Common themes in Tifa fan fiction include her role as a protector. She's often depicted as safeguarding her friends and the people in her community. Her internal struggles are another theme. These could be about her self - worth or her place in the world. And her connection to the overall story of the game world is a theme too. Fan fictions might expand on how she fits into the grand scheme of things and how she influences the events around her.
One common theme could be the anticipation and preparation for the new life. Another might be how the relationships around Tifa change due to her pregnancy.
One common theme is friendship. Writers often explore how an original character can form a deep and meaningful friendship with Tifa. For example, they might start as strangers and then become close allies.
Love and romance are also quite common themes. Given Tifa's relationships with other characters, fanfics often play with the idea of love in different ways. It could be a slow - burning love story or a more complex love triangle - like situation.
One frequent theme is friendship - turned - romance. They start off as comrades or just acquaintances and then gradually develop deeper feelings for each other. There's also the theme of power - combining. Given their individual strengths from their original games, fanfictions may depict them using their powers in unison to overcome great obstacles. It's really interesting to see how authors blend these two characters' traits and storylines.
One common theme is unrequited love. Since their relationship in the original game is not fully explored, fanfictions often play with the idea that one of them has feelings that the other is unaware of at first. Another theme is redemption. Zack might be seen as trying to redeem himself in Tifa's eyes in some stories.
Love and relationships are common themes. There could be romantic love triangles between Cloud, Tifa and Aerith, or platonic love that shows their deep friendship. Another theme is self - discovery. Each character has their own journey of finding out who they really are. Cloud is often on a quest to understand his true identity, Tifa with her own sense of self in relation to her past and Aerith with her Cetra identity.
One common theme is the exploration of their unspoken love. In the game, their relationship is complex and full of nuances, and fanfiction often dives deeper into those unexpressed feelings. For example, how they might be secretly in love but too shy or preoccupied to admit it.
Another theme is growth. The characters often grow as individuals within the relationship. For example, they might overcome personal fears or insecurities because of the influence of the other. In some fanfics, they also grow in their understanding of the complex world around them.
A common theme is friendship. Many fanfics explore how Aerith and Tifa, despite their initial differences, become close friends. Another theme is mutual support. They often rely on each other in difficult situations. For example, in some fics, when one is in danger, the other comes to the rescue. And there's also the theme of female empowerment. Together, they show that women can be strong and independent and still have a great relationship.
I'm not aware of any common themes as such in this specific type of fanfic since it's not a very common or mainstream pairing. But generally in fanfics, themes could include exploration of their relationship, how they interact in different scenarios, and perhaps some kind of adventure or conflict that brings them closer together.
