Anyway, here to the oneshot. Same crossover as TTH but it is what happened at Hogwarts i mentioned in chapter six.

Anyway lets get this over with.

Disclaimer: nope, zip, nada, tibota, nenio. I do not own Danny Phantom or Harry Potter, no matter how much I wanna I just aint rich enough.

Peeves

Peeves raced down the Charms corridor, cackling his head off. He had just caught another student of Hogwarts in one of his pranks. A kid who went by the name of Seamus Finnigan of Gryffindor House was the victim. As he flew, he noticed the teacher known as 'professor Mcgonagall' come running as fast as her pityful human legs would allow, some other teachers in tow and right behind her. What he didnt notice was that the four Hogwarts house ghost's come through the wall ahead of him. He noticed them as he saw movement just behind had brought someone else with them. A someone who had silvery hair and was wearing a kind of Muggle jumpsuit that was black with white hints on the belt, boots, glove and collar. There was only one ghost that Peeves the poltergeist knew of that had that exact same description: Phantom. Danny Phantom had come to Hogwarts school of Witchcraft and Wizardry, all the way from America, no doubt.

Deciding to not take any chances with the five ghosts in front of him and getting closer with every second, Peeves darted towards them and forced them to scatter as he ploughed through them, Phantom falling through the wall in surprise. As soon as he was through them, he thought he heard a voice saying "Pedicabo!". Who had said that, Peeves had very good feeling.

Looking behind as him as he went around the corner, he was surprised to see that the five ghosts he had just ploughed through were actually chasing him along with the Professors on the ground. Looking ahead of him again, Peeves saw a suit of armour just dead ahead of him. If he could just get to it then he would be scot free of the pesky ghosts and humans who were determined to ruin his fun. And all for the sake of the safety of the students and faculy alike. Getting inside his temporary hiding place, Peeves sat back and tried not to make a sound as he listened for the tell tale signs of the teachers running past the suit of armour. As he listened, he wondered why the ghost's had brought Phantom with them and how the heck they had managed to persuade him to come along.

Nearly Headless Nick

A few days before

Nearly Headless Nick was floating down the hall, when a very colorful blur zoomed past him, cackling madly. Peeves again, probably running away from his latest prank. And sure enough, not a minute later, there was a scream and a thud as the poor soul was either thrown to the floor or hanging off the ceiling by his shoelaces. Sighing as he continued down the hallway, he saw the Golden Trio and a couple more of their friends trying to get one of their housemates down from the ceiling.

"Hello, Nick." Harry Potter called to him as he passed. Hermione also looked at him, her bushy hair sticking out even further, and waved before focusing her attention back onto their fellow Gryffindor, Neville Longbottom. Floating ever so slightly down to them, Nick was amazed that Seamus Finnigan and Ronald Weasley were also helping get Neville down.

"Good day to you, Harry, Hermione, Ronald, Seamus and Neville. Peeves again?" He greeted, The five nodding at his end question. Sighing, he floated off, muttering "It is official. We need outside help. But who to ask for?". As he floated off in the direction of the Entrance hall, he thought he saw Hermione Granger looking puzzled at his words, before she turned back and shrieked as Neville came crashing down from the ceiling right beside her.

As he floated down to the Entrance hallway, he caught a glimpse of the Bloody Baron who was trying to catch Peeves as he blew raspberries and hopped higher into the air as Baron was wavng his chain around, in the hopes of capturing the poltergiest.

"BARON!" He called to the ghost of Sytherin house, who upon hearing his call, gave up on Peeves who blew one last raspberry and flew off cackling madly, and came over. As soon as he came to the Gryffindor ghost, said ghost went off in search of the other two house ghost's: the Fat Friar and the Grey Lady. Together the four of them made the ghostly council of Hogwarts, Not that any of the students, past, present or indeed future, knew that. Nor did they need to.
After getting the two missing ghost's, the four of them set up a meeting for later that evening.

Later as he was waiting for the others to join him, he pondered on how to address the issue. It was just too much work for the Bloody Baron to handle alone anymore.

'We need outside help. And we need it fast. But who to go to?' He thought to himself. As he paced the dungeon, another ghost by the name of Moaning Myrtle came up to him. As she was the only Hogwarts ghost who went outside, if sometimes unintentionally, she might possibly know who to call. As she came up to him, he could see that she was trying her best to look confident and not bolt away to her bathroom as was her wont. Stopping his pacing, Nick looked at her as she tried to say what was on her mind.

"What is it, Myrtle? You can say what you wanna say to me." He said going uo to the frightened ghost girl. Taking a deep breathe, she mumbled something incoherent and quiet. Asking her to repeat it again, she looked down and whispered just loud enough for him to catch.

"I know who to call." were the words she whispered. Just as he was about to ask what she meant, the others joined them and the meeting began but this time it wasnt just four ghosts attending, it was four and an informant.

