Break the Walls Down

by Super Saiyan D
In an effort to rid himself of his mortal enemy, Dr. Eggman flings Sonic into another dimension. Stranded, alone, and with no apparent way home, can he survive this strange new world? What adventures await him? Come along and find out.

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.

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.
