One popular theme is the Dinobots' origin stories. Writers often explore how they were created and what led to their unique dinosaur - like forms. Another common theme is their relationships with the other Autobots and Decepticons. How they interact in battles and in the Autobot base.
One great Transformers Prime Dinobots fanfiction is 'The Awakening of the Dinobots'. It shows how the Dinobots are discovered and brought into the fight. It has really cool action scenes and stays true to the characters' personalities from the show.
Their personalities could be developed through their experiences. For example, if a baby Dinobot is constantly facing difficult situations where it has to be brave, it will grow to be more courageous. If it is often in situations where it needs to think quickly, it will become smarter.
The Dinobots are just so cool. They're big, powerful, and have a unique look. Fanfiction allows fans to explore more of their backstories and potential adventures that we might not see in the original show. For example, we can see them in different battles or how they interact with new characters.
Social media groups dedicated to Transformers can also be a great source. On Facebook or Reddit, there are groups for Transformers fans. You can post a request asking for Dinobots fanfiction. Members are usually quite helpful and might point you to some great stories they've read or even written themselves.
A plot could revolve around the baby Dinobots befriending a group of small, local Cybertronian creatures. These creatures are being threatened by a natural disaster on Cybertron. The baby Dinobots, with their unique skills and courage, decide to help the creatures survive the disaster, all while learning valuable lessons about friendship and responsibility.
