I'm back, one more time on this story then I'm officially done. Just felt like doing a OVA chapter for you guys. Sonic is owned by Sega and MLPFIM is owned by Hasbro, enjoy.
On a glorious sunny day in Mobius we find Sonic the Hedgehog on his normal runs around Green Hill Zone. He was feeling good today since he had saved two worlds and made awesome friends. Thinking of his friends so much he decided to make a quick visit and have a bit of fun with them.
Sonic: Alright time to go to Ponyville.
The blue hedgehog still had the Chaos Emeralds with him and quickly used their power to transform into Super Sonic. Super Sonic created the portal to Equestria and quickly went through it. The super hedgehog made it and decided to run in his normal form to Ponyville. Outside of Ponyville the Mane Six and Spike were having a picnic next to the lake.
Twilight: It is a beautiful day to have a pinic isn't everypony.
Applejack: It sure is and for this special occasion I have prepared a cake.
Spike: Whoa, *drooling* looks great.
Rainbow Dash: Well let's eat.
Before they could even cut a piece it a big chunk of it was gone. The ponies and little dragon were confused, they looked around and what they saw was a trail of cake crumbs leading up a tree.
Rarity: What do you suppose it is?
Fluttershy: Some kind of animal.
Rainbow Dash: But what animal moves that fast?
Twilight: Everypony don't you all remember that we had fun with a fast animal.
All of them soon realized who it was and began to laugh. Applejack went to the tree and gave it a good kick and falling out of it was Sonic the Hedgehog.
Sonic: What's up, Applejack good cake.
Everpony and Spike ran up to their spiky blue friend and gave him a hug. The group then went back to Ponyville and up in the sky Sonic saw a long trail of lightning clouds made by flying pegasi in the sky.
Sonic: Whoa who are those ponies.
Rainbow Dash: Your asking the right pony Sonic those are the Wonderbolts, a squad of Pegasus ponies who perform aerial acrobatics and demonstrations.
Sonic: That sounds cool.
Rainbow Dash: Not just cool awesome.
Spitfire, captain of the Wonderbolts, came flying down to the Mane Six.
Spitfire: Hey your Sonic the Hedgehog right.
Sonic: Uhhh yeah I'm Sonic the Hedgehog.
Spitfire: Mister Hedgehog I am Spitfire captain of the Wonderbolts and we were just wondering would you like to try out.
Everypony, Spike, and even Sonic was surprised to hear this. The blue hedgehog looked at his friends and they were shaking their heads yes.
Sonic: Sure, why not.
Spitfire: Yes, uh I mean very good decision. Be ready to show us your all at the Wonderbolts Academy.
The captain left with her squad leaving Sonic with such big news. Everypony and Spike was happy for Sonic but no pony was happier than Rainbow Dash.
Rainbow Dash: WHOOHOO! Sonic you are already cool but you might be a Wonderbolt and that won't just make you cool it will make you, uhhh Pinkie Pie make up a awesome word for Sonic.
Pinkie Pie: Let's see it's awesome plus cool so this will make Sonic "Coolsome" no wait, "Awecool" or "Awecoolsome".
Sonic: Wow three words to describe me, this is turning out to be a good day.
The gang who couldn't fly went on a hot air balloon, while Rainbow Dash and Fluttershy took to the sky.
Spike: Hey Sonic can't you fly.
Sonic: Yeah.
Spike: Then why are you in the balloon with us.
Sonic: Well there are times when I want to just chill.
Spike: Oh.
They arrived to the Wonderbolts Academy and what they was tons of ponies flying. The gang saw Spitfire talking to a familiar pony.
Sonic: Who's that?
Rainbow Dash: Oh great it's her.
?: *turns around* Well, well, well, if it isn't Rainbow Dash.
Rainbow Dash: Hello Lightning Dust.
Lightning Dust: As I was saying, please let me back in the Wonderbolts!
Spitfire: No.
Lightning Dust: Let me just prove myself give me a test a challenge anything just let me be a Wonderbolt again.
Spitfire: There's really no real test to give you.
Lightning Dust: Wait, wait, maybe I can, *looks around sees Sonic* hey your that hedgehog right.
