I have an idea for a loud house horror story involving my OC idea named Lomond Loud. Lomond is a killer mutant loud sibling with superpowers. In this story, Lomond and Lincoln are working together to kill all of the loud sisters except for Lily as revenge for the events of the episode "No Such Luck". No Such Luck is one of the most hated episodes of the Loud House and as a result of that, tons of "No Such Luck AU" fanfics have been written. In my AU of No Such Luck, my OC Lomond and Lincoln are getting revenge by killing all of the loud sisters except for Lily like mentioned earlier. Do you think the loud sisters would deserve this? What advice do you have for writing this story?
