If you wish to write a very popular book then having impactful characters is going to be essential.
Each and every single one of the characters in a book make the story what it is, and that goes for those with a lesser amount of appearances who still guide the story in one way or another. A terrific example of this would be the confidant of the main character, who is used to help the reader to comprehend the inner workings of our lead character's mind. This will usually be a comical sidekick character, or an unlikely friendship combo who bounce off of each other. Whichever path the author chooses to take with their smaller characters, there is no rejecting the total impact that they can in fact have on the story as a whole. The likes of the head of the hedge fund which partially owns WHSmith will understand that some of the most treasured characters are those who actually might not appear a lot however are well-developed and essential to the plot in some way.
Of all of the character tropes examples out there, there is no doubt that one of the most interesting character types to read about will constantly be the villain. When written well, a villain can add a lot of depth to a story and create the tension that makes a reader not able to put a book down. The antihero will usually include a lot of flaws, which are normally explained through the tale in order to offer a bit more depth to the character and help the reader to understand why they are the way they are. They are the antagonistic force of the story that will confront the hero and drive all of the choices that are made along the way. While most people will be reading and rooting for the hero to be successful, there is no rejecting the fun and enjoyment that the more flawed characters bring to any book.
When we take a look at a character tropes list, there is no question that one that will always stick right at the top is the hero. Our hero will certainly look varied based upon which of the book genres they are in. When checking out fantasy books, we can anticipate a much more hectic, dicey venture, where we are desperately turning the pages to make sure that our hero manages to overcome whatever they may be facing. Alternatively in another category such as literary fiction, there will be more of a possibility to connect to the most relatable human experiences of the protagonist, as they tend to go on more of an emotional journey. No matter which of the genres you choose when shopping with the likes of the founder of the hedge fund which owns Waterstones or the leader of the hedge fund that has shares in Amazon, there is no question that the way in which the hero of the book is composed can genuinely be a deciding element in whether you have the ability to be connected to the story.