Sonic: Yeah.
Lightning Dust: Spitfire if I could beat this guy in a flying race then would you let me back in the Wonderbolts.
Spitfire: Well that all depends Sonic do you agree to a flying race.
Sonic: Sure sounds like fun.
Spitfire: Looks like you get your shot. I'll go set up the race.
Lightning Dust: Yes!
Applejack: Whoa there partner you think this is gonna be easy.
Rarity: Quite right Applejack, Sonic even beat Rainbow Dash in a race.
Lightning Dust: Well that's a little disappointing Rainbow Dash to lose like that.
Pinkie Pie: Hey give RD some credit I mean Sonic is the fastest thing alive.
Lightning Dust: On the ground lets see if that hedgehog can truly handle the air.
The former Wonderbolt flew away with a smirk on her face.
Rainbow Dash: Sonic take her down.
Sonic: It will be my pleasure.
Everything was set up and all of the Wonderbolts were here for this race.
Spike: This is gonna be awesome.
Rainbow Dash: Yeah, not as awesome as the race me and Sonic har but this will be a close second.
Spitfire came in front of Sonic and Lightning Dust beginning to tell them what to do.
Spitfire: Okay racers all the way to the mountain and back.
Sonic: Mountain? *Barely sees it* Hmm seems easy enough.
Lightning Dust: It will be for me you can't even fly.
Sonic: So you say well get ready for *transforms* Super Sonic power.
Lightning Dust: Neat little trick but that won't help you.
Spitfire: Okay on your mark, get set, GO!
Lightning Dust and Super Sonic were off and both were at a equal speed.
Lightning Dust: Looks like we are equals.
Super Sonic: Oh we started, alright then see ya.
The super hedgehog easily passed Lightning Dust leaving her shock. She tried her best to try to catch up back to Super Sonic but he kept on getting faster each time.
Lightning Dust: How is anything that fast *sees the mountain* uh oh got to think of something.
The Pegasus saw a flock of birds flying and decided to create a tornado to make them in danger. The birds lost control of their flight pattern and began to plummet to the ground.
Super Sonic: Oh no *flies back to save the birds*.
Lightning Dust: That should keep him busy *makes it to the mountain* time to win this.
Lightning Dust went her hardest on that tornado thus making both of her wings sore. She ignored this thinking it won't be a problem but it was, all the flying she did mixed with the sore wings caused ber wings to break. She was now falling she thought this was it but she was wrong again. Lightning Dust was saved by Super Sonic.
Super Sonic: You ok?
Lightning Dust: You saved me?
Super Sonic: Yeah it's what a hero does.
Super Sonic was able to carry Lightning Dust back to the Wonderbolts Academy. Everypony who was there was able to watch Super Sonic carry her back.
Super Sonic: Alright I'm about to put you down.
Lightning Dust: Thank you, now go finish this race.
Super Sonic just took a step and he won the race everypony was cheering and the Mane Six, Spike, and Spitfire went to check on Lightning Dust.
Spitfire: Lightning Dust you ok?
Lightning Dust: I'll live, listen I tried to cheat and this is what it got me I don't deserve to be a Wonderbolt.
Spitfire: Well seeing that you see the errors of your ways we could give you another chance. Wonderbolts take her to a doctor.
Lightning Dust: Really, awesome and the moment I get better I will be flying with my boyfriend Sonic.
Super Sonic: Say what now?
Lightning Dust: *Winks at Sonic* See ya hedgehog.
Spitfire: Well Sonic the Hedgehog you are officially a Wonderbolt.
Sonic powers down.
Sonic: Sweet.
Spitfire: Your co captain to Rainbow Dash's team.
Sonic: Cool right Rainbow Dash.
The Pegasus wasn't happy at all, she was angry at Sonic becoming Lightning Dust's boyfriend.
Sonic: What's wrong.
Rainbow Dash: Since I'm head captain I want you to explain to me what you are Lightning Dust doing together.
Sonic: Listen Rainbow Dash she was just umm ohh your gonna hurt me anyway are you?
Rainbow Dash: Duh.
Spike: Start running Sonic.
Sonic transformed back to Super Sonic and flew away with Rainbow Dash following him.
