* Recommended by User:Schizo Technician, User:Doppelganger 511, lindabhair
* Crossover with Pokémon.
* Synopsis: Late in his second year, Harry Potter takes an animagus potion. His animagus form is Mew. Hilarity Ensues as he discovers catnip, learns what his new form can do the hard way, and tries to find out what the hell he turns into, anyway.
* Comments: Surprisingly well done, given how easy it would be to take this down the wrong road. Very little from Pokémon appears -- no attack names, no pokeballs, nothing except animagus forms, without even any knowledge of what they are or do. Hilarious at times.
* User:Doppelganger 511: I second the recommendation. I usually loathe crossovers, but this one is fantastic. Definitely worth reading.

* Crossover with Digimon Frontier.
* Synopsis: For five years, the kids of Frontier have been training as Japanese wizards. Now they've got the chance to study abroad, in England of all places. But there are some odd things happening. Digimon...at Hogwarts?
* Comments: Don't let the title fool you, inspired by The Best Defense, this is one of the most thought out crossovers you are likely to find, everyone is in character, and the plot makes perfect sense. Path of Decision by lulu42 (contains mild violence.)
* Recommended by Fenro, User:Unclouded TJ
* Crossover with The Sandman.
* Synopsis: Voldemort is in power, but the Wizarding World fights back. Harry Potter, Master of Death, is faced with a choice: move forward or change everything?
* Comments: The plot is very intriguing, but there are a lot of spelling and grammar mistakes. This story takes place during Harry's Hogwarts years. This story is complete. Invert by Marz1
* Recommended by User:Comartemis, User:Rogue 7, Fenro
* Crossover with Fullmetal Alchemist.
* Synopsis: While investigating a bizarre alchemical structure, the Elric brothers get pulled into the Potterverse early on in an AU version of Deathly Hallows. In the interest of finding a way home, Ed lends his talents to the Horcrux hunt while Al finds ways to keep himself busy at Hogwarts. Better than it sounds.
* Comments: This was the fic that originally got me interested in FMA. It doesn't measure up to fics like Harry Potter and the Nightmares of Future Past or Dumbledore's Army and the Year of Darkness, but it's still an entertaining read. Seems to be a deadfic but the first half of the story is complete enough to enjoy as a stand-alone fic.
* User:Rogue 7: Amusing and well-written, though, as stated above, not one of the best. Worth reading simply for how in-character Ed is. Cerulean Silver vs Amber Gold by hikaranko
* Recommended by eagle108
* Crossover with Fullmetal Alchemist.
* Pairing(s): Draco/Hermione
* Snyposis: Edward Elric gets assigned ...to babysitting Draco Malfoy, at the request of the British Ministry of Magic. While Ed considers the assignment stupid, having to spend an entire year undercover as a student at Hogwarts, there's a lot more than what he was told during briefing.
* Comments: Excellently written, spot-on characterization, even with the deviations in the HP world. While the gradually built Draco/Hermione romance occurs in the background rather subtly to Ed's interactions with the HP cast as the main focus, it nonetheless has a strong and supportive impact in a whole to the story. Shades of Draco in Leather Pants is featured, but it's done quite tastefully. Ed here has a few "magic doesn't exist/magic breaks the laws of alchemy" moments but it's far and few in between, and he does comes to explanations that could work between both verses. Dangerous Gifts by SGCbearclub
* Recommended by Fenro
* Crossover with Labyrinth
* Pairing(s): Jareth/Sarah and SS/HG
* Synopsis: Snape never asked to be rescued. Sarah never asked for magic. Jareth doesn't generally ask, period. The Ministry should have remembered that, back when they assumed they won the Goblin Wars. Nothing is ever what it seems. The story takes place after DH but without the epilogue. Labyrinth crossover.
* Comments: There is a lot of Sarah/Snape interaction, but my most favored part, is the interactions between Jareth/Snape. 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. This fic is rated M for Sexual Situations, Suggestive Themes, Violence, and mild-language. The last update was in March of 2009. Fusion of Destinies by Grey-X

* Crossover with Metroid.
* Synopsis: A blazing meteorite falls into the forest around Hogwarts, leaving an amnesiac woman called Samantha. Working odd jobs around the school, she finds herself drawn to Harry. But she's here for a reason: A terrible spell that has called forth a weapon from the future... and the one person that can stop it. Crossover with, of all things, Metroid.
* Comments: Seconding by User:Sparky Lurkdragon, who's actually coming at this from the other side: Harry Potter really isn't my thing, but I love Metroid. I'd just like to vouch that Grey-X delivers very well on the Metroid side of things, too; in particular, it's very refreshing to see a ficcer acknowledging that Samus is probably more Chozo than human, culturally.

