Romance can also be a theme, although it can be a bit more complex with three characters. Some fanfictions might explore a love triangle between Starfire, Speedy and Robin. There are also stories that focus on their growth as characters. For instance, how Speedy overcomes his insecurities, or how Starfire adapts to life on Earth better, all while in the company of Robin and with Speedy's support.
The theme of self - discovery is also prevalent. As they fall in love, both Starfire and Robin learn more about themselves. They grow as individuals while also growing closer as a couple, which is a really engaging aspect in a lot of Starfire x Robin fanfiction.
Another theme is redemption. Red X is often a character who has room for growth and change. So, many fanfictions involve him trying to make up for his past wrongs and earn the respect of Starfire and Robin.
Love and friendship are very common themes. Their relationship is often shown as evolving from friendship to a deeper romantic love. For instance, in many fanfics, they start as teammates in the Teen Titans and gradually realize their feelings for each other.
One popular theme is the exploration of their sisterly relationship. It could be about them reconciling after past differences. Another theme might be their different powers and how they interact in various situations. For example, they could team up against a common enemy using their unique abilities.
The Teen Titans has a large and passionate fan base. People who love the show are often drawn to exploring the relationships between the characters more deeply. Robin and Starfire are a popular pairing, so fans like to create their own versions of their story. It gives them a chance to imagine different outcomes for the couple, like a happily - ever - after that might not have been fully realized in the original series.
One common theme is the exploration of their cultural differences. Starfire is an alien, and Robin is from Earth. Fanfictions often delve into how they understand and adapt to each other's cultures. Another theme is the growth of their relationship, from initial attraction to a deeper, more committed love.
Perhaps a story where they are both on a mission to a new planet. On this planet, there are unique challenges like a strange energy field that affects their powers. Starfire and Robin Red have to rely on each other more than ever. They start to see each other in a new light and their relationship evolves from just being teammates to something more romantic. As they explore the planet, they also learn about a new culture that has some interesting views on relationships.
The 'soulmate' or 'destined to be together' theme is frequently explored. In these fanfics, there's an underlying belief that they are meant for each other, no matter what obstacles come their way. This could be shown through signs, prophecies, or just a deep, unexplainable connection that they both feel.
Some comic book forums can also be a good source. For example, the DC Comics sub - forum on Reddit. People might discuss and share their favorite fanfictions about Starfire, Speedy and Robin there. You could post a request asking for such fanfictions if you can't find any in the existing threads.
There could be a fanfiction where Starfire and Speedy Lemon team up to save a planet. In this story, their different personalities, Starfire's alien nature and Speedy Lemon's quick - wittedness, would create interesting interactions as they work towards the common goal of planetary salvation. This would involve them using their unique abilities in combat and also in diplomatic negotiations with the planet's inhabitants.
