Sonic and The Cooper Gang carried Carmelita into the safehouse. Outside, Tails, Knuckles, and Amy saw Sonic with The Cooper Gang. Tails knocked on the door. "Someone found our safehouse," Murray panicked. "I'll see who it is," Sonic said. He opened the door and saw his friends. "Guys!" They shared a group hug. "Who is it Sonic," Murray asked. "It's my friends, Tails, Knuckles, and Amy!" Tails then noticed Bentley operating on Carmelita. He walked over to see what was going on. "What happened to her?" "She was turned into a robot and got badly damaged. I may not like her personally but I never wanted this to happen to her." "I can help rebuild her." Tails got to work and helped Bentley repair Carmelita. Sly was pacing back and forth. He couldn't imagine living without Carmelita. "Please let her be alright," Sly begged. "She'll be fine Sly. Carmelita is the toughest woman I know," Murray said. "Eggman is here as well. He's teamed up with someone called Dr. M. I think they're looking for the shards of the paradox prism," Sonic said. "What even is the paradox prism anyway," Sly asked. "It's an energy crystal with limitless power. If Eggman and Dr. M get the shards and rebuild it, they'll be unstoppable," Tails answered. "Then we need to make sure that doesn't happen," Bentley said. Tails and Bentley finished repairing Carmelita. Everyone gathered around her. "Is she," Sly started to ask. Carmelita opened her eyes and sat up. Sly gave her a hug which she returned. "Aww," Amy said. "Who are they?" Tails, Knuckles, and Amy introduced themselves to Carmelita. Meanwhile Eggman and Dr. M located another shard and went to collect it.
Back in Green Hill, Tails was trying to locate Sonic. "Any luck Tails," Amy asked concerned. "Actually yes, he's in another universe. When he shattered the paradox prism, he must have been sent there. I'll open a portal." Tails grabbed a ring and used it to open a portal to Sly's world. Tails, Amy, and Knuckles jumped through. Sonic and The Cooper Gang were chasing after Eggman and Dr. M's airship. "I didn't know that this van could fly," Sonic said. "I've installed many technological advances," Bentley said. "You remind me of my friend Tails. He's a genius just like you." "Aww thanks for calling me a genius." They caught up to the airship and Sonic and Sly jumped in. "Intruder Alert!" Sonic and Sly turned to see the newly robotic Carmelita leading an army of robots. "Carmelita? What did they do to you," Sly asked sadly. "My name is CF-5!" Sonic battled the robots while Sly tried to reach Carmelita. "Carmelita, I know you're still in there. You wouldn't allow any robotics to change you." Carmelita struggled to break free of Eggman and Dr. M's control. "Keep fighting Carmelita, I know you can do it." Carmelita fell to her knees while holding her head. She then stood up and stared at Sly. "Carmelita?" "I'm back Sly," Carmelita then turned to Sonic. "Is there to reverse this?" "Yes, I'll see if I can deroboticize you." "I don't think so." Eggman and Dr. M showed up in a giant mech. Sonic, Sly, and Carmelita fought Eggman and Dr. M. During the battle, Carmelita made good use of her robotic advances and even commented on how cool they were. Unfortunately she took some severe damage. Sly ran to check on her while Sonic forced Eggman and Dr. M to retreat. "Is there anything we can do for her," Sly asked. "I think we can revive her but deroboticizing her is not an option at the moment," Sonic answered. Sonic and Sly helped Carmelita to the van. Bentley and Murray gasped as they saw the badly damaged robotic Carmelita.
Sly and Carmelita met with Bentley and Murray. "What is Carmelita doing here," Bentley asked. "She's going to help us collect all the shards to the paradox prism," Sly answered. "I'm thinking that it will help Sonic find a way back to Green Hill," Carmelita said. "Okay but I've got my eyes on you so don't you dare try to pull anything on us," Bentley warned. "You have my word. We'll work together to help Sonic and then it's back to business as usual," Carmelita said. "I can work with that," Murray said. Meanwhile Sonic was sitting on a rooftop, thinking about his friends back in Green Hill. "Don't worry guys, I'll find a way back home I promise." He then saw an airship and robots started to flood the streets. Sonic sprang into action and started to take out robots right and left. Soon Sly, Bentley, Murray, and Carmelita showed up and helped Sonic defeat the robots. "Attention people of this world, I Dr. Eggman and soon enough me and Dr. M will be your new rulers." "That will never happen Egghead," Sonic shouted. "So you're here too Sonic. I should have figured that you'd be around here somewhere." "Look I don't know who you are but you're messing with the wrong gang of criminals," Sly said. "Oh we'll soon deal with you Cooper," Dr. M said. Suddenly a robot grabbed Carmelita and flew back to the airship. "CARMELITA," Sly shouted. "We'll get her back I promise," Sonic said. "Yes we will," Sly said. Carmelita was placed into the roboticizer and roboticized. "Help us locate the next shard," Eggman ordered. "Yes Master Eggman," Carmelita replied.
Sonic and Carmelita left Interpol but saw no sign of The Cooper Gang. "You have experience with them. Where do you think they would be," Sonic asked. "Knowing them, they're probably long gone by now," Carmelita said miserably. Sonic would like to help Carmelita but he needs to figure out a way to back to Green Hill. "I'll keep my eyes out for them but I really need to find a way home." "Alright." Sonic dashed off and Carmelita turned to see Sly walking out of the shadows. "Got a new friend Carmelita," Sly asked. "That's none of your business Cooper! Now you're going back to jail!" Carmelita pointed her shock pistol at him. However Sly quickly knocked it out of her hands. "Ya know Bentley found out about some sort of magic energy shard. I thought you should know about that." "Sonic mentioned something about a magic energy crystal that he destroyed. He said that it was called the paradox prism." "Maybe if we find all the shards, we'll get some answers." "As much as I hate to agree with you, you're probably onto something. Maybe collecting the shards will help Sonic get home." "Glad you're on board." Meanwhile Dr. M found the shard and felt a powerful energy from it. He took it to his lab to experiment on it. A portal opened up and Dr. Eggman walked out. "Who are you," Dr. M asked. "I am Dr. Eggman and I see you have a piece of the paradox prism." "Paradox prism? So that's what this thing is." "Yes, I was going to use it's energy to take over the world." "Perhaps we could work together. Two evil geniuses is better than one." "I like the way you think Doctor?" "Dr. M."
