De eerste aflevering van het nieuwe seizoen is vanaf 5 oktober te zien en wordt als volgt omschreven:
“After Laurel’s death and the departures of both Diggle and Thea from Team Arrow, Oliver takes to the streets solo to protect Star City’s citizens as the Green Arrow. With Felicity guiding him from the bunker, Oliver is forced to deal with a city that has become overrun with both criminals and a slew of new (and painfully inexperienced) vigilantes. Watching Oliver try to balance his jobs as both the mayor and also the protector of Star City, Felicity suggests he form a new team, but Oliver resists. However, when a deadly new criminal, Tobias Church (guest star Chad L. Coleman), enters the picture, Oliver realizes the best thing for the city might be a new team of superheroes. Meanwhile, the flashbacks take us to Russia where Oliver faces off against the Bratva.”
Arrow heeft hoofdrollen voor Stephen Amell, David Ramsey, Willa Holland, Emily Bett Rickards, John Barrowman, Paul Blackthorne.
