N is a little silly, innocent goober. He has the personality of a golden retriever. He is incredibly submissive.

N has features of a typical male Disassembly Drone, with flared, boot-like legs instead of his female counterparts' cone-shaped legs. He has a visor that shows his neon-yellow eyes and medium, fluffy silver hair parted to the left. Like other Disassembly Drones, he has four-fingered hands, two tiny glowing dots behind the legs, a black headband with five sections of glowing neon-yellow eyes on it, and a long black tail ending in a large syringe containing Nanite Acid.

He wears a short-sleeved black winter coat with a golden fur collar and a black belt, along with a black pilot hat with a white skull insignia. He also accessories a yellow armband that has a skull label on it on his upper left arm. As shown from a few shots, he also has small fangs. The bottom of his feet and his wrists end in yellow and black hazard stripes. His pajamas are a pink short sleeved pyjama shirt with a golden retriever image on it and the word "Bupper", and matching pink pants with a pattern consisting of bones and digs sleeping on clouds throughout it.

When he is hunting, his mouth reveals several jagged teeth while his eyes become an "X" shape. However, N was also seen with one normal eye while the other was X-shaped, and his visor can also display a pair of sunglasses and a bit of text, as seen in "Dead End". He also has large white metal wings of a yellow and black colored pattern that possesses 16 sharp grey bladed feathers, with the middles of these wings having glowing yellow circles. He can also replace his hands and switched them out for weapons and things that can aid him in his tasks, one of which are three-sharp claws that allow him to tear through any drone and his victims.

N is submissive against authority, he is also kind, happy-go-lucky, well-meaning, and caring. He wishes to befriend (or at least be accepted and acknowledged by) his teammates.

Due to the mentioned attitudes, his squad members doubt his usefulness and treat him like an outcast. Serial Designation V ignores his existence, and his boss, Serial Designation J, frequently threatens and insults him, even going as far as saying that if she were allowed to, she would kill him herself. Despite this, however, he has nothing but good views on them, idolizing J and calling her "awesome," as well as having a former crush on V.

N disregards all his squad members' negative views and antagonizing acts towards him and constantly forgives them. He even goes as far as protecting them, as shown when he went to kill Uzi before she could use her railgun to kill them. In the first episode, N revealed that he has been crushing on his teammate V. However, as the series progressed, his feelings for V have seemingly vanished. Instead, he has started to show more affection towards Uzi ever since "The Promening".

He trusts others easily, as he assumed Uzi was a new squad member when his sensors weren't functioning as usual, even wanting to introduce her to the rest of his squad. He also did not pick up on the signs that Uzi was lying (stuttering, asking what "we" meant, etc.) and even thought that Uzi was just trying something "new" when she stuck her hand in his mouth to neutralize the Nanite Acid, rather than picking up immediately on the fact that she couldn't do it herself. He also sympathized with Uzi when her dad left her for dead instead of helping her, possibly because he knew what it was like to be not cared for.

Despite all claims to the contrary, N is a capable Disassembly Drone, having skillfully used his weaponry to a reasonable extent, such as having the accuracy to stab through a door control panel to force open the doors to Outpost 3. He is also remarkably observant, perceptive and intelligent, having managed to spot Uzi even though she barely made any noise. He also acknowledged the threat posed by Uzi's railgun to his teammates.

N is not hesitant to lick or use his tongue on things. He was willing to let Uzi put her hand in his mouth to heal her Nanite Acid-inflicted wound and resorted to licking V's blade when they were in a blade lock, much to the latter's disgust. Both times he uses the word "repressed."

He can set boundaries for himself, even confronting V without hesitation.

Deep down, N was scared and just wanted to have Uzi by his side, as after they met, things were less scary for him. N has also been shown to suppress his trauma frequently. He keeps his overly optimistic personality intact to help his friends. Even when being tortured by Beau, he's still friendly and encouraging towards them.

Unfortunately, his kindness can be taken advantage of, as shown when V deceives N with false promises to only kill when necessary so he can unchain her, and when he battles with a Solver-possessed Uzi, it brings his guard down when looking at Uzi. This also leads to him frequently holding back. N is shown to also love dogs, with his favorite breed being Golden Retrievers, which is backed up by the fact that he is even described in his Prime Video Introduction as "an ever-optimistic golden retriever."
