Sonic and Buddy were farewell each other and Sonic running on his own way and Buddy also running his own way by his grappling hook . Meanwhile after defeated , Sonic and his friend thinks Eggman has died inside his Death Egg Robot . But it wasn't true and it's just a controversy question about Dr. Eggman .

Unknown another dimension

After the event of Sonic Forces , Eggman has opened his eyes and he saw he was lying on the grass

Eggman : Ah ! Where am i ?! Did i was...actually dead ?! No , it wasn't . I'm still alive...but...how ?

Then he's get up to stand and he's seen everything around just the forest unlike Green Hill zone or else . His Death Egg Robot has also appeared behind Dr. Eggman while his robot has burning with flames

Eggman : Where am i ?! I think that's must be Phamton Ruby's enegry was send me here after i was being defeated by Sonic and his rodents ?! Could it be ?

? : AH boss

Eggman : What it is ?

Orbot and Cubot also here too with Eggman where they both decided to voluntary for Eggman .

Orbot : Boss . I think we were came at another dimension after Sonic and his friend were defeating us

Eggman : So this is how Sonic and his friends takes me to this another dimension ?! Maybe i seen Sonic was take me to another dimension is...actually exactly we're here . Beside , i'm not actually to meet that blue ball anymore causing they thinks me i was dead inside that Death Egg Robot . And that means is : We will never met Sonic and his friend again until they never see me anymore . That's why we came here and we shall conquer this world just we took Sonic's world only 99% but now . I will take this world only 100% and i'll modernization my army to become the strongest army in this universe *laugh*

Cubot : That doesn't make sense ?

Orbot : You were right , dude

Eggman : Anyway , so Orbot and Cubot !

Orbot : Yes , boss ?

Eggman : I want every part of Death Egg Robot to build the portal gate and we shall collecting all my weapon accessories where we've left them . By the way , before we start . Why would we've just able to need for Infinite to help causing Phamton Ruby's power inside at him . But i think Infinite was dead already by Phamton Ruby's power anyway ?

? : Is that what'd you were saying , doctor ?

Eggman : Hmm ! That's voice ?!

(Infinite's theme - Sonic Forces soundtrack)

Eggman has surpised where he seens Infinite has still alive after Sonic and Buddy defeating him and be fading by the affect of Phamton Ruby's power . But now , Infinite has no more to be fading and he's getting more stronger than

Eggman : Infinite ? How ?! You supposed to be dead by the affect of Phamton Ruby's power and how could you do that ?

Infinite : *laugh* As you can see , doctor . When i was defeated , i'm fleeing away when i was fading by Phantom Ruby's power to your base . Then i deploying all the machines to restoring my Phamton Ruby on my chest before you almost being defeated and lose this war . Once i restores my Phamton Ruby , i'm flying through the Null Space to save you to another dimension after that Blue jelly and his bugs defeating you . That's why i was able to take you to another dimension to avoid that blue jelly where we were face-off

Eggman : That does make sense , Infinite . I suggest you done well . But however , we've must processing our project to built the portal to take all our weapon accessories to remobilization our troop and ready to conquer this world unlike Sonic's world

Infinite : I'm afraid is somebody tried to conquer this world

Eggman : Who ? who dare to conquer this world ?

Infinite : Maybe the another empire from the southwest coast

Eggman : I see . But i won't let them take this world until my power will take down easily with this technology . Infinite , help me to finish our business we've did

Infinite : Understood . Doctor . And by the way . This is where we're start onto this world and this world wasn't belong for something or someone . Neither human or mobian... This is the world was belong to : Pony

Eggman : Pony ? Are you talking about the children's story ?

Infinite : Of course not , doc . This world is belong to the pony and these ponies aren't may not to stopped us whatever it take . Pony may control their magic (unicorn) , power (earth) and the pony on the sky with these wings (pegasus) where they lived in the peace as we prepared to start the war

Eggman : Hey Infinite . I think you might be lost your mind don't you ? I see you talking about these nonsense like the crazy or are you were being mental disorder by that your Phamton Ruby on your chest ?!

Infinite : *laugh* If you don't understand . Orbot , Cubot . Is that right what'd i said ?

Orbot : Well . According to Infinite , this world wasn't belong to human or mobian . But it might be belong to pony and he's said : Pony may control their magic (unicorn) , power (earth) and the pony on the sky with these wings (pegasus) where they lived in the peace as we prepared to start the war . He's right , we were came at this world since Sonic and his friends destroyed Death Egg Robot in this time .

Cubot : But , Orbot . Would you tell us about the name of this world ?

