A/N: I do not own either Harry Potter or Avengers. No money is being made from this.

Also, this story is somewhat similar to to Deux Ex Machine by Plot Bunny Whisperer, though it is drastically different from hers in execution. Hope you all enjoy it.

He wanted to massage his forehead, he really did. The headache that had been pounding against his skull was bad enough, but now he had to negotiate with the Midgardians about his brother's punishment, which was turning into more and more of an annoyance with every passing second.

He didn't understand, he really didn't, just why Nick son of Fury, was so adamant that his brother be punished on Midgard rather than on his home planet, on Asgard. Loki was, after all, a citizen of Asgard, not of Midgard.

He let a long sigh escape him when the dark skinned Midgardian began repeating his previous arguments. Yes, he knew his brother had done bad things. Yes, it was due to his brother that many had died an early death. Yes, his brother was the reason that property worth millions had been destroyed. And yes, he agreed that his brother should be punished.

But his brother should be punished on Asgard, as was proper and as All-Father had commanded. Even though it might not be through blood but Loki was All-Father's son, just like him. And it did not matter what his birth was, All-Father had taken him in and had raised him as his own and he himself had always regarded Loki as his brother.

He agreed that Loki was being a bit difficult now, but he was sure after this rebellious phrase will pass and Loki will come back to them. Loki was, after all, family. And family always sticks together, through thick and through thin.

With that in mind, Thor Son of Odin, began negotiating again –though it was more like haggling- with Nick son of Fury, about the fate of his brother.

It was subtle, very very subtle, the way it began. He didn't even see it until it was late, way too late; even though he –and every Asgardian worth their salt- knew just what it was. But as stated earlier, it was way too subtle for the Asgardian to recognize it.

It had, after all, begun very slowly, building up from the very scratch, creeping up on the unsuspecting populace of the massive flying ship, the group that was known as Avengers.

As such, it was not until the Man of Iron taunted Son of Fury about it that he noticed it. And he was ashamed to admit that he would not have noticed it even then, had it not been for the exact wording the man's statement. "What's with the all the chill Director?" The man of Iron asked with his eyebrows raised, "Trying to intimidate Thor with all this gloom and doom?" The man had said with lips quirked in a smirk.

Son of Fury had scowled at the Man of Iron for a moment, before he frowned rather heavily. "What had happened to the temperature control here?" The dark skinned Midgardian had asked as he had pressed his hands against his ear; 'microphone', Thor remembered.

The human on the other side must have said something as the son of Fury retorted, "It's not fine here Agent!" Son of Fury had snapped in the device and the Midgardian on the other side said something to which Son of Fury replied rather angrily, "Then your control system is not working properly. I see my own breath out here."

And now that the Son of Fury mentioned it, he could indeed see his own breath. But Thor was sure, that that hadn't been the case just a moment ago. And if it was cold enough that they could see their own breaths, then why was his metal chair not cold or the metal desk on which he was resting his hands not cold to touch.

Frowning, Thor looked around and found that everyone was in the similar condition. They were all frowning at the cold and were letting out a stream of white fog with every breath.

Thor's frown deepened and he again looked around the room, searching for the reason of the Man of Iron's comment about the gloom and doom. And indeed the man of iron had not been wrong. The shadows in the room seemed longer somehow, darker somehow. The colors too seemed dulled, as if they had rejected the light and the light itself seemed fade away, as if shying away from something.

Both of Thor's eyebrows got lost in his hairline as he remembered that the current situation, resembled a situation, a situation that was from a tale that he had heard when he had come across a statue of a screaming man in Asgard. It was a tale that every Asgardian was told, in hopes that they would never commit the same mistake that the screaming man had made.

The mistake, that they should never ever cross that being. Because nothing was so monstrous, so horrendous as the being described in those tales. It was a tale of a being so merciless and so unforgiving, that none of Asgardians wished to cross him, even by mistake.

In the entire history of Asgard, only one Asgardian had dared to cross that being and his fate had been so horrifying, so heart wrenching, that the All-Father had commissioned that statue –the statue of the screaming man- to serve as reminder to him and to the future generations. So as to see it and remember, remember to never cross that being.

The air in the room thickened as fog began to materialize, sticking to the floor but still slowly rising. The fog swirled and moved and swirled again and Thor's blood ran cold. The being was here.

Nick, Son of Fury, seemed to have noticed his reaction and the dark skinned man barked at him, "What is happening Thor!?" The man had thundered, "What do you know?" The man growled behind clenched teeth.

