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.
In the Ark Origin Story, the main characters might include visionary leaders. These are the people who had the foresight to plan for the Ark's creation. There could also be engineers and scientists as main characters. They would be responsible for making sure the Ark was functional and could support life. Additionally, there might be some ordinary people who played important roles, like those who provided the necessary labor or resources.
The main character was Noah. He was chosen by God to build the ark. His family members, including his wife, sons (Shem, Ham, and Japheth), and their wives, were also important characters as they were the ones who entered the ark with Noah.
Bellamy's character could be developed by showing his growth from a more self - centered person to someone who truly cares about the well - being of the Ark as a whole.

There are often the survivors. These are the people who manage to get on the 'ark' - whether it's a spaceship or an underground bunker. They are usually resourceful, like engineers who can keep the ark running or doctors who can deal with medical issues.
The most important character is Noah. He is the one chosen by God to build the ark and save his family and the animals. His family members, including his wife, sons, and their wives, are also important as they are part of the ones saved in the ark.
