Sonic, Sally and everyone else was gathered at meeting room within Knothole as they were gathered by Nicole as she tells them that Y/n disappeared and she's not able to track him anywhere on the planet which shocked everyone as Vector ask.

Vector: So you get to tell us that Y/n just vanished!?

Nicole: That's correct. I try to find him but I couldn't locate him, his last location was a New Metropolis Park and his singal was gone.

Espio: That is strange. How did he disappeared all of a sudden.

Amy: Maybe he's captured.

Sally: I agree but without his location, we don't know who or where he is.

Sonic: Still we can't just give up. We just got him back twice and we are not gonna lose him again. I refuse to lose Y/n after everything he did for us, we got to find him somehow.

???: I think I know where he is.

They turn and they were surprised to see another Sonic but wearing unknown police armor as he took off his helmet and they were even more shocked to see he looks exactly like Sonic.

Knuckle: (shocked) Another Sonic?!

Tangle: (shocked) But he's not Metal Sonic, in fact, he looks exactly like Sonic in every way.

Zonic: This may surprised you all but let me ensure you all that I'm from a different dimension. My name is Zonic, I'm a zone cop or interdimensional police officer.

Tangle: (surprised) Whoa! So your like a dimension police cop! That's cool!

Sally: Why are you are?

Zonic: I'm here because i know what happened to your friend. He's been taking to Anti-Mobius.

Sonic: And that is?

Zonic: Allow me to explain.

He pushes a button on his wrist and shot out a hologram of multiple universes which amazed everyone while Zonic explain.

Zonic: There is different dimensions or zones that have its own Mobius and their own good and evil. Except esch universe has a different take on the world each universe lives on. For example: There is a universe where the gender is swapped or there is a universe where the freedom fighters her humans while Eggman and his army are Mobian.

Sonic: (smirk) Is there a universe where I became king of Mobius?

Zonic: Actually yes. Everything you think of does exist in each different universe. However one universe is where Y/n is taking and we call it Anti-Mobius.

Sally: Why calling it Anti-Mobius?

Zonic: Because in that universe, heroes and villains are swapped. What I mean by this is that Sonic and the others are the villains of their own universe while Eggman is the good guy.

Rouge: Huh how interesting.

Shadow: So what's their business with Y/n and why they taking him to their universe.

Zonic: There is talks about a plan that involves costing destruction in all universes and they believe Y/n's is their ultimate plan to succeed.

Sally: So what should we do?

Zonic: My objective is to stop them before their plan will succeed. At first I was gonna warn Y/n myself but I arrived too late. Now I need to travel to Anti-Mobius to save him before their plan will succeed.

Sonic: Let us come with you. Y/n is our friend and I failed him once, I won't fail him again.

Tails: Same here.

Zonic: Very well then, but I can't take a lot of you, only five of you.

Sally: Me and Nicole will assist.

Tangle: (smile) Me and Whisper will also come along.

Amy: Me too.

Zonic: Alright then, hope you all area ready, Anti-Mobius is not a friendly place.

Sonic: (smirk) We'll always ready, let's do it, to it!

Zonic pulls out a gun like devices and fires a opens a portal which he, Sonic, Sally, Amy, Tangle and Whisper enter through the portal and once through the portal closes as they head to Anti-Mobius to save Y/n.

(Later)

A portal opens in a alleyway as the five came out of the portal and once out the portal closes behind them as Zonic check his wrist devices as he tells them.

Zonic: We've arrived, now be careful. This world ain't the world you've used to back in your universe.

Sally: Understood.

They leave the alleyway and they were shocked to see nothing in a abandon village as they walk through the abandon village as Sonic ask.

Sonic: Where is everyone?

Zonic: Either hiding from Scourge's wrath or hid gang he has.

Sonic: Whose Scourge?

Zonic: He's Anti version of you. Apparently he changed his name for some odd reason but either way, he is you bit evil.

Sonic: Huh. So we each have their own Anti versions of ourselves?

Zonic: Yeah but not only that but your personality is also different as well. For example Anti-Amy is a crazy person who loves to break people's body parts.

Amy: (scared) Jeez that's scary.

Zonic: And there is Anti-Whisper who is extremely loud.

Whisper: Kinda figure that.

Tangle: So where do you think they are keeping Y/n?

Zonic: Possibly their capital building. Hopefully we don't ran into anyone on the way.

???: Hey you there!

Suddenly a gain of Anti-Mobians appear out of nowhere and surrounded them while three familiar figures appear and they were shocked to see Vector, Espio and Chamry but they were wearing green jackets with Vector wearing sunglasses.

Sonic: Vector?

Zonic: No. That's Anti-Vector and his gang. In this universe, Anti-Vector is the leader of a Gang and rob and steal anyone who comes by here.

Anti-Vector: (smirk) You have some guts coming into our territory like a normal day.

Anti-Espio: (smirk) Enough talk, I wish to shoot them right here and right now.

Anti-Charmy: Shut up and let the boss handle this unless he can't.

Anti-Vector: Oh shut up the both of you! Now, hand over all of your money and cone with us!

Sonic: (smirk) Sorry but no thanks but nice to meet you anyways.

Then Sonic dashes over and spin dashes Anti-Vector, sending him flying while Anti-Espio try to shoot him with his guns but Tangle wrapped his arms with her tail and pulled him towards her and punch him and then the other gangs charge towards them which cost a huge fight to happen.

Zonic pulled out his pistol and fired electricity at them, knocking them out cold as he roll away from the attacks and fired a few more electricity shocks while Amy swings her hammer around and hitting Anti-Charmy away and after a while they managed to beat up Anti-Vector and his gang as they lay on the ground unconscious as Sonic clap his hands together while he said.

