Harry Potter and the Sons of JENOVA

Chapter I

"Warrior and Wizard"

Nibelheim was an ordinary small town, shadowed by the towering peaks of the Nibel Mountains. At the end of the town stood a rickety abandoned mansion. It was once the mayor's residence, but had fallen into disrepair in recent years. Deep within the bowls of the mansion, a young man tore through room after room, searching for something unknown.

He was a tall man, well over six feet tall, and his waist long white hair shown brightly in the moonlight. Dressed in a black leather battle suit, he continued to ransack the mansion, pausing only to read any reports or documents he uncovered. His glowing green eyes flared with anger as he began to pound on the walls, punching through the plaster and support beams. Those same eyes shone with a determination that only madness can inspire. This newly found madness and resolve drove him onward. He hadn't eaten or slept for days, not since he had since the horrors of his recent trip to Nibelhiem's Mako reactor. The monstrosities in the dark bowels of the reactor were too familiar to him. Each terror raised more and more questions about his unfamiliar past. And in this abandoned mansion were the answers he sought.

He kept striking the walls until he punched straight through a wall, leaving a massive chasm in his wake. Ripping the reminder of the wall to shreds, he found a staircase spiraling downwards. Conjuring a bit of magic a small puff of flame sparked to life on a discarded torch. Torch in hand, he walked down the steep stone stairs. The stairs began to wind downwards, spiraling into an unknown abyss. The man continued downwards without fear or hesitation. The stairs seemed to continue forever, burrowing deeper and deeper into the cold earth. Finally reaching the bottom, the man stepped into a dark, dank tunnel. The tunnel was old, far older than he was and looked like an ancient tomb or crypt. Skeletons littered the ground, red-eyed bats hung from the rafters, and an eerie yellow light beckoned from the end of the tunnel. The man immediately headed out towards the light, wallowing through the crumbling bones and dusty cobwebs. As he reached the door, the man heard the heavy drone of machinery and the fierce cackle of electricity.

'There's someone else here' he thought as he grasped the doorknob. He rushed into the room, instantly taken back at the sight. The vast room was a mad scientist's laboratory, just like in the movies he once saw in Midgar. From floor to ceiling, the walls were covered with massive shelves filled with books on chemistry, physics, biology, genetics, and subjects he couldn't even recognize. Test tubes filled with foaming liquids stood in uncountable racks while potions brewed in self-stirring pots. Bolts of electricity spat across the ceiling, illuminating a cloaked figure hunched over an experiment. Upon hearing the door open the figure spun round to face the intruder.

"Who are you?" came a cold reptilian hiss from under the cloak. "Who dares disturb Lord Voldemort?" came the hiss seeped in anger.

"My name is Sephiroth," replied the tall man in black. "And you are trespassing on Shin-Ra property. Leave. Now." Sephiroth stepped into the room, drawing his massive sword, the Masamune.

This cloaked man, this Lord Voldemort, began to laugh. It was an icy sound, one that would have sent chills up a normal man's spine. But Sephiroth was far from a normal man. He held his ground his sword ready to attack.

Voldemort continued to laugh, careless of the drawn blade. "You little fool. You can not harm Lord Voldemort with such puny mortal toys." Voldemort turned to face his opponent for the first time. In the low light Sephiroth could barely make out Voldemort's features. The face was a deathly alabaster, whiter than the whitest marble. His face was reptilian: flat and triangular. His nostrils were small slits and his tongue was forked like a serpents. The eyes were the most horrifying aspect of the dark one's visage. The orbs were a deep bloody red, the black pupils slits like a cat's eye. To look into Lord Voldemort's eyes was to look into the eyes of the devil himself.

Sephiroth refused to be intimidated by this demon serpent. His green eyes burned with fury as he launched his attack. "Be gone Snake!" he roared as he leapt into the air. Flipping in midair, Sephiroth drove his sword downwards; ready to cleave the Dark Lord in two. The sword flashed in the eerie light as it crashed through the lab table where Voldemort had been working. The table was reduced to splinters and dust, but there was no sign of Sephiroth's target. Sephiroth was momentarily confused until he heard a serpent's hiss behind him.

"Come now, warrior. You'll have to do better than that to defeat Lord Voldemort." Voldemort reached into the folds of his robes and pulled out a thin wand. He bowed to Sephiroth and assumed an en guard position. Smiling, he waved in Sephiroth, daring him to attack. Sephiroth was more than happy to oblige.

Again he rushed at Voldemort, sword aimed straight at Voldemort's chest. Voldemort stood calmly, never flinching or changing his position. At the last second, he disappeared right before Sephiroth's eyes; the sword stabbing right where Voldemort's black heart had been. Sephiroth's fury knew no bounds. Never before had ever been embarrassed by any foe. And the icy laughter from Voldemort only stroked the fires of his hatred. He rushed at Voldemort again and again, each time Voldemort disappearing at the last moment and reappearing elsewhere in the room, laughing at Sephiroth's inability to strike. This continued for the better part of an hour and destroyed most of the room.

