The art style change could also be used to show the different power levels or the nature of the characters. The more powerful demons from Hazbin Hotel could have a more imposing and detailed art style, with bigger and more complex designs, while the Miraculous Ladybug characters, who are more about heroism and hope, could have a simpler and more accessible art style. This would help to visually distinguish between the two groups in the fanfiction.
If the fanfiction was illustrated, the artist could choose to blend the two styles in different ways. Maybe the background of Hell would be drawn in the detailed and somewhat grotesque style of Hazbin Hotel, while the Miraculous Ladybug characters would retain their smooth lines and bright colors. When they interact, the art style could create a sense of otherworldliness, like two different worlds colliding visually.
One idea could be that the characters from Hazbin Hotel end up in Paris where the Miraculous Ladybug story takes place. They could interact with Ladybug and Chat Noir, and maybe some of the chaotic energy from Hazbin Hotel causes trouble for the heroes as they try to keep the city safe. For example, Angel Dust might accidentally cause a distraction during an akuma attack.
The fanfiction might begin with Queen as an outcast in Paris. Despite her regal appearance, people are afraid of her. One day, she discovers a strange Miraculous - like object. As she touches it, she is filled with a new sense of purpose. Meanwhile, Ladybug and Chat Noir sense a new energy in the city and start to search for the source, which leads them to Queen.
She might become more vulnerable. Pregnancy often brings out a softer side in people, and Lucifer, despite being a powerful figure, would likely be no exception. Her focus would shift from solely ruling Hell to also thinking about the future of her unborn child.
This event in the fanfic could also lead to new characters emerging. Maybe someone would try to take on Ladybug's mantle in a different way. Or new villains could rise, seeing the opportunity in the chaos. The magic of the Miraculous might be affected too. Since Ladybug was an important part of the magical balance, her death could have unforeseen consequences on the powers and the Miraculous themselves.
The social structure in the Miraculous Ladybug world would also be altered. Humans with Kwami might form groups or factions. There could be those who believe Kwami should be used for the greater good only, and others who think they can use their powers freely. This would lead to conflicts and alliances, much like in real - world politics.
Well, if Marinette was a witch, her relationship with Adrien might be more complex. She could be hesitant to get close to him because of the secrets her witch heritage holds. And Adrien, if he had some sort of angelic nature, might initially be a bit aloof towards Marinette as he tries to keep his true self hidden. Their relationship as Ladybug and Chat Noir would also be different. They might have a deeper, more spiritual connection through their Miraculous.
He would probably become more vulnerable. Usually, Angel Dust is portrayed as confident and brash, but pregnancy could make him more cautious as he has to think about the life growing inside him.
It also keeps the interest alive during the wait for new official content. When there's a long gap between new episodes or developments in the official Hazbin Hotel story, these fanfictions give fans something to enjoy. They can explore new storylines and ideas that are inspired by the original but still have their own unique twists, like a fanfic where the characters react to a time - travel scenario.
The akuma might transform Ladybug's outfit into something dark and sinister, or it could turn it into a costume inspired by a different theme altogether.
First, you need to understand the personalities of the characters from both. Bill Cipher is mischievous and chaotic, while the characters in Hazbin Hotel have their own unique traits like Charlie's naivete in her quest for redemption. Start with a simple premise, like Bill arriving in Hell.
