Hey guys thecoolj here just got to say sorry for the long wait just busy with school and wrestling got fourth place in county. Anyway this story was wanted by 2 guests and epic rainbow 22. I own nothing half Sega and half Hasbro.
In Ponyville it was nighttime and everypony was celebrating Nightmare Night. Twilight was getting ready for this event by wearing her Star Swirl the Bearded costume again, while explaining Sonic how this event works.
Sonic: So wait little ponies dress up in costumes, go door to door, just for candy.
Twilight: Yes that is pretty much it.
Sonic: That's cool! I mean free candy is free candy and you get to dress up.
Twilight: I knew you would love it. You know Sonic you should go to Rarity she might make you a costume.
Sonic: Sounds like a good idea.
The hedgehog was on his way to Rarity but he felt a pain in his body. Sonic fell to his kness and groan in agony. It took a while but he realized what was happening so he went off to see Princess Luna. Sonic went to the place where he first met the Princess and right there she was there.
Sonic: Princess, Princess Luna I need your help?
Princess Luna: Sonic I know why your here.
Sonic: You do?
Princess Luna: Yes, you see I am one with the moon and when we first met I felt your connection with the moon.
Sonic: Oh I see but why is this happening only on this night?
Princess Luna: I have a theory, on this night I feel my power grows stronger so I think on this night the extra power is also given to those with a connection to the moon.
Sonic: Hmm seems about right so I should go with it.
Princess Luna: Yes by tomorrow you should be okay.
Sonic: Alright time to be Unleashed again.
The blue blur decided to stop fighting the power within himself and let it be one with him. His transformation had begun he gained more muscle mass and weight, he chest got broader, his arms grows larger, his hands got larger and his nails becomes claws tearing off his gloves, his muzzle grows larger, his teeth became sharp and pointy, his ears bacame more curved, his fur turned to a gray/dark bluish color, and the bottom of his shoes becomes covered with small metal spikes.
Sonic: It feels good to be back.
Princess Luna: Amazing.
Sonic: Well I'm going to Ponyville see ya later Princess.
The werehog rushed back to Ponyville on all fours and before anypony could see him he decided to have a little fun. He decided to stay in the shadows so nopony could see him, meanwhile the mane six and Spike were in Golden Oaks Library trying to figure out were Sonic was.
Twilight: Rarity are you sure Sonic didn't stop by at your place.
Rarity: I'm positive Twilight.
Rainbow Dash: Guys quit worrying this is Sonic we're talking about.
Applejack: Yeah no one is tougher than Sonic.
Right at that moment bursting through was a creature the ponies and Spike had not ever seen before. Everypony screamed at the top of their lungs and Spike just fainted, the creature then fell down laughing leaving the ponies confused.
Sonic: Haha that was so cool.
Pinkie Pie: Um scary monster aren't you gonna you know finish us off?
Sonic: What, no girls it's me Sonic.
It took some time but they realized that it was their fun loving hedgehog.
Fluttershy: Sonic as a friend NEVER DO THAT AGAIN! Oh I'm sorry didn't mean to yell but please never do it again.
Rainbow Dash: That was incredible Sonic you actually got them scared.
Applejack: Um Rainbow Dash correct me if I'm wrong but didn't you have a tear in your eye.
Rarity: Sonic what happen to you, you look like a beast but you make it work.
Sonic: Thanks but this is a one time transformation.
Twilight: What do you mean?
Sonic: Had a talk with Princess Luna, connection with the moon, werehog transformation, back to normal the next day c'mon ponies lets go have some fun. Oh and wake up Spike.
The gang decided to go to the center of town to celebrate this night. On the way there Sonic was explaining everything about his werehog form.
Rainbow Dash: So wait you lose your speed?
Sonic: Yup.
Fluttershy: Doesn't that mess you up in battles.
Sonic: Nope ya see in this form I don't need speed when *flexing* I'm rocking these bad boys.
Rarity: Well your right those muscles are *blushes* incredible.
Applejack: They sure are.
Everypony was swooning over Sonic's muscle making Spike jealous. As they arrived to the center of town they saw ponies screaming in terror the reason was the Diamond Dogs.
Rover: Get out of the way mules!
Spot: You sure gems are here?
Fido: I sure I have a sense about these things.
Sonic: Umm what the heck are those things?
Rarity: Diamond Dogs Sonic.
Sonic: Diamond Dogs?
Rarity: Nasty, ugly, disgusting, ugly, mean, ugly, rude, and did I mention that their ugly.
Rainbow Dash: You don't have to.
Sonic: Guess when they heard of a ugly stick they fetched for that first.
The Diamond Dogs heard the insults and were preparing for a fight.
Sonic: Okay guys get out of here I got this.
Twilight: Sonic you sure?
Sonic: Twilight I got this now go.
The ponies and Spike listen to the werehog and left him to deal with the Diamond Dogs.
Rover: Well look what it is a fuzz ball with a big mouth.
Sonic: Fuzz ball? Okay I'll pretend that is insult.
Spot: This is gonna be fun looking for gems while we take down some chump.
Fido: Real fun, so who gets first hit.
Sonic: I guess that would be me.
Sonic stretched his arm and delivered a punch straight to Fido. Rover and Spot quickly went on the attack but Sonic attacked with his claws sending both dogs in opposite directions. The three dogs knew that this would be trouble so they called up all their whole team. Sonic wasn't intimated by this he only smiled.
Sonic: Alright mutts are we gonna fight or are you kittens.
Fido: What!
Spot: He-he-he just called us kittens!
Rover: Break him BREAK HIM!
All the Diamond Dogs rushed and dog piled Sonic. They had thought they won but were shocked when Sonic used brute force to throw toss them all off.
Fido: Forget this I'm out of here!
Rover: Me too!
Spot: Out of my way me first me first!
All the Diamond Dogs fled in fear with Sonic laughing as they left.
Sonic: Well that's taken care of now come on everypony lets party!
Twilight: Wow that was amazing Sonic, would you like to dance?
Rainbow Dash: Whoa Twilight what do you think your doing?
Rarity: That's right Sonic is gonna dance with me.
Applejack: Wrong he's dancing with me.
Pinkie Pie: No way Sonic is gonna dance with me.
Fluttershy: Um girls I think Sonic would be happy to dance with me.
Spike: Luckiest guy in the whole world.
As the party started back up the Mane Six still argued about who Sonic was going to dance with, leaving the werehog embarrassed.
Well that's the end again sorry for the wait hoping to make the next chapter faster. Well you know read, review, make ideas for more OVA's, and be cool see ya next time.
