Review answer corner:

One Punch Saitama + Vladimir Mithrander: Don't worry Harry has no MPD nor is he suddenly a genius, I wrote it this way to showcase how Serpentarius/Harry is able to maintain his self as a normal brain of a 1 year old - magical or not - is incapable of so much focus and memory capacity, it's why we do not remember our earlier years. For him to retain his adult mind and memories at least partially he needs more than just innate magic. Nor was the process easy. I wanted to show that. No super brain, no split personalities.

VeltaIO: Oh you flatterer. Are you trying to get in my pants because I gotta tell you it worked. Reading your review had me honest to god squealing. Embarrassing I know lol but I couldn't help it! I put a lot of thought behind the future arc, it was never supposed to be that long - I don't blame you for skimming I'd probably done the same as eager as I am for the juicy bits -_-" - but I couldn't just cut anything out as you are right and we will see the agents of the tower again. Harry spent decades building up his Organisation do you really think he was going to just leave them behind? He knows exactly what the future looks like so he's thinking big. It will be a little while though before he releases them to unleash their brand of chaos no matter how eager they are.

As for active changes in cannon; Harry will try his best but he's a toddler, so his interference will be small at the start but will snowball as he grows. No one said Harry couldn't be a manipulative little shit too. lol

Though I can say I'm altering cannon a bit with background info and manipulations that could fit into cannon because it was never shown or mentioned. One detail I changed for sure is Dorea and Charlus Potter being James' parents I now know it was actually Fleaumont Potter but by the time that it was revealed I'd read so much fanfiction that Dorea being Harry's grandmother had already become an unshakable fact in my mind. I kinda like James being half Black, what with his overwhelming talent in transfiguration, it makes sense. And the Black Family is just plain awesome.

As for the identity of 'Lord Grandfather' and Mystery Sleeper you'll all have to wait and see, but I'm always curious what you guys come up with.

Of Names and Birthdays

31st July 1981

Potter Manor, Wales

.

Hair done up carefully and dressed in freshly pressed robes in gold and green, Lily stood in her sons nursery and was just finishing dressing her son in the cute lion onesie Remus had brought over last time, she had been saving it for the best occasion and today was too good to pass it up. With his dark hair so wild and messy and showing all symptoms of the infamous Potter hair, already so much like his daddy's, Harry's hair truly resembled a mane and so fit perfectly, the soft curved ears affixed to the hood and bushy tail were almost too much and gave her camera a real work-out. James was going to love this. Looking at the mini-James, she idly wondered if James ever wore such cute onesies, Dorea hadn't seemed the type but still... she'd have to ask the house elves the potential blackmail opportunity was too good to pass up.

Grinning at her son, Lily lifted him into her arms feeling more awake and better yet; like an actual human being again, after that long hot shower, she even looked it upon a closer look, even if she had to resort to subtle glamours to cover up her eye-bags.

She has had a quick brunch, Harry had his fill of milk, had a fresh nappy, the decorations were mostly done and the houselves had ventured out into the manor again and had resumed their duties and were cranking out one party snack after the other... all was about set for the guests to arrive.

Now if she only knew where her husband had gotten off to...

She could ask the house elves but she was loath to actually call them so late at night or rather so early in the morning and as opposed to usual she had yet to spot a single one in the halls, usually she always saw at least one happily polishing away in some corner. So peculiar.

Since there were no alternatives forthcoming and the paintings of her in-laws were being particularly unhelpful she withdrew her wand and cast a locating charm jumping when it led straight back into the room she just came from. The nursery.

Narrowing her eyes she strode back in her son still positioned on her hip. Like she thought flimsy white curtains chest filled with plushies and toys a dresser the crib and baby changing unit... no husband to be seen, but her spell wasn't wrong. Her eyes narrowed on the closed closet doors... he better not have taken up vigil in there - she should never have told him about the muggle children superstitions about monsters in the closet, he had already gone overboard with the anti-boggart spells.

