Prologue

Somewhere in the many green hued abyss of the Ghost Zone, stood a castle-like structure with a clock in the upper most tower. Around the place were floating gears, turning as they measured time. Inside the castle building, housed one of the most ancient and powerful ghost of the Ghost Zone; a blue-hued ghost called Clockwork. His former title, The Master of Time or Time Master. This ghost has been around for a very long time, watching over the timeline of his universe to make sure that nothing goes too astray.

Of course, this means that he is most often bothered by people that seek his help. Most often by these one-eyed creatures called the Observants; that had once hired the Time Ghost to destroy a certain person.

But that is a different story.

No, the Time Master wasn't being bothered by those green one-eyed creatures; instead he was being bothered by an elderly man.

One that was not from his universe.

"So." Said the Time Ghost. His broad shoulders faced towards the red-clad man. "You want me to give you permission to allow this boy into your world?" The blue ghost turned to face the old man, his rubies eyes twinkled. "Just because your…Avatar?" The elderly man nodded his head to show that the ghost was correct. "Cannot handle the spirits that now roam the living world of your universe." The elderly man nodded again, his white beard dipping lower to the ground.

"Yes." The old man said, his voice deep and firm; but yet somehow soft and kind. "You're the boy's Guardian. So I thought it would be wise to ask for your permission before dragging him to somewhere that may harm him."

"Which it will." Said the Time Master as his from began to shift. The old man watched in mild awe as the Master of Time morphed from an adult to an elderly man. A long trail of white hair appeared on the older Time Master's chin, surpassing his purple cloak.

"You do realize what the boy is?" The older Time Master spoke, his voice deep and somewhat hoarse. The other old man nodded.

"Yes. That he is why he will be perfect." The red-clad man said seriously. "The current Avatar, Aang, needs help with the spirit problem in my world. A half human, half spirit person would be perfect. He would certainly benefit the Avatar's problem. And once the problem is solved, Aang would be able to send him back here."

"But I think you still fail to grasp the situation entirely." Said the other as the Grandfather clock in his chest began to swing a bit faster. "The child you wish to be sent into your world is a half human, half ghost hybrid. You see, there are differences between your spirits and our ghosts. Though they have many of the same qualities and abilities of each other, but each have their own extremes.

"Here, every ghost has the basic powers; just as your spirits. But, each ghost also has their own unique abilities that make them different from each other and an elemental core that would react to any dramatic changes at which the ghost may experience."

"Such as being teleported into a different universe?" The old man said. The purple cloaked elder nodded his hooded head.

"Yes. Definitely that. Danny, the one you wish to send to your world, his core is highly sensitive because of his…being."

"You mean him being alive but yet dead?" Said the foreign man. Once again, the other nodded his head.

"Sending him into a completely different universe would cause his core to react in a very painful way; harming him more than helping him. And not only will he be affected, but everyone else around him. Last I checked your spirits are highly attuned to nature and the emotions of the living. Imagine having a half spirit hybrid. His emotions would be completely thrown off and he'll eventually make everyone as irritable as him." At this, the blue ghost smiled slightly. "Though, it's hard to imagine him any more irritable as he is. I swear he's the most irritable ghost that I've ever met or watched."

It was silent while the other old man thought over what the local had just told him. If what he says is true…

"But he'll still be able to survive in my environment, right?" Asked the elder man. The other frowned as his form began to morph again.

"Right." Said the child Time Master. He frowned, his buck teeth showing. "But that still doesn't mean that he should go."

"Please, Clockwork." The old man said, his voice somewhat pleading. "I know you're a little protective over the boy, especially since the last time the Avatar of my world that seek your help didn't end well… But times have changed. There are none of them in my world anymore. That's why I-my world-need him. He's the only one who could help Aang control the spirit problem of my world." The Time Master frowned more and turned his small back towards the older man, watching a screen that showed a disheveled sleeping raven-haired teen. The older man saw the teen, a small smile appearing on his lips.

"You care dearly for him, don't you?" He asked, his pleading voice gone, replaced with a proud grandfather's. The Time Master nodded.

"Roku?" The Master of Time called out, using the older man's name for the first time that the foreigner had entered his universe. Roku's eyes traveled over to the child. The child turned, his blood red eyes stared at the old man.

"Do you swear that you'll watch over him while he's in your world?" The Time Master whispered his care for the hybrid so clear in his voice.

"Yes." Said Roku without any hesitation.

