs his sword and they both run full speed towards the city.
Sonic and Amy are seconds away from the city and Sonic is in disbelief with how fast Amy was. He could tell she was actually slowing down a bit to match his speed. They look ahead and see the city under attack. They could make out one of Purple's massive air ships shooting down buildings one at a time while robot forces with swords, spears and stalves were attacking the police force of the city. Amy dashes ahead of Sonic and turns her staff into the hammer and starts smashing robots to pieces. Sonic runs in and starts slashing robots in half. After 10 minutes and slaying the entire army of robots, the ship drops off one more robot then turned the other way and flew off. Amy yells get back here! Sonic says Amy don't worry about it, lets just finish off this last robot and save the city. The robot lands on the ground 20 feet away from them and takes out a double sided spear. This robot looked a little more tough than the rest of them but Amy turns her staff into the hammer and says I've got this Sonic. Amy ran towards the robot and did her hammer ground pound and flew into the air and after 3 front flips, she turned her hammer into the double sided spear and swung at the robot. The robot blocks with its spear then starts dueling with Amy. After a few minutes of them dueling, the robot elbows Amy in the face and she gets mad then swings her double sided spear and cuts one of the robots legs off then kicks it and sends it flying. The robot lands on its back and tries to get up but cant do it. Amy turns her staff into the hammer then walks up and holds her hammer back, then with a mighty swing, she crushes the robot. The people who came out of hiding and the police force thank Sonic and Amy for their help.
Sonic and Amy run back home and once again, Sonic struggles to keep up with Amy. Amy slows down again and says sorry Sonic, I guess I should go easy on you? Sonic chuckles and replies you're just lucky I'm not Super Sonic right now. Amy replies haha I know. Minutes later they get close to their place and see it in the distance. They both slow down and start walking, Sonic puts his arm around her shoulder and she smiles at him. They make it inside and head upstairs and go to bed. Sonic and Amy fall asleep in each others arms.
