superhero

A superhero is a fictional character who uses extraordinary abilities, advanced technology, or significant resources to protect the public and fight crime and threats beyond ordinary means. They typically operate in a setting where crime, tyranny, or existential danger is present. Common elements include a secret identity, a distinctive costume or emblem, and an origin story that explains how the powers or resources were acquired.

Originating in American comic books of the early 20th century, with pivotal figures such as the first popular superheroes in the 1930s, the genre expanded through the Golden, Silver, and Modern Ages, expanding themes, tone, and diversity. The concept has spread globally, influencing television, film, novels, and digital media.

Typical features include a dual life, a clear moral code, and a rogues' gallery of villains. Powers range from superhuman abilities to genius-level intellect, or the use of gadgets and technology. Many work alone or as part of teams; sidekicks and mentorships are common. The line between superhero and vigilante shows variation across works, with some heroes adhering to legal norms, others operating outside them.

Superheroes have become major cultural icons, shaping storytelling, merchandising, and visual design. Critiques address representation, ethics, violence, and the treatment of authority and power. The form remains dynamic, adapting to changing social attitudes and media platforms.
