Crime Alley
Teen Titans #44 (1984) The older Dick Grayson becomes tired of his role as Batman's sidekick. He calls himself Nightwing after a local hero he and Batman met in the Kryptonian city of Kandor.
Over the edge
In the classic 1960s "Batman" television series, Robin the Boy Wonder's character name was Dick Grayson. He served as Batman's sidekick and was portrayed by actor Burt Ward. The show highlighted their dynamic partnership as they fought crime together in Gotham City.
Robinson Crusoe's sidekick is named Friday.
Batman's name is Batman. However his secret identity is Bruce Wayne.
Dick Grayson went solo when he grew up and so he would no longer be in the Teen Titans or be Batman's sidekick. You probably already know this but just in case you don't know he took the name Nightwing when he became a full grown man. Tim Drake became Red Robin when he grew out of being Batman's sidekick as well. Jason Todd became the Red Hood. I hope this information helped you! :)