Knowing that panicking would do him no good, Thor closed his eyes as he took in a deep breath and slowly let it out. He opened his eyes and saw that every eye in the room was focused on him, watching him, observing him. "Someone's coming..." Thor announced unceremoniously, after all, how else he could announce the arrival of that being. "...And you all behave." He said eyeing the Man of iron for a moment. "This being is not to be trifled with."

"I will fucking behave as I like on my damn ship!" The one eyed man growled coldly and snapped, "Who's coming uninvited to my ship?"

"You will behave Midgardian." Thor, who was generally calm, snapped at the stubborn master spy. "This being can… no, not can, this being will kill you with a single thought."

Nick, son of Fury, was silenced in astonishment as the calm Asgardian snapped at him, but recovered within a moment and growled, "Who is this being?"

Whatever the god of thunder was about to say was cut off as a sound of a pair of footsteps and the sound of a cane stepping on the floor was heard from amongst the swirling fog. Thor stood up abruptly, his body tense. "No matter what...," He warned his companions "Do. not. attack. him."

But his warning seemed to have fallen on deaf ears, as every shield member trained their guns on the approaching figure, ready to shoot at a moment's notice.

As the fog seemed to part, a figure seemed to materialize through it. The being that had appeared, looked like any other human or Asgardian for that matter. His hair was dark, black as sky and seemed untamable and wild, as wild and untamable as typhoons, tornados and tsunamis combined.

But as wild as his hair was, it was nothing compared to his eyes. The dark green orbs were cold as ice or perhaps colder still. Their darkness stretched and stretched with no end in sight, they were unforgiving in their judgment and merciless in their punishment. These were the eyes that didn't hesitate to kill.

But besides those features, it was his age that was glaringly obvious. The newcomer was a teen of all things, barely 17 year of human age. And though the teenager had worn a business suit and had a cane in his hands –in a very, very British style- but it didn't hide the fact the newcomer was a teenager.

The new arrival gave everyone a once over and he didn't seemed to appear impressed. The man snapped his fingers and instantly all the guns that were pointed at him turned into snakes. The men panicked, and why wouldn't they? After all, their trusted weapons had turned into poisonous green snakes.

Nick hissed in anger and took out his other gun and pointed at the man but before he could do any more than that, the man flicked his finger and Nick went flying into the wall.

Seeing Nick flying without wings seemed to have stilled the group and the already tense group tensed further but when Nick ordered to stand down –which was done after receiving a glare from Thor- they relaxed a little bit.

Unconcerned about the tension in the room, the newcomer snapped his fingers again, causing the people in the room to tense further.

The sound of the snap had yet to die when Loki was suddenly thrown on the floor, causing the rest of the room to boil with tension; after all, this was the man that was the sole reason for the hundreds of deaths that had occurred over the world in the past few days.

The unknown man turned towards Thor as he waved his hand unceremoniously towards Loki, causing the fog to swirl and race towards the trickster. As it raced towards Loki and touched the Asgardian, the fog seemed to criticize and solidify, covering the man up and rendering him unable to move; effectively trapping the man in a grave of ice.

The newcomer then tried to sit on air and the fog this time raced towards him, snaking around the newcomer's body and wrapping itself around him. But this time instead of solidifying on the man's body, it began to solidify beneath him, forming a prefect crystallized throne of Ice.

Thor eyed his brother tensely; this was not good, not good at all. The new comer on the other hand, ignored his prisoner as he addressed the God of Thunder, "Is there a reason," He asked the free Asgardian, his voice smooth and calm, as if talking about the weather outside, "that without my permission, there has been a sudden increase in the number of Midgardins arriving in my realm?"

Thor tried to speak, but was cut off by the newcomer, "I don't remember sanctioning any catastrophe on midgard." The newcomer continued as if the god of thunder had not tried to speak at all, "No, I would remember that if I would, wouldn't I?" The newcomer mused absentmindedly.

"God complex enough kid?" Tony Stark asked condescendingly. Well, it might seem foolish for someone to say such a thing, especially when they had been warned by Thor previously, but the thing was that Tony Stark was a man who had faced much in his life –after all, he and some others had just defeated an entire army of aliens- and as such was afraid of even less things.

The newcomer glanced once at Tony and the man began to choke on his own spit. He tried to breathe as he scratched his neck, but it was all to no avail.

"I apologize on his behalf!" Thor said hastily to the newcomer, "He doesn't know who you are."

The newcomer eyed Thor for a moment, a moment in which Tony Stark continued to choke, before ending his hold over the man without even giving the man a single glance.

