Okay, for context, I'm going to be basing Amity Park in Illinois. Come after me, if you want, but I feel it belongs there.

As always, I do not own Danny Phantom or Harry Potter. Nor am I the proud creator of the idea that Harry Potter and Danny Fenton are brothers.

Line Break.

"Box Ghost, give it back! It's not even mine; it's Jazz's!"

As Harry stood on the unfamiliar street with Hagrid, he couldn't have imagined the bizarre scene that was about to unfold before him. Cackling echoed all around Harry as a blue-tinted figure emerged from below both him and Hagrid, holding tightly to a thin box before taking off down the street. But not before pausing then yelling, "BEWARE!" into Harry's face as a door flew open and a boy emerged, putting on a jacket as he jumped down the steps and ran off down the street. Harry blinked in confusion, wondering if he had imagined the strange blue figure. Before he could process what he had seen, chaos had erupted around him. Just as Harry thought the situation couldn't get any stranger, more characters joined this peculiar chase. Two more preteens emerged not five minutes later; the only girl of the group, dressed in gothic attire with purple-streaked hair, could be heard shouting as she ran after her friend, "DANNY!"

"Hagrid, where are we?" The street looked ordinary as Harry found himself admiring the houses before them.

"Amity Park, Harry." Hagrid looked down at Harry, "We're in the Americas to pick up Jasmine Fenton and her brother, Daniel."

The other boy, with messy brown hair and glasses, turned back to Harry and Hagrid with a sheepish grin before darting off after the blue-tinted figure. Harry watched the trio disappear down the street, their shouts fading into the distance. He turned to Hagrid, hoping for an explanation, but the giant seemed equally perplexed as he looked down at Harry with a raised eyebrow before looking up at the house the three had run from. Sounds of something happening down the street could be heard as Hagrid laid a hand on Harry's shoulder and guided him onto the sidewalk leading to the house.

As they approached the house, Harry's eyes were drawn to its unusual features, which seemed to perfectly match the odd events he'd just witnessed. The most prominent feature that Harry would always remember was the structure perched on the roof of an otherwise ordinary-looking house. The only other thing that stood out was the massive sign proclaiming it as 'Fentonworks' with an obnoxiously large arrow pointing down to the open door as a teenager of about thirteen came running out of the door and stopped as Hagrid approached, looked at him closely, and smiled in greeting before turning to Harry with a curious expression. Turning back to the house, she shouted, "Mom, Dad! Hagrid's here. I'm gonna look for Danny!" The girl hurried off, leaving Harry feeling slightly bewildered as he glanced up at the strange structure on the roof. Harry's bewilderment grew as he realised that the strange occurrences seemed perfectly normal to the inhabitants of this house. He couldn't help but wonder what kind of place 'Fentonworks' was as he followed Hagrid towards the open door.

The girl's departure left Harry and Hagrid standing awkwardly on the doorstep, their eyes following her retreating figure until she'd disappeared around the corner. An uncomfortable silence settled between them, broken only by the distant chirping of birds and the rustle of leaves in a gentle breeze. Harry shifted his weight from one foot to the other, unsure of how to proceed or what to expect next. He glanced up at Hagrid, who seemed equally uncertain, his massive frame hunched slightly as if trying to make himself less imposing in the unfamiliar surroundings.

The sound of footsteps approaching from within the house broke the atmosphere a few moments later. A creak swung the door wide, revealing two adults whose animated talk instantly filled the environment. As they embraced Hagrid, they clapped his huge hands in theirs and gave him a pat on the back, sounding as though they were seeing an old friend again. Their voices were a mixture of excitement and interest.

Harry's mind strained to comprehend the surprising sight in front of him, and his eyes widened as he took in their odd appearance. The man wore a bright orange jumpsuit that seemed to sparkle in the afternoon sun. He was tall, sure, but he also had a girth to his body that told of unseen strength, with a mop of unkempt black and silver hair. Many pockets swelled with a variety of tools and devices, the functions of which Harry could not understand.

The woman, on the other hand, was wearing a blue hazmat suit that exposed her face and covered her entire body. She looked like a scientist prepared for a risky experiment, with her auburn hair partially concealed by a hood and a pair of crimson goggles resting on her head.

As Harry observed the peculiar couple, he couldn't help but wonder about the nature of their relationship with Hagrid and what kind of household produced such uniquely dressed individuals. The contrast between their outlandish attire and the ordinary suburban setting only added to the surreal nature of the situation, leaving Harry feeling as though he had stepped into a world far removed from what he knew.

"Hagrid." The man almost shouted as they recognised the giant and came outside to greet him, "You just missed Dann-o and Jazz."

"I can imagine they had somewhere important to be, Jack."

"No," the woman answered, smiling kindly, "but the Box Ghost got out again and stole Jazz's wand box. I have no idea why they all had to run out."

"Box Ghost?" Harry asked; he looked just as confused as Hagrid was as a garbage bin crashed behind them all, startling everyone into turning as a young boy, pure white hair falling into his eyes, picked himself off the floor, growled slightly, and sped off. Jack looked ready to go after the kid as his hands twitched to his hips.

"Oh, it's what the kids call him."

"Jack, I don't think Hagrid and, what was your name, dear?" The woman asked, looking to Harry curiously. Hagrid laid a hand on Harry's shoulder, causing his knees to buckle slightly as he answered for the 11-year-old.

"Maddie, meet Harry Potter. Harry, this is Madeline and Jack Fenton." Hagrid smiled as Maddie looked at Harry and replied softly, "You look just like Danny, except the eyes. Come in; you must be tired after your trip. Jack, we can catch Phantom when the kids have gone."

