All According to the Master Plan by TardisIsTheOnlyWayToTravel reviews
Harry is taken in at a young age by a psychopathic Time Lord planning to conquer Earth using the wizarding world, and his human wife. It’s a very different Harry Potter who comes to Hogwarts. Harry Potter/Doctor Who crossover. Crack-ish.

Mission Accomplished by mizukiryu73 reviews
There is a reason hawks are kept hooded before the hunt. For you can clip their wings and hobble their feet, but they are hunters true. And they are loyal only to those who respect that, to those who earn it. Because they are always, always dangerous.

When The Shadows Howl by NoitavlasCross reviews
Loki's punishment was to live in Midgard as mortals do, without the aid of magic. Through Thor's pleading, Anthony Stark provided Loki a place to stay in while he serves his punishment. Friendships develop, family reunites and a whole new horror awaits-and it starts when Tony accepted an invitation to a business trip in London, dragging Loki along with him. Non-Slash.

What Makes a Man by The.Evil.Overlady reviews
Harry moved to America to start afresh, to put the war behind him, move on and become a journalist. Shame the universe would always conspire against him. This is the story of how he met the Avengers and his life was turned upside down. Again. Rated T for future language. SLASH but no pairing yet.

Not as Grimm as it Seems by Whispering Darkness reviews
For a moment Harry started, surprised at the first sign of any sort of non-muggle presence in this world. Just what exactly was a 'Blutbad' - or a Grimm for that matter? Collection of related drabbles/snapshots centered around Harry, Monroe, Nick and Renard.

Bite Sized by SlipStitch reviews
The first time that Harry met Tony Stark he was just about to close his little bakery shop, Bite Sized. The second time Stark came to the bakery he brought along a pretty redhead that had a phone stuck to her ear and seemed to be trying to placate someone on the other end of the phone. Tony/Harry. Slash. Drabbley.

The Wicked Witch in the West by Argonaut57 reviews
Life is complicated enough for detective Nick Burkhardt without someone randomly killing a harmless Maushertz. Matters are not improved by the arrival of two British cops in Portland. DCI Harry Potter and DI Ron Weasley are not, Nick feels, quite what they seem!

Of Hel and Earth by Ocearna reviews
When Luna appeared on Harry's doorstep one evening with a job offer from the Unspeakables, Harry decides a change of pace is just what he needs. Getting dumped in a certain alien-ravaged city in an entirely different dimension is not what he signed up for. Post-Avengers (2012), very post-HP AU.

Tal - Maqluba by Astorian reviews
Harry Potter messed with something he shouldn't have, now he's in a world with pushy Avengers, people after his magic and oh he looks like a preschooler. Should have stayed away from Malta...

If You Don't Believe, It Might Still Find You by RoseFrederick reviews

Brilliant Blood by wickedlfairy17 reviews
A letter, just a few lines on a piece of paper, and it was enough to change the entire world. At least Tony's entire world, now he couldn't imagine ever going back. He loved being a dad.

He's not a Demigod anymore- he left that aspect of his life behind a long time ago. Now he's an agent of SHIELD. With his past haunting him and the Avengers attracting trouble Percy Jackson is about to find out what it really means to be an Agent of SHIELD. Angst! Slight character bashing.

Not Just Fairy Tales by LadyNyxRavus reviews
The man's eyes widen and he brings a hand to his face and Harry gets the feeling that perhaps he isn't supposed to be seeing that fur. Although that makes no sense because it's RIGHT THERE.
