So I always loved to read Animagus fic, at least ones that were well written, and thought seeing as I am stuck on my other fic's at the moment I would wright this to pass the time. I also decided to use one of my favourite paring for Harry Potter (i.e. Flure).

He will only have one Animagus form, at least that is the plan for now. I don't see it changing any time soon. I do would like ideas for his 'Marauder's' name, though in this it will be more like his Animagus name. Either I will make a poll or pick one if I like it. You will see his form by the end of this chapter, so you should be able to come up with idea's :)

A warning, I may make up spells, mostly because I don't speak Latin. English is my first (and only) language and I struggle with that.

Also, while I will try and keep most of the facts about Harry's Animagus form try, it is likely that I will make some of it up. This is FanFiction after all, and I really don't see the point of spending a lot of time looking through contradictory information in book and the internet for something I am not even making money off of.

Please don't take that the wrong way, but I really do only write these fics as a hobby. I enjoy writing and seeing what people think, but I do still have a life outside these fics that I need to live.

This is starting in the summer after 'Prisoner of Azkaban'.

Don't like don't read. XP

Hope you enjoy :)

Summary: Before flying away on Buckbeak, Sirius gave Harry the notes on the Animagus Transformation that the Marauders kept hidden in the Shrieking Shack. Harry starts his preparations the moment he returns to the Dursley's. Unfortunately, no one ever told Sirius or Harry that the method the Marauders used had risks. Rate M because of language and I am paranoid.

Chapter 1- The Easy Way

XXX

Harry didn't have to wait long after returning to the Dursley's for them to leave him alone in the house, in fact it was less than two minutes after they returned from King's Cross. Apparently hearing that he not only had a Wizard Godfather, but that said man was also a convicted mass murder made his relatives uncomfortable.

They had pulled onto the drive, unpacked is suitcase, then drove off again. Harry didn't even ask where they were going or when they would be back.

Not wasting a second he pulled out the notes Sirius had given him before leaving on the Animagus Transformation that he had been reading for the past few weeks since being given them, along with his potion ingredients. He had ordered everything he would need while still at Hogwarts, though making sure Hermione didn't notice had not been easy.

Hermione was one of his best friends and he loved her like a sister, but she had a bad habit of thinking she knew what was best for everyone. She also tended to enforce her opinion regardless of what anyone else said. Ron was his best friend, but had too big a mouth at times. Harry didn't trust the redhead not to blurt something out while arguing with Hermione.

He would tell them when he went to the Burrow at the end of summer.

Taking out his cauldron Harry carefully placed it on top of the cooker so it was covering all four burners, before turning and placing the ingredients he needed on the side and started preparing them. Despite what Snape said, Harry was actually very good with potions. It was almost like cooking, only with very odd and often disgusting ingredients.

Cooking was one of the few things Harry actually enjoyed about his time at the Dursley's. He always found it relaxing, and it was the only thing his relatives couldn't say he was terrible at.

He liked to have everything ready before starting, so he could put all his focus on the cauldron while it was cooking. So as he was waiting for it to heat up he got to work, trying not to think about the things he was cutting and crushing.

The potion he was trying to make was surprisingly simple and easy to brew, though Sirius had warned him it tasted worse than the Polyjuice Potion. Apparently when his father and the other Marauders had first taken it they had lost the ability to taste anything for a week, though the effects did decrease over time.

While not the most promising idea it was the easiest, and fastest, way to discover your Animagus form.

From what he had read in the notes there were three ways to become an Animagus.

The first and hardest way was to become a master of Transfiguration, followed by months if not years of mediation. This was the most known method, and the reason so few Wizards or Witches ever even attempted it. Over all it took on average five years to become an Animagus this way.

The second was the rarest of the three and was almost unheard of. It was also supposed to be the most dangerous as it almost always resulted in the Witch or Wizard being unable to change back without help. This was when it was done with Accidental Magic, as in when a young child's magic reacts before they even started learning magic. The problem with this was that they almost never knew how to turn back, and in some case lost the ability to become human again forever.

The last was the method Harry was planning on using.

Basically the Potion he was brewing would force him, very painfully based on the notes, into his Animagus form. It would only last five minutes before forcing him back into human form, a failsafe of sorts to ensure he didn't get stuck, with the time limit getting a little longer each time he used it. After that it was a matter of remembering how it felt to transform. The idea was to keep taking it until you could remember how it felt and do it without the potion, though the notes also warned to only take it once a day.

Grimacing as he added in a size three goblet of Grindylow blood pre-mixed with Troll saliva, Harry took a step back as a small puff of dark purple smoke erupted from the cauldron. He quickly waved it away while gagging as the smell of rotten eggs hit him, trying to clean his steamed up glasses with his shirt.

