Based on the movie: Sonic the Hedgehog, but with some changes.
After fleeing to planet Earth, Sonic the Hedgehog has been secretly living in Canterlot City as his new home for the past decade along with his incredible power of super speed. Things went well for him, until he accidentally knocks out the power grid, getting the attention of the military organization, G.U.N., along with the evil genius, Dr. Robotnik.
Meanwhile, the Equestria Girls was preparing for their upcoming graduation, leaving Sunset Shimmer unsure of her future. When the power grid near their school was knocked down, CHS was in suspicion by G.U.N., sending in a special agent to investigate as a result.
When the two groups meet up due to circumstances, Sonic and The Equestria Girls must team up to retrieve Sonic's rings and stop Robotnik from using Sonic's power for world domination while fleeing from the government.

FEATURED: 10/10/20 - Awesome! 
Thank you all so much! 
This story now has TV Tropes page! 
So far, so good! =D Awesome for a sonic fan my self!
This looks like it should be fun. I loved the Sonic movie.
Crazy Carl 2.2! Yay! Just what I was looking for!
Perfection! I did catch up on the refence of sonic and the secret rings! I can't wait for more!
I think it is hilarious that Lyra is the “Crazy Carl” here, considering that in the fandom her character for years was based on making conspiracies around humans. Now she has another conspiracy.
Love all of Sonic’s nicknames for the girls.
So Lyra is “Crazy Carl”? I like it😏
I was smiling all the way through the chapters as I read them! :D It was a real pleasure to proofread and help you out! :D
REALLY good job on this chapter. Admittedly, I know you're being faithful to the actual movie at this point in time, but, all the same, I enjoyed the exchange, characterizations, action and future chapter set-up in all the right places. Enjoyed the heart-warming scene between Sonic and Longclaw before the Knuckles Clan attacked (though, yeah, I admit that while I think the actual Knuckles might be a good eventual Token Good Orc to his clan I can also understand that it's probably better to focus on one major villain at a time [as the better super-hero movies have taught us]). And now, on to the next chapter.
Excellent job on this chapter. REALLY enjoyed the exchanges, characterizations and future chapter set-up in all the right places. Absolutely loved the detail of Sunset and Sonic being Pen Pals (though I wonder how Sonic would take knowing there is a girl [Rainbow] who is NEARLY as fast as HE IS) as well as the girls just hanging out and the stuff with Lyra. As you said, it definitely makes sense. And, of course, Sci-Twi DOES make a logical younger Good Counterpart to Robotnik when you get to that.
But, anyway on to the next chapter.
Again, this was a splendid job on this chapter. Absolutely loved the work that went into the exchange, characterizations and future chapter set-up in all the right places. And, yeah, I loved the dialogue concerning the movie choices as well as Sonic's reflections on the girls (including the nicknames). And, yeah, they ARE going to be meeting face-to-face relatively soon. And, yeah, if Robotnik and G.U.N. didn't have enough issues with Sonic, Sonic plus seven magic powered heroines is definitely going to be one MASSIVE headache for them.
Anyway, very definitely looking forward to more of this.

Thanks again for your help with the proofreading! You are awesome!

Aw, shucks. Thanks.
wow. really hitting it with sonic from the movie here dude. nice and sad all at the same time.
All I can say is that this story have potential. While it is an adaptation of the Sonic Movie (best video game movie with Detective Pikachu
), I really like how Sonic and Sunset are pen pals and also Sonic helps Sunset cheer up somewhere after the events of the first Equestria Girl Movie, making a driving force for her to start over. Overall, I’m looking forward for the next chapter for this story have so many potential.
Couple of misspells here and there, but overall Im an instant fan and am PRAYING this doesnt end up like every other Sonic fic that just dies never finishing the story... Seen that happen way to many times on this site.

Lyra as Crazy Carl just suits her so well!

Thanks!
Next chapter will be out next week!

Don't you worry! I have every intention of finishing this story!
10476979
Phew hehe. I shall sit here in anticipation then
That chilli dog certainly looks tempting.
Except for the olive, I can't stand them.

