The ninth and final season ofThe Flashwill feature the return ofStephen AmellasGreen Arrow;it has been confirmed. Amell began The CW shared universe way back in 2012 with the first season ofGreen Arrow, which introduced the actor as billionaire playboy Oliver Queen, who is transformed into the DC superhero Green Arrow after being shipwrecked, gaining a penchant for archery, and returning to Star City to fight crime and corruption.
Running for eight seasons,Green Arrowbecame a staple of The CW universe (aka The Arrowverse) with the friendship growing between Amell’s Oliver Queen and Grant Gustin’s Barry Allen, aka The Flash, as both shows and their crossovers went on. A friendship that fans of both shows will be hugely excited to see once again on-screen during the final season ofThe Flash.

“As soon as our final season was announced, we knew we wanted Stephen to come back and reprise his iconic role as Oliver Queen,“The Flashshowrunner Eric Wallace said in a statement toDeadlineregarding Stephen Amell’s return. “After all, it was Oliver who originally launched Barry Allen on his heroic path. That’s why everyone on Team Flash felt so strongly that it was important to create a full-circle moment with Oliver’s return in the final season of The Flash. The result is an epic-yet-emotional episode we hope Arrowverse fans will enjoy. It’s all to say ‘thank you’ to everyone for watching and supporting our show throughout nine wonderful years. We absolutely cannot wait for everyone to see Grant and Stephen saving the world together again. And yes, there will be thrills, chills and tears.”
