The term "sidekick" typically refers to a close companion or assistant who accompanies someone, often a person with more prominence or leadership. The sidekick is usually a loyal and supportive individual, providing assistance, friendship, or comedic relief to the main character. In literature, movies, or TV shows, the sidekick is a character who is not the primary focus but plays a significant role in the story. The sidekick's characteristics can vary widely, ranging from being a superhero's loyal friend to a detective's assistant or a protagonist's humorous companion. The term is often associated with fictional works, but it can also be used informally to describe a person who regularly accompanies or supports someone in real life.
