Team Rocket has expanded into the new region of Yesera, gaining unimaginable numbers and power. They have created a device that, when given to a pokemon, gives it power double that of a normal pokemon. While this device strengthens the power of the pokemon, it eventually drains the pokemon of all power. When all of it's power disappears, so too does the pokemon.
Professor Maple has been studying Team Rocket and their new device but has yet to actually acquire it. She believes that their plan is to find a pokemon immune to it's diminishing effect no matter how many pokemon die off in the process. The professor has sent out a notice in town to search for trainers beginning their journeys that would like to aid in her research. Those willing to help would receive a starter pokemon from Professor Maple.
The journey will not be easy. Many will fail along the way. Will you choose to help stop this mass extermination of pokemon? Or maybe you wish to breed pokemon to bring out their strongest stats.
