An "outsider" or "alien" typically refers to someone or something that is not part of a particular group, society, or environment. This term can apply to individuals from different cultures, countries, or social circles, highlighting their differences from the majority. In a broader context, it can also refer to beings from other planets or dimensions, often depicted in science fiction. In literature and media, outsiders are often portrayed as characters who face challenges due to their differences. They may struggle to fit in or be accepted by the group, leading to themes of isolation and belonging. Examples include E.T., the extraterrestrial from the film, and Frankenstein's monster, who is shunned by society.
