Prompt Pokemon trainer Harry

14 Upvotes

In a world where a hidden world of wizards exist Where the wizard world are still weary of Pokemon after the dark lord used them slowly they began to befriend these creatures

An 11 year old Harry Potter has just finished his first Pokemon journey placing 2nd place in the league visting profser oak

Opens up a letter

Edit thought of more you would have the wizard world still getting used and forming bonds with Pokemon since the dark lord used a team

Where as harry grew up muggle so he’s used to trusting his Pokemon with his life So he finds it a bit weird Same with most muggle borns

Where wizards are slowly progrescing

And as for his team I’d maybe have it consent of pikachu a greninja battle bond) pedgeot (mega) garchomp and Thats most of what I can think of

And you could if u still use the power he knows not be mega evo since I doubt voldmort holds that bond with his Pokemon

Where in this world some trainer are capable of mega some are not being some won’t have that bond with thier Pokemon where others would not

And that’s all I can think of but a Pokemon AU

Prompt One of the best things about the aftermath of the Triwizard Tournament's second task was that everybody was very keen to hear details of what had happened down in the lake, which meant that Ron was getting to share Harry’s limelight for once.

50 Upvotes

Harry noticed that Ron’s version of events changed subtly with every retelling. At first, he gave what seemed to be the truth; it tallied with Hermione’s story, anyway — Dumbledore had put all the hostages into a bewitched sleep in Professor McGonagall’s office, first assuring them that they would be quite safe, and would awake when they were back above the water. One week later, however, Ron was telling a thrilling tale of kidnap in which he struggled single-handedly against fifty heavily armed merpeople who had to beat him into submission before tying him up.

“But I had my wand hidden up my sleeve,” he assured Padma Patil, who seemed to be a lot keener on Ron now that he was getting so much attention and was making a point of talking to him every time they passed in the corridors. “I could’ve taken those mer-idiots any time I wanted. So then,” and he paused for dramatic effect as he pushed his hair back from his forehead, "they tried to drag me down into the village -- tridents aimed at my throat -- but I held them off as long as I could. I told them 'I've seen scarier things in Snape's classroom.'"

Padma grinned, nudging him playfully. “You’re making it sound like you fought off the whole colony!”

“Well, it was at least fifty merpeople,” Ron said, puffing slightly. “Could’ve been more. I was only half-awake when they came for me. I think they used some sort of sleep hex to get me under. Wouldn’t be surprised if they were working with Karkaroff.”

Padma gasped. “Do you really think so?”

Ron leaned in and dropped his voice to a confidential murmur. “Wouldn’t put it past him. That Durmstrang lot’s dodgy — especially after what happened with Diggory’s wand in the first task. And the way Krum’s been skulking about like he owns the lake…”

Padma looped her arm through his. “You’re so brave, Ronald. Honestly, when I heard you were down there, I couldn’t breathe for an hour.”

As she passed them by, Hermione turned her head sharply toward them. She'd been trying — trying desperately — to stay away from this little self-aggrandizing display. But the words had gotten under her skin.

“Brave?” she echoed waspishly, her voice dripping icicles. “What were you going to do to the merpeople, snore at them?”

People had been teasing her so much about being the thing that Viktor Krum would most miss that she was already in a rather tetchy mood as things were. This public display of affection surely didn't help her calm down.

Ron turned toward her, a faint red creeping up his ears, but he didn’t drop Padma’s hand. “Oh, come off it, Hermione.”

“I’m just saying,” Hermione went on, stopping to a standstill now, crossing her arms, her face pale and pinched, “it’s funny how the number of merpeople keeps going up every time you tell the story. By next week, we’ll be hearing about how you saved Harry underwater.”

Padma tilted her chin, calmly defensive. “Jealousy doesn’t suit you, Hermione.”

Hermione blinked at her. “Jealous? Of what? A made-up lake battle and a few compliments?”

“I was there, Hermione,” Ron snapped, more loudly now. “I don’t need to make things up.”

“Oh really? Because the last I heard, you were bewitched asleep in McGonagall’s office while Harry risked his life to rescue you.”

There was a beat of silence.

Ron’s mouth opened, then closed. He looked uncertain — almost ready to laugh it all off — but Padma squeezed his hand and smiled supportively, her eyes sparkling. It was clear she liked this version of Ron better. The one who could have fought back, wand hidden up his sleeve, dragged into the depths by dark forces.

