Arrow has always been presented as the hero's journey of Oliver Queen as shown over a period of five years.

Season 6. On March 11, 2016, Arrow was renewed for a fifth season by The CW. It premiered on October 5, 2016. It took place in conjunction with the third season of The Flash, the second season of Supergirl and the second season of DC's Legends of Tomorrow.
