Nightwing fighting the bad guys aside Catwoman, Huntress and Black Canary... hmmm... superb team-up, man! Cracking whips, flying escrima sticks, pointy arrows and piercing canary cries galore, no doubt!
Just one question: why isn't Catwoman wearing a mask? Has she given up her secret identity or something? She reminds me of the 60's Catwoman, by the way (Julie Newmar).
As for the people in the background, I can only recognize The Riddler because the rest... are totally unknown to me. Care to help me with this, gambaryance?