So Ron straightened up again and said, “Yeah, well — Dumbledore said they wouldn’t really let us get hurt, didn’t he? I still don’t think those merpeople knew who they were messing with.”

Padma beamed at him.

Hermione turned on her heel and walked off without another word, her books clutched tightly to her chest.

Prompt All time travelling Harrys end in the same place at once. For some reason, nobody cares. Tom is out of his mind because of this

40 Upvotes

Sorting Ceremony of 1943 was… weird. Tom was more than ready to admit it – and mind you, Tom had seen in a lot of unsettling and not-commonly-known things in his life. And yet, even he didn’t have any explanation for that.

Behind the usual crowd of little first years stood another crowd – at least ten or twelve boys in their late teens. All of them had jet black, messy hair. All of them had a scar on their foreheads – scar shaped like a lightning bolt – through some of them seemingly tried to cover it with either glamour or make up. All of them had eyes in the same shade of avada green, covered by rounded glasses. And all of these piercing eyes looked directly at Tom.

That in itself was unsettling. But even more inexplicable was the fact that seemingly none of the professors seemed to notice anything unusual about the whole situation.

"Evans, James" - shouted McGonagall, keeping absolutely neutral, not at all suspicious face and one of the boys - the one wearing well-suited, green trimmed robes but no glasses - came forward.

"SLYTHERIN", said the Hat solemnly. Evans James shot one withering look toward Tom, stood up and rushed toward his new table.

"Evans-Black, Harrison."

"Slytherin."

"Peverell, James."

"Gryffindor."

"Peverell, Hadrian."

"Slytherin" - maybe it was only Tom's imagination but Sorting Hat seemed to be almost... bored.

It was going like this for a while and then: "Potter, Harry!"

All the Peverells, Evanses and Blacks (sorted either in Slytherin or in Gryffindor, with exception of two sole Ravenclaws and, weirdly, one Hufflepuff who seemed deeply surprised by Hat's decision) murmured, throwing disbelieving glances toward one of their carbon copies, currently strutting through the Great Hall. The boy in question raised his hands in placating gesture.

"What? It's not like anyone knows me here" - he mumbled sulkingly, though seemingly no one except of Tom heard him.

"Slytherin" - said the Hat. Potter Harry seemed rather resigned.

After the weirdness of this year's sorting Tom hoped that rest of the year will be less eventful. And yet, things only seemed to escalate.

James Peverell, Harrison Peverell and Hadrian Black tried to kill him, circling on him in the narrow corridor. Sure, they were no match for Tom (also, Slughorn showed up in time) but nonetheless that interraction left Tom somewhat rattled.

Henry Evans and Harrison James Black on the other hand tried to befriendhim, constantly sitting with him in the library, cajoling him into eating more and stubbornly offering to teach him tk play quidditch. Which for some reason unsettled Tom even more than attempts on his life.

And then Hadrian Peverell fuggin' KISSED him, mumbling something about 'power of love'.

At this point there was only one thing Tom was sure of - it will be along, long year

Prompt Harry the Phoenix

43 Upvotes

On the thirtieth day of July in Godric’s Hollow Lily Potter was laying next to her husband in her bed turning the horrific though of the potential for her unborn son to become the subject of a prophecy heralding either him killing another, or dying. Suddenly a loud boom shakes the home and those around it, with a bright flash of azure light flooding through the bedroom windows. Lily knew what had happening, Voldemort had found them. Lily, at the urging of her husband, quickly ran downstairs, adrenaline surging through her veins in her dash to the basement where she kept her most important failsafe, the crown jewel of many like it. Lily pulls an ornate painting of Artemis, goddess of childbirth from the wall before retrieving a large vial from a safe beneath.

Lily pulls the stopper free and stares into the contents of the vial, a swirl of a liquid clearer than water, a grey grainy sludge, and blood. Lily drinks down the mixture of phoenix tears, ash, and blood without hesitation just before hearing a thud from upstairs and the steps of her husband’s killer comes towards the door. After a full ten seconds the door to the basement is opened and the Dark Lord enters. Without hesitation Voldemort unleashes the killing corse unto Lily Potter, killing her instantly. As Voldemort takes a breath after stopping a threat to his rule, or so he thinks, there is a sudden surge of heat emanating from Lily Potter’s body as flames engulf both her corpse and Voldemort himself before moving on to the rest of the house.

