Pain is the Passaic of the Soul -- Pain adopts Naruto in amekagure
Sealed With a Quiche -- Harry Potter's accidental magic manifests early, when he ruins a quiche, making him a master chef who is in much better (and fatter) Dursely situation... translates over to potions... 'What inside me is the ingredient that kills Dark Lords!'
Premonitions of a Civil War -- Lelouch gets to Japan earlier and has a much better power base when he gets the geass
Soft Construction in Baked Beans -- skyrim fic, author insertion involving a mangled dragon language translation which means "soft construction in baked beans" which somehow transmutes monsters into pork & beans
Dionysius and the 'Shrooms -- Kodachi has a drug trip and ends up on the far side of sane... she proceeds to change everything (R.5)
