Ghetsis is one of the executives of Team Plasma, and the main antagonist of Pokémon Black and White. He is notable for being the only Crime Syndicate Executive from the main series of Pokemon games who serves as the final trainer of the game, as opposed to the usual Champion. He has a son name N (Pokemon)
Ghetsis's personality seems to be that of a kind, gentle man. As the game progresses, he gradually reveals his true personality: that of a cruel megalomaniac who will stop at nothing to get what he wants. He has no qualms in using the innocence of N for his plot to rule the world.
Contrary to many of his speeches, he views Pokémon merely as tools, thinking them too valuable to be lost. He has great charisma, as he was capable of convincing the members of Team Plasma, including the Sages to follow his ways. His charisma is demonstrated as many people are somehow influenced by his speeches, making them to at least rethink the relationship between Pokémon and Humans. Despite his villainous goals, this marks the first time the discussion of Pokémon rights and freedoms have been thoroughly discussed in-game.
