Author's Notes: Welcome to my very first crossover! I love the idea of these two worlds colliding and I'm having so much fun writing it. And just so you know, this is a Fem!Danny fic. But as to not confuse the readers too much, this Danny spells her name like the guys' version b/c she likes it better than "Dani" with an "i". Hopefully that's not too confusing, or odd for you readers out there. Other than that, ENJOY!

Of Ghosts and Guardians

Ch. 1 "I See The Light"

It had been a relatively peaceful day for Danny. Sure, she had been nearly electrocuted by one of her parents' crazy inventions during breakfast. But it did miss her. And sure, Dash had shoved her into the school's trophy case only to be mocked by the other jocks and scolded by the teachers for her clumsiness. But the school nurse gave Danny an ice pack for her injured shoulder.

And let's not forget that Danny had gotten detention, for the third time this month, on account that she had skipped her entire 5th period class. But that wasn't really her fault either-she had been busy fighting off ghosts the entire time. Heck, half the school had migrated to the streets to watch the spectacle unfold. Who knew that any of the teacher's were keeping track?

But this was the life of Daniella Fenton a.k.a. Danny Phantom. Yes, she spelled her name like the boys' version. She always thought it looked better than just "Dani" with an "i." She was funny that way.

For over a year Danny had been using her ghosts powers to protect her home town of Amity Park from the various ghost and evil spirits that would do the town harm. And as Phantom, Danny had become quite famous. But as Danny Fenton, not so much. She was constantly being harassed in and outside of school by nearly the whole football team but most notably by Dash Baxter, the rest of the team just follows him.

Life was tough for Danny and it was about to get even worse.

"So Lancer gave my parents the mandatory phone call informing them of my 'repeated disregard for attendance,'" Danny said. Mocking her teacher, Mr. Lancer's voice. "And now my parents are waiting for me back home. Where they'll give me the mandatory talking-to."

It was now the early afternoon. School had let out and Danny was walking home along with her two best friends, Sam Manson and Tucker Foley.

"Don't forget the mandatory grounding." Tucker chimed in. Sounding very plucky.

"Thank you, so called best friend." Danny said.

"Hey. Real best friends tell it like it is." Tucker replied.

Danny narrowed her eyes at him. She could have sworn that Tucker was taking too much delight in her misery.

"Okaay." Sam pushed the two teens away from the other. The young goth was hoping to quell any impending arguments. "So, will that cancel our weekend plans?"

"No. It shouldn't. It's only Tuesday. They might not ground me for the whole week." Danny answered.

"But to be safe, let's not say anything about the party. Just in case your parents get any ideas." Sam suggested.

"Agreed." Tucker said.

"Great." Danny shrugged. Running her fingers through her dark scruffy hair. "Back to the party. What're we doing for the menu-"

Danny's words were suddenly cut short by the most violent tremor that she ever felt.

People all around started screaming. The sidewalk shook until it began to roll like ocean waves, knocking the teens, and everyone else, off of their feet. Danny watched in horror as the same thing happened with all the other streets.

Cars were swerving out of control. Some cars went crashing into their neighbors. Others were careening into lamp posts and fire hydrants. Danny even watched one car pull a wheelie and drive on its right side tires. Most were just trying their best to not hit any of the pedestrians. It horrified Danny to watch her town get turned upside down like this.

Danny laid prone on the sidewalk with her friends. Gasping, she looked to Tucker and Sam who were as panicked as her. Danny desperately wanted to use her ghost powers to try and save everyone. But the violent quaking kept her from concentrating properly.

That was when a blinding light filled the sky. Funny thing was, no one else seemed to see it. While everyone else was screaming about the earthquake, Danny focused solely on the light.

It was a perfect blend of silver and gold. And it moved through the air like liquid mercury, trickling through the ripples in the air and rapidly bleeding out from its unknown source.

In the very center of the light there was a core. The core grew to an intense shade of white and to Danny's astonishment it started to move. The white core bubbled and turned like boiling water in a kitchen pot. It didn't take long for the core to bubble over and explode.

Next several dark writhing figures shot out from that dazzling light. There were even so many that Danny never noticed a lone shadow emerge from the light and immediately disappear in a smokey haze.

The remaining figures seemed to chase after a single small beam of light. That single little beam shot out like an arrow and dove straight for the intersection. Danny gasped in horror. Whatever it was, it was about to get hit by who knows how many cars.

Danny willed herself to move and went intangible. She raced, propelling herself with her ghostly powers out into the intersection and scooped up the little being wrapped in light. When Danny reached the other side of the street her momentum sent her rolling several feet before finally stopping.

She could see the confused, and slightly horrified, looks that her friends were giving her. Danny merely nodded to them, signaling that she was alright, and held the little being close to her. She would explain when things calmed down. For now, Danny was counting her blessings that no one had noticed what her little in the midst of all the chaos.

