A/N: This is my first ever Danny Phantom fanfic, and also the first fanfic I've written in over two years. I'm also not writing in my native language, and I'm writing about characters in a country I've never been to. If characterization is a bit off, or the storytelling seems a bit dull, keep that in mind. Also, tell me so that I can improve.

Also, before we start, I'd like to clarify some things about this fic. First off, unlike 99% of Danny Phantom fanfics, this fic DOES NOT ignore Phantom Planet - it takes place an undetermined but not too long amount of time after it. Second, because of this, Danny doesn't exactly have a secret identity anymore - everyone knows who he is. Third, while they don't bully him anymore because they've just realized how dangerous that actually is, the 'popular kids' in school still don't accept Danny and co. as among them. They've been boosted in the social hierarchy from 'bullying victims' to 'neither popular nor unpopular'.

Oh, and also, while this story contains heavy references to Norse mythology - heck, the main villain is LOKI, and a lot of other characters from those myths also make an appearance, this is in no way a crossover with Marvel's version of Thor or any other adaptation of the myths, instead it's just me using the knowledge I have of the original myths and trying to fit them into the DP universe.

Prologue

General POV

"Oh Allfather, it is a disaster!"

The Allfather, an old man with only one eye, looked up. The voice had come from a young soldier who had burst into his throne room unannounced. He hadn't even bothered to close the door behind him, and the Allfather could glimpse a battle taking place right outside it.

"What has happened?" he asked.

"It's Loki. He took his children and left. Even Sleipner is gone!" said the soldier.

The Allfather sighed and leaned his head on his left hand.

"Go get my son."

Chapter 1

General POV

The sun was shining in Amity Park. There was nothing unusual about that; the sun often shines all over the world. There's probably no place on Earth where the sun doesn't shine at least occasionally.

What was unusual, however, was the flying shoe boxes blocking it from view. They were zapping around above the streets at high speeds and occasionally hitting the fleeing civilians. In the midst of them floated a blue-tinted man in a construction worker's outfit.

"Beware!" shouted the man while waving his arms, "I am the Box Ghost, and with these Shoe Boxes I shall take over the world!"

Meanwhile, a trio of teenagers were standing on the sidewalk and looking at him.

"This guy again?" asked one of them, a girl with hair as dark as her clothes and thick eyeliner.

"You'd think he'd have learned by now," answered another, this one a dark-skinned boy with glasses and a red beret. In his left hand he was clutching an advanced electronic device.

The third, a dark-haired boy with bright blue eyes, sighed. "I'll take care of him," he said and looked around for a hiding place, before remembering he didn't need one anymore. Ever since he'd saved the world from that huge green asteroid, everyone already knew who he was. "I'm going ghost!"

A circle of light formed around the boy's waist, and split like a curtain to reveal his alternate self. Dark hair turned white, blue eyes turned green and his relatively normal clothes exchanged for a black and white jumpsuit.

As soon as his transformation was complete, the surrounding civilians started cheering. "It's the Phantom!" they said, "He'll save us!"

Danny Phantom, for that was the ghost-boy's name, smirked. "Hey ugly!" he called as he leapt off the ground. The blue man – The Box Ghost – turned around in surprise.

"Beware!" shouted the ghost, once again waving his arms. The shoe boxes, which had previously flown around randomly, organized themselves and flew toward Danny.

The attack was meaningless, as the boy simply turned himself intangible and let the boxes fly straight through him. "That all you got?" he asked, before firing a ray of green energy from his palm straight into the ghost.

The Box Ghost cried out in alarm. "I surrender! I surrender!" he yelled and continued wailing his arms.

Down on the ground, the dark-haired girl had produced what appeared to be a technologically advanced thermos, and pointed it at the ghost. "See you later!" she shouted, and pressed a button on the thermos. A silver vortex surrounded the Box Ghost and sucked him into the thermos.

"Good job, Sam" said Danny as he landed. The girl, Sam, merely laughed it off.

"It was just the Box Ghost," she said, "Nothing to phone home about"

"Great job guys!" shouted the boy in glasses, Tucker, whilst running toward them.

Danny was about to repeat what Sam had said to him, when a terrifying roar came from behind the group. He quickly turned around and put himself in front of his friends.

In front of him was a ghost unlike any he'd ever seen before. It was a huge wolf, but unlike the blue or green coloration of most ghostly animals its fur was a dark grey. Its eyes were red as blood, and a thin, almost see-through rope was tied around its neck. From its mouth ran a thick stream of clear drool. The only thing identifying it as a ghost and not some freak of nature was the green glow emanating from its skin.

"What is that?" questioned Sam. "I've never seen anything like it"

"I don't know, but it's not getting past me!" yelled Danny as he once again took to the skies. The wolf growled and barked at him.

Danny fired a ghost ray at the wolf, but it dodged it and leapt onto the ghost boy. Danny yelped in surprise, but quickly recovered by firing a close-range ray straight into the wolf's face. The wolf howled in pain and turned around to run away.

"Not so fast!" yelled Danny and flew after it. He closed his eyes and concentrated, and when he opened him the green glow had been replaced by an icy blue. He fired and equally cold-looking ray at the ground in front of the wolf, and a wall of ice grew out of the ground to surround it. The wolf growled and turned around, only to be hit by another green ray to the face. However, unlike the first hit, this only served to make the wolf angry. It barked loudly and then proceeded to run up the wall of ice, after which it jumped off towards Danny, who quickly dodged.

This, however, meant the wolf was now standing right in front of Sam and Tucker, who stepped back in surprise.

"Danny!" yelled Sam, and the mentioned half-ghost turned around. When he saw what was going on, he quickly flew toward his friends, and reached them just in time to fly them out of harm's way. He then flew back to the wolf and hit it in the face with another close-range ray. The wolf once again howled and tried to run away, but Danny caught the end of the rope hanging from its neck. At once, the wolf stopped struggling and seemed to accept defeat.

"Sam, get it with the thermos!" yelled Danny to his friends.

"I'm on it!" answered Sam and captured the wolf-like ghost.

Once the danger was over, Danny sank to the ground and turned back into his human form. Sam and Tucker ran over to him, and Tucker reached him just in time to catch the boy as he collapsed from exhaustion. When they realized the battle was over, curious citizens started emerging from their hiding places, but Sam and Tucker paid them no mind as they carried their unconscious friend home.

In the distance, a raven could be seen taking flight.

"Fenrir has been defeated, father"

The voice was that of a young female. Her face and body was covered by a black hooded cape, but you could see strands of hair peeking out from beneath the hood – some white, some black.

She was speaking to a very tall man, who was wearing a cloak similar to hers in all but color – while her cloak was plain and black, his was dark green with a golden trim and matching embroidery covering it.

"It seems the people of Midgard are stronger than expected," said the man. His voice was deep, and it reminded the young woman of the rumble of an earthquake. "I want you to look into this. Take this amulet of shapeshifting, and blend in among the humans."

"Yes, father," said the woman and looked up, revealing her face – half that of a beautiful human woman, with dark hair, fair skin and a deep blue eye, and the other half a pale blue, with white hair and a glowing green eye.

A/N: So yeah, there you go. First chapter. Hope you liked it, and stay tuned for more.

Oh, and, one more thing I forgot to mention earlier, the Asgardians/Norse gods/whatever you want to call them have different names for things in the DP universe. I'll keep a list of words here and update it as the story goes along, so you don't get confused.

Asgardian words:
Midgard - The human world
Helheim - The ghostzone
Asgard - The part of the ghostzone where the Asgardians live
Halfling - Halfa (this one is just there because I think halfa is such a stupid-sounding word ugh)