It crossed his mind that he should open a window, but Harry quickly decided against it. Let the Dursley's choke on it when they got back, whenever that may be.

Overall it took Harry five hours to complete the Potion. Three to make it, one to let it simmer and then another hour to let it cool. By the end he had enough to fill thirty two vials, each worth one short of the potion. He then packed them all into a special case he had ordered along with the ingredients, before closing it.

Again from what he had read from the notes it took his dad three weeks before he stopped needing the potion, Sirius two months and Peter took almost three months. Without a doubt he would need to make more, especially if his plan to bribe Ron and Hermione into forgiving him for doing this without them was going to work. He would admit the thought that he would be able to help Hermione for once played a small part in his decision, but it really was only a small part.

Making sure to clean everything after he had finished, Harry took all of his things up to his room. He opening the window so that Hedwig would be able to get in when she arrived, his ever faithful owl having opted to fly back from Hogwarts instead of staying in her cage.

He then went to the bathroom and took the mirror hanging on the wall over the sink down and carried it into his room, leaning it on the floor against his bed before locking the door in case his relatives returned sooner than he was expecting.

Harry quickly took out one of the potions before hiding the case under the lose floorboard in his room, along with a few other things from his trunk so the Dursley's wouldn't find them.

Now sat on the floor in front of the mirror with the vial in hand, Harry took a moment to calm himself and take a closer look at the potion he was about to drink. The vial held a single mouthful of a dark red liquid that seemed to be bubbling. It was slightly see-through, and when he uncorked the top Harry was hit with a sickly sweet smell that made his mouth dry. Taking off his glasses as a last minute thought, Harry took one more deep breath before pinching his nose and gulping the entire potion in one go.

The moment the liquid hit his tongue Harry was hit with a burning sensation, almost as if he was drinking liquid fire. He was forced to suppress the reflex to gag and spit it out, eyes clenched tightly shut as he forced himself to swallow it all. The burning sensation carried on down his throat, making him grab his neck in pain and drop the vile in his hand where it rolled under his bed and out of sight. After getting passed his throat the burning collected in his stomach, and for a moment Harry feared that he had made a mistake and that the potion was going to burn a hole right through him.

Once all of the potion reached his stomach there was a moment where it simple sat there, burning him from the inside out as Harry clenched his teeth to muffle the screams. Then it started to spread out to the rest of his body. He could feel it as the burning travelled up his arms, adding an odd itching to the mixed as it moved to his hands.

While twisting on the floor Harry was somehow able to pull off his jacket, only for his eyes to widen at what he saw with his blurry vision. Following the burning up his arms dark brown, almost black feathers had started to spring up from under his skin. Turning back to the mirror as he felt the burning reach his face, Harry watched as more feathers grew over his face and neck. Though he ideally noted that the ones on his neck were a lighter shade of brown before the pain got too much to think about it. Then the sound of snapping hit his ears followed not a moment later by even more pain as he felt the bones in his legs seeming to break and reform slightly different, only to break and reform again.

He was somehow able to grab his bed sheet at this point and bite down on it to further muffle his screams, only for him to suddenly realise he no longer had teeth or even lips. Forcing himself to look in the mirror again, Harry saw that instead of a mouth he now had a hooked yellow beak with a black tip.

It was then I realised that his vision was no longer blurry, and a glance at his eyes showed that instead of their usual green they were now a bright gold with a black diamond pupil. That was the last thing Harry was able to think about before the burning got too much for him to concentrate on anything else. For the next few minutes Harry could do nothing but thrash around and try not to scream as it felt like his body was being turn burned and torn apart at the same time over and over again.

Then without warning, just as he thought he could take no more and was going to pass out, everything stopped. The burning, the breaking, everything was simple gone as if it was never there at all. Even the memory of the pain was becoming duller for some reason.

Blinking rapidly as he opened his eyes to see his now much shorter height, Harry tried to stand up only to fall flat. He tried to use his hands to catch himself, only to find that he didn't have any hands. Instead there was a pair dark brown, almost black wings, with lighter brown feathers where they connected to his body.

Getting excited Harry gave up on trying to stand and instead rolled himself into a potion so that he could see the mirror, although even that was harder than it should be.

The bird looking back at him in the mirror was beautiful, if a little odd because of it lying on its side in such a strange position. Its head, chest and wings were all covered in the same dark feathers. While its shoulders and stomach had lighter feathers. The very tips of his wings were white, along with a strip of white over his tail. That had been a little odd when he turned to look at it, suddenly having a tail. Then there were his feet, which were now yellow bird feet with inch long black talons.

