Part 2 Prologue

Finale


"*Laughing His Tail Off After Listening To What Happen Of Sonic* BWHAHAHAHAHA! Out of all people to become this so-called Master. It had to be you, Sonic!" Knuckles laughing

"I mean, it wasn't my intention to be a Master in the first place when I arrived on that planet, but here I am, a Master to these Servants for the past several months or years now in Mash's world, but I'm happy to be best friends with many legendary Heroes and villains! Especially my best friend, Mash Kyrielight! Isn't that right, pal?" Sonic replied

"I'm happy I got to meet you and become my Master, Senpai! Our friendship will never be broken! *High-Fives Sonic* No matter where you go, I'll always be on your side!" Mash said

"Sure, you two can be friends as much as you want, but it's the thought that Sonic had to travel multiple years and meet Historical figures from the real world at Mash's world and not know a single bit about them. Nevertheless, I'm glad you came fine at the end and showed that Goetia guy not to mess with any Mobian again." Knuckles said

"And the only time he will mess with destroying the world he was quite annoying listing to, so I decided to give him a chill pill to calm him down," Sonic replied

"*Finishes Healing Knuckles With The First Aid That Tails Had Inside The Tornado* Alright, I think that's every placed bandage. How do you feel, Knuckles?" Mash asks

"*Slowly Getting Up And Moving His Arms Around* Hey, I feel better already. I'm ready to continue fighting Eggman's robot once again! Thanks for the assist, Mash. For someone like you, you top noticed it!" Knuckles replied

"Just doing my best to help out Master's friends as much as I can, even if myself is from another world," Mash said

"Well then, since Knuckles is feeling better than when we arrived, we should get going and meet Eggman and this Koyanskaya person to get Master Emerald back. Are you coming with us, Knux?" Sonic said

"I would give Eggman a piece of my mind, but I have seen many robots occupying Angel Island, and I need to remove them from destroying this place. The Island may have fallen, but the inhabitants need a home to live in, and I can't let these guys ruin it for them. So you three go on and take care of Eggman for me." Knuckles said

"Are you sure you'll be okay, Knuckles?" Tails ask

"Don't get sad when I'm around, Tails. We've known each other for a while. You know I always continue the fight even with a couple of scratches around my body won't completely stop me. You three go without me." Knuckles replied

"You heard the guy, Tails. Besides, we have other powerful Servants back in your lab that will come and help us settle with those two. Now come on, let's take Master Emerald back and return it to Angel Island before they do anything with it." Sonic said

"Alright, Sonic! If the others are coming with us, I need to use the X-Tornado and take us all towards Eggman's lab. Come on, Sonic and Mash, let's go!" Tails replied

"Oh, so you recreated that aircraft

"Wait, I have to ask, Tails. Did you make those planes all by yourself?" Mash asks

"The plane we used is Sonic's, but he lets me use it much more than he does. And The X-Tornado was a replacement for it, but I decided to build it separately, so now we have two planes we can use." Tails replied

"Da Vinci would be proud to see someone genius like Tails creating vehicles for all sorts of occasions!" Sonic said

"Indeed, Senpai. Those two would instantly be great friends regarding building devices." Mash replied


*Later*

"*Piloting The X-Tornado* We should be heading to Eggman's Lab in just two minutes! How are you guys holding up behind there?" Tails ask

"Just like last, a little worried about how fast we are going. I'm anxious about Sonic, just outside the vehicle, standing on top of it like nothing. Senpai!" Mash said

"As I said before, Mash, I'm used to this stuff! As long as you seven are fine, that's all it matters here! Good thing Edison is making some good progress with the teleporter as we speak."

