One possible plot could be that the bionic heroes from 'Lab Rats' somehow end up in the dojo from 'Kickin It'. There, they meet the karate students and initially there are some misunderstandings due to their different worlds. But then they realize they can learn from each other. The bionic superpowers could be combined with the karate skills in an epic battle against a common enemy, like a group of high - tech thieves who want to steal both the bionic technology and the secret karate techniques.
A cool plot could be that a scientist in the 'Lab Rats' universe has created a portal that accidentally transports some of the 'Kickin It' characters into the bionic lab. The 'Kickin It' gang is shocked by the high - tech environment. They soon team up with the 'Lab Rats' when they discover that an escaped bionic experiment is running loose in the city and causing chaos. The karate skills of the 'Kickin It' crew and the bionic powers of the 'Lab Rats' are used to track down and stop the experiment.
I think Chase from 'Lab Rats' and Jack from 'Kickin It' would be an interesting pair. Chase is the smartest of the bionic siblings and Jack is quite street - smart in the karate world. Their different ways of thinking and approaching problems would create a lot of interesting interactions. For example, Chase might be too reliant on his bionic intelligence, while Jack would show him how to use intuition and quick thinking in a fight.
One common theme is crossovers. Writers like to bring the characters from Lab Rats and Kickin It together and see how they interact. Another theme could be character growth. For example, taking a character from one show and exploring how they would develop in the world of the other show.
One possible plot could be that Naruto, with his godlike powers, somehow gets transported to the world of Lab Rats. He could team up with the Lab Rats to fight a common enemy. Maybe a powerful villain from Naruto's world has also found a way into the Lab Rats' world and is causing chaos. Naruto's ninja skills combined with the high - tech abilities of the Lab Rats would make for an exciting adventure.
A cool plot could be that there is a cross - dimensional rift that starts causing chaos in both universes. The Lab Rats' Davenport decides to work with the Hokage in Naruto's world to close the rift. The Lab Rats and Naruto characters have to combine their skills. For example, Chase's super intelligence could be used to analyze the rift, while Naruto's Rasengan could be a powerful weapon against any threats that emerge from the rift. Along the way, there would be cultural clashes and lots of interesting interactions between the two groups.
A great plot for a fanfiction could involve Brasé getting infected with a strange bionic virus on Bionic Island. This virus starts to affect his bionic abilities in unpredictable ways. At first, he gains some super - strong powers but then he starts losing control. The other Lab Rats have to race against time to find a cure. They explore different parts of the island, meet new characters who might have the knowledge to help, and in the process, they learn more about the dark side of bionic technology. Brasé's struggle with the virus and his fear of losing himself could be a very emotional and engaging part of the story.
The plot might involve a scientist who has worked on both the bionic enhancements for the Lab Rats and has some connection to an experiment related to the Avengers. This causes a rift in space - time that brings the two groups together. The Lab Rats could learn a lot from the Avengers about teamwork on a grander scale, and the Avengers could be impressed by the unique bionic abilities of the Lab Rats.
It could be about the Lab Rats getting trapped in a high - speed situation, like being in a malfunctioning super - speed device. Maybe they have to find a way to break free while also dealing with the side effects of the speed trap.
One possible plot could be that Kagome somehow gets transported into the Lab Rats' world. Maybe she mistakes their high - tech lair for a strange youkai (demon) lair at first. The bionic heroes could be initially suspicious of her, but then realize she has her own kind of 'powers' in the form of her spiritual abilities and her sacred arrows. Together, they could team up to fight a common enemy, perhaps an evil scientist who wants to use both Kagome's spiritual energy and the bionic technology for his own malicious purposes.
It could be that the story focuses on the unique courtship rituals of lab rats within the scientific setting. They may bond over shared experiences like running through mazes or being exposed to certain stimuli in the lab. The love story might also involve how they support each other during difficult tests.
One possibility could be that Marcus kidnaps Leo to use him as a bargaining chip against the Lab Rats. Maybe he wants access to the bionic technology they possess. Marcus might think that by having Leo, he can force the others to give up their secrets or help him gain more power.