* Crossover with Once Upon a Time In Mexico.
* Synopsis: "We all need someone we can lean on..." Two unlikely men in an unlikely place find an unlikely friendship in each other. A post-DH, post-Once Upon a Time in Mexico crossover AU featuring Severus Snape and Sheldon Sands.
* Comments: Yes, it's a Harry Potter, Once Upon a Time in Mexico crossover. No, I have no idea how that idea came about. Yes, it is pretty awesome.
* Seconded by User:Skazka, who literally stayed up overnight without sleeping to read this fic the whole way through. A warning is due, though-- as in some of the author's other fics, Sands is occasionally fond of manipulating people using sex, and Snape is no exception. Still, I wouldn't call it an outright slashfic. Perhaps with the exception of much of Chapter 11.

* Crossover with Hellraiser.
* 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. The sequel All Problems Solved is incredibly good as well.
* Comments:
* Arguably one of the best psychologically frightening stories ever. I had goosebumps reading it.
* FrodoLives: Extremely creepy. Gives sufficient background so that it still will make sense to people who have not see the Hellraiser movies, like this troper. Best punishment for Fudge and Umbridge ever.
* IraTheSquire: Holy crap. Most. Deliciously. Disturbing. Thing. Ever. Read this if you are Harry Potter fan. Read this if you are a Hellraiser fan. Hell, read this even if you know nothing about neither. This guy knows how to write psychological thrillers and I can assure all aspired writers can pick up a thing or two from reading this.

* Crossover with Buffy the Vampire Slayer.
* Synopsis: In an alternate summer after the events of Order of the Phoenix, Harry and the Dursleys are moved by the Order into an apartment when 4 Privet Drive is identified and targeted by the Death Eaters. Harry finds little to recommend the change until he meets the gentleman living in the next apartment -- one Mr. Rupert Giles, whose quiet and respectful friendship saves Harry's sanity and soul from the depths of despair.
* Comments: Set after the final episode of BTVS and featuring almost none of the other characters from the series, this is a low-key story that nonetheless carries an unexpected emotional intensity, all the way to its quietly surprising ending. Browncoat, Green Eyes by nonjon

* Crossover with Firefly (post-Serenity)
* Synopsis: Two years have passed since the secret of the planet Miranda got broadcast across the whole 'verse in 2518. The crew of Serenity finally hires a new pilot, but he's a bit peculiar.
* Comments:
* User:Dor: Seconded enthusiastically. Nonjon mostly writes comedy, which is a shame because this story proves he can write "serious" fic to rival anyone else mentioned on this page. There's definitely more than a few laughs in there, too (Chapter Four in particular is just one after another), but unlike the rest of Nonjon's work, there's more going on in Browncoat than just the comedy.
* User:Comartemis: I know absolutely nothing about Firefly but I had a blast with this fic anyways. It bears noting, however, that Harry appears at first glance to be massively out of character until certain details regarding his past are revealed later on in the story, namely the fact that Harry spent a bit more than a century married to Luna Lovegood of all people (You hear that noise? That's the sound of everyone who's ever read that far going "Oh, that explains it."). Of Gods and Men by shadowphantomness

* Recommended by melloncollie
* Crossover with Naruto
* Synopsis: This fic is an Itachi-centric crossover with the Potterverse. While an ANBU captain, Itachi is called away to Britain on a mission as Harry Potter's covert bodyguard. Hilarity Ensues.
* Comments: This fic could use a bit of polishing, but if you can overlook the numerous grammar and spelling errors there are a few genuinely touching moments, brought on by the "what-could-have-been" aspect, and the sharp contrast between the relatively Lighter And Softer Potterverse and the violent, dystopic Narutoverse. However, most of the more exciting conflict seems to center around Itachi and the Narutoverse side of the crossover, and the conflicts on the Potterverse side are solved with relative ease. Most definitely a Fix Fic. The Boy Who Fell, by Darth Marrs

* Crossover with La Blue Girl
* Synopsis: How do you avoid Oedipus and Age of Consent issues whilst raising a boy whose demonic heritage requires him to feed on sexual energy? If you're Lily Potter, you call on your best friend Emmeline Vance to become a special kind of "wet nurse."
* Warnings: NC-17. Minor squick warnings for naughty tentacles and a few similarly mild fetishes. No underage sex.
* Comments: This has got to be one of the weirdest HP fics I’ve ever read that wasn’t explicitly a Crack Fic, not because it’s a lemon and not because it’s a crossover with La Blue Girl 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 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 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 takes very strongly after James), but I recommend it anyway unless you're fatally allergic to lemons.

