Before Phantom Planet. Post D-Stabilized.

I don't own Danny Phantom.

"Oh, please! Even Klemper can beat Boxy in a fight any day!"

"Yeah, that doesn't make him more annoying!"

Danny sighed and rested his hand on a table in the lab before he spoke into the phone again. "Fine. Klemper's more annoying than Boxy."

"Yes!"

Danny sighed again. "So, Dani, where are you?"

Maddie and Jack glanced at Danny from across the lab. Their son was a mystery to them. A simple action confused them. For instance who was this "Dani" person he was talking to? He was almost as confusing as the Ghost Boy.

Phantom. The world's most confusing ghost. He could disprove a decade's worth of research with a single battle. He made ghost hunters rethink all their bases daily. If they hadn't seen Phantom shoot ectoblasts out of his bare hands, fly, and glow, he could pass off as a normal teen with white hair.

"Las Vegas?" Danny asked, disbelief in his voice. "You're in Las Vegas?" He paused as if remembering something. "Wait a second. What are you doing in Vegas!"

The girl on the other end of the phone said something. Danny pinched the bridge of his nose and took a deep breath.

"Danielle! I know I'm not your dad and, no, I don't want to get my butt kicked into the Zone, but you're like a little sister to me and I care about you," Danny said. "Dani? Dani?" The teen looked at his phone and sighed as he hung up. "Danielle…"

The teen started to walk towards the stairs but paused.

"Jazz? What are you wearing?"

Jazz was in a black tank top with a white leather jacket over it. She also wore a black miniskirt with a white belt over white leggings. On her feet were black boots. Instead of her normal headband she wore a white one.

"I made a bet with Sam," Jazz said. "To see who could catch Boxy the fastest. I got him in seven minutes. Sam got him in six."

Danny grinned and folded his arms. "Doesn't beat my record. Thirty-two seconds."

Jazz rolled her eyes. "Well, you've got an unfair advantage."

Danny stuck out his tongue before walking upstairs.

Jazz rolled her eyes and grinned as she walked up to her parents. "Hey, Mom. Hey, Dad. What are you working on?"

Jack grinned as he finished what they were working on. "It's done! The Fenton Portable Portal is done!"

Jazz looked at the device. It was larger than the portal they had made in college but a lot smaller than the one in the wall. "The Fenton Portable Portal?" She asked.

Maddie nodded. "As the title suggests, it's a portable version of the Fenton portal."

Jack grinned. "And now to test it."

He plugged it in and flipped the "ON" switch (It's not on the inside this time! :-D)

The machine charged up… and suddenly began to glow green.

"Is it supposed to do that?" Jazz asked.

Maddie shook her head. "RUN!"

Too late. The Fenton Portable Portal exploded, electricity and ectoplasm flying everywhere.

Unfortunately, the lab was soundproof, so Danny didn't hear the screams of his three family members.

…

Jazz was the first to wake up. The lab was covered in ectoplasm and completely trashed. Danny was staring at her, blue eyes wide.

"Danny?" She asked weakly. "What's wrong?"

Danny kept staring at her. "Uh, Jazz? We've got, um, a Problem Number 34?" It came out more of a question.

Jazz gasped and looked down at herself. Her outfit had switched colors and, by looking in a mirror, she saw that her eyes were radioactive green and her hair was white.

Panicking, she ran over to Danny, grabbed his shoulders, and shook him back and forth. "Danny! Change me back! Change me back!"

Her yelling woke Jack and Maddie up. When they saw Jazz's ghostly appearance, they screamed. Then they looked at each other and screamed.

Both had the same bright green eyes.

Jack's hair was white where it had been black and black where it had been white. His HAZMAT suit was white with black accents (where it had been black before).

Maddie's hair was white and her jumpsuit was black with white accents.

The couple looked at Danny (whom Jazz had stopped shaking and was now dizzy). "Danny! Stay away from us! We're evil ghosts!"

Danny cleared his throat. "Actually, you're halfas. Easy mistake."

"Halfas?" Jack and Maddie asked confused. "What's a halfa?"

Danny sighed. "You got into an accident, right?" He looked around. "I can tell by the way the lab looks. Well, anyways, ectoplasm somehow got fused to your DNA, turning you into a half-ghost half-human hybrid. Commonly called a halfa."

Maddie laughed. "That's impossible, Danny! Humans can't have ghost powers."

