One possible plot idea could be two versions of Harry Potter existing simultaneously in Hogwarts, causing chaos as they both try to deal with Voldemort in different ways. Another could be that a spell creates double trouble for Harry, like his magic splitting into two opposing forces that he has to reconcile.
Well, perhaps in this 'double trouble harry potter fanfiction', there could be a situation where Harry's doppelganger is created by a dark wizard. This doppelganger has all of Harry's knowledge but is under the control of the dark side. Harry then has to figure out how to defeat his own double and save the wizarding world. It could involve a lot of internal struggle for Harry as he faces someone who is essentially himself. Also, the double might be used to infiltrate the Order of the Phoenix, causing a lot of mistrust and problems within the group.
In the 'double trouble harry potter fanfiction', it might be about a time - travel related double trouble. Harry somehow travels back in time and meets his younger self.
