As a newly initiated Crusader, Rumble has become determined to prove that he can be anything, no matter what his future cutie mark says. But what will the mysterious addition of a horn say? It seems that Rumble's epiphany has brought out his true form as an alicorn, the first ever male one. And to the princesses, this can only mean one thing: Rumble must become Prince of Equestria! Now the scrappy young colt is thrown into a life of royalty and must carry out the duties of a magical dignitary. Can Rumble handle the stresses of being the first Equestrian prince?...Well? Can he?!