"We all know what this meeting is about." Nick began saying, "Peeves has gotten out of control and something has to be done about it."

To his surprise, the other ghost's agreed, including the poor bathroom ghost. The Baron nodded, but that was to be expected, whilst the other three agreed vocally.

"But how do we do that? Peeves doesnt listen to anything we say and he went through Elizabeth earlier this week. It scared the poor girl. Not to mention Minerva was furious when she saw the Longbottom kid strung up like a piece of meat." The Fat Friar said, with the others nodding at his words. The Grey Lady looked at Myrtle in confusion as to why she was floating there at the back.

"Luckily there might be someone who CAN help us." Nick said as he looked at the shy girl floating and listening in. That caught the attention of the others straight away. The Baron appearing to sag with the responsibility of what he had to do. At the questioning glances he recieved, Nick sighed and beckoned Moaning Myrtle over to join them.

"Myrtle here knows who might be able to help us." The girl in question seemed to shrink in on herself as the adults looked at her in surprise. Managing to grin a little, she muttered a single word. Just one word.

"Speak up child. Tell us who this person is." the Baron told her. Looking up into the faces Myrtle repeated the word louder. It was the one word that every ghost in Hogwarts knew.

"Phantom." She said, to everyones shock and disbelief. Even Nick was surprised at the name. Phantom wasnt easy to get ahold of, much less talk to. He haunted an American town for Merlins sake. Also rumour had it that he belonged to neither the living OR the dead worlds, but stuck somewhere in the middle. But if Myrtle thought that he could help then maybe, just maybe they could try and contact him. It wouldnt be easy either.

Even the Baron was having a hard time processing this as he chastised the girl for even thinking of bringing up Phantom's name. Bursting into tears, Myrtle fled the dungeon and flew off in the direction of her toilet, her cries echoing in the hallways. Turning to the ghost of Slytherin house, the Hufflepuff ghost demanded why he had been so hard on the young ghost. He had never felt so angered in all his after life.

"Because how are we going to get ahold of Phantom. He might not even know of our world. He's a muggle ghost for crying out loud!" The Baron cried. Nearly-Headless Nick however looked thoughtful.

"Well, I think it's a great idea. If we can prove to him that we mean him and his city no harm, that is" He said, to the Baron's disbelief. The chained ghost couldnt help but splutter and try to protest. Holding up a hand, Helena agreed, as did the Fat Friar.

"Then its settled then. We'll try and get Phantom to sort out Peeves." Nick said, ending the meeting. After the Baron and Friar had gone, Helena asked the one question that came into Nick's mind: How to appeal to Phantom that they needed his help. Shrugging, he escorted her out of the dungeon.
The next day as Peeves was trashing a Charms classroom, the four ghosts went to Professor Dumbledore for permission to invite another ghost into the school. Although they didnt give the name away, they told him that this ghost might be able to help with the problematic poltergeist. Hearing this, Professor Albus Percival Wulfric Brian Dumbledore gave his permission on the condition that they presented this ghost to the teachers upon their return and they went on their way.

Arriving back in the dungeon they had held the meeting, they tried to figure out who would go talk to Phantom. After an hour of useless arguing, Nick had had enough and shouted as loud as he could

"Myself and Friar will stay behind. The Baron and Helena will go and talk to Phantom. Myrtle will be your guide the Ghost Zone. Now dont give me that. You have more chance of persauding Phantom than we do" Nick said, noting Barons face had turned from expressinless to shocked surprise. Nodding, the Baron and Grey Lady went on their way, with the others, up to Moaning Myrtles Bathroom.

On the way up to the bathroom however, Baron looked apprehensive. As he had been hard on the girl, he did not know if she would take them to the Ghost Zone and to Phantom.

'I just hope that she does. And if she does, then i will have to apologize to her.' He thought as they stopped in front of said girls bathroom. Helena went in and after five minutes she came back out with Myrtle in tow.

"Follow me." The girl said, heading down the corridor and to the right. Going down the charms corridor, they drew stares from the students and staff alike as the gasps of surprise and finger-pointing told them. Most likely, the living witches and wizards had never seen the Hogwarts four plus one all going in one direction together.

Heading to an unused classroom, Myrtle waited for the Four to catch her up, before heading inside. Inside the classroom, there was a green vortex hanging in midair. Myrtle headed straight towards it and stopped in front of it as if she sensed their hesitation.

"Come on. You want Phantom to come, dont you? Well this is the fastest way to get to his haunt." She said, whilst floating in front of the portal. Looking at his companion, The Bloody Baron nodded and floated forwards towards the girl and the vortex. The Grey Lady followed a minute after, and together the three of them plunged into the green abyss that awaited them.

And thats the first chapter done guys. It seemed a good place to end the chapter. I gotta go do my jobs now, but will get back on the story as soon as they are finished. Translation for 'pedicabo': Fuck!

Till then, Hermione
