Story Notes: The prequel to this story, Harry Potter and the Power of Love, is not even close to being finished, however enough chapters are in that story now to provide the necessary background. A couple differences from MCU canon:

In the movies it's supposed to be that it took every avenger to win. So adding harry in means that it will be in my story that WITHOUT HARRY THEY WOULD NOT HAVE WON. So the good guys will not be getting a lot of those lucky breaks and for many situations the bad guys will be attacking more realistically harder and smarter; in other words, THE ENEMY WILL ALWAYS BE MORE DANGEROUS AND POWERFUL THAN THE MOVIES PORTRAYED(I like to go by every action has an equal and opposite reaction; add harry to one side you need to counterbalance that). Also, the addition of the Wizarding World to the universe needs to be noted.

The timeline prior to this story for the MCU I will alter so it makes a bit more sense. Marvel keeps changing their own timeline and directly contradicting what their biggest characters say in the movies and in info dumps how much time has passed. Also, expecting us to believe the avengers did nothing(believe me I've looked everywhere for info on this) in long stretches for multiple years at a time is preposterous.

Harry is the glue that holds the Avengers together. He is also extremely vulnerable, as a team of special forces could dispose of him with the element of surprise, with ease, so he is more a support character with immense power and always surprises. without him the Avengers will fight among each other and evil will win.

Harry will NOT, EVER be a super mega OP character in this story. Thor and Hulk, and you could even argue Iron Man depending on the situation(and armor), are more powerful than he is, and vibranium I plan on being kind of like kryptonite to magic. No magic works against vibranium, so Harry would have huge trouble against someone like say Black Panther. I find it ironic that one of the easiest people to beat for Harry would be one of the most powerful, Scarlet Witch.

In the Avengers movie Loki and very slightly Cap will both be stronger. Cap because he was weakened by the ice significantly(and we didn't see him not weakened until WS) but more time has passed and already training again to fight in this timeline, and Loki because I'm having that wielding an infinity stone will strengthen him like it did Ronan in Guardians of the Galaxy. Also, Loki will even without it be slightly more powerful than in canon. The Chitauri invasion will be more formidable because they are fucking alien invaders that Asgard feared and really as soon as they were being beaten back they would send a lot more firepower in faster.

This story will be from the first person view of Harry, so the story won't be looked at the way a movie goer sees it, but as Harry sees things. This means he can and likely will make wrong assumptions about what's going on.

Harry is a confident but haunted person, more lively than movies and books at this point in time, wiser, and his voice isn't like a part whisper half the time lol, but still a teenager nonetheless.

There will be no Harry/Tony, Harry/Steve or any of that bullsht! Just because Harry is an Avenger doesn't mean he has to get in a marriage with multiple avengers at the same time when clearly none of them are pedofiles, gay or attracted to each other. Just don't, please don't. It is so disgusting, especially when you consider we are talking about a sixteen year old whose girlfriend was murdered recently. I do have someone planned for Harry, so chill.

Nick Fury is... well, you'll see actually:)

I will deviate from canon as much as is realistic and of course to buff the enemy, but please note that a lot of things would stay the same, and you will be surprised like me how much of the movies we've forgotten about.

Preview: How Did I Get Here?

I was being tortured in the graveyard, Voldemort's haunting laughter washing over me….

The Department of Mysteries, Daedelus Diggle's decapitated head spraying brains upon me as the body thunked to the floor….

The kidnapping in the Forbidden Forest, rushing to save my friends….

At Stonehenge alone, standing up to Voldemort to protect everyone….

An entire large town wiped out and zombified by Voldemort, forced to destroy it to protect the Statute….

Breaking into Gringotts, being banned forever by all goblins and abandoning Wizarding Britain….

Nurmengard, holding his newborn Godson Teddy in his arms, more precious to him than anything else….

The beaches of Normandy, over 50,000 Inferi storm towards he and Albus, his mentor, his greatest protector giving his magic force to save us all….

I'm pointing my wand once again at Severus, the man I once despised but who must die to secure our plans for victory, the Killing Curse rips from my wand and speeds towards him….

Egypt, trapped in a tomb with Bill, an endless sentient Labyrinth refusing to let us leave….

Devils Tower America, I stand upon the rim, Matthew blocking my passage to stop the evil from being unleashed….

Virginia, America, Nick holds out a special black cellphone with a magic suppressing rune imprinted on top to me as I, he and Steve stand over Matthew and his helpers' dead bodies, with the bombshell that Nick's brother is Kingsley….

The city of Mainz, Germany, a fleet of ships carrying enemies spilling over, a swirling cloud of fog encircling the city, Moody, Sarah, many others dead….

Assaulting Azkaban, blood drips down the walls as I lead the attack…. So many dead….

The wharf, facing down the injured Voldemort with nowhere for the bastard to run… but Ron, Hermione, and Susan follow against my orders, before I can react Voldemort yells Avada Kedavra…. A scream of pure agony is ripped from my throat as waves of magic emanate from me, I obliterate Voldemort, but the cost... was too high….

Those I failed are grabbing my shoulders, shaking me apart….

"Harry… HARRY!"

