(Story)

You were walking across the street when you see a kitten

(And that's pretty much it)

Nightmare: Black cat, one eye with the left one scratched and closed

Killer: White cat with grey stripes on his back and one on his head that resembles a knife, he also has a red birthmark that looks like a target on his chest, his underside is white

Horror: light Grey-ish cat with one is his ears missing and 1/4th of his face where his left eye is colored black, his belly is white

Error: Black cat with blue streaks running down his face, also has yellow stripes on his back and his tail fades from black to red

Dust: grey cat, black stripes on his back, end of his tail is black and his stomach is white

For their eyes, they just have the same eyes as they do when they're a skeleton, they can change from neko to cat as they desire