"Who are you?" It was Natasha who found her voice first. She had, after all, been in many life threatening situations and had an experience in the field.

Thor was the first to answer as he replied quickly, "Death." The god said, "He's Death."

The newcomer -apparently Death- raised an eyebrow at that before asking, "Has Odin not revealed to you my name child?" None missed the moniker of 'child' that was awarded to Thor, and with Thor being as old as he was, it set everyone on edge. According to them -and they were right to assume- either this new character was monstrously powerful or was simply insane to call a grown Asgardian 'child'.

Thor gulped. All-Father had indeed revealed the newcomer's name to him but that name was so simple, so ordinary that it didn't seem to fit the persona that was the newcomer. The moniker 'Death' suited him much better.

"He did." Thor answered and the newcomer kept his eyebrow raised, waiting for the god to speak his name. Thor gulped again and answered, "Harry Potter."

The newcomer nodded before continuing, "Now that it is out of the way," Harry said nonchalantly, "Can you explain, why this pathetic creature," He pointed towards Loki, who was lying on the floor, "was allowed to kill so many?"

"Why you ignorant-" That was all Loki could get out of his mouth before he broke into blood curling screams. Harry remained nonchalant as ever while the rest of the mortals –humans and Asgardian combined- flinched at the sound.

Blood began to trickle out of the tricksters eyes as he cried tears of blood. Thor couldn't take it anymore and begged on behalf of his brother, "Please!" The god of thunder said, "Please stop!"

And Harry did stop. It seemed he had some other plans for the trickster than torturing him to death. "I did tell Odin." Harry continued as if he hadn't just tortured someone, "Frost giants could not be civilized. It's bad blood you see. But he wouldn't listen to me." Harry spoke, his voice as calm as ever, "No, he wanted to give this creature a chance. Huh! It didn't end very well, now did it?"

Though the words had been spoken calmly, but they couldn't have been any more biting and Thor flinched, he could see where Death was going with this and he did not like it. Deciding to be straight forward about it, he asked, "Why are you here?"

"Ah that." Harry said calmly as if he had just remembered something that he had previously forgotten, "You see I was training someone, someone very special. And this pathetic excuse of Life killed him." He told the Asgardian. The truth was that the he had been training someone to take my place and relieve him of his duty. And Loki had killed the man. "I am here to take this creature with me. His actions need… a personal touch from my part."

Loki's blood ran cold and so did Thor's along with everyone present in the room. "Y-you c-can't kill me." Loki stuttered. "I am p-prince of Asgard."

For the first time, Harry turned to look towards his prisoner and raised an eyebrow, "Kill you?" He asked incredulously, "Why will I do such a thing?" He asked innocently, though the malicious meaning behind those words was heard loud and clear.

"Then what will you do with him?" It was Bruce Banner that asked the question.

Harry turned to look at the man and tilted his head in observation, "There are worse things that Death Dr. Banner." He answered offhandedly, "You, more than anyone, should know that." Bruce flinched.

"I request you to let him be tried in Asgard." Thor said with more conviction in his voice than before. "My father will deal with him appropriately."

Harry stared at Thor for a moment –thinking something- and glanced at Loki briefly, the trickster whimpered beneath Harry's gaze, "This thing is whimpering already." He said calmly but to everyone who was listening, the sneer was quiet visible in the voice, "And I haven't even begun yet."

"You haven't even begun yet?" Stark asked incredulously, speaking before he could think who he was talking to, "You fucking reduced him to bloody tears."

Harry glanced at Stark and the man tensed. He raised an eyebrow, as if asking, 'You want another round idiot?'

Stark flinched and fell silent.

"But I suppose," Harry continued as he turned back to the whimpering mass that was Loki, "Dealing with him would be more trouble than necessary." It seemed that Harry had plans for Loki, or else he wouldn't have let the matter rest so easily.

Thor sighed in relief but when he saw Harry reaching for his brother, he panicked. He knew that this man, this Harry Potter, had cursed the man in whose remembrance the screaming statue was made by placing his finger on the forehead and as such he asked hastily, "What are you doing?"

Harry paused and turned to look at Thor with an eyebrow raised, "He's quiet power hungry, isn't he?" He asked calmly, "I was just satisfying his hunger."

Thor's blood froze at those words. He knew just what Harry was talking about. It was the curse of Eternal Hunger. The man that Harry had cursed with this curse before was none other than the man whose fate had shaken the entire Asgard. The man's whose fate had forced the All-Father to commission the statue of the screaming man.

