When Supergirl premiered in 2015, few expected it would become one of the defining series of the Arrowverse. Over six seasons and 126 episodes, the show transformed Melissa Benoist’s Kara Danvers into a fan-favorite superhero while introducing memorable characters like Alex Danvers, Lena Luthor, Martian Manhunter, Dreamer, and Brainiac-5.
Although the series concluded in 2021, the cast has remained active across television, film, voice acting, and streaming projects. Some stars have continued working within the comic-book genre, while others have explored entirely new creative directions.
So where are the Supergirl cast members now?
Let’s take a look at what the Arrowverse stars have been doing since leaving National City behind.
1. Melissa Benoist (Kara Danvers / Supergirl)
No actor is more closely associated with Supergirl than Melissa Benoist.
Her portrayal of Kara Danvers helped define the character for an entire generation of fans, and many viewers still consider her one of the best live-action DC heroes ever cast. Recent fan discussions continue to praise her performance even years after the show’s conclusion.
Since Supergirl ended, Benoist has expanded her career beyond the superhero genre. She starred and executive produced the HBO political drama The Girls on the Bus and later joined Netflix’s crime drama The Waterfront. She also voiced Teela in Masters of the Universe: Revolution.

Benoist remains one of the most successful alumni from the Arrowverse era.
2. Chyler Leigh (Alex Danvers)

After Supergirl, Leigh transitioned into a major role on Hallmark’s hit time-travel drama The Way Home, which has become one of the network’s most successful modern series. She also briefly returned to the Arrowverse during The Flash’s “Armageddon” event.
Current Status
Leigh continues to thrive in television while expanding her directing experience gained during Supergirl’s later seasons.

4. David Harewood (Martian Manhunter)
David Harewood delivered one of the Arrowverse’s most underrated performances as J’onn J’onzz, better known as Martian Manhunter.
His character provided wisdom, leadership, and emotional stability throughout the show’s entire run.
Following Supergirl, Harewood diversified his career significantly. He contributed voice work to major projects including Alan Wake II and The Sandman audio adaptation while also appearing in television series such as The Acolyte, Sherwood, and Happy Face. He additionally became President of the Royal Academy of Dramatic Arts (RADA).
Current Focus

- Voice acting
- Theater leadership
- Industry mentorship
Few cast members have built a post-Supergirl résumé as varied as Harewood’s.
6. Nicole Maines (Nia Nal / Dreamer)
Nicole Maines made television history when Dreamer became the first transgender superhero featured as a major character in a TV series.
The role became one of the most important additions to Supergirl’s later seasons and earned praise from fans and critics alike.
Since the show ended, Maines has continued building an impressive acting career. She appeared in Good Trouble and became part of the acclaimed thriller series Yellowjackets, where she portrayed Lisa. She later returned for additional appearances.
What’s Next?
Maines continues to be one of the fastest-rising talents from the Supergirl ensemble.
7. Mehcad Brooks (James Olsen)
James Olsen played a major role throughout the early years of Supergirl.
After leaving the series, Mehcad Brooks successfully transitioned into one of network television’s most recognizable crime-drama stars.
He joined NBC’s Law & Order franchise as Detective Jalen Shaw, becoming one of the central faces of the long-running procedural. He also appeared in And Just Like That….
Career Highlights Since Supergirl
- Lead role in Law & Order

Among the cast, Brooks arguably made one of the smoothest transitions into another major television franchise.
8. Jesse Rath (Brainiac-5)
Jesse Rath’s Brainiac-5 became increasingly important during the later seasons of Supergirl.
His combination of humor, intelligence, and emotional growth helped turn Brainy into one of the show’s most beloved characters.
Since the series ended, Rath has continued working across television and voice acting projects while remaining a favorite among comic-con audiences and Arrowverse fans.
Fan Legacy
Many viewers still consider Brainiac-5 one of the strongest additions introduced during the CW era.
9. Chris Wood (Mon-El)
Chris Wood’s Mon-El generated some of the show’s biggest storylines and fan debates.
After Supergirl, Wood continued acting while also participating in voice projects. He notably joined Masters of the Universe: Revolution, reuniting with Melissa Benoist in a different franchise.
His connection to Supergirl remains especially notable because he and Benoist married after meeting during the show’s production.
Why the Supergirl Cast Remains Popular Years Later
One reason the cast continues to enjoy strong fan support is the emotional connection viewers formed with the characters.
Unlike many superhero shows that focused primarily on action, Supergirl emphasized:
- Family relationships
- Friendship
- Hope
- Identity
- Personal growth
These themes helped create lasting attachment among audiences.
Recent online discussions still describe Melissa Benoist as ideal casting for Kara Danvers, demonstrating the enduring affection fans have for the series.
