    Summary

    After surviving his life up to his eighteenth birthday, Harry wasn't really surprised when he got a letter that told him his biological father was Tony Stark.

    Exasperated? Absolutely. Surprised? Not so much.

    He had stopped thinking anything was too crazy to happen to him around the time he fought a fifty feet long Basilisk obeying a memory from a diary with an old hat and a sword. As a fucking twelve year old.

    Already on the search for himself outside of the boy who lived twice, Harry decides to visit his biological father.

    Tony thought after meeting literal gods, fighting against invading Aliens and flying a Nuke through a wormhole into space that nothing could shock him anymore.

    He is, of course, wrong. Trying to house the Avengers is anything but a piece of cake, especially while ignoring his crush on Captain America of all people.

    But nothing tops finding out that he has a son. A son he didn't know about. A son that has the same look in his startling green eyes that Tony recognizes from his own reflection.

    Tony has no idea if he can be a father, especially to someone who looks so lost but he will die trying, that's for sure.

    Summary

    When six-year-old Harry Potter befriends a mysterious crystalline serpent in his aunt's garden, he discovers his entire life has been built on lies. Through a fateful visit to Gringotts, he learns he isn't just the unwanted nephew of the Dursleys or the son of Lily and James Potter – he is Leif Asbjørn LokiThorson, son of Norse gods Thor and Loki, hidden in the mortal world to protect him from both Voldemort's prophecy and those who would exploit his divine heritage.

    With his true appearance revealed and magical bindings broken, young Leif escapes to New York City to meet his real fathers – neither of whom knew they had a son. As he finds his place among the Avengers and learns to control his unique blend of seiðr and storm magic, dark forces begin to stir. While Dumbledore's manipulations and the prophecy loom overhead, Leif must navigate two worlds: the magical and the divine. But with Thor and Loki at his side, along with Earth's Mightiest Heroes, he's ready to forge his own path and face whatever challenges lie ahead.

    Summary

    Holly was so sure she had this whole 'Mistress of Death' thing down. She's at least a thousand years old now and she's had to say goodbye to the same faces over and over again in her old world - she should be used to this by now! But it turns out when it's time for her to go to a whole new Earth that's only similar to the one she left on the surface and she has nothing familiar to turn to or lean on - Holly realizes that being the Mistress of Death can be so, so much harder than she ever thought it would be.

    She's arrived right into the thick of the Chitauri Invasion of New York and meets all six Avengers as she pops around the battlefield helping out - saving civilians and assisting the group of heroes, hoping that since they're, you know, saving the world they'll be nice and help her integrate into her new dimension. Thankfully she's correct and the Avengers are quite happy to induct a seventh member - but what happens next? How does the plot of the MCU go with Holly Potter, Mistress of Death, lending a hand? And is she going to make things better?

    Or will she make them so, so much worse?

    Summary

    My take on the Tony is Harrys Dad trope.
    The fiasco that started on the graveyard leads to some starting revelations. Despite technically not being a Potter anymore, the Potter Luck is running the show. A still recovering and traumatized Harry shows up on Tony’s doorstep hoping his superhero father can change the course of the war.
    Harry’s past tells him none of it is going to work out. Tony’s past have given him every reason to believe he will be a terrible father.
    Will they both be proven wrong and get the ending they deserve or will it all go up in flames as they both expect?

    Summary

    Tony Stark had never imagined himself as a father. He could barely keep himself alive as it was.
    Plus his life was too chaotic, I mean aliens, terrorists, intelligent robots (that he practically created but whatever) wanting to conquer or destroy Earth—there was a lot to handle.

    But one day, his already crazy life changes when an owl deliveres a letter, revealing that he has a son.
    If he thought his life was chaotic before, he had no idea what it would be like to be the father of one Harry Potter, aka The Boy Who Lived.

    How do you deal with the fact that there's a prophecy about your son and that a crazy, bald snake face wizard is after him? Asking for a friend, because that certainly doesn't come in parenting books. Sincerely, Tony Stark.

    Summary

    Hand on the throttle
    Thought I caught lightning in a bottle
    Oh, but it's gone again
    And it was written
    I got cursed like Eve got bitten
    Oh, was it punishment?
    - The Prophecy, by Taylor Swift

    Lily Evans lost her twin sister, her other half when she was stolen away from the family at five years old. At twenty years old, she gives birth to a little girl that shares her eyes; her sisters eyes.

    Fifteen years later, Natasha is holding a file in her hands and reads the name Harriet Clara Evans, sat beside a picture of herself at five years old.