The only odd thing was a familiar shaped crack on the right side of his beak, though it looked like it had healed a long time ago. He should have known that his Animagus form would have some reminder of his scar, though why it was on his beak he didn't know.

After he was done examining himself, Harry rolled onto his stomach and attempted to stand again. It took several attempts, and he was sure he had scratched the floor with his new talons at some point but after much struggling he was able to get up. He didn't dare try and take a step, not trusting himself yet in this new and completely different form. It was hard enough to simple stand with his talons getting in the way.

Harry was able to quickly notice that he felt a lot lighter now, though simple wrote it off as a bird thing. He would have to try and find out what specific species of bird he was…

But before Harry could think about it anymore, he was once again hit with the same burning pain that the potion gave him. It didn't last nearly as long though, and within two minutes Harry was back to his normal body.

He was crouched on the floor using his hands to keep his balance, panting heavily as sweat dripped off his skin and hit the floor. After getting his breath back, Harry blindly felt around for his glasses. But despite everything, the pain, and sudden exhaustion that hit him…

Harry couldn't stop the grin crossing his face as he looked in the mirror.

"…I…did it…"

The next day Harry saw his relatives for only a few minutes while they packed, having returned in the middle of the night. They were apparently taking a trip to visit Aunt Marge, fir the rest of the summer. This meant that he would not be seeing them for the rest of the holiday, a fact that neither he nor they were bothered by.

Harry was a little surprised when they let him enough food to last him through the summer, if only barley. But then again the new threat of an insane magical godfather coming after them seemed to have…given them a reason to be nicer to him. They even gave him a spare key to the house.

They had left before breakfast, much to Dudley's horror.

It was about a week later that Harry caught a bus to the local Library. He had been taking the potion every day and the pain was almost ignorable now, though still enough to make it hard to focus on the actual feeling of the change. He was able to move around in his Animagus form now, though Harry hadn't dared try and actually fly yet. His time limit had stretched to about fifteen minutes, but considering how long it took him to simple walk Harry wasn't confident.

He was a little worried that Hedwig hadn't arrived yet, but assumed she was simple enjoying her trip back without need to worry about delivering his mail.

The ride wasn't too bad, even though the bus was packed. The Dursley's had made sure that everyone within a mile radius of Private Drive knew he was a 'insane', so no one that recognised him came near. Even with the red cap on his head hiding his hair, most people recognised him.

When he did reach the Library Harry quickly made his way over to the public computers, and after waiting for his to load started looking for information on his Animagus form. It took longer than he would have thought, though the fact there were so many different types of birds around the world and he didn't even know the name of the one he was looking for slowed him down.

But after three hours of endless pictures of birds, Harry finally found the one he was looking for.

Basic description taken from Wiki

XXX

The Harris's hawk, formerly known as the bay-winged hawk or dusky hawk, is a medium-large bird of prey that breeds from the southwestern United States south to Chile and central Argentina. Birds are sometimes reported at large in Western Europe, especially Britain, but it is a popular species in falconry and these records almost certainly all refer to escapes from captivity.

The Harris' hawk is notable for its behaviour of hunting cooperatively in packs consisting of tolerant groups, while other raptors often hunt alone. It is the Harris's hawk's intelligence which leads to a social nature which results in easier training and has led to the Harris' hawk to become a popular bird for use in falconry.

Harris' hawks live in sparse woodland and semi-desert, as well as marshes (with some trees) in some parts of their range, including mangrove swamps, as in parts of their South American range. Harris' hawks are permanent residents and do not migrate. Important perches and nest supports are provided by scattered larger trees or other features (e.g., power poles, woodland edges, standing dead trees, live trees, and boulders and saguaros.

There were several pictures of Harris Hawks with slightly different shades, some with more white then his Animagus form, but there was no doubt that he found the right one. After paying the librarian, an old man that looked like he might give Dumbledore a run for his money, to print off the information so he could look at it again later Harry moved to leave the Library.

He was just coming up to the door when he saw a familiar and very unwelcome face, along with several other he wasn't familiar with.

Piers Polkiss was his cousin's best friend, and one of the many people that made his life hell before he started Hogwarts. He still looked like a rat to Harry, though after meeting Wormtail the image wasn't as strong as it had been the last time they had met. He was also still smaller and skinnier then Harry, which was only further enforced by the two gorillas' walking on either side of him that reminded him strongly of Crab and Goyle.

