To fight monsters, we created monsters.

As senior morale officer for the Pan Equestrian Defense Corps at Ponyville Shatterdome, Pinkie Pie wants nothing more than to make the days happy for everyone. But then a young, enigmatic unicorn named arrives from Canterlot with bleak tidings, and Pinkie Pie finds herself pulled back toward a past she thought she had put behind her.

With the longest day of the thousandth year of Princess Celestia's rule approaching, the kaiju have only grown stronger and their attacks more frequent. No matter. So long as Pinkie Pie has breath in her lungs and people to please, Equestria will have its Summer Sun Celebration this year.

An adaptation of Pacific Rim for the world of My Little Pony.