Next Danny turned her attention back to the intersection. There were several black ghostly figures that stood there undulating. Danny noticed that they were beginning to panic. At first she thought it was because their intended target suddenly vanished. But then she saw that the same silvery light they emerged from was actually killing them. Danny went wide-eyed as she watched the dark figures dissolve away into little golden flecks of dust.

Soon all of the shadowy figures were gone. Along with the blinding light in the sky and the massive earthquake. Danny was left breathless from the sight.

As Tucker and Sam rushed over to her side, Danny looked down to the tiny figure that she had just saved. The silvery light had dissipated and left what looked like an unconscious green hummingbird in the palm of her hand. Danny examined the creature more closely and found that it had pink fairy-like wings and that one of those wings was severely broken. That

"Just what in the hell were you thinking?! You could've-" Sam bit her lip and she willed her anger to lessen. "You could've been seen."

"But I wasn't." Was Danny's only response. She knew what she did was stupid and that Sam had every right to yell in her face. Tucker gave her a disapproving look as he offered Danny his hand.

"But dude, why'd you do it? And did you hurt yourself?!" Tucker saw how Danny held her left hand over her belly like she might have been in some sort of pain. Sam gasped when Tucker mentioned it and began assuming the worst.

"Are you alright? What happened?"

"No, nothing happened I'm fine. Didn't you guys see any of it?" Danny asked of her friends. Tucker and Sam looked to the other with questioning looks on their faces before answering.

"What? You mean the city turning into a spaghetti noddle?" Tucker said.

"Or you dive-bombing at the street?" Sam said.

"I'm serious! You mean you guys didn't th-oof!" Danny got interrupted by a hurried passerby who had just shoved her. The three teens took a look around themselves. It had just hit them that the entire city was in a real serious panic. They weren't going to have long to talk before their parents came looking for them. Danny took her friends down a nearby alley to talk more. "Neither of you saw that light, or those shadows?"

"Nope." Tucker said flatly. Sam just raised an eyebrow at Danny.

"Really guys? You didn't see any of it?" Both Tucker and Sam shook their heads. Danny sighed. "Well, it doesn't matter anyway. Not right now. At least I know what caused the earthquake."

"Great. What was it?" Sam asked.

"I, I don't know exactly. But I think that light was some sort of portal. 'Cause all of these weird shadows just came out of it." Danny explained.

"Well, why would they?" Tucker asked.

"For this." Danny held out her hand to show her friends the little feathered creature.

"Uhh, Danny. I hate to tell you this but there's nothing there." Tucker said.

"What?!"

"He's right. All we can see is your empty hand, Danny." Sam replied.

Danny let out an aggravated sigh. "You gotta be kidding me." She mumbled. Her aggravation was short lived when all of their cell phones started going off. All of the teens checked to see that it was their parents calling.

"Dudes, I've got to get home." Tucker was looking worried.

"We all should. Make sure you tell us everything later." Sam ended with a look towards Danny.

"Count on it." Danny was especially determined to figure things out. She had so many questions. Starting with why she was the only one who could see what had happened. But she saved those thoughts for later. Right now she needed to go home and that was exactly what she did.

When she reached her house the little bird-thing had woken up. It was making a series of excited chirps and tweets. Danny felt like panicking even though it was obvious that no one else could hear or see the Little Bird.

"Hey, shush now." Danny whispered to it. "I don't want my parents finding out about you. Even though they probably won't see you either..." As Danny's voice trailed off and the Little Bird responded by giving her a haughty look. "Hey! No sass. That's supposed to be my job." The Little Bird gave an amused chirp. "Just be quiet now-"

"DANNY!"

Danny had barely stepped onto the front porch before her parents had opened the door and dragged her inside. Mr. and Mrs. Fenton had instantly taken to hugging and sobbing over their youngest daughter. They had felt the immense earthquake at their house and were rightfully scarred for Danny's safety.

"Oh, sweetie. We were so worried about you." Mr. Fenton cried.

"What happened out there? Are you alright? Did you get hurt anywhere?" Mrs. Fenton asked.

"G-guys, I'm fine." At the moment, Danny was much more concerned with the Little Bird who was being squashed inside of her coat pocket. The Little Bird was tweeting painfully aloud. But when Danny tried to push her parents away, they automatically assumed the worst.

"Oh, my goodness! Danny, what's wrong?!"

"If anything happens to you-I, I, I don't know what I'd do! You were always my favorite." Mr. Fenton sobbed painfully. "Oh. Hi, Jazz. Look, Danny's fine now!" Mr. Fenton's emotions flipped like a light wired to a plastic switch.

Jazz gave her father an disapproving look before turning to Danny with great concern. "You alright?" She asked softly.

Danny had finally managed to pull away from her parents and answered her sister sheepishly. "Y-yeah. I'm fine. I just don't know what happened. That earthquake and all of that ligh-I mean, yeah, I don't know."

