Their adventures would likely become more cautious. Instead of just rushing into danger, they would have to think about the safety of the unborn child. So, their battles might be less impulsive.
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.
Another idea is a story where Sharkboy and Lavagirl go on a journey to discover the origin of their powers. They might encounter some ancient guardians or face challenges that test their friendship and make them grow stronger as they learn more about themselves and their abilities.
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.
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.
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.
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 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.
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.
A believable OC for Sharkboy and Lavagirl fanfiction can be created by carefully considering various aspects. Begin with their origin. Were they born with their powers, or did they acquire them through some event? This origin story can be a great way to add depth. Next, their abilities should have limitations. No one is all - powerful in this world. If they have a power related to the wind, for instance, maybe it only works in certain weather conditions. Their emotions also play a role. If they are scared of heights, this can create interesting situations when they have to fly with Sharkboy. By taking all these factors into account, you can create an OC that feels like it belongs in the Sharkboy and Lavagirl universe.
