In Lab Rats Elite Force fanfiction, if Bree gets hurt, the characters' reactions would be significant. Her brother, Chase, would no doubt be extremely worried and would do everything in his power to help her. He might even put himself at risk to find a solution.

Their reactions would not only show their care for Bree but also the strong bond that exists within the team.

One possible fanfiction could be about Bree and Skylar going on a secret mission together. They might have to rely on each other's unique abilities to overcome various obstacles. For example, Bree's super speed could help them quickly reach different parts of the mission area, while Skylar's energy blasts could be used for defense or attacking enemies. It could also involve some character development, like them learning to trust each other more deeply as they face challenges side by side.
One possible scenario in a Lab Rats fanfiction where Bree gets hurt is that she gets injured during a mission. Her bionic abilities might malfunction because of the injury. This would create a sense of urgency as the team tries to fix her. They could search for a new technology or meet an unexpected ally who has the knowledge to repair her. Meanwhile, Bree would have to deal with the physical pain and the fear of not being able to use her bionics again.
One possible fanfiction could be where Bree and Chase go on a secret mission together. Away from the rest of the team, they face a new kind of villain that has powers they've never seen before. They have to rely on each other's unique abilities, Bree's super speed and Chase's super intelligence. As they work together, they start to realize their feelings for each other are deeper than just friendship.
A plotline could be that Bree and Skylar are framed for a crime they didn't commit within the Elite Force. They then have to work together to clear their names. They would need to investigate who the real culprit is while also avoiding being caught by their own teammates. This would create a lot of tension and mystery in the story.
There might be a fanfiction where Bree tries to redeem Marcus. Since Marcus has had a dark past, Bree could use her positive influence to turn him around. This could involve many adventures together where Bree shows Marcus the value of friendship and doing good. For example, they might have to rescue hostages held by a common enemy. Through these experiences, Marcus begins to question his old ways and slowly changes for the better.
Another plot could involve Bree and Chase being sent back in time to when the Lab Rats first got their bionic powers. They have to be careful not to change the past too much, but also use their knowledge from the future to help the younger versions of themselves and their friends. This would create a lot of interesting interactions and challenges.
One common theme could be Bree facing physical challenges that cause her harm, like malfunctioning bionics. Another might be emotional hurt, such as betrayal by a friend or family member within the 'Lab Rats' universe.
To write a good fanfiction, you need to understand the characters well. For Bree, remember her super speed and her kind heart. Marcus is more complex, with his villainous past. You could start with a simple idea, like them having to compete in a training exercise. As you write, let their personalities shine through. Add some conflict, like Marcus being tempted to use underhanded tactics but Bree stopping him. And don't forget to have a satisfying resolution at the end.
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.
