PastN was raised to become the king of Team Plasma, awaken Zekrom, and free all Pokémon from the tyranny of trainers. On a rainy night the year before the opening of the BW Arc, N "liberated" a starter trio from Cedric Juniper, feeling that the practice of giving out sets of starter Pokémon created suffering. Snivy remained with N, but Oshawott went back to Cedric Juniper and Tepig vanished.
N makes his first appearance standing near an Xtransceiver commercial shooting after Black manages to save it from being attacked by a wild Galvantula. He sheds tears over the fact that Pokémon are being used for purposes such as acting.He later appears in Accumula Town where he states that Black's Galvantula is trying to speak with him when Black contemplates releasing it. Black immediately dismisses the thought of a Pokémon talking in a human language. N states that he feels sorry for Black because he cannot hear the voices of Pokémon. N asks for Black to battle him so that he can hear the voices of his Pokémon, and N easily dominates the battle with Purrloin.
When Black tells White he doesn't think he can win, N agrees, telling Black it is because he shuts his Pokémon in pokéballs. Purrloin scores a good hit on Black's Munna, and Black calls out his Braviary. With movements of his wrists, N summons a Pidove, Tympole, and Gurdurr wordlessly from apparently nowhere.
When Black pulls out his pokédex to try and get an edge in the battle, N immediately grabs Black's wrist, growing more intense as he yanks Black closer and tells him that many, many of his friends were locked into pokéballs to fill the pokédex.
N questions if Pokémon are truly happy when they’re locked up inside of pokéballs; he states that once a Pokémon is locked up inside of a pokéball then its voice is lost and he can longer understand them. He tells Black that he knows when a Pokémon attack will do the most damage and the moment it can happen, and that he should rely on his ears to listen to Pokémon rather than using a machine’s data.
He begins to tear up while stating that it is impossible for humans and Pokémon to be truly happy together and that they suffer because people cannot hear their voices. Black is angered and has his Tepig attack Tympole to show N his spirit. N has a moment of shock before Tepig's attack hits, knocking out both Tympole and Tepig and throwing Tympole and N into a wall. N tells Black that he heard Tepig's voice, presumably saying he loves being with Black. As he walks away from Black he says that he has found another unsolvable formula.
Black reveals to White afterwards that his Munna ate N's dream during the battle, and N's dream is a very gentle dream of his childhood.
N rescues the Team Plasma member that White and Black had in their custody, (temporarily) kidnapping White by trapping her in the Ferris wheel with him and a Servine so that the Plasma can make an escape. He sits with her in silence, fiddling with his menger's sponge, until his necklace—a communication device—buzzes or makes some sort of noise. He lifts it, speaking into it. It's the Team Plasma member he has rescued with a few teammates, asking if N is okay. N reports that he is okay and advises them to run away. Hanging up, he explains to White that by shutting her in here, the captured member can make a getaway. When White accuses him of being their teammate, he corrects her, telling her that he is Team Plasma's king.
He tells her that his goal is to save both Pokémon and the people who also save Pokémon, namely Team Plasma; he says that was what Ghetsis told him. N looks out the window, making a non sequitur comment that he likes Ferris wheels because of their peaceful, circular motion and the interconnection of their formulae. He asks White if she understands. When White responds that she doesn't—not just the Ferris wheel but more the liberation of Pokémon—N admits that perhaps he is the one who doesn't understand, saying he has watched her and her Pokémon Musical to try and understand, but has failed. He picks up White's Tepig, Gigi, who is terrified as he adjusts the bow on her head as he asks White why she is in showbiz. He listens without verbal judgment all through her explanation as she says her dream is to make Pokémon and people happy.
N is, however, unconvinced, and considering his silence, possibly uncertain of how to proceed. White says his thoughts for him, guessing that he believes that showbiz is only what humans do for other humans and Pokémon shouldn't have to be included. White tells him that there are Pokémon who enjoy it, and N surprises her by saying she is right. Just as some humans like drawing and others like running, some Pokémon like singing, dancing, and being on stage. But N points out that by favoring that one aspect of a Pokémon personality, to the exclusion of everything else, stunts their growth. Battling is how Pokémon grow and evolve naturally, as according to their species. By controlling them, humans take away the majesty of Pokémon.
N lifts Gigi, who is no longer afraid, and asks her if she would like to try battling—something she'd always been denied in BW Agency, and could only watch as Black's Tepig grew stronger and evolved. N asks if she would like to use her attacks however she wants and to taste victory.
