The concept of the 'do-over' is used in, at the very least, hundreds of Harry Potter stories. Here's my own take, using a HP character that actually has a good reason for getting another chance to make things better.

YAHP/GHF. Harry is repeating the worst day of his life over and over again. Department Of Mysteries Day.

AU: DSM Revan/Bastila: What he has feared for years is finally coming to pass, the True Sith have begun their crossing into the known Galaxy. It will take every bit of Revan's strength to fight them and all through it, Darkness will permeate uncontrolled

Harry dies after living to an old age. He finds himself in his 11 year old body again. What's going on? Death tells him to fix things. Time Travel HP!Multi HP/HG/NT Finally posted chapter 10. Thanks every one.

Massive multiverse crossover between Harry Potter/Buffy/Stargate/Star Trek Enterprise/X-Men/Fantastic Four/Iron Man/Highlander/Justice League/Underworld/Star Wars and More in that order. Harry Potter is the main character. Full summary inside. Non-Traditional-Harem, Builds up to Awesome Power Harry. 1 Million Words. 150 Smut Scenes (Very Sensual Story).

CURRENTLY ON HOLD PENDING REWRITE. No estimation of when that'll happen though. Sorry.

Harry decides to buck up and start getting ready for what ever Voldemort might throw at him. in the process he finds out the potters are descended of Merlin himself. What will our wayward Hero do with his new found Inheritance

Seven year old Harry dreams about a girl with Silvery Gray eyes. Through an act of violence Harry ultimately finds the true meaning of family.

Who is Harry Potter? A son, a brother, a good guy? No. A nephew, a friend, a hero ? Somewhat. Destined for greatness? Yes. A prick? Oh, absolutely. (Updated less often than once per month. Read at own risk. Author already aware of the problems of first year(s). Questions in disclaimers and ANs of chapters 1-40 do not need to be answered anymore.)

Harry dies killing Voldemort,and is given the chance to go to a world where his parents are still alive.See how he handles all that life throws at him.HaremSisterIncest Powerful/Harry NevilleBWL

Instead of watching, Black talks to Harry before the Knight Bus arrives. This simple and seemingly small decision opens new doors for Harry, giving him more spells, new abilities, and a new outlook on people in general.

This is my take on the fourth year and what should have happened in an ideal Harry world to reward him for his shitty life. Give it a look and tell me what you think. HP/AJ/AS/KB

After having watched his best friend killed in front of him by people he thought was family, followed shortly by another tragedy in his life, Harry sets out to find a way to change his past. AU End/Post OotP, H/Hr/Multi Full Summary Inside

A Dragon, Magical Girls, Martial Artists, the JSDF, the US Navy, the US Army, the Dark Kingdom, and even a few 'normal' people. Tokyo has an eclectic population, and War comes. Ranma/Sailor Moon/Full Metal Panic/Others crossover. No pairings, fixed format

After Halloween, it turns out nobody's costume left anything significant over. However, that doesn't mean they didn't wish it had. Also, in the backlash of all of that chaos magic, that doesn't mean there wasn't magic to be found.

Xander dressed as Doc Brown out of Back To The Future and invented a time machine. PTB got tired of him going back to wear costume after costume and kicked him out, beginning a Slider adventure. First stop? Halloween in a canon Buffy-verse.

YAHF but why should all the costumes be American when the proprietor isn't? Xander dresses as the last human alive...

Go back to the beginning, that was the plan. Stop Voldemort on the cusp of becoming a dark lord, stop him before he created his first horcrux and change history before it could be written. That was the plan, only Harry made a mistake. HIATUS

My try at a 'not the BWL story'. Darren was a hero, Harry appeared a squib. Darren went into hiding, harry ended up dying. Watch as in his place something worse than Riddle gets the chance to run rampant. Rejoice, for very bad things are about to happen.

YAHF! The Scoobies dress as popular comic book characters, but popular characters are always subject to personal interpretations...

Natives that can't decide whether to like you or not? Okay. Survival in a new environment? Alright. Adapting to a new form? No problem. Blending into a new culture? ...maybe not so much. Rated T for language.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it?

You know those times where you look at a game and say to yourself "If it was me in there, I would do it better"? Don't do that, that is what we call 'tempting Fate', and it will never end well.

Alex has been thrown around fictional realities for almost 60 years without aging or control. This time, he jumped to Ponyville, and will be staying for a lifetime. Can he build a life here? Does he want to? What about the family he left behind?

The unlikeliest of crossings. The most improbable of incidents. The most hilarious of universes. A considerably different sort of crossover. Sanity is for the weak anyway.
