Death...the Master of Death...the Master Destroyer...the Fourth Horseman of the Apocalypse...the Destroyer of Worlds...the Destroyer of Souls...or just Harry James Potter sat silently in the middle of a small, black abyss, which appeared the size of a standard Azkaban cell. It was not a normal room though, for it had no door, no light, and no life. The only presence was Harry, and Harry alone could access the center of Death itself. A gateway to hell through the Zeroverse, meaning he could be anywhere at any time. Omnipresence. The omnipresent entity sat on a black throne made of black stone, leather, and elder wood, his attention on the mirror in front of him. He could not say he liked his appearance, but he did not hate it either. It was mysterious...horrifying...and worked well when it came to petrifying his victims and enemies. He was Death after all and needed any advantage he could get against mortals, gods, and other deities much like himself, who were bound to be spread across the Multiverse.

In his past life as the wizard Harry Potter, which had taken place roughly over 81 Eons before - Harry couldn't tell seeing as he had lost all meaning of time as he jumped through universes, planets, and time itself - he had united the Deathly Hallows at the age of nineteen, becoming a mass of bone, darkness, and death. He had then destroyed the dark arts and led a peaceful life among the light without war and conflict...for eight years until devastation took over the world, and everyone died. At that point, he stopped giving a shit and began to lead the revolution against civilization itself...three times. He had done it the first time, and destroyed practically everything, before rewinding time to do it all again, just for fun. The third time had been a mistake, seeing as he had accidentally forgotten to give the Peverell brothers their Deathly Hallows, and maybe-kind of-sorta destroyed the entire universe itself. This drove him into the Zeroverse, where he stayed when he wasn't traveling the Multiverse.

And after fifty billion years of existence - at least he thinks it had been that long - Harry had traveled the entire Multiverse, destroying universe after universe, one after the other. Well, he didn't destroy them because he wanted to...not all the time. Most of them were already dead, and he just finished the job to allow room for new lively universes, and others were ruled by mass dark empires that he was forced to annihilate. He had murdered trillions of civilizations in his lifetime and had killed so many mortals he had lost count not a year after becoming Death. With that Multiverse annihilated, he entered the greater Omniverse and began to go from Multiverse to Multiverse to occupy his time. And to be honest, Harry was bored. He had lived over trillions of lifetimes and had done everything imaginable. Drink a cup of lava? Check. Pass through a quasi-star? Check. Go back in time to live out a life in which his parents lived? Check. Eat a box of actual donkey shit? Check, and don't ask, he had been in a rough spot. He had done every possible thing imaginable, from the tiniest of things to the largest things in the Omniverse. Now...now he had nothing to do.

Sure, there were new universes he could explore and he could always make new memories in throughout the Multiverse, but that was all rather boring. He had been a Dark Lord more than once, he had killed Tom Riddle Jr fifteen million times out of pure joy and had murdered himself at least twice. All of that had waisted away his soul, making him a mere shell of his former self. He now had a skeletal appearance, his entire form looking as if he hadn't been fed in years...which he hadn't, seeing as he fed off of the souls of the living...which kind of sucked. His skin was still Caucasian, unlike the pure white of Tom Riddle in his later life. Harry's fingers were large and scaly, much like the hand of a dementor, which ironically he had created in almost every timeline or universe he had ever visited except for the now destroyed original timeline, where they were created by Ekrizdis, a man of the dark arts who fled to a mysterious island where he built what would be known as the prison of Azkaban. There, he spent years perfecting the dark arts, creating the dementors.

Harry didn't use a scythe like most interpretations of Death, seeing as he was a master in wandless magic as well as universal magic. He could create anything he wanted, but he couldn't manipulate space, matter, or even life. All he could do was kill, and create things from his home, the Zeroverse. He possessed many abilities besides the ability to create, including but not limited to; the ability to manipulate the elements, complete control over all magic, a very handy regenerative power that would bring him back from a sub-atom, as well as omnipresence, which gave him the ability to be anywhere and everywhere at once. Though one ability he didn't have...was focus. Harry was pulled from his long thoughts as he felt a small tug from his navel. Harry perked up at this, a smile on his face as he looked down. Death had felt tugs such as this one trillions of times before from mortals who either wished for death or wished for others' deaths, but...this one was different. He could feel something...new...behind it. If it wasn't something he had done before, then he was down to try it. After all...he was extremely bored.

