Dr. Ivo Robotnik moves to Equestria intending to destroy it with missiles. He will work towards his goal until he has achieved success and will be able to promote himself once more!

Soon, Elvis Presley rules the land and a band of sudden heros strive to stop Robotnik, the Cutie Mark Crusaders join the Holy War, and Twilight Sparkle yells at SporeDragon through the 4th wall.

Will they stop him in time?

Warning, turns excruciatingly random closer to the end.

Crossover of My Little Pony: Friendship is Magic, and The Adventures of Sonic the Hedgehog.
