Pokécalypse

A world that has long since fallen to ruin, humanity and most pokemon struggle surviving here. Nature is starting to take over, but with the harsh climate and weather, even that is struggling. Yet, some Pokémon have made it their mission to hold onto hope -- to try to heal the world back to what it once was, as best they can.
While others thrive in the harsh conditions, some have mutated to better fit this new world, and some have even become corrupted and unnaturally violent.
