Celestia is planning to have Discord reformed by the mane six, but before she even tells the girls, Discord returns seeking revenge by re-hiding the elements, as well as transforming Celestia, and the mane six. But unknown to him, a failsafe was prepared in this event by Celestia and Luna. Will they be able to stop him in time? I know, bad description. But I'm (hopefully) better at this fanfic.

First one. If it sucks deal with it.
Alternate universe tag for The Doctor. (Imagine bon-bon)

Note: This was written as an alternative to if something went wrong before he got reformed.