"But Mads." Jack whined, looking longingly down the street. Maddie gave him a pointed look before turning back to Harry, ushering their guests inside their cosy home. "Don't worry, we'll catch up on Phantom later," she assured Jack with a warm smile. As they entered the house, Harry couldn't help but feel a sense of warmth and comfort wash over him. The Fentons were kind and welcoming, making him feel at ease in their home. Maddie led them to the living room, where a fire crackled in the fireplace and the smell of cookies filled the air.

It felt like hours before the door opened once more and voices filled the air, laughing at a joke said by the dark-haired boy holding the door open. From the view of the sofa where Harry sat, he observed as they all entered, the gothic-looking girl hobbling in with one shoe in her hands, poised as if it had just been thrown. Her face, underlying with mirth, was set in a scowl that she was directing at the boy who rubbed his head in exasperation as he entered last, muttering something under his breath as he tried to make sense of the chaos that had just entered the room. His messy hair stuck out in all directions, a mix of frustration and amusement evident in his expression when the oldest of the quartet, the red-haired girl from earlier, now carrying the box that had caused the ruckus, entered. She held onto it tightly while she closed the door and then ran up the stairs. The others followed closely behind her, their footsteps echoing on the wooden staircase as he tried to catch up. The scowl on the girl's face softened slightly as she glanced back at them, a hint of a smile playing at the corners of her mouth before Maddie called out, "Danny, stay here, please."

"Mom, I gotta finish packing."

"Okay, but don't take too long, Danny. Hagrid is here to take you and Jazz back to England." Danny flashed a smile before he rushed upstairs to finish the task he'd started that morning. A moment later, a bedroom door was closing as Harry turned back to the adults as they began talking about nothing in particular, fidgeting slightly.

"Excuse me, do you know where the toilet is?" Harry asked, feeling a little awkward interrupting the conversation. Maddie paused in the conversation as she heard Harry speak up, gave a gentle smile, and replied, "Just up the stairs, second door on the left."

Thanking her, Harry followed the directions upstairs, the two men beginning the conversation again. Similar chatter could be heard coming from a closed door as Harry got to the top of the stairs and paused as he heard, "(I)'m just not sure if I can stay away that long."

"Danny," a girl's voice answered the first, "you could always tell them the truth or that you have to go away for a while."

Harry gulped slightly, unintentionally eavesdropping on what appeared to be an intense conversation as the voice called Danny scoffed, "You know they want to rip me apart molecule by molecule, Sam. I show up here as Phantom; I may as well be offering myself up for dissect-."

"They've mellowed out a bit." A new voice interjected, "The accident was, what, three years ago when we were nine? You've had plenty of time to show them you're good. That there is such a thing as a good ghost."

"I guess. Look, I gotta put Boxy back. Could you pack those letters in my satchel, Tuck? I don't want to lose them." Harry looked like a deer in headlights as the door began to open, only to pause as Harry hurriedly opened a random door and stepped inside, only to pause when someone let out a sigh and spoke, "Danny, for the last time, I'm not allowed to use magic outside of school. Thank you for getting my wand back, but could you go back to packing your bags?"

Harry turned as he realised that he'd accidentally chosen the wrong room, turning to see the older teenager sitting on a neatly made bed, stroking a snowy owl perched on her shoulder. Up close, the girl wore a plain black t-shirt and blue jeans. Her long hair was held back with a headband as she stared at him with a mix of curiosity and annoyance before it was replaced fully with amusement as Harry stammered out an apology. Standing, she coaxed the owl into a waiting cage and closed the door before she approached him, looked him over, and said, "You're definitely not my little brother. He wouldn't be staring at Tala like she's going to bite him." Harry chuckled nervously, relieved by her response to his unintentional intrusion.

"Sorry, I…I was looking for the bathroom." Harry stammered out, nervously watching as the girl picked up the cage, grabbed the handle of a large trunk, and cocked her head at the British boy in front of her.

"Next door on the left." She said after a minute, Harry opening the door as she approached and allowed her to exit, exiting after her and heading in the opposite direction down the hallway. As she got to the top of the stairs, she paused and called over to him, "By the way, my name's Jazz. Jazz Fenton."

"Harry. Harry Potter. Nice to meet you, Jazz," Harry replied with a smile before continuing on his way, feeling a bit embarrassed but grateful for her help. Jazz nodded back and disappeared down the stairs, leaving Harry to navigate the unfamiliar house on his own.

Line break.

Danny soon came down, backpack ready in his hand, as he spoke with Sam and Tucker, leaving soon after they'd made sure that his room was free of any inventions or ghostly anomalies that may have been left behind. Danny thanked them before they headed downstairs to find Jazz engaged in conversation with a boy who looked just like Danny and was cautiously trying to pet Tala and getting nipped at for his efforts. A tall man, almost a giant, was watching the two curiously as Danny's parents spoke to one another, Maddie folding and refolding Danny's baby blanket while she spoke to the man and Jack beside her. A calligraphic 'D' embroidered in a corner stood out as Maddie finally got the blanket neat and laid it on her lap before she spotted Danny, Sam, and Tucker and smiled, "Kids, come on down."

Danny, Sam, and Tucker made their way down the stairs, with Tala hooting softly in greeting. The boy who resembled Danny looked up in surprise as the trio approached, his eyes widening in recognition before it was gone in a second, Jazz watching as the two looked then stared at each other in shock.

"Danny," his mother began, capturing his attention, "I'd like you to meet Rubeus Hagrid, Keeper of Keys and Grounds at Hogwarts, and Harry Potter, one of your classmates in the coming year."

I know this waffles on a bit, but I wanted to get it out. I also had to use Quillbot to help with a few paragraphs. But at least the boys have met. I'm still going with my original plan though.