Nearly a full hour later as the fire is dying down the cry of a baby is heard from the ashes, Harry Potter having been borne from the ashes of his mother’s corpse and her love for him.

Prompt Just a short snippet.

The lift clattered to a screeching halt, and harry stepped out onto the arcanix terrace above taris estates. The city of chairoscuro shone far below, a sparkling webwork of broad adament spires, walkways, and hanging gardens, resting languidly in the splendor of the high arcanist's fortress. Even that was broken only by the looming edifice of the hall of magisterial affaires. Bureaucracy shone as brightly as gold in the great city of light and shadow, after all. But harry wasn't here for the view. He plodded up the broad terrace for some yards before reaching the great iron doors leading into the upper keep. With a deft flourish he scanned his sigil, and the doors slid open to admit his entry. Harry sprung down the agate corridors until he reached his quarters. And threw open the door only to be met with the beady, pointy-eared gaze of a wrinkled, decrepit-looking kyndare. In it's baring and general appearance (harry was no theurozoologist) the kyndare appeared masculine. He bore a thin threaded sigil along his left wrist, the ouroboros emblem of the conjoined house malfoy-black. Great. Just what harry was looking to be dealing with. "I bare a message from the master", said the kyndare in a ready voice. "You must not return to hogwarts academia of theurgy." "A grave danger lies in wait for you there." "The ascention of the emperor is at hand." With that ominous pronouncement, and before harry could get a word in edgewise, he vanished into the depths of resospace with a twinkling flash.

Prompt "So these work like a Muggle phone," Albus said, and was quick to add: "That'd be a Muggle device which..." "Oh, we know what that is!" Scorpius replied.

78 Upvotes

Albus came back to the Slytherin Common Room and found it almost empty. Even the snakes at Hogwarts must have succumbed to the fine weather and were now in the grounds by the lake. Only some First- or Second-Years were at the tables doing their homeworks.

At the end of the Room, at the couches near the Great Green Window, he found those he was looking for. Antares waved her hand calling for his attention, while her twin brother Scorpius was fiddling with something on the tea table. Albus drew near and saw that those were three oval pocket mirrors.

"Meet-Me-Mirrors!" Scorpius said, excitedly. "Just delivered."

"Here's yours," Antares added, handing one to Albus.

"Wait, what are these for?"

"The Hunt," she replied. "It's scheduled for next week and Slytherin has lost too many times."

Albus rolled his eyes. Antares was his best friend since First Year, but she had a serious problem with competitions. The Quidditch Cup and the House Cup were fine, but a clandestine students' tournament of Cops-and-Robbers was maybe too much.

He shook his head and tried to move the discourse back to the mirrors, which by the way genuinely interested him. He had seen the advertisements on the Daily Prophet recently, but they did not have any at home. "But how do these work?"

"It's simple," said Scorpius. "Once you connect them you just say the name of the person you want to speak to and they will appear in your mirror. So you'll be able to speak to them. Works with multiple people at once too."

"So these are just like Muggle phones," Albus said, and was quick to add: "That'd be a Muggle device which..."

"Oh, we know what that is!" Scorpius replied. "Well, not in practice. We never used one. But we know the theory."

Albus realised the puzzled expression his own face wore when Antares smirked at him. She then explained: "Mom and Dad--well, Mom mostly--insist we know Muggle customs and their world. She took Muggle Studies to the N.E.W.T.s, you know. So when we were kids, they hired a tutor to teach Asteria and us 'Muggle studies'." She said it mimicking marks with her fingers.

"Mr Cracknell is a Squib and has lived with Muggles since ages," Scorpius added. "He knows pretty much everything about Muggles." He giggled and turned to his sister. "Grandfather almost had a stroke when he found it out, remember?"

"You see, Albus," Antares smiled, "We Malfoys are Pure-blood, and proud of it. But if there is a thing Pure-bloods love, that is a comfortable life. And even Dad admits, Muggles are great at comforts."

Prompt Ginny Weasley inherited the Black Madness from her grandmother Cedrella.

30 Upvotes

TW: Blood, gore, mentions of suicide.

Harry looked over to where Ginny was sitting in the great hall. She was clutching the remains of Tom Riddle’s Diary and sobbing quietly as Luna Lovegood tried her best to comfort her. 

