One possible scenario is that the OC is a healer. In the Baki world, especially when it comes to dealing with a wild and powerful being like Pickle, a healer OC could be very important. They might initially be scared of Pickle but then realize that Pickle is also in need of some form of care or understanding. So they start to interact with Pickle in a non - combative way, which changes the dynamic between them.
Well, in Baki fanfiction, an encounter between an Original Character (OC) and Pickle could be really interesting. Maybe the OC could be a fearless fighter who challenges Pickle. It could lead to a great battle where the OC tries to use their unique fighting style against Pickle's primitive and powerful moves.
In the story, the pickle represents a special find. It's like a little hidden gem on the Christmas tree. Finding it often means getting a reward, so it adds a sense of excitement to Christmas morning.

Baki Hanma is the central figure in the 'baki light novel'. But there are also other important characters like his opponents. For example, some of the strong fighters he goes up against play significant roles as they test Baki's skills and help in his growth as a martial artist. There may also be characters who are related to Baki in some way, like his family members or his trainers, who influence his journey in the martial arts world.
Since I don't know the exact details of the 'magic pickle graphic novel', I can only guess. Obviously, the magic pickle itself is likely a main character. There might also be a sidekick character, perhaps a small animal or another strange creature that helps the pickle on its adventures.
