Okay, here it is:
So, the RP would take place 50 years in the future of the Pokemon world we know today. It has become a place filled with destruction, as Team Rocket have risen to power, and are much different than they once were. They are doing things such as enslaving Pokemon and people against their wills, combining and mutating Pokemon to make new and terrible creations, and sending the world into chaos. Many people have decided to not resist them, as they believe they will be killed like the others. However, a few people refuse to let this continue...
So, basically, you get to be someone who is rebelling against the rockets. I was also thinking about letting people be Team Rocket members, and allowing them to rise in rank as the RP goes on. Maybe, they would even get to discover the true reason for Team Rocket's actions...
Sorry, I could have explained it better, but that's a brief summary of it. ^^
