Fanfictions I Recommend:

Sorry no links, you'll have to type the titles or authors into the search if you want to read these.

Please note: I read both het and slash so you'll find stories of both nature here. And a number of stories (especially oneshots or short, usually pre-canon-events stories) that don't have a pairing, focusing on other things. I've also bolded the authors who write more than just one or two stories I particularly enjoy.

Disobediencewriter: author has tons of fics and I recommend most of them, so I won't list them all here and you can look up the author instead! Harry Potter fics.

kirallie: Ditto above! HP, Naruto, and HPNaruto fics.

padawan lynne: Mistress of HP Star Wars crossovers; "Walking a New Path" multi-fic epic. Harry trained by Windu, later training Anakin. Also "The Chronicles" series which introduces an OC Jedi mentor, but that one is currently taken down for rewrites (we seem to have the originals back up for the moment, no telling if they'll stay). Looks like a fair amount of fics in the works too, and most of them are HPSW crosses.

"Aftermath: A Story of Blended Cliches" by trimatter - A Ranma fanfic crossover with Sailor Moon and Tenchi Muyo. A Ranma-chan fuku-fic, but an extremely good one, pairs Ranma with Tenchi. The only thing I found weird was the beginning and ending - the beginning is a prologue of post-fic events before the majority of the fic becomes a sort-of flashback, but then the ending goes over the events of the prologue differently. I overlook those small continuity errors because the majority of the fic is absolutely awesome!

Ar-Kaos has a multi-fic Ranma epic starting with "Dead Man Walking" and ending with Arc V "Gateway To Dawn". - This is a Ranma-Nabiki pairing featuring an older, smarter, tougher Ranma, darkish military themes, and evil aliens (though the general populous don't know about the aliens). Truly fantastic with well-developed characters and a believable but still insane Kodachi and a psychic Gosunkugi Hikaru.

"Blood Prince"; "Heir of Blood"; "Blood's Sacrifice"; "Blood Dance" by Shade Dancer - A Mafia!Harry Potter series with realistic OCs and new sides to canon characters. Shade Dancer finally returns to the series for the fourth installment. The series seems to be following a one-fic-per-Hogwarts-year routine. This is a Harry-femBlaise pairing, and the story is great!

"A Second Chance at Life" followed by "Changes In a Time of War" followed by "A Magical World" by Miranda Flairgold - Trilogy: Harry becomes independant and leaves for a new, tough and awesome school in Canada and makes new friends. Voldemort's just the beginning. Now there are demons invading! Vampires, fae, elves, bloodmagic, and more!

The Elemental Series (four fics) by Raven Dragonclaw - Harry gets amnesia, is adopted, and joins a society of elementals even more secret than the Wizarding World. Plus the gods are real and love to meddle, and Dark Angels are being reborn. The series seems to have been abandoned unfortunately, it hasn't updated in quite a while. But that's no reason not to read what has been written, because what's there is awesome!

"Hero of the Thousand Retreating Backs: Harry Potter" by Chibi-Reaper - A Harry Potter Discworld sort-of crossover. Features a cowardly Harry and his best friend DEATH. Awesome and funny!

"Just Another Perfect Soldier" by sparkley-tangerine - Harry Potter Gundam Wing crossover. Harry and Heero, very much alike and possibly upcoming slash pairing. The Gboys have a new bodyguard duty, and where has this new mysterious gundam come from?

"Orion Black: Time Traveler" by Rose-Aislin - Harry Potter is missing and then Sirius Black's husband, a Hunter and a time traveler, turns up. But where's Harry? (Rose-Aislin also has a related fic that gives a series of oneshots of Orion's time with Sirius back in the Marauder's Era)

"Partially Kissed Hero" by Perfect Lionheart - a great super!Harry, pairing with Hermione and Luna. A partial Dementor's Kiss in third year unlocks the horcrux in Harry and he begins to fight the Dark Lord Voldemort and the Dark Lord Dumbledore. Kentucky Fried Chicken - finger lickin' good!

"Perfectly Abnormal" by evansentranced - oneshot, pre-Hogwarts; Harry is perfectly abnormal thank you, and driving the Dursleys insane passive-aggressive style!

"Fighting the Gods" by phoenix catcher - HP SG1, Harry the Tok'ra, last of the Alterrans. But who is Ryver Potter?

"Cast Between Worlds" by phoenix catcher - HP SGA, Harry loses his magic but gains a new power. Joins the military and eventually the Stargate Atlantis team. eventual slash.

"Harry Potter and The Ancient's Bane" by Kalistar - HP SGA sibling-who-lived, Harry is John Sheppard's younger brother.

"The Immortal Spacemonkey" by Shannon K - SG-1/Highlander crossover fic: Daniel is Immortal and there are people after his head, even on other worlds! I think there's a sequel now too.

"Take the Green and Go" by Usagi-Hasano - Ranma falls in Spring of Drowned Shego. Crossover with Kim Possible.

"Silver Moon, Golden Sands" by Scarlet Moon - Sailor Moon Yugioh crossover with YamiSerenity pairing, Mamoru and majority of senshi bashing.

"What Dread Hand" by Bone White Butterfly - a Batman Beyond fic; Terry goes deep undercover with the cat-people. Then things start to go wrong. Chapters are not entirely chronological but later chapters include a timeline. Very well written.

