Billionaire playboy and orphan Oliver Queen is Green Arrow, armed with an arsenal of arrows including trick arrows which can serve a variety of purposes, such as grappling hook arrows or explosive arrows. Like Batman, the Green Arrow possesses no inherent superpowers but commands a vast personal wealth, fighting skills and an accuracy with a bow and arrow that is unmatched. His first speaking role was season 5's "Vertigo", in which he battled and took down former employee and old nemesis Count Vertigo. He is voiced by Chris Hardwick.
