So yeah the first real chapter, not too much happens in this but I figured this is what my Harry would do first thing he could.
…
It was the night before Vernon's big deal and all through the house not a creature was stirring, not even a mouse. Vernon was upstairs snoring, Petunia was in the same bed her earplugs firmly in place. Dudley was in his room dreaming of cake, Hedwig was outside hunting and Harry James Potter was nowhere to be seen. Harry was in fact near the middle of London.
Staggering off of the knight bus and cursing whoever came up with such an invention Harry made his way through the leaky cauldron and into Diagon Alley. Normally Harry would have detoured to Knocturn and attempted to strike several contracts with it's inhabitants but at the moment he was weak and decided that it would not be safe just yet. Instead of heading to Knockturn Harry instead made his way to Gringott's, which was open twenty four hours a day.
As Harry stepped into Gringott's he remembered the goblins, how they were originally created by Baal as her thieving little servants, Harry found it a bit funny that they found a legal way to steal people's gold for their mistress.
"I need to withdraw money to the equivalent of five hundred Muggle pounds," Harry told the first teller that he came across.
The Teller just sneered at Harry before it pulled a newspaper out of nowhere and began to read, "I'm on a break," was all it said.
Now if it was the old Harry who didn't remember that he was a raised demon then he would have just apologised and went to go find another goblin to talk to, that Harry was still in there but now there was also a Harry who was used to lesser beings doing as he told so he decided to teach the goblin it's place.
"I am a high ranking vassal of Mephistopheles' court and last I checked your mistress owed him quite a lot, I wonder how she will react when Mephistopheles cashes in all of his debts because of one, tiny, insignificant, lazy little goblin," he challenged as imperiously as possible.
The goblin raised an eye at that but continued to read it's newspaper, "you should try to tell more believable lies," it commented.
Harry smirked as an idea came to him, "care to make a small wager on that then?" he asked, gaining the goblin's attention if only barely.
"And what would you care to bet human?" the goblin asked idly.
"All of the gold in my vault against your soul," was Harry's blithe response.
This did grab the goblin's attention, and that of all the goblins in the bank atrium, "did you say my soul?" the goblin asked, paling slightly.
Harry clicked his fingers and a Devil's Contract written on goblin-skin parchment appeared on the teller's desk. "the contract states that if in the space of a week I can gather reasonable evidence to prove myself as a vassal of the great Demon Lord Mephistopheles then I acquire ownership of your soul, if not then you acquire every single Knut, Sickle and Galleon in my vault. All it requires is your signature goblin," Harry finished with a leer.
The goblin gulped nervously as it looked at the contract in front of it, shakily it reached for it's quill, "how did you want those five hundred pounds sir?" it asked grabbing a withdrawal slip as it did it's best to ignore the contract in front of it.
"Not going to take me up on my bet goblin?" Harry asked with a cruel smirk, "I thought that everything I said was just unbelievable lies, it should be easy money for you right?"
the goblin for his part didn't say anything and just slowly counted out Harry's money before handing it to him with a shaky hand.
Harry grabbed the money and pocketed it, "by the way I'm not a vassal of Mephistopheles, I am his adopted son," Harry said, "you really should have taken that bet," with that he left the bank, laughing at the look on the goblin's face as he did so.
…
instead of going to a hotel or somewhere nicer Harry made his way back to Privet Drive and waited for the day to start so that he could have some fun. As soon as the sun began to rise Harry was once more out of the house and at the local park, watching and waiting for his first victim to show up.
Gordon Daniels was a member of Dudley's gang and like all of his friends was a stupid, selfish brute with an IQ lower than that of a troll, this was perfect for what Harry had planned.
"Hey Gordon got a minute?" Harry called out to the bully.
Gordon gave a pathetic attempt at a sneer when he heard Harry call out to him, "looking to play a game of Harry Hunting, Potter?" he asked.
Harry ignored Gordon and gave his best attempt an an angelic smile, "actually Gordon I just came into some inheritance and was thinking that I would share the wealth around. How does that sound to you?" he asked.
Normally when someone who you bullied offered you money of his own free will you would be suspicious but Gordon really wasn't that bright. "Well hand it over then!" he demanded holding his hand out.
Harry internally cackled, he had Gordon right where he wanted him. "Well you see Gordon you see there is a few legal issues I just need you to sign something for me and the money will be yours," with a click of his fingerers Harry created a contract behind his back and held it and a pen out to Gordon, "just sign on the dotted line and you will receive a hundred pounds," Harry informed the slow witted boy.
Gordon signed the contract without even looking at it, "well where's my money Potter?" he asked with an impatient growl.
