When Spike discovers a terrible secret about Princess Celestia, he decides to single handedly bring all four Alicorn rulers down. But to that, he'll need some help. So he redeems himself in the eyes of his kind, and leads them on a crusade against the ruling powers of Equestria in order to get the ponies of Equestria to see dragon kind as their liberators and benefactors.
Spike's plan closely resembles the plan of a certain Batman villain. . .
