One great place to start looking for Helluva Boss Josh x Ace fanfiction is on Archive of Our Own (AO3). There are many stories there with different plotlines. Some might focus on their adventures together in the Helluva Boss universe, while others could explore a more romantic side of their relationship. It really depends on what kind of story you're into.
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.
Some of the antagonists from Helluva Boss could also be important characters in the fanfiction. They could try to disrupt the relationship between the hellhound and the human. Maybe a powerful demon who doesn't like the idea of a hellhound getting involved with a human and tries to stop them, creating a lot of conflict and action in the story.
The storylines in Hazbin Hotel might not be directly affected at first. But if the characters start to get influenced by the ideas in the Helluva Boss fanfiction, it could lead to some changes. For example, a character might get inspired by a character's behavior in the fanfiction and start to act differently in Hazbin Hotel.
Well, the reactions could vary greatly. Some characters might find the fanfiction hilarious and enjoy seeing different takes on the Helluva Boss world. Others could be offended if the fanfiction goes against their moral code or the general theme of their own show. It really depends on the nature of the fanfiction and the personalities of the Hazbin Hotel characters.
The 'A Night with Loona Helluva Boss' comic is full of surprises and twists. It has a unique story line that takes Loona on a journey through a mysterious and sometimes chaotic night. The illustrations are detailed and really bring the characters to life.
First, get to know the characters well. Watch the Helluva Boss episodes carefully to understand Josh and Ace's personalities, their likes and dislikes. Then, think of an interesting plot. It could be something like a mystery they have to solve together. Start with a strong opening that grabs the reader's attention, like a sudden danger that they face right away.
Another theme is the contrast between their personalities. Moxxie is more reserved and proper while Loona is brash and moody. Fanfics play with this difference, showing how they either clash because of it or find a way to complement each other. For example, in some fanfics, Moxxie's calmness helps soothe Loona's temper, and Loona's boldness encourages Moxxie to be more adventurous.