"Sudden Burst of Speed" by CRose - Ranma gains the Speed Force and joins the Flash family over in the Marvel Comics superheroes world.

"Harry Potter and the Invincible TechnoMage" by Clell65619 - Harry is adopted by Tony Stark (Ironman). Super-tech and chaos magic! Befriends Hermione and the Patil twins. Still too early to determine pairings, but I can make an educated guess. grins

"Technomagus" by esama - HP SG1 crossover. Harry with an Ancient Repository of Knowledge in his head, the Flamels as his guardians, and is using Alterran tech to change the muggle and magical worlds.

"The Awakening of a Magus" by the-dreamer4 - super!Harry but very well done. 5th year Harry becomes a magus (mage). One of the best super!Harry fics I've read. Severus Snape and Draco Malfoy are good. Best "super Harry" fic!

"The Best of Times" by Ozzallos - Ranma vs Sailor Pluto, Ranma in a fuku, and two alternate endings.

"The Essence of His Soul" by My Echoing Silence - Harry and Kuronue share a body. sibling-who-lived fic with a yuyuhakusho twist!

"The Tiger Who Knew Too Much" by Lily of Trust - a Ronin Warriors story. No armors, but plenty of mafia. Sorta Dick Tracy-ish; Mia is a PI! Sage returns from the dead! Very intense.

"The Truth in All Things" by P.L.S. - HP HL BtVS SG1; Methos was Slytherin and Harry used to be an Immortal. Giles and the Watchers, plus Immortals going through the Stargate. The Hogwarts Founders were not who you think!

"The Ultimate Escape Artist" by dogbertcarroll - Harry Potter, ultimate escape artist. pre-Hogwarts. It's hilarious!

"Crucible" and "Wall of the World" by sexylyon - two unrelated but excellent Gatchaman fics. Very introspective.

"Not Your Usual Veela Mate" by Janara - veela!Draco and mate!Harry, but note the title. It's actually quite interesting and develops Harry and Draco's relationship slowly and well.

"Desperate Measures" and "Raspberry Jam" by v v c - two more, unrelated, DracoHarry fics that develop their relationship well and in new and interesting ways. DM features independent!Harry as a veela. RJ is a bonding fic with no veelas.

"Invisible Sun" by lightning bird - a Fusion Fall fic, mildly AU, of pre-game events. Dexter meets the PowerPuff Girls and finds friendship and family. Leads into a during-game fic "Taken", and sequel "A Time For Heroes" set between the two. ATFH focuses on Ben-10 and Dexter's developing friendship as the FusionFall war kicks off. Quite well written.

"In Another Lifetime" by Jade Hunter - Ranma encounters the Sailor Senshi. Things don't go as the girls expect. oneshot. Unique take on the Ranma-from-the-Silver-Millenium plot.

"Make A Wish" and sequel "The Hunt For Harry Potter" by Rorschach's Blot - Harry Potter is in desperate need of a vacation before the inevitable face-off with Voldemort. Thanks to a series of oddly omniscient shopkeepers, he gets a very interesting one. And the world learns to respect - and fear - the enigmatic Mr. Black, who may or may not be Death Himself... See also "Back In Black" for series of oneshots set in fic's universe. My favorite "Harry leaves" fic!

"Summer of Independence" and sequel "Year of Changes" by redfrog - Independent!Harry learns Dumbles is keeping the Potter inheritance from him, and goes off to a Quidditch Camp he owns. Features Quidditch, broom-making skills, Dumbles and Ron bashing, and a Seeker show-down with Victor Krum!

"RuneMaster" by Tigerman - Harry drops Divination and switches to Runes, and discovers he's a prodigy! Hermione's jealous, goblins are falling over themselves to help him, and Death Eaters are meeting the Grim Reaper.

"Poison Pen" by GenkaiFan - Harry is tired of the press being so fickle, and starts writing under the penname Oliver Twist for The Quibbler. There's also a similar fic "Celestial Requiem" by Raven Dragonclaw (yes, the Elemental series author) where he writes for both Muggle and Wizarding papers under a penname. Both fics serve to bring up the "where's the common sense?" issue in interesting ways. "Poison Pen" is less cynical and somewhat more humorous in my opinion.

"Realizations" by Wishweaver - Harry returns to Privet Drive after 4th Year only to find it empty! Heading to the Leaky Cauldron, he finds himself doing oddjobs around the Alley under the name "Sparky" and meets a muggle family with two young muggleborn daughters, who just may be a new family. Excellent fic!

"Who's Afraid of the Dentists' Daughter?" by TardisIsTheOnlyWayToTravel - Hermione (alone of the Golden Trio) is Sorted into Slytherin, where she is promptly mistaken for the Dark Lord's daughter. So far the only great Dark Lady Hermione story I have read, as they are rather hard to find (though I wish I could find that other one where Bellatrix goes to kill her parents and is forced into a dental exam, only to pledge herself to the two muggle dentists for their ability to make muggles pay for their own teeth torture - it was hilarious but I can't remember the title!).

"Harry Potter and the Attack of the Clones" by Merkwurdigeliebe - One of my favorite HP/SW crossovers. Harry is flung into a galaxy far far away and trained by Yoda, and Syfo Dias appears to make a return. Possible Harry/Padme Amidala pairing.

I have other fics in my favorites list, but the ones above are the best of the best!
