In some fanfictions, Harry's time - mastery allows him to interact with past versions of himself. This can create really complex and mind - bending scenarios. He could use these interactions to gain wisdom from his past experiences more directly, or to give his past self crucial information that would help him in his battles against Voldemort. For instance, he might tell his younger self about a hidden weakness of a particular Death Eater that he discovers in the future.
A great plotline in such fanfiction could be a Potion Master being framed for creating a harmful potion.

They might have to enlist the help of their students or former colleagues to clear their name.

In some fanfictions, Harry's mastery of illusions might lead to him being able to enter people's dreams and manipulate them.
