Here we go with 15 thecoolj here just want to say thanks to all of you for supporting me and we had some fun now enjoy the story.
Our story begins with Princess Celestia at her throne and right at that moment guards came in with news for the Princess.
Royal Guard: Princess we have great news.
Princess Celestia: Oh what might that be?
Royal Guard: The gems Sonic called "Chaos Emeralds" we have them all.
Princess Celestia: Oh that is great but terrible news.
Royal Guard: Why is that Princess?
Princess Celestia: It's good that Sonic will be able to return to his home world, but he has made friendships with Twilight and each of her friends and now with him leaving that will leave everypony and Sonic depressed.
The Princess was sad herself but she had to do what was right even though it wasn't the best choice. She wrote the letter and using her magic it was transported to Twilight.
Meanwhile at Golden Oaks Library no pony was there only Spike who was cleaning up. Just like magic the letter landed on Spike's head.
Spike: Huh? Oh a letter from Princess Celestia let's see what it says *reading the letter* no how am I gonna tell this to Twilight and the others.
Spike went to go find the ponies to tell them the news, but what he didn't know that they were all stargazing with Sonic.
Twilight: Wow just look at those stars.
Applejack: Yeah just make a pony wish there was a way to tell how many are really up there?
Pinkie Pie: I bet there is about a billion trillion zillion stars.
Rarity: That would be amazing Pinkie Pie I mean look at them they shine like diamonds.
Fluttershy: So many diamonds, Rarity you would be making dresses forever.
Rainbow Dash: Haha good one Fluttershy. So Sonic what do you think of the stars?
Sonic: Heh heh I already reached for the stars.
Everypony: Really!
Sonic: Yeah big adventure had to save aliens from a dangerous amusement park from Eggman.
Rainbow Dash: Whoa.
Twilight: Just curious what did you learn from that?
Sonic: I learned the biggest lesson of all time I can't outrun a black hole.
Pinkie Pie: So you does that mean your really not that fast.
Sonic: What no I wasn't using my Sonic Boost at the time cause if I was doing that I could of easily beaten that black hole.
Rainbow Dash: Sure you could.
Sonic: Oh you want to go I can run backwards with my eyes closed and still beat you.
Sonic and the ponies began laughing but along comes Spike who sweating and looking nervous.
Twilight: Spike what's wrong.
Spike: Umm I need to speak you all alone. Sonic I'm sorry can you give us 5 minutes.
Sonic: Sure Spike but only 5 minutes.
The True Blue Hedgehog just ran away giving Spike the 5 minutes he needed to talk to the ponies.
Twilight: What's on your mind Spike.
Spike: *Sigh* Read this letter.
Twilight: Ahem my faithful student Twilight Sparkle I have news that is both good and bad we have successfully retrieved all of Sonic's chaos emeralds this means that Sonic can go back home but that also means he will be leaving us I am truly sorry your Mentor Princess Celestia.
Everpony: What!?
Rainbow Dash: That is so not cool!
Pinkie Pie: Not cool at all!
Applejack: Don't that beat all we were just getting to know him!
Rarity: This just awful our little Sony Wony!
Fluttershy: Sonic is leaving us? *Crying*
Twilight: Girls we have to stay strong remember our friendship with him is strong so he'll still remember us. Right?
Sonic: Of course I will your my best friends.
To the ponies surprise Sonic was just standing right behind them.
Sonic: Your all crazy if you think I will ever forget about you guys. I mean I learned a lot from all you ponies. I learned how there are others that rival my speed.
Rainbow Dash: Heh heh thank you.
Sonic: And how to make a Pinkie Promise.
Pinkie Promise: Yay you learned that from me.
Sonic: And how to make others braver than they already are.
Fluttershy: Thank you.
Sonic: And I was able (or should I say force) to model a fantastic outfit.
Rarity: *Giggles* Still a charmer.
Sonic: And if I ever want a job somepony helped me practice advertising.
Applejack: Haha no one can wear a apple better than you.
Twilight: Don't forget you helped three young ponies find there cutie marks.
Sonic: Hey I won't forget and Twilight don't forget to have a lot of adventures when I'm gone.
All the ponies and Spike gave Sonic a group hug because they all knew they will all be friends forever. The next day in Ponyville the Princess came and presented Sonic with the 7 chaos emeralds.
Spike: Wow those look delicious.
Twilight: Don't even think about it.
Sonic focused all the emeralds which made them circled around him and in flash they disappeared into him and he became the gold all mighty Super Sonic.
Everypony: Whoa!
Spike: Totally awesome.
Super Sonic: Heh if you think that was cool check this out.
The Super hedgehog began to fly in the air and then boom he was leaving.
Rainbow Dash: Nooo.
Fluttershy: What's wrong Rainbow Dash?
Rainbow Dash: I can't let him leave like this.
The speedy Pegasus flew at her top speed trying to keep up with Super Sonic who was barely even trying.
Super Sonic: Huh R.D. what is it?
Rainbow Dash: Promise you'll come back! *Tears in her eye*
Super Sonic: Rainbow Dash I Pinkie Promise.
Rainbow Dash was happy with that remark and gave Super Sonic a quick kiss on the cheek.
Rainbow Dash: You better or i will be really mad.
With all said and done Super Sonic used his powers to go into space and time again.
Twilight: Well he's gone.
Rainbow Dash: Don't worry he'll be back.
Applejack: That's great but Rainbow what did you do up there.
Rainbow Dash: *Blushing* Nothing.
Pinkie Pie: Oh my YOU KISSED SONIC DIDN'T YOU.
Rainbow Dash: What no I didn't!
Rarity: Well that makes his second kiss from a pony.
Rainbow Dash: Oh be quiet!
Fluttershy: Maybe when he comes back maybe I can-
Rainbow Dash: What was that Fluttershy?
Fluttershy: Oh nothing. *Blushing*