Seeing that they hadn't noticed him yet Harry quickly lowered his head so that his hat hid most of his face from view, hoping to get pass them without them realising he was ever there.

Unfortunately, that hope was shattered when Piers being his usual arse moved so that Harry walked into him.

"Hey why don't you watch where you're going, you better say sorry for bumping into me!"

Harry could hear the smugness in the teen's voice as the two others moved to either side of him, boxing him in and smirking at his smaller form. He actually considered just saying sorry and walking away, but before he could Piers decided to punch him in the stomach.

Now while the rat faced teen wasn't that strong, the fact Harry wasn't expecting the punch meant it winded him. He fell to his knees holding his stomach, glasses slipping off his face and hitting the ground between him and Piers' feet. All three of the teens were laughing now, and before Harry could make a move to take his glasses back Piers step on them, crushing the frames and shattering the glass.

It was then that something…odd happened.

Harry felt a burst of red hot anger well up inside of him, only to realise that it wasn't just anger when he felt it moving to his eyes. His blurry vision cleared as his fists turned white and a snarl grew across his lips and tilted his head slightly to look up at Polkiss, one eye now visible under the hat. What Harry didn't know but would figure out later was that the eye now glaring at the laughing teen was no longer its usual emerald green, but the glowing gold of his Animagus form.

The moment Piers stopped laughing enough to look down and see this, his face paled and he backed away in fear. He quickly took another back when Harry stood back up, still unable to see his face because of the hat covering most of it.

The two teens on either side of Harry didn't see his eyes however, or understand why Piers had started backing away and look like he had seen a ghost. If they had, they may have been able to avoid what happened next. Using the speed he had honed as his time as a Seeker, Harry turned to the one on his left and hooked his leg behind the boy's left knee. This brought his face down close enough for Harry to slam his fist into the guy's nose, which exploded with a spurt of blood.

Turning away from his first victim for the moment as he tried to stop the bleeding, Harry was able to catch the other teen that had been on his right in the stomach as he attempted to charge him from behind. The guy also fell to his knees, winded and clutching his stomach. Not giving him time to recover Harry aimed a punch at his left temple, knocking him out instantly before turning and repeating the punch to the other.

With his shirt now slightly stained with blood and his chest heaving Harry slowly turned to Piers only to see him legging it down the street, just before he turned a corner and was out of sight.

Harry returned to Private Drive in a daze, his body moving on auto-pilot. The adrenalin had long since left his system, leaving him drained and confused. He had no idea where the anger or the strength for that matter, had come from. It had felt like nothing he had ever felt before, almost like the first time he had flown on a broom.

He moved to the stairs to the bathroom, splashing water in his face and trying to shake the cobweb from his head. His muddled mind ideally noticed that he was still able to see despite not having his glasses, and he glanced at his reflection to see his usual green eyes looking back at him. However as he was looking, Harry saw a brief flash of gold overtake them for a moment before returning to normal. If he hadn't been looking he would have missed it, but for less than a second his eyes had changed to his Animagus forms.

Harry tilted his head to the side slightly, idly noting that it was a very… bird like motion.

Part of his mind was screaming at Harry that something wasn't right, that he needed to send a letter so Hermione or maybe even St. Mungo's and ask for help. But another and apparently louder part of his mind argued that this was a good thing.

His eyes were fixed, in fact they were probably better than most normal people's eyes at this point. Sure he had beat up those other boys in a fit of rage, but they deserved it. They had started it, not him. Harry had simple reacted to the situation.

Fight or Flight.

They had cut of his option of Flight, so Harry had been forced to Fight.

The more he fought about it, the quieter the other voice got until it was little more than a whisper in the back of his head. There was nothing wrong with him, Harry had done nothing wrong. With these thoughts, Harry turned away from the mirror and made his way to his room, taking another Animagus Potion from the box and necking it without a second thought.

Hope you liked it :)

As you can see, Harry us starting to get the negative effects from the method he is using to because an Animagus. That being he is starting to struggle to keep his 'inner animal' separate from his human side.

Looking at both Sirius and Wormtail, I thought it seemed like a logical move. Peter is more rat then man when he is found in the third book, and Sirius is more or less a dog in many ways (if you get my meaning ;)

The reason for this will be explained later in the fic, I already have a plan for why it is happening. Having said that, I am not sure if I will have Harry, Ron and Hermione realise what that is until after Ron and Hermione start to take the potion themselves. Not sure what I would have them become yet though.

Don't get me wrong, they will notice something is different about Harry. But they are still only kids at this point and the idea of being about to become Animagus might just be a little too tempting and through off even Hermione's common sense.

Let me know what you think. Next chapter should be longer.