* Crossover with Discworld.
* Synopsis: After death, characters arrive in Kings Cross to board the Hogwarts Express, on it's way to "The Other Place". The only trouble is that the train is always delayed because of the leaves on the line.
* Comments: A crossover with Discworld, featuring Death, Albert, and The Death of Rats manning Kings Cross, ushering characters into the afterlife, and waiting patiently with those who are waiting to for someone to catch up.
* User:Comartemis: I... wait... what...? I just cried tears of happiness Manly Tears for Peter Pettigrew and freaking Bellatrix. Either there is something seriously wrong with me or this man deserves a medal for giving the most despicable characters in the series their very own Crowning Moments of Heartwarming.
* Oh gods, I think I just bawled my eyes out due to sheer awesome heartwarming. This is the best story I've seen in a while. A long while. Especially the parts with Bellatrix and Snape and... scratch that. All of it.
* User:Eddie Current did NOT cry over the bit with Kreacher and Reg Black. (sniff) "Did Kreacher do wrong?" No, Kreacher. In this, you were as true as Dobby. DAMNIT ALRIGHT I cried for Kreacher! Awesome fic.
* Death of the Discworld meets the world of Harry Potter always makes an interesting story. My favorite chapter was the one with Severus Snape.
* It warmed the cockles of This Troper's heart, that's for sure.
* Yeah, the less I know about your cockles, the better. Seriously, this was just beautiful.
* If you don't get misty eyed at least twice, one of them during the Kreacher/Regulus chapter, consider it proof that you have been Kissed by a Dementor and have no soul. The Girl Who Loved and its sequel, Violence Inherent in the System, by Darth Drafter.
* Recommended by Chuckg, User:Looney Toons
* Crossover with Sailor Moon and Ranma One Half
* Pairings: Harry/Usagi, Ranma/Shampoo
* Status: "The Girl Who Loved" is complete, "Violence Inherent in the System" is complete.
* Synopsis: Upon receiving some very disturbing news during the summer after his fifth year, Harry does a panicked accidental-magic Apparition straight to China, and falls directly in a Jusenkyo spring... a spring which one Usagi Tsukino had accidentally drowned in the year before. Hilarity Ensues.
* Warnings: Chapter 9 of Violence Inherent In The System contains mild lemon, and some chapters of The Girl Who Loved have off-screen lesbian encounters which get a fair amount of discussion on-screen. Also, the fic starts out with a mention of m-preg. Fortunately, there is no actual m-preg in the story. In fact, the entire point of mentioning it in the first place was to mock the living hell out of the very idea. Cologne's speech on why the entire concept is idiotic made this troper applaud.
* Comments: This started out as a crack fic and then rapidly developed an actual plot, complete with both Crowning Moments of Heartwarming and Awesome. Harry meets and makes friends with Ranma (watching them try to play the "who had the worst childhood/mentor" game with each other was worth the price of admission all by itself), partners up with the ghost of Usagi (whose body is Harry's Jusenkyo-curse form), makes friends with the Chinese Amazons (but avoids the Kiss of Marriage thanks to Ranma's timely warnings), and develops an entire support structure in the form of the Senshi (and Ranma and Shampoo), to the point where by the time he has to return to Hogwarts for his sixth year, Dumbledore and Voldemort both have no idea what's about to hit them. In the meanwhile, Harry and Usagi have fallen in love... which is a bit of an obstacle, given that only one of them is alive, and the other one can only temporarily possess her body when her beloved is morphed into it... fortunately, she gets better. Tackles and answers the tough questions, such as "What happens when you cast a Patronus Charm through the Moon Healing Scepter", "How quickly can Snape's lack of tact earn him a nine-on-one gang beatdown by an enraged mob of magical girls", and "Just what the heck was Dumbledore smoking, to make some of the decisions he did?" Really, it's far, far better than it sounds, and I highly recommend. Also contains perhaps the only non-annoying appearance of Chibi-Usa I can remember seeing anywhere.
* User:Comartemis: Wow. This is probably one of the best examples of Growing the Beard I've ever seen in a fanfic before. The first few chapters are really rough, characterization is spotty at best, several characters are Flanderized to hell and back, Dumbledore, Ron, Ginny, and Molly all get their usual Ron the Death Eater treatment, and while mpreg really doesn't ever show up outside of conversation, the way the subject becomes plot-relevant is absolutely absurd on the face of it. At some point, however -- I think it's right around the same point where the fic turns mildly serious and stops being a Crack Fic -- everything shifts in a generally positive direction. Mamoru is still a complete manwhore, sure, but he doesn't show up more than once or twice before he falls down a plot hole and isn't heard from again. Ginny never really gets better and Molly's attitudes are only weakly justified, but Hermione recovers from her Flanderization, Ron seems to get over his exaggerated jealousy of Harry, and the much-hated Manipulative!Dumbledore actually gets deconstructed later in TGWL. And while Chibi-Usa has never really irritated me like she has other people, I have to agree with Chuckg that she's very well-used here, possibly because her interactions with Harry are infinitely more adorable than her canon relationship with Usagi. It may not hold a candle to some of the other examples on this page but this is definitely one of the best HP/SM crossovers I've ever read. King's Jackal by esama.
* Recommended by Ramenth, User:Seraviel, SelinaCatz
* Crossover with Yu-Gi-Oh.
* Synopsis: "Wrecking all of Dumbledore's plans, the Power The Dark Lord Knows Not walks up to Harry in the summer before his fifth year, and asks for directions." This is the "official" summary for King's Jackal, yet it really does not do it justice. Taking place after Harry's fourth year and some time after the end of Yu-Gi-Oh, the story starts off as what could be your standard Harry Potter crossover. He meets Yami, Yami asks him for directions. Harry follows and eavesdrops, and, well, you'll have to read from there.
* Comments: Despite quite a bit of Out of Character moments, especially on the part of Yu-Gi-Oh! characters, this is one of the best fics that I've read in a long time. It is enjoyable, readable, and full of ideas that I've seen nowhere else. It also has one of the best courtroom scenes that I've seen in years, including on TV. The story does get off to a bit of a rough start, but it picks up quickly and and is an overall amazing read. I strongly recommend it. Also, word to the wise, apparently there's going to be some slash in later chapters, so if that's not your thing, avoid it. I haven't really seen any meaningful hints of it so far though.
