Long ago in a distant land, Ivo Robotnik, the egg-shaped master of science, unleashed an unspeakable evil. But a brave blue hedgehog wielding supersonic speed stepped forth to oppose him time and time again. Before their latest confrontation reached its climax, the villain tore open a portal through time and space, and flung him into another world where magic and fantasy are everyday reality. Now the hero seeks to return to his world, and stop the mad doctor from conquering this one too. Along the way he'll meet new friends, new enemies, and just maybe something a little more. All while the fate of two worlds hangs in the balance.

Hang on to your seats boys and girls, cause we're breaking down the walls between dimensions.

Now on TV Tropes.

After some inspiration from from my good pal Gunflame, I'm throwing my hat into the ring for a good Sonic/MLP crossover. And I aim to give it the much needed improvement in quality that's so desperately needed with this particular crossover genre. I'll strive to make this one of the premier Sonic/MLP crossover stories on the web.

Thank you and enjoy.

Twilight Sparkle, Equestria's newest alicorn princess, is an intelligent mare, and the most powerful mage alive. Thanks to her and her friends, the magical world of ponies is at peace. But in that peace, her entire life has changed, and Twilight is no longer certain of her place in the world. How unfortunate, then, that a past she's never known is about to come calling.

After a mysterious stranger attempts to steal Twilight's magic crown, she must travel to another universe to confront the thief. There, she finds a world where magic and friendship simply do not work, and a school full of powerful adversaries who stand between her and her crown. If Twilight cannot retrieve it, her failure could mean the destruction of two worlds...

A fusion fic with Kill la Kill.

Rated teen for violence, more violence, some blood, explosions, ponified cursing, and more explosions and violence.

A note: it's not just about who stole the crown. It's also about why.
