Well, mystery is a big theme. Since Bendy comes from a rather spooky and unexplained world in the original concept, fanfictions often play on that. Also, the theme of trust. As the reader gets closer to Bendy, there's a development of trust between them. And there's also the theme of discovery, like the reader discovering new things about Bendy and his world.
One of the main themes is the contrast between the normal world the reader is from and Bendy's ink - soaked world. This contrast creates a lot of interesting situations. Another common theme is protection. Sometimes Bendy protects the reader from the dangers of his world, and other times it's the reader who protects Bendy in some way. And of course, there's the theme of connection, whether it's a spiritual or emotional bond that forms between them.
One common theme is the exploration of the strange and spooky world of Bendy. The reader often finds themselves in this otherworldly place and has to navigate it while interacting with Bendy. Another theme is the relationship that develops between the reader and Bendy, which can range from friendship to something more romantic. It's also common to see themes of mystery and discovery as the reader tries to figure out the secrets of the studio and Bendy's existence.
Friendship or a strange relationship with the characters, especially Bendy, is also common. The reader might start out scared but then form an odd bond with Bendy as the story progresses. For example, in many fanfictions, they work together to escape the dangerous ink world.
One common theme is the exploration of the spooky and mysterious world of the game. The reader is often thrust into this strange environment and has to navigate it. Another theme is the relationship between the reader and Bendy, which can range from fear - based to a more sympathetic connection. For example, in some fanfics, Bendy is seen as a misunderstood creature, and the reader tries to understand him.
The theme of the power struggle often appears. The OC may have some special abilities that either put them at odds with Bendy or make them a valuable ally. Another frequent theme is the exploration of the unknown. The Bendy world is full of mysteries, and the OC is usually the one to start exploring and uncovering them. And of course, the theme of character growth, as both Bendy and the OC change and develop through their interactions.
One common theme is redemption. Henry often tries to redeem Bendy from his dark or villainous ways. Another theme is friendship. Despite their differences, they form a bond that is explored in many stories.
A common theme is the clash of their different art styles. Cuphead has that rubber - hose, 1930s - style animation while Bendy is more of a creepy, old - timey cartoon look. Another theme is adventure. They often go on quests together in fanfictions.
The theme of self - discovery also pops up. As they interact, both Bendy and Sans may learn new things about themselves. Maybe Sans discovers a more creative side through Bendy's influence, or Bendy becomes more confident in his abilities with Sans' support.
One of the common themes is definitely cooperation. Since they are both toon characters, they often have to work together to face challenges. There are also themes of self - discovery. As they interact with each other, they learn more about themselves. For example, Bendy might discover a more caring side of himself when he's with Oswald, and Oswald might find that he can be more daring with Bendy around. It makes for some really engaging stories.
Survival is also a theme in some Henry x Bendy fanfiction. They could be in a dangerous situation, like a collapsing game world or facing other menacing creatures. In these stories, their relationship is tested as they fight for their lives and rely on each other to make it through tough times.
One common theme is friendship. Since Bendy and Cuphead are from different franchises, a lot of fanfiction focuses on how they become friends. For example, they might start off as rivals but then realize they have more in common than they thought.
