There are two truths that have changed and will change two worlds.

One. On July 1, 1948 a team of wizards left for Antarctica from Great Britain. A rising star of much potential, Tom Riddle, accompanied them, thanks in part to the influence of the then Headmaster of Hogwarts. They were going to investigate a magical anomaly that many boasted would change the face of the world. After years of no contact from the team, only Tom Riddle returned the sole survivor. The anomaly was left alone, deemed too dangerous to approach.

Two. On October 31, 2001, the night Voldemort fell to a rebounded killing-curse, Second Impact melted the continent of Antarctica and sent the muggle world spiraling into disaster.

Harry Potter: Fourth Child

Prologue: Uncovering a Secret

The beast had been unleashed. With fervor and glory it had reigned its rage against its alien and inhuman foe, and his son had been the impetus he had known the weak-willed child would be. All the boy had to do was sit in the seat and the beast would do the rest. Once the generals of the JSSDF had seen the futility of man-based weaponry, they had turned the reins over him and his organization. The end had been fated, but the players had to go through their roles.

Currently, he was walking down a bright-lit corridor. In the start of the Angel's attack there had been an anomaly.

It was that distraction that had him walking in this direction. He had initially relegated the study of it to the science wing, but Dr. Akagi had quickly taken over the project with only a few sentences to her reasoning. The lack of substance behind her report was irksome, and the reason behind his visit. He did not entirely trust the repairs to Unit 01 in Maya Ibuki's hands. However, he was smart enough to hear his top scientist out before condemning her.

Featureless hallways gave way to the medical ward, with electronic screens next to doors showing the vitals of the patients within. Gendo ignored them as he passed. They entered a wide viewing room, with the left dominated by a window looking out into the vastness of the geofront. There, garbed in white hospital gown and lost expression, was Shinji Ikari. Gendo paused in his gait as his son turned and met his passive glare.

For a moment the two exchanged nothing but silence, Gendo's steady pace taking him away. Shinji's eyes narrowed briefly before turning away to once more gaze out the window. Gendo gave the incident little notice save a thought. So unlike me. In those words were wrapped both condemnation and disappointment.

He eventually reached his destination. Gendo went to stand beside Dr. Akagi, who was bent over a desk reviewing a screen bearing numbers and graphs. He recognized several of the comparisons she was running, some he and his wife had spear-headed; though she was always better at the sciences than he.

He mused that Dr. Akagi must have ordered the desk and monitor to be installed into the hospital room. He glanced briefly to the child laying in the bed across the room, but pulled his attention away.

He stood in quiet silence, knowing what his presence here would do to her. Briefly, he examined her; bottle-blonde hair to contrast against her mother, lipstick artfully done, skirt to the knees with a labcoat thrown haphazardly on. The only thing missing was a burning cigarette from her mouth, but those were not allowed in the hospital wing.

She brought a hand through her hair and sighed. Biting her lip she glanced to him and keyed a quick sequence into the keyboard. A video came to life, depicting the rundown area where the third angel had first penetrated the city. Most of the displays in the area were warning people to evacuate and seek shelter, which most of the residents had done. Save for a single, out of place group of people frantically running down the street.

They looked to a family of foreigners, the patriarch red in the face from yelling. Trailing him was a bone-thin woman with a large teen gripping her hand, looking wildly about in terror. Keeping pace with them was a bedraggled teen, his own face set in hard lines. There was a long thin stick gripped in his hand. They all looked up and froze. Gendo knew what they were seeing and could see the fear wash over them.

The woman screamed and her child fell to his knees, each pointing in horror at something looming over them. The large man tried to cover them and the bedraggled teen raised the stick and spoke, though the audio was not working at the time. A flash of red light shot from the stick, only to collide with a field materializing in the air. It was a clear and hexagonal, but it stopped the light-effect dead, much to the teens shock. Another was launched and it too fizzled against the AT field of the third Angel.