"I grow tired of this game," yawned Voldemort as he sat down on a lab table. "It is time to end it." He raised his wand and pointed the tip at Sephiroth's chest. "CRUCIO!" he bellowed as a red bolt of lightning flew from the wand. The bolt struck Sephiroth in the chest, the immense pain coming instantly. Every cell in Sephiroth's body felt like it suddenly caught fire and was burning from the inside out. Blood poured from the pores of the exposed flesh. The incalculable pain brought Sephiroth to his knees. However, he did not cry out, not even when Voldemort poured more energy into the attack. Sephiroth leaved heavily on his sword refusing to cry out or fall over. Again and again Voldemort struck Sephiroth, determined to break the stubborn warrior. Sephiroth's determination began to overtake the waves of pain, resisting the curses.

"No! How can you possibly fight the Cruciatus Curse? It's not possible!" roared Voldemort.

Smiling weakly, Sephiroth slowly regained his vertical base. His eyes burning with defiance, he stared into Voldemort's heart. "I-am-accustomed-to-pain…" he growled. Overcoming the pain through sheer will alone, Sephiroth raised his fallen sword. A loud inhuman roar leapt from his throat as red, fiery waves erupted from his worn, bleeding body. He slowly levitated off the ground, as the red waves grew larger and brighter. Sephiroth looked down at the shocked Voldemort. Voldemort fired more curses at Sephiroth's floating form, but the bolts of magic bounced off the powered up warrior. The red waves of energy slowly faded to a bright white glow. Drawing his sword in front of him like a spear, Sephiroth roared as the white light grew brighter. Sephiroth looked down at the shocked Voldemort and plummeted sword first at the wizard.

"FALLEN ANGEL!" he roared as he hurtled towards Voldemort, a living bullet encased in white light.

"PROTEGO!" shouted Voldemort in response. Immediately, a silvery light surrounded Voldemort, shielding him from Sephiroth's attack. Sephiroth slammed into the barrier with the force of a runaway train. Lightning danced across the room as the two powers collided against one another. The shield had withstood the onslaught of the attack, but was beginning to give way under Sephiroth's vast power. The shield shattered in a magnificent explosion and both combatants were flung across the room from the blast. Sephiroth was catapulted backwards across the room, through several lab tables before colliding into a large bookcase. The case then fell on top of the warrior. Likewise, Voldemort was tossed backwards by the blast. He flew directly into the stonewall of the room, collapsing in a heap of black cloak. Neither fighter moved for several minutes, the explosion taking its toll on the already tired fighters. Sephiroth was the first to stir. His limit technique had taken a lot out of him and his body was still feeling the effects of Voldemort's Cruciatus Curses. He slowly rose out from under the bookcase, scattering books and papers across the room in the process. He slowly got back to his feet and, dragging his massive sword behind him, limped towards the now stirring Voldemort. Sephiroth stood above the semi-conscious Voldemort, preparing to strike him down once and for all. As he raised his sword for the final blow, Voldemort's crimson eyes snapped open.

"Imperio," he hissed as he pointed his wand at Sephiroth.

Immediately, Sephiroth stopped dead in his tracks. Voldemort stood up, focusing his power into Sephiroth's mind. Sephiroth's sword dropped from his hand, clattering on the floor. A small, barely recognizable smile crept across the stoic warrior's face. This was perhaps the most wonderful feeling he had ever experienced. Sephiroth felt a calm, peaceful, floating sensation sweep over him like a smooth breeze. All his pain, anger, and sadness were washed away, leaving only a feeling of uncanny bliss. The room slowly faded into nothingness, leaving only a relaxing calm.

Then he heard the voice. It was quiet serene voice that echoed within his ears. Listen, it said. Listen and bow to your new master…

Sephiroth began to obediently bow before Voldemort. Slowly and deliberately lowering himself to one knee.

Bow to me…Sephiroth was almost on the ground when a second voice penetrated his thoughts.

No. I bow to no man. I am my own master… came Sephiroth's own voice in the back of his mind.

"Never!" came a defiant snarl from Sephiroth's lips. "I will never bow to the likes of you!" Sephiroth tried to stand but couldn't find the strength. Fighting off the curse had stolen away most of his remaining energy. Realizing his spell was lacking the potency to ensnare Sephiroth, Voldemort cast the spell again. This time it was powerful enough to break Sephiroth's resolve. The proud warrior succumbed to the Imperius Curse. Now fully in control, Voldemort wormed his way into Sephiroth's subconscious. Instantly, flashes of memories, secrets, and the truth of Sephiroth's origins rushed into Voldemort's mind. He learned everything there was to know about Sephiroth's creation, JENOVA, Shin-ra, METEOR, and WEAPON. Taken back by this sudden overwhelming knowledge, Voldemort quickly came up with a devious and evil plan to use this world and warrior to his advantage. He manipulated Sephiroth's mind, twisting it to suit his sadistic purposes. He created false memories and feelings, convincing Sephiroth that he, Lord Voldemort, was his master. Stepping back to admire his handiwork, a smile spread across his serpentine features. This is going to be fun, he thought maniacally.

"Arise, Sephiroth," he commanded. "There is much work to be done, my friend."

-VII-

5 years later…

Sephiroth allowed himself a small smile. He had followed his master's instructions perfectly. He had awakened his mother JENOVA and unleashed the WEAPONS upon the world. Using the Black Materia, he summoned METEOR to destroy the planet herself. There was only one thing, one man left standing in his way...

Cloud Strife…
