A.N. - Hello! Thank-you to everyone who read and especially reviewed! I really appreciate it, even more so since this story is only a couple days old.

I wasn't planning on adding to this story, but I might leave it as a an open fic - adding to it when inspiration strikes. I'm sorry for those who are Ember/Danny shippers (which seem to be most of my reviewers, ha) because that relationship is not the main focus of this story, and while I have an idea for those two interacting in the next chapter, it won't lead to that relationship. Though who knows; if I've learned anything in my past 10 years of writing it's that stories often have a mind of their own.

Anyway, I hope you enjoy this chapter just as much!

Danielle knew the instant a ghost showed up. A shiver ran through her body and she gasped, releasing a small blue puff of air.

With a grin, she jumped up from her brown wooden desk and transformed, letting two white lights wash over her body and change her into her ghost form, Dani Phantom. Her shoulder-length black hair (layered with triangle cuts in the back) became white, and a black-and-white jumpsuit replaced her purple pajama shorts and button-up top.

She turned intangible and flew up through the ceiling of her bedroom - created by siphoning off sections of the Fenton family's lab - until she reached her older cousin/brother/creator Danny's room. She poked her head through his floor just in time to see him finish his own transformation into Danny Phantom.

"Hey!" Dani called, startling him and making him jump up into the air. Hovering there, Danny looked over at her.

"What's up, Elle?" he asked. Ever since she had moved in with the Fentons a year ago as their adopted daughter, the family had taken to calling her Elle, Ellie, or Annie to differentiate between her and Danny. Dani didn't mind, but she still introduced herself to new people as Dani-with-an-I, and she would always be Dani Phantom.

"I got this one," she answered Danny. "Go back to studying."

"But - "

"I can handle whoever it is, I promise," Dani insisted. "That's the whole reason you went into the Ghost Zone the other day, right? To make sure they'd leave you alone so you could study?"

"Well, yeah, but -"

"Then study. These exams are really important to you, I know."

Danny lowered himself until he was back on the floor. He glanced over at his desk, which was covered with pencils, textbooks, and loose-leaf paper filled with scientific equations. "I mean...this can wait. You have homework, too, I know. I'll just stay up and -"

Dani sighed loudly and rose up out of the floor. She narrowed her glowing green eyes - the same as Danny's - at him. "Danny. Please. My Pre-Calc homework is not going to determine whether I graduate or get into my dream college program this week. Just let me. Handle. The ghost."

Danny stared at her for a moment, looking torn, before he finally sighed. Twin flashes of light raced up his body, and his eyes turned blue, his white hair - cut shorter and closer to his head than when he was 14 - became black, and his own black and white jumpsuit disappeared to reveal a NASA T-shirt and a pair of blue boxers.

"Alright, you win," he conceded. "Just...be careful. And you'll get me if you need help?"

Dani rolled her eyes. "Yes, Dad, I promise. Now go do you homework!"

Danny chuckled. "Alright, Mom." But he waited and watched as Dani pulled out her phone and quickly shot off a text to Valerie, saying the exact same thing she'd told Danny, before turning intangible again and flying through the roof.

Bursting into the night air, Dani took a second to enjoy the rush of flight, before putting herself into a fighting mindset. Looking around at the houses, clearly illuminated by the giant green Fenton Works sign attached to the Fentons' home, Dani couldn't see any signs of a recent ghost attack. No broken windows, no smoking buildings, no screaming people.

But she'd definitely sensed a ghost earlier. Maybe it was something small? Or it was still in the lab? Now that she thought about it, she should have just checked out the lab first, especially since it was right next to her bedroom. But she'd wanted to make sure Danny didn't go after the ghost himself. He'd been super stressed over his final AP Chem and AP Physics tests this week and she had wanted to do him a favor by taking care of any ghostly threats that came through.

Not to mention it would show him and the rest of Team Phantom that she was mature and skilled enough to protect Amity without any of them breathing down her neck. Honestly, she loved her cousin, and Sam and Tucker and Valerie, but sometimes they were way too overprotective. They acted like she hadn't spent over a year living on her own, fighting ghosts and for her own survival. And they had been worse lately; their impending collegehood must have been making them too nostalgic and worried and adult-like.

