A "Sidekick" is a character or person who assists and supports a main character, often in stories, movies, or comic books. They typically provide help, comic relief, or companionship, enhancing the narrative and the main character's journey. Famous examples include Robin from Batman and Samwise Gamgee from The Lord of the Rings. In real life, a sidekick can refer to a friend or colleague who plays a supportive role in various activities or projects. This relationship often involves teamwork, where the sidekick complements the skills of the main individual, making tasks easier and more enjoyable.
