A/N: I swore I wouldn't do this, but this idea has nagged at me all day and won't leave me alone. Another Danny Phantom fanfic (I swear somehow my DP fanfics never look right) but my Gravity Falls obsession has just now kicked in. I love the show already.

Part one: Ghosts are real? Since when are they real?

My name is Danny. Danny Fenton. Several years ago, I would have dismissed my parents' claims about ghosts as absurd...until I was turned into a halfa, half-human, half-ghost. Unbelievable, am I right?

Well, I've seen impossible stuff that'll blow your mind. Like running from a crazy knight with a sword hell-bent on destroying the world, saving the future from your evil alter ego, stuff like that. Things that most ordinary kids don't need to go through.

Now I'm a superhero saving the world.

Although, I forgot to mention a few complicated parts to this whole I'm-a-superhero-business. First off, my whole town hates me and they condemn my existence. Then there's the small matter of my parents wanting to dissect me alive for hunting purposes. Yeah, you can see why I'm kinda terrified of them. Though they already humiliate me in real life, why o should they attack me in my afterlife?

Well, if my life wasn't already complicated, it was about to get ten thousand times more complicated, thanks to lovely old mom and dad.

It was just an ordinary Monday morning; I was getting prepared for school when I heard the shout of my father (he didn't have to be so loud, I could already hear him, ghost hearing improved my senses and all) but it wasn't like he knew that. Thank goodness, I'd heard them talking about wanting to dissect the ghost kid enough. They didn't need to know it was me.

"KIDS, COME DOWNSTAIRS, YOUR MOTHER AND I HAVE SOMETHING TO DISCUSS WITH YOU."

Immediately, I obeyed, but Jazz and I traded looks of disbelief while we headed downstairs, wondering what they could be on about, probably some new invention of theirs or something.

"Are they planning some crazy ghost gadget again, Danny?" Jazz asked in exasperation, by now tired of our parents' crazy attitudes.

I sighed, shaking my head. "Whatever it is, we'll find out, won't we?"

Mom and Dad were already waiting for us when we got downstairs, packing things into a bag. I stared at them in disbelief. What could all this be about?

"...Kids, your mother and I have decided that we all need a break from Amity Park. We're going to head out west for a vacation for a few weeks. It'll be a nice place!" Jack cried.

Instantly, we were wary.

I made no moves to stand up.

"Does it involve ghosts?" I asked, dreading the answer.

"As a matter of fact, yes it does!" Dad cried, to the surprise of no one. "Now who wants to listen to me talk about ghosts?"

Only Mom looked vaguely enthused. I was slouching back, looking absolutely bored. I fought ghosts enough times and I was a halfa. I got sick of the topic of ghosts. Jazz frowned.

"Sorry, Dad, not today," Jazz mumbled.

"It's a very unique town. A small town, in fact, in the middle of the woods."

"That sounds like a great idea, Dad." Jazz snarked.

"Oh, come on, the ghost stories for this place sounded amazing. Plus, it'll be nice to get away from the house for a while!" Mom chirped. "Don't you think so, Danny?"

I nodded my head, stifling a yawn. Screw that stupid ghost last night, keeping me awake.

"We're going to Gravity Falls, Oregon! It's a nice little town." Dad said.

"Hooray." I mumbled. "When do we leave?"

"Now!" Jack said.

Groaning, Jazz and I went to get our things while Mom assured us things would be delightfully normal there. Little did I know my life would become ten thousand times weirder. If I'd thought my propensity for attracting trouble was bad, the two people I was about to meet had it even worse. If that's even possible.

The road to Gravity Falls took us about two days, of which we spent camped out in hotels, mostly because Mom refused to let us sleep in the hot Fenton RV. Not that it would have bothered me that much.

As the tall trees loomed around us, the first thought I had of the woods was that something evil was lurking within them, waiting to swallow us whole. My ghost sense went off at that second. Only Jazz noticed.

"Do you think...?" She began.

"Yeah," I said, "There are definitely ghosts in this town."

"We're going to stay in one of the houses here. Danny, you're going to meet an old friend of ours, Stan Pines, and his mystery shack. We go way back! We were friends in high school!"

Dad went into one of his long stories that I paid absolutely no attention to.

While Mom and Dad set up, I decided to go investigate the source of the ghosts.

I transformed and flew into the general town square, turning invisible.

"Hey, Mabel, did you feel that? It felt like something cold just touched me..." A brown-haired boy near me complained.

I froze, and remained still.

"...I think you imagined it, silly." The dark-haired girl beside him said.

I found myself in front of an old cafe.

Inside, everything was abandoned and rundown, but as I floated in, suddenly the lights blazed on and two figures appeared before me, two elderly people.

They didn't look very happy.

"Teenagers! Above all that, a ghost teen! Are you going to wreck our store, too?" The man boomed.

But his wife was looking at me in a funny way. It was as though she knew me.

"Uh, sir, I'm not looking for trouble. You see, my name is Danny Phantom, and I'm new here."

"Danny Phantom?" He said. "I know of you. You're that boy who defeated Pariah Dark. Every ghost as heard of you."

"I knew you looked familiar!" His wife said. "You're always welcome here, Danny Phantom."

"I really must be going," I said, as I knew I had to rejoin my family.

As I flew, I thought over those odd people. "They really were nice old ghosts, but weird."

I decided to fly to this place called the Mystery Shack. In all retrospect, going visible might not have been the best idea.

The same boy from before was sitting on top of the building called the Mystery Shack, reading an odd book. He wore a blue and white hat on his head.

I flew up there, forgetting that I was in my ghost form, and spoke.

"Hello there, is this the Mystery Shack?"

The boy didn't even lift his head from his book.

"Yes, it is, Grunkle Stan's downstairs...wait, how did you get up here?"

His mouth fell open as he took me in, from head to toe.

"You're floating!" He cried.

"Yeah, so?" I said.

"Your hair is white and you're glowing! You're a g-g-"

"Yes, I'm a ghost. Anything else you care to state that's obvious?"

The boy dropped his book, which I flew down and caught for him, which just caused him to scream even louder.

He snatched his book from my arms. "MABEL, COME SEE THIS GHOST!"

Oh, crap.

Instantly, I turned invisible and flew away, changing back into my normal self.

"The ghost was here a second ago, Mabel," The boy said.

"Oh, Dipper, you imagined it." Mabel said. "The new people don't need to be scared by your tall tales."

"I was not imagining him, Mabel! He was wearing a black and white oufit, had no legs, was glowing, and had white hair-"

His breath caught in his throat as he stared at me.

"Who are you?" He said, warily.

"Hi, I'm Danny Fenton, a new kid in town whose parents dragged him here against his will."

The brown-haired girl shook my hand fiercely.

"You're so cute! I'm Mabel and this is Dipper. Can I call you Dan?"

"No one calls me Dan," I growled.

She flinched. "Okay, then, Danny will do."

"That's better," I mumbled.

Dipper came up to me. "You're a ghost, aren't you?"

Mabel looked at him and burst out laughing.

"Dip, you're really being delusional this time."

"I am not delusional!" Dipper cried.

I really hoped he wouldn't figure me out.

Great, and this is only day one of my vacation. What else could go wrong?