"*Raises Her Arms Up High* YAAAAAAAAAY! This is very fun, Master! This is one of the best honeymoons you can give to me!" Tamamo Cat Excited

"Try not to be excited for too long, Cat. We are just about to arrive at this location, and no doubt, enemies will be attacking us, so we have to be prepared." Sita said

"Little Blue! The number of venues around the city is staggering! I can do even more concerts around here than I'm capable of back in my Castle! If possible, we can invite every Servant over here where I can make a private concert for only us to enjoy in this beautiful city!" Elizabeth said

"That is, of course, we take care of Eggman and Koyanskaya first, then we can do something like that later," Sonic replied

"Master, no time for daydreaming! I see enemies heading towards us!" Atalanta said

"Atalanta's right, Senpai. Enemies are heading towards us!" Mash warned

"Sonic, several Spinners are heading towards us! Mind taking them out for us quickly?" Tails ask

"Don't need to tell me twice. I'm on it!" Sonic replied

Sonic notices the Spinners heading towards the X-Tornado as he quickly gets a running start, curls into a ball, and homing attacks all the Spinners, destroying them in a matter of seconds. Sonic notices more Spinners heading toward the X-Tornado as he is about to homing attack them again until he notices Arrows flying past him, hitting the Spinners and exploding soon after. Sonic looks back and sees Atalanta and Sita jumping out of the X-Tornado alongside Mash, Elizabeth, and Tamamo Cat as the six fall straight down towards Eggman's Lab.

"You guys!" Sonic said

"You all go ahead! I'll be here outside taking care of the other Badnicks while you all go deal with those two! Stop them from whatever they are about to do and retrieve Master Emerald! *Flies Away, Leaving Sonic The Servants Behind*."

"You heard him, Senpai! We need to retrieve that Master Emerald before it's too late!" Mash shouted

"You're right! Let's get going now! *Falls Even After Down As The Rest Follow Behind And Towards Eggman's Lab* Here we come. Egghead!" Sonic shouted


*Eggman's Lab, Control Room*

"*Watching The Badniks Safely Place Master Emerald Inside Its Socket* Yes, perfect! Everything is going smoothly right now.

"WARNING! WARNING! INTRUDER ALERT! INTRUDE ALERT! THE LAB IS CURRENTLY UNDER ATTACK! I REPEAT, THE LAB IS CURRENTLY BEING UNDER ATTACK!" The Announcement Said

"What?! What do you mean someone is infiltrating my lab? Who can that be? *See The Cameras On His Screen And Notice Sonic, Atalanta, Elizabeth, Tamamo Cat, And Sita Running Through The Hallways And Destroying The Badnicks As Well* Sonic?! Of course, it's him! But who the heck are those four with him?! Grrrrr... No matter if that means those others are working with Sonic, they must also be taken down! Badnicks, ATAAAAAAAACK!" Eggman shouted

"Where the heck is Mrs. Koyan? She's supposed to be helping me deal with the Rat and his new buddies!" Eggman thought


*Someplace Else Around Eggman's Lab*

"*Running Through The Hallways While Homing Attacking The Bandnicks* This way! This is the way towards Eggman's dumb control room! We shall reach it very soon!" Sonic said

"*Pushing The Enemies Away From Sonic And The Others* Dammit! The robots are tougher than I thought! They just keep coming!" Mash said

"*Slashing The Badnicks With Her Claws* These are more annoying than the Demon Pillars we had to fight before!" Tamamo Cat said

"*Shooting Arrows At The Badnicks* But the bright side, they are weaker than those Demon Pillars and easier to destroy," Atalanta replied

"*Slashing The Badnicks With Her Spear* Stay away from me, you weirdos! If you wanna autograph from yours truly, I suggest we form a line and handle this peacefully without fighting over another!" Elizabeth shouted

"*Shooting Arrows At The Badnicks As Well* Listen to what Elizabeth is saying, everyone; all she wants is to give you all a chance to meet her and allow you to take photos with her," Sita said

"*Continuing To Run* Say, here's a remarkable fact about this place. This was the last place I was before being teleported to Chaldea for the first time. I don't know if the teleporter that sent me there is still here but let it be known to you guys that this was the place that started it all!" Sonic said

"Master, please be serious. We don't want you to go to another world again and disappear from your world again. You already had enough in our world." Mash replied

"Yea, yea, you're right, Mash. We don't want that to happen once again. I get it, anyway. I see the door to the Control Room. Let's stop Eggman and Konyan once and for all!" Sonic said


