Harry Potter and the Revenge of Atlantis: A Harry Potter Fanfiction

Disclaimer: I do not own Harry Potter or any of its associated characters: all rights belong to JK Rowling. I do not own any crossover references used in the story: all rights belong to their original creators. I do own any OC spells explained at the end of a chapter.

Plot: Harry Snow Response: A friendship betrayed. A child forsaken. A future of harmony, now broken. He was supposed to be the one with the power to restore ancient allegiances. Shame nobody warned him about their egos. Very well, if he can't be a beginning, he'll become the end.

Challenge Information: DZ2's 'Harry Snow' Challenge: Harry James Potter: a name we all know and love. A truth, we have no idea about: Harry might have James' middle name and surname, but he can never...will never become Lord Potter. But that doesn't mean he can't and won't become a Lord ever.

Rules: All affinities are welcome

Non-BWL/WBWL Harry

Harry MUST be the bastard son of James Potter and another woman who isn't Lily

Either way, Harry MUST be born on the same day as Lily and James' child

Who this woman may be is up to you, but after the attack on Godric's Hollow, James 'gives' Harry to his true Mother to raise while he 'helps' his real heir/heiress become all they're meant to be

What happens during the years Harry's with his real Mother is up to you, but he MUST still go to Hogwarts at age 11

Harry MUST also be named the heir of his Mother's family if she has one

Because he's James' 'dirty little secret' James MUST be to Harry like Snape is to him (hateful, resentful, biased, ignorant etc.)

Despite this, Harry builds himself up to be what he chooses to be, whether James, Lily or the Child-Who-Lived likes it or not

If Harry's dark and/or evil, he MUST be out to make his half-sibling be the worst he can be, so it's easy for the Dark to beat them

All pairings are welcome

Chapter 1: It Worked For Pinocchio

'This is right.'

This was the single, borderline-obsessive notion, which was all that James Potter thought to himself as he stood at the edge of the water, his eyes filled with a mixture of self-gratifying pride and personal, if not delusionally-selfish certainty as he looked out at the water, letting his mind focus only on the thought of what he was doing was for the Greater Good.

And it was!

With this, he could be free of the skeleton in his closet, which meant he could focus on what was most-important, namely his son and heir and the great and glorious future that his special little guy would bring.

Besides, who'd miss the little bastard?

Lily had basically blacklisted him since birth, claiming it was a fool's errand to do what they'd done and promise what they'd promised; James – or, more-specifically, James Arthur Potter, aka JJ, as in James Junior – only ever seemed content and comfortable whenever it wasn't in his nursery.

In fact, on more than one occasion, James could have sworn blind that his real boy was shit-yourself-terrified of this little thing.

So…yes, this was all for the Greater Good

As James reassured himself that this was right, he felt bile burning in his throat when he heard a curious, cute-sounding gurgle coming from the blanket-wrapped bundle in his arms, indicating that the little freak was wide awake and, clearly, looking for some attention.

He had to try very hard not to look down at the bright, sea-green eyes – the colour of which had often been mistaken for the colour of his only true love, Lily's beautiful emerald-green eyes – that looked up at him from beneath a small, early-forming mop of wild, scraggly black hair, nor the cute, but naïve look of the little boy who reached up with tiny hands to try and cup James' chin.

"Dada?"

"No!" growled James, shifting the bundle in his arms as he hissed at the now-confused infant within, "Don't you ever call me that, do you hear me, you…you abomination? I am not your Father and you…you are not my son: you…you're a mistake! A dirty, impure thing I had no business raising, even if she did promise me what she did! No: I have only one son and his name is James Arthur Potter…and as for you…well, if she wants you to be the chosen one so bad, she can have you back…do you hear me?"

As he roared out the last part, James let his rage-filled gaze linger on the water as he lifted the bundle to the seas, like he was offering it to some underwater deity that, he hoped, would sooner eat the little abomination rather than spare him.

