Once upon a time Pokemon and people shared one single world together. They lived together, but they in fear of each other. Most humans feared the limitless power the Pokemon had. In fear, they attacked Pokemon and found a way to enslave them. With their new found power, some people became corrupted. Those humans became more and more power hungry. They would try to enslave more powerful Pokemon to overpower the rest. They used the Pokemon they obtained to kill other Pokemon and humans that got in their way. Many horrible things were done to Pokemon to ensure they obeyed. Many humans were corrupt, but some fought against their corruptions.
There were humans that have befriended Pokemon. They were small in numbers but could coexist with Pokemon. They believe that Pokemon shouldn't be enslaved and their respect should be earned. They protected their friends from the corrupted. Soon the corrupted wage war against the peaceful humans. The war killed many people and even more Pokemon. The world balance was tipping over, until one day the world was split into two different dimensions. They still existed in the same world, but the dimensions made it so then Pokemon lived in their own world and human lived in theirs. Occasionally, the dimensions would merge and link the two worlds, but for the most part, they remain separated.
The Pokemon world had been thrown into chaos by then. Some Pokemon had lost all self-control, and strange ever-changing labyrinths appeared. All the Pokemon blamed the humans for all the suffering. They believe one day the dimensions will link the two worlds again, and the humans would try to enslave them again. So they created an enormous Pokemon army that spread far and wide. There was a Regiment in every village or town. There was one in the sea, one high above the clouds, one in a volcano, one underground, and lastly in a great forest. They were all connected as one big army.
A young piplup, that grew up in a village deep in a forest, dreamed one day joining Lucario's Regiment. He wanted to be a big hero and put an end to Pokemon suffering from humans, thus he wakes up to a brand new adventure.
