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.

This story now has TV Tropes page!

Long story short, I was a brony. I woke up one day to find myself in Spike's body. Dream come true, right? I'm in Equestria, I could interact with my favorite ponies, etc.

Well, as it turns out, I just happened to wake up right at the beginning of Season 1. Which could only mean one thing: I can change the future of Equestria. I could solve problems prematurely, prevent disasters from happening, and keep Twilight from going insane.

So now, my mission isn't to hug my favorite ponies, but to make sure everyone gets a happy life.
