Ouroboros (Harry Potter)

(Dropped) A guy finds himself in Harry Potter, but it isn't quite the world he remembers from the books. Girl-who-lived? Living parents? Non-fugly Voldemort? Even with more retries than Bill Murray and Tom Cruise combined, can he figure out the perfect run?
Edit: I intended for this story to be 80% action and 20% comedy. Instead, it's 20% action, 30% angst, 5% comedy and 45% plot holes.
