Harry Potter - J. K. Rowling+2

Of Wizards and Heroes

by storyforsomeone

Centuries after that fatal day of the battle of Hogwarts, Harry Potter has fallen into legend, a bedtime story parents tell their children, a name whispered around campfires. He wanders the world alone and immortal, until one single reckless moment sends him hurtling into a parallel dimension of heroes and villains. A new enemy arises from an ancient power, and Harry must take a stand as the last wizard to protect this new world. If only SHIELD would stop trying to track him down...and someone could explain what the hell was an 'Avenger' was supposed to be. Honestly, muggles...

When we're together (I'm not afraid of my tears)

by Must_have_been_the_wind

The internet is a powerful tool, news spreads quickly across the globe- sometimes faster than it can be taken down. So what happens when a live stream starts from the infamous city of Yokohama, what happens when two teenage boys ruthlessly execute a Pro Hero to serve as a warning to the outside world on camera? What happens is an overwhelming demand to apprehend these boys and see justice served, however, one crafty principal has another idea in mind… Or, Dazai and Chuuya are “forced” to attend UA after killing a Pro on a live stream. (But does it really count if it was their plan all along?) (Check beginning AN for translations into Русский, Español, Tiếng Việt, Íslenska, Français, Português brasileiro and a podfic!)

Road to Nowhere

by Aerugonian

Hitoshi knows there's something wrong with himself before he's even old enough to have a sense of self. He looks at his reflection and knows that the infant looking back at him isn't what he should be seeing. His dreams are a maelstrom of grief and fear, his mind overwhelmed with a lifetime of emotions his brain isn't developed enough to comprehend. There's an ingrained instinct blaring that everything is wrong wrong wrong. -- In which Hatake Kakashi is reincarnated as Shinsou Hitoshi, and he wants nothing to do with this world's so-called "heroes." Podfic available!

Edo Tensei

by Asteroid_Duck (JustThatOneGirl1815)

“The HPSC is doing what?” Present Mic asked Nedzu incredulously. Nedzu’s smile was tense. “The HPSC is concerned about the recent attack at the USJ and are choosing to intervene. A student of theirs will be transferring into Class 1-A in order to watch for a potential traitor in the school.” . . . Or, Hatake Kakashi is reincarnated into bnha with a quirk that makes even All for One look like child’s play. And in his eyes, anyone in UA could be the traitor he’s looking for.

Harry Potter and the Immortal's Playground

by May_May_0_0

It starts slowly, the steady disconnect between who he is and who he should be. The man in the mirror becomes a stranger to him; he looks into the glass and wonders how everything became so distorted and backward and...wrong. He notices in bursts: when Teddy grows taller than him, when he’s kissing Ginny on her lips and looking at the subtle smile lines she’s starting to develop around her plush mouth. She’s got the cutest crinkles by her eyes. His face is smooth as it was when he was seventeen. Which was 18 years ago. He hasn’t aged a day. _________ Living forever isn't all it's cracked up to be. Harry Potter learns the meaning of immortality when everyone he loves dies again and again after becoming the master of death. After millennia of love lost, Death sends him to "Elsewhere" in order to give his master something new and different. Harry emerges from ash in New Asgard. What's a man like Thor to do but offer the traveler a home?

You're Not A Horse, Harry!

by Maeglin_Yedi

“So you’re my dad,” Harry said to the large, blond one. The one with the hammer. Supposedly a god, even. “Yes, I have conceived you myself!” His ‘father’ said with a huge, beaming smile. “With your brother,” Harry said very slowly, very carefully. “Who is apparently my mother.” Harry gave the tall dark-haired one a good, long look. Yes, there were similarities between their features, even Harry could see that. Hair, eye-colour, the shape of their nose and mouth. In which Harry is the product of a prank that Loki once played on Thor. But hey, at least he's not a horse, so there's that. A series of vignettes about Harry's life with the Avengers while getting to know his new parents.

All Hallow's Eve - New York

by WhisperingDarkness

Harry Potter had never really managed a normal, peaceful Halloween, so he really shouldn't have been surprised when he was suddenly displaced from the grocery store and found himself in front of a maniacally cackling man in a very dramatic outfit.

None So Blind

by prettybirdy979

They say when you assume you make an ass of you and me. Matt wishes that the Avenger's assumptions about his seeming inability to read the written word did something as benign as making an ass of him and them. Being called illiterate shouldn't hurt, not when he knows he's not, and it's not like he can tell them the truth. Not that the truth would make much difference. He's just going to have to grin and bear it. If he can.
