Robin is the alias of several fictional superheroes appearing in American comic books published by DC Comics. While there have been numerous characters who have assumed the role of Robin, the most well-known is Dick Grayson, the original Robin. As Batman's sidekick, Robin is an integral part of the Batman universe, bringing a youthful energy and a contrasting dynamic to Batman's dark persona. Robin serves as a symbol of hope and resilience, often providing emotional support and a moral compass to Batman. Over time, Robin has evolved into a hero in his own right, sometimes leading the Teen Titans and adopting new aliases like Nightwing.