Orbot : Well . The name of this world . There it is ! I found it . It's Equestria , the name of this world

Eggman : Equestria ?! I didn't heard about this name

Orbot : Well . Equestria is inhabited by magical ponies and other talking creatures, such as griffons and dragons. Other animals and creatures also live in Equestria. Equestria is called a kingdom of horse . Equestria is co-ruled by Princess Celestia and Princess Luna, who reside in a palace in the city of Canterlot . Princess Cadence , who reside in a tower palace in the city of Crystal Empire and Princess Twilight Sparkle , who reside in a tower palace in the city of Ponyville . Equestria has many locations and their exact affiliation with Equestria is not explored.

Eggman : Hmm... I see . But i have a question to you , Orbot . Does Equestria have a oil to drilling the oil

Orbot : Of course , boss . Equestria has many the oils from several location . Including the desert from the south (Appleloosa) . But however , not just the oil where'd you think . Even bauxite , gold and other were also here too since we've didn't explore enough

Eggman : Hmmm..Seeing we're finally knew this world . Anyway , Orbot , Cubot . I don't want to waste my time and go back to built the portal (This is how i was beginning to conquer the new world since i was being defeated by Sonic and his friends . But now , in this time . I'll never able to met Sonic again and other rodent who tried to fight me at this world . I can fixed my empire to become the great empire where i'd start . Once i captured Equestria , those ponies will be able to accepted my new order if who dare to resisted me just like those rodent's did ! 99% and i'll make this empire just only 100% to conquer this world !)

But now the city is under reconstruction after war against Eggman Empire like : Remove all Badnik scraps where Eggman left away , transport those bricks , the long woods , the bag of cements and other where they'd need all these items very necessary to reconstruction the city . But suddenly , 3 C130 cargo planes were flying on the sky to dropping those parachute supply boxes for aid . But however , these planes were actually come from another dimension like the Earth where the human live and 3 C130 cargo planes was used by G.U.N where Shadow , Rouge sent 3 C130 cargo planes for humanitation aid mission . Then Buddy has show-off when he's running faster to go back the resistance base . He's avoid the long wood where 2 mobians bring to somewhere and other...Once Buddy avoids these construction .

Buddy : Nope ! But I'm not come here for help , beside i've just come here for something need to do

Knuckles : What it is ?

(World Map (Episode Shadow) - Sonic Forces soundtrack)

After they done the job to bring these items to carton boxes , Buddy sends memory card of camera to the computer and Amy begun to research on the computer . Then all the picture where Buddy was captured has on the big screen . Knuckles and other has very surprised where they saw Eggman's robot was retreated to another dimension

Vector : So this is where those Eggman's robot want able to retreated to another dimension , right ?

Tails : In fact . They might be they went back where they came from since Eggman has died inside his Death Egg Robot

Espio : I don't understand why they would able to retreat ?

Charmy : It's doesn't matter why would they retreat . It would be the withdraw ?

Silver : I think it might not the withdraw . But maybe is something wrong inside that portal . But you've just look at the portal gate and you'll see this gate is a purple indigo color . Neither Phamton Ruby or Chaos Emeralds

Knuckles : Without the Phamton Ruby or not . But why could they do that ?

? : Because , they doesn't want to retreat ?

Silver : Shadow . You're here too ?

Shadow : Of course i'am . Anyway so guys , this retreat is not be happened without the withdraw and they marching to this portal gate for new invasion of another world . Plus , i think Eggman is not dead already and even Infinite

All : What ?!

Espio : How's you knew that ?

Shadow : After Sonic and Buddy beats him down . He's fleeing away to the base and he's restore the Phamton Ruby's power source until Eggman unleashed his Death Egg Robot to fight Sonic and Buddy . After Eggman defeated , Infinite saves him from Sonic and Buddy , and they moves to another dimension . Now Eggman is begun to processing the new invasion of another dimension alongside Infinite . Then also , he will not able to meet us again until the post-war is ended

Tails : How did you know about that , Shadow ?

Vector : Did he's said : Infinite's still alive ?

Shadow : Since i knew his plot what'd he did . But however , with the Phamton Ruby destroyed . Eggman is creating the another copied Phamton Ruby instead the Orignal Phamton Ruby where Buddy saves us from the sun .

Silver : Wait . Did you just say : Eggman is creating another copied Phamton Ruby ?! That doesn't make sense . If Eggman creating this fake thing , it would be make the disaster for him by Fake Phamton Ruby . Plus Phamton Ruby is only gem in this world since we didn't able to explore out somewhere

Shadow : But i think i wasn't fake Phamton Ruby to effect the portal gate . But i think Infinite might be effecting the portal gate by his Phamton Ruby's power

Knuckles : So that's why he need those robots to rebuild his fortress to invade another dimension

Silver : Could be Sol Dimension or Human World (Earth) ?