Another tug pulled on his navel, slightly more powerful than the first, and he could make out a tiny white string moving out of his cloak. It traveled away, before disappearing into nothingness in front of him. Harry delicately grabbed the string with his thumb and forefinger, silently tugging it as it grew brighter and grew slightly. Another tug caught his attention, this one being much stronger, nearly pulling him off of the chair in a sense of urgency he had never seen. His smile increased ten-fold as he stood up from the chair, the string growing even brighter as it realized it had gained his recognition. Harry followed the string and realized that it disappeared two feet in front of the wall, into nothingness. He grinned down at the string and began to force his magic into it. His magic traveled through the string, forcing itself into the small rift in space and time, tearing it open to reveal...darkness. Nothing but darkness.

He poked his finger through the rift and was immediately hit with a mound of knowledge at his presence within the new universe. Harry could also tell that this universe contained…no entity known as Death, and could feel as subconsciously he began to pass souls from the mortal world to heaven and hell, as well as save dozens of souls. He hadn't done that in eons, seeing as his own universe in which he passed souls through had been destroyed by his own hand. This was the first universe he had ever come across without an entity known as Death and he was surprised. Harry had met millions of other Deaths, personified as either males or females. He got along great with the male Death's and would have quite a blast killing asshole Dark Lords and evil tyrants. And he had good times with the female Death's, having hundreds of sexual relationships with several of them that lasted ages each. After all, Death couldn't touch mortals without killing them, making relationships with them...hard. So meeting a Death of the opposite gender was always a plus.

Harry knew he needed to be cautious, but...damn his curiosity. Harry took a seat on his throne and tapped the right armrest four times in a specific pattern. At once, a metal vest suddenly shot around his torso, a small blue orb placed within the center. "Well, it looks like it's another trip via the Nexus then." The Nexus was a temporal device Harry had created that anchored his main body to the Zeroverse, while another him was shot through the Multiverse towards his intended destination. He had millions of different hims throughout the Multiverse, occupying thousands of different continuities. He tapped another few patterns before a blue light began to brighten from his chest, the light illuminating the usually dark room. There were six lights illuminating within the blue core. A darker blue, red, orange, yellow, green, and purple. With a single tap, a beam of rose-red shot out of the core, striking the rift as it burst with white light. After a moment, the Nexus disengaged back into the seat, and Harry leaned back with a sigh. He really needed to do something...fun.

Unknown Date - Multiverse - Sector 31.199999-A

As soon as Harry emerged from the Zeroverse, the first thing he did was shed his black cloak into nothingness before he was left in nothing, his body out for all to see. His ribs were out in the open, his pale skin appeared soft and near nonexistent as his skeletal figure apparent beneath his pale skin. His black eyes would darken even the brightest of souls, his black hair now reached down to his shoulders, and his height had increased to the point that he was 5' 11". With the wiggle of his finger, his appearance suddenly began to change. His appearance bulked, his body mass increasing in muscle as his body began to expand to what he looked like as a sixteen-year-old in his old life. Well...the first one anyway, not that it mattered much. His pale skin began to tan, his hands and limbs shrinking slightly so he wasn't so lanky in appearance. Once his legs, torso, arms, feet, and hands stopped changing, clothing began to appear around him.

Blue trousers appeared over his legs, accompanied by white socks and blue oxfords. His torso remained uncovered until a white buttoned-up shirt appeared around him. A blue, red, and white tie appeared around his neck before his shirt was covered by a blue waistcoat. That was then covered by a blue coat, completing his ensemble...partially. A wand holster appeared beneath his right sleeve. A golden chain looped itself around his neck under his shirt, a time-turner. A silver cloak wrapped around his neck, becoming invisible as he remained visible. The last additions were two rings. One being the Gaunt ring which held the Resurrection Stone, and the other being...well, it was a trade secret. A short beard appeared over his chin and upper lip, and his hair became much shorter and manageable. His eyes returned to their original shade of emerald green before they were covered by materialized circular-framed glasses. His hands were covered by blue gloves, keeping anyone or anything from obtaining his DNA, even though he doubted anyone could do anything with such a thing. After all, from where he stood it appeared to be sometime in 1941.

His legs carried him out of the alley he was currently in, taking him onto the busy street accompanied by primitive cars, pedestrians, and cyclists. Harry's eyes caught the local paper stand, and he quickly moved across traffic, avoiding the honking cars and yelling citizens as he reached into his pocket. He retrieved a dime from his pocket, which was conveniently connected to the Zeroverse, and placed it within the newspaper box. Harry retrieved a newspaper from the box and began to read. The date was April 21st, 1941. And the biggest thing in the news at the moment had occurred eight days before when the Soviet-Japanese Neutrality Pact, which would last for five years. April 21st...1941. Why was he here? Well, he knew how he'd gotten here, and the fact he had been called to this universe for assistance, but...why? To assist in WWII? To help Dumbledore in the fight against Grindelwald?

