Chapter 1 - Hunted

Breathe in, breathe out, inhale, exhale, her heart was pounding in her ears, beads of sweat forming on her temple and slowly making their way down the side of her face. Danielle—Danni threw a quick glance behind her, reassuring herself that she'd lost the pursuer, pausing to lean against the building's wall to catch her breathe. She couldn't take this much more…Constantly hunted, constantly on the run…From Amity to Seattle, and then down to Los Angelus, she'd been chased all up and down the coast, and by now she'd just had it. Ghost birds and hunters, all sorts of nut-cases, they always managed to sniff her out.

Danni straightened up, drawing on some of her last bits of energy; she had to get out, had to get racing. But how? Where? There didn't seem to be anywhere she could run, she needed a chance to just think it over, and what better time than now? She'd left behind her pursuer, and her ghost sense would warn her should it catch up. So for the time being she just stood there and thought, satisfied enough with her safety to spare a moment or two. She had to think of something, some place to feel safe. It was obvious that she wouldn't find it in the states. Vlad had far too much influence, his arm was long. She was almost certain that he'd manage to find her anywhere on the continent.

The only place she felt somewhat safe was in Amity, but she could not bother her 'cousin' by bringing her problems to him, he had enough on his plate with the local ghost plague. Maybe she just needed a change of location, a place where Vlad couldn't find her.

Two rings of blue white light formed around her waist, slowly traveling along her body and replacing her black and white outfit with a blue sweatshirt and red shorts. She shook out her now black hair and looked thoughtful for a moment, mulling over the new idea that was forming in her head.

"Maybe…" She mused aloud, periodically scanning for any unfriendlies in the immediate vicinity. Her ghost sense had yet to go off, so she considered herself relatively safe for the moment and wasn't too worried about being overheard. She began to search through her pockets, looking for anything that could help the idea evolve into a reality. Unfortunately her hunt only served to produce about a dollar in quarters and two nickels…not really enough for an airplane ticket, or even a bus fare.

One irritated sigh later and Danni started chewing on the inside of her lip, toying with a way to go through with her plan despite her lack of income. It would push her moral boundaries and it would be the first step toward using her powers for personal gain like Vlad did, but she was getting sick of being run all over the country, and her ghost half longed to find a place to claim as her own (Much like Danny's claim over Amity).

She was startled out of her thoughts as her breath hitched and pale blue smoke floated on the still autumn air. A ghost was nearby! Danni pulled herself together and ran to the end of the alley, the cold prickling feeling continuing as the ghost stayed within sensing range. The alley poured open into a much larger street, and the afternoon crowd was there as predicted, giving her enough cover to duck into—there were times she loved being so small!

She saw it as she looked up through the people around her. It was there, hanging in the sky like an overgrown vulture, but it wasn't the trio of birds that Vlad usually employed. Its countenance was far more sinister, and it was larger, far larger. The ghostly bird swooped lazily above the crowded street, but not one face turned toward it, because no full human seemed to see it. Fiery red eyes swept the oblivious people, searching. Quick thinking urged Danni to rip off her red hat, stuffing it inside the pockets of her baggy blue sweater. Red was a noticeable color, and would be far more likely to draw the ghost's eye than the black of her hair.

It worked, and she managed to give herself a mental pat on the back as the bird circled the street a few times, every time its eyes slid right over her as though she were nothing but a normal human going about her every day life. She had to resist giving a shout and yelling something about the bird's impaired eyesight but thought better of it. While the bird wouldn't hear her—it was flying away, probably following the ecto-signature of some other random ghost (every city had a few ghosts, but not many bothered humans beyond the usual 'haunting mischief', Amity was unique in that it really attracted the dangerous ghosts.) she didn't want to deal with the strange looks given to her by the people around her.

Danni watched the retreating green form before muttering to herself, "I hear Hawaii is quite nice this time of year."

Screw the moral problems, stowing away in the cargo hold of a plane wouldn't hurt anyone. She hated this game of cat and mouse, and what better way to escape than to leave the house?

