Another story in the CiM universe, created by Spectrum Sparkle, and written as a collaboration between Spectrum and myself. This story takes place after "The Sonic Rainstorm," but before "Fluttershy's Return."

Tired of his defeats from Sonic the Hedgehog, the meniacal Dr. Eggman formulates the ultimate plan. By using a dangerous new force called Dark Energy, he vows to destroy the blue hedgehog once and for all. Along the way, he'll soon discover a new location to build his evil Eggman empire...Equestria. Will Sonic and the mane six be enough to stop this menace, or will the fate of Equestria crumble beneath their hooves?

Takes place after the events of Sonic SATAM.
During MLP:FIM season 3

Now with Robotnik gone, all that's left is to fix the problems he left behind, the main issue being his robot slaves. When finding a description about a lost civilization within the computer Nicole, Sonic searches for what's left of the empire known as, Equestria, in hope of finding anything that might help with his problem. Things would go a lot more smoother if Naugus didn't interfere.

The ponies are anthro (just like Sonic).
And Sonic's personality will be that of the SATAM series.

Stumped on the mystery of the locked box, Twilight begins to get frustrated. When Princess Celestia suggests to Twilight to visit her old castle, she jumps at the opportunity to make any type of progress. Little did she know she would get a lot more than she bargained for...

Basically this story is a mix between Castle Mane-ia and Bats!, but with a dark and interesting twist. Join Twilight and her friends as they brave the thousand-year-old castle and unearth its ancient mysteries while escaping a sinister, unknown threat. Will the ponies be able to escape the clutches of darkness? Or will they be morphed into a shadow of their former selves?

Original story idea by DarknessRising

When Rainbow Dash wakes up to find herself sharing a bed with somepony—or rather, somedragon—she knows she's going to have an eventful day. Determined to put the whole ordeal behind her, she agrees with Spike to forget the evening had ever happened.

However, things have a way of coming back to haunt you, and for Rainbow Dash, it may not be what she asked for at all.

Group collaboration between the lovely members of SpikeDash:

(Current undergoing revision)

In the aftermath of the Mare-do-well incident Rainbow Dash has dissappeared from Ponyville and only Twilight and the other Elements may have a clue of where she went, but they aren't talking.

Meanwhile, Rainbow Dash is in for the race of her life when she goes up against the fastest thing alive...Sonic the Hedgehog on the orders of Dr. Eggman/Robotnik.