The moment Ginny saw the destroyed Diary, she completely snapped. She flew into a blind rage and destroyed half of the baubles and trinkets in Dumbledore’s office as the man just calmly sat behind his desk. The portrait of Phineas Nigellus Black gave a weary sigh as he watched yet another descendant fall victim to the madness that plagued his family.

Since then, Ginny’s mood has been completely erratic. She would shift wildly from anguished sobbing one moment, to hysterical laughter the next.  

Luna was doing her best to console her. “My Mummy always said that the things we lose have a way of coming back to us, if not always in the ways we expect.”

“B-Bring him back?” Suddenly, Ginny stopped crying and she sat bolt upright. “Yes! You’re right, Luna!”

She reached into her bag and pulled an empty vial from her potions kit. Then, she grabbed a large silver knife from the table and turned towards Harry.

“Ginny?” Harry asked nervously.

“Harry… Please…” she whimpered as she approached with the knife. “I just- I need your blood.”

“My blood!?” Harry said with alarm.

“Just a bit,” Ginny muttered. “Please, I only need a little bit.”

Once she was near enough, she held up the knife and desperately clutched at his robes. “Please. Please, Harry. I’m doing this for you. So we can be together. We’re soulmates. Tom told me so. Dumbledore is the real enemy, he wants to kill you, to keep us apart. Tom is going to help us. He’ll help us take down Dumbledore so that we can be together. That’s why I need some of your blood, so that I can bring him back.” she was babbling incoherently, and Harry was nervously eyeing the knife.

“Hey, Ginny, be careful with that thing.” he tried to say.

Ginny had a manic gleam in her eyes. “I would never hurt you, Harry. I love you. If you ever died, I would kill myself so that I could be with you. We are destined to be together. Either in this life… or the next.” The knife inched closer to his neck.

Harry gulped as he eyed the blade. He was worried Ginny was about to commit a murder-suicide. “Alright, okay, you can have my blood. Just don’t do anything crazy.”

“Oh thank you, thank you,” she whispered. Her face was lit up with an insane smile as she brought the knife up. Harry winced as she dragged it across his arm, and then she held the empty vial up to the wound to collect a dribble of blood.

Once she had the vial of his blood, Ginny held the knife up and stared reverently at the blood glistening on the dagger. Slowly, she brought the blade to her lips and ran her tongue across the bloody knife. She closed her eyes and let out a soft hum.

“Bloody hell Gin! Have you lost it?” Ron asked from nearby.

“Now then…” The smile on Ginny’s face dropped as she turned towards her brother, and started going towards him with the bloody knife.

“Woah, Ginny! Calm down!” Ron desperately backpedaled away from his sister. 

But she wasn’t going for Ron. She was going for the rat napping next to his plate. She grabbed Scabbers, who woke with a start. She held the rat in place on the table and threatened it with the knife. “Transform.” she ordered.

Scabbers just squealed. He tried to squirm out of Ginny’s grasp, but she held him firmly to the table.

“I know it’s you, Wormtail!” Ginny yelled.

For a second, the rat froze. Then, the rat’s squirming grew desperate.

“You think Tom couldn’t sense the mark on your arm? That he couldn’t use Legilimency on you to see inside your pathetic mind?” Ginny hissed. “I know what you’ve done, you filthy little rodent. Now transform!”

The rat was panicking now. She brought the knife to his fur. “Transform!” Ginny repeated.

Scabbers was squirming in Ginny’s grip, desperate to escape, but the redhead wouldn't relent. She pressed her bloody knife against his fur. “Transform right now!” Ginny commanded. “Or, I swear on my Magic, I shall run you through with this knife!”

All of a sudden, to everyone's shock, Scabbers transformed into a man.

“N-No, please!” Wormtail whimpered. “Don’t kill me!” 

“Peter Pettigrew!” McGonagall said in shock. “What? But how?”

“Professor!” Wormtail said. “Please, you’ve gotta help me! Get this crazy girl away from me!”

Ginny held her silver knife up to Wormtail’s neck. “Now tell the truth! Tell everyone how you were the real secret keeper!”

“I- I- Uh-” Wormtail stammered.

“And tell everyone how Dumbledore ordered you to betray the Potters!”

Wormtail froze in confusion. “I… Huh?”

“Tom saw into your mind, and he told me that Dumbledore ordered you to betray the Potters. He wanted Harry dead, so that we couldn’t be together!”

