There are six criminal organizations.
Team Rocket, Team Aqua, Team Magma, Team Galactic, Team Plasma, and Team Flare. Tensions are high between them. Civil wars erupt between regions and endanger the lives of thousands of innocent people, all for one purpose. They are all trying to destroy each other in order to remain the only terrorist organization standing so that they may force their ideals on the public and achieve their ultimate goals.
Although their intent isn't to destroy the world, chances are unprecedentedly high unless they are put to an immediate halt. Will somebody rise up to teach these villains a lesson, or will the world be subject to destruction and chaos for all of eternity? It is up to you. Will you Unite with one another for the greater good of humanity or will you fall subject to the evil side of things and try to rule? There is no such thing as fate, only decisions. Either way, you will end up United against a cause one way or another. Welcome to Pokémon United.
