Petunia married a biochemist, and Harry grew up reading science and science fiction. Then came the Hogwarts letter, and a world of intriguing new possibilities to exploit. And new friends, like Hermione Granger, and Professor McGonagall, and Professor Quirrell... COMPLETE.

::Year 2 Divergence:: What does it take, to reshape a child? And if reshaped, what then is formed? Down in the Chamber, a choice is made. (Harry's Gryffindor traits were always so much scarier than other peoples'.)

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

Enter the world of Pokémon from a rational perspective. Instead of starting his journey in ignorance, Red has spent his years studying the creatures so central to his world... and he doesn't quite agree with all the information in his books. No time for rookie mistakes here: he's on a quest to discover the true nature of Pokémon, and maybe even find out where they really come from.

AU. Voldemort kills Dumbledore but is defeated by a child. In the aftermath, Snape becomes the Headmaster and radically changes Hogwarts.

Competing with allies and enemies, Harry finds there is a cost to winning.

Mawile just wanted to see the world. If that meant getting shackled to some human, so be it. No one told her that she'd need to fight dragons, deal with world-ending events, and keep her dopey trainer from collecting all sorts of useless team members. Well, at least she had her pokepuffs...

AU inspired by an omake in HPMOR. 12 years ago, the Fourth Hokage gave his life to seal Kyubey, the Nine-Brained Demon Fox, into the infant Naruto. Now, the time has come for a smarter, more creative Naruto to take on a world in which quick thinking and a solid grasp of strategy are worth a dozen rare techniques, and a brilliant mind can challenge even the deepest darkness.

Kyubey promised that humanity would reach the stars one day. The Incubator tactfully refrained from saying too much about what they would find there.

(AU) [Rationality, meet Naruto] - Anko never wanted to lead a genin team. Sadly, the Hokage isn't okay with that; he hands her Naruto, Hinata, and Shino and orders her to "make them the best ninja and, more importantly, the best *people* possible." She's got her work cut out for her. M for combat and occasional cursing.

Alone of every power in Middle-Earth, Saruman innovates, notably gunpowder. But he lost. What if he had a little help? Actually a cross-over between LOTR and the General series by David Drake. Uses both book and movie elements.

Occasional point-of-view chapters/sections featuring Lois Lane. Takes place outside any established comics continuity. Complete. [Content warning: sexual violence, violence, strong language]

When Goku was a child, falling and hitting his head erased his memory and completely changed his life. What would have happened if instead of making him forget, that incident had made him much smarter than he was? Meet a new Goku - who's much more clever, has a taste for philosophy, and a bit of a dark side... A 'rational' Dragon Ball fanfiction, inspired by HPMOR!

In 1991, a child came to Hogwarts School of Witchcraft and Wizardry with obvious gifts, but which few suspected would change the world... Oh, and Harry Potter enrolled that year as well. *** A few tweaks to canon, plus extrapolating Hermione's apparent intelligence realistically. I expect events to diverge fairly quickly. ;) *** cover image cc by-nc RooReynolds @ Flickr

Luminosity is an AU reworking of the Twilight story where Bella is a rational self-knowledge junkie. Inspired by "Harry Potter and the Methods of Rationality". Requires no knowledge of or affection for Twilight canon.

What if the mentioned super intelligence of Yagami Light and his antagonists wasn't just informed, but was actually true?

In a world where modern physics and chakra are seemingly irreconcilable, fifteen-year-old Haruno Sakura graduates as a first-grade genin with the year's highest academic scores and is thrust into a world more complex and a lot less nice than she would have thought at first. AU. Volume one of a planned trilogy. Ch 8, Ignition 1.

Kyle Reese has traveled backwards in time, not to save Sarah Connor, but to help her rewrite the faulty utility function of Skynet. Together, it's possible that they might avert Judgment Day and save the world from nuclear Armageddon - and hopefully create a utopia ruled over by an AI god in the process. Fully completed. Diverges wildly from canon.

A single-/dual-point-of-departure spinoff from Less Wrong's brilliant story "Harry Potter and the Methods of Rationality", branching away in Chapter 81. Hermione is sent to Azkaban, but Harry is not about to give up. Unfortunately, it doesn't look like his enemy is about to leave things alone either.

AU/multiple points of departure, with the intent to fix/sane-itize/create internal consistency, allowing rational agents to take things to the extreme. Visser Three is competent, the Yeerks are moving rapidly, and the Animorphs are actually trying to win (but are inexperienced and unprepared). Inspired by Worm and HPMOR.

There's no such thing as happily ever after. Life goes on - even dearly bought. All Precia's plans may come to nought as shadowy actors take to the stage. But nothing unmasks a man like his use of power. Second of the Gamesverse series.

Six years after her coronation, Elsa rules over Arendelle, using the power of ice to improve the lives of her citizens.
