Yes, it's happened, my attempts at writing anything larger than one chapter for a much larger story have reached that uncomfortable point where no matter how hard I try, I cannot keep only that story in my head. Therefore in an effort to try and ease my poor stressed brain, I am making one of those Plot Bunny stores, this one being specifically for Harry Potter. At the end of each one I will detail any changes or restrictions I have in my mind, in other words, I will try and end each chapter for these with a challenge, in which you can use the chapter I have written as a starting point or as inspiration. So without further delay, here is the first of the chapters.

"French Speech"
'Thoughts (No differentiating between languages)'

"Harry Potter!" Cried Dumbledore, reading off the name that had just been drawn as a fourth contender for the Tri-Wizard Tournament.

'This cannot be happening.' Thought a glasses wearing teen sitting at the Gryffindor table.

"Harry Potter!" Cried Dumbledore once more, this time looking at the target of his cries as opposed to the paper within his palm.

"No no no, this is not good, this isn't happening." Said teen began muttering.

"Go on Harry, go." Encouraged Hermoine Granger, shoving her friend towards the Headmaster at the podium in front of the room.

The teen, identified as Harry Potter, began slowly walking towards the front, muttering "This isn't happening, I'm so dead." Over and over again. Upon reaching the cup and where the Headmaster stood, twinkling eyes showing mirth at the stunned reactions of the hall, Harry suddenly halted, turning towards Dumbledore.

"Professor, might I, might I please, PLEASE, see that piece of paper you have there?" Enquired Harry, holding out his hand towards the Headmaster.

"Of course dear boy, here you go, your entry, bearing your name and nominating you, Harry James Potter, as contender number four for the Tri-Wizard tournament." Replied Dumbledore, the twinkling in his eyes reaching levels that genuinely made some people worry for the old wizard's health.

"Out of curiosity, what would happen, if uhh, if the named contender wasn't actually HERE, per se?" questioned Harry, his voice beginning to sound frightful and weary.

"Well, the magic of the Goblet would have summoned them from wherever they are, bringing them before it momentarily!" Shouted Dumbledore, the large grin on his face unnerving the young teen.

At the exact moment he finished that announcement, for all of the hall, silent as it was, to hear, the doors leading to the Entrance Hall were blasted open, and a teen appeared, having been deposited by a great ball of fire akin to the smaller ones that had released the competitors names from the Goblet.

Everyone in the hall observed the teen, the flashes of recognition and mild fear in the French student's eyes not being missed by the elderly wizard, as he, like the rest of the hall, took in the new arrival. The teen had on faded black denim jeans, each side having a series of chains, three on the left, four on the right, connecting from the bottom of the sides to the waist of the pants, the pitch black combat boots clearly visible from underneath the ends of the jeans. The teen's upper body was covered by a denim jacket, it too was adorned with chains, four on the left and three on the right this time.

The boy's, for the teen in question was unmistakably male, hand's bore a pentagram tattoo open the backs of each, these tattoos caused sparks of recognition to appear in the eyes of several people in the hall, all being people who kept track of the European Amateur Duelling League. The boy's hood was being slowly lowered by these hands, and the face underneath the hood shocked Dumbledore more than any he had seen in a long time. The aristocratic features, the black bedhead like hair that spoke of numerous attempts to be tamed, and the frightening eyes, glowing in rage with the colour that many of the adults there realized as the emerald of the Killing Curse. Yes, Dumbledore was indeed surprised, because standing before him was a carbon copy, minus the tattoos, of the boy standing in front of him, who at the very moment let out a frightened squeak, drawing the old man's attention back to him.

As the new arrivals eyes landed upon his copy standing in front of the cup, a guttural growl erupted from his throat.

"WHY, have I been summoned HERE, from my comfy room in Beauxbatons, my dear, little, sssissster!" Shouted the teen, slightly accented with French and ending with an unmistakeable hiss, the rage and mockery was evident in his voice as he yelled, his eyes glaring like knives upon the frightened boy before him.

As if in response to his declaration, the teen before Dumbledore begin to change, a shifting he recognized quickly as the same belonging to a student who had graduated 2 years prior, as being the shifting of a Metamorphagus. Dumbledore was quite surprised, as were many people in the hall, when the carbon copy of James Potter with Lily Potter nee Evans eyes, shifted into a carbon copy of the exact opposite, Lily Potter nee Evans, with James Potters eyes and glasses.

"I'm sorry I'm sorry I didn't do anything I swear Harry don't be mad!" Screamed the girl, fear being a very obvious emotion upon her face, completely oblivious to the reaction of the British and Bulgarian student's reaction to the teen before them being addressed as Harry.