Sonic: (smirk) This is going to be too easy.

Zonic: These are just Scourge's weaker gang, close we get to the capital, the stronger each gang members are.

Sally: Even if this is a different universe, is it a possible the layout of Mobius is the same?

Zonic: Perhaps so.

Sally: Nicole, pull me up the map of Mobius.

Nicole shows Sally the image of Mobius as she look at it and then says to everyone.

Sally: If I am right and I hope I am right, the capital could be Metropolis so I think we should take North and see what we can find.

Sonic: (smile) Understood. Hang on there Y/n, we're coming.

(Meanwhile)

We see a unconscious Y/n laying on the floor of a cell as he slowly let out a groan while he slowly get up and still feel dizzy from the drug but he can clearly see someone and soon his vision clears up and he sees Fiona as she smirked at him and said.

Fiona: (smirk) Your finally awake. How was your nap?

Y/n glare at her as he walked over to her and tell her.

Y/n: How can you do this? I trusted you?!

Fiona: (smirk) Well now you know how it feels to be betrayed by others who is closest to you.

Y/n: Just why are you doing this for? What goal do you wish to have?

Fiona: I want to make Sally and the others pay for abandoning me all these years and I've teamed up with someone to succeed my revenge.

Y/n: Do you really think revenge is the only way to be happy? Your just gonna throw away your friends and the bounds you have for them just so you can get you revenge because you believe they abandon you? You didn't even know how they feel when they thought you were dead.

Fiona: I'll make sure my revenge will be complete and your gonna help us.

Y/n: What are you gonna do to me?

Sudden the door open and a familiar two tailed fox approaches them as Y/n is shocked to see it was Tails.

Y/n: (shocked) Tails?!

Anti-Tails: Oh, he's awake. I was hoping he would have died from the drugs effects.

Fiona: You want Scourge to beat you if Y/n is dead?

Anti-Tails: (little scared) N-N-No.

Fiona: Well it's a good thing he's alive.

Y/n: You still haven't tell me what you are going to do with me?

Fiona: (smirk) Well your electricity power would be very useful to break through different universes so we can take over all different dimensions. In fact, your counter part was use but.....let's just say he didn't last long. We onky have enough to travel to your universe and getting you before he was......turned to ashes.

Y/n is horrified by this while Anti-Tails and Fiona make theie leave and once they were gone Y/n looked around at his cell and then try to use hid chaos power but noting happened. He then noticed a device on his wrist which must be blocking his chaos powers.

Y/n: (thought) Great. What should I do? Without my chaos powers, I'm trapped. Let's just hope Sonic and the others will find their way here and save me. Hopefully they are okay.

He turn away and try to think of a way to get out when he sees a cell lock and sees that it is rusting. He looked around the cell and with the ghost is clear he slammed us shoulder onto the cell door a few times. After a few slams he step back and then he slammed his shoulder onto the cell door and the lock broke and he was free.

He rush out the cell and look around and then start to make a run for it. He leave the cell and enter the hallway as he make his escape to the exit. He looked around for the exit and soon he sees one up ahead as he races towards it when suddenly Omage appear in front of him but he was blue with a peace symbol on his shoulder as he immediately slapped Y/n back and he land hard onto the floor.

???: Your not going anywhere.

Y/n: Wait? That's not Omega voice, I sounded like....Bunnie?

Anti-Bunnie: That's right. Let's just say this junk bot is mine to control. Now, time to go back to your cell.

He turns to run another way but then Anti-Antine appear and pulled out his sword at Y/n as he tells him.

Amti-Antine: (smirk) Sorry but I afraid this is the end of you.

He was now surrounded as he try to think of a way to escape when suddenly a portal appear below him and he fell through while Anti-Bonnie and Anti-Antine rush over but the portal closes before they could make it.

Meanwhile Y/n fell and landed softly onto some pillows. He was surprised that just happened as he stood up and look around to find himself in a workshop.

Y/n: (thought) Wait, this place looks familiar.

???: Thank goodness your safe.

He turn to see Anti-Starline enter the room as he rush over to Y/n and immediately shake his hand.

Anti-Starline: I am truly am sorry! I wasn't sure the fall might hurt you so I place down some pillows so you can land safely but I hope you are okay and safe.

Y/n: (surprised) U-Um I'm okay......I guess.

Anti-Starline: (smile) I am happy that you are okay. Please, follow me, Dr Kintobor wants to see if you are okay.

Y/n: (thought) Dr Kintobor?

He follows Anti-Staline through the base and Y/n is surprised to see friendly robots as they walk by and saying hello or hi to Y/n. He find this very weird and soon enters a large room where they see a very thin man looking through the monitors as Anti-Starline calls out to him.

Anti-Starline: Dr Kintobor, I've brought Y/n and he's alright and safe.

He then turn to them and he has a friendly smile on his face as he tells Anti-Starline.

Dr Kintobor: (smile) Good job. Please leave, I would like to speak to Y/n alone.

Anti-Starline: (smile) Sure thing Dr Kintobor.

He turn and make his leave and once that Dr Kintobor walked up to him and reach out his hand to Y/n as he introduce himself to him.

Dr Kintobor: (smile) A pleasure to meet you. My name is Dr Ivo Kintobor but others call me Dr Kintobor, how nice to meet you.

Y/n: Um same. Sorry but I'm just still confused on what is going on here.

Dr Kintobor: Oh I completely understand your confusion. Please, let's sit down at my break room and I will tell you everything, I've even made some good cookies if you wish to try some.

Y/n: Um....sure?

Y/n: (thought) Okay this has to be a dream or something because this is just too confusing right now!
