There are a lot of thieves and evil doers in the Pokemon regions, the organizations are usually in the form of teams or groups. The first evil team has bases in the Kanto and Johto regions, they are known as Team Rocket. Team Rocket is the most famous out of all the groups for sure. Scientists in their evil team are responsible for the creation of the mighty Mewtwo, the Pokemon created from the legendary Mew DNA. The goals of Team Rocket are basically to take over the world by any means possible. Famous members of this team are Giovanni of course, he is the boss. Jessie, James, and Meowth are probably the most famous in Team Rocket, they are trying to steal Ash’s Pikachu, and it seems they will never give up. Team Rocket is and always will be one of the most notorious Pokemon organizations.
Next is Team Magma and Team Aqua, they are both evil teams in the Hoenn region. Team Magma has goals to capture Groudon, an ancient Pokemon and use it to expand the land mass and create a better environment. While Team Aqua is trying to capture Kyogre, an ancient Pokemon and do the exact opposite of Team Magma and expand the ocean to create a better environment. Team Magma is led by Maxie while Team Aqua is led by Archie. Team Magma usually uses Numel, Poochyena and Zubat and their evolved forms. While Team Aqua uses Carvanha, Poochyena, and Zubat plus their evolved forms. They don’t have much of a difference Pokemon wise. But a huge difference involving their evil plots.
Team Galactic is up, they are the evil organization in the Sinnoh region. The team is led by the evil Cyrus. Cyrus has no emotion and wants to create a new world using Team Galactic. His goal is to get the red chain by capturing Uxie, Azelf, and Mesprit. He also must get his hands on the Lustrous Orb and Adamant Orb to call forth Dialga and Palkia. He and his team will travel to the Spear Pillar and call forth Dialga and Palkia, he will use the power of the red chain to take control of Dialga and Palkia and shape his new world. Dialga is the ruler of time while Palkia is the ruler of space. Team Galactic’s plans are more precise than the other teams.
The new evil team is Team Plasma. Their goal is to separate humans and Pokemon as in make the world Black and White. Separating them into two groups, not much is known about Team Plasma because they are the new evil organization in Pokemon Black and Pokemon White version.