Suddenly, as though someone was listening to his delusional cries and the emotional drunken highs he'd led himself onto, the seas suddenly grew thick and fierce in the waves, though James had taken precautions, as was evident by the way the waves crashed against his well-formed shielding charm, but didn't wet him in any way.

"Nice try!" sneered James, again ignoring the way the cute boy in the blankets tried to reach for him, seeking the love and warmth that only a Father could give.

Unfortunately, the Father that held him was neither warm, nor loving, "But, I won't raise a bastard to think he can show off to the rest of the world, while my only son is the real chosen one, so you want him? Then you just go ahead and take him, you filthy slut!"

Without so much as a backwards glance, James dropped the bundle onto the water's edge before, aiming his wand at the innocent, vulnerable child, he cast the most-powerful Banishing Charm he could muster, sending the bundle skipping along the surface of the waves like a stone before, inevitably, it sank beneath the waves, leaving James standing alone on the shoreline.

A smug expression greater and more-cruel than cruel could be on his face as he mused, "You thought you could trick me? The man who made tricks what they are? Stupid half-breed witch!"

With that, James Apparated away, leaving nothing but crashing waves and a flash of lightning that suddenly lit up the skies even as he vanished, clearly believing he'd gotten away with the inhuman act he'd just committed.

What a fool he was!

Atlantis

At the same time that the bundle sank beneath the waves, what could only be described as a cry tore through the ebb, flow, tides and currents of the underwater realm. While the surface of the seas frothed and churned like a raging tempest made flesh, beneath the waves, the darkness of the sub-surface world seemed to swallow up the bundle, save for the rippling waves left by the cry.

After what seemed like an age, a thick, dark shadow suddenly rose from the depths, where it proceeded towards the bundle, letting out a low, if not mournful, but also hopeful cry of song.

Hearing the sound, the infant in the bundle – whom should have been gasping for air and drowning, but, instead, seemed amused, if not content by the embrace of the sea – reached out with a tiny hand before he giggled, sending small pillars of air bubbles rising to the surface as the source of the nearby song revealed itself.

A blue whale, Earth's largest mammal and underwater being – well, non-magically speaking, at least – drifted up close and personal to the infant, where it proceeded to brush its silky-soft, but damper-than-damp flesh against the child.

While the small boy laughed and seemed content to pet and fondle the creature, as the bundle reached the whale's head, the great beast suddenly opened its jaws wide, causing a powerful, sucking torrent to grip onto the bundle, pulling it, and its pseudo-human occupant into the mouth of the whale, which then snapped shut behind it, trapping the infant on the whale's large, damp and very smelly tongue.

In any other situation – or, indeed, any other story – the blue whale might have gobbled up the infant like he was nothing, but an appetiser.

But, just as the whale's song spoke of wonder and might, so too had the babe's song spoken of something more to the whale.

Something that told the whale to keep the boy safe in its mouth as it returned the child to where it…he rightfully belonged.

And, if he even thought about swallowing the infant down into its spacious belly, like he was nothing, but a snack to the large and majestic animal, the blue whale would be forever dooming its entire race to the mercy – or lack thereof – of the true Masters of the Sea!

So, for now, the child would be safe inside the whale's mouth.

At least, until he could return to his people…

Atlantis

One Hour Later

Far beneath the waters and the wilds, out of the sight of human eyes and those who didn't know any better about what really lay beneath – nor did they have any actual business knowing about the denizens of the deep – within a very beautiful, picturesque palace that was like something carved and crafted by the Gods themselves, a fair-haired lady with the clearest shade of moonlight-esque-silvery-blue in her eyes that had ever been seen suddenly snapped her head up when she heard a commotion coming from outside the door to her throne room.

Rising from a pearlescent-white throne that looked like it had been carved from the aforementioned precious stone – meaning pearls – the woman walked towards the doors, just in time to see them open with a bang that seemed to echo throughout the depths of the ocean itself.

"My Lady!"

