Most likely the main characters from Bikini Bottom like SpongeBob, Patrick, Squidward, Mr. Krabs, and Plankton. Since it's set in that world, they would probably be central to the story.
In a 'Bikini Bottom' - based fanfic, I would expect to see SpongeBob as a main character. He is the cheerful, sponge - like character who lives in a pineapple under the sea. His best friend Patrick, the starfish, would also be likely to be a main character. Then there are the other well - known characters like Squidward Tentacles, who is always annoyed by SpongeBob and Patrick's antics. Mr. Krabs, the money - loving crab who owns the Krusty Krab, and Plankton, the tiny but devious villain who wants to take over the Krusty Krab, would also be among the main characters in such a fanfic.
Given that it's a fanfic about Bikini Bottom, the main characters would almost surely include SpongeBob SquarePants. He is the most iconic character there and often gets into all sorts of situations. Patrick would also be a key character as his friendship with SpongeBob is a big part of the show. And of course, Mr. Krabs with his love for money and Squidward with his grumpy nature would also play important roles. And we can't forget Plankton who is always trying to steal the Krabby Patty formula.
I'm not sure specifically as it could be a very niche or fan - created story. It might be about events that happen continuously (around the clock) in the Bikini Bottom setting, perhaps involving the characters from that world in various adventures or daily life situations.
Since I have no information about this fanfic, it's impossible to tell who the main characters are. But in most fanfics, the main characters are often those who drive the story forward. So in this 'bend around the wind fanfic', they could be characters with special abilities related to the wind, like a wind - controlling hero or a group of adventurers who are constantly challenged by the wind's power.
Since I don't know the specific 'family clock fanfiction', it's hard to say. But it could be the family members who own the clock, like the parents, children, or grandparents.
I don't know as there is not enough information given. It could be a group of adventurers, or maybe a single protagonist who is exploring the clock tower in the game - inspired story.
There could be a group of characters. For example, a team of archaeologists who are interested in the historical significance of the clock tower. Among them, there may be a leader who is brave and decisive, a tech - savvy person who can figure out the mechanical parts of the tower, and a historian who knows the backstory of the place.
I don't know the specific main characters in this novel as I haven't read it. But they could be brave adventurers, perhaps a young hero or heroine with a special skill or power.
I don't know for sure without more details about the 'clock tower game story'. It could be a young hero who is drawn to the mystery of the clock tower.
Since I haven't read the 'doomsday clock graphic novel', it's hard to say exactly. However, it might have characters such as a journalist who is uncovering the truth about the approaching doomsday. There could also be government agents who are either trying to cover up the situation or actually do something to stop it. And maybe there are ordinary people who find themselves in extraordinary circumstances and have to rise to the challenge to save the world.
There's no way to know without more information. However, it might be typical characters like a brave hero or heroine, a wise old man who gives clues about the game around the clock tower, and perhaps some antagonists who try to disrupt the game or steal something important related to the clock tower.
I'm not sure exactly who the main characters are as I haven't read all of it. But it could be the astronauts if there are space exploration stories in it.