Then the Angel's spindly bone-like appendage came into view, reaching for the teen. The dark-haired child bolted, panic setting his feet in motion. The angel's hand pursued, and another light was launched from the stick. It was at first a pale light that coalesced into a ghost-like deer. Head heavy with antlers it darted for the angel's hand. It struck the AT field and for a moment the hand paused, the deer bowed its head and strained, the field beginning to bulge. All the while the teen ran down the street.

Then the hand closed around the apparition and destroyed it, then taking the same hand it swiped at the teen, sending him sprawling through a shop's window. It took another step forward, but explosions above distracted it, unseen from the angle of the camera. Gendo assumed twin rockets had been delivered by the JSSDF forces at the time. The angel responded and more explosions rent the air. From there the enemy renewed its course for Tokyo-3. The camera showed the family, unperturbed by the angel, rising and looking over to where their fourth member had been injured. They hesitated for only a second before the large man lead them away. The woman waited a moment longer, but the pleas of her child pulled her away.

The monitor returned to the numbers and graphs, their meaning now more clear. Originally, the anomaly had been an errant AT field against the Angel's, shown from the Magi, during the battle. Gendo had recalled how its direct march on Tokyo-3 had been disrupted and it had instead approached along a curve. Odd at the time, but the Angel's penchant for evolving in combat had explained the behavior away. Now this showed something far more puzzling.

"How did you come by this?"

Dr. Akagi blew out a breath. "Three hours ago, and it was by coincidence." Her fingers went to remove a nonexistent cigarette from her mouth. Grasping air she frowned. "Hyuga was going on about an odd video capture Section-2 was editing out from that district as I was working on the repair schedule for Unit 01. At the time Maya was following up on the errant AT field and put the locations together. After what I saw, I took over."

"I see." For a long moment he paused in thought, dwelling upon the strangeness of the video and the comparison of the graphs. Somehow that child had produced an AT field. "And the angel's change in path?"

Dr. Akagi keyed in a few commands and the screen changed to show the trajectory of the Angel. Once out of the ocean it had wondered the beaches for a few hours before suddenly turning towards Tokyo-3. Its path had been a straight line, even when fighting the defense forces. Then suddenly it changed the path to walk into the district. Had it changed its path to search out the child? "It was after the child?"

Dr. Akagi shrugged. "That's what it looks like, but there's no supporting evidence; just our observations."

Together they glanced behind and saw the child from the video laying on the hospital bed with an IV running from his arm. He was bandaged and sedated, but what stood-out was a lightning-bolt shaped scar at the center of his forehead. Gendo frowned.

"You had him transferred?" She nodded. "Keep him under. Have you found the object he was using?" Again she nodded.

"I had Section-2 comb the area and they found it. I've got it locked down and being examined."

"Anything yet?" She shook her head and he frowned. The question before him was; was the object the source of the errant field or was the child? "Keep them separated until we know more." She nodded, but frowned at the next words from his mouth. "And I want you back on schedule with Unit 01 and 00. This is no more a distraction from your real duties, and I don't want you shifting priorities on something that is nothing more than a curiosity."

Her left eye ticked. "We have a possible naturally occurring angel-hybrid and you think it nothing more than a curiosity?"

His face became severe. "Compared to the keys we already possess and the time table now being shorter than we thought? Yes." His response was cold. "If you feel this can yield something viable, set a team on it. I am not dismissing the possibilities, but we both know where your priorities lay."

She took a calming breath. "You can't see the potential? Even against…" She let the thought trail, not wishing to invoke their name.

Gendo's brow furrowed. They possessed Adam while he possessed Lilith. Yet, he controlled the scenario so long as he sat at the head of Nerv.

"I'll look into it." Was all he said before turning to leave. Her voice gave him pause at the doorway.

"Will you be home tonight?" she asked hopeful.

He gave her a final glance, imagining the curves beneath her clothing. He parted from her presence without further word, much to her disappointment.

Time passed and progress was made.

Harry Potter slowly shook the grogginess from his eyes, only to see the world around him tinted orange. He looked around and found himself encased in a glass cylinder, in which he was floating naked. Shame came to him as he went to cover his privates, but panic followed in its wake when he realized he was submerged. Wildly, he clutched his throat and held his breath.