To her surprise, the owner of the voice was a well-aged man with silver-fox-grey hair and eyes that were the coolest, but sternest shade of brown she'd ever seen. Like many other prominent members of her court, as well as the elites of her realm, he wore a sapphire-blue suit, the finery of which was emphasised by many badges and marks of office, as well as a silver pendant bearing the coat of arms of the palace – a trident and a bolt of lightning mounted on a diamond-shaped shield bearing a banner depicting the name of the kingdom: Atlantis – and had a look of fear and fury in his eyes as he struggled to get past the guards, whom were keeping him at length with their own tridents.

However, when the fair lady emerged from the throne room, the guards eased their offensive threats and, instead, saluted the female as she told them, "That's enough. You can let him through: Vulko, this is a surprise. What brings you to my halls this late in the night?"

"My apologies, my Queen, but I have just received word that our scouts have just reported a terrible discovery," replied Vulko, his voice as aged as his looks, but this also showed his strength, as did the air of youth and warning in his looks, as he explained, "It seems a certain emissary decided to forsake his gift from our domain, in favour of a newfound fame!"

Suddenly, even the guards protecting the throne room shuddered when an ominous clap of thunder filled the air, accompanied by a tremor that shook the entire palace to its foundations.

Over their heads, a bluish-coloured chandelier suddenly dimmed in its glow, casting long dark shadows along the walls and ceilings while, as Vulko saw and heard this mystical event taking place, he also gulped when he heard a bass rumble of a female voice address him from the woman who he'd come to meet.

"What has he done?"

"I…I would suggest that you…you come…come and see, Your Majesty," replied Vulko, leading the woman – whom was known to the people of Atlantis as Queen Ariel Atlanna – away from the throne room, with no small amount of speed, haste and urgency evident in his movements, even when, at one point, the queen barged past him as she raced towards the room he had been leading her towards.

As the doors to the new chamber – also known as one of the healing chambers of Atlantis – flew open, as though to receive her, the queen saw a few variously-aged, white-robed Atlanteans gathered around a single white crib, in which, a single baby boy lay, dressed in nothing but a single one-piece outfit.

He had the brightest, sweetest-looking sea-green eyes anyone had ever seen while, atop his head, he had a small mop of black hair that appeared to have sprinkling of fair-blond colouring, much like that of the queen herself.

However, the fact he was there at all alarmed the queen more than anything else.

However, when she saw one of the Atlanteans suddenly hurrying to project what could only be described as a pale-blue aura from their hands into the body of the child, she was instantly on alert. "What are you doing to him?"

"Performing a powerful, and, sadly, necessary Cleansing Wave upon him," replied the healer.

She was an auburn-haired female with a similar shade of clear-blue in her eyes to the Queen herself – in fact, were it not for the darker hair colour of the healer, anyone would mistake them for twins – though, right now, those eyes were fixed on the child before her as she explained, "You see, my Queen: apart from the presence of the disgusting tang of surface pollution left by the touch of the ungrateful surface-dweller's magic, it seems there is also a taint lurking within the mark on his forehead."

"A…a…what do you mean a…a taint?" asked Ariel, moving to stand next to the healer in question before she watched as the blue energy from the healer's hand seemed to reach into a furious-red-coloured mark on the infant's forehead, which was shaped like a bolt of lightning.

As she observed the power at work, Ariel looked to the healer as she asked, "Can you identify the taint, Amphitrite?"

"Yes," hissed Amphitrite, her voice as cold as ice while her eyes hardened in their sockets as she growled, "I mean, I've only read about them, of course, but I never would have guessed any magus would be desperate enough to use them!"

"What is it?" asked Ariel, though, as she did so, her eyes widened with horror when a shrill, nerve-jarring scream suddenly filled the healing room.

Snapping her attention to the child in the crib, Ariel watched as what could only be described as a black ooze was dragged out of the scar on the boy's forehead, the ooze itself being the source of the scream. However, as Amphitrite's blue energy wrapped itself around the essence that was being forcibly pulled out of the little boy's lightning-bolt-shaped mark, the scream started to lessen, only to be replaced by a warm, ethereal humming, like the world's most-beautiful whale song.