Wrenching the door open she was relived to find no husband staring back at her, but the sudden noise resulted in a startled faint snore. Looking down at the curious emerald eyes of her son, who was looking around now for his Daddy too, Lily narrowed her eyes. Listening closely, she turned to the corner of the room to the deep blue arm chair with its cyan cushions, staring at the dubious depression on it's surface suspiciously. Setting her son down into the crib she grabbed her camera off the dresser (always within reach and ready to capture a cute picture of her little Harry) and approached on silent feet. Finger at the ready she shot a 'finite incantatem' and saw the the not so vigilant form of her husband head tilted back in sleep, glasses askew, mouth hanging open and wand in hand appearing from beneath the disillusionment charm as it was ripped away. The picture was equally parts exasperating and cute. Deciding to let James get the rest he seriously seemed to need, when her coming into the room hadn't even stirred him at all, she put her camera away after another quick shot and turned back to Harry who was watching her with his big green eyes blinking through the bars.

"Don't you have a silly daddy, Harry?" she shook her head, smiling at the gurgle she got in response.

Now, Serpentarius knew magical babies were generally more advanced than a muggle baby could ever hope to be - this once he was unbiased in saying that a magical baby was superior to their muggle counterparts in every way - so he wasn't surprised when his mother - it still sent a thrill through him to be able to say so! His Mother... - put him in his high chair and set down a small wooden plate before him and handed him a soft wooden spoon and then started commandeering a small army of house elves. He didn't mean the material of his cutlery (Wizards did not believe in muggle made materials such as plastic) but she did the unforgivable and left a toddler alone with food, a one year old to be exact. Such an act would have caused an outrage in the muggle world, but was perfectly acceptable in the Magical World as; firstly, he was not alone, while he could not see them he could clearly feel the eyes on him and his bet was on Mildry - from her enthusiastic waxing in the future, she had cared for him since the day he was born and had done so to his father before him - and secondly; a magical toddler was well capable of shoveling food into their mouth without choking.

His only problem was he was in no way used to his body yet and was endlessly frustrated by the slow awkward responses of his limbs, so his breakfast/lunch was slow going as he carefully dipped his spoon in the gruel and shakily lifted it to his small mouth. He must have done well enough as he was soon rewarded with small dices of honey melon.

He was content to nibble his food while watching his mother storm in and out of the breakfast room, and staring out the huge glass window to the rain pelting outside and the clouds roiled above, listening to the soft symphony of pitter-patter as the drops hit the pane. Yes that was an British summer and he was infinitely fascinated in seeing the pure life that was everywhere, delighting in every small gap in the clouds that showed glimpses of the brilliant blue sky.

An hour later found the young Potter heir sitting in his flay pen surrounded by toys, as his mum pacing the length of the parlour, muttering darkly under her breath about impertinent late guests not even appreciating her hard work since they were not here.

Yeah.. he was not dealing with that. He had a dad to deal with irate females, he was just the cute little darling son that could do no wrong, especially on his big day... yes, you could bet your arse, he was going to exploit that for all it was worth, but later... when he was in full use of all his limbs.

He was now entertaining himself with rolling and crawling around and working up his nerve to get up on those two unsteady legs.

Ignoring the multitude of toys and instead crawled over to the large golden framed, floor length mirror and examined his new body closely. He had to admit now the excessive cooing from both his parents and any passing house elf made sense; he was cute as a button. With smooth plump cheeks tinted apple red from his exertion, small pouty mouth and the hints of aristocratic cheek bones and jaw made him a beautiful baby coupling that with a cute button nose and downy soft black hair that went ever which way he had a fluffy look about him the final nail on the coffin of any resistance were his eyes; sparkling emerald orbs that seemed to take up half of his face peeked up from under a ebony fringe.

Forget Snow White, it should be illegal for someone in diapers to have such an allure.

He wasn't ashamed to admit that at the first glimpse at the mirror, a coo had escaped his lips before he realised it was himself he was seeing. He was just so glad that his crazy minions where not here to see him like this; he didn't think he would survive the encounter, especially if Hilda got her paws on him, then his parents - or anyone else for that matter - wouldn't see him until he hit puberty.

He would never live it down.

Even aside from the kidnapping risk, it put him in a right pickle; calling himself Serpentarius in that teeny-tiny elfine body was ridiculous.

Serpentarius was a powerful man that had untold seductive power at the tips of his fingers and was capable of seducing and terrifying those in his surroundings simultaneously with a single glance, he was Master of the strongest organisation in existence, war veteran and genius behind the most terrifying concocted poisons and acids.

