One common theme is friendship. Despite all the challenges they face, they remain friends at heart. Another theme is heroism. They are often depicted as heroes in the face of great danger. For example, they might be saving a planet from an alien invasion.
Another common theme is the power of love, not in a romantic or sexual sense but in the sense of caring deeply for someone. Their love for each other, whether it be platonic or romantic, gives them the strength to keep going. It can also be about the power of unity, how they come together to fight against a stronger foe.
The theme of redemption can also be found. Kerrigan, especially, may be on a journey of self - redemption after some of the things she has been through. Raynor can play an important part in this, supporting her. And a theme of hope is always present. Their story gives hope that even in a dark and war - torn universe, love and friendship can prevail.
One type of non - adult 'Raynor Kerrigan' fan fiction could be set in an alternate universe where they meet in a more peaceful setting, perhaps at a scientific research facility. They then have to use their skills and knowledge to solve a mystery that threatens the world. This kind of story allows for character development and the exploration of their personalities outside of a combat or overly sexualized context.
Friendship is also a huge theme. The bond between the trainer and their Pokemon, as well as the relationships between different trainers. There are stories where trainers team up to face a common enemy, or where they help each other out in difficult situations, all while their Pokemon are also forming their own little friendships within the group.
Adventure is a very common theme. Writers like to send Samus and Link on exciting quests together. Another theme is mutual respect. Since they are both strong and independent characters, they would likely respect each other's skills and abilities in the fan fictions.
Another theme is exploration of new worlds. The One Piece world is vast, and fan fictions can create new islands or regions with their own unique cultures, creatures, and mysteries. For example, a fan fiction could introduce an island where the laws of nature are completely different, and the Straw Hats have to adapt quickly to survive.
There could be themes related to the wizarding world in general. How Ginny and Lavender contribute to the wizarding community, or how they face the challenges in the wizarding world. It could be about dealing with dark magic threats, or their part in some magical research or discovery. These non - erotic fan fictions tend to focus on positive, character - building aspects rather than any inappropriate content.
A lot of non - adult Willow and Angel fan fictions also focus on mystery - solving. They are both involved in the supernatural world, so they might team up to solve a mystery that involves vampires, witches, or other creatures. This makes for an exciting and engaging plot. And sometimes, there's a theme of self - discovery. They both have complex identities and the stories can explore how they come to understand themselves better through their interactions with each other.
Mystery is also a big theme. There are always secrets to be uncovered in Lara Croft's world. Fan - fictions might focus on her trying to solve the mystery behind an ancient curse or a strange phenomenon. Also, character development is common. Stories could show how Lara grows as a person and an adventurer through her experiences, learning new skills and becoming more confident in the face of danger.
Friendship is a very common theme. Their bond and how they interact with each other in different situations. Pranks also play a big part as Fred and George are known for their mischievous nature.
Adventure could be another theme. They could be on a quest together, facing various challenges and enemies. In such fan fictions, the focus is on their skills, courage and how they work together to overcome difficulties, not on any erotic elements. For example, they might be exploring a mysterious dungeon or trying to solve a magical riddle.
Many non - adult Black Widow fan fictions focus on her skills and abilities. They might detail her combat techniques, her espionage skills, and how she uses her intelligence to outwit her enemies. Also, her struggle with her past and trying to find redemption is a frequent theme. Writers like to show how she is more than just a spy or a fighter, but also a complex character with emotions and a moral compass.
