Set in an alternate universe where ponies discovered technology and "put it to bad use" is an understatement, the small filly Sweetie Belle (who has a different personality in this universe) decides to make things right. With the help of **** ***** *** *******, she will face the Mane 6. Well, only some of them due to some of them ***** **** and one being *** **** ****.

WARNING! IF THIS FANFIC WAS A FILM, I WOULD BE A 12A!
