* ''Fandoms'': HarryPotter, Smallville.
* ''Synopsis'': Voldemort has been vanquished from power and Harry from Britain. Aiming to start a new life in muggle America Harry moves to what he thinks is a small quiet town to start over. His destiny has just begun. Smallville Xover. Harry Potter/Lois Lane. Begins Season 4
* ''Comments'': Easily one of the best and most realistic crossovers I have ever seen, this one seamlessly blends a postwar, somewhat troubled Harry with Smallville canon. The writing style is excellent, and better yet, it manages to avoid most of the common pitfalls of the genre.

* ''Fandoms'':MetalGearSolid, HarryPotter
* ''Synopsis'': What if Harry Potter got trained by Solid snake at a young age and learns to fight mages and monsters the way Big Boss dose. Guns are included. 'If I ever take over the world I'm making a law against that kind of bubbly happiness...' The man with the eye patch thought.
* ''Comments'' This one is an awesome oddball that's funny, well written and worth a read.

* ''Comments'': Starts off as a basic crossover, but throws a curveball at you when its revealed that [[The Borg assimilated the matrix.]] A recurring theme here is that nothing is as it seems, and ItGotWorse. [[UpToEleven And Worse.]] [[BeyondTheImpossible And Worse.]]

* ''Pairing(s)'': Jareth/Sarah and SS/HG (This story is het).

* ''Comments'': There is a lot of Sarah/Snape interaction, but my most favored part, is the interactions between Jareth/Snape. There's a bit of role reversal, that adds out of character variety to the story. One thing that was brought to my attention, was that I needed to do a bit of research on mythology in order to fully comprehend the story. The last update was in March of 2009.

* ''Fandoms'': HarryPotter, [[http://tvtropes.org/pmwiki/pmwiki.php/Main/Supernatural Supernatural]]

* ''Fandoms'': HarryPotter, Silmarillion

** @/UncloudedTJ: A very interesting take on Slytherin!Harry. It has a deep backstory with some questions (about Harry's past especially) only being answered around Harry's 6th year. It truly shows the ''Sandman'' crossover by including all the main influences from that series but doesn't require you to know anything about them. Overall very well done if you can ignore the spelling and grammatical errors.

* ''Synopsis'': Uncle Vernon thought to bring home a puzzle toy he bought to encourage Dudley's mental stimulation. A box shaped puzzle. A box that plays music. A young Harry solves the puzzle, and alone survives the consequences, to make it quick. Except now he can't stop thinking about the box, about that tune. And he's gained the attention of a very powerful dark being who is ''not'' a wizard.
* ''Comments'': Disturbing indeed. It's a very, very good one shot by itself and you don't have to know anything about Hellraiser at all to enjoy it. The sequel ''[[http://www.fanfiction.net/s/4446981/1/All_Problems_Solved All Problems Solved]]'' is incredibly good as well.

* ''Comments'': An interesting crossover with Firefly where it's believable that Harry Potter existed in the same universe. The story works so well that sometimes it's hard to believe they're not meant to be in the same time much less canon. This is an AU (having been written before HP book 7) so some relationships aren't the same as canon. Other than that the character and plot development is top notch and at about 300k words it's a very well done fic.

** Seconded. It definitely makes you feel that the universes aren't that different after all.

* ''Comments'': This has got to be one of the ''weirdest'' HP fics I’ve ever read that wasn’t explicitly a CrackFic, not because it’s a lemon and not because it’s a crossover with ''LaBlueGirl'' of all things but because it can’t seem to decide whether it wants to be a PWP lemon or a (relatively) serious AU fic for the first five chapters or so before it settles on the latter in chapters 5 and 6. Up until that point, the story flip-flops between the Potter family raising Harry (and his two little sisters later on), Lily/James/Emmy’s bedroom exploits, and [[ForWantOfANail a few loose nails]] that throw the story in a totally new direction once Harry grows up and gets to school, like Voldemort accidentally marking [[spoiler: ''Daphne Greengrass'']] of all people as The Girl Who Lived. Also uses Manipulative!Dumbledore, and Harry's personality is different enough for him to be an OC (albiet an OC who [[ChivalrousPervert takes very strongly after James]]), but I recommend it anyway unless you're fatally alergic to lemons.
** Seconded by @/UncloudedTJ: Quite impressed with the story so far as it definitely does some new things I haven't seen before. If you gloss over the NC-17 scenes of the story it's still a very good fic and deserves some more attention. Slightly annoyed with the Manipulative!Dumbledore but then that's the only complaint so far.

* ''Comments'': Despite being short compared to most of the others on this list, 12 Moves Sideways packs a powerful punch. It's beautiful, almost wistful, with hints of something darker- it might just be because this Troper is a Light fan, but her heart ''broke'' at the Erised scene.
