Then, a large figure appeared in the night sky. "What is that?" Bubbles yelled nervously. Tails and Sonic stopped in their tracks and their jaws dropped. "It can't be, no, please tell me that's not what I think it is Sonic," Tails frantically yelled at his best friend. Sonic, still frozen, replied "That's exactly what you think it is Tails." The girls were confused, they had no idea what was going on. "Are you guys going to fill us in or are we just going to have to figure this out on our own," Buttercup screamed obviously annoyed. Before the boys had time to answer, the figure landed in the park. It was a giant egg shaped ship. Out of the ship walked a large man who was also shaped like an egg. He was wearing a red coat, black pants, and sunglasses. He had a giant mustache and was the ugliest person they had ever seen. "So it's true, you two did escape from Mobius after the bombing. I thought I had killed everyone. My mistake. You may have lived through my bomb 11 years ago, but I promise you that you will die tonight," the man exclaimed with an evil smirk on his face. The girls finally understood who this villain was, it was Dr. Eggman, the person responsible for the murders of everyone on Mobius. "I will take care of Tails and Sonic myself, but I have a couple of friends who are dying to get their hands on the Powerpuff Girls." The next thing they knew, a dark colored pony with dark green eyes, fangs, a twisted horn, and insect like wings emerged from the ship followed by someone they all knew….Dark Fluttershy. "Fluttershy? Why are you doing this? How could you bring Dr. Eggman to Townsville after everything I told you about him," Tails yelled. Fluttershy just laughed evilly and shook her head. "I told you you would regret breaking up with me Tails. We were perfect together and you dumped me for some dumb little girl. Well, I bet you are sorry now. I am going to kill your little girlfriend while you watch. My friend Queen Chrysalis here is going to take care of her stupid sisters. Hope it was worth it."
Tails looked around at his friends. He loved them all so much, he had to protect them. He got into his fighting stance. Sonic and the girls followed his example. Blossom counted to three and they attacked. Tails and Sonic took on Dr. Eggman, Bubbles started fighting Fluttershy, and Buttercup and Blossom rushed towards Queen Chrysalis. Dynamo was taking care of the remaining members of the other groups. Though there weren't as many people to fight, these enemies were way stronger and the Powerpuff Girls, Tails and Sonic were losing. Tails looked over at Bubbles and saw that Fluttershy had her pinned to the ground and was trying to choke her. Queen Chrysalis had her sisters bloodied and on the verge of tears. Sonic and Tails were doing alright with Dr. Eggman, but they were getting tired and they didn't have the strength to defeat him and rescue the girls. All of a sudden, a loud voice interrupted the fight. "Leave them alone you stupid egg. You've caused enough damage in your life, it's time to pay for what you've done." Out of the darkness, a black and red hedgehog appeared. "Shadow?" Sonic yelled. "You know it bro. No time to explain now, just trust me," the mystery hedgehog said. Then, he pulled out a giant bag and scattered 7 emeralds onto the ground. "Noooooooooooo, who are you and how did you get your hands on my chaos emeralds," Dr Eggman screamed. His face was red and his voice was shaking with anger. As Dr. Eggman ran towards the hedgehog, the emeralds rose up completely on their own and started spinning. As they were spinning, the grew and finally combined to form one giant emerald. "Everyone, over here quick," the hedgehog yelled. Tails, Sonic, and the girls fought off their attackers and ran towards him. When they reached the emerald, he instructed them to join hands. As they did, they were lifted into the sky and started spinning just like the emeralds had moments before.