As Ariel watched with bated breath, she saw the blue energy close in around the ooze, like the jaws of a great beast chomping down on its prey, before, with a sound like the sudden collision of tempestuous waves crashing against the shore, the energy obliterated the ooze, though the effort left Amphitrite pale, sweaty and gasping with intense levels of exhaustion.

"There…it…it's done…" gasped Amphitrite, dismissing the other healers before, wiping her brow with the sleeve of her robe, she turned to Ariel as she asked, "So…I suppose the question now is: what, exactly, is my nephew…your son…doing down here in the first place, Ariel?"

"I…I don't know," replied Ariel, looking into the crib.

To her relief, the little boy was fast asleep, clearly having been drained himself by the exertion of the power Amphitrite had used on him.

As she breathed out a sigh of relief that she hadn't noticed she was holding in, Ariel's eyes darkened just slightly as she explained, "According to the terms of our arrangement with the surface, my son…my beloved little Harrison…he was meant to have been raised among the surface-dwellers: as a gift and a test for them, to see if the time was, indeed, right for us to return our ancient gifts to them."

"And you?" asked Amphitrite, a note of amused curiosity in her voice as she asked, "What? Were you just going to be…like, what? A distant relative or something, Ariel? This is your son, after all: he has been born of both Atlantis Royal Blood and the magical bloodlines of the Surface World, so, tell me: were you actually going to neglect him or something?"

"I would have visited him, if only to guide him through his powers," explained Ariel, though there was a note of anger in her voice as she added, "I don't understand, Amphitrite: how could any Father abandon their own child like this? And so…so willingly? This would never happen had I gone with tradition and chosen an Atlantean to give me my child!"

"And yet, you were determined because of what Kamdor told you," argued Amphitrite, a note of pity and mutual respect and understanding lacing her words as she told Ariel. "You heard that your child would be a great and powerful force, whom would go on to become the greatest ruler of the Seven Seas since King Poseidon himself and you chose to believe the part about requiring a force beyond the Kingdom's borders…despite my own words of advice and Kamdor's warning about there being repercussions that you had to be ready for."

"I…I thought it would…he might need…"

"I am sorry, sister," sighed Amphitrite, looking from Ariel to the child in the crib as she told her, "However, this does present us with an opportunity."

"How?"

"Well," replied Amphitrite, looking from the child in the crib, to her sister once again as she explained, "Look at it this way: the last son of one of the last Surface Dwellers to earn favour with the Kingdom has chosen to spit in our faces and try and believe himself to be untouchable. However, I'm sure it goes without saying that the rites you used to impregnate yourself with his seed, willingly, as he seems to have forgotten: they have given us an opportunity to make him wish he'd never done this…even though it will mean waiting ten years, give or take, before we get the chance to start that opportunity."

Suddenly, it was like a light bulb had been switched on in Ariel's mind, "You…you mean…"

"They may not be ready for us, dear Queen and sister," said Amphitrite, clasping Ariel's hand before she smiled wolfishly, as did Ariel, as they looked down at the sleeping form of the child whom would have come to be known as Harry James Potter – though he was really named Harrison Poseidon Atlanson-Peverell to give him his full name – as Amphitrite finished her thought.

"But what they should be asking themselves now is: will they be ready for him?"

So, the adventure begins and, wow, talk about a stroke of sheer dumb luck: thanks to a whale of a coincidence – puns fully intended, I assure you – Harry now finds himself facing a life fit for…well, him, I suppose, but what will this life do to him?

Also, how might the Boy of Two Worlds exact justice swifter than the rush of the Seven Seas on his betrayers?

And…hmm…you don't suppose Harry might ever remember being swallowed by a whale, do you? Hope this doesn't make him weird or nothing…well…then again, it is Harry, am I right?
