An antihero is a main character in a story who lacks conventional heroic qualities and attributes, such as idealism, courage, and morality. They are often defined by their own self-interest and may make selfish decisions that put others in danger. Antiheroes tend not to have the same kind of character arc as traditional heroes, and their motivation for doing good usually doesnt come from wanting to be a hero themselves, but rather from other reasons such as seeking revenge or trying to make up for past mistakes. Some common characteristics of antiheroes include:

• Lack of morality: Antiheroes often lack strong morals and may do things that are considered wrong or unethical.

• Selfishness: They tend to make decisions that benefit themselves, even if it means putting others in danger.

• Rejection of social conventions: Antiheroes often feel rejected by society and may go down a self-destructive path that results in isolation or death.

• Complexity: Antiheroes are often more complex than traditional heroes, with interesting flaws and motivations that make them fascinating to watch.

Examples of antiheroes include Walter White from Breaking Bad, Tony Soprano from The Sopranos, and Michael Corleone from The Godfather. Its important to note that antiheroes are not the same as anti-villains, who are characters that are opposed to the hero but still have heroic qualities.
