Carbon Costume

Onomatopoeia is a villian from the DC Comics. He first appeared in Green Arrowvolume 3, #12, written by Kevin Smith and illustrated by Phil Hester. He is often an enemy of Green Arrow and Batman, only speaking in noises as per his namesake. He is a master marksman with advanced handgun training. For this costume guide, the white paint to draw the circles onto the balaclava.

In Arrow, Oliver Queen (Stephen Amell) is Green Arrow, a billionaire playboy who dons a costume and fights crime. Sounds a lot like another guy we know. No surprise that his weapon of choice is the bow and arrow.
