Antihero
The antihero became prominent in early 20th century existentialist works such as Franz Kafka's The Metamorphosis (1915), Jean-Paul Sartre's La Nausée (1938), and Albert Camus' L'Étranger (1942) (). The protagonist in these works is an indecisive central character who drifts through his life and is marked by ennui, angst, and alienation.
