As the Green Arrow, he protects his city with the help of former soldier John Diggle, computer-science expert Felicity Smoak, his vigilante-trained sister Thea Queen, Deputy Mayor Quentin Lance, brilliant inventor Curtis Holt, and his new recruits, street-savvy Rene Ramirez and meta-human Dinah Drake.
