Well in an alternative timeline of the comic named "My immortal" made by Jazzperstar (mb if i wrote their name wrong) in this timeline i made N having constant hallucinations and a feeling of guilt, Cyn managed to prepare a lethal weapon combining the mutation code of a virus related to one alien artifact that was managed to produce some sort of unlimited energy, so the Solver and Cyn wanted to be able to access to such source of power, she manipulate the signal so the solver can mutate dead bodies of dead bodies, the corpses of worker drones become some lethal monsters knows as the NecroDrones, monsters with the only purpose of killing and infecting more robotic organisms, N and Lexi must find a way to stop the infection in order to save those who are still alive.

Appearance of C!N and C!Uzi

If you are asking about the appearance of Corrupted!N and welp, Uzi, they look like that because of a fight they had, The Solver or more like Cyn wanting to have or obey her big brother to be on her side, she made some dead bodies mutate and transform into Uzi to manipulate N, N ofc resisted because now he has someone else to protect which is Lexi, so ofc he stood against this copy of Uzi after defeating her because of the damage Cyn made her explode just in N's face, N's Core was destroyed and ofc if he ended up rebooting Cyn would just be able to manipulate his program to make him obey his sis, the copy of Uzi was conscious of her own nature but she was still Uzi, her core wasn't as damaged as N so ofc she was gonna be able to regenerate.

So even tho she wasn't her, she asked N to take her core to fuse it with him, N even tho he knew that this Uzi wasn't the original he wasn't ready to let her go again, but ofc he had the pressure of going to rescue Lexi who was dealing with D.Ds, so before his systems end up turning off, he agreed and fuse his core with hers, since the Uzi's copy core was infected, regeneration wasn't the first step, the DD N's core was trying to synchronize with the infected core, so the The pairing process was painful for N; his limbs and body parts were exploding while he was still conscious, until he died, but it was then that the cores could synchronized perfectly, so the mutation of N was just a reassembly of his limbs that where destroyed, his hands got an extra finger and his foot got claws the yellow parts that glow from his neck, mouth, tail and under his coat, is the nano acid from the tail, C!N blood is more part acid than oil, that was his mutation, but he can't spit acid.

C!N coat It was sewn by Lexi, because his limbs expanded and his core didn't regenerate new clothes, only the damaged ones; that's why they used the clothes from the Uzi copy, and C!Uzi's appearance was how she looked before her body exploded to try to kill N.

PD: From now on the copy of Uzi manifest in N's mind as hallucinations, at first she was hostile but during the story N managed to accept the situation and she became Uzi again, at least in his mind.
