With his friends dead and almost nothing to keep him in England, he sets off to discover the truth about these 'Cold Ones' and how the poor muggle girl got involved with them.

Summary
Harry Potter was very lonely. Yes, he had friends, a good job, and just finished his mastery in defense, but it was usually just him and his son all alone at night when everyone else had families and lives apart from them. When he learned by chance that he may actually have some living family, it should have been an easy decision to reach out to them. Unfortunately, nothing comes easily to Harry. Harry's biological father just had to be the most difficult person in the world to get a meeting to see, and the absolutely most suspicious when confronted with a paternity claim.
Tony Stark was very lonely. He and Pepper had recently broken up. His friends had betrayed him, and he was now forced to live with the very same people who had hurt him. He didn't think he could take one more blow and stay standing under it. Tony didn't have family; he didn't know what to do with family; too bad Tony's family wasn't sure what to do with him either, but they were going to give it a hell of a try anyway.

Don't think about it and it will go away on its own by Gimlili

Summary
He didn't want to be Harry Potter anymore.
There was nothing left for him in the wizarding world so he was starting over.
Harry Peverell, a 17-year-old muggle with too much time on his hands, moves to the only place where he might still have family.
Forks, Washington, seems like the perfect place to start over and carve out a new place for himself but he's not the only immortal teenager in town and ignoring the problem doesn't seem to be making it go away.
He didn't need to get involved with every supernatural mystery, and really, was it any of his business if his new cousin's eyes glowed amber sometimes? It certainly wasn't any of his business that a coven of vampires were pretending to be teenagers at his school.
Harry is determined to ignore what's happening and instead focus on his hatred of Charles Dickens, Chemistry homework and Mike Newton.
But the supernatural element of his new high school can't seem to leave him alone and Harry has always been really bad at staying out of things.

Summary
Dying and coming back to life for a second time should have been more surprising. Harry Potter merely sighed in exasperation and moved on.
Death at thirty was not something he was entirely happy with, but he had lived a lot longer than he could have hoped for at fifteen years old. Waking up after was annoying, but in such a chaotic situation he could only roll with it.
Having a wizard with a whisper of Destiny about him wondering about Harry's existence in this wild new world was bad enough, but to these people he was considered a child. Nope, he was not going to be staying with them.
Harry Potter had not been a child in a very long time; he would not start acting like one now.
OR
Harry Potter crashes into the Company of Thorin Oakenshield in Goblin Town, finds out he’s now an elf-child, coming back to life after death is a fact of elf-life, Music equals Magic, and dark lords are a universal constant whenever and wherever magic is involved.

Summary
Harry thought it was rather odd how few lies he actually told. You would think a wizard living in the middle of muggle New York would lie his arse off. But he didn’t think he’d once lied while explaining something magical to a muggle. Sure most of the time he came off as a complete and utter prick. It was also hilarious because no one ever believed him. He was a regular Luna Lovegood!

Summary
"Let me take him," Loki said in a quiet, tight voice. "I'll come with you willingly, but let me carry him."
"Why?" Tony asked curiously, even as the Captain was shaking his head to say no. Asking questions had gotten Tony where he was in life, after all. That, and it couldn't hurt to get a little insight into S.H.I.E.L.D.'s newest extraterrestrial capture before they brought him on board the jet to return to the helicarrier.
Loki's eyes were still trained on Hardin in Steve's arms as he answered Tony. "Because he dislikes being touched by strangers." Then, as if agonised by the word, he gritted out an irate please that made Tony's eyebrows shoot up behind his mask. It was telling that a man who seemingly viewed humans as lesser was willing to plead with them for any reason, solidifying Tony's theory that Hardin was very important to Loki further.
Or; the one where Loki isn't alone at Sanctuary, doesn't particularly want to subjugate humanity, but will do just about anything to keep Hardin safe from The Other.