* Warning: While I love Esama's writings, she has a limited attention span and tends to stop working on her stories in favour of a new story, so don't start reading any of her incomplete stories if deadfics annoy you. Note however that this fic has not been declared dead (yet) and she has once or twice restarted work on fics she had previously declared dead. Harry Potter and the Invincible Technomage, by Clell65619
* Recommended by Chuckg, User:Looney Toons, User:Unclouded TJ, User:Comartemis
* Crossover with the Marvel Universe.
* Synopsis: A party of executives from Grunnings and their families are given a facilities tour of a factory as part of a joint project with an American firm. When the Dursleys die in an explosion, accidental magic lets Harry be the sole survivor. And when a young child shows visible superpowers on company property, the owner is called in, leading eventually to an 11-year-old Harry Stark attending Hogwarts...
* Comments: The major appeal of this fic is seeing things go right for Harry without him being a God Mode Sue. He has a loving father and virtually the entire Avengers for his extended family. He's self-confident and still heroic (he is in fact 'Pulse', the second auxiliary member of Power Pack alongside his best friend Franklin 'Tattletale' Richards). He has access to Dr. Strange and Agatha Harkness as magic tutors. So why is he still attending Hogwarts? Because Madame Web has told him (and only him) of the prophecy, and, well, a hero has to do what a hero has to do. And so a young Harry Potter whose "saving people thing" is now professional has arrived on-scene. And it was a Crowning Moment of Heartwarming when you realized that the first person Harry helped save was Tony: adopting a small child in 1986 meant that Tony felt compelled to live a slightly more responsible lifestyle, so he never descended into alcoholism, and never lost his company the first time. And the Crowning Moment of Funny when you find out what Tony always does to Harry's school projects... well, read for yourself. Other highlights include Tony forming an informal Hogwarts Parents Association, Harry introducing the student body to (magically-shielded) CD players and cell phones, and Ravenclaw!Harry attempting to design and build the first magical computer.
* Warnings: Do you hate Manipulative!Dumbledore? He's in this one. Its the 'more arrogant and control-freaky than outright evil' incarnation, but still, Dumbles exists in this fic to get verbally smacked down by almost every magical person Tony can call in for support. Culminating in the scene where Thor has to 'explain' to the Wizengamot why overturning Harry's adoption by Tony Stark would be terminally unwise.
* User:Comartemis: Troper hive mind strikes again. Manipulative!Dumbles is an irritation but for a fic this good he's worth dealing with. It's worth noting that this new Harry may have the appearance of a Marty Stu at first (his first encounter with Snape is likely to set off alarm bells but that's a pretty isolated incident) but ultimately proves himself innocent of that label. As mentioned above, this one does a lot of stuff that few other Potter fics do; Harry and Draco becoming Friendly Enemies is one of my personal favorites, along with a new twist on the fiasco with Riddle's diary. An excellent read even if you don't know anything about Iron Man or Marvel Comics in general, but having seen the movies will make the latest chapter even funnier than it already is: Sirius Black meets Robert Downey Jr? HEAD FOR THE HILLS!
* User:Eddie Current: Credit to Clell here -- this version of his pet Manipulative!Dumbledore does come across as more Well-Intentioned Extremist than Complete Monster, but the characterization can still grate a bit. That said, much of the rest of the fic can alternate between bland, grating, and the occasional cool idea that gets lost in the shuffle.
* Ancient Nonun: YMMV, but its bad. So very bad. Flat characters that do nothing but carry the plot, completely unbalanced powers that only exist to show how awesome Marvel is, and everyone else becoming strawmen. The Wizarding World gets the treatment that Sasuke got in Chunin Exam -- unapologetic bashing and exaggeration that leads straight into Character Derailment. Technomage has no drama, no tension, a mine field of plot holes and badly-used clichés, and no depth whatsoever. It's quite possibly the worst fic this troper has ever read. It's the Battlefield Earth of Harry Potter fanfiction. Be warned that even with the honest praises it gets, it can have very unexpected results.
* User:Maki P I've skimmed through 8 chapters, and I have to say that Harry Stark is unbearable. He's arrogant, snotty, conceited, condescending, disrespectful, and just plain annoying; coupled with the aforementioned Manipulative!Dumbledore is impossible to read (Thor chewing the Wizegamot was pretty awesome thought). Also I hate the way he keeps dismissing the Potters, sure he never met them, but they sacrifice their lives for you, you ungrateful little bastard!
* User:The Enmity Of Ages 1994: This fic varies in quality. While the HP characters are either evil, stupid, both (Dumbledore being the main victim of this) or Harry's willing minions, and are all strawmen, the author shows a deft writing touch when they get past their hatred of the Potterverse, with some good scenes with the Marvel characters. The main problem, however, is Harry. He's a Fixer Sue and so OOC it is unbelievable. I was sceptical when it turned out Doctor Strange, the most powerful wizard in the universe, can't get past an accidental magic shield set up by Harry, however this could be explained away with different types of magic etc. However I lost all confidence in it when I saw that Harry was not only a supergenius, but a wielder of chaos magic. The fic is essentially an Author Tract of the most irritating kind, interspersed with good scenes.
* User:Dr Will Hatch 45: This was one of the first fics I ever read, so there's a bit of nostalgia involved, but I really enjoyed this. Yes, it's a Fix Fic, and the author sure as hell exaggerates some of the underlying problems inherent in the Potterverse, but it's well written and Some Anvils Need to Be Dropped. One of the main appeals of this story for me is to show how ridiculous it is for wizards to be hiding from Muggles, and how selfish Harry Potter wizards and witches are. When you have literal gods running around on the streets of New York, government agencies that have no problem employing magic users(S.H.I.E.L.D), and alien invasions every other week, the idea that normal people can't handle a little conjuring starts to become absurd. Most heroes and villains in Marvel have secret identities, but they don't employ mass memory erasure on a massive part of the population like the wizards do just because they don't want to share their gifts with the rest of the world.