Amy ; But it's not . They didn't want invade Human World or even Sol Dimension . But according to Eggman's robot , these Eggman's robot was moving foward to another dimension . The next dimension where Eggman and Infinite here is : Equestria

Espio : Equestria , the land of pony ?

Vector : Wait . Did you've said : Equestria ?

Charmy : This is how i'm become the pony's fan

Amy : Equestria is inhabited by magical ponies and other talking creatures, such as griffons and dragons. Other animals and creatures also live in Equestria. Equestria is called a kingdom of horse . Equestria is co-ruled by Princess Celestia and Princess Luna, who reside in a palace in the city of Canterlot . Princess Cadence , who reside in a tower palace in the city of Crystal Empire and Princess Twilight Sparkle , who reside in a tower palace in the city of Ponyville . Equestria has many locations and their exact affiliation with Equestria is not explored . That's must be how Eggman want to invade this land

Espio : After the war ended . So why would Equestria wanted us save them after we've just overthrow Eggman Empire in our world . I suggest i'm protest Eggman invades another world since Sonic wasn't adventure this world

Vector : In fact . If we're saved Equestria from the wrong hand of Eggman Empire . But we need Sonic and the 7 Chaos Emerald to make our portal to get in there

(Resistance's theme- Sonic Forces soundtrack)

Knuckles : Vector's right . We had to save Equestria just we fought against Eggman Empire . But now , our chance is ready to do and we ready to become the volunteer of Equestria . So guys , who joined us ?

Vector : I'm ready !

Then , Spike has arrived the castle and he's bring all those scrolls to Twilight

Spike : Okay, Twilight. Got all your charts and graphs.

Twilight : Oh, thank goodness you're here, Spike! I'm just so nervous about this meeting!

Spike : What are you talking about ?

Twilight : *sigh* I'm about to ask the three most royal princesses of Equestria for a huge favor! What if they reject me?

Spike : It'll be fine. Just remember the most important thing.

Twilight : Smile ?!

Spike : Eh... no. You're a Princess, too

Twilight : Right !

Then Twilight opened the door by her magic and they both move to throne room where Princess Celestia , Cadence and Luna are waiting for Twilight

Cadence : Ponies have been arriving from all over all morning.

Luna : I'd like to think it's to see us, but Songbird Serenade might be the bigger attraction.

Twilight : Yes, she is the... "mane" event! And to make it extra special, I could use your help. Spike?

Spike pushing the board behind Twilight and Twilight is ready to take black marker write and draw by her magic

Twilight : Songbird Serenade's performance is not scheduled to start until after you begin the sunset. And based on my precise calculation, to get the very best lighting for the stage, Princess Celestia, I was hoping you could make sure the sun stays about 28.1º to the south, and, Princess Luna, if you could raise the moon 62º to the north at the same time, it would reflect the sunlight on the other side and really frame the entire stage perfectly!

Luna : I...

Twilight : But wait! There's more! Cadance, if you could use your crystal magic to create an aurora above the stage, the sun and the moon will shine through it and create a truly amazing light show!

Spike : Presenting Songbird Serenade!

Spike get up the top of board where he's wielding Songbird Serenade (Sia)'s wood . But unfortunately for Spike , he falls down the ground

Spike : Ta-da !

Twilight spread her wings and 3 Princesses didn't understand what'd Twilight said

Luna : So you're saying you want us to move the sun and the moon for the party.

Twilight : Well, I'd do it myself, except I don't have your magic *snort*

Celestia : Twilight, each of us uses our powers to serve Equestria in our own way. You are the Princess of Friendship. You already have all the magic you need.

Twilight : So... that'd be a no?

Rarity : If you were raised in a barn! Ahem, no offense, Applejack.

Applejack pouring apple cider on the cup and she puts on the table while she's talking with Rarity . Then Rainbow drinks the cider and Applejack pours again and Rainbow drinks again...

Applejack : None taken. Especially since I wasn't raised in a barn. My family just happens to have a barn. Where I was born. And... spent most of my formative years...

Rainbow : You were raised in a barn!

Then Twilight and Spike has show-off when she's checking those scrolls

Rarity : Hello , Spike

Spike : Uh, hi, Rarity. Heh heh.

Applejack : How'd it go with the other Princesses? They like your idea?

Pinkie : I bet they loved it!

Twilight : *sigh* Not exactly. They think I can make today perfect without their magic.

Rarity : And they are absolutely right, darling. This festival is your brilliant idea and we know you're up to the task!

Twilight : But what if I'm not?! What if Songbird Serenade hates the stage?! Or nopony makes a new friend?! And if I failed the festival, then who am I?!

Pinkie : Twilight, look at me! This will be the biggest celebration Equestria has ever seen! As the Princess of Friendship, you cannot fail! This day will define who you are! The pressure is intense! It's almost too much for any single pony to handle! *scream*
