What fandom has the worst fanfic? Or what fanfic specifically did you read that stuck with you?

If ya'll have any funny summaries of any you read please include that

My take? Voltron (lol it was very long ago and I was curious at the time, but I couldn't find a single good one) and Hannibal (loved the series, was curious what people could come up with and not a single fanfic was good. Writing was phenomenal though).

I'm ready to have my mind changed though.
