The Pokémon Foundation (Pokémon Horror Story)

It's been a couple years since the great plague invaded the world of Pokemon. A plague, where no one's been the same since. Not only did thousands of people and pokemon die, suffering this awful plague...But most pokemon became monsters...mutants you could call them.
What used to be loveable, fun-loving creatures, turned out to be rabid, killing machines...There was now a world filled with these Pokemon Mutant Creatures hurting and killing everything and everyone that was left alive.
That was until Officer Jenny and her police squad did everything they could to capture these mutants and placed them in an abandoned pokemon lab where they will be tested to see if the effects of the plague are irreversible.
The professors and Nurse Joy also helped to figure out what went wrong and what the hell had happened to what used to be these free spirited pokemon that people loved so much...who now turned out to be feared by everyone.
After years, most of these creatures being caught, the world did its best to go back to normal. There were construction crews fixing everything the creatures had destroyed, while people did their best to move on and live their lives...
Celesta Riley however had just moved to the city, hearing about these mutated pokemon and wanted a job to figure out what went wrong and if there was anything she could do to help. Celesta felt bad that these harmless pokemon had to suffer such a fate...
But what happens when she begins to work and the power suddenly goes out? What happens when the backup generator fails and these Pokemon Monsters can now escape? Your only choice now is to either run, hide or fight...what will you decide?
