The CW’s Arrow ran for eight seasons from 2012 to 2020, building a dedicated fanbase around its gritty take on the Green Arrow mythos. At its centre was a core cast of actors whose characters evolved dramatically over the course of the series. This article provides a complete, season-by-season breakdown of the cast of Arrow, examining the main players, recurring roles, and key transitions that defined the show.
Understanding who appeared in each season helps clarify how the show’s ensemble grew from a tight group of Starling City residents into an expanded team of vigilantes. Two actors, Stephen Amell and David Ramsey, remained with the series for its entire run, while others came and went as the story demanded.
Cast of Arrow TV Series Season 1
The first season introduced the core characters who would anchor the show for years to come. The cast of Arrow TV series season 1 centred on Oliver Queen’s return to Starling City and his early crusade against the wealthy elites listed in his father’s notebook.

Cast of Arrow TV Series Season 4
By season 4, the cast of Arrow TV series had settled into a familiar rhythm, though significant changes were already underway. John Barrowman was promoted to series regular for seasons 3 and 4, and the season four finale marked the death of Earth-1 Laurel Lance, played by Katie Cassidy.
The season also introduced Echo Kellum as Curtis Holt, who began as a recurring character before becoming a main cast member in season 5. The cast of Arrow TV series season 4 thus represents a transitional period where the original team began to fracture while new members were being prepared for larger roles.
Main Cast of Season 4
- Stephen Amell as Oliver Queen / Green Arrow
- Katie Cassidy as Laurel Lance / Black Canary
- David Ramsey as John Diggle
- Emily Bett Rickards as Felicity Smoak
- Willa Holland as Thea Queen
- Paul Blackthorne as Quentin Lance
- John Barrowman as Malcolm Merlyn / Ra’s al Ghul
- Neal McDonough as Damien Darhk (main)
Laurel Lance (Earth-1) dies in the season four finale, a major turning point. Katie Cassidy later returned as the Earth-2 version of the character, Black Siren, who was promoted to series regular from season 6 onward.
Cast of Arrow TV Series Season 6
The cast of Arrow TV series season 6 saw the largest ensemble yet. Following the loss of Earth-1 Laurel, the show introduced a new Black Canary in Dinah Drake, played by Juliana Harkavy, who had joined as a recurring character in season 5 before being promoted to main cast status.
Rick Gonzalez played Rene Ramirez / Wild Dog, also promoted from recurring to main cast from season 6. Echo Kellum continued as Curtis Holt / Mr. Terrific. The expanded Team Arrow now included five active vigilantes alongside Oliver Queen.
Main Cast of Season 6
- Stephen Amell as Oliver Queen / Green Arrow
- David Ramsey as John Diggle
- Emily Bett Rickards as Felicity Smoak
- Echo Kellum as Curtis Holt / Mr. Terrific
- Rick Gonzalez as Rene Ramirez / Wild Dog
- Juliana Harkavy as Dinah Drake / Black Canary
- Paul Blackthorne as Quentin Lance
- Katie Cassidy as Earth-2 Laurel Lance / Black Siren (recurring season 5, main seasons 6-8)
Season 6 also featured the death of Quentin Lance in the season finale. The character later returned after Oliver restored the multiverse in the series finale, effectively resetting certain deaths from the show’s timeline.
Cast of Arrow TV Series Season 7
By season 7, the cast of Arrow TV series had shifted again. Colton Haynes returned as a main cast member for season 7, having previously been a series regular in seasons 2 and 3. Roy Harper / Arsenal had been absent as a main character for several seasons before his return.
Ben Lewis joined as the older version of William Clayton, Oliver’s son, first as a recurring character in season 7 and then as a main cast member in season 8. Joseph David-Jones also appeared as the older Connor Hawke in season 7 before being promoted to main cast for the final season.
Main Cast of Season 7
- Stephen Amell as Oliver Queen / Green Arrow
- David Ramsey as John Diggle
- Emily Bett Rickards as Felicity Smoak
- Echo Kellum as Curtis Holt / Mr. Terrific
- Rick Gonzalez as Rene Ramirez / Wild Dog
- Juliana Harkavy as Dinah Drake / Black Canary
- Katie Cassidy as Earth-2 Laurel Lance / Black Siren
- Colton Haynes as Roy Harper / Arsenal
Emily Bett Rickards departed the series at the end of season 7, and Felicity Smoak did not appear in season 8 as a main cast member. Her character’s story concluded in the series finale flashforward sequences.
Cast of Arrow TV Series Laurel
The character of Laurel Lance carries one of the most complex arcs in the series, and it is handled by two distinct versions across multiple Earths. The cast of Arrow TV series Laurel is essentially a story of one actor playing two roles: Katie Cassidy portrayed both Earth-1 Laurel and Earth-2 Laurel.
Earth-1 Laurel Lance
Katie Cassidy played the original Laurel Lance as a main cast member from seasons 1 through 4. The character began as an assistant district attorney and Oliver Queen’s former girlfriend, before training to become the vigilante Black Canary. She died in the season four finale, though she continued to appear in later seasons through flashbacks, visions, and alternate universe versions.
Earth-2 Laurel Lance / Black Siren
Following the death of Earth-1 Laurel, an antagonistic doppelgänger from Earth-2 was introduced. This version, known as Black Siren, originally appeared on The Flash before being promoted to series regular on Arrow for seasons 6, 7, and 8. Over the course of the series, Black Siren redeems herself and eventually returns to Earth-2 as its heroic Black Canary.
Character Complexity
The role of Laurel Lance maintains a complex link with Oliver Queen, despite romantic entanglements and betrayals. In DC Comics canon, Black Canary is a frequent romantic interest of Green Arrow, but the Arrow television adaptation shifted Oliver’s primary romantic focus to Felicity Smoak, played by Emily Bett Rickards.

