Link and Harry Potter make a Switch
Link must go through school at Hogwartz and face all the things Harry did from year 1 to 7 and eventually fight Voldermort. Link has used magic many times before but this time he must rely completely on it as he won't have the Master Sword. (Still has Triforce of Courage)
Harry Potter has been enabled to use the Master Sword but must first use a crappy sword. He will eventually pull out the Master Sword at the Temple of Time if he survives that long. He must undergo the Ocarina of Time story and will atart at age 11 and then fight the second half of the game as 18 year old with Master sword. (Has magic abilities but no wand)
Ask yourselves important questions:
1. What house will Link go into?
2. Will Harry put up with the fairy?
3. Think outside the box.
(I think they can both fulfil each other's journeys but what unexpected twists would there be?)
