In some Planet Blue fanfics, there could be a group of rebels who are fighting against an oppressive regime on the planet. These characters would add a lot of drama and action to the story. Each of them might have their own backstories and motives for joining the rebellion, which makes the story more complex and interesting.
The main characters are Blue and Pearlven, of course. Blue is often depicted as a brave and curious character, while Pearlven is more of a wise and calm one.

The title 'Blue or Blue Forgive Prof Oak' clearly points to Blue and Professor Oak as main characters. Blue could be a young and ambitious character, perhaps a trainer. Professor Oak, on the other hand, is an older, wiser figure. In the fanfic, their relationship is likely to be at the core. There may be side characters that support or oppose their actions, but Blue and Oak are the ones that the plot will mostly revolve around.

Often, the main character could be the person who owns or wears the blue jeans. They are central to the story as the jeans are usually closely associated with their experiences.
Typically, the main characters in the 'Blue Lagoon: The Awakening' fanfic would be the same as in the original work.

Their names may vary depending on the specific interpretation in the fanfic, but generally, they are the central figures around which the story revolves.
Since I don't know the specific 'bolt from the blue fanfic', I can't say for sure who the main characters are. It could be the main characters from the original work that the fanfic is based on, like if it's a fanfic of a TV series, it might be the lead actors from that show.
