NightWing is the grown up version of Robin. He becomes NightWing after joining the Teen titans. But he only joined TT because Bats dropped him!! And he still got two other Robins!! It's so screwed up!!!!!
alright nightwing is dick grayson who was the first robin he left cause he wanted to break out on his own so tim drake took dick's place as robin but now tim goes by red robin jason todd was a loose cannon that's why he's never mentioned on the show then there's damian wayne who i believe is bruce's son or foster son so now damian is the new robin in the comics
