Who are the main characters in 'acran science fiction'?

I'm not sure specifically which works are in 'acran science fiction' as it's not a widely known mainstream term. It could be a very niche or new area of science fiction. Maybe it features unique alien species or advanced technological concepts that are distinct to this particular type of science fiction.

Master Chief is definitely a central character. He's the face of the human resistance in many ways. Cortana is not just an AI, she's like a partner to Master Chief, with her own personality and intelligence. The Arbiter's story is interesting as he starts on one side of the conflict (the Covenant) and then has to make some tough choices and his journey is a big part of the narrative. There are also other characters like Dr. Halsey who is involved in creating the Spartans and her actions have far - reaching consequences in the Halo universe.

Colonel Jack O'Neill is one of the main characters. He's a tough military leader. And then there's Dr. Daniel Jackson, an archaeologist who helps with understanding the different cultures. Samantha Carter, a brilliant scientist, is also a key character.

The main character in 'Dhalgren' is Bellona. He is a complex figure who navigates through the strange world of the story.

Some stories feature ordinary people who are suddenly thrust into extraordinary situations. They have to adapt and find ways to survive or make a difference in the face of advanced science - fictional elements, which makes their growth and transformation an interesting part of the story.

I'm not sure exactly as the details of 'The Wanderer' aren't fully known to me. But typically in a science fiction story, there could be an intrepid explorer as a main character. There might also be a scientist who is there to study the new phenomena they encounter.

Well, it could be a fearless explorer named Jack. He's always on the hunt for new Skully - related artifacts or knowledge. He has a tough exterior but a heart of gold.

Well, without more context, we can assume the pedestrian is one of the main characters. They are the central figure whose perspective we follow through the story.

Max is one of the main characters. He is from Earth and has a strong will to change his situation and reach Elysium. Then there's Kruger, who is sort of an antagonist. He's a brutal character who will do whatever it takes to maintain the status quo. And there's Frey, who gets involved with Max's plans.

I'm not sure specifically as there are many 'ark science fiction' works. But usually, there is a captain or leader figure who is responsible for making decisions on the ark. There might also be a scientist character who tries to understand the technology or the situation they are in.
