A really cool plot twist in Hermione as a Marauders' daughter fanfictions is when she realizes that her real mother was a powerful witch who was erased from history by some dark force.

Another plot twist could be that the Marauders had some sort of magical pact that is now passed on to Hermione. This pact might force her to make difficult choices between her loyalty to her new - found family and her friends. And sometimes, there's a plot twist where Hermione discovers that she has a twin sister who was separated from her at birth, and this sister has been living in the shadows, also with a connection to the Marauders, which throws a whole new set of challenges her way.