*Control Room*

"*Currently Typing Down On The Buttons On His Computer Terminal* With a single press of a button, the Master Emerald shall begin its work to build me a new Death Egg that I can use for world domination! It's game over for you, Hedgehog! I win! HOHOHOHOHOHOHO! Now then... *Presses A Button As The Master Emerald Begins To Emit Light* HOHOHOHOHOHOHO! I finally won! In your face, Hedgehog! " Dr. Eggman laughed

"That's a nice little monologue you had there, Egghead. However, I'm not alone this time!" A Voice replied

"WHAT?! *Turns Around And Notices The Door Of The Control Busting Open And Notices Sonic And His Servants Standing There And Looking At Him* SONIC?! Why do you always have to come when my plans are also complete?! And who are those people behind you?!" Dr. Eggman said

"I'm glad you ask, Egghead! These people behind me are my best friends from that world you sent me several months ago! Your initial plan was to teleport me to a different world where I couldn't be able to get back here. But thanks to meeting so many friends along the way and their amazing help. I was able to return here in time to take you down! You thought you got the best of me? But that little happy-go moment comes crashing down now that I have finally returned!" Sonic replied

"Grrrrr! My plan to stop you failed again, thanks to you, your stupid friends, back in that other world you were stuck on! However, do you believe your friends will be able to win against me? I think not. You see, I have a companion who will easily take care of you six for me instantly. She's the reason why I have Master Emerald, to begin with! But before meeting her, let me introduce you to Sonic, an old friend! *A Blue Robot Appears In Front Of Dr. Eggman As It Starred At The Group* Everyone, I give you Metal Sonic!" Dr. Eggman shouted

"M-Metal Sonic?! Senpai?! He made a robot based on you?! It's like Elizabeth and both mecha Eli-Chans back at Chaldea!" Mash shock

"There are differences with the names already, Mash. Mecha Eli-Chan and METAL Sonic." Elizabeth said

"Impossible!" Atalanta shock

"Stand on guard, everyone! Prepare for battle!" Sita said

"That ugly Metallic thing is more useless than Master here! Do you think that thing will be able to defeat the real one?" Tamamo Cat said

"HOHOHOHO! Of course, it will! Metal Sonic! Do what you did to that Hedgehog before! Show them you still have what it takes!" Dr. Eggman commanded

Metal Sonic takes a fighting stance as the jet-booster roars to life and dashes towards Sonic and the Servants. Sonic and the rest all jumped away as Metal Sonic followed Sonic around. Metal Sonic lungs towards Sonic and attempts to stab Sonic in the chest but misses him due to his incredible dodging speed.

"Do you think you have a chance against me? I have already fought deadlier creatures in the past several months than what Egghead has to offer. You are just nothing but a weak pilke of garbage!" Sonic said

Metal Sonic continues to chase down Sonic and attempt to slash him, thanks to his experience in Chaldea. This was easier before as Sonic performs a backward roundhouse kick and knocks Metal Sonic away from them. Metal Sonic recovers on the ground and notices Mash and Elizabeth heading toward him as he activates his jet booster and takes off into the air. However, Elizabeth flies toward Metal as both begin clanging claws and spears toward one another, trying to attack one another.

"*Blocking Metal's Attacks* HA! Not even a failure like can outrun even a Servant! You may be modern with High-Tech, but it won't stop you from defeating me! *Swings Her Lance Down at metal And Throws Him Straight Down Towards The Ground Hard* Mash!" Elizabeth shouted

"On it! *She Rushes Towards Metal And Bashes Him With Her Shield And Does A Cross Shield Blade Attack That Sens Metal Flying Towards The Wall And Hitting It*."

"He's still going!" Sonic said

Metal Sonic rockets himself towards Mash, thrusting his claws straight for her head until she blocks his attack with her shield and bashes him away again. Tamamo Cat and Sita lunge towards Metal Sonic as Cat grabs Metal by both legs and begins smashing him on the ground over and over while laughing. The number of slams on the floor by Cat causes Metal Sonic to malfunction slightly as she throws Metal straight into the air as Sita fires several arrows towards Metal Sonic, some of them puncturing him but mostly dodging it. Metal Sonic, damaged from the six, continues to fight as Sonic appears again as the two headbutted each other as one was running while the other was using its jet booster.