"Do you vow that Danny will only stay as long as his help is needed?"

"Of course."

"And, will you do anything to protect him when he is stuck and no one else can save him? Will you save him, if the situation arises?"

Roku was silent, thinking over the question before he finally answered.

"I shall; if necessary."

The instant that Roku said that, he felt like he had just made a deal; one that if he were to break, that he would lose his afterlife. But he most certainly isn't gonna back down. No. Aang needs help; and Roku knew that this 'Danny' was the answer to Aang's problem. His determination to protect the current Avatar burned the older man like lava. If he must, he will protect the halfa at any cost.

The two beings stared at each other for a few minutes, letting the silence rule the atmosphere. The child sighed as his form changed back into that of an adult's.

"I still don't like it; but if you're in that dire need of help, then so be it." Said the adult before he sighed. He looked up at the foreigner, his cold dead eyes calculating. "But, allow me to send him to your universe. Since I am his Guardian after all." Roku nodded his head.

"Of course." He said, sensing that the Master of Time isn't finished yet. The ghost nodded his head, a sly smile on his lips. He, then, raised his Time specter and pointed it at the previous Avatar.

"I, Clockwork, Master of Time of this universe, hereby allow Avatar Roku, of his universe, to take Daniel James Fenton, also known as Danny Phantom, along with him; his stay only lasting as long as the current Avatar, Avatar Aang, the last Airbender, deems that he no longer needs Danny's help and will return back home, to his own universe."

Now Roku really felt like he had just stroke a deal with the Time ghost, who smirked at the previous Avatar's discomfort. The specter was trained on the old man for a while longer before it was slowly lowered.

"There. Now if what had happened last time happens again; I will have full permission to have revenge." Clockwork said darkly. Roku swallowed a small gulp of air. He knows that the Time Master isn't being mean on purpose. The Time Master remembers the last time an Avatar had come for his help, thousands of years ago.

And he most certainly did not forget it.

"Of course." Roku said his voice quiet as he bowed at the Time Master; who returned it with a bow of his own. Though Roku has no idea how he could do it, for the ghost has no legs.

"I will send Danny to your world shortly." The Time Master said before a huge clock hand appeared. In one sweeping motion, the hand moved clockwise in a hurl of blue energy, making the Master of Time disappear. Roku stared at where the Master of Time once floated before him, too, disappeared from the ghost's universe…

And returned to his own.

In a blue hued bedroom in Amity Park of the United States of America, a huge clock hand appeared out of nowhere, turning in a full circle to reveal the blue colored ghost. The hand disappeared with a sliding door sound, the light disappearing along with it.

A gasp rang out in the dead silent room. The Time Master smiled fondly at the raven-haired teen as a light blue mist escapes the teen's lips, spiraling upward in the air until fading out. The teen shivered, his body instinctively curled into a ball as his teeth clattered, the device in his hand pressed tightly against his chest. Clockwork, still smiling, floated closer to the halfa.

As he neared the teen he frowned, seeing what Danny was clutching tightly to his chest was his new iPhone generation five. The Time Master wanted to take away the teen's phone; where the halfa would be going, there will be no need for it; but he halted his gloved hand, his smile grew sad.

Maybe it would better if Danny kept the phone; as a way someone would keep a picture. Clockwork knows that Danny-okay, mostly Sam-had taken pictures and stored them onto his phone; along with a movie and tons of games.

The Time Master's hand came closer to his own body, reaching for one of his cloak pockets. His hand quickly delved in and came back out just as fast, a necklace in his clenched fist.

But, of course it wasn't just any ordinary necklace; but one of his own inventions…

The Time Medallion.

Clockwork smirked, already knowing what Danny's reaction would be when he takes off the Medallion in hopes of instantly returning back to his home.

But it will not work this time. Clockwork thought to himself as he placed the necklace over the sleeping teen's neck, making the Medallion intangible so that it would easier for him. The Medallion will have a different purpose this time; and Danny will have to figure that one out the hard way.

His fingers brushed against the halfa's cheek, making the teen's eyes snap open. His sky blue eyes were wide in shock at the freezing cold touch until they landed onto the Time ghost. Danny visibly relaxed.

"Clockwork…" Danny mumbled, already falling back asleep, a smile on his face as his tired eyes stared dully at the Time Master. The Time Master sighed, a playful smile tugging on his lips.

"Good Evening Danny." Clockwork began. "So tell me; since when do you ignore your ghost sense?"