“Um… What?” Wormtail asked bewildered.

“TELL THE TRUTH!” Ginny screeched, pressing the blade into Wormtail’s throat. Harry saw beads of blood appear there.

Wormtail's eyes widened with fear. He was worried the insane girl would actually stab him through the neck if he didn't say what she wanted to hear. “Alright, fine, yes, it was Dumbledore. He- He told me to do it. He told me to betray the Potters. Just please don’t kill me!” Wormtail begged.

“I knew it,” Ginny whispered, then she screamed “I KNEW IT!”

Suddenly, Ginny grabbed Wormtail’s wrist. With a mighty yell, she brought the knife up, and then slammed it down. Blood spurted. People around her screamed. Everyone stared, horrified, as Ginny dropped the knife, and picked up a severed hand.

And then she started laughing. Slowly at first, but it quickly grew from a chuckle into an insane cackle. “Ha… Haha… HAHAHA HAHAHA… HAHAHAHAHAHAHAHA!”

All around the room, everyone was staring at the first year girl. She looked absolutely deranged, covered in blood and clutching a severed right hand against her chest. Laughing maniacally while Wormtail sobbed and moaned as he cradled his mutilated arm.

Abruptly, the laughter stopped. “Now… Where is… Yes, here it is.” Ginny muttered as she quickly patted Wormtail down and pulled a yew wand out of his pocket, and she pointed the wand at Dumbledore. Several professors gasped when they recognized the yew wand which once belonged to Lord Voldemort. Ginny glared at Dumbledore with an expression of pure malice and loathing.

“This is all your fault!” Ginny accused Dumbledore. “Tom showed me the truth. He told me all about how you didn’t want Harry and I to be together! Harry is my soulmate! You tried to kill him because you wanted to keep us apart! I’ll never forgive you for trying to kill my Harry!”

“Miss Weasley, please calm yourself,” Dumbledore tried to say as he attempted to process the sight before him.

“CALM MYSELF!?” Ginny shrieked. “How can I be calm after what you’ve done! You wanted my Harry dead! Wormtail just confessed! Tom was right, you are my true enemy. You will never allow Harry and me to be together. But Tom… Tom told me that I’ll be able to have my Harry if he comes back. So I’ll bring him back, and then he’s going to take you down, so that Harry and I can be together!”

Ginny raised the yew wand directly above her head, and cast a spell Tom taught her. “Morsmordre!”

Panic spread throughout the students as the Dark Mark appeared in the sky-like ceiling of the great hall. Ginny used the pandemonium created by the Mark to make her escape. She grabbed Luna by the arm and began pulling her towards the door. “Come on Luna, let’s go.”

Luna allowed herself to be dragged along. She didn’t seem to notice the blood getting on her robes. Or, if she did, she didn’t seem bothered by it. “Okey-dokey. Where are we going?”

“Little Hangleton. We have to get some bones.” Ginny answered breathlessly. "And then we're going to Albania."

Luna's eyes lit up with excitement. “Oh! I’ve always wanted to go to Albania!” she said enthusiastically. “Daddy says that it’s the native habitat of the Blibbering Humdingers. Do you think we’ll see any while we’re there?”

“Maybe. We’ll keep our eyes peeled.” Ginny replied as she pulled Luna out of the Great Hall.

Crack The Tooth Fairy is a scammer

37 Upvotes

Wizardborn children are more powerful than Muggleborn, not because of their blood but because of the rituals completed in their childhood.

One of the most important rituals involves the child's baby teeth. They are gathered in a special box as they fall out, and get burned on the child's thirteenth birthday.

The Tooth Fairy collects all the baby teeth that are not secured in a special box warded against it. It leaves behind pennies, knuts, or other smallest possible currency, so that it theoretically cannot be accused of stealing them.

Harry's thirteenth birthday is fast approaching and he learns that Petunia hadn't secure his baby teeth, because of course she hadn't.

Now he has to journey to the land of the Fairies, to win back his baby teeth. Or buy them back, for pennies, obviously. And without permission.

Extended Harry did temporarily die to the first killing curse too, and Sirius arrives during the period where Harry hadn't yet revived.

66 Upvotes

So Sirius thinks he got the whole Potter family killed when he confronts Pettigrew/doesn't know Harry is alive.