"Hahaha! Just like old times, Metal! I have to say. You are the reason why you are fighting against my friends and I right now! You're stupid robot body pushed me into the portal while we had our fight several months ago. However, I can't stop and thank you for making me meet wonderful friends who always have my back!" Sonic said

"*Getting Angry, His Jet Booster Goes Faster To Push Sonic Back, But Sonic Uses More Speed To Level The Field* ...!"

"He's distracted. Go, Cat!" Sonic shouted

"Right on it, Master! *Tackles Metal Sonic Away From Sonic As She begins Unleashing A Deveastaing Series Of Claw Slashes At Metal Sonic, Leaving Behind Scratch Marks Around His Metal Body And So On* This is for my Master, you pile of garbage!" Cat shouted

Moments later, Cat grabs Metal by the arm and throws him at Mash who takes a wide stance and makes a might swing of her shield and smashes Metal, causing his circuits to spark and crackle as he flies towards Eggman, knocking him and the two crashing into the wall.

"Get off me, you idiot! *Pushes Metal Off Of Him And Watching The Master Emerald Continue To Emit Light As The Others Continue Fighting Metal Sonic* Just a few more minutes and my plans will finally be at full force- *Is Suddenly Cut Off As A Gunshot Zooms Pass Him And Hits The Wall Of The Room* WHAT?! *Turns Around And Notices Koyanskaya Aiming Her Sniper Rifle At Him, Cocking Her Rifie And Firing At The Doter Himself* WHOA! *Ducks As The Bullet Zooms Over Him And Hits The Computer Terminal Behind Him* What the?! Mrs. Koyan?!" Dr. Eggman shock

Sonic, Mash, Atalanta, and the rest stopped fighting as they noticed Koyanskyaba firing her sniper rifle at Dr. Eggman and trying to kill him on the spot.

"Oops, sorry about Docter. Looks like my hands slipped a few times there. Hehe~" Koyanskyaba said

"Mrs. Koyanskyaba?! What are you doing?! Why are you aiming your weapon at me instead of our enemies?! I thought we agreed upon this?! I thought we were supposed to control the world together and create the Death Egg and Eggman's Amusement Park?!" Dr. Eggman shock

"The plan for world domination still stands, Docter. However, our goals differ from one another. You see, you want to control the world only for your satisfaction. Creating useless locations with no benefit whatsoever. However, for my goals, I want to create a world where animals don't get hurt by worthless humans and kill them for fun. That is why it hurts me seeing you hurt this poor little Blue creature in front of me. It makes wanna cry real tears." Koyanskyaba replied

"What?! Are you trying to say you are secretly on Sonic's side?! You told me before that you were going to get rid of that Hedgehog when we first met each other?!" Eggman said

"Don't think of this as some kind of betrayal. I'm just doing what's suitable for both of us. And that is to get rid of worthless of the face of this world. Starting with you! *Aims Her RIlfe At Eggman Once Again And Fires At Him* Do me a favor and stand still quickly. Don't make this hard for the two of us." Koyanskyaba said

Dr. Eggman begins to run around the Control Room as Koyanskyaba continues to shoot at him with her Sniper Rifle. Sonic and the others hid as they watched Eggman hide and duck around the room as bullets flew everywhere. Eventually, the mag of Koyan's sniper was empty as Koyan reloads her sniper, giving Eggman a chance to escape as he quickly rushes out of the Control Room, pushing Koyan out of the way and running into the hallways as fast as he can. Koyan didn't follow Eggman as she continued reloading her rifles until it was set and ready once again.

