In the 'Shark in the Dark Story', the most obvious main character would be the shark. But depending on the nature of the story, there could be other important characters too. If it's a story about the shark's journey, perhaps there could be a seagull that the shark sees flying above the water's surface during the day before it goes into the dark depths at night. Or there could be an old, wise octopus that the shark encounters in a dark cave, and they have some sort of interaction. Maybe there are also other sharks that the main shark has a relationship with, like a rival or a mate.
Since I don't know the story well, I can't say for sure. But the shark must be one of the main characters.
Since we don't know the exact story, it could be the friendly shark itself as the main character. There might also be other sea animals like fish, dolphins, or turtles that interact with the shark and are important characters in the story.
It's hard to say for sure, but perhaps the main characters are a couple of siblings. The older sibling might be protective of the younger one when it comes to the idea of sharks. And there could be a new kid in town who joins them in their exploration of the shark world. They all together form the main characters who drive the plot of the 'Shark Kids Story'.
Given the title 'shark girl tf story', the obvious main character is the shark girl. But there could be other supporting characters. For example, if the story is set in a coastal town, there might be fishermen who have seen strange things related to the girl. Or if it's a story about her fitting into a new world, there could be other 'creatures' or people in that world who interact with her. There could also be a mentor - like figure who helps her understand and control her new form or abilities if it involves a transformation.
I'm not sure as I haven't read this novel. So I can't tell you who the main characters are.
Since I don't have access to the story, the main characters could be a fisherman who gets into trouble and becomes shark bait. Or it could be a group of surfers where one of them is in a situation that makes them seem like shark bait. There could also be a marine biologist in the story who is studying sharks and somehow gets too close to the sharks and becomes the so - called 'shark bait'.
I think the shark must be a main character. And perhaps there could be some people in the park as well. They would be important as they might be the ones who interact with the shark, either by trying to avoid it or being curious about it.
Maybe there are a group of children as the main characters. They might be playing near the woods and end up getting lost in the 'dark dark woods'. Their naivete and curiosity could be central to the story as they try to find their way out while also being afraid of the unknown in the woods.
I'm not sure specifically since we don't have more details about this story. But it could be a lost traveler who is trying to find his way out of the forest.
Since I have no knowledge about this story, it might have a brave explorer as one of the main characters. Maybe there's also a wise old hermit living in the wood who helps or hinders the main character's journey.
