The mountain was gone. Godzilla stood overlooking its remains and the other kaiju had ceased tearing into their meal's remains to look at what had happened and beheld a horrific sight.

With a terrible wail the darkness surged out of the crater in a black tide that carried Godzilla down the crater's slopes and back to his allies. Surviving quintapeds shrieked in fear and fled from the horror that reigned over their island now, diving into the sea in a suicidal frenzy born of sheer terror.

As the shadows climbed toward the sky, the kaiju of Monster Island bellowed their challenges. They would not suffer the abominable night to live, and began to march toward the crater's edge once again. A black tendril extended from the main body and slammed against the landscape with terrible force, shattering the land and opening a deep crevasse in the bedrock. The earth trembled from the impact and even the kaiju stumbled but they persevered. They sensed the dark power keeping this unnatural enemy alive, pulsing like a heart in the crater.

Several strands of the Uber Obscurus surged outward, pointed like colossal javelins, but they were halted by atomic ray, the shaft of light dispelling the dark if only for a moment.

Rodan and Mothra flew towards the crater from opposite sides in an effort to confuse the Obscurus with a flanking maneuver, but the strange hybrid of Yog and Voldemort was not so easily fooled. A great shadow welled up and swung at Mothra knocking her from the sky, and another abyssal tendril lashed out at Rodan who banked hard to evade it.

Once more the face of Voldemort appeared, this time directly in the path of the earthbound monsters, and with a terrible scream it vomited Fiendfyre. The monsters cried out in agony as the unnatural fire clung to their skin and even shaped itself into hideous parodies of themselves, biting and scratching at them with flaming limbs. Only Godzilla, born in the fires of a nuclear weapon, was able to endure the pain and continue forward, his wrath growing with every second.

He was struck in the side by another black tentacle and nearly stumbled, but blasted it back, and continued his march up to the crater rim. There in the swirling mass of shadows was faintly glowing teal object - the manifestation of Yog and the body he possessed.

Sensing what would come next the darkness and Fiendfyre retreated in an effort to shield their creator, all surrounding that single point in a singularity of magical might before launching at Godzilla to intercept his atomic breath.

The world watched in horrified awe as the blue beam beat back the shadow and fire until with a final lugubrious howl the Obscurus was no more. Voldemort and Yog were gone. The magical night gave way to the daylight and Godzilla led his fellow monsters in a chorus of victorious roaring.

Far away, in an office observing the battle carefully, Harry and his friends whooped and hollered as the battle was won, but then…

"Son of a bitch, you've got to be kidding me!"

The adults in the room were clustered around what Harry had begun to derisively call "the snowglobe of doom" - the crystalline ball that held the prophecy that had dominated so much of his life.

A few of them continued to curse, but Professor Arachtocril showed Harry the clear white orb and explained. "If Voldemort had been truly defeated, the ball would've turned black and become inert. As you can see, it hasn't. Voldemort is still alive somehow, which means your life is not yet truly your own. I'm sorry Harry, but this truly does seem to be your battle to fight. All we can do now is train you and hope for the best."

1995

Time passed, and Harry and his friends grew in skill and power under the tutelage of competent teachers who understood the stakes at hand, but there were others at work who were far less benevolent.

Albus Dumbledore had fallen far in the years since he'd fled Hogwarts. He'd watched his carefully laid plans come to ruin and exposure, and the public not only no longer saw him as a saint, but openly called him a Dark Lord for attempting to condition the boy into being a weapon of questionable sanity. Arguably worse for his state of mind, he'd spent the years on the run with no one but Severus Snape for company, the bitter man's ranting ever quick to blame Potter for their predicament.

And that was why they were here. It had been easy enough to find the shack containing the Riddle family ring. He'd still almost put it on, but Severus had stopped him, not recognizing what the stone truly was and simply thinking him mad for trying to put it on. But no matter. With the horcrux they could summon Tom's broken spirit, and with the captive they had they could embody him.

Bone of the father, flesh of the servant, and blood of the enemy — a bit of dark magic most foul, but the easiest ritual to embody a shade. Naturally, Severus played the servant. Dumbledore had no intention of sharing flesh with Tom — that and that alone in his view would muddy the waters of prophecy.

Not long after Severus drank a potion to regenerate his hand, and Tom Marvolo Riddle found himself with Dumbledore's wand pointed at him. He had a plan, and they were going to stick to it, Tom's pride be damned.

Perhaps his defeat by the Godzilla creature had shaken him more than he cared to admit, because Dumbledore noted that Tom fought far less than expected.

In the dead of night they broke into Ollivander's shop and Tom retrieved a wand from the back room — something that used cherry wood and an exotic scale — then Tom used it to make a portkey to Japan.

Once there, they found the Xian embassy and cast the Imperius curse upon one of the hapless employees. Albus had very specific instructions for the alien: he was to take them to another world that coveted the Earth, and from there they were to build a new force with which to retake the planet. Much of civilization would have to be destroyed to set things right, so it had to be an especially inimical alien race.