* Description: The above sums it up rather well. Q goes to Hogwarts for Sixth Year, and his son becomes the DADA teacher. Just... picture that for a moment. Most of the focus is not on Harry, which should come as no surprise to those familiar with the Entity Known as Q. Has a few cameo appearances by the various crews Q has mess- er, that is, a few of Q's friends show up from time to time. Mutant Storm by Bobmin

* Crossover with the X-Men.
* Pairings: Harry/Ginny, Scott/Jean, Ron/Luna, Neville/Hermione
* Synopsis: After Dumbledore tells him the Prophecy, an angry Harry explodes (figuratively) and discovers he has a strange power, combining intangibility, invisibility and teleportation. Going back to the Dursleys proves to be both a hindrance due to his depression and a chance to practice with his new powers. On the other side of the Atlantic, two powerful telepaths by the name of Charles Xavier and Jean Summers detect the appearance of a very powerful mutant in England... and Charles Xavier realises that he has to come clean on Jean's past.
* Comments: The first thing the wonderful duo did was to tell readers the fanfic was Harry/Ginny. At first, it explores how Harry reacts to his new powers and how this affects the X-Men as Jean Summers discovers that she is Lily Evans' twin sister, adopts her nephew Harry and takes him to the X-Mansion. It then goes forward from that, passing over things such as the revelation of his mutant powers to the Order of the Phoenix, his going back to Hogwarts and how Voldemort plans to include the mutant community in the British Magical War. It includes a believable Manipulative!Dumbledore, Snape working more for Voldemort than Dumbledore (not on his own volition), a great (and funny) Wolverine, and, finally, a good development of a relationship between Harry and Ginny.
* User:Looney Toons: Seconded. It's not great literature and we get a fair amount of Ron-bashing, which is a typical feature of Bobmin's work, but it's still a fun read. Harry Potter and the One Ring of Power by Technomad