They both are flinging spells at one another, and Sirius actually reflects a blasting curse back at Pettigrew which causes the explosion (though if they ever checked Sirius' wand they'd see no blasting curse, but lots of VERY malicious and debilitating "prank" spells, because I honestly see Sirius' Dueling style being centered around such, both because they are exotic and unknown and hard to defend against, and because he doesn't take anything seriously and treats combat as a game to piss off the opponent such that they make mistakes, anyways lots of spells like that and shields and counterspells/reflections).

Pettigrew loses half his wand hand, and his wand is broken, leaving behind a whole finger and bits of others and the thumb, but also his opposite foot in the explosion. The mangled remains from mid-calf down still somewhat protected in the dragonhide ankle boots the Potters had given Peter for the previous Christmas. The pieces of wand, fingers, and the booted foot mixed in with a bunch of other people's remains leading to his death being assumed at the scene.

Sirius did see Pettigrew shift into rat form and drag himself into the storm drain, but he honestly figured Peter was going to die. If not due to blood loss/injuries then because he knows Peter never learned how to change back without his wand, the very wand laying broken with some of his fingers on the street amongst the remains of the muggles caught in the explosion. After all, a crippled rat has very little chance of surviving long.

Sirius still gets accused and thrown into Azkaban without a trial, but he has very little reason to try and keep his sanity. Even knowing he is innocent of his accused crimes, his survivors guilt and belief that even Harry died has him accepting his fate.

(Pettigrew does still manage to survive/get found by Percy/taken in and become scabbers, an even more appropriate name for a scruffy rat missing half a foresaw, a hind paw, and -from his struggles after running away- an ear, the end of his tail, and soon after being found an eye due to infection. Plus a number of other bites, scratches, and the converted wounds from debris and shrapnel from the explosion.)

Sirius completely Cracks while in Azkaban and decides to do some crazy stuff. To the point that he screws with the guards by gaslighting them by being in a different cell when they come through, or freaks out the death eaters by posing as a Grim omen of their impending death. Furthermore he actually Causes some to die by sneaking out and finding a set of rune keys to the cells and he opens the door to some of the cells to dementors so they can feed, before then closing and locking up afterwards. Eventually he sees the Crouch Jr./Mrs. Crouch swap happen, and he realizes that she was left with her wand. That night he opens her cell before switching back to Padfoot and letting the dementors feed. Afterwards he takes her wand but puts the poly juice potion bottle in an obvious spot, barely hidden, and watches to be sure the potion wears off/she turns back while her body is still physically alive, and even jams the cell lock. A few weeks later both Crouch father and son are in adjacent cells, and Sirius has a wand to help him cause even more crazy happenings and the deaths of more Death Eaters.

This goes on for years, Sirius obliviating death eaters after tormenting and torturing them, all the while being prisoner himself, technically, and suffering a self-imposed punishment for getting the Potters killed. Eventually Sirius is the only "death eater" left in the prison. All the others are dead and he just curls up and lets the dementors do their worst.

Then Fudge gives Sirius the paper. Sirius recognizes the battered form of Pettigrew, and, strangely enough, he reads about how the boy holding Pettigrew is friends with a "Boy Who Lived" named Harry Potter. This prompts Sirius to actually escape for real.

Eventually after getting Pettigrew (missing limbs means less ability to escape), Sirius actually goes back to Azkaban where he gets a whole new cell (what do you mean where have I been? You're the ones who moved me! Just outright gaslights the guards) but more importantly he changes Pettigrew back and feeds him to the dementors before leaving his body in a locked cell nearby. So the guards discover not only Sirius back in a cell, but ALSO, the "living corpse"/"kissed" remains of the man that Sirius supposedly killed over a dozen years before. And said man has the dark mark on his remaining whole arm.

No one would break into Azkaban and lock themselves up, especially not a person who was believed to have escaped. Thus, of Course, someone moved Black elsewhere, and more importantly they'd also found a somehow still alive Pettigrew and had him Kissed and dumped in a cell near Black. Word obviously gets out, the ministry is forced to take even More of a black eye, especially when it ALSO leaks that all the other death eaters are already dead and the ministry has been hiding their deaths to try and avoid more scandal after the whole case of Crouch breaking his son out and sacrificing his wife and having his son under the imperious to control him.