A voice filled the thick liquid, annoyance prevalent. "You can breathe it. It puts oxygen directly into your lungs." The English was stilted and he caught an odd accent, foreign if he was correct.

He followed their advice and tried a few breaths, much to his relief. Shame returned and he covered his privates, realizing belatedly the voice belonged to a woman. She responded with humor touching her tone.

"I've seen it all before." Despite her reassurance he did remove his hands.

The crisis dealt with, he took the time to peer outside the glass and look to his surroundings. The room was small and sparsely lit. Shadows hung along the walls and the light that did exist came directly from where he floated and from various screens showing incomprehensible numbers and graphs. The lady who had spoken, the only one in the room that he could see at the moment, was bent over a terminal with a microphone not far from her mouth.

"Okay, I'm going to ask you a few questions and I want you to answer them as best you can."

"Uh…okay." He tested his voice, surprised it worked in the odd liquid.

"Your name is Harry James Potter and you're a wizard attending a magical school called Hogwarts?"

Harry's eyes shot open and he looked around stricken. It was obvious from his surroundings she was a muggle. Could reveal to her what he was? What about the Statute of Secrecy? "Uh…" he floundered, trying to buy himself more time.

"Confirmed." Came her amused voice.

"I-I didn't say that."

She turned away from her screen. "No, but your body did." She chuckled and typed a few keys with a speed that surprised the teen.

"You also possess a wand and use it to cast spells?"

Again Harry was stuck on how to respond, now wondering just how much she knew. "I can't answer that!" He called. It was then that his full faculties returned to him, he had not noticed how dulled his senses had been. Anger began to grow in his bosom.

"You've confirmed what I wanted to know, so I finished flushing the sedatives from the tank. Do you notice a difference?"

She had intentionally kept him drugged so he to keep his mind muddled; the thought was less than pleasing. "Let me out of here!" He hollered, forgetting his shame and banging his fists against the thick glass tube. It was useless. He yearned for his wand.

"Fascinating," she said in a low voice, "it's resonating with your emotions."

She pressed a key and a portion of the room was lit, revealing a metal podium in which his holly-and-phoenix-feather wand rested. It sat apparently on air, completeing horizontal, slowly revolving while multi-hued lights played across its surface.

Harry's stomach leaped into his throat. It was so close, but just out of reach.

"A whole world we knew nothing about. Yet, there has to be a connection with Lilith. All humans come from her, but he…" Her voice was vague, as if she were speaking more to herself. Was she referring to him?

"Huh…what's going on?" His eye refused to leave the wand. She ignored him as an instrument was lowered from the ceiling, its point aimed at his wand.

"Hey!" he yelled. A bright light was emitted from the point, but it never struck his wand. Instead, coming to life around it was a hexagonal field, one that shook a memory free within Harry.

The Dursley's had promised Dudley a trip anywhere in the world if he came back with good grades, and after watching the latest kong-fu movie, he had insisted on Japan. While seeing the sights of the city it had come under attack and everyone had fled, save for them who could not read the foreign symbols. Then that monstrosity had attacked and he had been knocked into the building. Was he still in Japan? He squinted at the lady, but could not see her facial features.

"Yes, there is the link. The AT field is linked to the soul the way their own," she chuckled, "magic seems to be."

Her console chirped and a quiet, yet demanding voice broke the odd woman's thoughts. "Dr. Akagi, I've met with the council and they have…altered our resources. Have you tested him yet for viability with Lilith?"

The woman sighed. "Negative on that end."

"Good. We already have a replacement should my son fail."

Harry could hear a frown in the woman's voice. "Rei's results are not equal to your sons." Was the woman mad at this Shinji or Rei?

"Thus why she is a replacement if need be." The man's tone had turned harsh, a reprimand hidden behind his words.

The doctor looked down a moment before responding in a quiet voice. She almost sounded afraid. "There's been odd resonances with his patterns. More akin to Adam." There was a long pause, in which the air grew still. The woman fidgeted.

"This alters the plans. Is it on level with Rei's field?" The doctor sighed with relief.