* Synopsis: Voldemort tried to obtain the One Ring, but it was intercepted. Now, the Boy who Lived must take over the quest to Mordor, with Hermione Granger, Ron Weasley, and...Draco Malfoy?...as his companions.
* Comments: This may be the first full-length Lord of the Rings/Harry Potter crossover. The author gives us sections from the POVs of Harry himself, Ron, and Hermione. There are also nods to other writers, such as Lois McMaster Bujold, scattered through the text.

* Crossover with The Dresden Files.
* Recommended by Jinx, User:Looney Toons, User:Seraviel, acg452, Jorf
* Synopsis: A seven-year-old Harry finds a blackened silver coin at a low moment in his life.
* Comments: Harry is delightfully snarky and beautifully balanced between good and evil. It also has the best written Dumbledore I've ever read.
* Seconded by User:Looney Toons: And don't miss its sequels The Denarian Knight and The Denarian Lord, and the extras The Denarian Omakes.
* Harry becomes an insufferable Jerkass Mary Sue within the first three chapters, and remains such throughout the next thirty. Despite excellent plotting, quality writing, and an amazingly well-characterized Dumbledore.
* Thirded by acg452: Not necessarily a Mary Sue per se. He is quite powerful, given that he's sharing brain space with a Fallen Angel, but he has his fair share of problems. For instance, getting the coin stolen at least twice, Voldemort blowing up his apartment and pressing Harry's Berserk Button by burning Meciel's silk sheets. And aside from his small circle of friends, namely Meciel, Dumbledore, Amanda, and Amaris, the last of which is his only blood kin, it's pretty clear most people wouldn't mind him just dying off. That said, he doesn't give two shits about them either, so it all works out. Also, the series is now complete! Boo Ya! Alexander Harris and the Shadow Council by Tenhawk
* Recommended by Spooner Wilkins, FrodoLives, User:Looney Toons
* Crossover with The Addams Family and Buffy the Vampire Slayer.
* Synopsis: So far this is a threeway crossover between The Addams Family, Buffy the Vampire Slayer, and Harry Potter. The main focus is on Xander Harris and Wednesday Addams as they they go to Hogwarts but Hermione from the "Golden Trio" does get her share of the story. The story starts of with a slight retelling of the first Harry Potter book and unravels it as Xander works his particular brand of chaos. This could well be described as a day-in-the-life story.
* "Comments": Highly recommend this story. Xander gets adopted (sort of) by the Addams Family. Wednesday terrifies everyone at Hogwarts. Buffy hasn't shown up yet. Harry Potter and the God of Death by Nesarna

When Ed and Al went back to close the gate to their world, the gate drops Ed into Hogwarts. There, he starts working as the Alchemy Professor to find a way home. But, the trio becomes suspicious of Ed...

* Recommended by User:Those Dancing Days
* Crossover with Angel.
* Synopsis: In the summer after Order of the Phoenix, Percy Weasley is is a man without a mission. Recently sacked form his Ministry job after the firing of Fudge, Weasley sets off to find another job. His job hunting takes an unexpected turn when he encounters a vampire, and helps Kingsley Shacklebolt with several missions. With the help of Lorne, Ginny, and Mrs. Longbottom, Percy sets up an "Auror-for-hire" office, hoping to be a "Champion for the Good of Mankind".
* Comments: Incomplete. This story is well worth the read, even though the updates are sporadic (luckily, there's a tag for the story on the author's LJ). Everyone is still in character, plus there's a likable Ginny Weasley! 12 Moves Sideways by Silver Pard

* Crossover with Death Note.
* Synopsis: After the Yotsuba Arc, Light becomes the new Defence Against the Dark Arts teacher. Harry decides he needs watching.
* 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. To Face the Wolf by Maglor's_finch

* Synopsis: Everyone knows what happened when Sirius fell through the veil. What if something different happened to Harry? Harry ends up in Halloweentown where he meets Jack Skellington. Things change forever for Harry and Jack and nothing will ever be the same. Set 7 ½ years after the Christmas fiasco and immediately after the Ministry battle in Harry Potter and The Order of The Phoenix.
* Comments: I have to say, I was not expecting this to be any good (as much as I love crossovers, sadly most Fanfic crossovers are lacking). While some things seem to be Hand Waves or possibly even complete Ass Pulls, depending on how you look at it, the story is quite good, and everything makes sense if you can take some Acceptable Breaks From Canon (like Harry and, according to the author notes, Sirius surviving the fall through the veil).

