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.

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.

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.