Grindelwald. Harry hated the man almost as much as he hated Voldemort, and that was saying something seeing as the latter had not only killed his mother and father but his friends as well. He was in the world he'd never seen before. One that had called to him, something that had never done that before in his extremely long life. Ever. Usually, he would go to a new universe or an existing one, give himself new memories, live a life, 'die', regain his memories, go back to the Zeroverse, and repeat the process. Now though, he was actually somewhere with all of his memories, and even more important...he was needed. He hadn't been needed since his first life, and that was merely because he had accidentally killed a sixty-year-old man with...love. The only thing that bothered him was his powers. He had only a minimal amount of them, given how the Harry Potter in the Zeroverse was the real Death of this new universe, which meant he was...just Harry. A vessel of his former self.

His memories hazing over each other, Harry shook his head to clear his thoughts and moved away from the paper box. He needed to get everything he could on this universe. Every piece of history, every artifact, its important places, people, events, everything. That's why he went to the one place he knew he could find...well, most of that information. The Library of Congress in Washington D.C...202 miles away from where he currently stood in Brooklyn. Harry sat within the library for three days under an extremely strong Notice-Me-Not charm. He had written down an entire timeline for this universe, starting from the big bang to the present day. The timeline was a rough draft, obviously, but with the help of the library's restricted section, he could fill in a lot of the blanks. The Harry Potter of this universe - who he had kicked out of his body upon Harry's arrival - had been born on July 31st, 1924, making him sixteen in this universe. He had graduated from Phillips Academy in Andover, Massachusetts at the age of twelve, before graduating MIT with seven majors and ten minors at the age of fifteen. After a year of research and building connections, Harry Potter started his own company he named Potter Incorporated or Potter Inc.

The company itself was fixated on medicine, technology, and bioengineering. Harry personally liked all three fields, working with potions, merging magic and technology, and creating different test strands of nanotechnology. The other Harry had gotten nowhere with the nanotechnology through normal means, so now Harry would be forced to kick start it with help from the Zeroverse. So far, the old Harry Potter refused to provide anything to the Allies but medical supplies, potions disguised as medicine, and small prank items in the form of tiny pebbles placed in large containers. It seemed his new company would even send them out in weekly shipments. Out of the entire list of potions available in 1941, the other Harry had introduced over a dozen to the new muggle world. The Anti-Paralysis Potion, the Blemish Blitzer, the Blood Replenishing Potion, the Burn-Healing Paste, the Calming Draught, the Cough Potion, the Draught of Living Death, the Draught of Peace, the Dreamless Sleep Potion, the Grand Pepperup Potion, the Sleekeazy's Hair Potion, the Sleeping Draught, the Skele-Gro Potion, the Wiggenweld Potion, and the Wound-Cleaning Potion, all in the form of muggle medicine.

After the Soviet's invasion of Poland from the east, the other Harry had apparently begun the planning and production of a new weapon. Something that would help him crush anyone who faced him in a fight. At this point he had been prepared for anything...except for cosmic entities or aliens...yet. Harry then looked up his name in the records and found almost eleven dozen pages of information on him in a single book, including four properties around the world, five companies under Potter Inc, dozens of office buildings, dozens of warehouses, off-grid safehouses, over 96 billion dollars in an offshore account in the Cayman Islands, and over 9 billion dollars within the Potter Inc Gold Reserves.

Harry didn't really need the money, seeing as he could create anything he needed or wanted in the matter of milliseconds without breaking a sweat. He didn't even know why he would start a company like this, seeing as he didn't care much for people nowadays. They took things for granted. They praised him when he gifted them with life, but cursed him when their time was just a bit terrible. It was like his time as the Boy-Who-Lived. The wizarding world prayed to and for him as a boy for his mother's sacrifice, and when he informed them of the return of Voldemort, they shunned him and made him a desirable for the Ministry. People were really stupid, something he had come to realize a long time before. Collecting his things from the library, Harry took a deep breath and disappeared. He had things to do.

The first ten chapters of this story were rewritten due to plot issues and lack of information on my part. This message is just to let you know that in the future, this story will be updated and changed depending on new developments or if I just feel like adding or taking out something I feel should/shouldn't be there.
