Another idea is to write a story set in the future. They have grown up and are training the next generation of heroes. Along the way, they recall their own early days as heroes and how their relationship has evolved over time. This could show their growth both as individuals and as a couple, and how they pass on their values to the new heroes.
Perhaps a story where Sharkboy and Lavagirl take a break from their heroic duties and just have a day exploring an underwater city. They could discover new things about each other and their feelings could develop further in a more relaxed setting. It could involve some light - hearted moments like Sharkboy trying to understand the nuances of Lavagirl's fiery personality while she tries to adapt to his more aquatic ways.
One idea could be exploring their adventures in a new dimension where they have to face a powerful enemy together. Their relationship could deepen as they rely on each other's unique powers.
A cool Sharkboy and Lavagirl fanfiction could be that they swap powers for a day. It would be really interesting to see Sharkboy trying to control lava and Lavagirl swimming around as a shark. Or perhaps a story where they meet other kids with similar but different elemental powers and they all form a team to protect a magical place that is both underwater and volcanic. Also, a fanfic where they get lost in a strange dimension and have to use their combined wits and powers to find their way back home.
An interesting plot could be an OC who is a tech - genius and creates new gadgets for Sharkboy and Lavagirl. For example, a device that can enhance their powers or help them travel faster. The OC could also have a personal vendetta against a villain who is using technology to disrupt the balance in their world. This would lead to a story where the OC, Sharkboy, and Lavagirl team up to defeat the high - tech bad guy. It could involve a lot of action - packed scenes in a high - tech city or a secret lair.
Perhaps they could go on a journey to a new magical world where they discover new aspects of their relationship. In this world, they might have to prove their love in different ways, like solving puzzles together.
One idea could be that Sharkboy and Lavagirl find themselves in a new dimension where they meet characters from another story. They have to team up with these new characters to defeat a common enemy that threatens both their worlds. For example, they might encounter a powerful ice - themed villain who is freezing over all the water in their world and the new world they've entered. Sharkboy's ability to control water and Lavagirl's heat - based powers would be put to the test as they try to stop this villain.
One plot twist could be that Sharkboy turns out to be from a future where Lavagirl has become an evil dictator. He travels back in time to stop her from turning bad. This completely flips their relationship dynamic and adds a whole new layer of complexity to the story.
First, think about the characters' personalities. Sharkboy is brave and connected to the ocean, while Lavagirl is strong - willed and has her fiery nature. Start with a simple scenario, like them meeting in an unexpected place.
The kiss in the fanfiction also serves as a plot - driving element. It can change the course of their story. For example, it could be the turning point where they decide to face their enemies together more united than ever, or it could be a moment of realization for their true feelings that then leads to further character development.
One common theme could be the power of their love overcoming challenges. Since they both have unique powers, there might be stories where their love helps them face external threats.
The kiss is special because it represents the union of their powers in a way. Their relationship is not just about romance, but also about how they complement each other. The kiss can be seen as a physical manifestation of that harmony between them.
Well, there are some really cool fanfictions out there. One that I remember has Sharkboy and Lavagirl going on an adventure beyond their usual world in the movie. They encounter new challenges and have to use their powers in unique ways. It's a really exciting read.