Well, so far so good. After working out a few kinks in her plans Danni had wasted no time putting them into action. It was why she was now currently walking through the halls of one of Los Angelus' airports. Yes, walking. She'd changed her appearance somewhat, so if Vlad ever found a reason to look at the surveillance tapes he wouldn't recognize her right away. Once again the red hat was stuffed in her jacket, which was tied around her waist and hiding a good portion of her red shorts from the ceiling mounted cameras. A black tank top finished off her outfit, and the fact that she'd let her hair down completed the disguise. It wasn't fool proof; if Vlad ever got a really good look at her he would be able to tell with ease, but it was enough to hopefully keep him from needing a closer look.

Danni stopped in front of a large screen showing the departing flights, and scanned it for the one she was looking for, reading the names under her breath (she often talked to herself, after months without social contact she was pretty sure it was one of few things keeping her sane), "Gate 20…Flight 265 Beijing…21…Flight 323 Tokyo…22…Ah, Flight 332 Honolulu."

She took note of the gate and time before continuing through the airport halls, her stomach rumbling a little as she passed a few restaurants or snack stands. The ghost girl ignored it the best she could; only shooting one wistful glance before forcing herself to move on.

One might wonder why she didn't just move around invisible, it would do a far better job of erasing her tracks on the security tapes, and intangibility would allow her to just phase through walls directly to get inside the plane. The answer was a simple one, she didn't want to risk her powers short-circuiting before she needed them. Her DNA was still highly unstable, which led her powers to be unpredictable at best.

Danni finally reached the cluster of gates that included nineteen through twenty-nine, and eyed the security checkpoint warily. This was about as far as Danni Fenton could go (She considered herself a Fenton because of two points. 1) She was born from Danny Fenton's DNA and 2) She loved the Fenton/Phantom conversion) and so it was time to bring out Danni Phantom. The blue-eyed girl spotted a restroom not far down the hall, and used one of the stalls to initiate the change into her ghostly form. Luckily the bathroom was empty, so she examined herself in the mirror. Her two piece uniform was far too conspicuous to walk around visible. It wasn't quite as odd looking as Danny's (the male halfa's really was a one piece jumpsuit. At least Danni's could be mistaken for a shirt and bellbottom pants with a strange color scheme) but the symbol smack-dab in the middle of the shirt was known even as far away from Amity as Los Angelus, and along with her white hair and glowing eyes she didn't want to know what kind of rumors might be sparked that would end up traveling back to Amity, or more likely, Wisconsin.

A faint tingle spread throughout her body with nothing more than a thought, and her reflection faded from the mirror, indicating the invisibility was at work. Another silent command had a cold, numb feeling joining the tingle, reassuring her that intangibility was also working as usual. Danni turned away from the now-empty mirror and phased through the wall, she didn't have much time before there was a danger of her powers shorting out.

The security checkpoint proved to be little trouble, since she cut through the walls around the scanners. She wasn't sure if the scanners would pick up on her if she did try to move through them, but she really didn't want to risk it. She spent a little extra energy phasing through the walls and out onto the tarmac, the huge airplane parking lot. Danni scanned the gate numbers, remembering that nineteen through twenty-two was on this side and twenty-three to twenty-nine were on the other side of the terminal.

There were only two planes on the tarmac as she settled down on the pavement, not wanting to waste more energy on floating. The numbers that rose up behind the two planes were 21 and 22, which was weird since the departures list had stated that the flight to Beijing should have already been boarding. Danni shrugged, chalking it up to a mechanical error and started jogging toward the two planes she could see.

Upon reaching the gate she froze as the cold and numb feeling faded away, leaving her completely visible to the men working on loading the flight. Only one managed to spot her, and addressed her in a gruff, annoyed voice, "Now 'ow the hell did you get out here, missy?"