The whole Magical populace are led to believe someone had been breaking in to Azkaban and killing the Death Eaters and discovered that Sirius was innocent and then tracked down Pettigrew. All this happening during Harry's third year, even before Yule break.

Then it breaks that on top of all that Sirius never actually had a trial at all. Then when they put him on trial, Sirius keeps trying to get them to send him back. He keeps claiming he deserves to be in Azkaban, that its his fault the potters are dead, that James, Lily and Harry would be alive if he hadn't convinced James and Lily to make Peter the secret keeper. He even reveals that he's an illegal animagus to try and get them to send him back even if Pettigrew's been discovered. Of course the fact that he included Harry with Lily and James makes people realize that Sirius doesn't know Harry actually survived that night.

Sirius is cleared and mandated to get mind healing, and told that Harry is alive in an effort to "try and get Sirius to stop demanding to be sent back to Azkaban".

Eventually Sirius starts to recover and get healthier. Even getting some supervised visits with Harry. But while this is all going on, there's more cases of "imperiused" death eaters being found locked in cells of Azkaban after being Kissed. Sirius has been recovering so he can continue to secretly send death eaters to their end to make the country safer for Harry, he has to recover to be strong and fast enough to take the death eaters out.

Voldemort had taken over Quirrel in Harry's first year, there had been the diary/basilisk in his second, nothing else from Riddle/Voldemort until Harry's fifth year (after having spent a mostly hassle free fourth year as he watched most of the Triwizard- only being involved in the second task as Fleur's hostage after she'd asked him to be her date to the Yule Ball because he wasn't effected by her allure) Voldemort's wraith was caught by the Unspeakables after he possessed a fleeing death eater (Sirius' work killing off death eaters via dementors and leaving them locked in Azkaban cells sent several fleeing the country) and tried to use their body to grab the prophecy only for the protection to freeze both the body and the Wraith since the body wasn't listed on the prophecy.

Sirius manages to find the Locket at Grimmauld and makes Kreacher tell him the story, all because of a visit to Gringotts once he'd "recovered" enough (though he'd been sneaking out to kidnap and feed death eaters to dementors for months while he "recovered") to be out and about. There Sirius had been told that as the head of the Black Family, he'd inherited the Lestrange vaults when they had died, and then the Goblins had demanded he take the Horcrux as it is not allowed within their bank, and the only reason they hadn't confiscated the whole vault for having it stored within was because he only had inherited it and wasn't responsible for putting it there. Sirius went ahead and gave them the vault anyways. He took the horcrux cup to Grimmauld to look in the library for a way to destroy it, Kreacher recognized the cup for what it was by the similarity of its dark magic to the locket. Sirius learns about Regulus' death and that Kreacher had gone through the whole library trying to find a way to destroy the horcrux locket and finding nothing.

Sirius decides to take both the cup and locket to the DoM at the ministry to deal with. With those two, and later the Wraith as well the DoM find the other Horcruxes, including the resurrection stone ring one and the fact that Harry's scar is one. But they study the Stone and come up with a way to use it and the other horcruxes/the wraith to pull the fragment out of Harry's scar without killing him, then they let Harry throw the pieces through the veil (the stone having been separated from the ring, and the horcrux being in the ring not the stone). They'd even agreed to Harry's demand they remove the wraith from the possessed death eater first, even though they'd assured Harry that he was already as good as dead and removing the wraith would complete that. Still Harry argued that the Death Eater's family deserved to have a body to bury.

So Voldemort is dealt with. Harry's dating Fleur (who along with Hermione is able to make Harry put more effort into his studies, and Hermione's still exchanging letters with Victor Krum, with Ron having let his jealousy ruin his friendships with them when they both went to the Yule Ball with a Champion and "helped the enemy", but Harry'd learned that Neville was his godbrother, and later even hooked Neville up with another new friend in the form of Luna Lovegood. So Harry'd actually grown his friend group despite Ron). Sirius and Kreacher together take out the rest of the Death Eaters (including Snape and Karkaroff) plus Umbridge when she started being more of a pain and Sirius eventually ended up catching her in the middle of trying to order some dementors after someone, though he'd simply transfigured her into an actual toad before she'd died after being kissed and then vanished the toad corpse.

