Often, themes like power dynamics play a role. Scar being a more complex character with his own motives and Sarabi having her own strength. There could also be themes of forgiveness. Scar has done some bad things, and Sarabi might have to forgive him in the fanfic for a relationship to develop. Also, exploration of their pasts and how it affects their present relationship can be a theme.
One common theme could be redemption. Maybe Scar is given a chance to change and Sarabi sees a different side of him. Another might be forbidden love, since in the original story they are not really a couple.
I'm not sure of specific 'scar x sarabi fanfic' stories off the top of my head. But you can try looking on fanfiction websites like Archive of Our Own. There are often a wide variety of fan - created stories for different pairings.
Often, themes like love and loyalty might be common. Since Sarabi is a character, stories could revolve around her relationships and how she navigates through different situations with loyalty to her beliefs or her loved ones.
One common theme is survival. Since both Lex and Scar are often in a hostile environment, their fight for survival is a key element. For example, in many fanfics, they have to find food and shelter while avoiding other dangerous creatures.
Friendship could be a common theme. It might explore how Scar and Alexa become friends and the adventures they have together.
A common theme could be forbidden love. Since Scar is often portrayed as a bit of an outcast and Sarafina is part of the pride, their relationship might be seen as something that goes against the norms of the pride. Another theme could be redemption. Maybe in some fanfics, Scar's relationship with Sarafina makes him want to change his ways.
Love and acceptance is also a theme. There could be stories where a character helps Anakin accept his scar, whether it's a romantic interest or a close friend. This could involve the other character seeing past the physical imperfection and loving Anakin for who he truly is, which in turn helps Anakin come to terms with his own self - image.
One common theme is redemption. Scar, with his past actions, and Ed, with his own journey of self - discovery, often find redemption through their relationship in the fanfics.
There could be a fanfiction that delves into their past. Maybe they had some unspoken connection when they were younger, and the story unfolds to reveal how their relationship could have developed differently from what we saw in the original. It could show how Scar's jealousy and Sarabi's loyalty played out in new and unexpected ways.
One non - adult theme could be redemption. For example, a story where Scar has a change of heart and tries to make amends with Sarabi and the rest of the pride. Sarabi could be initially skeptical but gradually come to see the new Scar.
Another theme could be her relationship with other characters. For example, her relationship with Scar. Some fanfiction might explore how she dealt with Scar's rule during Simba's absence. It could show her as a resistance figure within the pride.