Dani was about to head back inside, when she gasped, her Ghost Sense alerting her once again. Then, sensing something coming towards her from behind, she dodged to the left - just in time to avoid the grappling hook/claw that zipped by her. It landed in the sidewalk down below, cracking the concrete.

Dani spun around, following the mechanical line up from the hook to the ghost who had fired it. When she saw who it was, she groaned.

"Oh, come on, Skulker? Really? Do you know what time it is?" she demanded.

"Ah, the Ghost Girl. Nice to see you. I'd been planning on hunting your sire, but a fight with you should warm me up nicely!" Skulker exclaimed. He pressed a button on his suit, and the grappling hook shot up from the sidewalk and returned to Skulker with a hissing sound. "And, yes, I know it's late. My apologies. Believe it or not, it's morning right now in the Ghost Zone."

Dani rolled her eyes. "Yeah, yeah, whatever." Floating higher until she was eye level with Skulker, she prepared her own ecto-blast, green light coiling around her hand. "Also, how many times do I have to tell you, Danny is my cousin, or maybe my brother. He's not my sire. That makes him sound like a medieval king or something. It's weird."

Skulker chuckled. "You're more right than you know, child." Then, raising his arm to ready an ecto-energy cannon blast, he added, "Now, enough talk. Let the hunt begin!"

Danielle smirked. "You're on."

She took aim at the center of the robotic suit and launched her ecto-blast. Skulker simply dodged it, and fired his own attack. Danielle turned intangible and let the cannon fire pass right through her. Undeterred, Skulker launched a type of flaming arrow, burning with his signature green-blue fire.

I should probably move the fight away from the neighborhood so nothing gets too damaged, thought Dani. Dodging the small projectile and flying over near the park, she asked,

"Didn't you get the flyer?"

"Of course I got the flyer. The Ghost Child littered them all over my front lawn!" Skulker exclaimed, shooting out three more rockets from the launcher on his right shoulder.

"And, what, you just decided to ignore it? That's so not cool." Dani reached out her hand and encased the rockets in her ecto-energy, containing their explosions; smoke billowed within the green spheres as she lowered them to the ground.

Dani then flew towards the park, where there would be less people to hurt and less buildings to damage. Skulker chased after her, donning a pair of night-vision goggles, even though there were still street lamps in the park.

"I thought you guys were allies sometimes," Dani added, stopping in mid-air above one of the public fountains. She could hear the water gurgling slightly in its concrete bowl.

"Yes, when the fate of the Ghost Zone is at stake," Skulker answered. He hovered on the opposite side of the fountain, arm outstretched towards her. "The whelp failed to explain in his flyer how him failing a test would be the end of the world."

Dani narrowed her eyes at the hunter. "It'd be the end of his world," she told him. She held up both hands and formed two more ecto-blasts. "What's important to Danny is important to me, so I'm not gonna let you ruin this for him."

"How admirable." Skulker fired another blue laser at her, which she dodged. She released her ecto-blasts, hitting Skulker in the chest. He crashed into a nearby tree, breaking the poor plant in half. When Skulker remained on the ground, Dani hovered closer to him. Placing both hands on her hips, she said,

"You don't plan on following him to college, too, do you? 'Cause that would be even more uncool."

Skulker merely grinned at her from among the wood splinters. "But of course! Where the prey goes, the hunter goes. The whelp doesn't think he can shake me just by going to a different learning institution, does he? How foolish!"

Dani fired another ecto-blast at him. He yelled in pain as it hit, pounding him into the ground. Dani smirked as the dust settled. That oughta teach him.

Only to widen her eyes in surprise when she saw that Skulker was no long on the ground. "Wha - ?"

A presence behind her. She looked over her shoulder just in time to see Skulker's grin before he backhanded her, sending her crashing into another tree. Dani groaned as the tree fell, sending a shock wave of pain up her body. Spitting out leaves, she gathered herself, then rose up into the sky.

"Alright, Skulker, not ba - aaahhh!" Dani screamed as a ghost-proof net wrapped around her, knocking her back onto the ground and sending bolts of electricity through her body. She was left panting and jittery once it passed.

