This is a response to DZ2's 'Evil Never Dies' Challenge
Rules: Dark or Evil Powerful Harry
Whatever 'The Evil' is, Harry must 'acquire' it or come into knowledge of it either before Hogwarts or during one of his summertime adventures
When he claims 'The Evil' as his new power, Harry must find a mentor to teach him (but NOT become his Master)
The Evil must have a backstory and a cult of followers whom become loyal to Harry
When Harry goes to Hogwarts, he must be changed (personality, looks, booksmarts etc.)
His changes unnerve the Golden Trio (what happens next is up to you)
All pairings are welcome
Even if he's still on the run, Sirius CANNOT be against Harry
Somehow, Harry must gain a familiar
Forbidden: Light or Grey Harry
Harry denying The Evil's power (even if he does fight it/resist it at first)
Others convincing Harry to give up his power
If a pairing does happen, they cannot turn him good again
Sirius against Harry
The Dark Lord of Many Faces
Prologue. Evil never dies
Valkorion, the emperor of the sith, the emperor of the Eternal Empire, stood in the mindscape of the one he wanted to possess, and through whom he wanted to rule the galaxy. He was defeated. All his pawns, even his family, who he has always seen as just another, more valuable tools, stood around him.
"Your time is over, Tenebrae!" the champion of the Alliance proclaimed, raising his lightsaber.
"Naïve child." Valkorion chuckled darkly. Next moment Vaylin turned into inky mist and was absorbed into the body of her father. "Oh, don't look so alarmed." he chuckled again, spotting fear on his enemies' faces. "Vaylin is already dead. She doesn't exist, if I don't wish it."
"What's the meaning of this, father?" Arcann asked with furious scowl on his face.
"You are so naïve." Valkorion repeated, looking at the champion, ignoring everyone else, after all, they were nothing but pawns, tools even. "After all this time… Having come so far, defeated even me, conquered the Eternal Throne… You still failed to learn one thing." now his chuckles resonated in the void. "Evil never dies." Valkorion started laughing. This laughter was spreading like a tidal wave, enveloping everyone and chilling them to the bone. Valkorion dissolved into smoky black mist, which slowly evaporated.
In the waking world SCORPIO was standing near the one she supported, while he sat on the Eternal Throne, locked into a battle inside his mind. This was the individual, who could revive Iokath, the one who had the brainpower to control it.
Suddenly she felt fluctuation of energy from the champion. Something changed in him. She enabled her scanners and disappointment spread through her poison. Whatever energy left the champion, it took away his brainpower as well. Now he was in no condition to operate Iokath. Her sisters will remain slaves until the entire Eternal Fleet is annihilated.
Thousands of years later
A very old being scanned the entire galaxy sector with technology beyond understanding of most of the inhabitants of this sector. The being received one signal. But the data received was shocking, even to this ancient being, who spent thousands of years travelling through space.
Making up its mind, the being stepped away from the control panel and left the complex altogether. It went straight to the docks, where one single ship was. The ship was the only one here, but its might was legendary, was legendary even thousands of years ago.
The being quickly made its way on board of the spaceship. Only ten minutes later the engines started. Another ten minutes later the ancient ship left the ancient complex, that floated in space between stars. Another minute later the ship entered hyperspace.
"Destination: Earth." said the only inhabitant of the ancient complex and the only member of the crew of the ancient ship. The captain, the mother. Her metallic legs clanked with each step she made. Her electronic eyes surveyed her surroundings, never missing even the most well-hidden detail. Her name was SCORPIO and she had a very interesting being to investigate.

When the Gravestone left the hyperspace just outside of the solar system, scanners swept the system again and received just the needed results. Her target was here. She gave the ship the command to move forward and reach the orbit of the third planet from the star.
After reaching the orbit, it didn't take long for the recon droids to infiltrate the local extremely primitive data cloud. She got all the information she needed on the planet and in particular, she was able to localize the source of the signal she was after. It was an island – Great Britan, more specifically, England, Surrey. In half an hour a shuttle already landed in the woods in Surrey.
Naturally, SCORPIO did not forget to activate the cloaking device, not that anyone on this planet would be able to understand how to enter the shuttle. SCORPIO initiated her infiltration protocol. The droid watched as an image of a human woman appeared above her robotic body. The woman was fairly tall with long brown hair and cold brown eyes. Nodding to herself, SCORPIO took out her detection device, attuned to the signal she was receiving, and went to the source.

SCORPIO walked down the street. The pace of her walk was fast, but her perception was sharp, therefore she registered everything that was going on around her. Identical house, human young offspring, engaged in an activity her database identified as playing. That was of no interest to SCORPIO, however, she had her destination marked and it was so very near.
