I am a HUGE fan of a show called "Young Justice", witch is a show about teenaged heroes such as Robin, Kid Flash, Aqualad, Superboy, Miss.Martian, and Artemis. Well in the second season the leader of the Team is a character that goes by the name Nightwing (who was the first Robin). So you can guess the shock I felt when I found out that Nightwing was also the name of the villain in the Guardian Herd. Just figured I share this because I thought it was interesting.
(P.S. this is what the Nightwing from Young Justice looks like)
