The fanfiction could start with the birth of the baby. It's a moment of joy for Sharkboy and Lavagirl, but soon they realize that the baby's presence is causing some unexpected changes in their world. For example, the baby's power fluctuations are affecting the balance between the shark and lava realms. They need to find a way to stabilize this. Meanwhile, they also have to deal with the fact that their baby is growing up in a world that might not accept it easily due to its unique nature. So they work together as a family to overcome these difficulties and create a safe and loving environment for their baby.
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.
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.
The pregnancy could also be a way to bring more unity to their world. Their story of having a child together could inspire others in their world to look past differences. Sharkboy and Lavagirl would become symbols of new beginnings. They would need to teach their child about the importance of using their powers for good, and in the process, they might even discover new aspects of their own powers as they face the challenges of pregnancy and parenthood.
Max might be really excited. He could see the baby as a new hope and a symbol of the union between Sharkboy and Lavagirl. Mr. Electric could be jealous and try to cause trouble. He might see the baby as a threat to his own power or status. The other kids from the adventure might be curious and eager to help out, like playing with the baby and teaching it new things.
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.
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.
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.
The unique powers of Sharkboy and Lavagirl are a big draw. Fanfictions can explore these powers in new and exciting ways. For example, they can be used in different settings or against new enemies. Also, their relationship, whether it's friendship or something more, is really interesting to read about.
