Transformation is a big theme. Since he has the ability to change his appearance, fanfics often play with this aspect, showing different forms he can take and the consequences of those changes. Revenge is also sometimes a theme, as he has his own grudges in the original stories.
Some fanfics might put them in an alternate universe scenario. Maybe in a world where they are part of a superhero team together. Cassandra could be the stealth and combat expert while Basil could bring something unique to the table, like a knowledge of some arcane or forgotten arts. The fanfic could explore how they grow as characters within this new team dynamic.
There's also 'Basil Karlo: Redemption'. It focuses on the idea of Basil Karlo seeking redemption for his past actions. The character development in this fanfic is quite remarkable, and it gives a fresh perspective on the character.
Some specialized Batman or DC Comics fanfic communities or forums might also be a good source. Members often share their own fanfics or know of great ones that are not as well - known on the bigger platforms. You can interact with other fans there and ask for recommendations specific to Cassandra Cain and Basil Karlo.
The origin story of Basil Fawlty typically involves his creation for the 'Fawlty Towers' series. He was brought to life by John Cleese, who based the character on a real hotelier he had encountered during his travels. This real - life experience inspired the comically inept, short - tempered and socially awkward Basil that we see in the show.
One great 'Basil and Ratigan Fanfic' is 'The Great Rivalry' which delves deep into the psychological aspects of their relationship. It shows how their rivalry is not just about the chase but also about mutual respect in a strange way.
A 'basil dbs fanfic' could be about various things. It might be a fan - made fictional story related to the Dragon Ball Super (DBS) universe that features a character named Basil. It could involve Basil's adventures, his relationships with other DBS characters, or it could even be a completely new and unique storyline set within the DBS world that just uses Basil as a central or supporting character.
Since I don't have the details of the 'basil top stories', it might be that they are stories centered around the uses of basil in different cultures. For example, in Italian cuisine, basil is a key ingredient in pesto. Maybe the stories talk about how basil has been used in traditional dishes across the world, or perhaps they are about the health benefits of basil, such as its antioxidant properties.
I think AuthorA is really good. Their Basil and Olivia fanfics are known for their detailed characterizations. They manage to bring out the nuances of Basil and Olivia's relationship in a very believable way.