"You never listened did you Charlotte, I said time and time again, to leave this school but no, you INSISTED that the next year wouldn't be so bad, that it would be better, that I would not have a snowy white owl bringing me another BLOODY LETTER ABOUT YOU BEING IN TROUBLE!" Roared Harry, completely oblivious to the scene he was causing.

"ENOUGH!" Yelled Dumbledore, attempting to grab the attention of everyone, "Would someone please inform me as to what is going on?"

"That is simple, I, Harry Potter, have been attending Beauxbatons for the past four years, whereas my fraternal twin sister over there, INSISTED that she be allowed to attend the school our parent's went to, and, rather than causing a scene, she simply used her Metamorphagus powers to attend in my place, considering that the school had me down and paid to attend, but not Charlotte, a slight oversight on our parent's parts in their bid to keep us safe." Deadpanned Harry, completely ignoring the reactions this elicited from everyone, Dumbledore noting a distinct lack of surprise coming from the bushy haired girl just behind the rather angry teen.

"Well then, I ahh, I do believe we can make arrangements, for uh, this, change, if, MS Potter, would like to continue attending, I am sure we can change the records to ahh, reflect, the uhh, difference, between the two of you, of course." Said the rather stern looking but flustered Scottish Witch as she came around to try and calm the poor hyperventilating redhead down.

"Hmmf, I take it I still have to participate in this bloody Tournament?" Asked the teen, his emerald gaze piercing into the eyes of the rather exuberant looking Ministry official, who looked as if he had struck gold with this development.

"Why yes, yes you will! If you will just come with me, I'm sure Madame Maxine will be more than happy to send for your things." Replied the jolly man, practically bouncing in place as he slowly walked over to the entrance for the antechamber the previous champions had disappeared into.

"Why don't you come with me Ms Potter, I can take care of all the necessary paperwork and movements required to have you placed with the girls in your year, and of course to actually be registered as you, as opposed to remaining as your brother." Said the Scottish woman, slowly dragging the now calm girl out of the hall.

"We will speak later sister." Muttered Harry, just loud enough for Charlotte to hear as she passed him by.

It went without saying that Halloween Night never exactly went well for the Potters, a family curse that appeared to be apparent in BOTH of the siblings.

I know I know, not the largest of bunnies snagged here, but then again, it isn't exactly my intention to expend all my effort onto the little blighters. No, I am aiming, amidst the sea of new games I have because of the sale, to bit by bit work up a few chapters for a story I DO have in the making, so as when I release it I will not be struggling so hard against my rather uncooperative muse.

Anyway, onto the details of what I would consider necessary for anyone attempting this as a challenge.

Summary: When Harry's name came out of the Goblet of Fire, nobody was expecting for the Goblet to have summoned a different Potter, nor for the one they knew to suddenly be a girl!

Requirements:

Years 1 and 2, for the most part, happened the way they canonically did, only minor changes are allowed to the EVENTS that happened.

NEITHER POTTER SIBLING GREW UP AT THE DURSLEY'S! At most, Harry spent a couple of days there before whoever was looking after Charlotte took him from the all too willing Dursleys.

The Potter that attended Hogwarts for said years is to secretly be a girl, a Metamorphagus capable of shifting forms, unlike Nymphadora, these changes are stable, but only between the two forms of Harry and FemHarry, all other changes not being capable of being held for more than a few minutes.

Actual Harry attended either Beauxbatons or Durmstrang, and is well known by the attending students. It is important to note that the schools are both open to all, not just boys or girls as some stories portray. OC characters for these schools are entirely up to you.

Harry and FemHarry ARE NOT allowed to end up with ANY Weasley, I don't hate the Weasley's I've just never liked the Weasley's for pairings. To be clear, this means no Harry/Ginny, and no FemHarry/Ron or George or Fred or Percy or Charlie or Bill.

Also, yes, as obvious above, Het pairings please, I don't have a problem if the side character pairings are slash, just not the two main characters.

Optional:

Manipulative Dumbledore shocked that his chess board is in disarray from the revelation that the Harry he has been manipulating is not in fact the Chosen One, and that Harry HATES him for what has happened to his sister, ie Dumbledore's manipulations, under his watch.

Whatever explanation you want for why the hell nobody knows about Charlotte.

As suggested above, alternate year 3's are allowed, simply because one potential reason this was able to happen could be that Sirius was never foolish enough to go after Pettigrew, potentially because of baby Charlotte, therefore was never arrested and was able to prove his innocence, as well as hide the twins.

If it suits your style, loaded Potter's.

Have a pleasant time, and thank you for viewing what is most likely going to be a potentially large depository for plot bunnies. This is after all the only humane way to get rid of them, and last time I tried to light one of them on fire my muse wouldn't speak to me for a week.

Thank you for your time.