"No need to hide from me. I just want to talk with you. That's it." Koyanskyaba said

"*Stops Hiding With The Others And Shows Himself To Koyan* So, you're the one I heard about from a couple of my friends. The one who is working with Dr. Eggman?" Sonic asks

"It's a difficult thing to explain to you. A pleasure to meet you, cute animal. My name is Koyanskyaba. But you must be the one and only Sonic The Hedgehog. I heard much about you from the Docter and how much he despised you. However, there's more than meets the eye when it comes to you. Isn't that right, Master of Chaldea." Koyanskyaba replied

"*Eyes Widen* W-What?!" Mash surprise

"Don't be surprised about that news, Demi-Servant. We all know that Sonic is our world's last ever living Master. It's no wonder Chaldea implemented a Ban against the Mages Associations from them ever discovering about Sonic The Hedgehog. But at the same time, I'm glad you placed. I didn't know if I could ever forgive them if they found him and treat him like shit as anyone else who they think they one-up someone." Koyanskyaba said

"S-She knew everything either way. Us implementing the Ban against the Mages Association." Mash said

"From the looks of it, you just said, I'm guessing you don't work for them. However, how did you even get here in my world in the first place? And why do you eliminate this world's Humans just so animals can live in peace?" Sonic asks

"I was brought because of the Docter. He showed me this world of living beings and its inhabitants, and I thought it was quite an extraordinary place at first. However, I quickly realized that all of that was a lie after seeing the Docter kidnap many innocent creatures and use them as slaves for his robots just so that he can attack more creatures. That was enough for me to have a burden on this world's humans. Hence, I secretly hid my plans from the Docter so I could use that Master Emerald and use it for my benefit of getting rid of Humans off the face of this earth so that animals like you and your friends can live peacefully without humans." Koyanskyaba replied

"You just can't do something like Koyan. Look, I understand that your goal is to protect the animals from the harsh reality of humans mistreating them. But killing off humans in this place isn't the answer to all of this. Trust me when I say this, but Mobius is a world where Humans and creatures live together in peace. Our goals are always the same to take down Dr. Eggman from World domination. That's how it's been for the past many years now. We both know Eggman is the bigger threat here, and we strive to defeat him and ruin his plans by taking away our peace!" Sonic said

"Look, Sonic, all I'm trying to do is have a world where animals can live without them being hurt by humans anymore. You and I are animals who have seen our friends die off, and for what reason, of course? That is why I already had everything settled before I got here and worked with the Docter. *Walks Pass Sonic And The Others Towards The Master Emerald* Please understand, Sonic. I'm only doing it for the two of us. *Places The Palm Of Her hand On The Master Emerald And Closes Her Eyes*" Koyanskyaba replied

"Even if you wish to do so, Koyan. I won't let anyone change my home! Atalante and Sita!" Sonic shouts

"Got it, Master! *Both Aim At Koyanskyaba With Their Bows And Fired Arrows At Her As Sonic Begins Dashing Towards Her*." Atalanta And Sita both said

The two Arrows and Sonic were heading towards Koyanskyaba to stop what was happening. As Soni and the arrows got closer to Koyanskyaba, Metal Sonic suddenly comes rushing in, knocks Sonic, and breaks the arrows out of the way, still damaged from the attack and sparks coming out of its body as it kneels on the ground and smoke comes out it soon after. Sonic skids on the floor and looks at Koyanskyaba as the Master Emerald glows even brighter. Metal Sonic, not coded to know that Koyan was working with him, dashes towards her and attempts to stop her until, seconds later, a beam of light fills the room as everyone covers their eyes. The light engulfs everyone soon after.


It wasn't only that location that was engulfed by the light. Eventually, the entire planet was consumed by the Master Emeralds after Koyanskyaba placed her hands on it. New Islands suddenly appeared worldwide in several locations as the earth was covered in light. Islands that shouldn't exist in both Mash and Sonic's worlds. Floating Islands continued to form as people looked up from specific locations and noticed the floating Islands that suddenly appeared on Mobius. Eventually, everything dies down as these Floating Islands float above the clouds of particular areas with no background or name.


