Everyone cheer were about to hit number 20 thecoolj is here so get ready for awesomeness. Sonic is owned by Sega and MLPFIM is owned by Hasbro enjoy. Oh yeah there will be some references to a new story crossover.
Outside of Ponyville was Sonic the Hedgehog tapping his foot and rapid speed waiting for the ponies.
Sonic: Come on girls.
Rainbow Dash: Keep your shoes on hedgehog!
Sonic: I'm waaaiitting!
The ponies had bags strapped around them and Spike carried the Elements of Harmony putting in their bags.
Sonic: Are we all set?
Everypony & Spike: Yup.
Sonic: Good.
The blue hedgehog then turned into his Super form.
Super Sonic: Okay then lets do it to it.
Super Sonic open the portal between Equestria and Mobius. The ponies and dragon stood in awe at what Sonic had done but quickly went through. Flying through time and space the ponies and dragon again were in awe at what they saw.
Twilight: Incredible.
Rarity: Absolutely marvelous.
Applejack: Your darn right.
Pinkie Pie: Sonic what would happen if were to stop?
Super Sonic: Well you would be in a different world.
Fluttershy: Um what kind of world?
Super Sonic: Not certain but probably a world where you meet a Italian man fighting to save a princess.
Spike: Seriously.
Rainbow Dash: Yeah, you gotta be making that up.
Super Sonic: No I'm telling the truth, but that's a different story. Okay it looks like were here.
Super Sonic, the Mane Six and Spike have arrived to Sonic's world! They saw all the horror that Sonic had described.
Fluttershy: This is just awful.
Super Sonic: Yeah I know and gets me angry that I wasn't here to stop it.
Twilight: Sonic it's not your fault.
Super Sonic began to power down to his normal form and he had made a hole to bury the Chaos Emeralds.
Spike: Why are you doing that?
Sonic: Because if Eggman is able to get at least one then we are in deep trouble. Besides remember how powerful Metal Sonic was when he got one.
Rainbow Dash: Okay then what are we supposed to do?
Sonic: Make a plan.
Just at that moment robots surrounded the gang.
Applejack: Oh this can't be good.
The robots were about to open fire but something fast stop them with a homing attack. They were destroyed creating a explosion in smoke.
Pinkie Pie: Whoa that was incredible Sonic.
Sonic: Pinkie Pie that wasn't me.
?: Where have you been faker?
Rarity: Who said that?
Sonic: Oh great him.
Arising from the smoke was a black hedgehog. He was holding a destroyed robot's head and with a sinister smile he threw it in the air and yelled Chaos Spear. A blast of energy came from his hand and destroyed the head.
Spike: Okay that was a bit overkill.
Fluttershy: Who is that?
Sonic: That my friends is Shadow the Hedgehog.
Rainbow Dash: Shadow?
Pinkie Pie: Oh I get it he's your brother right.
Sonic & Shadow: No.
Shadow: I am the Ultimate Lifeform created by Dr. Gerald Robotnik. Wait a minute what am I doing? What in the world are you creatures?
Rainbow Dash: Creatures, listen pal-
Applejack: Whoa, whoa, easy there RD.
Twilight: Ahem we are ponies Shadow.
Spike: And I'm a dragon.
Shadow: *Puts his hand to his head* Blue hedgehog please don't tell me you have been playing with ponies and a pint size dragon the entire time Eggman has began the attack.
Sonic: Well umm this was kinda Eggman's fault, but technically yeah.
Shadow: That's all I needed to here.
Shadow gave Sonic a hard punch to the face knocking the blue hedgehog down. This angered Sonic so he gave Shadow a kick to the gut. A fight began between the two and the ponies and Spike did not know what to do.
Spike: What should we do?
Rainbow Dash: Well duh we gotta help Sonic.
Twilight: Wait a minute girls, I have an idea.
Twilight and Rarity combined their magic and used it to hold back both hedgehogs.
Shadow: What the? Release me!
Rarity: With that attitude, I don't think so.
Twilight: Listen both of you if we are going save your worlds we are going to have to work together.
Sonic: *Sigh* Ok faker we have to team up.
Shadow: I don't think so just give me the Chaos Emeralds and I will end this now.
Sonic: Sorry but that's not an option.
Sonic used his power of the emeralds to lift them from the dirt and scatter them around Mobius.
Shadow: YOU FOOL! Now how are we going to defeat the Doctor.
Sonic: With the superpower of teamwork.
Shadow: Ugh, you said that again.
Sonic: Heh heh sorry. Okay hedgehog, dragon, and ponies it's time for a team up.
Sonic has made his return home again but this time he brought his new friends and now with the help of Shadow will they be able to defeat Eggman.
