Hey guys! Another story idea, this one being about…(drum roll)…what if Danny wasn't the only Fenton to get ghost powers from the portal? What if they ALL did? Read and find out! Disclaimer: I am not Butch Hartman. Therefore, I own nothing except the idea. (Also, Jack isn't fat in this fic, he's ridiculously well-built)

The Halfa Family

Chapter 1

"DANNY! JAZZ! COME DOWN TO THE LAB!" Jack Fenton bellowed up the stairs.

A raven-haired teen and his redheaded sister sighed. They looked at each other and started talking in perfect sync.

"You first."

"No, you."

"Rock, paper, scissors?"

"Best two out of three?"

"Deal."

They each held up a fist and pounded into their open palm three times. Danny came up with rock, and Jazz had scissors. A frown came across her face as they prepared for round 2.

Danny won with paper, and Jazz hung her head in defeat before dragging her feet towards the basement door. She didn't even get halfway there before she was met with a wall of orange. "There you are! Come on down, your mother and I want to show you something!" Jack exclaimed, before tossing Jazz over his massive shoulder like a sack of potatoes and heading down to the lab.

Danny just chuckled at his father's antics and followed the massive, jumpsuit-clad man down to the basement lab.

What he didn't expect was the massive hole in the wall.

Well, it wasn't so much a hole, more like a tunnel, with the end capped off. There was an artist's easel propped next to it with what looked like a blueprint on it. In big, bold letters across the top were the words "Ghost Portal". Danny groaned. It was bad enough they lived in Amity Park, the most haunted city in America, but he also had to be the son of the most obsessive ghost hunters in the world.

A woman in a blue jumpsuit stood off to the side, running a few last-minute calculations. She looked up as the three approached, a wide grin plastered on her face.

"Ah, there you are! Come, come, it's finally ready for testing! The calculations look good, and everything seems to be in order," she said, not bothering to hide the obvious excitement in her voice.

"Well then let's fire this baby up, Maddie!" Jack yelled, and he grabbed two plugs. With a smirk at his family, he plugged in the portal.

There were a few greenish sparks, then nothing.

Jack's face fell. "I…I was so sure…" he said dejectedly. He literally looked like his dreams had shattered in front of him.

Danny couldn't bear to see his father like this. "Hey, maybe something's up with the inside of the portal! I could go in and see," he said quickly, and his father's face lit up like a Christmas tree.

"That's a great idea, Danny-boy! If all four of us go in, we can cover more ground!" he exclaimed, before turning around and grabbing two HAZMAT suits from hooks on the wall. He turned around, his normally cheery face turning deadly serious.

"Now, kids, I understand that you don't like wearing these. I understand that they aren't "the latest fashion", or, as Danny puts it, "even remotely cool". But this time, there is no room for arguments. We're dealing with high-voltage stuff here, and I want you to be protected," he said, giving them a surprisingly stern glare.

Both kids gulped, nodded, and put on the suits.

All four Fentons then went into the portal to figure out what was wrong.

-TIMESKIP: 10 minutes later-

Jack threw his hands up in defeat. "I thought for sure there was something here!" he yelled exasperatedly. Maddie went to console him as Jazz sat on the floor of the portal. Danny shook his head and leaned against the wall.

Click.

Everyone turned at the sound, and Danny moved his arm to see what caused it.

A big, green button. Labeled "ON".

They heard the whine of energy as the portal started up, and they looked at each other as they shared the same thought.

"Oh, shit."

Suddenly, the portal blasted to life, and everything went green.

After what felt like hours, the four Fentons finally staggered out of the portal, but they weren't the same as they were when they went in.

Jack's raven hair had turned silver, going down in a ponytail to his shoulder blades. His jumpsuit was gone, replaced by a black, skin-tight tunic, a white leather belt, and white jeans and black combat boots. On his massive hands were white fingerless gloves, with studs on the knuckles. His eyes had changed from their usual baby blue to a burning orange, almost like looking at fire, and he found fangs where his canines used to be.

Maddie now sported jet-black hair, which tumbled down her back free from any restraint. Her jumpsuit remained, though it was now as black as her hair. Her eyes were now sky-blue.

Jazz's hair had turned a deep red, and if one looked closely, they could see flickers of flame passing through the locks. Her jumpsuit was gone as well, replaced by a white cut-off shirt that exposed her midriff, with black pants and white combat boots. She had fingerless gloves, although they were black instead of white. Her eyes were a deeper red than her hair.

Danny's appearance had changed the most.

His black hair was now white as snow, and his eyes were a poisonous neon green. He had fangs as well, just like his father. His jumpsuit was replaced by a black Assassins' outfit, albeit slightly modernized*. He had black fingerless gloves on, with black pants and boots. He had a white belt around his waist, like his dad.

They looked at each other, then sank to the floor, unconscious.

While they lay on the floor, something happened.

A white ring appeared around Danny's waist, then split. One ring traveled up toward his head, the other down to his feet. As the rings passed over him, he was changed back to his original appearance, minus the HAZMAT suit.

The same phenomenon occurred with the rest of the Fentons, although the rings were different colors.

Jazz had red rings, while Maddie's were blue, and Jack's were pitch-black.

-TIMESKIP: 15 minutes later-

Danny awoke with a start. He sat up, groaning and clutching his head, as he tried to remember what happened. All he remembered was accidentally pushing a button, then green, then...nothing.

Danny's groan caused the other Fentons to stir and regain consciousness.

