I'm not entirely sure specifically what an 'accelerator worm fanfic' is about as it could vary greatly. It might be a fan - created story related to something named 'accelerator' and 'worm', perhaps characters or concepts from a particular game, anime or other media. Without more context, it's difficult to say for sure.
One common theme is the exploration of their relationship. Given their different personalities and powers in the original series, fanfics often delve into how they interact, whether it's a friendship, rivalry, or something more. For example, some fics might show Accelerator slowly coming to respect Misaka in a new way.
The relationship development between Accelerator and the OC is crucial. It should be believable and not rushed. Maybe they start off as enemies or strangers and gradually grow to understand and care for each other. The writer should also be able to capture Accelerator's complex personality accurately. If it's an AU (Alternate Universe) fanfic, the new setting should be well - thought - out and add something new to the story. For instance, if it's a modern - day high school AU, how would Accelerator and the OC interact in that context? All these elements combined can make a great Accelerator x Oc fanfic.
