The central character is the Invisible Man. He has a complex personality. There are also some supporting characters like the people he used to know before becoming invisible. For example, his colleagues or friends who now become the targets of his sometimes erratic behavior. And the police officers who are trying to figure out what's going on with all the strange happenings caused by the invisible man.
The themes include morality. He has to make moral choices about how to use his invisibility. There's also the theme of discovery. He's constantly discovering new things about his condition and how to interact with the world while invisible. And then there's the theme of being an outcast. People are afraid of him when they sense his presence, so he's cast out from normal society.
The central character is the invisible man. He is the focus of the story's exploration of his condition and its consequences. Other important characters could be the scientists or researchers who might be involved in the events leading to his invisibility. And perhaps there are some ordinary people who cross his path and have to deal with his invisibility in different ways.
One of the main themes is isolation. The invisible man is set apart from society due to his condition. Another theme could be power and its abuse. His invisibility gives him a certain power which he may use in different ways, some of which might be considered unethical. Also, identity is a key theme. He struggles with his own identity as an invisible being in a world that doesn't understand or accept him.