This horrifying curse that Harry had placed on the asgardian had been one of the most inhumane thing that had ever been witnessed anywhere in the nine realms. The man that Harry had cursed had been quite power hungry and he had attacked Harry in hopes of obtaining his power. Harry had cursed him such, that the man from then on, couldn't eat anything except his own flesh.

But that was not all he did, no, Harry had cursed the man by the power of the sun and the moon. By the day, when the sun rose, the man felt a hunger so great for his own flesh that no chain or binding would stop him, and as such, he devoured his own body, eating himself bit by bit, unaware of any pain and suffering except the cursed hunger.

And when the night came, and the moon travelled across the sky, his body would begin to heal. The flesh that he had eaten in the day would re-grow, replacing the wounds. But it was not a peaceful process, no, the re-growing of flesh was painful, as his flesh burned and melted to give way to the new flesh and skin. The man's blood curling screams of agony had resonated across all of Asgard.

If that had been enough, then too it would not have been such a horrendous punishment, no, Harry had again gone beyond that. When the All-Father had taken pity on the man and had ordered his execution, the man had proved to be un-killable, they had tried many things but everything resulted in the same result; the man lived. Harry had refused the soul final asylum. Harry had refused the man, his death.

All-Father had to ask Harry to grant the man Death, for Harry would have let his punishment go for all eternity.

As such, one can understand why Thor's blood froze at the news. "Please...," He asked Harry in a pained and horrified voice, "I will demand Father for the strictest punishment! I will call for the most hideous punishment of Asgard for him! But please, please do not curse him!"

Harry frowned, for the first time showing any reaction, "I cannot let him go unpunished."

"Please...," Thor asked again, his voice terrified for his brother, "Please do not curse him with Eternal Hunger."

All the humans stared at Thor, as the once mighty god turned into a terrified mortal, in front of this Harry Potter. They knew that Thor had said that this Harry Potter was Death, but they had –like any rational being- had not believed such fanciful claims.

Harry smiled slightly, a very innocent smile, "I appreciate your love for your brother, child," Harry told the asgardian, "But I am not known for mercy."

Thor's heart sank; his brother would be condemned to something he wouldn't even wish on his worst enemies. "I'll do anything, anything at all." Thor told the man, "But please, please do not curse him with Eternal Hunger."

Harry frowned and thought on the offer for a moment -while the rest of the room waited with bated breath, even though they did not know what Eternal Hunger was, but by the way Thor was pleading, it was something to be afraid of- before replying, "I shall not curse him with Eternal Hunger, but curse him I shall." Harry told the god, "And you will be in my Debt. Crown Prince Thor."

Thor sighed in defeat; he knew it was the best he would get. "Thank you," Was all he managed to say out loud.

Harry turned towards Loki, who was sniveling and whimpering on the floor from the torture he had received earlier, "You should be grateful of your brother and your father, trickster." Harry told the god of mischief, "He and you, both of you don't know what it means to be in my debt."

With that ominous warning, Harry placed a finger at Loki's forehead and spoke, "Loki son of Laufey, son of Odin," He announced, "The men, women and children that died at your hand, still had long lives to live. The life lost by them, will also be lost by you." At his words, Loki visibly seemed to age in front of them. And given the fact that, Asgardians lived for thousands of years, it was a testament of the number of people killed by Loki that he was losing enough age that it was visible.

Where previously Loki had looked to be in his late 20's, now the Asgardian looked as if he was in his mid forties. Such was the number of years he had lost to the Death's curse.

But Harry was not done, not by long shot. "From this day forth and until you visit my real, you shall suffer the last day of every victim whose death you were directly or indirectly responsible for. You'll feel their emotions; their joy, their happiness; their pain and their end. You shall live it as they had lived and die as they had died."

His curse now complete, Harry lifted his finger and turned towards Thor, "Remind your father," Harry spoke to the god of thunder, "Not to meddle with my vision again. Else he might visit me sooner than he'd prefer." Harry threatened the Asgardian, knowing that his warning will be relayed to the Asgard's All-Father. The man had been messing with his vision, hiding Loki's antics from him, but the All-Father had forgotten, that nothing is hidden from death.

With that last warning, Harry Potter dissolved into a shower of snow and Ice.

Silence stretched for quite some moments before Stark broke it, "Well," Tony said, after a moment, trying to sum it all up, "That happened."

A/N: So, there's that. This was an idea that was nagging me like crazy and just didn't want to leave me alone. So, I decided to write this oneshot. But if anyone wants to continue it or adopt it, they can, just PM me beforehand. As you might have noticed, I have left many openings to exploit.

Love it?

Hate it?

Just review and Let me know!
