Jolt is not based on a comic book. It's a standalone film with a script written specifically for this project and not inspired by any pre-existing comic material.
No, Transformers Prime is an animated series and doesn't have the ability to 'watch' fanfic. Fanfic is something created by fans for fans to read, and the Transformers Prime entity doesn't have the sentience or function to engage with such written works in the way a human or a sentient being capable of reading would.
The novels are important for the franchise as they offer different perspectives. They can tell a story from the point of view of a minor character, which can be really interesting. Moreover, they can fill in the gaps between different installments of the movies or shows. For example, if there's a time jump between two seasons of an animated series, a novel can explain what happened during that time. This helps to keep the overall story of the Transformers franchise more cohesive and engaging for the fans.
