Rivalry - turned - friendship is another common one. Since they've had their share of feuds, fanfictions often show how they move past that and become closer. It makes for some really engaging stories.
I also like 'The Unlikely Alliance'. This fanfiction takes a different route by putting them in a situation where they have to team up against a common enemy that is not related to wrestling at all. It shows their adaptability and loyalty to each other.
A prevalent theme is also his redemption. Given some of the storylines in his real - life career, fanfictions often explore how he can redeem himself in different situations. It could be making up for a past betrayal or regaining the trust of his fans and peers.
One possible fanfiction could be about them teaming up in a unique tag - team situation. They might be in a fictional wrestling promotion where they have to overcome various rivals together. Their characters could develop a mutual respect and friendship as they train and strategize for their matches.
There's also 'A Day in the Life of Dean Ambrose'. It gives a detailed account of what a normal day could be like for him. It has a lot of humor and the author's descriptions make you feel like you're right there with Dean.
Perhaps a story where Seth Rollins gets involved in a cross - brand rivalry with a wrestler from another promotion. This could lead to a series of intense matches and backstage drama as they try to outwit and outperform each other.
Another angle for a fanfiction could be that they are both part of a mystery - solving adventure within the wrestling arena. There could be strange things happening backstage, like missing equipment or unexplained accidents, and they team up to find out who is behind it all. This would add an element of mystery and intrigue to their characters' relationship.
One great fanfiction could be about Seth Rollins and Nikki Bella teaming up in a mixed - tag team match against their on - screen rivals. They could show off their amazing in - ring skills and develop a unique friendship during the process.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are usually a lot of wrestling - related fanfictions there. Just use the search function and type in 'Seth Rollins and Nikki Bella' and you'll likely find some interesting reads.
One great Seth Rollins fanfiction is 'The Ascent of Seth Rollins' on FanFiction.net. It really delves into his journey in the WWE, his character development, and his relationships with other wrestlers. The story is well - written and keeps you engaged from start to finish.
