From the Shadows by Hostiel reviews
Many prophecies had been spoken about the six year-old Harry Potter, but one fact was common in every foretold future: the boy would be great. Ra's al Ghul knew this, but he also knew that under his mentorship, the boy could grow to be the greatest. He would train him in the ways of mortal and magic alike, and the world wouldn't know what hit them until it was already too late.

Why Cats? by Bekatfela reviews
Potter luck was both a blessing and a curse. It was like Sod's Law in action: if something could go wrong, it did, and usually in the worst possible way. He'd never even dreamed of being stuck in a Zombie Apocalypse though. AU, OC's. Not a one shot. Slow updates.

Phoenix by Mcdawn reviews
Harry wasn't one to look a gift horse in the mouth, so when the Dursleys said they were going to Hawaii and he was coming with them he was very excited despite the knowledge that he would probably spend a lot of his time being kicked, punched, being invisible and most likely carrying the bags.
