Who are some potential new characters that could be added to a Sharkboy and Lavagirl crossover fanfiction?

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.

Luffy from One Piece could also be a great addition. His carefree yet strong - willed nature would create some fun dynamics. He might be amazed by the Air Gear skating and try to incorporate it into his own fighting style on the Grand Line. Plus, his rubber body could lead to some really unique skating stunts.

A new character could be a therapist who has a unique approach to helping the main character. This therapist could introduce new ideas and methods of healing that the main character hasn't encountered before.

A healer from a far - off land could be an interesting addition. This character could bring in new knowledge of magic and medicine that the existing characters are unaware of. Maybe they have a special connection to nature that allows them to heal in ways not seen before in the story.

A young Martian inventor could be a great addition. This character could create unique gadgets and machines that help the protagonists in their adventures. For example, a flying device that can travel at high speeds across Mars.

A mysterious traveler passing through the town could be a new character. This person has seen many strange things in their travels and is not afraid of Edward. In fact, they see his potential and encourage him to leave the town and see the world.

A healer character could be added. This healer could be the one who discovers a hidden power within the apprentice that could change the course of their journey. Another potential character could be a mysterious traveler. This traveler has seen many different worlds and has knowledge that could either help or hinder the apprentice.

In a Space Jam: A New Legacy fanfiction, a character like a time - traveling video game historian could be introduced. This character knows all about the history of video games and basketball in the digital realm and can use this knowledge to help the Tune Squad. Another new character could be a shape - shifting blob from a gooey video game. It can transform into different objects or even other characters to help the team in various ways. Also, a talking basketball that has its own mind and can offer advice and pep talks to the players would be an interesting addition.

A brilliant detective from another city could be added. This character could be initially a rival to Miss Scarlet and the Duke, but later they all team up to solve a really tough case. He could have his own unique methods of investigation.

A shinobi from a hidden village that was destroyed long ago. This character could carry the secrets and unique jutsu of their fallen village and seek revenge or redemption in the Naruto world.