Nice to see you again Comickook! Hope you'll stick around!
Thanks for making my day
Interesting idea, also according to Tyson Hess the echidna that shot Longclaw was actually pachacamac from Sonic Adventure.
New story that looks interesting...
An adaptation to the Sonic movie but in the EQG world? Hmmmm.
10477684
You're welcome!
10477930
Oh wow, I did not know that! That was interesting!
Edit: I just included your fact while crediting you!

They said that the sonic movie would not do well but they were wrong and now finding it in Equestria Girls crossover makes it more awesome
I really like you added Sonic and Sunset being pen pals makes it more unique from the movie and it adds something nice between their friendship. What also like you added more to crazy Lyra than Crazy Carl got in the movie. The biggest problem with these kinds of fics is they tend to just copy what happen in the movie exactly with a few changes. What’s the point in reading the fic if they do that?. So I’m hoping you add more unique stuff to this and it isn’t a complete copy. I could see Robotnik also get interested in using the magic the girls have to power his machines for example.

Agree with that, if anything, you can also add that Dr Robotnik also target the Rainbooms due to their magic being an anomaly that the government can’t describe and also the Rainbooms trying to keep their powers a secret too. That would bring the stakes to even higher.

Don't you guys fret! While I'm being faithful to the original movie, I'm also putting my own spin into this story. So there will be some differences along with some original scenes.
Haha, I've finally found someone else that uses "Skittles" as a nickname for Rainbow.
“I hear ya Rarity,” said Brainiac. “I’m more into Sci-Fi films myself, but unfortunately, it was Rainbow's turn to pick.”
That’s weird doesn’t Twilight like Daring Do?
Liked the nicknames Sonic gives the girls, so Sonic does know about Equestria. I wonder if He knows Pony Twilight?
But why did Knuckles' clan attacked Sonic and Longclaw? Do they know Sonic can use Chaos Control, but haven't found the Chaos Emeralds yet?
Geeze here I thought Scratch and Grounder have hard luck catching Sonic, but Lyra had it even rougher. She's been trying to catch Sonic for years ever since she was in the 2nd grade and our blue hero somehow makes her look like a complete laughingstock.
Pretty soon the world will need a hero and Sonic is that hero.
After reading the prologue, now I'm starting to like yours more than my version! Keep up the good work!👍

That what everyone want to know too. Hopefully the sequel to the movie will provide some answers
10480437
More.

You made a very good point, so I just altered her dialog.

At the beginning of the movie, Sonic narrates that everyone was chasing him because of his power of super speed ever since he was born. Whether the Knuckles Clan was after him for his speed or something else altogether, I'm not certain. All I know for sure was that they attacked him and Longclaw because Sonic unintentionally led them all to them after he ran out and grabbed a sunflower for Longclaw.
I watch the movie and it was great. even people think it said it okay but I think it awsome.
nice to see this story is going strong.
I’m aware of the Mushroom Hills zone from the games, but I also figured that the way Sonic always talked about hating mushrooms was meant to be a jab at his video game rival Mario.
Another fun chapter! :D Twilight aka "Braniac" is onto Sonic!
And he's decided to go to a baseball game. This can only end well. 
I can see Sonic being a TMNT fan.
Definitely loved this latest chapter. The exchanges, characterizations and future chapter set-up are all really well done in all the right places. I really loved Twi's preparations for that investigation stake-out, as well as the reactions to the speeds Sonic was reaching when going for the chili dogs. And, yeah, Twi DOES have a point concerning the investigations to either prove or disprove rumors. And, in addition to the Sonic Mythology Gags you mentioned in the author's notes, the preparations for Twilight's investigation DO sound a lot like her pony counterpart's efforts to investigate Pinkie Sense. Anyway, the comments about her "borrowing that older model radar gun without asking" were kind of amusing with the reasoning that 1. It was for science, 2. It WAS an older model, so her brother wouldn't miss it and 3. she was fully planning on giving it back after she was done (then again, this is a gal that likes to sneak her dog into school even when it's against the rules). And, yeah, now Twi DOES have one of Sonic's quills. And, Rainbow is probably going to get her chance to test her speed against Sonic's by the end of the story.
Anyway, definitely looking forward to more of this.
Ooh yes he will. Also, more refences! Can't wait for next week!
The bad thing about this story I dont like... Is that I have to wait every Saturday for an update! I really needed to see what happened next all week!