"There is one that fits your criteria, my Lord," the controlled Xian explained as he piloted the ship. "The Kilaaks that live on an asteroid between Mars and Jupiter."

The Xians and the Kilaaks were no allies, the ship receiving a cool reception until Fawkes sang a song and Albus explained their presence over the speaker. At that point the Kilaaks manifested humanoid forms and welcomed them, offering them special garb to survive their atmosphere and conditions.

There Albus beheld their key to conquering the Earth: King Ghidorah, tranquilized, pacified, and under Kilaak control.

While Albus and Severus were in awe, Voldemort decided that the time had come to break the metaphorical shackles Dumbledore had him in with the tools provided. With a simple curse he killed the Xian and tore his soul asunder again, making Ghidorah his new horcrux!

The additional voice in his head was enough to rouse the hydra, who cackled as the horcrux seemed to cancel out the mind control of the Kilaaks. Still, the new voice sought to command him, but this one was weak, and Ghidorah lashed out.

Voldemort let out a scream of psychic agony but even as he collapsed issued a final command: to kill Dumbledore.

Ghidorah resented the orders, but requests to kill were always obliged. He turned to look at the long-bearded man and and opened fire.

Dumbledore disapparated back to the ship at that instant, but Fawkes was not so swift, and the gravity beam atomized him, leaving no ash from which to respawn.

1999

The Kilaak invasion was in full swing, and the mind-controlled monsters were running amok across the world… but things were not so dire as what they might have been.

In the years since reintegration had begun, the magical world had started to see the nonmagical in a new light as it had improved most of their lives. Now the time had come to return the favor.

Magically hidden bunkers were comparatively safe from the kaiju attacks, and many magical folk brought in their nonmagical counterparts in an effort to save them. Destroyed infrastructure could be swiftly repaired with waves of wands to allow emergency services to get where they were needed. Portkeys allowed for mass evacuations from major cities to areas less well trod by giant feet.

But the world would not submit to the alien invaders, and soon — albeit far too late for many — the Moonlight SY-3 found the Kilaak control device, and used it to sic the kaiju on their masters at Mount Fuji. But as the monsters of Earth fought King Ghidorah, a small group entered the Kilaak base through a hidden path, to put an end to the masterminds once and for all…

As enchanted frost tore the entrance asunder and reverted her guards to their vermiform shapes, the Kilaak Queen fled, not willing to test the effectiveness of her shield against arcane ice, leaving her three earthly advisers to face this unexpected threat.

Snape, Dumbledore, and Voldemort raised their wands in readiness.

With a bright flash the ice exploded toward them, but their shield charms held against the shrapnel. They aimed their wands at the entrance, confident that whoever was coming through would ultimately be killed once they set foot in the doorway.

As such, they were caught off guard when nothing seemed to come through. Tom and Albus both looked to Severus. As the weakest of them, he was the most expendable; murmuring about Potter, he stepped forward.

Right onto an invisible trap.

He was just barely able to shield himself in time to prevent being showered in a powerful acid, and as he did so the wall beside his "allies" exploded, and a quartet they did not expect came through: Luna Lovegood, Hermione Granger, Neville Longbottom, and Harry Potter.

"POTTER!" Snape screamed, about to attack him only to be forced to block a spell from Neville.

"Not today Snivellus." Neville taunted, and the man's hated nickname sent him into a frenzy.

Voldemort raised his wand and managed to say, "Avada—" before his mouth was suddenly sewn shut and his arm forcibly moved to point to the ground, as Luna and Hermione both wordlessly cast spells of their own on him.

Dumbledore was just barely able to deflect a powerful silver spell from Harry, and that deeply shocked him. That was one of his spells, how did Harry learn it?

Snape attempted to set Longbottom on fire, but nothing happened. He couldn't stop himself from blurting, "HOW!?" Even as he blocked another spell.

Neville smiled vindictively at him and said, "There are a lot of things I can do with potions since I had a competent teacher," he paused to deflect a dark curse, "who wasn't caught up in childhood grudges," he blocked another, "and who wasn't responsible for my parents torture."

"IMPUDENT BRAT!"

"I'm the brat? Let's see, you couldn't get a date from Lily Potter, so you ran to snake-face with a prophecy from a drunken loon. Then when he believed it against all odds, you didn't like that he was going to kill the woman you'd been obsessing over since childhood, so you tried to make him target my family. And then when nothing worked out for you because, shocker, Dark Lords don't keep promises, you decided to take it out on Harry and me in the most petty of ways. Maybe I'm a brat, but at least I'm not a deluded dark nut like you."

Snape bellowed in incoherent rage and started casting the deadliest spells he could — the Unforgiveables, Sectumsempra, and many, many more.

Just as Neville had planned.

