Well, you could create a fanfiction where a character from The Loud House, like Lincoln, makes a deal with the demons in Helluva Boss. He might be desperate to solve a problem in his family, like getting some peace and quiet, and turns to the unorthodox methods of Blitzo's crew. This could lead to all sorts of wacky and dangerous adventures as he tries to fulfill his end of the bargain while also dealing with his family life.
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.
A really interesting concept for a 'helluva boss loud house fanfiction' could be a role - reversal scenario. The demons from Helluva Boss take on the roles and personalities of the Loud House characters and vice versa. So, for example, Stella could be like Lori, all bossy and in charge in the Loud House setting, while Lincoln could be like Moxxie, trying to do the right thing in the chaotic world of Helluva Boss.
One idea could be an OC who is a half - demon, half - angel trying to find their place in the Helluva Boss universe. They could have unique powers that come from both sides of their heritage and face discrimination from both demons and angels.
One idea could be a crossover with Hazbin Hotel. The characters from Helluva Boss could interact with those from Hazbin in the chaotic afterlife setting. For example, Blitzo could try to hire some of the Hazbin characters for a job at I.M.P. Another idea is a crossover with a more mainstream series like Adventure Time. Picture Moxxie and Millie exploring the Land of Ooo and having to deal with its wacky inhabitants while also trying to complete a hit. Or perhaps a crossover with My Little Pony. The contrast between the dark and raunchy world of Helluva Boss and the colorful, friendship - based world of My Little Pony could create some really interesting and comical scenarios.
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 idea could be exploring the backstories of the minor characters in more detail. For example, delving into Moxxie's childhood and how it shaped him into the imp he is today. Another could be a crossover with another similar animated series, like mixing the Helluva Boss universe with Hazbin Hotel and seeing how the characters interact. Maybe a fanfic could focus on Blitzo's relationship with his family and how it affects his work at I.M.P.
Perhaps the story could focus on a hellhound and a human forming an unlikely friendship. They could face challenges together, like dealing with the social stigma in Helluva Boss's world of such an odd pairing. The human could introduce the hellhound to human concepts, and the hellhound could show the human the secrets of the hellish realm.
One idea could be a story where the Loud siblings discover a hidden attic in their house that leads to a magical world. Another could be a fanfiction focusing on Lincoln's adventures in a parallel universe where he has different superpowers. Maybe a story about the sisters teaming up to start their own band.
One idea could be a crossover where the Loud family members gain ninja abilities. For example, Lincoln could be a skilled shadow clone user like Naruto. Another could be that the Naruto characters end up in the Loud House world and have to adapt to the strange family dynamics there. Maybe Naruto tries to teach the Loud siblings some of his ninja values like perseverance.
One idea could be a crossover where Naruto characters end up in the Loud House world. For example, Naruto and his friends could attend the Loud siblings' school and get involved in their daily shenanigans like dealing with bullies or school competitions. Another idea is a story where the Loud House kids discover ninja powers similar to those in Naruto. They could start training and use these powers to solve problems in their town.
One idea could be exploring a different timeline where the Loud siblings have different careers from a young age. For example, Lincoln could be a successful young artist. Another idea is to focus on a mystery within the Loud house, like a hidden room with a family secret. Or you could do a fanfiction where the family goes on an adventure to a magical world that only they can access.
One interesting concept could be how a human character adapts to the chaotic and demonic world of Helluva Boss. Maybe they have to learn new rules, deal with different species, and face moral dilemmas that are unique to that setting.