Later, she would admit that she could have handled the situation better, but going into the entire operation she'd been so nervous, and the short circuit of her powers sent her into a bit of a panic. She kicked off the ground and grabbed once more at her failing power. Amidst the man's gasp, invisibility worked, but intangibility refused to cooperate. Instead of phasing through the plane to get to the hold as she'd planned, she was forced to swoop through the steadily closing cargo-bay doors and dive right into the piles of baggage as invisibility frizzed out again, forcing her to return to her human form. Trembling from the effort, Danni decided to curl up in the maze of bags to regain her energy. A small droplet of green liquid formed on her forehead as she quickly placed herself into a deep sleep—it was the only real way to stop the degeneration before it started and began to suck away even more of her precious energy.

Meanwhile, the plane began to taxi out of the gate, the pilots unaware of the stowaway since the baggage worker decided to keep his mouth shut after the strange looks his companions gave him. He muttered something along the lines of 'Damn Heat' before turning to the rest of the crew, and jerking a thumb beyond the gate and to the smaller plane resting at the end of this section of gates—it had been hidden behind the much larger flight 323, "Alright boys, time for flight 332."

Danni woke up to the sound of voices, yelling at each other in a language other than English. Groggily she initiated the change, the white-silver beams flashing as she shifted into her ghost form. The groan of machinery coming to life soon drowned them out, and a faint light shone through a growing crack in the cargo doors as they began to grind open. The ghost girl groped for her powers and felt them respond, allowing her to rise up through the plane and exit out of the roof. Once she got above the airport's floodlights, she was shocked awake, staring out at the towering buildings, blazing with light even in the—probably—early morning. She could see some lit signs along the mostly empty streets, written in symbols she'd never seen before, but could easily read thanks to Vlad's tinkering.

'Tokyo Airport' The sign read as if it was English to her, easily and without thought. She'd noticed something similar with Spanish when she snuck a look at Danny's mostly unused textbooks, but didn't think much of it at the time. She wasn't really sure of what to think about being in a completely different country. On one hand, it was out of Vlad's sights, and he'd never think that she'd run to Japan of all places; she hadn't even thought of it herself. On the other hand, it was a completely different country…

Hopefully it wouldn't be that bad, she thought as she picked an empty looking street and transformed back to her human self, not wanting to waste anymore ecto-energy when she might need it later.

"Look at it this way," she began, using her voice to cover up the strange, unfamiliar silence, "I've always wanted to go to Japan."

Meeh, yeah, it's another story. I've had this idea in my head since I read that Ayumi thought the Kudou house was haunted and read the really wonderful DP/DC crossover that is the "The Impossible Murder" by Billie Jukes. If you haven't read it, go read it! It. Rocks.

Anyway, Danni is obviously the main charrie, but it's set in the DC-verse. Kaitou Kid will be in it obviously—actually, he'll have a major part—as will Conan and some of the other charries. I hope this little experiment turns out well. I don't have an update schedule for this though. A few chapters are written already but looking back on my other stories…/winces/ Well, all I can say is that I'm governed by my muse. Whatever I'm interested in is what I'm gonna write about. This is also my attempt to get me back into Detective Conan for Luck and Masq. It's kinda like piggybacking on my current Danny Phantom inspiration thingy…maybe it'll get me back into DC…

And yes, the title is a play off of the DC movie Phantom of Baker Street. Unoriginal, I know, but meh. I'm open for suggestions.

Here's to hoping someone likes this…

Edit (3/30/08): An anonymous reviewer recently raised some valid questions I would like to address here, in case it ever becomes an issue with future readers.

First off, the timelines. Danny Phantom wise, this takes place after Infinite Realms, but before D-stablized. Now, I don't know the length of real time between the two episodes, so I will be taking some liberties with that. Detective Conan isn't as definite, but somewhere before Movie 8.

Second, Danni's instability. I know basic powers usually don't cause shorts, but I figure if her energy reserves get too low even they will have issues. As of this chapter, and even the next, Danni has had little to no sleep, only the barest minimum of food (she has morals and only steals when she needs to) and has been living in a constant state of high alert-ness/fear since the events of Kindred Spirits. Given enough rest and food her powers will even out (with the exception of the more advanced ones) and flight/invisibility/intangibility will cease to be an issue.

I hope that helps clear things up!