With Snape so unfocused, he didn't notice when one of Neville's pockets seemingly opened on its own accord, and he certainly didn't see anything scurry out.

The invisible spider grenade scuttled toward Snape even as Neville backed up, feigning just barely being able to keep up with Snape's frenzied casting, until the grenade scurried up the delusional man's robe to just behind his head and detonated.

Snape screamed as bottled lightning fried him internally, causing him to drop his wand in agony. Not a sadist despite everything Snape had done to him and his friends, Neville pulled out his gun and put the man out of his misery, then moved to help Harry.

Luna and Hermione were keeping Voldemort busy. If the prophecy was true only Harry could truly put him down, but part of the training that had led them to this moment and plan was the knowledge that there were so many fates worse than simple death. Sewing his mouth shut was merely the beginning.

Luna specialized in countercurses and unorthodox uses of household spells, such as using a needle spell to sew someone's mouth shut, and a food coloring spell to color their eyeball's lenses black (as she did now) to blind them, but Hermione's specialization was in horrific use of esoteric and experimental magic. Voldemort could hardly raise his wand to cast at them with his personal gravity increased, and even if his muscles had the strength, there was no way for them to raise themselves with his sudden rapid-onset osteoporosis.

Voldemort, in pain, immobilized, and with every bone broken by his own weight, was surprised and horrified when his wand seemed to leap from his hand and begin slithering away. As were the women.

Unbeknownst to all, the Manda wand prized power and its creative use over all else, and with a will of its own, it now paused before one of its more worthy wielders: Hermione and Luna.

Meanwhile the battle between Harry and Dumbledore was making the cavern tremble - or perhaps that was the kaiju outside?

"All you had to do was die out of love for your fellow wizards! Why could you not accept your fate!?" Dumbledore shouted, desperation finally cutting away all the false eloquence. "It would have given the entire wizarding world your mother's protection!"

Harry growled back, "You wanted to puppeteer my fate from the moment you heard that damn prophecy. Why can't you admit that all you wanted was control? I was a grand experiment to see if you could 'save' your bigoted world without the hard work of confronting pureblood supremacy and Slytherin's habit of churning out dark witches and wizards."

"And so you destroyed our culture!" Dumbledore snarled back, "You made us rejoin the muggles regardless of our own wishes!"

"Is that what this is all about? Not wanting to be part of the muggle world? Wanting to stay a backward culture with house elf slaves and nepotistic leaders?"

"You were one child! One! My plan would have saved hundreds, perhaps thousands of lives! So many bloodlines have been lost because you simply refused to be controlled!"

"Damn right they were — bigoted bloodlines with rich histories of rape, murder, and torture of people who had no ability to defend themselves because their memories of any bad things were erased! I'm proud that I wasn't your puppet! I'm happy that I destroyed your plans!"

"Then you are as Dark as I feared you were becoming, no matter how the public sees me now!"

Dumbledore fired a dark silver spell, and Harry launched a golden one surrounded by glittering moths. The spells collided and fused into a single shining orb which then hurled itself at Dumbledore and broke his body. The shock killed him instantly.

Harry then turned to see his friends looking at him in awe, and he scanned them for injuries. Shockingly, there were hardly any. Hermione and Luna stepped away from the downed Dark Lord for Harry to fulfill his destiny.

Voldemort glared up at him full of hate, and Harry strangely found himself filled with pity. Voldemort had been a hate-filled monster from childhood, but in a strange way he'd been manipulated as well. He'd wanted to get out of the orphanage and been denied because of tradition. He'd wanted to become something great in a world where his heritage denied him that. And he'd wanted to live when a prophecy said he would die. Harry took a deep breath and immolated the last monster of his past.

No sooner was the Dark Lord ash than the cavern began to shake. Everyone pulled out their brooms and began flying toward the exit — now marked by where Godzilla's foot had penetrated the Kilaak barrier!

The quartet flew out beside Godzilla's leg and beheld the aftermath of the battle with Ghidorah. The cosmic hydra was dying, and only its central head was still trying to escape. Minya exhaled an atomic smoke ring, and such was the head's weakness that that was enough to kill it.

Unknown to all present, that was not merely the death of King Ghidorah, but the final death of Lord Voldemort as well — finally killed by the weakest of kaiju.

It took time, but the world recovered. The kaiju returned to Monster Island where they lived in peace. The magical and nonmagical worlds moved forward into a new millennium. Harry was occasionally called upon as the poster boy for coexistence between the magical, muggle, and monstrous worlds, but he was mostly left alone, allowed to settle into a happy life with Luna traveling the world to hunt for her strange and mysterious creatures. And so the story of Harry Potter, the world's first and only adoptive kaiju, comes to a close.

Author's Note: We've come to it at last. The grand finale. It's been a wild ride on this side of the Internet. I know I made some promises I didn't keep, and some things were less relevant than were probably expected, but all good things — and mediocre things for that matter — must come to an end. I bid you all adieu my faceless online friends.
