Another theme could be redemption itself. Jack, having his own backstory in the game, might find a new path or purpose with Bonnie by his side. Their relationship could be a catalyst for his growth and change. Also, the wild west backdrop often leads to themes of survival and justice as they navigate the dangerous world filled with outlaws and the lawmen.
Yes, there are quite a few. You can start by checking out fanfiction websites like Archive of Our Own. Just search for 'Red Dead Redemption Jack x Bonnie' and you'll find a variety of stories with different themes and writing styles.
A common theme is adventure. Since the game is set in a wild western setting, the fanfics often involve the reader and Bonnie going on various adventures together, like hunting outlaws or exploring uncharted territories.
One common theme is redemption itself. Just like in the game, ocs often find themselves on a journey of self - discovery and atonement. Another theme is survival in the unforgiving wild west. Ocs have to deal with outlaws, harsh weather, and scarce resources.
One common theme is the idea of friendship, which is a big part of MLP. In a fanfic that combines the two, it could be about how characters from different worlds form friendships. Another theme could be redemption. Just like in Red Dead Redemption, characters in the fanfic might be seeking to atone for their past mistakes. Survival is also a possible theme, as the Wild West setting in Red Dead is a harsh place, and ponies might have to adapt to survive there.
A further theme is the passage of time. Some fanfictions explore how Arthur and Mary have changed over time. For example, Arthur's experiences in the wild and his growing disillusionment with the gang's life compared to Mary's more 'civilized' existence. How they bridge this gap, if they can, is a theme that can add depth to the stories. There are also fanfictions that focus on the idea of second chances. Maybe they meet again under different circumstances and have an opportunity to rekindle their relationship or at least come to some sort of closure.
Another theme is redemption. Given Arthur's character arc in the game, some fanfictions might explore how the reader can be a part of his journey towards redemption. Maybe the reader helps Arthur make better choices or come to terms with his past actions, adding a new dimension to his story.
Another theme is redemption. Sadie has her own past she's trying to come to terms with, and the reader might also have a troubled history. They could find redemption through their relationship, by helping each other become better people.
Friendship is a common theme. Writers often show how Bonnie and Toy Bonnie become friends despite their differences. Maybe Bonnie is the more traditional character and Toy Bonnie is the new addition, and they learn to get along.
Often, the themes revolve around the untold or alternate stories of the characters' personal lives. Since 'Red Dead Redemption 2' has such a rich world and diverse characters, fanfiction writers might use the 'lemon' aspect to add a different dimension to their relationships. Another theme could be the power dynamics between characters, which can be enhanced or explored through these types of stories. It's also possible that some fanfictions focus on the more forbidden or secret relationships within the game's setting.
The theme of justice often appears. Naruto has his own sense of justice from his ninja upbringing. In the world of Red Dead Redemption, which also has its own ideas about right and wrong, he tries to uphold what he believes is fair. He may use his jutsu to help the oppressed or fight against corrupt lawmen in the fanfiction stories.
