SD-N

N has features of a typical male Disassembly Drone, with neon yellow eyes and short 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 lights on it, and a long black tail ending in a large syringe, the headband and syringe both containing Nanite Acid. After his head was destroyed by Uzi's railgun, one of his headband lights was colored red, which reverted to yellow after his system rebooted thanks to J slapping him in the head. He wears a black winter coat with a fur collar and a black pilot hat.

When he is hunting, his mouth reveals several jagged teeth while his eyes become an "X" shape. N was also seen with one normal eye while the other was X-shaped. His visor can also display a pair of sunglasses and a bit of text, as seen in Dead End. He also has metal wings with bladed feathers and claws that allow him to tear through any drone. N is kind, naive, timid, socially awkward, 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. V ignores his existence, and J frequently threatens and insults him, even going as far as saying that if she were allowed to kill him, she wouldn't hesitate to do so. In spite of this he has nothing but good views on them, idolizing J and calling her "awesome" and 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 has seemingly vanished. Instead, he has started to show more affection towards Uzi ever since Episode 3.

He trusts others easily, as he assumed Uzi was a new squad member when his systems 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 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.

After the events of Cabin Fever, N has a newfound confidence, and his charming personality makes Uzi's classmates swoon over him. 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 coerces N with false promises to only kill when necessary so he could unchain her, and when he was battling with a Solver-possessed Uzi, it brought his guard down when looking at N as Uzi.
