When Harry and Cedric grasp the cup, they think that this will mark the end of the tournament. Instead, the portkey transports them to Little Hangleton. Now, Harry had been in similar situations before; the adventure at the end of the school year was a given by now. What he really hadn't expected, was travelling in time - and with Cedric of all people! WW2 epic - Grindelwald's war

Harry just wanted a moment of peace. He didn't want any trouble. But in typical fashion, he falls off a quidditch goalpost and a concussion later he's seeing visions of Merlin's life... or is he just finally going crazy? Harry-is-Merlin reincarnated. Druids, Mordred, Arthurian legend reinvented. Oh yes, and a few dragons.

During the Yule break of his Sixth year, Harry relives a memory that has been long forgotten. A memory of Merlin's childhood.

Sherlock is investigating a murder in Privet Drive when he meets Harry Potter... And apparently he's his son. ON HIATUS. STORY BEING RE-WRITTEN

What if at 'The End of Time' episode, instead of being sucked back into the Time-War, the Master fell through a crack in the universe and ended up on an alternate earth, memories erased, and transformed into a baby? What if he was then adopted by the Potters and named 'Harry Potter? What if he then discovered who he really was? What if the Doctor and Clara followed him soon after?

The story of how Harry Potter left the wizarding world, only to become the muggle version of a Dark Lord. The story of how he became a manipulative bastard. The story of how he became James Moriarty. Machiavellian!Harry

Sherlock untersucht einen Mord im Privet Drive, als er Harry Potter trifft… und anscheinend ist er sein Sohn.

Harry has had a pocket watch for most of his life. He doesn't know where it came from, why he has it, or why no one ever seems to notice it. He does know one thing however... It bares a similarity to the one used in a show called Doctor Who... Timelord!Harry, Doctor!Harry, Good!Hermione, Good!Ron, Bad!Dumbles... Pairings to be decided later. Most likely Harry x Rose. Enjoy!

In a surprising turn of events, Harry is sorted into Slytherin. Here he has to adapt to the manipulative and often ruthless cutthroat attitudes within the house.

(Features a powerful Harry, eventually Dark!Harry, eventually charismatic, character development)

Years after Harry ended the war and landed himself a position on Hogwarts' staff, he is attacked by one Lucius Malfoy. The magic backlash causes Harry to go somersaulting into a dimension 70 years in the past before Dumbledore ever defeated Grindelwald. Now Harry has to face juggling Hogwarts students, another Dark Lord, a new prophecy and a flirty Transfiguration Professor. HP/AD

Oneshot: When Harry and Ron see the Ford Anglia for the last time during their second year, they never thought that they would see it again. But now, years later, during the Battle of Hogwarts, the very same car comes to Harry's rescue during his face-off with Voldemort. Inspired by a tumblr post.

After ten years, Voldemort was finally killed, thus ending the Second Wizarding War. Since then, two years on, Harry has become a politician.