What Is Confirmed and What Remains Unclear About the Arrow Cast
The cast of Arrow TV series is well-documented through official credits, IMDb listings, and network announcements. Most information about who played which character and when is publicly confirmed. However, there are areas where the distinction between different versions of characters can cause confusion.
| Established information | Information that remains unclear |
|---|---|
| Stephen Amell and David Ramsey appeared in all 8 seasons as main cast members. | Whether future Arrowverse projects will feature the same actors in the same roles is not confirmed. |
| Katie Cassidy played two distinct versions of Laurel Lance across multiple seasons. | The exact number of episodes in which Cassidy appeared as each version is not always clearly separated in general-reference materials. |
| Emily Bett Rickards was a main cast member for seasons 1 through 7. | Her potential return in future spin-offs has not been officially announced or denied by producers. |
| Colton Haynes had a complex status across seasons, being main cast, recurring, and special guest at different points. | The reasoning behind specific casting decisions for individual seasons is not always publicly available. |
Why the Arrow Cast Evolved the Way It Did
Arrow maintained relatively stable casting compared to other Arrowverse productions. The series did not experience the significant recasting issues that affected other shows in the shared universe, such as Batwoman’s recast of Kate Kane in season 2. Instead, Arrow chose to expand its cast by introducing new characters and promoting existing ones to series regular status.
Several actors who began as recurring or guest performers were elevated to series regular status. John Barrowman started as a recurring actor in seasons 1 and 2 before becoming a series regular in seasons 3 and 4. Manu Bennett was initially cast as recurring for season one before receiving series regular status in season two. This pattern of promotion helped the show build loyalty among its cast while keeping the ensemble fresh.
The series finale in season 8 reunited several characters from across the show’s run, including appearances from actors who had left the main cast in previous seasons. This approach allowed the show to honour its history while concluding the story of Oliver Queen and the team that surrounded him.

Summary: The Arrow Cast in Perspective
The cast of Arrow TV series evolved from a core team of seven actors in season one to an expanded ensemble of nine or more main cast members by seasons 6 and 7, before contracting again for the abbreviated final season. Throughout these changes, the permanent presence of Stephen Amell and David Ramsey provided continuity, while the introduction of new Team Arrow members such as Wild Dog, Mr. Terrific, and a new Black Canary kept the series fresh. The Arrow cast and characters remain one of the most discussed aspects of the show, particularly the handling of Laurel Lance across two Earths and the Arrow TV series main cast throughout seasons.