"No, not even close. But…if there is a match, he could become more than an oddity. Perhaps…" She was cut-off.

"Steps would have to be taken. We don't have the resources for that, given his disposition, but the others of his kind may."

The doctor gasped and whirled around, her eyes going wide when she saw who had been listening to her conversation.

Harry quickly banged on the glass as she pressed a few keys. In a matter of moments his eyes grew heavy and darkness greeted him.

Over the course of some unknown time he would awaken several times and each would leave him taxed and tired, drained from the questions and from his protests; which were always ignored. What stuck out most from those frightening times were the woman's eyes, always seeing him as a specimen and never a boy. He yearned to return to Hogwarts and his friends, yearned to grasp his wand and escape, but those wishes were like fish in a desert; leaving him barren and listless inside.

She stood in a corner, quiet and unobtrusive, uninterested in the scene that was unfolding before her. The only task she had been given was one of emergence; if the gentleman that had been escorted proved volatile. With ruby eyes she glanced at the scene and frowned. He was becoming irate with the Commander bearing down on him, even though the man in the robes was a bit taller. That was just how the Commander was, all eventually bowed to his whims.

"I didn't sign up for this!" Cried the man, his hands pallid and pale. His back hit the wall and he tried to wave his arms, a useless gesture and one ignored by the man before him.

The Commander stood five-nine with brown hair and a cropped patch of hair hanging from his chin. His blue eyes were hidden behind orange tinted glasses and his hands were hidden behind white gloves; much of the man was hidden, even from those closest to him. Flanking the imposing figure were two stocky men in black suits and ties. Their hands were currently resting on guns tucked inside their jackets. One had a hand to his ear and was speaking in a low voice, describing the unfolding scene to his fellow Section-2 agents outside the building and room.

None of them were taking any chances this far outside Lilith's safety.

To the young girl's right was a hospital bed where lay a teen her age with black hair. He was sedated at the moment and Dr. Akagi was hovering over him, a needled poised to enter his arm. She was only waiting for orders from the Commander. For a moment the doctor glanced to her and frowned, Rei waited for the woman to look away before returning her attention to the distraught stranger.

Currently, the Commander was speaking. "You were sent for this purpose, the boy's age is irrelevant to your task."

"Are you sick?" the man in robes cried, pointing to the boy in the bed. "He's a child! I don't know what'll do to his mind. He's not even fully developed!"

The Commander glanced to the child for a moment and Rei could see him weighing the options in his mind. He turned back to the man. "You have cast this spell on children before?"

"Yes, but nothing as extensive as what you're asking." He tried to sound reasonable. "Changes this drastic could do irreparable harm."

Silence encroached in the room, the Commander still weighing. "Can you guarantee his cognitive functions will remain intact?"

"Well, maybe…"

"Then you are worried about his developing normally, after the spell?"

The man nodded, glad to hear reason from the man. "Yes, I fear he won't be able to mature into a healthy adult."

The Commander turned back to the boy laying helpless , his eyes intent on the scar emblazoned in the center of the teen's forehead. Silence again fell before he spoke, condemning both the teen and the man. "So long as he can function once you're done, his normal development is relevant."

The robed man slowly looked from the Commander to the two men behind him, then to Dr. Akagi and finally to herself. His face was incredulous as all he found within their features was cold indifference to the words their leader had uttered. "You're all crazy," he muttered, while his hands began to shake.

"Harsh times call for harsh measures." Was the Commander's terse reply.

"No. I refuse. I won't do it."

"Then your presence is no longer needed."

With a single motion the man pulled from his robe a long, thin piece of wood. At that motion the two men behind the Commander pulled their weapons. Rei tensed, preparing herself in case the man used his magic.

"I won't let you do this to him. No child deserves it."

The Commander remained calm and undaunted. "Then you have become a liability."

While desperation shown in the man's eyes, a practiced calm overcame his hands. With quick motions, he swished his wand and pointed it at the Commander. Rei was surprised no words were spoken, for she had been briefed they would be necessary. Nerv's knowledge of their capabilities were still somewhat limited. Despite that, she could feel something building within both the man and the wand, coalescing quickly in the tip.