"Haha, you underestimated me, didn't you, Ghost Girl?" Skulker crowed as he walked towards her, his metal boots crushing the grass underfoot.

Danielle scrunched her eyes in pain, before opening them and glaring at the ghost hunter. She wriggled in the net, frustration building as she failed to free herself.

Skulker picked up the net and Danielle, holding her as if she weighed nothing. She'd gotten a bit of a growth spurt once she'd turned fourteen, reaching Danny's old height, but Skulker was still much larger than she was. Well, his suit was, at least.

"You know," Skulker began, regarding her thoughtfully, "I've never understood why you cling to human traditions so much. You, Phantom, even Plasmius - you all plan and prepare for human lives, human futures, but why? You're ghosts. And sure, lots of my neighbors concoct plans for world domination - even I like the occasional vacation out in the human world. But ultimately, we all belong in the Zone. Even you three."

Dani blinked up at him, surprised by his sudden philosophical demeanor. Even as she huffed and struggled in the net, she couldn't help but agree with him. There were times - when she was flying, high above the earth, or slipping between buildings without a care for the laws of physics, or using her powers to fight ghosts intent on doing evil - she wondered why she wanted to be human. Why did she want to pretend to be an ordinary girl, when there were people like the Guys in White that would capture and dissect her and her cousin the first chance they got? Why should she hide herself in this world, when in the Ghost Zone no one cared that she was part human?

But then...

Then she remembered the look on Danny's face as he taught her how to use her powers to help people. How excited he was to receive the acceptance letter from Amity University, contingent on his grades though it was. The joy and pride Danielle felt when Jack and Maddie welcomed her into their family, ghost powers and all. Going shopping with Jazz, and having her explain things like bras and periods. Hanging out with Tucker, Sam, Danny, and Valerie, listening to them joke around and plan for the future, even as they made Amity Park a safer place.

Dani sucked in a deep breath. "Skulker, you're right," she said. "We are half ghost."

Then, hoping she was right, she transformed. The white rings washed over her, her ghost side tucked away for now, leaving her in all her human glory. And - to her delight - as soon as she was human, Dani fell out of the net.

She landed on her feet, and smiled up at Skulker, who looked confounded. He must have forgotten to use the anti-halfa net instead, or perhaps, like usual, he had underestimated her.

"But we're also half human. And so we decide where we belong."

Mid-transformation, Dani jumped up and decked Skulker in the face. The ghost sailed to the left, gouging a trench into the earth as he landed. Before he could get up, Dani unhooked the mini-Fenton Thermos she always kept with her from around her waist and aimed it at the ghost. The thermos' opening shone brightly, its light sucking Skulker up into its metal confines.

"No! No! I'll get you for this, Ghost Girl! You and the whelp!" Skulker thundered, his words becoming quieter and more distorted as he disappeared into the thermos. Dani capped it and twisted firmly, sealing him inside.

The night became quiet once again. Dani surveyed the former battleground, pleased to see that the park had sustained little damage, outside of a few broken trees. Hooking the thermos back onto her belt, she rose into the air and headed home.

Danielle didn't know where she quite fit in yet - in town, in school, in life - but there was plenty of time for her to discover that. Right now, all she wanted was to stay by her family and friends' sides. And if the the price for that was battling a few ghosts and sticking them in Fenton thermoses - for at least six months, she thought gleefully, imagining Skulker's misery -

Well, then it was a price she would gladly pay.

A.N. - This chapter was originally supposed to be a fun, witty banter-filled battle between Dani and Skulker. But then somehow it became longer, more serious, and existential. Sorry about that, I guess?

Anyway, I hope you liked it. Reviews, comments, questions, and suggestions welcome! I'd love to hear your thoughts on this!

Also, I watched episodes "Girls Night Out" and "Torrent of Terror" after I wrote the first chapter, which totally reinforced for me the idea that Danny and (some of) his enemies have a somewhat playful relationship - Johnny 13 literally left the Ghost Zone to "blow off some steam" and thanks Danny for the "game" before returning ("GNO") - and that Danny is known throughout the Ghost Zone and ghosts can sense more power from him, as a powerful ghost criminal Vortex knows who Danny is and was "expecting a more electrifying performance from" him ("ToT").

So. Just saying. ;)