"Since when…ghosts…attack me….for…" At this, the teen yawned loudly. He, then, snuggled into his mattress, his eyes closed again. "…twelve hours…straight…." The Master of Time winced, already knowing the reason the teen was tired but asked anyways.

"But…." Danny mumbled out, somewhat trying to fight against sleeping in order to talk to his Guardian. "…you already knew that….didn't you…?" A proud smile crept on Clockwork's face.

"Yes, yes I did." The Time Master confirmed the halfa. Then he chuckled, making the teen's right eye open, frowning at the Time Ghost.

"Why…are you…laughing?"

"Because I'm happy that you're showing that you're not always clueless." The Time Master answered, making the teen rolled his tired eye.

"I'm fifth teen years old…Clockwork." Said the teen as to tell his Guardian the reason why his cluelessness is slowly diminishing away. "Plus, I've been…fighting ghosts….for over a year…now…."

"And with everyone knowing who you really are, ghosts aren't afraid to attack you anymore." Clockwork said gravely. Danny didn't need to reply to his Guardian, for its true. Ever since the world learned that Danny Fenton and Danny Phantom were one of the same; ghosts have been attacking him at any given second of the day.

Danny grumbled something unintelligible and closed his eye against his Guardian. The Time Master let out a sigh before speaking once more.

"But I've got some good news for you Danny." Clockwork whispered he hand began to tweak with his Time specter.

"Hm?"

"You're gonna have a break from ghost fighting." The Time Master said, looking over the halfa's casual clothes.

"That's…..good…." Danny mumbled out. Then he snored, signaling that he was asleep. The Master of Time let out a chuckle at how fast the halfa had fallen asleep on him. He pointed his specter at the young halfa, bright blue energy gathering in-between the two spikes from the specter's W.

"Yes, Danny." Clockwork said softly, getting ready to fire the energy at the sleeping teen. "That's very good." He said this as he fired.

The light blue energy flew towards the halfa, enveloping him like a cocoon. It caused no harm to the teen; in fact, it made the half smile as the energy settled. Then, like an old TV losing antenna reception, Danny's form frizzled from his bedroom; leaving the Time Ghost alone in the teen's room. He sighed, lowering his specter while pulling out a note out of his pocket from his other hand. He placed the note onto the halfa's bed, knowing that it would be the older sister to find the note. Clockwork paused, taking in the teen's room.

So many things could go wrong. Clockwork knew this. He cannot watch over Danny while he's in a different universe…unless it was during a solstice; but so many things could go wrong by then, and with Danny's luck, anything could happen…

For better or for worse...

Well, here it is. My own personal version of a crossover between Danny Phantom and Avatar: The Last Airbender.

Yeah, title is sooo original, right? Right, gonna figure out a better title as the story progresses.

And also using Clockwork as the one to send Danny to the world of Avatar. Totally original, right? Right?

Of course not.

Which reminds me, before the story even proceeds, I would like some reviews (yeah, I know I'm rude for asking for reviews flat-out). All I would like is to have at least five reviews to continue the story (just on this one chapter). Heck, the reviews can be just smiling faces for all I care, for all I really want to know if people are actually gonna read this.

Five reviews. And then I will post the First Chapter...if I get five reviews.

Okay, but yeah. I have been reading DP x ATLA fanfics and for the past few days, I've had a desire to do one of my own...so here it is.

Don't know why I'm doing another story, I'm still working on The Accident and Grim Reaper Chronicles, but here I am! Typing out a DP x ATLA crossover...sighs...

Oh, and before I let you guys go I'll have to...tell you something that deals with the (possible) continuation of this story.

First, I'm gonna torture the crud out of Danny.

Second, the story is gonna be in third person, but it's main focus is on Danny (cuz I'm obsessed with the ghost boy okay?).

Third, no weird pairings. Danny x Sam (though Sam isn't gonna be in here at all unless mentioned), Aang x Katarra, Zuko x May (I think that's right...), Sokka x Suki and Toph x... Toph x... T.O.P.H. x... . . . . . . . . ... Who does Toph ended up getting married to anyways? (Sorry, haven't been able to watch anything due to football season and college.)

Forth, DP takes place about half a year after Phantom Planet (Danny is 15, as stated in the story) and ATLA takes place a few weeks after the final episode (Aang defeats Sozin). So...isn't Aang like 13 or something?

Fifth... Gonna torture Danny some more. Yup. ^^
