I've decided to expand the fanfiction. I hope you like it.
I've only seen fanfictions where Harry becomes the Overlord. Now here's something completely different.
Disclaimer: I don't own Harry Potter or Overlord. If I had, Overlord would have had some really hot scenes with the mistresses, and HP would've been much darker and evil…
Voldemort fell backward, arms splayed, the slit pupils of the scarlet eyes rolling upward. Tom Riddle hit the floor with a mundane finality, his body feeble and shrunken, the white hands empty, the snakelike face vacant and unknowing. Voldemort was dead, killed by his own rebounding curse, and Harry stood with two wands in his hand, staring down at his enemy. Harry was relieved. He had defeated his enemy. The students cheered and raced to him. Ginny and Hermione got to him first and squeezed him between them. He enjoyed it.
Above him, in the shadows, a large spider hissed. Its rider, a green creature that could've been mistaken for a house – elf, calmed it. The time had come. It had a task. The creature tapped a jewel on a band around its wrist and grinned, showing sharp teeth. Task completed.
The entire castle shook.
"Earthquake!" Harry exclaimed.
"That's impossible! The castle is protected from earthquakes!" Hermione shouted as they ran towards the nearest table. They hid under it, along with several more students.
"The charms must've been weakened or destroyed in the battle." Harry guessed. But he was wrong.
A claw – like thing burst from the floor. Around it four holes appeared, each one glowing in different color – brown, red, green and blue. For about a minute nothing happened. Everyone emerged from their hiding places and approached the strange thing. It was like an irregular circle shaped platform with six curved spikes positioned around it. A blue light emanated from the center of the structure and it was surrounded by angular surfaces arranged like stairs. The light emerging from the four holes was too bright to see what was inside them.
"It looks like a…" Hermione started, but never finished the sentence. In that moment all hell broke loose.
An arrow came from the portal and hit professor McGonagall in the throat, killing her on the spot. The students screamed and more arrows came out of the portal, killing or wounding many of the people around it. Panic took over and almost everyone started running. Harry and the D.A. were the only ones that remained calm. They placed shielding spells around them and readied for everything. Or almost everything…
Something emerged from the portal. The panicked students and teachers stopped running and screaming. The silence was deafening. The creature was at least two, two and a half meters tall, about one and a half wide, all covered in muscles and armour. Its helmeted head turned around, examining the crowd. Two more gargantuan creatures emerged from the portal and drew their enormous swords. The crowd started panicking again. The creatures charged in three different directions, trampling the wizards and slicing around with their swords. Harry jumped from one's way, but Neville was too slow. The thing's sword slashed to the left and Neville's top half fell to the floor. Harry shot a stunner at the creature, but the spell had little to no effect.
"Split up! We'll meet at the Room of requirements!" Harry shouted to Hermione. She nodded and replied the order to the rest. Then she and Ginny darted through the crowd. As they neared two of the four holes a house – elf leaped from it and smacked Ginny on the back of her head. She fell unconscious and the thing turned its attention towards Hermione. She set it on fire and tried to wake Ginny up. Harry saw a large spider carrying a green house – elf leaping towards her. He shouted a warning but it was too late. The thing tackled her to the floor and enveloped her in a cocoon. Then the spider cocooned Ginny too. More house – elves poured from the holes, bringing wolves, giant salamanders and spiders. From the big portal came another wave of arrows which was followed by a seemingly endless stream of soldiers. A small part of Harry's brain noted that they were similar to the soldiers of the ancient Roman Empire, while the rest of his brain told him to run. He made his way through the crowd that had started to fire spells in almost every direction.
He reached the stairway and went up. Behind him the mass of wizards was screaming – both curses and from pain as they were being set on fire or wounded by arrows and swords…
The stream of soldiers ended and a tall humanoid figure emerged from the portal. It looked around and his yellow glowing eyes stopped at the cocoons placed next to the nearest wall. The figure lifter its hand and a couple of brown minions dragged one wriggling cocoon to him. They set it upwards and a red minion directed a salamander's fire towards the front of it. The web melted and a brown haired girl dropped from it. A pair of browns held her down while the Overlord stepped closer. She looked at him and spat. He smiled under his helmet. She would make a fine mistress. He held his left hand towards her head and charged his Evil presence spell. The room's lights seemed to dim as he released the spell. Blue lightning connected his hand with her head. Hermione screamed and arched her back from the pain. Her mind went dark…
Well, here's the first chapter. I hope you like it. Read and review, please.