Serpentarius was the name of a living legend... not someone who wasn't even master of his own bowels and needed assistance keeping himself clean.

While that man might have a chance of rising again in the future, that look at his reflection made one thing perfectly clear; he could not - by all that was holy - be Serpentarius in a dainty body that looked like the worse it could do was give you caries unless he wanted his enemies to laugh themselves to death. That was not him.

He needed a new name.

"Harry?"

His heart fluttered in his tiny chest, and he turned to see his mum smiling softly down at him before crouching and gathering him up in her warm embrace, cuddling him to her soft chest and dropping a kiss upon his crown.

Well it wasn't too bad he supposed. It did have a nice ring to it when his mum said it. He could bear being Harry again as long as that meant he would hear his mother calling his name more often. It sounded so nice from her lips.

"Yes! My little Prongslet's first birthday party!" James exclaimed and scooping his son up and twirling around the room.

"You do realise he has a name?" Lily remarked dryly, not surprised at all when she was ignored in favour of the birthday boy, it was doubtful James even heard her as engrossed as he was in their game, James continued playing with a giggling Harry, delighting in making him squeal.

Sighing Lily looked at the big grandfather clock again and noticed that it was already past two, half an hour past the allocated time. Her fist clenched as her infamous temper reared it's head, they better have a good explanation for their tardiness, she would let nothing ruin her darling son's first birthday. It was for that reason she kept a tight hold on her temper, restraining herself to dark muttering and taking care to censure her words in the presence of the young impressionable ears.

She just didn't understand this. Sure in the muggle world a storm such as this, would have seen a party cancelled but here in the magical world where transportation didn't rely on streets or actually stepping a foot out in the open there was no excuse. Even if it was just to cancel "I get why they didn't send owls in this weather if they wanted to cancel, but

"Ah."

Lily pinned her husband with a penetrating stare as he unobtrusively tried to make way out of the room after that sound of startled realisation. She could smell the guilt from across the room with her senses of seven years in the same house as the Marauders and two years married to one. That green eyes glare framed by crimson was a formidable one and James wanted to keep sharing the bed with his wife so he reluctantly shared his less than stellar actions.

I might have calibrated the wards last night, from war settings to full lockdown. And I might have forgotten to change them back this morning."

"You might?"

He nodded. "Yes, might."

"Meaning?"

"Even if they tried sending an owl after hours of futilely trying to enter via the floo network we wouldn't know because nothing gets through the wards. Unless You-Know-Who and an army of Death Eaters stood outside battering against the wards nothing would."

Lily softened. "Good to know." She rewarded her husband with a kiss, it was wonderful to have a man so intent on his family's well-being.

A second later James gulped at the murderous look his Lily-flower sent him, he knew her reaction was too mild to be true. "Now go and put them back to normal." she ordered sternly. She did not labour and plan for her sons first birthday party to have it all go to waste.

"Yes my Lady!" James saluted and strode out of the room a grin upon his lips.

Once the guests had the option to actually arrive, the party was soon in full swing and adults were milling around he Manors lower level. There were a lot of people but thankfully less than he had feared he was still fascinated by the amount of people his parents knew even if it mostly felt like a meeting of the order of the pheonix who insisted to surround them constantly. Oh if he only had his real body...he would have been able to use his long legs to run away

birthdays as a toddler filled with adults was in one word; boring.

After ten more minutes of it he amended that to very disturbing and uncomfortable with a never-to-be-repeated and avoid-at-all-costs labels. Being a cute toddler had it's downside it seemed as everybody and their grandmother - especially their grandmother - felt the need grab at him and pinch his cheeks. Why?! What did his poor cheeks ever do to them?

They might be a bit chubby with baby fat but that was no reason for abuse. He had just discovered that dimple on his left cheek, he would like to keep it thank-you-very-much.

The only other child he knew was Neville, but he only caught a glimpse of him all he saw was chubby cheek and tuft of dark blond hair as he slept in his Mothers arms, both Longbottoms keeping him close at all times. Thankfully the Weasley horde stayed home except Ginny, who was touted around by Molly who had yet to shut up about the miracle of the first female Weasley born in eight generations. For some reason James bristled at her very presence and thankfully kept him far out of reach of the red heads.