Takes place during Season 4 of Supernatural and Post-DH for Harry Potter. Vile Violent Vacations is a sequel that takes place during the middle of season 5 of Supernatural.

* Synopsis: It was supposed to be Harry's day off. No such luck for the man that defeated Voldemort 13 years ago. The Borg invade and its up to Harry to save the world, again. But can Real Magic defeat Magic From Technology?
* 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 It Got Worse. And Worse. And Worse. Draco Malfoy and the Snarky Pen Pal by shadowglove

* 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.
* Caution: Early chapters have Harry on the edge of God Mode Sue status, but that gets toned down over time. Also Harry and Clark rarely do any superheroing together, which is kind of disappointing. The Dead of Winter by ForeverFalling86

Mocking shards of memory danced through his dazed mind.The sirens. The cop. The slick road.

* Crossover with Ranma One Half.
* Synopsis: In retrospect, Harry should've known that Umbridge's field trip to the ancient springs of Jusenkyo was an unmitigated disaster waiting to happen. Having fallen into the Springs of the Drowned Emo and Drowned Emu, Harry supposes he's luckier than, say, Snape (Spring of the Drowned Unicorn) or Ginny (Springs of the Drowned Pig and Homing Pigeon), but there are more problems in the upcoming year than just curses that have no known cure: Voldemort takes advantage of his own cursed form to infiltrate Hogwarts as Luna's new pet bunny and actively plots the demise of, well, everyone. And there's really no way to explain Lucius Malfoy, the benevolent Buddhist monk. (AU Harry Potter and The Order of The Phoenix; Ranma 1/2 crossover) Features many minor characters with personalities – especially Daphne Greengrass and Blaise Zabini.
* Comments: Minnionette does a fantastic job of taking an element of one series and fusing it with another near seamlessly. It's a lot like the above Harry Mewter in that only one Ranma 1/2 character shows up and only for one chapter, so no real knowledge of the series is needed. Minnionette has a true gift for character building, and thouroghly explores everyone's personalities and how they would deal with the bizarre situation they find themselves in. And it's all in character, which, to me, means the most. It's also guaranteed to have your sides splitting by the end of the first chapter. Harry Potter and the Colour of Magic by Chardvignon.

After a raid which backfires spectacularly, Senior Auror Kingsley Shacklebolt needs to have Harry re-trained to think like a copper. The only person he can trust? Commander Sir Samuel Vimes, Ankh-Morpork City Watch. Only, magic is a lot more powerful in the Discworld, so Potter had better be careful where he points that thing...

* Crossover with Hellblazer.
* Recommended by Roo, User:Looney Toons
* Synopsis: After interferring in a magical fight (armed with a half-brick in a sock), John Constantine finds himself in another world; a world where magic works differently, demons can't be summoned up, and children go to a magical school called Hogwarts. Luckily, he manages to strike a bargain with Albus Dumbledore, who has the following offer: He'll do everything in his power to help Constantine get back to his own world, if Constantine in the meantime takes the job as Defense against the Dark Arts teacher at Hogwarts.
* Comments: The story was written before Half-Blood Prince, and unfortunately, seems to be a Dead Fic... but the ten chapters that are up are really well done, with many clashes between Constantine and the HP world. Harry himself doesn't show up until chapter ten, but Constantine's attempts at figuring out Hogwarts and his interactions with the Hogwarts staff (and ghosts!) are thoroughly entertaining. Possibly the highlight of the story is the friendship that grows between Hagrid and Constantine -- and Camwyn even gets Hagrid's accent right, a rarity in fanfic. The End of the Beginning by Mariner.
* Crossover with Buffy the Vampire Slayer.

* Comments: Written a little before the release of Harry Potter and The Order of The Phoenix, Mariner puts forth an plausible alternate history and an entirely believable reason why Lily's sacrifice saved her son. Aside from the how, and the introduction of Buffy-verse magical capabilities, doesn't really depart from the establish canon within the books as released to that point -- the fic eloquently provides another history as to how the Potterverse could have gotten to where it is now.

* Synopsis: Watch as Duo chips away at the very foundation of Hogwarts as he breaks down House walls, befriends Gryffs and Slyths alike, mugglfies Malfoys, and flushes cherry bombs down school toilets.
* Comments: This fic is simply too much to adequately summarize without spoiling anything. Duo is completely in-character throughout this whole thing, and it's his character that "mugglefies Malfoys" et al. An alternate summary is "Duo Maxwell's unique brand of luck strikes again. Ron wants to keep him, even if he does have some weird obsession with flirting with Snape. Snape just wants to know where to bury the body." It's just... everyone's in character. The plot makes sense. I'm not really doing it justice, really. Just read it and see what I mean. It also has a sequel, Harry Potter and the Forgotten Heirs.