Harry sighed slightly, it really was no fun when they were so easy. Reaching into his pocket Harry pulled out a wad of bills, it was actually more than a hundred pounds not that it really mattered. The second Gordon snatched the money out of Harry's hand the Devil's Contract flared slightly before dissolving into smoke and Gordon collapsed in a limp heap on the ground.
Harry felt the slightly addictive feeling as Gordon's soul was absorbed into his, giving Harry a small increase in power. "Aaahhh that's the stuff," Harry sighed, a look of bliss on his face. "I can't believe I had forgotten what this felt like."
It was a few minutes later before Harry gathered himself enough to pay attention to his surroundings again, luckily there was no one else nearby who had seen Gordon collapse
"What's that Gordon?" harry asked, looking down at the soulless body of the bully, "you want to give all of this money to me? Are you sure?" he asked faux seriously. "I wouldn't want to take advantage of you...well if you insist." bending down harry snatched all of the money out of Gordon's hand before walking back to Number 4 while whistling cheerfully the entire way, "you know he was such a nice person that Gordon."
When the news that Gordon had fallen into a coma reached the Dursley household Harry had barely been able to contain his laughter but it was even better when the news that Dennis, Malcolm and Piers had also fallen into coma's later on in the week. The best though was when Harry had Dudley sign the contract though Harry didn't absorb Dudley's soul straight away, he had other ideas for his obese cousin.
Sitting comfortably on the Dursley's couch with his feet resting on his cousin's empty body Harry waited for Vernon and Petunia to come down stairs for dinner.
Petunia came into view first, she paled instantly at the scene in front of her, she knew instinctively, just as every mother knew, that her son was in danger. "Dudders!" she cried out. "Dudders get up! What did the freak do to you Dudders?" she cried rushing to her sons side, not even bothering to spare Harry a glance.
"That's it freak into the cupboard with you!" Vernon shouted.
"Poor Dudley never to walk, talk or even think again because his parents didn't want to listen to the freak," Harry sighed theatrically, "oh well I guess it's to the cupboard with me then."
"WHAT DID YOU DO TO MY PRECIOUS DUDDERS!" Petunia shrieked just as Vernon shouted, "WHAT DID YOU DO TO MY SON BOY!"
Harry adopted a look of pure innocence, "all I did was make a contract with him. Nothing important just one that stated for a few hundred pounds the Dudley would give me his eternal soul. As you can tell this is entirely his fault for agreeing to my contract, I never forced him to sign it after all."
"YOU FIX MY SON RIGHT NOW BOY!" Vernon shouted, turning a very purple colour.
"Are you sure you want that?" harry asked, "I mean he's so quite and polite now, and he won't ever whine about how he wants the latest toy or wants cake for breakfast lunch and dinner. I quite like him like this," Harry finished with a small smile.
"FIX HIM RIGHT THIS SECOND FREAK!" Vernon screamed, grabbing harry roughly by the throat and pulling his arm back.
"Punch me and you will never have you son back," Harry stated coldly. "He will just be a useless vegetable just like Gordon, Dennis, Malcolm and Piers. Forever!"
Vernon's fist froze, the large man unsure of what to do.
"What do you want?" Petunia asked weakly.
Harry adopted his cold, cruel smirk and clicked his fingers, two contracts appeared one in Petunia's hands the other in Vernon's. "Sign these," Harry ordered. Without any hesitation Petunia signed her contract before it flared slightly before dissolving in smoke. Vernon hesitated for a few seconds before he too signed his contract.
"Well I must say I thought that you two would try to bargain for something like your son's soul but no you two just signed your souls over to me for nothing. Pleasure doing business with you," Harry told them before watching in amusement as they collapsed into a heap on the ground. Harry waved his hand and three glowing balls of light appeared, floating in front of him. The glowing balls were his relatives souls.
"I am going to have a lot of fun with you three," harry murmured to the three souls. With barely a thought their entire existence was one of pain and torture. "I guess I should send that letter as well."
pulling a pen and paper out of his pocket Harry wrote a quick letter before running upstairs and getting Hedwig to deliver it for him.
The letter read as follows.
Dear Albus
You know I'm not too fond of what you did to me, wiping my mind? That's just not very nice of you is it?
Well just in case you were planning to rush over here and obliviate my mind once more I would like you to know that I am currently in the possession of the Dursleys' souls and they will never be placed back in their bodies if you do so.
I am eagerly awaiting your visit.
Yours, Harry James Potter, The-Demon-You-Pissed-Off.
Harry sat down once more on the couch and rested his feet on his cousins bulky frame, "you know he really should have thought it through a bit more before he decided to wipe my memories. Poor Albus he's not going to live for very long if he tries it again."