Jack jumped up, looking around the room warily before his eyes settled on the swirling green vortex of the ghost portal. His jaw dropped, then his face lit up with unrestrained joy. Danny smiled at his father's antics, but was quickly rendered shocked as a black ring appeared around his father's waist and split, one going up, the other down.

He stared, slack-jawed, at his father as his entire appearance changed before his eyes.

Jack caught Danny's eye. "What? Is there something on my face?" he asked, his voice echoing a bit. Danny just grabbed a shiny piece of metal and held it up.

Jack gaped as he took in his reflection. He then started to panic. Was he a ghost? Did he die? Was he evil? He was even further startled when a black ring appeared around his waist and split, changing him back to his original appearance, jumpsuit and all.

Jack suddenly gained a thoughtful expression. He noticed Maddie regaining consciousness and ran over to her, helping her up.

"Maddie, I have something I want to run by you. Promise not to think I'm crazy?" he said. Maddie raised an eyebrow but nodded. Jack took a deep breath and blurted out his hypothesis, but he ended up tripping over his words.

Maddie looked at him with slightly raised eyebrows. "From what you've just told me," she said slowly, "am I correct to assume that since we were electrocuted and bombarded with ectoplasmic energy simultaneously, we've entered into a half-dead state?" Jack nodded, and Maddie shook her head. "Jack, that's impossible," she said gently. Jack huffed and closed his eyes in concentration. He felt the rings pass over him and he opened his eyes to find a gaping Fenton family.

Jazz was the first to recover. "Dad?" she asked hesitantly. Jack smiled. "It's me, Jazzypants," he said. He let the rings wash over him again and he was back in his original appearance.

He thought of something. "Guys, I know this might sound crazy, but just g with me on this. I want you to think about changing. Like, everything about you. If my hypothesis is correct, I think we've been turned into half-ghosts," he said slowly.

Everyone closed their eyes and concentrated. Jack watched, dumbfounded, as colored rings of light changed his entire family's appearance before his very eyes.

Jazz's rings were red, Danny's white, and Maddie's deep blue.

He felt a smile work its way onto his face before he transformed.

On a whim, he jumped into the air and thought of hovering in place.

When he looked down, he saw that he was indeed hovering a few feet off the ground. He thought about descending and he did, landing lightly on the balls of his feet.

Danny concentrated on forming a ball of energy in his hand, and a green ball of ectoplasm formed, floating about an inch above his open palm.

Maddie concentrated on becoming invisible and disappeared, only to reappear seconds later with a satisfied smile.

Jazz was the most outgoing, concentrating on being on the opposite side of the lab, before she was enveloped in a whirl of fire and disappeared, only to reappear in a burst of fire on the opposite side of the lab.

Suddenly, a colored mist escaped everyone's mouth. Jack's was yellow, Maddie's was violet, Jazz's was red, and Danny's was blue. They all looked at each other in confusion when a scythe-wielding ghost with blue skin and red eyes appeared in front of them, a staff with a clock on top in his other hand. He smiled at the family as they jumped and settled into fighting stances.

"Peace, Fenton family. I mean you no harm. I am Clockwork, master of time. I'm simply here to explain what's happened," he said in a calming voice.

Clockwork wasted no time in informing the Fentons of their situation.

"As Jack hypothesized earlier, you four are indeed half-ghost. The technical term we have for you is "halfa". As far as I know, and I know everything, there is only one other halfa in existence in this timeline. I believe you know him as Vladimir Masters." Cue looks of shock from the Fentons.

Clockwork smiled. "First things first, though, we need to figure out what cores you each have. I may be omnipotent, but correctly judging a ghost's core is impossible for most everyone, and it is barely hit-or-miss for me. I need you to transform, then tell me the sensation you have as the rings pass over you." The Fentons transformed as one.

Jack spoke up first. "It felt like my entire body fell asleep. Kind of tingly," he said.

Maddie was next. "I felt cool, but not cold. Like a springtime breeze."

Next up, Jazz. "I felt hot, like I stepped into a sauna"

Last, Danny. "I felt cold, like I was stuck in the North Pole."

Clockwork smiled again. "Jack, you have a lightning core. Maddie, yours is air. Jazz, you have fire. And Danny, your core is ice," he explained, then he stuck out his hand. It glowed purple, and a violet aura briefly surrounded the Fentons, before disappearing. "I have unlocked your basic elemental powers, but it is up to you to seek out a tutor for training. You will also find that many other abilities will manifest themselves in due time," he explained. He then formed a blue portal behind him. "You may or may not see me again, but I wish you the best. Until we meet again," he said, before he disappeared into the portal and it vanished.

The Fentons let out a collective sigh and transformed back into their human selves.

Jack looked at his family and wrapped them in a bear hug. "I have the most badass family ever," he said happily.

"So what do we do now?" interjected Danny. "How do we use our powers?" Jack looked thoughtful. "I think we should train first, then we could protect the town from the ghosts that are likely to come out of this portal," he said, jerking a thumb over his shoulder at said portal.

The rest of the family nodded, then Jazz spoke up. "Wait! If we're going to be superheroes, we need secret identities, right?" she said, and everyone thought about that. It was a sound argument. Jack nodded. "Great idea, Jazz. My ghost form will be known as Shade from now on," he said proudly.

Maddie went next. "I'll be Specter," she said confidently.

"I'll be Flare," Jazz said with pride.

Danny took a while to decide. He finally decided, and chuckled a bit at the similarity to his last name.

"And I'll be Phantom."

Well guys, I hope you enjoyed! Feel free to leave a review, no flames please!