* Crossover with Torchwood.
* Recommended by Seiryuu, TheEnmityOfAges1994, User:Caellach Tiger Eye, EMY3K, User:Looney Toons
* Synopsis: The Torchwood team have been accepted at Hogwarts School of Witchcraft and Wizardry. Set between "Adam" and "Reset". Rated T because of Jack Harkness, swearing, mature themes, slash etc... it's Torchwood!
* Comments: An amazing piece of work that age-regresses the Torchwood team and sends them to Hogwarts at the beginning of Harry's third year. Story takes place from there onwards and masterfully inserts Torchwood during the years and develops pre-existing minor characters as well as introducing rounded ones.
* Thirded. This is brilliant. The Torchwood characters are cleverly interwoven with the Potter-verse. Fair warning, though, there's a lot of Ron-bashing. -- EMY3K
* I heartily agree. Seriously, I bloody love this fic. It takes all the best elements of Torchwood and integrates them into the Potterverse perfectly without feeling out of place (mostly by adjusting the tone of both series to somewhere in the middle, but without being forced). The characterisation is altogether very strong and consistent, and the bashing of Ron isn't quite as bad as it sounds -- it's more a highlighting of his character flaws compared to the other main HP cast and giving him time to steadily grow out of them (which started when Book Five was reached). It's really at worse Author Tract against Rowling for her own narrative faults (the only thing Ron's being bashed for is fervently hating on Slytherins and nothing else, which as Hermione notes in a later chapter of the fic isn't a good thing). However, it seems that Ron is the only character not to get character development. On a lighter note, there's quite some brilliant humour in there, and some unexpectedly heartwarming moments which are mostly a result of the team's presence. Even better, while the changes do push the story positively (for the most part), the TW team aren't in Fixer Sue territory at all and there's sufficient tension and conflict to go around. This fic is a must-read for TW and HP fans everywhere. Death's Visage by Black-Raven3

* Crossover with Sherlock Holmes.
* Recommended by Logatel, User:Unclouded TJ
* Synopsis: What if, instead of Ron Weasley, Harry Potter met someone else while going to Hogwarts? Would that little detail change just a little detail or would it change everything?
* Comments: The story replaces Ron Weasley (who simply does not exist within the story's context) and replaces him with an eleven year old Sherlock Holmes. It's surprisingly well-done in that it doesn't have Sherlock simply obliterate the series plot and that it doesn't turn into rather frequent logic abuses that some stories take, instead opting to preserve the series' overall atmosphere while changing its pace. It's definitely worth a look if you like both fandoms.
* User:Unclouded TJ: I enjoyed this fic so far and although it would appear at first glance to be cheating you must keep in mind that it's not the adult Sherlock Holmes and he makes mistakes just like any other human. Its main feature is the interaction between Harry and Sherlock and how they seem to work well together. Savior by JoeHundredaire

Main character is an author insert, but it seems to be handled well; Your Mileage May Vary, though, as a few reviewers have noticed some Sue-ish qualities. So far, the main HP characters haven't shown up in earnest; if you don't like OC wizards, don't read this. The fic appears to have died, however. The Wizard in the Shadows by Nimbus Llewelyn
* Recommended by User:The Enmity Of Ages 1994
* Crossover with Lord of the Rings.
* Synopsis: After the Second Wizarding War, Harry goes to rest and recuperate in Middle Earth, 4 years before the War of the Ring. Pity no one told him about the resident Dark Lord. 4 years on Harry goes with the Fellowship, with the chief objective of distracting and fighting Saruman. But when did any of Harry's plans not fall apart?
* Comments: This fic yo-yo's between genres, and after the first chapter (short and mostly to get to Rivendell quickly), it gets longer and better. The Rohirrim gets A Day in the Limelight with numerous sections about what is happening in Rohan, giving us an interesting and well written Theodred. Harry is powerful, having taken a further level or 3 in badass, and enjoys Playing with Fire, and cracks jokes every now and then, but is far from invincible, getting his arse handed to him on several occasions and remains vulnerable both emotionally and physically. The narrating owes more than a little to the Discworld and The Hitchhiker's Guide to the Galaxy in tone, but blended with gentle handling off the quieter scenes. While far from perfect, it is readable, funny and spectacular. Another bonus is the impressive update rate.