It was boring. He intellectually knew who they were recognising them from his research into the Order of Phoenix past as well as his parents social circle, but seeing the living breathing talking versions was a bit jarring. Especially as he knew some wouldn't even last to see the leaves turn red, like the McKinnons that were gathered at the buffet talking to who he identified as a younger Amelia Bones after a bit of squinting.

Then he came in.

For nothing in the world would he have been able to stop his reaction, as soon as the sight registered in his mind, Harry squealed small arms reaching out to the man instantly and if he hadn't been held securely in his mothers arms he would have pitched forward as his body leant forward.

There he was, wavy black hair stormy eyes that twinkled with happiness and mishief that before he'd only seen small glimpses of but was now so apparent that it made his heart lurch. It was Sirius. Despite his later hoarding, the photographs/pictures did him no justice, they paled compared to the real thing

If he'd thought it was heart wrenching to see his parents again, alive happy and fully solid, it was nothing like the punch in the gut when he saw his godfather for the first time in the flesh after his last glimpse of his shocked face as he disappeared through the Viel.

He couldn't have stopped his reaction if he wanted, his entire focus shifting entirely on the lopsided grin that formed once stormy dancing ones met his own green ones.

"Pa'foo', Pa'foo', Pa'foo'!" Harry babbled not letting his lethargic infantile tongue stop him as he desperately strained his small arms wanting to touch his godfather, feel the warmth and rushing of blood under skin to affirm that he was real, was there, was Alive.

Lily struggled at her sons sudden eagerness, slightly overwhelmed at her contently lethargic son turning into a wriggling wildcat in the blink of an eye and doing his lion onesie proud.

The next moment Harry was free and he felt the rush of air before he collided into a solid chest, where arms automatically embraced him in reflex, kicking his small feet he scrambled until he had his chubby arms wrapped around his neck and his form half hidden by thick shoulder length hair as he pressed his face in the crook of his neck, inhaling deeply while he held on with all the meagre strength his small body could muster. Taking a deep whiff of a scent he had almost completely forgotten, he felt his throat close as his pint-sized body swelled with a barrage of complex feelings causing it to shudder slightly, there was only one person who smelled like this.

The chest underneath him rumbled and a fond chuckle was heard.

"Hello pup. Miss me?" Four simple words had never sounded so wonderful before.

James looked gobsmacked from his wife to his laughing best friend, repeating the circle a few times until he processed what he'd just seen, unable to utter a single word. His wife didn't share the problem. "Did my baby just fly through the room?" Lily asked confused staring at her suddenly empty arms, a hint of steel creeping into her voice at the end.

Sirius barked a laugh that had Harry's chest clench in chocked emotions, as he heard it rumble through his chest then burst free, it was so light and full of mirth, possessing a carefree quality that in the future had been missing.

Unconsciously his grip around Sirius tightened, staring up into those trademark stormy eyes of the Black's alight with a spark of mischievous happiness, he renewed his vow once more; this time he would ensure it wasn't lost. This time he would make sure Sirius wasn't wronged on the accounts of one greedy manipulative old goat.

He will show the world what happened if you touched his precious people, they will see what happens if you dared invoke Serpentarius' wrath, he may be just a toddler named Harry right now but he was still and always will be Sirius' godson, a godson that would use every ounce of his superior intellect and resources at his fingertips to ensure his dogfathers well-being.

May Merlin have mercy on them because he would not. He had a long memory and he wouldn't always stay this small.

But for now, he blissfully relaxed for the first time since the hell under the misnomer of party started and his personal space was invaded for the first time. He snuggled further into the warm embrace, breathing in deeply the familiar complex scent of expensive cologne, fire-whiskey and fur that was just so Sirius, inhaling it with relish.

In the background his father and those others that saw sputtered at that powerful sign of accidental magic. Harry only had ears for Padfoot's infectious laugh, unable to resist the innate joy and joined in.

"That's my pup! It just proves I'm the best godfather of all!" Sirius struck a pose one arm securely supporting Harry even as he laughed gleefully, Harry's tinkling giggles following closely behind, as small fists clenched tightly in black wavy curls.

Here the second chapter with Harry and his parents also the first glimpse of our favourite Marauder the one and only Sirius Black.

Hope you enjoyed it.
