Welcome to my NCIS/ Danny Phantom crossover! This is a story idea I've been thinking about for days now and I thought it was a good time to begin. Hope you love it! Anyway, here are two things you need to know:

1. This is shortly after Reality Trip in the Danny Phantom timeline.

2. This is randomly in between Seasons 6-9 in the NCIS timeline.

Prologue

Danny Fenton, Sam Manson and Tucker Foley; three best friends on summer vacation. With nothing to do for the summer and a need to escape Amity Park, especially after their recent encounter with Freakshow, they decided that their summer could best be spent in the nation's capital, Washington DC.

A few overshadowings here and there, and Danny, Sam and Tucker found themselves clinging to their seats for dear life as Danny's dad, Jack Fenton, sped across the American landscape. Little did the three teens know, a new adventure would suck them in and twist their lives in new ways. And it would begin at their destination…

Chapter 1: Hunter, Hunted

"Okay, I've got to admit," Danny said, "We picked a pretty sweet place to vacation."

"Too many places to visit." Tucker said, clutching his PDA and going through a list of tourist sites. "And so little time. Good thing we're here for a week, huh?"

"You said it, Tuck." Danny said. He looked at his friends. "This is great: no more school, no more Freakshow and no more-." The three were suddenly blinded by a flash of green light. Looking down a nearby alleyway, the teens saw a hovering green shape that could only be a portal. "Ghosts?"

"I'm tracking a shape, moving quickly." Tucker said. "It's leaving the area."

"Maybe that's a good thing." Sam said, shrugging. She began to turn away.

"Wait!" Danny said. He held out a hand and, in the silence that followed, the teens could hear voices; whoever they belonged to sounded angry. A shot was heard, slashing the silence like a knife.

"I'm going Ghost!" Danny said. Two white rings appeared around his waist and transformed him. His once black hair and blue eyes were now white and green respectively. His legs turned into a tail and he quickly flew around the corner, in the direction of the voices.

"Uh, guys?" Danny called. Sam and Tucker rounded the corner and found themselves in a darker bend of the alleyway. Danny charged up a ball of ecto-energy and held it up as a light source.

Blood.

That was the first thing the kids saw; shiny, crimson, blood. A man was in the center of it, a hole in the front of his head. The man's eyes were open but unseeing.

"Creepy." Sam whispered.

In shock, Danny floated back down to the ground and transformed back to his human self, his mouth agape. "Guys?"

Tucker and Sam turned to look at him, both of them had serious looks on their faces.

"I think we've stumbled onto a crime scene."

"Morning DiNozzo, McGee, Ziva."

"Morning boss."

Leroy Jethro Gibbs, special agent of NCIS, walked through a doorway and into the NCIS office bullpen. He had a grim expression. "I just got a call."

"A murder?" ex-Mossad agent, Ziva David, asked.

Gibbs nodded and kept walking, headed for a nearby elevator. "Not far from here." Anthony DiNozzo picked up his camera and both agents stood up and followed their boss. Tony turned back to the last agent in the room, Timothy McGee, who was by his desk.

"Just…keep doing whatever, McGeek."

McGee, hearing his nickname, looked up from his laptop just as the elevator doors closed. He looked around, noticed he was alone, shrugged, and then went back to clacking away at his keyboard.

The drive took 15 minutes. They were outside the alleyway, alone, although they could all hear police cars in the distance.

"It's funny that we get the call after the police and arrive before them." Tony said, getting out of the sleek black car. "Do you think they were all on a lunch break and just had to finish eating?"

He looked back at Ziva, who smiled. Gibbs, however, was not amused. "Let's see what's going on."

They headed into the alleyway and turned a corner…only to find themselves looking at three kids. They all had their backs to them but they seemed to be teenagers.

"What are you three doing here?" Gibbs asked.

The three kids jumped in surprise and spun around. Two boys and a girl. The girl was wearing only black and purple. One boy was wearing green shorts and a yellow shirt. The other boy was wearing blue jeans and a white shirt and black hair.

"Aw, Gibbs, they're only kids." Tony said.

Tucker, who had turned around first, noticed Ziva standing behind the two men. He smiled and held out his hand to Ziva. "Hey, I'm Tucker Foley. That's TF, as in Too Fine!"

Sam snorted. "Tucker, I think you could be arrested for hitting on a cop."

"Well, we're not exactly cops," Tony said, trying to hold back laughter. He held up his badge. "NCIS."

Tucker pressed a few buttons on his PDA. "NCIS? As in Naval Criminal Investigative Service. Security, counter-intel and counter-terrorism. Been around since 1992"

Tony looked at Tucker strangely, "How'd you get that so quickly?" he turned to Ziva. "He's like a kid version of McGeek."

"Don't mind Tucker." The black haired boy said, rolling his eyes. "He's a techno-geek."

Tony pretended to look stunned. "He is a kid version of McGeek."

Gibbs also seemed impressed, but his question hadn't been answered yet. "What are you three doing here? Who are you?"

Danny, Tucker and Sam, exchanged glances.

"We… we were walking down the street and we heard voices." Danny said. " We were curious and followed the voices until we heard a shot and found ourselves here."

"Did you see who fired the shot?" Ziva asked.

All three kids shook their heads. Danny gestured at Tucker. "To answer your second question, you've already 'met' Tucker." He pointed at himself and Sam. "I'm Danny Fenton and this is Sam."

"As in Samantha?" Tony asked. Danny laughed at this.

"Call her that today, and you'll wake up in a ditch tomorrow."

Tony stole a glance at Ziva, who was grinning at him. He knew exactly what she was thinking.

"We have more questions for you but we can take you back to our headquarters for those." Gibbs said. "C'mon."

"Wait." Danny said. "Did you guys see anything when you came in here.

"Like what?" Tony asked.

"Like a…green thing…floating in the air." Danny rubbed the back of his neck. Gibbs could tell that he was embarrassed.

"Why?" he asked.

Danny looked down. "No reason."

Gibbs, Ziva and Tony looked at each other. Each made a mental note to ask about this later.

Danny is hiding something. Gibbs thought, And I'm going to get time to find out what.

How's that for a first chapter. I noticed that there weren't many Danny Phantom/NCIS crossovers so I thought of one! Please review if you like it. I need to know if I should continue it.

Thanx
