Original Description:
 
With Fluttershy, Applejack, Twilight, Rainbow Dash and Rarity incarcerated and out of the way, Equestria’s new rulers turned their attention to the final and most feared member of the Mane Six: Pinkie Pie. Twilight had a god-like mastery of magic, Rainbow Dash was the fastest pony in Equestria, and Applejack’s strength was a sight to behold, but Pinkie… Equestria’s rulers were terrified of Pinkie. Her reality-warping powers were beyond their comprehension and threatened to undo all their plans.
 
Then, musing on their success with the others, they realized that Pinkie might be one of the easiest to take care of.
 
Approaching Pinkie, her soon-to-be-jailers made her an offer. Equestria was running dangerously low on energy, and only her maniac energy could help save it by powering up a reactor core. Thus, if she spent a week powering it, she would then get to spend a week partying non-stop, and throughout it all she would be permanently and irrevocably locked into a sack that would contain her for the rest of her life wearing a super-happy fun sack that would allow her to contain her energy and keep her safe.
 
Needless to say, Pinkie eagerly accepted.
 
In the years to come, Equestria’s rulers, now the undisputed masters of their realm, were continuously astonished at how one pony could generate so much energy to power their new empire. The longer Pinkie partied, and the more time she spent inside the reactor core, the crazier and more powerful she became. So powerful, in fact, that after a few decades she was able to power the entire planet by herself. And thus everyone lived happily ever after.
 
The End.
 

 
Well, that does it for the coup series. Thanks again to Takugenji for giving me the idea to do pictures for each of the Mane Six. And huzzah, this is the 100th permanent bondage pic on Derpibooru!
