One common theme is the sense of loss. Without Bree, the other three characters feel incomplete and they often have to deal with this feeling throughout the fanfiction. Another theme is unity. They need to stick together more than ever to face the challenges that come their way.
I've read a 'Lab Rats Three Minus Bree' fanfiction that focuses on the emotional side of the three characters. They struggle with the absence of Bree and how it has affected their team dynamic. It's a very well - written piece that really makes you feel for the characters.
Well, a big theme is family. Given her situation in the lab and with her 'creators', family dynamics play a role. Sometimes it's about finding a true family among her friends. Also, the theme of power and responsibility. Bree has these great powers, and fanfictions often deal with how she uses them for good or struggles with the responsibility that comes with them. There's also the theme of adventure. She often goes on exciting adventures in the fanfictions, exploring new places and facing new challenges.
Growth and self - discovery also feature often. As they face challenges together, both Bree and Ethan often grow as characters. They learn more about their own strengths and weaknesses and how to better support each other. This can be seen in fanfictions where they are put in difficult emotional or physical situations.
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.
Friendship is a common theme. The OC often becomes a close friend to Bree, and they go through various challenges together.
One common theme is the exploration of their relationship. Since they are both bionic heroes, there could be themes about how their powers interact in their relationship. For example, they might use their bionic abilities to protect each other in a romantic way.
A lot of fanfictions focus on their growth as characters. For instance, how Leo becomes more confident in using his abilities or how Bree overcomes certain challenges related to her bionic nature. There are also stories that revolve around their relationships with other characters from the show, like their friends or enemies. These relationships are often developed further in fanfiction, adding new dimensions to the characters. Some fanfictions might also explore what would happen if they were in different time periods or alternate universes, which is always an interesting concept.
Love or romance is also a popular theme. Writers might create a romantic relationship between Bree and Sebastian, exploring how they fall in love, deal with relationship problems, etc. Additionally, there could be themes related to self - discovery. The characters in 'Lab Rats' are constantly evolving, and fanfictions may focus on Bree and Sebastian's individual growth and how they help each other in that process. This could involve them learning new powers, facing their fears, or understanding their place in the world.
One common theme could be the anticipation and preparation for the baby. It might show Bree and Chase getting ready for the new arrival, like setting up a nursery or buying baby stuff.
One common plot element is the rescue mission. Usually, her brothers, Chase and Adam, team up to find and save her. Another is the mystery behind the kidnapping. It could be related to a new villain who wants to use Bree's bionic abilities for their own evil plans.