Danny nervously touched the back of her neck. She knew her parents were worried about her but Danny wasn't even thinking about the earthquake. The worst part was that she knew she couldn't tell her parents anything about what really happened out there.

Jazz saw her sister's condition and gave the young teen a reassuring smile. And it helped. Instantly Danny was relaxed again. Jazz knew that her little sis would fix whatever was happening. She just needed a some encouragement every now and then.

Mrs. Fenton gently turned Danny back around to talk to her again.

"Danny, we're so, so happy to see that you're safe and sound. And about the call from Mr. Lancer earlier," Danny began uttering curses in her mind. "We'll let that one phone call slide. But just this one time."

Danny raised her eyebrows in surprise. Really, she thought, she was getting off scott-free?

"Just don't do it again." Mr. Fenton added sternly.

That's more like it, Danny continued in her mind.

"Right. Won't happen again." Danny said to her folks.

"Good." Mr. and Mrs. Fenton said in unison.

"So, umm, if we're all done here, then I'd like to talk with Jazz now. In my room. Alone." Danny said looking directly at her sister.

"R-right. Sure thing, Danny-ow! Hey!" Danny grabbed hold of Jazz's arm and dragged her up the stairs and into her bedroom. Once they were in the room, Jazz was freed from Danny's vice-like grip and Danny slammed the door shut. "Geez, what's with you? And what really happened out there? I mean, there's no way you'd be freaking out if this was just a normal earthquake."

"You're never gonna believe what happened." So Danny told Jazz everything that happened during the earthquake and even presented the little green bird creature, who was completely invisible to Jazz's eyes.

"You're right. I don't believe you." That earned Jazz a menacing look from her sister. "There's nothing there, Danny! What do you wan't me to do? Lie and say that 'yes I see this weird little bird thing?'"

"Or you could trust me!"

"I do trust you, Danny. I just can't see whatever it is you're seeing." Jazz placed her hand on Danny's shoulder in a very comforting manner.

"But that still doesn't help you to see her. Wait a minute, help you to see-THAT'S IT! I know how to help you see her!" Danny exclaimed. She gently set the Little Bird, who had been sitting in Danny's palms this whole time, down onto her pillow. Next Danny clapped her hands together and bother her eyes and hands glowed an icy shade of blue. The Little Bird chirped in astonishment-she had seen that very shade of blue only one other time. When Danny was done she'd created a perfectly rendered ice sculpture of the Little Bird and handed it over to her sister.

"Yikes! Its still cold, Danny!" Jazz tossed the ice sculpture back to her sister. Danny apologized and held it close to Jazz's face so she could examine it. "Wow, its so small."

"Yeah, well, this is her actual real-life size." Danny explained.

"And the wing is busted up pretty bad, huh?"

"Yeah." Danny recollected the Little Bird in her free hand who then jumped to stand next to the ice sculpture. "Can you see her yet? She's standing right next to her ice twin."

"No I can't." Both Danny and the Little Bird looked to the other a little sadly. "But, hey! You can still she her right? Maybe you should try communicating with her. Who knows what we'll learn."

"We?" Danny repeated.

"You're still going to tell me everything. Even if I can't see her, I want to learn all I can." Jazz said with her arms crossed.

"Alright then." Danny set the ice sculptor down on her side table and turned to the Little Bird. "Let's start with your name-oh!"

"What? What is it? Is she talking to you?" Jazz asked excitedly.

"No. No, she's challenging me to charades." Danny laughed. The Little Bird tapped her elbow and then raised her hand to hold two of her little fingers high.

"What is it? What's going on? Ooh, I hate not seeing this!" Jazz pouted.

"She's saying that her name has two words. First one is, is,"

"What? WHAT?"

"Chill would ya! She's holding something, no? Hugging? Still no? What is that, cradling something?"

"Like cradling a baby?" Jazz interjected. The Little Bird chirped excitedly.

"Jazz! You did it! The first part is 'Baby.' Second part is-wait, what are you pointing at now?" The Little Bird opened her mouth wide and pointed to her teeth. "Your teeth, tongue? No, your teeth. Or maybe just your tooth?" The Little Bird gave a loud cheer and began to clap as she bounced in Danny's palm. "Okay, okay! Tooth its is then!"

"So, what? Her name's 'Baby Tooth?'" Jazz asked.

Danny wasn't really sure either. She turned to the Little Bird with skepticism across her face. The Little Bird simply smiled and nodded.

"Yeah. That's her name. Baby Tooth." Danny replied.

"Baby Tooth, huh? How about that." Jazz said.

"Wow. Baby Tooth." Danny looked to Baby Tooth who continued to smile kindly at the teen. Danny returned the smile and said:

"Its nice to meet you, Baby Tooth."