Danny grinned as he reached into his pocket. "If humans can't have ghost powers, a certain protector, a certain evil vampirelike ghost, and a certain little girl wouldn't exist." He pulled out a pair of Fenton Phones and put them on. "Sam? Tuck?" he said. "We've got a Problem Number 34. Meet at Fenton Works."

"Sam and Tucker?" Jack asked. "They know about this 'halfa' thing?"

Danny nodded. "Of course. They were there when one was created."

"Were you there?" Maddie asked.

Danny rolled his eyes. "Of course I was there!" He smirked to himself.

The teen reached into his pocket and grabbed his phone. He quickly dialed a familiar number. It rang a few times before the person on the other line picked up.

"Hey, Danny."

"Danielle! We've got a problem."

"Is it Vlad?"

"No. A new halfa problem."

"What?!"

"Yes. Now Danielle Jamie Phantom, you fly at top speed to Amity Park. Right now!"

"Yes, Mother," Danielle said, voice dripping with sarcasm before she hung up.

"Danielle Jamie Phantom?" Maddie asked. "Is she related to the ghost kid?"

Danny smirked to himself again. "They call each other third cousins once removed. But I know that that's not their real relationship."

"Well then what's their relationship?" Jack asked confused.

Danny kept the smirk. "Oh, you'll find out within the next hour. Danielle's a halfa. The youngest halfa, before Maddie and Jazz, the only girl, and the only one who did not become a halfa by ectoplasm accident gone awry."

Suddenly, a blue wisp flew out of Danny's mouth and a red one flew out of Maddie's. Danny looked at the red mist.

"Mom, you've got a hot core. And are going to have fire powers in the future," Danny explained. He then sighed. "I know that's you, Danielle."

A little girl appeared. "Aw, c'mon!"

Maddie and Jack gasped. The girl looked like she could be Phantom's identical twin if she was older. She had white hair in his hairstyle with a ponytail. Her HAZMAT suit had a long-sleeved white and black top that cut off at her midriff and had the DP symbol. She wore a black glove on her right hand and a white one on her left. She had on black pants with white boots.

She looked at Maddie, Jack, and Jazz. "Hi! You must be Mr. and Mrs. Fenton and Jazz. I'm Dani with an I."

"Hey, Dani," Danny said, grinning. "Why don't you transform. To prove that halfas exist."

Dani smiled and a white ring appeared around her waist. It changed her top to a blue sweatshirt, her pants into red shorts, and her boots into blue sneakers. The ring went up to her face and changed her eyes to a baby blue and her white hair to raven black. The halfa girl grinned and waved.

Maddie and Jack stared at the girl. "B-B-But…"

"How do you transform back?" Jazz asked.

Dani shrugged.

Danny grinned. "You really just think of going human again."

Jazz focused and a white ring formed at her waist and split, transforming back into her normal clothes. "Yes! It worked!"

Maddie folded her arms. "And how exactly did you know about that?"

Dani and Danny looked at each other and grinned. "Goin' Ghost!"

The white ring appeared around both of their waists. They split giving way to the HAZMAT suits and changing their hair to white and their eyes to green. The new Dani and Danny stood straighter, stronger, and prouder.

Maddie and Jack stood there gaping.

Danny held up a gloved hand. "And before you ask, the mayor was overshadowed, actually had me in a headlock. Theft? Controlled by the Circus Gothica ringmaster. His staff could hypnotize ghosts and halfas. Any questions?"

"H-H-How?" Jack asked.

Danny didn't say anything. He just pointed to the portal in the wall.

Maddie slapped herself in the face. "The portal! Of course!"

Jazz grinned. "Next time you want to make a portal, put the ON button on the outside."

Jack groaned. He then paused. "Wait. Then who's Danielle?"

"Me," Dani said, sarcastically.

Danny grinned sheepishly. "Uh, my clone?"

"WHAT?!"

"You were cloned and didn't tell us!" Maddie yelled.

Danny winced and covered his ears. Dani, Jack, and Jazz did the same thing.

"Hey! Super hearing is very sensitive!" Dani said. "And I left to travel the world! You wouldn't have believed him if he told you."

Jack and Maddie glanced at each other. That was true.

"Well, you're still a Fenton and I won't have a Fenton just roaming the streets," Jack stated, proudly.

Danny and Danielle blinked.

"Does that mean what I think it does?" Danielle asked.

Maddie nodded. "Welcome to the Fenton family, Danielle."
