Summary
Alec is half shadowhunter half warlock. First time he showed his warlock mark was when he was only 5 years old. His parents disowned him and portaled him to the London and let him on the street to die.
Few days later Ragnor Fell sees demon attacking him and there is a shield around the little boy. Ragnor kills the demon and takes him home and decides to raise him.
15 years later thanks to his dad (Ragnor) Alec is embracing who he is. But one day he finds his dad’s house broken into and Ragnor nowhere in sight! And now some shadowhunters and warlock is searching for Alec saying they need the book of the white (because he is the one who hidden the book). Yeah, good luck finding it because he trusts NO ONE, especially not Shadowhunters!

Summary
"Life is a cruel and twisted game. Peter learnt this at a very early age. Consistently, every good that he experienced was found to be temporary, eventually ripped harshly from his grasp the second he began to believe that the happiness would have no end. Pain, however, that stayed- lingered in the shadows wherever he went, waiting for the perfect moment to jump out and embed itself into his skin. It became a part of who he is, and although he would never admit this out loud, he found its presence comforting.
The one thing Peter still genuinely found joy in was Spider-Man, it was the only time where his carefully curated persona felt less... well fake. So, swinging through New York, listening a playlist filled with his aunt and uncles favourite songs, on his earpiece that he made a few months, was probably one of the best parts of his day."
Or,
Peter hasn't had an easy life, losing all his family and friends, and being forced to fend for himself. However, one day a strange man walks into the garage he works in asking Peter to fix his metal arm... Unknown to him, this was the begging of a new era- filled with the best type of chaos (and occasionally, the less good kind). -

Summary
Nick Fury looks down at the file of one Perseus Achilles Jackson and is silent while he thinks. Percy, as he preferred to be called, Jackson had been recruited into S.H.E.I.L.D. shortly after he turned twenty-one. Before, he had worked in the World Security Council’s Hazardous Search and Rescue Division. The boy had joined weeks after he turned eighteen and rose the ranks in record speed, and by the time he turned twenty, he was in charge of his task force.
Now he’s twenty-seven and after six short years of being part of S.H.I.E.L.D., he was already a level seven, one of the best agents they had, right up there with Romanoff and Barton.
Yes, Fury thinks, He’ll be good for the Avengers Initiative.
“Tell Agent Romanoff to call in Agent Jackson, and tell him to pack all his shit for at least three weeks” Nick called out to the AI.
“Yes, Mr. Fury”
