One idea could be to have the characters from Helluva Boss somehow end up in the world of The Loud House. Maybe Blitzo and his crew are on a mission and accidentally cross dimensions. Another idea is a crossover where the Loud siblings get involved in the chaotic business of I.M.P. from Helluva Boss.
Starting a 'helluva boss loud house fanfiction' can be exciting. You should start with a simple idea, like a character from one show being curious about the other show's world. For instance, Loona from Helluva Boss might be intrigued by the large family dynamics in The Loud House. Then, build on that idea. Develop the characters' reactions and how they adapt to the new environment. You can also start by writing a short scene that sets the tone, like a demon from Helluva Boss popping up in the middle of a Loud House family dinner. This can immediately introduce the concept of the crossover and draw the reader in.
One common theme is family. Since the show is centered around the Loud family, fanfictions often explore different family dynamics. For example, how the siblings react to Lincoln's supposed 'bad luck' in different ways than in the original episode.
One interesting 'Loud House No Such Luck' fanfic could be one that explores Lincoln's feelings in more depth. Maybe it shows his inner thoughts during the events of the episode that we didn't get to see in the show. Another could be a fanfic that changes the outcome of the episode, like having his family realize they were wrong to be so superstitious about him.
One possible fanfiction could be that Lincoln constantly has bad luck in his attempts to get some alone time in the house. For example, every time he plans to have a quiet reading session in his favorite corner, one of his sisters accidentally spills something on him or makes a lot of noise right there. It could also be that his bad luck extends to school, where he always seems to be the one picked on by the teacher for things that are not his fault, like when his classmates play pranks and he gets blamed in the Loud House Lincoln - bad luck scenario.
Perhaps a fanfiction could explore a different dimension where Lincoln's bad luck actually turns out to be a superpower in disguise. He could start to use it to his advantage and save the day in unexpected ways.
Well, in 'the loud house no such luck fanfic', the fan - created settings can be really engaging. Maybe the author decides to set some scenes in places that we don't often see in the original show, adding a fresh perspective. Also, the dialogue in the fanfic can be quite different.

For instance, the conversations between Lincoln and his friends about his so - called bad luck could be filled with more humor or more serious advice than in the show.
