A question for the authors of fanfiction novels what is the weirdest thing you have written?

For me, I made Chung Myung from the manhwa The Return of Mount Hua Sect have a child and she is the heroine of the novel, but in the original work he doesn't like women ┏(＾0＾)┛ And I did a lot of things in different ways, like making Michelle Kaiser a father at 19.
