Given the successful befriending of Discord, Princess Celestia deems that no longer will villains be defeated but instead reformed. While most have the chance to submit willingly or continue to fight, King Sombra is given little option. Brought back from the dead and stripped of all his powers and strength, it's all become a game of futility. Now Sombra only wishes he could have stayed dead all along.

“All unicorns build doomsday devices!” Those five words were words that Twilight Sparkle never expected to hear next to each other and in that specific order in a sentence.

King Sombra has returned, and upon discovering that Twilight Sparkle has not even considered building a doomsday device, has given her an ultimatum: Either she builds a device that has the sole purpose of destroying the world, or he starts defacing her books.

The clock is ticking: Will Twilight be able to get in touch with her inner mad science and save her imperiled reading material? More importantly, is she really destined to bring about the end of the world? Are unicorns really nothing more than a cosmic reset button, poised to bring a halt to all existence at a moment's notice even in the face of past evidence suggesting that they're not very good at it? Will Twilight succeed where all others have presumably failed? Does she even want to?

Join in as we follow the journey to answer the question on minds the world over: “Anypony for Doomsday?”

A millennium ago, give or take, Princesses Celestia and Luna were nearly defeated by the most powerful villain that they had ever faced, Grogar, the dreaded lord of Tambelon. Thanks only to the whims of random chance, the two princesses survived that encounter, but have been forced to live in fear of the time of his inevitable return. That time is now...

...But whatever revival was intended has gone a little... wrong. Behind the wheels of Grogar's body is the spirit of a slightly extremely eccentric human. Equestria would have been lucky to survive the real Grogar, but will the ponies fare any better with this loon ruling Tambelon?
