A/N: And here is the first chapter of my Halloween oneshot story! I hope all of you like it.

No, I do not own Danny Phantom though I certainly wish that I did. Please read and review! Now have a spook-tacular time reading this first installment!

Metamorphose

"What are you going as?" Sam asked Danny as she placed a fake wart on her nose.

Danny shrugged. "I don't know. I'm probably not going trick or treating this year anyway."

Sam turned and gave Danny a questioning look. He looked up to her from his place on his bed. "Why not?"

"Well… Everyone knows who I am now. I don't want them to… I don't know, give me extra candy or anything. Besides, it's Halloween and the ghosts are going to be going crazy tonight. Someone has to watch over everyone." Danny smiled sadly. His eyes flashed green with emotion before returning to their usual blue.

"Danny…" Sam started as she applied the rest of the make up. "You really need to give yourself a break. Your parents and Valerie can handle the ghosts tonight. You know how Valerie hates Halloween."

Danny chuckled. That was certainly true, that Valerie hated Halloween that is. Ever since last year's haunted candy incident, the red huntress had come to despise the season. Ever since then she had hunted ghosts with a new fervor, if that was possible.

"Still, it's my duty to protect the town…" Danny started to argue.

Sam smirked and sat down on Danny's lap. One hand glided up his back and gently massaged while she bent close to his face and kissed him.

"… unless my girlfriend says so," Danny whispered in a hypnotized sort of way.

"Yep, thought you'd see things my way," Sam answered, still smirking. She got up off him and guided him out of the room.

Danny began snapping out of it. He shook his head as if to clear it and pouted. "Fine, I'll come with you, but I'm staying in ghost mode and if I see a ghost I'm going after it."

The goth witch shrugged. "Have it your way."

She grabbed her pillow case and walked out the door. Danny shifted into his ghost mode and followed. Outside demons, angels, cats, pumpkins, sheet ghosts, witches, warlocks, a plumber, babies, faceless ghouls, grim reapers, werewolves, an apple, bunnies, dead princesses and princes, and these creatures' respective parents roamed through the streets knocking on doors in hopes of receiving candy. Danny and Sam scanned the crowd for a moment before joining the swaying, running, jostling, and screaming mob. They ducked and dodged waving arms and kicking legs to get to their first house. Sam ran up the walkway. She rang the doorbell. After a moment the door opened to reveal a fairy girl holding a bucket of candy.

"Trick or treat!" Sam cackled and held her pillow case open.

Danny watched from the sidewalk as the fairy dropped a hand full of candy into Sam's pillow case. Sam thanked the fairy before running back to join her ghostly boy friend on the sidewalk.

"Whatcha get?" Danny asked.

Sam looked into her bag. "Uh… a lollipop, a candy bar, and… a marshmallow?"

Sam pulled out the strange treat before eating it. "Well that's weird," commented Danny.

Sam nodded. "Yeah, but it's still candy."

They visited a few more houses, Danny staying on the sidewalk while Sam dashed up the house to ring the doorbell and receive a few treats. Sam's bag quickly filled. Strangely enough, Danny didn't have to fight any ghosts.

Danny gasped as a blue wisp of breath escaped his mouth.

Never mind. Looks like the ghosts were active tonight.

"Ghost?" Sam asked with regret.

Danny nodded and took off for the skies. He spiraled upward dramatically until he was hovering just over the roofs. His brilliantly green eyes searched for the source of the disturbance. It took him a minute but he soon found the perpetrator.

"What the… Who in the world is that?" he asked no one in particular for it was a new ghost.

The specter seemed to be about Danny's size with an eerie billowing black cloak and a red mask over his face. The mask covered the full of his face for all but his eyes and mouth. The eyes were yellow and glowing with malice as the ghost floated above a tree.

Danny's eyes narrowed as he sped over to his opponent.

"So, who'd you steal the costume from?" he bantered when he was within feet of the new ghost.

The black hooded head turned to glare at Danny. The ghost didn't answer with words, but with a single crimson blast that came within millimeters of Danny's head.

"Not the friendly sort, huh? Fine by me!" Danny shouted as he flung a blast of his own. The green blast nearly hit the ghost as hit sprung into the air.

A crowd of people gathered below to watch the aerial ghost fight. They ooh'ed and ahh'ed at the spectacle, finding the fight just as exhilarating as its participants.

Danny raced across the sky, dodging blasts, returning fire, and shielding civilians from stray blasts. After about a half hour of this he started to tire and that's when the trouble began.

It started with a change in the sky. The black night sky glowed with a strange purple light. Then stars seemingly began to fall. The "stars" hit the masked and costumed children. For a brief second their costumes disappeared, revealing stunned faces. Then the moment passed and monsters were left in the places of trick-or-treaters. Where once stood a costumed kid now stood (or floated) a monster ready to attack their parents and fellow villains.

Danny stared down in horror at the scene beneath him. "What did you do?!"

No answer.

In frustration Danny flew at his enemy, tackling the bizarre ghost. They hurtled to the ground, slamming into the concrete. Danny grabbed the ghost by the front of his cloak. "TELL ME WHAT YOU DID!"

One skeletal hand reached up from the folds of the sleeves and touched Danny's forehead. Danny froze.

"Get away from him!" a voice shrieked. A silvery bullet of light zipped towards them and smacked into the opposing ghost. The ghost immediately melted into a puddle of goop. "He's mine!"

Danny blinked and turned to the origin of the blast. What he saw shocked him. Where Sam should have been standing, for he recognized the voice, stood an ugly hag of a witch. Her tattered violet dress hung over her now sickly bony body. Her silver pendent glowed with a magical light. Messed up raven hair stuck out at odd angles and her eyes held the gleam of insanity. The ghost may have been gone but the nightmare was far from over.

"Hello my darling," cooed Danny's possessed girlfriend. "I believe you and I have business to attend to."

"Sam? Are you okay?" Danny asked with concern. Everyone else around them was clawing at each other, warring for dominance. What if Sam was changed too?

"Of course my dear," Sam the witch replied. "Now come!" She waved her arm in invitation for him to come closer.

Danny looked warily at her but obeyed. "So, how can we end this?"

"Simple," Sam replied. She waved her hand in Danny's face. Her pendent glowed and the air around them crackled. Red light seeped into Danny's eyes. "We don't."

"Yes, my mistress," Danny agreed.

The spell was cast.