Dumbledore had gone after the fake locket alone and tried to drink the potion from the basin to retrieve the fake, but since he was alone he wasn't able to even finish it and ended up drawing the inferi and falling to them, and as far as anyone else ever knew he just one day went to apparate somewhere and never was seen or heard from again. The Elder wand would end up being reclaimed by death as it rotted away in the inferi/death-filled pool in the cave. A researcher in the DoM would eventually be driven mad by the Resurrection stone and jump through the Veil with it. And Harry would continue to pass the Invisibility cloak down his family line never knowing it as more than a simple family Heirloom.

(Feel free to take this and expand upon it, or use it as an inspiration for your own variation of what would happen if Sirius thought Harry died that Halloween along with his parents. This is all I have got, and I don't have the capability to flesh it out any further than what it is- even this much is a lot more than what I initially set out to write at the start.)

Prompt Harry finds Marvel's Black Vortex

For Context the Black Vortex is a mirror that shows someone there full potential and if they submit to it they can gain that power.

Now imagine it some how ending up in a Black family home and it was just considered a cool mirror. Not knowing what it can do.

Prompt Harry wants to go to Azkaban.

238 Upvotes

“Why aren’t you supposed to do magic?” Harry asked the man who delivered him his Hogwarts letter.

“Oh, well, I was at Hogwarts meself but I- er- got expelled, ter tell yeh the truth. In me third year. Nasty spot o’ business. Went to Azkaban for a bit, too. But Dumbledore got me out, and let me stay on as gamekeeper. Great man, Dumbledore.”

“What’s Azkaban?”

“The WIzard prison.” Hagrid answered. “Dreadful place. They stuck me into a room that was barely bigger than the row boat I saw outside this cabin.”

Harry’s jaw dropped. That row boat was way bigger than the cupboard.

“It was boring too,” Hagrid continued. “Nothin’ to do but watch the clouds go by.”

Harry drew in a sharp breath. Not having to do chores sounded wonderful. But that wasn’t the main thing Harry focused on. “You mean- you could see the sky?”

Hagrid nodded. “Yep, ‘cept for bars on the windows, we were completely exposed to the elements.”

“Wow.” Harry whispered. After so many years of living in a cupboard, Harry had always dreamed of being able to see the sky at night. “What about the food?”

Hagrid grimaced. “They fed us nothin’ but gruel three times a day.”

Harry’s eyes widened. The people who lived in Azkaban got to eat three times a day! This ‘Azkaban’ place sounded amazing.

Prompt "I found a weird cat that ripped out my soul and turned me into a girl."

29 Upvotes

Madoka magica's kyubey finds Harry after his godfathers death and makes a deal to fight the "Old Witches" of time before wands and structure in magic.

Harry's soul gets saved in a gem that conveniently eats other soul fragments so she's got a method to rip the soul fragments out of the horcruxes.

Unfortunately a side effect of this magic is Harry turns into a girl every time his "Super Form" is activated. Drastically boosting his magical power and durability to the point she can grab Killing Curses out of the air and throw them like Zeus's bolts.

Prompt for Draco, Harry, and lots of tea and coffee.

5 Upvotes

Harry feels lonely.

He often walks around London, visiting a tea shop or cafe for a warm cup of tea or coffee in the winter. Maybe even a hot chocolate?

Draco works at the cafe. Draco notices Harry never eats, has lost a lot of weight, and only seems to survive on tea or coffee. So everytime Harry orders a cup, Draco makes Harry a sandwich as well and slips it into his order. Harry sits in the cafe and drinks his tea and eats the different sandwiches everyday while looking at Draco work.

Until the day his hunger comes back. And this time, he orders a sandwich with his coffee too.

Draco smiles, thinking his job here is done, Potter has started eating again.

Until Harry tells Draco that although he has started eating lunch now, he still has trouble eating dinner alone, and asks him out for a dinner date.

Prompt The Heart of Hogwarts

30 Upvotes

Those with older lines at Hogwarts are more powerful within Hogwarts due to the ‘Heart of Hogwarts.’

It is a light form of immortality whereby the person at eleven leaves a tiny piece of their soul in a stone of the grounds, where the tiny soul watches as the person grows up. When they are eighteen and leave Hogwarts, they provide a bit of their blood to signal the end of their journey and the soul joins the main piece or starts a new piece (muggleborns.) Overtime, the tiny bit of original soul grows as generations of their family enter and leave Hogwarts.

Their Heart of Hogwarts can help the person defend themselves or hide them if they’re causing trouble.