Her eyes narrowed and she focused, calling forth the barrier to protect the Commander.

The man completed the quick motion and a blue light shot from the tip of the wand, only to be stopped by a transparent hexagonal field. The light skittered across the field before dissipating, the magic unrealized.

Contact with the magic gone, the field vanished.

Wide-eyed the man cast two spells in quick succession, both meeting the same fate as the field reappeared. The man darted a glance to Rei, noting her attention on him. He adjusted his aim.

"Fire." Twin gunshots erupted from two barrels, the bullets burying themselves in the wizard's face.

Silence fell like a curtain, the only sound was the rustling of cloth as the two men holstered their guns. Across the Commander the prone body lay limp on the floor, a large red smear decorated the wall behind it. The Commander turned away and wiped splattered blood from his face. "Call for a clean-up." One of the men brought a hand to his ear and spoke in low tones, while the other went to search the body. The Commander turned to Rei. "Good-job."

She gave him a small smile, words unnecessary, unneeded.

Dr. Akagi looked on disgusted. "Brutal as ever," she said, pointedly ignoring the mess.

The Commander tensed; Rei sensed the doctor was referring to something more than just the Commander's orders.

His eyes grew hard before speaking. "I am doing this to satisfy your scientific curiosity." She snorted. "Among other things," he amended.

She sighed and rubbed her temples, the gunshots were excessively loud in the enclosed space. "We're taking too many risks with their magic." Dr. Akagi spoke the word with derision.

"You aren't familiar with it."

"No I'm not. I know the why behind it, just not the how of it. I won't more time to study it before putting…"

His voice cut her off. "Do you require more specimens?"

She waved the offer away. "No, what I have will suffice. Everything is being rushed and there are too many unknowns, unlike with Eva." She sighed. "There's just not enough time."

Gendo stared at her for a long moment. "You don't understand Eva, either."

Puzzlement came over Dr. Akagi's face, but before she could respond, the clean-up crew had arrived. They quickly set to work, bagging the body and collecting the pieces of the dead man's brain. Gendo turned from her, speaking brusquely. "I'll speak with the committee about finding a suitable wizard for our needs."

With that he left, taking with him, like shadows, the two men in black suits and Rei.

Consciousness came slowly to Harry Potter, the bright light, at first dim to his sleepy mind, seared his eyes as they tried to adjust. The ceiling was unfamiliar, white and vacant. He tried to move his limbs, but found his hands bound with restraints; the same treatment had befallen his feet. He struggled against them, memories of floating in that horrible tube coming to mind. He feared what else the strange lady with the intense eyes would subject him to.

There was one relief for this new scenario, the world was no longer tinted orange.

"He's ready." Came a familiar feminine voice.

Harry looked to it and was able to finally see her face without interference. She had blond hair with the brown roots, a sharp chin and abrupt nose. Like a tear, just below her eye, was a mole. Harry would hazard to say she was pretty, had he not known what sort of mind lurked behind her eyes.

"Proceed." Came a deep voice from a man standing well back, flanked by two men in black suits and shades. Currently, their hands were resting inside their jackets, but their faces were not pointed towards himself. They were angled at the man standing at the base of the bed adorned in familiar and comforting attire. Robes!

"You've got to help me!" Harry cried, his struggles renewed against the bindings. He noted the man bring a twisted wand to bear. "They've done weird…" His voice trailed to silence when the harsh reality of the situation bore down upon him. "You're with them," he whispered harshly.

Two emerald green eyes flashed in anger, an emotion hiding the fear in his heart. The fear caused his hands to quiver. The strange man, with blunt features, long black hair, and sinister looking eyes, began to move the wand in an intricate pattern, while the tip began to glow. Harry looked away and found a small girl his age tucked away in corner. She had ruby eyes, pallid skin, and light blue hair. It was the strangest complexion he had ever seen.