*A Few Days Later, Tails Workshop*

"Oh, man, this shouldn't have happened before..." Tails said

"*Looking At The Miles Electric With Tails* So that's what happened when the Master Emerald used its powers during our fight against Eggman?" Sonic said

"Yes, looking through the world map here in the Miles Electric. Several Islands were formed due to Master Emerald and are separated in multiple locations worldwide. These are Islands that never should've existed in our world, but here they are. If I have to guess, these Islands may have a connection with Mash's world. Something tells me about that." Tails replied

"From my world? Could that mean that the Master Emerald used its power to teleport several locations to Sonic's world, places my world shouldn't have seen?" Mash said

"That is correct; based on the reading I'm getting with the Islands, they come from somewhere outside your planet, Mash. This means these Islands were originally from your world's outer space or alternative dimension and to be used for something against your world. However, when the Master Emerald unleashed its power when it came in contact with this Koyan lady, you fought. The Emerald must have sensed something within her that has a connection with these Islands and thus brought them to our world. Thus, creating these unknown Islands from space." Tails explained

"More potent than the Chaos Emeralds, Mash. However, I still don't get it; if the Master Emerald formed Islands outside of Mash's world, then does it mean Servants and other living beings came from there as well?" Sonic asks

"That could be correct, Sonic. It wouldn't be Islands if Servants and beings from our world would be inhabiting it, right?" Edison said

"If you said that Servants may have also appeared in these Islands. Then who are their Masters? The only living Master left in our world is Sonic only." Atalanta said

"Based on what was said here just now. It could be that this Master Emerald is keeping these Servants alive without a Master and roaming around like they are actually under a Master as usual." Sita replied

"B-But that's impossible! Only the Master can keep a Servant alive! No way in Cat's life has seen anything else from a contract with Servants!" Tamamo Cat said

"What are we going to do with these Islands? We can't just let them stay here in Little Blue's world and expect us to not do anything about it." Elizabeth said

"That is correct, Elizabeth. Master saved our world from incineration. This is why his Servants will continue to help him deal with this situation. Luckily for all of us, Young Miles and I have finished setting up the teleporter back to Chaldea. We have the Chaos Emeralds ready for us to get back. I suggest we head back quickly and explain everything to both Da Vinci and the Director about this situation." Edison said

"Wait, you already completed the teleporter back to Chaldea? I thought it'll take longer than that, like back in Chaldea. It took months for you three to end the teleporter!" Sonic confuse

"Come on, Sonic, I built planes, robots, weapons, and other machinery for years already. Building a teleporter is like building a toaster! Quick and easy!" Tails replied

"Heh, always full of surprises, Tails. To this day, I'm glad we were able to meet that day when my Torando was broken down, and you fixed it. Who knows what would've happened

"Haha! I think about that time a lot as well! The plan is simple: Sonic and the rest will head back to Mash's world and explain what happened to everyone else. And once that happens, you'll return here with everything ready and will get going to these Islands and find a way to deal with these Islands from different dimensions. Easy, right?" Tails said

"Seems easy! Our next adventure will be here in my world this time! How fitting! Anyway, Edison, start the teleporter! Let's return to Chaldea as fast as possible!" Sonic said

"Of course, Master! To Chaldea, we return!" Edison roared

"Alright, everyone, get ready. This will be a bumpy ride again!" Sonic said

"I'll get myself ready in the meantime! I'll be waiting for your return, Sonic!" Tails said


*Chaldea*

Chaldea's Alarms went off as Da Vinci and Olga were confused about what was happening and why the alarms went off suddenly.

"*Currently In The Command Room With Da Vinci* What the hell is happening? Why is Chaldea's alarm system going off suddenly?" Olga asks

"Da Vinci! Director! We're back!" Mash said

"Mash?!" Olga shock

"Mash, Sonic, Edison, and everyone else! It's been a week and a half since you guys left! I'll love a nice reunion, but we are experiencing some malfunction in Chaldea. Don't worry. I will fix it right away." Da Vinci said

"The effects of that Master Emerald are happening already, Senpai!" Mash said

"Da Vinci! Olga! This isn't a malfunction! This is a serious threat to both our worlds!" Sonic said

"A threat to both our worlds? Sonic, what the hell is happening?! What's been going on in your world?!" Olga confuse

"The fight to save Humanity. Begins once again." Sonic replied


Mysterious Islands Have Appeared Around The Planet Mobius, Causing Disturbances In Both Sonic And Mash's World.

Together, Mobius And Chaldea Will Do Everything To Solve The Issue...

Even If They Are Worlds Apart...

The Islands From Alternative Dimensions Must be Destroyed...

The Gods Will Soon Realize Their Mistakes For Messing With Sonic's World...
