N

"You're looking for Team Plasma, right? They ran into the amusement park. Come with me. They're not here. Let's ride the Ferris Wheel and see if we can spot them. I love Ferris Wheels. the circular motion... the mechanics... they're like collections of elegant formulas."''"

- N

Natural Harmonia Gropius (ナチュラル・ハルモニア・グロピウス) commonly known as N (エヌ) is a major antagonist of the Black and White versions. His full real name is never directly revealed in game, but his surname is (as revealed by Ghetsis between the final two battles against them, the name is first discovered written on N's basketball in his playroom) Harmonia. He is the leader (or, as said by Team Plasma members, the king) of Team Plasma.

In Pokémon Black 2 and White 2, he returns two years later, coming back to stop Ghetsis' new plans with and renewed Team Plasma.

Background and Story
Prior to the events of the game during his early childhood, he was forced by his father to grow amongst abused Pokémon, thus growing resentful of humans. N then decided to become the "hero" of a Unova legend, a hero who once along the Legendary Pokémon (Either Zekrom in Black or Reshiram in White) fought many battles against people who stood against his views and successfully managed to unite people's hearts thus creating the Unova region.

Later on, after he has grown to his current age Ghetsis asks him for his help to separate Pokémon from humans, which he agrees to and is crowned King of Team Plasma by Ghetsis.

A certain time after that he's present during Ghetsis's speech about Pokémon and humans in Accumula Town, and when he and his subordinates leave, he talks to the player's Pokémon and asks it about its thoughts. Not given the answer he expects, he decides to battle with his only Pokémon, after which he retreats.

He's later seen in Nacrene City after the player tries to enter the museum. N shows himself and decides to challenge the player with a completely new Pokémon team, however he is unsuccessful and leaves seeking more powerful "friends" to help him.

The third time he is seen is in Nimbasa City in the amusement park, where he invites the player to go with him to the ferris wheel, showing a childish personality for the first time. When the two of them enter the wheel, N reveals his status as the King of Team Plasma, and what his objective is. After descending from the wheel N and the player are interrupted by Plasma Grunts, who are looking for their "lord". N promises them that he will bide time to let them escape and battles the player a third time. However he is once again defeated and claims that he is going have the power of the Legendary Pokémon and challenge the Elite Four. He taunts the player, saying if you want to stop him, to collect all eight gym badges and go to the Pokémon League.

N is later seen in the Chargestone Cave, revealing his personal guard the Shadow Triad, three members of Team Plasma sent by Ghetsis to protect N. They plague the player continuously during his travel in the cave by teleporting and forcing the player to go with them. The player is finally able to challenge N after passing through many Grunts in the cave. N challenges the player with his new team made solely of Pokémon found in the cave. N is defeated once more, while berating Pokémon Battles as they hurt Pokémon. Bianca and Professor Juniper soon show themselves, with the latter being questioned by N about how she can give Pokémon to trainers making them "suffer". The Professor only says that their views are different but equally respectable; N is furious and takes his leave.

He is seen again after the player successfully earns his 6th Badge. He talks to the first party member on your team that is not fainted, and is happy that the players Pokémon like him, although he's sad that good trainers like you will have to release their Pokémon, too.

At Icirrus City, at the Dragonspiral Tower, N is seen with Reshiram (White) or Zekrom (Black). He captures it, and tells the player to look for the Light/Dark Stone. He then flies off on the legendary dragon, vowing to defeat the Champion.

The next and last time he is ever seen is during the Pokémon League, in which N shows himself along with his massive Castle awaiting for the player who makes his/her way through some Grunts and six of the Seven Sages. You see him defeating the Champion Alder, and is pleased to see the player make it. He waits up in his throne, at the top of the castle. N will be sitting in his throne and will summon either Reshiram or Zekrom, but before they can battle, the other legendary Pokémon awakens to be faced by the player. After being successfully caught, the player faces N (either with the two Legendaries clashing or not). N will use a new and fully evolved team of six Pokémon. Even then, he is defeated and is soon confronted by Ghetsis, who reveals he is N's father and his true plot to rule the world by using N. After Ghetsis is defeated, Alder asks N if he's realised his mistake, however N doesn't answer. After Cheren and Alder take Ghetsis away, N talks personally with the player and walks to the hole that Reshiram/Zekrom crashed through and he throws the Poké Ball. The game ends with him saying "Farewell". After the credits, depending on which version (Zekrom on Black, Reshiram on White), Zekrom/Reshiram is seen flying in the sky, with N on it's back.

N is mentioned by Looker after all Seven Sages (excluding Ghetsis) are found and arrested. He says that N has been seen with the legendary Pokémon in a distant land.

Pokemon Black 2 and White 2
Two years later N returned with either Reshiram/Zekrom to stop Ghetsis,his new Team Plasma, and Kyurem from harm the Unova region. He later save the player from Ghetsis(Who tried to kill the player using Kyurem) using Reshiram/Zekrom. But Ghetsis anticipating N's arrival, used the Gene Wedge to fused Kyurem with either Reshiram/Zekrom to form Black Kyurem/White Kyurem. N begged the player to stop Ghetsis and Black Kyurem/White Kyurem. The player succed, Black Kyurem/White Kyurem splited in two, and N got his Reshiram/Zekrom back while Kyurem disapeared. Ghetsis angered that the player folied his plans challege him to a Pokemon battle. The player defeated him nontheless. After Ghetsis escaped with the help of his Shadow Triad, N thanked the player for saving Unova, he left flying away with Reshiram/Zekrom. After the player defeats the Elite Four and becomes the Champion, the player's Rival tells him/her about a random Zoroark being seen on the Victory Road. The player than follows the Zororark all the way to N's Castle. The player them meets N once again who follows him all the way around his castle. N then challenges the player to a battle with his Reshiram/Zekrom. After the player defeats the Dragon it turns back into either the Black Stone/White Stone.

Trivia
thumb|300px|right|Final Battle VS N and ending
 * When battled, N uses Pokémon that he happens to see and then releases them back into the wild after said battle, except possibly for his Klink.
 * N is the only Trainer to use a Legendary Pokémon on his team who is not fought in the Battle Tower or Battle Frontier, and also the only antagonist who suceeded into capturing a legendary Pokémon.
 * The object attached to the chain on N's pants is the first iteration of a Menger sponge. N also had the Menger sponge around his neck when he was younger.
 * N is the youngest Pokemon Criminal Team boss yet to date. The other criminal team bosses look as if they are in their 30's or 50's while N seems to be in his teen years.
 * When the English names of most characters were released, N and Cheren are the only ones to retain their names.
 * N's views comes from the fact he was only allowed to see injured Pokémon and was spurred by Ghetsis.
 * Young kid N has a resemblance to Tory.
 * N seems to talk quickly when you compare the text speeds from him and Cheren.
 * N's Pokémon in the final battle, excluding Reshiram and Zekrom, are more than likely Pokémon he played with as a child as none can be found in the wild. Proof of this is the fact he had a Zorua as a kid, and had a Zoroark, which is Zorua's evolved form, in the final fight.
 * He also refers to his last Pokémon as his "last friend", further supporting the theory that his Pokémon are his childhood friends.
 * As seen on his final battle, N captured Reshiram/Zekrom with a basic Poké Ball.
 * Strangely, in the first battle with N, his Purrloin knows the move Assist, which always fails unless another Pokémon is on the team.
 * Unlike other past villainous organization bosses, N works solely for the benefit of Pokemon, rather than seeking to use them for his own self-centered ends.
 * N's name comes from the phrase from the N64 "Get N or get out"
