Well, of course, Daniel is a main character. He is often the focus as the story usually revolves around his actions and his relationship with the other bionic characters from the Lab Rats series.
The main characters from the original Lab Rats series also play important roles. For example, Adam, Bree, and Chase. In the fanfiction, their interactions with Daniel can create a lot of drama and interesting plot twists. They might be trying to stop Daniel from his evil plans or trying to help him become a better person depending on the plot of the fanfiction.
The main characters are Adam and Bree. Adam is typically portrayed as strong and a bit of a brute at times, but with a good heart. Bree, on the other hand, is fast and intelligent. Together, they make an interesting pair in the fanfiction world.
The main characters are usually the Lab Rats themselves. They are the ones with superhuman abilities and unique personalities. Each of them brings their own skills to the table whether it's super strength, super speed, or intelligence.
Obviously, Taylor and Leo are the main characters. Taylor is often portrayed as a smart and independent character. Leo, on the other hand, is usually shown as someone who is kind - hearted and has a good relationship with the lab rats.
The main characters would obviously be the lab rats and Donald. The lab rats are likely to be the pursuers, and Donald is the one being chased.
The main characters are Billy and Kelli, of course. They are likely to be at the center of whatever stories are created in the fanfiction.
The main characters are typically the Lab Rats - Adam, Bree, and Chase. They are bionic teens with unique abilities. And of course, Victor Krane, who is often the antagonist in the original series but can be portrayed in different lights in fanfiction. He is a brilliant but often misguided scientist. Sometimes, other characters like Mr. Davenport or Leo may also be important in the fanfiction, depending on the plot.
One interesting Lab Rats Daniel fanfiction could be about Daniel coming back with new powers and trying to take over the lab again. He might form unexpected alliances this time.
Most likely the two lab rats in love are the main characters. But there could also be some supporting characters like the scientists who take care of them or other lab animals.
Obviously, Skase is a main character. He's the center of the fanfiction usually. Then there are the members of the Elite Force like Bree, Chase, and Kaz. They often interact with Skase in different ways, either as friends, allies, or sometimes rivals depending on the plot.
Definitely Adam, Bree, and Chase. Adam with his super strength could be trying to break through the barriers of the speed trap. Bree, with her super speed, might be both a target of the trap (as it's speed - related) and also a key to getting out. And Chase, being the intelligent one, would be figuring out how the trap works and formulating plans to escape. There could also be Mr. Davenport involved, as he is their mentor and might be trying to help them from the outside or get trapped with them and use his technological knowledge to find a solution.
