Another theme is the exploration of relationships. Female characters in these fanfictions often form different kinds of relationships with Hellboy or other characters from the Hellboy universe. It could be a friendship, a mentorship or even a romantic relationship in some cases.
The theme of self - discovery also appears frequently. Female characters in female Hellboy fanfiction are often on a journey to discover their true selves, their powers, and their place in the world of Hellboy. This could involve coming to terms with their heritage or uncovering hidden abilities within themselves.
One common theme is the clash of different mythologies. When Hellboy crosses over with other universes, like the Norse mythology - based Thor universe, you get a mix of different supernatural elements. Another theme is teamwork. For example, when Hellboy teams up with characters from other franchises, they have to learn to work together despite their differences.
One common theme is sacrifice. Given their dangerous line of work, a lot of fanfics will have one or both of them sacrificing something for the other. Also, the theme of acceptance is there. Hellboy's appearance and Liz's powers are things that they might have to accept in themselves and in each other more fully in fanfiction stories. And of course, there's the adventure theme as they often go on quests together in these stories.
One common theme is power. How the Naruto - Hellboy descendant deals with their unique powers that come from both worlds. Another could be identity, as they are a part of two very different universes. And of course, there's often the theme of fighting against evil, just like in both the Naruto and Hellboy original stories.
One common theme is the discovery of self - worth. The oc often starts out feeling out of place or unimportant, but through their interactions with Hellboy, they realize their own value. For example, they might find that their unique skills or personality traits are exactly what is needed to help in a particular situation.
The theme of adaptation is also prevalent. Characters from both sides have to adapt to the new and strange world they find themselves in. For instance, the heroes in My Hero Academia might have to adapt to the more gritty and dangerous world of Hellboy, and vice versa. This can lead to character growth and new relationships being formed.
One common theme is their friendship. Their different personalities - Hellboy's brashness and Abe's more reserved nature - often lead to comical interactions. For example, when they are on a mission together, Hellboy might rush in while Abe is still making a careful plan, and the chaos that ensues can be really funny.
Some common themes in Once upon a time Hellboy fanfiction include the idea of family. Hellboy's adoptive family and his relationship with them are often explored. Another is the concept of destiny. Is Hellboy fated to be a hero or is there a different path for him? And then there's the theme of the supernatural world. Fanfictions might expand on the different creatures and beings in Hellboy's world, how they interact, and how Hellboy fits into this complex supernatural ecosystem.
One common theme is redemption. Female characters often see the good in Snape despite his outwardly cold and sometimes cruel demeanor. They try to bring out his better side.
A common theme could be the exploration of femininity within a powerful and mythical Pokémon like Reshiram. Another might be relationships, like with a trainer or other Pokémon.
Survival is also a big theme. The female Indoraptor has to deal with various threats in the fanfiction worlds, whether it's from other predators or from human hunters. How she overcomes these challenges and survives in a hostile environment is a key aspect. Some stories also focus on her family or origin, exploring where she came from and if there are others like her, which ties into the survival theme as she might be the last of her kind.
