List of supporting Arrow characters
Arrow is an American superhero television series developed by Greg Berlanti, Marc Guggenheim, and Andrew Kreisberg based on the DC Comics character Green Arrow, a costumed crime-fighter created by Mort Weisinger and George Papp, and is set in the Arrowverse, sharing continuity with other Arrowverse television series. The series premiered in the United States on The CW on October 10, 2012, with international broadcasting taking place in late 2012 and primarily filmed in Vancouver, British Columbia, Canada. Arrow follows billionaire playboy Oliver Queen, who claimed to have spent five years shipwrecked on Lian Yu, a mysterious island in the North China Sea, before returning home to Starling City to fight crime and corruption as a secret vigilante whose weapon of choice is a bow and arrow.
Throughout the series, Oliver is joined by others in his quest, among them former soldier John Diggle, I.T. expert and skilled hacker Felicity Smoak, former assassin Sara Lance, aspiring vigilante Roy Harper, Oliver's sister Thea, and attorney-turned-vigilante Laurel Lance. The group also receives support from Laurel and Sara's father Officer Quentin Lance. During the first five seasons of the show, characters from Oliver's past appear in a separate story arc based on Oliver's flashbacks, which highlight parallels from Oliver's history that shape events in the main story. Starting with season seven, a series of flash-forwards focus on Oliver's children William and Mia, exploring how present events would affect their future and Green Arrow's legacy.
