It's hard to give an exact number as it depends on how you define a significant character. But there are quite a few, including the protagonist and various supporting characters who play important roles in the story.
The Invisible Man himself is the most important character. He is the one whose experiences we follow throughout the story. Then there are the scientists who play a role in making him invisible. They represent the power of science and also the irresponsibility that can come with it.
The invisible man himself is the most important character. He is the narrator and his journey forms the core of the story. Then there is Dr. Bledsoe, who represents the authority within the black community but also has his own self - serving motives.
The invisible man himself is of course the most important character. He is the one through whose perspective we see the story unfold.
Mary Rambo is warm - hearted. She is not wealthy but she shares what she has with the Invisible Man. She has a simple life but her heart is big. She is a contrast to the more self - centered characters like Dr. Bledsoe, and she provides a glimmer of hope and humanity in the Invisible Man's otherwise dark and tumultuous journey.
The main character is the Invisible Man himself. He is a complex figure who experiences invisibility and the alienation that comes with it.
The central character is the Invisible Man. His character development from an ordinary person to one with the power of invisibility and how he copes with it is key. There are also the scientists he might have come across. They play a role in either trying to understand his condition or fearing it. And the people in the places he hides or tries to live among, they all add to the story.
There are likely some characters who interact with the invisible man. For example, there might be a scientist who was involved in the process that made him invisible. This character could have added some backstory and understanding of how the invisibility came about.
The rustic characters in the 'Invisible Man' are also important in terms of the novel's overall theme of identity. They have a more straightforward sense of who they are, rooted in their rural upbringing and community. This stands in contrast to the protagonist's journey of self - discovery in a world that often tries to define and control him. Their presence helps to highlight the protagonist's struggle and the hollowness of some of the identities imposed on him in the urban and more 'civilized' settings.
The central character is without a doubt the Invisible Man. He is complex, initially a brilliant but somewhat obsessive scientist. His invisibility causes him to lose his sense of self and his morality. Another key character is Dr. Kemp. He is a learned man, and his interactions with the Invisible Man are crucial to the story. At first, he is intrigued by the Invisible Man's situation, but as he discovers the Invisible Man's malevolent intentions, he becomes an adversary. Additionally, the townspeople play a role as well. Their fear and confusion in the face of the Invisible Man's actions add to the overall atmosphere of the novel.
The invisible man himself is of course very important. He is the main character around whom the whole story revolves. His actions and his inner thoughts drive the narrative forward. Then there are the people he interacts with, like Dr. Kemp. Dr. Kemp is initially a friend to the invisible man but later turns against him when he realizes the danger the invisible man poses.
