Dick Grayson, full name Richard John Grayson, was the first Robin
, and the second Batman
. Now back to being Nightwing again. Contrary to what the contributor before me believes, he's never died. The contributor before me is probably thinking of Jason Todd
, the second Robin, or Damian Wayne
, the fifth.
Anyways, he's also been the leader of the Teen Titans, the Outsiders, ext. His most important and long-lasting "love-interests" are Barbara Gordon
. His parents died when he was young and so Bruce Wayne
sort-of adopted him (he took him as a "ward", if that even means something anymore). And he's way cooler than you so I suggest reading a few comics before you judge.