I stop screaming and sit bolt upright before Sirius engulfs me in a bear hug, patting my back and whispering to me. He is the only person who can do that without me flinching away. My entire childhood physical contact meant awful pain, and that's all I knew until I was hugged by my best friends. That's what makes Sirius even more special than he already is to me. A mentor, father, older brother, guardian angel, uncle, and best friend all rolled into one.

"It's okay Harry, it's just a dream, Teddy and I are still with you Harry…."

I groped the bedside table and finally found my glasses; putting them on, Sirius with baby Teddy in one hand come into focus. Hedwig, my phoenix, who to muggles is glamoured as a parrot for the moment, flutters over and nuzzles my face comfortingly. I stroke her back softly and thanked her.

"I'm so sorry Sirius," I whispered, "Did I wake Teddy this time?"

Sirius shook his head. "No you didn't kiddo, and I'm getting tired of telling you to not be sorry for having nightmares. You need to work out what has happened." I nodded numbly. "What time is it?" I asked.

"6:30 in the morning, but we'll reach New York within a couple hours. Why don't you get dressed and take Teddy while I get breakfast. That sound good?" I agreed and after throwing on some clothes(permanently conjuring ones was too draining) I took Teddy and stood on the front deck of the cruise ship.

I looked out across the dark blue-green ocean to the distant city of New York from the ferry, the wind rustling my mussy black hair. In my arms I clutch Teddy tighter to me.

It has been a month since I defeated Lord Voldemort. A lot has changed since then, but that is the way of things I suppose. As long as some things are equally unchangeable… gah! Even inside my own head I sound like Albus!

The price was too high. That is the summary of what happened. The. Price. Was Too. HIGH! I close my eyes and take several deep breaths before I lose it and endanger Teddy, or Sirius who is also on the ship. Not to mention the thousands of other innocent muggles aboard.

Accidental magic almost never happens beyond the age of nine and ten, but my childhood was so agonizing that the rules, as always, don't apply to me. Being beaten so bad even my magic could not heal the worst scars, not to mention the slave labor or trying to survive when on the streets on other days will do that for you.

And don't forget the evil Dark Lord destroying all I hold dear. Almost forgot about that! And I'm still only sixteen!

Yeah, my life is shit.

Teddy and Sirius… they are EVERYTHING to me. All that I have left. The rest was taken from me. Parents, My friends, family, peaceful sleep, childhood… anything I can think of was taken from me.

Except for them. And I will protect them even if I have to burn the world to do so. Oh, and I can do that pretty well too.

I am a soldier. I considered using the term was for myself but decided that I still am one. Going to America… yes, we are leaving the Wizarding World behind but I will never stop fighting. It's who I am, I need to fight and defend others. My hero complex, as Hermione once told me….

No, I thought, I must not think about her… about them….

"Hey Harry, I got breakfast," Sirius said behind me; refocusing my eyes we sat down and ate watching the newly risen sun wash over the rapidly approaching buildings.

"So what's our game plan once ashore?" he asked.

"Well we won't need any jobs, considering the expanded trunk full of money we have," I answered wryly. Most of the money is already converted to American dollars. "First we should get an apartment for ourselves and lay low from MACUSA. Tracking down the dark wizards should wait for a bit - easier to get them once they gather together again."

Sirius thought about that for a moment. "Yeah, seems solid," he affirmed. "Lets just enjoy our time with Teddy for now. Despite your love of fighting you don't need to be a Commander all the time." I nodded and we stared out in silence upon New York, each lost in their own thoughts yet enjoying the company of their last and closest comrade, and more importantly, true family.

Upon disembarking we walked out with our luggage our charms keeping the muggles from noticing us. Indeed, there would be no remembrance of me, Sirius or Teddy ever being there at all.

Normally wizarding governments could track the general area where magic was performed, and with MACUSA super paranoid doing with the fact that they were in New York City, would get them arrested in moments. But Albus as always knew the perfect spell, and thus their magical presence was obscured from magical detection. Sirius though after the war decided to lay aside his wand for the most part, just focusing on supporting me, raising Teddy, and perhaps get a job.

I will always go after any dark wizard and gladly accept a fight against an evil being. However, I had made a final decision; my future, whatever it might be, was not to live with the Wizarding World.

But the biggest issue he had was I need the purpose of fighting the good fight. I cannot continue like this. It just feels fundamentally wrong. And I see the faces of those I've failed looking at my so accusingly... I shake my head as Sirius and I hail a cab.

"Something bothering you Harry?" Sirius asked.

"I need to be out there helping Sirius," I told him sadly. "It's my duty." Sirius let out a short bark.

"I wouldn't sweat about it pup," he said jovially. "With your luck, we'll have them lining up for you on the streets!"

"Don't jinx us Sirius, now the whole city will be burned down." I muttered sarcastically as we climbed into the cab.

*Three days later, no more no less. Three shall be the number of days between words, and the number of the days shall be three. Four days shalt not be between, neither shall be two, excepting that thou then proceed to three. Five right out, as is one. Once three days, being the third day after, be reached, then:*

"MERLIN DAMMIT SIRIUS YOU DID IT AGAIN!"
