N is an enigma of a character who was first introduced in the Black and White, or Fifth generation, Pokémon games. He is one of the rival characters to the player character in the Pokémon games, and appears numerous times to battle with the player. N is an idealistic activist that has adopted the Team Plasma philosophy of releasing Pokémon from human control, due to humanity’s constant abuse of Pokémon and their powers for battle and other practical uses. N’s ideal goal is to create separate worlds for both Pokémon and humans.
N has the ability to sense a Pokémon’s feelings and thoughts along with hearing their "voice." He has a very intuitive relationship with Pokémon, more so than he does with actual human beings. N also has an obsession with mathematical formulas and how they work together so cohesively to create many things. In fact, one of his favorite things to do is riding Ferris wheels, simply because he loves how all these different mathematical formulas come together to create a beautifully synchronized circular motion in the Ferris wheel.
He later reveals himself to be the leader, or "King," of Team Plasma at the Nimbasa Amusement Park to White(Manga) and to the Player (BW Games) in an attempt to distract White/The Player as some Team Plasma members escape. N becomes the primary antagonist for a majority of the story, as Team Plasma advances in their goal to release all Pokémon from human control.
