Comic book characters are fictional figures that appear in comic books, which are illustrated publications that tell stories through a combination of images and text. These characters often possess unique abilities, personalities, and backstories, making them memorable and engaging for readers. Popular examples include Superman, Batman, and Spider-Man, each with their own distinct traits and adventures. Many comic book characters belong to larger universes, such as Marvel or DC Comics, where they interact with other characters and face various challenges. These characters can be heroes, villains, or anti-heroes, and their stories often explore themes of justice, morality, and identity.
