What if Sirius Black had been more cautious approaching Harry before 3rd year? How might Harry's life have changed for that one simple divergence in his path? A reimagining of A Witch, A Wizard And A Mechanic. Starts out fairly different but expect similarities. Rated T to start. Additional warnings in first author's note.

I have a singularly impressive talent for messing up the plans of very powerful people - both good and evil. Somehow, I'm always just in the right place at exactly the wrong time. What can I say? It's a gift.

Taylor gains powers in the locker; this much is familiar. But the power she gets, and what she does with it, begins to change things around considerably. Faced with the pressure of the power she has, and official apathy, she must make her own decisions, and take a different route to achieve her goals. There will be trouble.

Naruto botches his first attempt to summon and ends up in a land without Ninja. Now a bunch of monks called Jedi think he's up to no good, the only way home may require the Darkside aka the Fox, and home may no longer be there.

It began with a quirk of timing. It continued because dragons, such as what 8-year-old Harry Potter just turned into, are large and difficult to control. Fortunate for everyone he's a nice kid, eh? Shadowrun and Rifts crossover. You have now been warned.

I never pretended to know what I was doing in my last life. Why should I pretend to know anything about this one? Well, the other option is a horrific and bloody death, so...I better start learning how to be a witch. OC Self-Insert/Draco's Younger Sister. [DEAD]

On Hiatus due to Real Life and I'm sorry so deeply sorry for the broken promise

As Red X he builds a new reputation and battles against enemies both new and familiar. Ch17: Red X fights against Klarion and is placed under a spell, making his worst nightmare a reality.

This story, as a few are in the world of Harry Potter fanfiction, stems from one of those many ideas of Rorschachs Blot, entitled "Nothing to Lose." One of the areas this story will explore is the possible impact on Harry Potter and friends of the isolation that our dear old friend, Albus Dumbledore, always fed to him: this isolation will make up its own reality.

The "power" the Dark Lord knows not is a mentally ill vigilante from another universe trapped in the body of an eleven year old witch.

Albus Dumbledore gets an unexpected visitor in his office one late summer night. The Headmaster finds himself talking to a monster he never knew could arise from his actions. Darkish.

A continuation of "A Dreary Man in a Tedious Job"(which you should read before you read this story). What would happen to Picard if Q did not send him back to his own reality in TAPESTRY.

Yet between his own heart and the Fourth's intelligence, it seems that won't be as easy as he'd hoped.

"Bruce, tell me again why this arm is so important." "Because it came from another dimension." A desperate move by Kakashi sends the rookies into another dimension, revealing a world crisis for both the Justice League and the Teen Titans. BONUS CHAPTER UP

Sakura thought she was a capable kunoichi until she died in the Chuunin Exam. Now she's stuck in a loop, dying again and again while she struggles to understand her strange predicament. How hard can it be to pass one stupid test? Sakura/Naruto/Hinata

AU time travel: The kyuubi no kitsune knew something was wrong, but couldn't put a paw on quite what. However, there are benefits to being a force of nature, including time itself bending to accommodate you. Edited version on AO3!

In the station between Life and Death Harry makes a different choice. Now he is eleven again, nothing is going the same as before, and people are starting to ask questions, especially the Malfoys, the Hogwarts professors and, most worryingly, Mad-Eye Moody. Harry is beginning to suspect that he might not be up to this Master of Death business and everything that goes along with it.

Harry Potter won the Second Blood War and defeated his enemies... and was left with nothing. Decades later, he contributes to the creation of a revolutionary new piece of technology and destroys the future in order to rewrite his own past...

Ever wonder 'Why don't they just do that' "A lot of the greatest wizards haven't got an ounce of logic." Harry and Hermione, however, were raised in the muggle world and are therefore fully capable of thinking things through...A collection of of one-shots

A banished Naruto is told he needs to return to the Hidden Leaf by an emissary of the new Rokudaime Hokage. His reaction isn't what you'd expect.

Harry was sent to Azkaban after being framed for murder in the beginning of his 6th year at Hogwarts. While there, he unlocks the "Power the Dark Lord Knows Not". What will happen once his former friends know he's innocent? Watch the fun.

The price of freedom always comes at a cost, including to those left behind to pick up the pieces. What if some of those left behind weren't as loyal as they appeared, would they reap what they have sown or get off scott free?

My name is Naruto and I'm cursed. I'm trapped in a loop of time, reliving the final fourteen years of my life for the third time. Only this time things will be different, because this time I have a plan to escape. Rated T for language & so on.

Harry Potter has just received his Hogwarts letter, but really doesn’t want to go. After all, who would want to live on a planet? Especially one where the natives think nuclear energy is high science. And let’s not forget the 42,000 lightyear commute.

COMPLETE. Two years after defeating Voldemort, Harry falls into an alternate dimension with his godfather. Together, they embark on a new life filled with drunken debauchery, thievery, and generally antagonizing all their old family, friends, and enemies.

Nuclear war breaks out and Voldemort casts a spell to stop time. He and Harry alone are left to defuse the missiles and prevent the war. Voldemort’s radiophobic. Oh joy. LVHP. Spoilers for HBP, none for DH.

Hired to steal a supposed alien from one of Paquin's top ringmasters, Mal Reynolds figures things are gonna go even less smooth than usual. Then a passenger calling himself 'the Doctor' shows up, and things go all manner of crazy...

My take on Harry's first year starting with him getting his letters. Add a lot of sarcasm, stir, and serve cold.

The war is over. Voldemort won. The light's last hope is a desperate ploy, concocted by an insane genius, that probably won't work anyway. Now Harry must find a way to win a war he's already lost once before.
