A/N I created my own RotG OC some time after seeing the movie (which I really enjoyed) I managed to create a plot in the past few months, and am now writing it.

I had to alter Haley a bit, and research Halloween a bit, to try and get her good. Hopefully, I don't disappoint. I only own Haley in this story; the rest belongs to Dreamworks.

Prologue
A New Spirit is Born

16th Century Spain

A small black cat trotted down the empty streets of Spain, sniffing around for any food she could find. She was a stray cat, without a home, and it was often hard to find a small snack to briefly satisfy her hunger, let alone be a complete meal. But luckily, some kind child would almost always give her something to eat, so she would rely on the children if times were harsh.

As she stood up and placed her paws against a trash bin, a door opened. A small dog came out and immediately began barking. The cat jumped back with a screech and ran away as fast as she could; the dog's barks and its owner's shouts soon disappeared behind her.

That was one thing the cat avoided: dogs. Life on the street taught her that no dog could be trusted; they chased and sometimes killed cats, and stole any food they could get their muzzles on. So any dog, big or small, was avoided at all costs.

Soon, she was far enough away that she didn't hear the dog anymore. When she slowed to a stop, she was near a large body of water. As with most cats, this one disliked water. She seldom set paw in the water unless she absolutely had to.

She jumped in surprise as she heard cruel laughter. Behind her were several human boys; the lead one was the tallest, and was the one laughing. And they were all headed right for her.

"Cuidado," One boy said. "Un gato negro que cruza su trayectoria es mala suerte."

The cat pinned her ears back; she didn't know what this boy was saying, but it didn't sound good.

"¿Sí? Tal vez deberíamos disponer de la mala suerte." The lead boy answered. This made the other boys chuckle. They began to approach the cat, who was becoming very nervous. Before she could get away, the lead boy grabbed her by the scruff.

The cat screeched and hissed and scratched. Cursing loudly, the boy threw her into the lake as far as he could. When she scrambled to the surface, the boys all began throwing rocks at her. Some of them missed, but a few of them battered the poor cat, making it hard for her to stay above water or swim to shore. When one large rock hit her on the head, she sunk down into the cold water, and never surfaced.

When her eyes opened, to her surprise, she was on dry land, lying on her back. There was no one and nothing in sight; only the full moon shining down on her.

When the cat rolled onto her feet, she realized she was taller than she used to be. Sitting and looking down at herself, she realized in shock that she had grown until much larger, and her front paws had opposable thumbs. She was also able to stand on her hind feet, standing at almost five feet in height. When she looked in the reflection of the pond, she almost didn't recognize herself. She was still a cat, but looked like a cat crossed with a human.

Her ears pricked back at a noise. She saw the boys who had thrown her into the river, laughing and joking among themselves. Her light-green eyes narrowed, and her lips pulled back in a snarl. "You did this to me!" She bounded towards the boys; once she was close enough, she pounced. To her shock, she fell right through them as if they were mirages. She tumbled to the dirt, landing on her stomach.

She stood up, brushed off her fur, and looked around, feeling very confused. She walked into town, often tripping over her new legs as though she was a kit learning to walk; only this time, she was learning to walk on two legs instead of four.

When she found some humans, she asked, "Um, excuse me, do you see me?" She waved a paw in front of a man's face, but he didn't notice her. She tapped a woman on the shoulder, but her paw went through the woman. The cat gasped, staring at her paw. It wasn't the humans that were untouchable; it was her herself.

"…Haley…"

The cat looked around for the voice. "Hello?" She called. "Are you talking to me? …Who are you? Where are you?" The voice sounded as though it were in her head.

"…Haley…"

The cat looked up at the moon curiously. "…Are you the one talking to me?" She asked softly, wondering if she was going crazy.

"…Your name is Haley O' Eve…You are the Spirit of All Hallows Eve."

"All Hallows Eve? What do you mean? Did you do this to me? What did you do to me? Why? Who are you?"

…Nothing. The moon was silent. All the cat knew was that her new name was Haley O' Eve, and she was the Spirit of All Hallows Eve; in the future, she would be the Spirit of Halloween.

A/N I know Haley's death was like Jack Frosts, concerning water, but her death is different; she didn't try to save anyone, and she didn't fall through ice.

I just want to say I would NEVER hurt a cat on purpose; I especially wouldn't throw one into the water. I just wanted to create an interesting death for Haley.

Ah, the mysterious Man in the Moon.

Fun Fact: Halloween was indeed known as All Hallows Eve in the past. It kinda sounds like Halloween, so I can see how it evolved into that name today.
