A cool Helluva Boss crossover fanfiction idea could be with the world of Gravity Falls. The I.M.P. crew could end up in Gravity Falls and get involved with the mysteries there. Blitzo might mistake Bill Cipher for some powerful demon from their own world and try to make a deal with him. Also, a crossover with Rick and Morty would be wild. The high - concept sci - fi adventures of Rick and Morty combined with the Helluva Boss's dark humor and demon - centric world would lead to some insane storylines. For instance, Rick could accidentally open a portal to Helluva Boss's Hell and they all have to deal with the consequences.
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.
Well, a crossover with Steven Universe could be really unique. The demons from Helluva Boss could visit Beach City and cause all sorts of chaos. Maybe they'd be intrigued by the Gems and their powers. Another interesting one would be a crossover with The Owl House. Luz could find herself in the world of Helluva Boss and try to bring some of her positive energy and friendship - building skills to the demons there. It could be a story about how she tries to reform some of the more unruly demons while also learning about their world.
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 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.
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 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.
One plot idea could be Fizz and Ozzie facing a challenge in their relationship due to external pressures in the Helluva Boss world. Maybe there are other demons who don't approve of their relationship and try to break them apart.
One idea could be a crossover with 'Toy Story'. The Boss Baby could end up in the world of toys and have to deal with Woody and Buzz. Maybe he tries to take over the toy hierarchy, thinking he can run things better. Another could be a crossover with 'The Incredibles'. The Boss Baby might try to recruit the Incredibles for some top - secret baby - related mission. He could use their superpowers to achieve his goals.
Maybe a crossover with a post - apocalyptic world. Big Boss enters a world like that of The Walking Dead. He has to use his survival and combat skills in a completely different scenario. He could form an alliance with some of the survivors there, teaching them his ways of combat and in return, learning about their unique ways of surviving in a world full of zombies. It would be a great mix of two different universes.
A plotline might involve them going on adventures together outside of their usual work - related tasks. They could discover new aspects of each other's personalities and grow closer as a result. Also, there could be a plotline where they face opposition from other characters in the Helluva Boss universe who don't approve of their relationship.
Well, a lot of Helluva Boss fanfiction focuses on redemption arcs. Some characters in the show have morally grey areas, and fanfic writers often explore the idea of them seeking redemption. For instance, characters like Stolas might be written to have a more in - depth journey towards making amends for their actions. And then there's the theme of power struggles. Given the hierarchical nature of Hell in the show, fanfics can delve into how different characters vie for more power or try to maintain the power they already have.
