Ghetsis

Ghetsis is the true antagonist in Pokemon Black and White, as well as the father of N. He is one of the Seven Sages of Team Plasma. All along the story, he pretended to serve N and to fully support Team Plasma's utopy, though he often lets slip that he serves his own interests. In fact, his true goal is to be the only person in Unova to have Pokemon, so that he would be able to take over the entire land. To do so, he manipulated his own son as a puppet-king of the Team to make him capture Reshiram or Zekrom, so that he would be able to use them.

Gameplay
He was first seen in Accumula Town talking to the locals that they shouldn't enslave Pokemon. You encounter him several times telling everyone to send their Pokemon to Team Plasma to be released back into the wild. After the player beats N in his castle, Ghetsis will come up and say that N was a disappointment losing to the player, and it was revealed that Ghetsis was using N for his own evil deeds, calling him a good-for-nothing boy, warped, and defective.. After that, he will battle the player in a rage. His choice of Pokemon are; Cofagrigus, Bouffalant, Seismitoad, Bisharp, Eelektross, and Hydreigon. When defeated, he will be taken away by Cheren and Alder. After that, it is revealed that he was safe because of the help of The Shadow Triad, his most faithful and loyal servants.

In Pokémon Black 2 and White 2, Ghetsis is the leader of a new Team Plasma. This version of Unova's villainous team is not attempting to release Pokémon, but instead take over Unova.

Trivia

 * It's unknown if Ghetsis really is N's father.
 * His strongest pokemon is a Hydreigon at level 54. However Hydreigon's previous evolved form; Zweilous evolves into Hydreion at level 64, so his Hydreigon is underleveled.
 * Ghetsis is the only antagonist that uses a Pseudo-Legendary Pokemon during the final battle with the main hero.
