It could be a jealous artist named Max. Max has always been overshadowed by Bendy and Betsy's talent. So, he devises a plan to steal their ideas and take over the art world in their story. He starts spreading rumors about Bendy and Betsy to turn other artists against them.
One idea could be that Bendy and Betsy start off as rivals in an art competition within their strange world. They both have very different styles, Bendy with his more cartoonish, edgy style and Betsy with her elegant and refined art. As they compete, they gradually learn from each other and end up collaborating on a masterpiece that combines both of their unique talents.
Well, the two main characters are Bendy and Monika. Bendy, a character full of mystery and a touch of horror, brings his unique aesthetic from his dark, ink - based world. Monika, a digital entity with her own emotions and motives, adds a different kind of depth. In the fanfic, they are the ones who drive the story forward. Their interactions, whether it's a clash of their different natures or a coming - together in understanding, are what make up the heart of the story.
Perhaps in the fanfic, both Bendy and Monika are pulled into a neutral void - like space. At first, they are both on guard. But as they start to communicate, they realize they have a shared sense of loneliness. Monika has been alone in her game world in a way, and Bendy has his own isolation in the ink world. They then decide to explore this new space together, finding strange artifacts and entities. As they journey, they grow closer and start to understand that their differences can be a strength, and they work towards a goal of understanding the nature of this strange space they are in.
Maybe there's a new character, a mad scientist who has been observing both the Sonic and Bendy universes. He creates a device that can merge the two worlds in a chaotic way, causing disasters in both. He believes that by doing this, he can become the ruler of the combined universe. Bendy and Sonic must stop him before the two worlds are completely destroyed.
Character development is also important. In these fanfictions, we often see Bendy growing or changing as a result of his encounters with other toons. Maybe he learns new values or ways of doing things. And the other toons might also be affected by Bendy in some way. They could become more adventurous or cautious, depending on how Bendy influences them.
One common theme is the clash of different art styles. Bendy has a more dark and gritty art style, while Mickey is associated with a bright and cheerful one. Fanfictions often explore how these two different aesthetics interact.
One common theme is self - discovery. Betsy often goes on a journey to find out more about herself. Another theme is friendship. She forms strong bonds with other characters in many fanfics.
The plot might center around Frisk's sense of justice. In Undertale, Frisk often makes choices based on what they believe is right. In the BATIM world, they could see the wrongdoings and try to fix them. When they meet Bendy, Bendy could be a source of mystery. Frisk would try to understand Bendy's nature. It could also be that Frisk's ability to reset in Undertale has some sort of strange effect in the BATIM world, leading to all kinds of unexpected twists and turns in the story.
Corey and Betsy's story is likely a tale of two people falling in love. Maybe they met by chance, perhaps at a coffee shop or in a park. Their eyes met and there was an instant spark. They started to get to know each other, sharing their dreams and fears. As time passed, their love grew deeper and they became inseparable.
