In ancient times, a meteor fell upon the Earth, leaving a large impact crater, and bringing with it something awful that the ancient people cam to call the Great Poison. This Great Poison was a radioactive substance that, best case scenario, heavily corrupted any organic material it touched, and, worst case scenario, killed the organic material it touched. The legendary Pokemon came together and combined their powers to quarantine the Great Poison in the crater, where there was no organic material for it to corrupt. Now, thousands of years later, a criminal organization known as Team Corruption wants to harness the corruptive powers of this Great Poison, and use it to create an army of corrupted Pokemon to take over the world. Thousands of Pokemon have already died due to Team Corruption's experimentation. The fate of the Pokemon world rests in the hands of a group of Pokemon trainers. Twelve Artifacts are the keys to unlocking the crater. The heroic trainers must race against team Corruption to collect these Artifacts, unlock the crater, and vanquish the Great Poison from the Pokemon World for eternity.