Servine suddenly attacks Gigi, its tail slamming Gigi into the ceiling in a harsh blow. N does not look surprised, so he might have known what was going to happen. When White cries out a protest, saying that Gigi has never battled, N gives her an expressionless look and says it is not that Gigi has never battled, but that she has never been made to battle. White shouts that doesn't battle go against Team Plasma's tenants, because it forces Pokémon to fight each other and get hurt?
N becomes foreboding and very angry, telling White that if she thinks Pokémon don't want to battle, then she is ignoring their voices. He tells her that a Pokémon Musical isn't a sin, but not listening to your Pokémon is. At that moment, the tearful Gigi retaliates against Sevine's attack, using Ember to deal serious damage. N warmly praises Gigi, who looks up to him in hopeful adoration as he tells her he sees power enough in her to defeat even the Champion.Panicking, White throws open the door of the Ferris wheel, calling to Gigi that they are close enough to the ground to jump. White jumps out of the Ferris wheel, reaching up to catch Bubu—but Bubu jumps into N's lap, the two of them watching as White plummets to the ground.
Alone in the Ferris wheel with Gigi in his arms, N wonders aloud how many Pokémon there are. He will listen to all of their voices. And that is why he will surpass the Champion. He will become invincible and free all Pokémon, and then he will know that he is right.
N has Servine follow White out of the gondola.
N later awakens Zekrom from the Dark Stone and convinces Zekrom to join him.N goes on to defeat the Elite Four without Zekrom's help; he is in the midst of battling Alder when Black and Reshiram interrupt. However, Black has not fully bonded with Reshiram, and it retreats back into the Light Stone. Zorua and Gigi finish off Alder's Pokémon. White confronts N, making him happy when White tells N that she wants Gigi to choose between N and herself. He feels that she is closer to understanding Team Plasma's ideals. As N leaves, Cedric Juniper arrives, and the three of them engage N in battle.
Black, White, and Cedric Juniper defeat Zorua and Gigi. N and Juniper begin to argue about the practice of giving away starter Pokémon, revealing that N had "liberated" a trio of starters a year earlier; Snivy had stayed with N, Oshawott had stayed with Juniper, and the Tepig had vanished. N uses his abilities to hold off Black's Pokémon, and then convinces Black's Munna, Musha to join him. As N and Musha leave, N tells Black that Zekrom wants to fight Black and Reshiram.
N is seen almost all the time in the chapters with a completely emotionless expression on him. The only exception is when he is crying, moved to tears by his perceived suffering of Pokémon. When faced with pokéballs and the Pokédex, and again when telling White she didn't listen to her Pokémon, N grew angry in a very intense, inward-oriented manner, especially when compared to Black's loud, out-of-control reactions.
N has a strong predilection towards giving impromptu speeches.
He is also shown to be very caring about Pokemon and was enraged by how the Pokemon are captured with Poke balls saying that when they are in the Poke balls, their "voice" cannot be heard.
Unlike the games, N is harsh about the topic of pokemon liberation and is more extreme about his beliefs.
N has been seen with the following Pokémon:
Darmanitan has been with N since childhood. Darmanitan faces Zekrom with N, and later battles Alder.
A year before the BW Arc, N "liberates" a set of starters from Cedric Juniper. Snivy stays with him and at some point evolves into Servine. N has Servine join White after the Ferris wheel for unknown reasons.
Tympole faces Black and later Zekrom with N.
Zorua spied on Cedric Juniper to help N "liberate" his starter trio. Zorua later pranks Black's Tepig in Castelia, and then Black himself on the Driftveil Drawbridge. Zorua faces Zekrom with N, and then faces Alder, defeating Alder's last Pokémon. Zorua and Gigi team up against White, Black, and Cedric Juniper, but the duo loses.
N has acknowledged Ghetsis as his father. It is on his request that N began his quest to liberate Pokemon by becoming the hero who controls Zekrom and defeat the champion.
Black thinks that N is a good guy, even if they are enemies. However, Black's opinion about N seems to deteriorate to the point where he considers N a main enemy.
White very much sees N as the enemy. However, N feels that White understands his ideology about Pokemon better than Black does, especially when she chooses not to ask him to return Gigi and instead let her choose for herself.
Anthea and Concordia are much like N's caretakers. In the games, Anthea and Concordia will tell you more about N and Ghetsis.
- His necklace is a communication device that Team Plasma can contact him with
- N's real name is Natural Harmonia Gropius.
- The object dangling from the chain on N's pants resembles a Menger Sponge.
- N is the only villainous team leader that doesn't use Pokemon for evil purposes.
- Some people still debate whether the true leader is Ghetsis or N.