The observation was pushed aside when he heard the wizard hovering over him complete the spell with an incantation. It was in a language he could not comprehend. He wondered briefly if the people in the room had been speaking English for his benefit. This observation, too, was brushed aside as the light from the wand fell over him.

A tickling sensation swept through his body, racing towards his mind. Nerves flared to life then deadened as the spell encroaching upon his being. Then he felt it strike his mind, invading with the precision of a sharp pick. His body writhed in agony as he tried in vain to fight off the effects; not even sure what the purpose of the spell was.

Then everything went calm as bliss supplanted pain, lull replaced discomfort. He was actually quite happy all of a sudden, floating in a place in his mind with nothing but the clouds to worry about. Below him he could feel things shifting, but it was a detached sensation. Nothing to worry about at all, but curiosity got the better of him and he peaked, even though the clouds urged him to just relax. What he saw brought back the panic and now rage at the violation.

There, spread out like a never-ending quilt, were his memories of Hogwarts and his friends. Thousands of moments, like moving pictures, captured forever and stored within his mind. And there, like a poison of white light, was the spell slowly slithering among them and severing them. Harry witnessed segments of good times and bad cut away from his consciousness, falling away to a black abyss leaving nothing but emptiness where there should be emotion.

Rage consumed him and he plummeted downward, shrugging off the clouds as they sought to contain him. He fell upon the white poison and struggled with it, flinging off its corrosive light trying to hold onto that which was precious. For long eternities they struggled, memories stirred and memories forgotten. Patches and holes appeared throughout the fabric as he fought, hot rage and cold fear driving him ever onward. He could not let this thing take away the only bright spot in his entire life, but it was hard and he was growing tired.

Soon his struggles died and he lay there among the best times of his life, while a foreign invader surgically cut-away what was him, and supplanted other memories that rang hollow and wrong to the teen. But they were now there, a new fabric to replace the old; a part of him, though he felt the wrongness of it to his very bones.

He cried out in frustration and did the only thing he could; hold onto what memories he could, shoving them beneath the new fabric, hoping and praying the poison would not get them. Hermione, Ron, Mrs. Weasley, her husband… He screamed into the void when he realized he could no longer recall his best friend's father. He grabbed more moments, some random, some recalled, and all desperately wanted. Ginny, the basilisk, Quidditch, his firebolt, Sirius, Dumbledore…

Then the fabric of his old life was no longer; all that remained was a new one. And Harry sat among the memories, knowing them for his own and wondering why he was crying and angry. He recalled the long years under his aunt and uncle's imperious stares. Their frequent name calling: freak, wretch, ingrate. How he wished his mother and father had not died in a car accident leaving him with them.

He remembered the boarding school they sent him to when he was eleven, how out-of-place he felt and how he made no friends. All he knew there were frowns upon stranger's faces. Then came the strange Japanese man with his tests. How Harry had worked the computer with ease, answering the questions as best he could. Doctors had come and taken blood and run weird lights over him. The experiments made him uncomfortable, but he bore it in silence, as he did most things in his life.

Then the phone call and the moment of pure elation. He was being shipped half-way around the world to work in a Japanese-funded program linked to helping mankind fight the strange beings known as Angels. The Japanese man said he could help in the war and save mankind. It was a noble cause, one Harry believed in completely, but what truly set his spirits high was leaving his relatives place forever.

I'm dreaming. He quickly realized, looking about the place strangely. The last he remembered before falling asleep was boarding a plane with his luggage. I must have dozed; it is a long flight…

The final thought fell away as he truly did fall asleep, lulled there by drugs placed into his system. Letting him escape the place where Harry Potter, Boy-who-lived, ceased to be; replaced by Harry Potter, Fourth Child.

a/n:: Hopefully, this will be a successful attempt to meld two very different worlds. I've actually tried looking for a decent HP:NGE x-over, but no luck. So like most, I wrote one. Inspiration was not mine alone I dare say, I grabbed the idea from a random forum thread. From there the idea peculated in my head for a time, and let me tell you, merging these two worlds was some of the hardest imagining I have ever done. Hope people enjoy the results of that labor.

-byl, out.
